An overview of acupuncture for the treatment of limb spasticity in cerebral palsy-A mini review

Cerebral palsy is a common chronic disabling disease in children with special needs,and rehabilitation for cerebral palsy is characterized by a long period,multiple methods and limited efficacy.Due to the limited motor function of cerebral palsy patients,the quality of life of patients is reduced,and their ability to participate in society is reduced,so the improvement of patients’motor function has become an important goal of cerebral palsy rehabilitation.The motor function of cerebral palsy has become an important goal of cerebral palsy rehabilitation.Limb spasticity is one of the main clinical signs of cerebral palsy patients,and the more severe the limb spasticity is,the greater the impact on the patient's motor function,so improving limb spasticity in patients with cerebral palsy is particularly important.Acupuncture,as a Chinese medicine treatment method,has been widely used in the clinical treatment of cerebral palsy in China,and has shown certain efficacy.To promote the clinical application of acupuncture technique in cerebral palsy limb spasticity,this paper analyses and summarizes the relevant literature on acupuncture treatment of cerebral palsy limb spasticity summarizes the current status of the clinical application of acupuncture in cerebral palsy limb spasticity,and provides clinical references for the reasonable application of acupuncture in cerebral palsy limb spasticity.

Comprehensive Rehabilitation Therapy of Traditional Chinese Medicine Combined with Modern Rehabilitation Training Improves the Spasticity and Motor Function of Hemiplegia after Stroke

Objective:To analyze the impact of comprehensive rehabilitation therapy of traditional Chinese medicine(TCM)(based on modern rehabilitation training)on the spasticity and motor function in stroke patients with hemiplegia.Methods:Seventy-nine stroke and hemiplegia patients admitted to the hospital from June 2021 to June 2023 were selected and randomly divided into a control group(39 cases)using modern rehabilitation training,and an observation group combined with comprehensive TCM rehabilitation therapy(40 cases),over 1 month.The clinical index data of the two groups were compared.Results:There were differences in the clinical index data between the two groups.The total effective rate after 2 treatment in the observation group(92.50%)was higher than that of the control group(74.36%)(χ^(2)=4.727,P<0.05).All central sensitization inventory(CSI)and stroke quality of life(PRO)scores in both groups were lower after treatment,with the observation group having lower scores as compared to the control group(P<0.05).The scores of FMA(upper limbs,lower limbs),Barthel index scores,and Functional Ambulation Categories(FAC)scores of both groups increased after treatment,with the observation group having higher scores as compared to the control group(P<0.05).Conclusion:Comprehensive TCM rehabilitation therapy had a significant therapeutic effect on patients with hemiplegia after stroke.It improved the patient’s spasticity,limb movement,and walking function.Their daily living abilities and quality of life were also enhanced.

Association between brain N-acetylaspartate levels and sensory and motor dysfunction in patients who have spinal cord injury with spasticity:an observational case-control study

Spinal cord injury is a severe and devastating disease,and spasticity is a common and severe complication that is notoriously refractory to treatment.However,the pathophysiological mechanisms underlying spasticity and its development remain largely unknown.The goal of the present study was to find differences,if any,in metabolites of the left precentral gyrus and basal ganglia of patients who have spinal cord injury with or without spasticity,and to explore the relationship between the brain metabolite concentrations and clinical status.Thirty-six participants were recruited for magnetic resonance spectroscopic examination:23 with spinal cord injury(12 with spasticity and 11 without spasticity)and 13 healthy controls.We acquired localized proton spectra from the precentral gyrus and basal ganglia via 10 mm^(3) voxels.Notably,univariate linear regression analysis demonstrated that the lower that the N-acetylaspartate concentration(a marker for neuronal loss)was in the precentral gyrus of the patients,the lower their ASIA(American Spinal Injury Association)light-touch scores,pinprick scores,and motor scores.Additionally,longer durations of injury were associated with higher N-acetylaspartate levels in the precentral gyrus.Compared with the healthy participants and patients without spasticity,N-acetylaspartate levels in the patients with spasticity were significantly lower in both the precentral gyrus and basal ganglia.Lower N-acetylaspartate levels also correlated with greater sensory and motor dysfunction in the patients who had spinal cord injury with spasticity.

Extracorporeal shock wave for plantar flexor spasticity in spinal cord injury:A case report and review of literature

BACKGROUND Approximately 65%-78%of patients with a spinal cord injury(SCI)develop any symptom of spasticity.The aim of this study was to investigate the tolerability and short-term effects of radial extracorporeal shock wave therapy(r ESWT)on plantar flexor spasticity in a patient with incomplete SCI.CASE SUMMARY An 18-year-old man with an incomplete SCI completed five sessions of r ESWT.The primary outcomes were the changes in ankle-passive range of motion(APROM)and passive resistive force to ankle dorsiflexion.The outcomes were assessed at baseline(T0),immediately after treatment(T1)and 1 wk after the end of treatment(T2).The A-PROM increased by 15 degrees at T1 and 25 degrees at T2 compared with T0.The passive resistive force to ankle dorsiflexion at low velocity decreased by 33%at T1 and 55%at T2 in the gastrocnemius muscle and by 41%at T1 and 39%at T2 in the soleus muscle compared with T0.At high velocity,it also decreased by 44%at T1 and 30%at T2 in the gastrocnemius muscle compared with T0.However,in the soleus muscle,the change was minor,with a decrease of 12%at T1 and increased by 39%at T2 compared with T0.CONCLUSION In this patient,the findings showed that r ESWT combined with conventional therapy was well-tolerated and could be effective in improving A-PROM and passive resistive force to ankle dorsiflexion in the short-term.Further randomized controlled clinical trials with longer period of follow-up are necessary to confirm the results obtained in patients with SCI.

Novel mutation of SPG4 gene in a Chinese family with hereditary spastic paraplegia:A case report

BACKGROUND Hereditary spastic paraplegia(HSP)is a group of neurogenetic diseases of the corticospinal tract,accompanied by distinct spasticity and weakness of the lower extremities.Mutations in the spastic paraplegia type 4(SPG4)gene,encoding the spastin protein,are the major cause of the disease.This study reported a Chinese family with HSP caused by a novel mutation of the SPG4 gene.CASE SUMMARY A 44-year-old male was admitted to our hospital for long-term right lower limb weakness,leg stiffness,and unstable walking.His symptoms gradually worsened,while no obvious muscle atrophy in the lower limbs was found.Neurological examinations revealed that the muscle strength of the lower limbs was normal,and knee reflex hyperreflexia and bilateral positive Babinski signs were detected.Members of his family also had the same symptoms.Using mutation analysis,a novel heterozygous duplication mutation,c.1053dupA,p.(Gln352Thrfs*15),was identified in the SPG4 gene in this family.CONCLUSION A Chinese family with HSP had a novel mutation of the SPG4 gene,which is autosomal dominant and inherited as pure HSP.The age of onset,sex distribution,and clinical manifestations of all existing living patients in this family were analyzed.The findings may extend the current knowledge on the existing mutations in the SPG4 gene.

Expression of DRD1 mRNA after Spinal Cord Injury Induced Spasticity in Rats

[Objectives]To investigate the spasticity of rat tail and the expression of dopamine receptor-1(DRD1)mRNA in the spinal cord after spinal cord injury(SCI)induced tail spasticity in rats.[Methods]Adult male Wistar rats were randomly divided into Sham group and SCI group.The second sacral spinal cord(S2)segment of SCI rats was completely transected.60 d after operation,the rat tail spasticity was scored,and then the spinal cord tissues below the level of S2 spinal cord transection were taken.The expression of DRD1 mRNA in the sacrococcygeal spinal cord was detected by qPCR.In addition,3 normal rats were used for DAR/neuronal nuclei(NeuN)and DRD1/choline acetyltransferase(ChAT)immunofluorescence staining to study the distribution of DRD1 in spinal cord and the properties of DRD1 positive cells.[Results]60 d after operation in SCI group,the tail spasticity of rats developed fully,and the symptoms of spasticity were typical.qPCR results showed that the expression of DRD1 mRNA in SCI group was significantly lower than that in Sham group(P<0.05).DRD1 was widely distributed in the dorsal horn,intermediate zone and ventral horn at the sacrococcygeal end of the rat spinal cord.[Conclusions]The decrease of DRD1 mRNA expression after SCI may be related to the occurrence and development of spasticity.

Systematic evaluation of the efficacy and safety of botulinum toxin type A in the treatment of spastic cerebral palsy

Background:Botulinum toxin type A(BTX-A)is a neuromuscular blocking agent.BTX-A inhibits acetylcholine release,causes neuromuscular transmission impairment,and decreases muscle spasms.Objective:To explore the efficacy and safety of BTX-A injection in the treatment of spastic cerebral palsy through systematic evaluation and to provide a reference for the clinical use of BTX-A.Methods:We used“Cerebral palsy”and“BTX-A”as the subject terms and used a combination of subject terms and free words for the search.We searched 7 databases,including CNKI,Wanfang,VIP,Sinomed,PubMed,Embase,and Web of science.Based on the inclusion and exclusion criteria,we screened the articles by reading their titles,abstracts,and full texts and finally included relevant literature for systematic evaluation.Result:A total of 93 papers were systematically evaluated,revealing that BTX-A injection treatment can effectively reduce muscle tone,increase joint mobility,improve gait and motor posture,and enhance gross motor movements in patients with spastic cerebral palsy.The benefits of BTX-A treatment can be sustained for 3–6 months,with motor ability improvement lasting up to 1 year.Combining BTX-A treatment with rehabilitation or external fixation therapy can enhance its efficacy.However,the effectiveness of BTX-A treatment is influenced by several factors,such as the dosage,number of injections,and patient age.Adverse reactions to BTX-A treatment are typically mild and can be relieved within 1–2 weeks.Conclusion:BTX-A injection is relatively safe but reversible.

Effects of Microselective Neurotomy on Focal Spasticity and Description of the Surgical Technique

We studied the microselective neurotomy (MSN) and its advantages to alleviate disabling spasticity. The best indication for MSN is focal spasticity. We performed 298 MSN, 87 nerves on the upper limb, 211 nerves on the lower limb) in 68 patients. The initial causes were: stroke, cranial trauma, postoperative complications and multiple sclerosis. MSN procedures were performed on the median nerve (n = 40) for wrist and finger flexion;musculo-cutaneus nerve (n = 38) for elbow flexion;ulnaris nerve (n = 9) for cubital deviation of the hand;gastrocnemius nerve (n = 98) and soleus nerve (n = 49) for equinus foot, tibial posterior nerve (n = 45) for varus foot, and fascicles (or bundles) of the flexor digitorum for “claw” toes (n = 19). The main preoperative test to identify the responsible nerve was a neuromuscular block with local anesthesia (lidocaine or bupivacaine) injected into the site of the nerve connecting the spastic muscle. During surgery, the identified nerve was exposed and its epineurium opened. Nerve bundles were teased apart into individual rootlets and a number of rootlets cut were previously planned, according to the spasticity. Follow-up was performed for up to 10 years, with a mean period of 29 months. Results demonstrated a reduction of limb spasticity of 2 to 3 points: modified Ashworth scale (MAS). Pain and clonus were also diminished in the affected limb. In some cases, voluntary movement was once again possible. MSN is a useful alternative in those cases of focal spasticity where physiotherapy and nerve block with botulinum toxin or phenol no longer produce satisfactory results.

Effect of acupuncture on inflammatory cytokines expression of spastic cerebral palsy rats

Objective:To To investigate the effect of acupuncture on the tumor necrosis factor- α(TNF-α),interleukin-6(IL-6),C-reactive protein(CRP),nitric oxide synthase(NOS) content and muscular tension of spasticity cerebral palsy rat model.Methods:The rats with spastic cerebral palsy were randomly divided into the control group,model group and acupuncture group.After successful modeling,the muscular tension and the content of TNF- α,IL-6,CRP.NOS were measured.Results:The serum TNF- α,IL—6,CRP,NOS content were significantly decreased in the acupuncture group(P<0.05).The low and high shear viscosity of whole blood of the acupuncture group were significantly lower than the control group and the model group(P<0.05).The erythrocyte electrophoresis indexes in the acupuncture group were significantly lower than that in the model group and the control group(P<0.05).Acupuncture significantly reduced the muscular tension of spastic cerebral palsy rat and increased the active extent in the paralytie extremity(P<0.05),but it could not be restored to normal level.Compared with the control group,the difference had significant(P<0.05).Conclusions:Acupuncture treatment can inhibit the release of inflammatory cells after brain injury,then reduce immune injury,relieve muscle spasms and reduce muscular tension.

Effects of High Frequency Repetitive Transcranial Magnetic Stimulation on KCC2 Expression in Rats with Spasticity Following Spinal Cord Injury

The effect of high-frequency repetitive transcranial magnetic stimulation(r TMS) on potassium-chloride cotransporter-2(KCC2) protein expression following spinal cord injury(SCI) and the action mechanism were investigated. SCI models were established in SD rats. Five groups were set up randomly: normal control group, SCI 7-day(7 D) model group, SCI 14-day(14 D) model group, SCI-7 DrTMS group and SCI-14 DrTMS group(n=5 each). The rats in SCI rTMS groups were treated with 10 Hz rTMS from 8 th day and 15 th day after SCI respectively, once every day, 5 days every week, a total of 4 weeks. After the model establishment, motor recovery and spasticity alleviation were evaluated with BBB scale once a week till the end of treatment. Finally, different parts of tissues were dissected out for detection of variations of KCC2 protein using Western blotting and polymerase chain reaction(PCR) technique. The results showed that the BBS scores after treatment were significantly higher in SCI-7 DrTMS group than in SCI-14 DrTMS group(P<0.05). As compared with normal control groups, The KCC2 protein in SCI model groups was down-regulated after SCI, and the decrease was much more significant in SCI-14 D model group than in SCI-7 D group(P<0.05). As compared with SCI model groups, KCC2 protein in rTMS groups was up-regulated after the treatment(P<0.05). The up-regulation of KCC2 protein content and expression was more obvious in SCI-7 DrTMS group than in SCI-14 DrTMS group(P<0.05). It was concluded that 10 Hz rTMS can alleviate spasticity in rats with SCI, which might be attributed to the up-regulation of KCC2 protein. It was also suggested that the high-frequency rTMS treatment after SCI at early stage might achieve more satisfactory curative effectiveness.

Selective dorsal rhizotomy in cerebral palsy spasticity-a newly established operative technique in Slovenia: A case report and review of literature

BACKGROUND Spasticity affects a large number of children,mainly in the setting of cerebral palsy,however,only a few paediatric neurosurgeons deal with this problem.This is mainly due to the fact that until 1979,when Fasano has published the first series of selective dorsal rhizotomy(SDR),neurosurgeons were able to provide such children only a modest help.The therapy of spasticity has made a great progress since then.Today,peroral drugs,intramuscular and intrathecal medicines are available,that may limit the effects of the disease.In addition,surgical treatment is gaining importance,appearing in the form of deep brain stimulation,peripheral nerve procedures and SDR.All these options offer the affected children good opportunities of improving the quality of life.CASE SUMMARY A 15-year old boy is presented that was surgically treated for spasticity as a result of cerebral palsy.Laminotomy at L1 level was performed and L1 to S1 nerve roots were isolated and divided in smaller fascicles.Then,the SDR was made.CONCLUSION We describe a patient report and surgical technique of SDR that was performed in Slovenia for the first time.

Rescue axonal defects by targeting mitochondrial dynamics in hereditary spastic paraplegias

Impaired axonal development and degeneration underlie debilitating neurodegenerative diseases including hereditary spastic paraplegia, a large group of inherited diseases. Hereditary spastic paraplegia is caused by retrograde degeneration of the long corticospinal tract axons, leading to progressive spasticity and weakness of leg and hip muscles. There are over 70 subtypes with various underlying pathophysiological processes, such as defective vesicular trafficking, lipid metabolism, organelle shaping, axonal transport, and mitochondrial dysfunction. Although hereditary spastic paraplegia consists of various subtypes with different pathological characteristics, defects in mitochondrial morphology and function emerge as one of the common cellular themes in hereditary spastic paraplegia. Mitochondrial morphology and function are remodeled by mitochondrial dynamics regulated by several key fission and fusion mediators. However, the role of mitochondrial dynamics in axonal defects of hereditary spastic paraplegia remains largely unknown. Recently, studies reported perturbed mitochondrial morphology in hereditary spastic paraplegia neurons. Moreover, downregulation of mitochondrial fission regulator dynamin-related protein 1, both pharmacologically and genetically, could rescue axonal outgrowth defects in hereditary spastic paraplegia neurons, providing a potential therapeutic target for treating these hereditary spastic paraplegia. This mini-review will describe the regulation of mitochondrial fission/fusion, the link between mitochondrial dynamics and axonal defects, and the recent progress on the role of mitochondrial dynamics in axonal defects of hereditary spastic paraplegia.

Novel frameshift mutation in the SACS gene causing spastic ataxia of charlevoix-saguenay in a consanguineous family from the Arabian Peninsula:A case report and review of literature

BACKGROUND Familial cases of autosomal recessive spastic ataxia of charlevoix-saguenay have not been reported in the Arabian Peninsula,although the consanguineous marriage rate is very high.We report the first family from the Arabian Peninsula harboring a novel frameshift mutation in the SACS gene.CASE SUMMARY A 33-year-old man presented to our neurology clinic with balance problems and weakness of distal upper and lower limbs.He was previously clinically diagnosed with Friedreich's ataxia.However,the severity of polyneuropathy and the electrodiagnostic studies(EDX)findings are atypical features of Friedreich’s ataxia,and the deterioration was attributed to diabetic neuropathy.Close examination of other family members identified cerebellar ataxia,lower-limb pyramidal signs,peripheral neuropathy,and magnetic resonance imaging findings characterized by pontine linear hypointensities.Genetic testing for Friedreich’s ataxia did not yield a diagnosis.Whole exome sequencing identified a novel frameshift germline mutation in the SACS gene termed c.5824_5827delTACT using the transcript NM_014363.5,which is predicted to cause premature termination of the sacsin protein at amino acid position 1942(p.Tyr1942Metfs*9)and disrupts the sacsin SRR3 and domains downstream from it.The mutation segregated with the disease in the family.CONCLUSION Our data add to the spectrum of mutations in the SACS gene and argues for a need to implement suitably integrated clinical and diagnostic services,including next generation sequencing technology,to better classify ataxia in this area of the world.

A Randomised Controlled Study to Investigate Effects of Bobath Based Trunk Control Training on Motor Function of Children with Spastic Bilateral Cerebral Palsy

Purpose: The aim of this study was to investigate the effects of trunk control on motor function, which plays an important role in the daily activities of children with Cerebral Palsy (CP) and is often observed as a deficiency in children with CP. Material and Methods: Forty children with spastic bilateral CP, ages between 3 to 10 years and with Gross Motor Function Classification System (GMFCS) level I, II, and III were included in this study. Children were divided into two groups using randomization and in training group;Bobath Therapy for trunk control in addition to classical physiotherapy programs was performed for 45 minutes, for two days a week, for 6 weeks. In control group, existing physiotherapy program, 45 minutes for two days a week, continued. Any addition was not made into the existing program of the control group. Modified Ashworth Scale (MAS), Pediatric Berg Balance Scale (PBBS), Trunk Control Measurement Scale (TCMS), 1 Minute Walking Test (1MWT), Timed Up and Go Test (TUG) were applied to both groups before and after 6 weeks. Moreover, trunk muscle strength of children was evaluated. Results: After therapy, differences were found in results of MAS and PBBS, and trunk extensor strength between the training group and the control group in favor of the training group (p Conclusion: This study shows that adding exercises which aim trunk to conventional physiotherapy and exercise programs of children with CP, affects motor function positively.

Novel ATL1 mutation in a Chinese family with hereditary spastic paraplegia: A case report and review of literature

BACKGROUND Hereditary spastic paraplegias (HSPs) refer to a group of heterogeneous neurodegenerative diseases characterized by lower limbs spasticity and weakness. So far, over 72 genes have been found to cause HSP (SPG1-SPG72). Among autosomal dominant HSP patients, spastic paraplegia 4 (SPG4/SPAST) gene is the most common pathogenic gene, and atlastin-1 (ATL1) is the second most common one. Here we reported a novel ATL1 mutation in a Chinese spastic paraplegia 3A (SPG3A) family, which expands the clinical and genetic spectrum of ATL1 mutations. CASE SUMMARY A 9-year-old boy with progressive spastic paraplegia accompanied by right hearing loss and mental retardation for five years was admitted to our hospital.Past history was unremarkable. The family history was positive, and his grandfather and mother had similar symptoms. Neurological examinations revealed hypermyotonia in his lower limbs, hyperreflexia in knee reflex, bilateral positive Babinski signs and scissors gait. The results of blood routine test, liver function test, blood glucose test, ceruloplasmin test and vitamin test were all normal. The serum lactic acid level was significantly increased. The testing for brainstem auditory evoked potential demonstrated that the right side hearing was impaired while the left was normal. Magnetic resonance imaging showed mild atrophy of the spinal cord. The gene panel test revealed that the proband carried an ATL1 c.752A>G p.Gln251Arg (p.Q251R) mutation, and Sanger sequencing confirmed the existence of family co-segregation. CONCLUSION We reported a novel ATL1 Q251R mutation and a novel clinical phenotype of hearing loss in a Chinese SPG3A family.

Different frequencies of repetitive transcranial magnetic stimulation combined with local injection of botulinum toxin type A for post-stroke lower limb spasticity:study protocol for a prospective,single-center,non-randomized,controlled clinical trial

No definite consensus has currently been reached regarding the safety and efficacy of low-or high-frequency repetitive transcranial magnetic stimulation in the treatment of post-stroke muscle spasticity.The latest research indicates that when combined with local injections of botulinum toxin type A,it is more effective on post-stroke muscle spasticity than local injections of botulinum toxin type A alone.We designed a prospective,single-center,non-randomized,controlled clinical trial to investigate the safety and effica cy of different frequencies of repetitive transcranial magnetic stimulation combined with local injections of botulinum toxin type A in treating post-stroke lower limb muscle spasticity to determine an optimal therapeutic regimen.This trial will enroll 150 patients with post-stroke muscle spasticity admitted to the Department of Rehabilitation Medicine at the First Affiliated Hos pital of China Medical Unive rsity.All enrolled patients will undergo ro utine rehabilitation training and will be divided into five groups in-30 per group) according to the particular area of cerebral infa rction and treatment methods.G roup A:Patients with massive cerebral infarction will be given local injections of botulinum toxin type A and low-frequency(1 Hz)repetitive transcranial magnetic stimulation on the contralate ral side;G roup B:Patients with non-massive cerebral infarction will be given local injections of botulinum toxin type A and high-frequency(10-20 Hz) re petitive transcranial magnetic stimulation on the affected side;G roup C:Patients with massive/non-massive cerebral infarction will be given local injections of botulinum toxin type A;G roup D:Patients with massive cerebral infarction will be given low-frequency(1 Hz) repetitive transcranial magnetic stimulation on the contralate ral side;and G roup E:Patients with non-massive cerebral infa rction will be given high-frequency(10-20 Hz) repetitive transcranial magnetic stimulation on the affected side.The primary outcome measure of this trial is a modified Ashwo rth scale score from 1 day before treatment to 12 months after treatment.Secondary outcome measures include Fugl-M eyer Assessment of Lower Extremity,Visual Analogue Scale,modified Barthel index,and Berg Balance Scale scores for the same time as specified for primary outcome measures.The safety indicator is the incidence of adverse events at 3-12 months after treatment.We hope to draw a definite conclusion on whether there are diffe rences in the safety and efficacy of low-or high-frequency repetitive transcranial magnetic stimulation combined with botulinum toxin type A injections in the treatment of patients with post-stroke lower limb spasticity under strict grouping and standardized operation,thereby screening out the optimal therapeutic regimen.The study protocol was approved by the Medical Ethics Committee of the First Affiliated Hospital of China Medical University(approval No.[2021] 2021-333-3) on August 19,2021.The trial was registe red with the Chinese Clinical Trial Registry(Registration No.ChiCTR2100052180) on October 21,2021.The protocol version is 1.1.

Botulinum toxin injection for Cockayne syndrome with muscle spasticity over bilateral lower limbs:A case report

BACKGROUND Cockayne syndrome(CS)is a rare inherited disease characterized by progressive motor symptoms including muscle weakness,joint contracture,ataxia,and spasticity.Botulinum neurotoxin type A has been used for conditions such as dystonia and spasticity,but it has rarely been used in patients with CS.CASE SUMMARY We report a 6-year-and-9-mo old girl diagnosed with CS who received an injection of botulinum neurotoxin type A to manage her difficulty with walking.A total dose of 210 units of botulinum neurotoxin type A was administered into the bilateral tibialis posterior and gastrocnemius muscles.To evaluate the treatment effects on spasticity,joint contracture,pain,and ataxia,measurement tools including the Modified Ashworth Scale,the passive range of motion,the Faces Pain Scale-Revised,and the Scale for the Assessment and Rating of Ataxia,were employed.The first week after the injection,the Modified Ashworth Scale score for the plantar flexors and foot invertors improved bilaterally,along with advancements in the passive range of motion of the bilateral ankles and a lower score for the Faces Pain Scale-Revised.These treatment effects persisted to the 8th week post-injection,but returned to baseline values at the 12th week post-injection,except for the pain scale.CONCLUSION Botulinum toxin injection can thus be considered as a treatment option for lower extremity spasticity,joint contracture,and pain derived from CS.

Inter- and Intra-Rater Reliability of the Australian Spasticity Assessment Scale in Adults with Acquired Brain Injury

Objective: This study investigated the inter- and intra-rater reliability of the Australian Spasticity Assessment Scale (ASAS) in adults with unilateral hypertonia following acquired brain injury. The ASAS has been shown to be superior to other clinical tools for the assessment of spasticity in children with cerebral palsy but reliability has not been previously examined in adults. Method: Four muscle groups were rated on one occasion by four assessors using the ASAS in sixteen adults with unilateral hypertonia following acquired brain injury. Twelve participants returned one week later for reassessment by the same assessors. Results: Overall inter-rater reliability of the ASAS using a quadratic weighted Kappa was moderate (Kqw 0.58) with ranges from moderate to good (Kqw 0.42 - 0.70). Agreement between raters was greatest for soleus muscle and least for wrist flexors. Overall intra-rater reliability of each of the four raters was moderate to good (Kqw 0.48 - 0.79). Agreement within raters was greatest for soleus muscle and least for biceps muscle. Conclusions: The ASAS may represent an appropriate alternative to the clinical scales currently used to assess spasticity;however inter and intra-rater reliability data from this investigation are lower than those which have previously been reported by experienced users of the ASAS in children with cerebral palsy. Further investigation with a larger sample size is warranted before any firm conclusions may be drawn about the reliability and validity of this tool to assess spasticity in adults with acquired brain injury.

Co-expression of HBZ,TAX and FOXp3 and HTLV-1-associated myelopathy/tropical spastic paraparesis development in HTLV-1-infected individuals:A systematic review

Human T-cell lymphotropic virus type 1(HTLV-1)is associated with the development of HTLV-1-associated myelopathy/tropical spastic paraparesis(HAM/TSP).It has been reported that the HTLV-1 proteins(specifically TAX and HBZ)can modulate FOXp3,resulting in an immune imbalance that can favor the progression of HAM/TSP.This review aims to summarize the literature in order to clarify the relationship between the expression of HTLV-1 m RNAs and/or viral proteins(TAX and HBZ)with the expression of mRNA and/or protein FOXp3 and their correlation with HAM/TSP development.This systematic review was conducted according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis.The search strategy was performed on the Medical Literature Analysis and Retrieval System Online and Latin American and Caribbean Literature in Health Sciences Platform using subject descriptors.After screening,six articles were included in this review.The studies suggested that TAX and HBZ have a directly proportional correlation with FOXp3 in individuals with HAM/TSP,which also presented an increased expression of FOXp3 compared to asymptomatic controls and/or healthy donors.This systematic review indicates that TAX and HBZ can interact with FOXp3 and that interaction may influence HAM/TSP development.

Effect of Calcium Consumption on the Spasticity in the Spastic Rats

Spasticity is a stiff muscle condition because the muscles receive impulses continuously. Calcium ions play a role in the ability of nerves to stimulate muscle contraction. This study aimed to analyze the effect of calcium consumption on the changes of spasticity and the relation of calcium levels in the blood and muscle to the spasticity. The experimental study was conducted on 42 male Sprague-Dawley rats aged 12 - 14 weeks. The 15-d intervention was conducted on six groups of spastic rats by administering 20 g of feed containing 50 mg, 100 mg, and 200 mg of calcium, it also received 100 mg, 200 mg, and 300 mg of calcium lactate supplementation. The experimental rats were induced with 80 mg/kg BW of Erythrocin B through the tail vein to make them spastic. This study showed a tendency of increased spasticity along with the increased dose of calcium given to the subjects. There were significant differences (p = 0.007) in changes in spasticity between groups. The significant differences (p = 0.02) in changes in blood calcium levels. The Spearman’s correlations test on the changes in blood calcium levels and changes in spasticity showed a positive coefficient correlation (r = 0.097) with a p-value of 0.54. An increase in blood calcium levels and a large decrease in spasticity were found in the group receiving 100 mg calcium intake in 20 g of feed. The calcium levels in muscles had a significant correlation with spasticity (p = 0.038, r = 0.810). The calcium levels in the muscle had a strong correlation with blood calcium levels (p = 0.041, r = 0.748). The biggest decrease in spasticity occurred after 100 mg of calcium were given to the rats for 15 days, and it was considered as an optimal dose. The calcium levels in the muscles had a strong correlation with blood calcium levels and the spasticity of the spastic rats.
