The Link between Psychomotor Disorders and Physical Therapy

The evolution of the individual in ontogenesis has been studied throughout life and on all sides of development. Studies in the field based on medical rehability performed by a full team such as doctors, physiotherapists and psychologists and not only have shown that the link between the patient’s psychological state and exercise are factors in full dependence and any imbalance can trigger irreparable effects. Psychology is the science that studies the laws of formation, development, functioning and deficiencies related to psychism;it includes a series of fundamental concepts that include: psychic processes, psychic phenomena, psychic attributes, psychic states or psychic activities. Psychic phenomena are the component elements of psychism. In a sense, the psychic phenomena are manifested by external facts, by our behavior, by the motor actions started, by gestures or verbal actions;in the other sense, psychic phenomena are manifested by inner deeds, as the form of ideas, images, feelings, and desires. The motor acts without psychism would be only simple automatisms, without human specifications of adaptation, while the psychism without motor acts would be deprived of the fundamentals of formation and functioning as well as of its production mechanisms. Objective: The objective of this study is to highlight the causal problems of delayed medical recovery in relation to the psychological and emotional factors. This desktop review aims to identify psychoemotional disorders in the case of subjects with operated lumbar disc herniation and aims to adapt a specialized physiotherapeutic protocol by adapting to CIF. The result of this study will be found in the percentage of socio-professional reintegration of the subjects with operated lumbar disc herniation and implicitly the increase in the quality of life. Conclusions: 1) For an effective functional recovery, a psycho-emotional balance is needed;2) A positive attitude actively influences medical rehabilitation;3) Regaining physical, cognitive and social activities depend on the degree of psycho-emotional impairment. .

Tourette syndrome associated with attention deficit hyperactivity disorder: The impact of tics and psychopharmacological treatment options

Tourette syndrome(TS) is a neurodevelopmental disorder characterized by multiple chronic motor and vocal tics beginning in childhood. Several studies describe the association between TS and attention deficit hyperactivity disorder(ADHD). Fifty percent of children diagnosed with ADHD have comorbid tic disorder. ADHD related symptoms have been reported in 35% to 90% of children with TS. Since ADHD is the most prevalent comorbid condition with TS and those with concomitant TS and ADHD present with considerable psychosocial and behavioral impairments, it is essential for clinicians to be familiar with these diagnoses and their management. This paper highlights the association between treating ADHD with stimulants and the development of tic disorders. The two cases discussed underscore the fact that children with TS may present with ADHD symptomatology prior to the appearance of any TS related symptoms. Appropriate management of TS in a patient diagnosed with ADHD can lead to quality of life improvements and a reduction in psychosocial impairments.

Review of the evidence for the management of co-morbid Tic disorders in children and adolescents with attention deficit hyperactivity disorder

Attention deficit hyperactivity disorder(ADHD) is the most common neurodevelopmental disorder in children and adolescents, with prevalence ranging between 5% and 12% in the developed countries. Tic disorders(TD) are common co-morbidities in paediatric ADHD patients with or without pharmacotherapy treatment. There has been conflicting evidence of the role of psychostimulants in either precipitating or exacerbating TDs in ADHD patients. We carried out a literature review relating to the management of TDs in children and adolescents with ADHD through a comprehensive search of MEDLINE, EMBASE, CINAHL and Cochrane databases. No quantitative synthesis(meta-analysis) was deemed appropriate. Metaanalysis of controlled trials does not support an association between new onset or worsening of tics and normal doses of psychostimulant use. Supratherapeutic doses of dextroamphetamine have been shown to exacerbate TD. Most tics are mild or moderate and respond to psychoeducation and behavioural management. Level A evidence support the use of alpha adrenergic agonists, including Clonidine and Guanfacine, reuptake noradrenenaline inhibitors(Atomoxetine) and stimulants(Methylphenidate and Dexamphetamines) for the treatment of Tics and comorbid ADHD. Priority should be given to the management of co-morbid Tourette's syndrome(TS) or severely disabling tics in children and adolescents with ADHD. Severe TDs may require antipsychotic treatment. Antipsychotics, especially Aripiprazole, are safe and effective treatment for TS or severe Tics, but they only moderately control the co-occurring ADHD symptomatology. Short vignettes of different common clinical scenarios are presented to help clinicians determine the most appropriate treatment to consider in each patient presenting with ADHD and co-morbid TDs.

Premonitory urges located in the tongue for tic disorder: Two case reports and review of literature

BACKGROUND Premonitory urges (PUs) was defined as the uncomfortable physical sensations of inner tension that can be relieved by producing movement responses. Nearly 70%-90% patients with Tourette syndrome reported experiences of PUs. CASE SUMMARY In this paper, we present two cases of young patients with PUs located in their tongue, which is very rare and easily misdiagnosed in clinical work. Both two young patients complained of an itchy tongue and cannot help biting their tongue. These two cases were worth reporting because it was rare that PUs was the initial symptom and located in the tongue. The results indicated that PUs seem to play an important role in the generation of tics. CONCLUSION Thus, PUs may be the first process, and an essential part, of the formation of tics.

Serum ferritin levels in children with attention deficit hyperactivity disorder and tic disorder

BACKGROUND Iron plays an important role in neurodevelopmental functions in the brain.Serum ferritin levels are different in children with attention deficit hyperactivity disorder and tic disorder than in healthy children.AIM To explore the current status of iron deficiency in children with neurodevelopmental disorders and its sex and age effects.METHODS A total of 1565 children with attention deficit hyperactivity disorder(ADHD),1694 children with tic disorder(TD),93 children with ASD and 1997 healthy control children were included between January 1,2020,and December 31,2021 at Beijing Children's Hospital.We describe the differences in age levels and ferritin levels between different disease groups and their sex differences.The differences between the sexes in each disease were analyzed using the t test.The incidence rate of low serum ferritin was used to describe the differences between different diseases and different age groups.A chi-square test was used to analyze the difference in the incidence of low serum ferritin between the disease group and the control group.Analysis of variance was used for comparisons between subgroups,and regression analysis was used for confounding factor control.RESULTS A total of 1565 ADHD patients aged 5-12 years were included in this study,and the average serum ferritin levels of male and female children were 36.82±20.64μg/L and 35.64±18.56μg/L,respectively.A total of 1694 TD patients aged 5-12 years were included in this study,and the average serum ferritin levels of male and female children were 35.72±20.15μg/L and 34.54±22.12μg/L,respectively.As age increased,the incidence of low serum ferritin in ADHD and TD first decreased and then increased,and 10 years old was the turning point of rising levels.The incidence of ADHD with low serum ferritin was 8.37%,the incidence of TD with low serum ferritin was 11.04%,and the incidence of the healthy control group with low serum ferritin was 8.61%,among which male children with TD accounted for 9.25%and female children with TD accounted for 11.62%.There was a significant difference among the three groups(P<0.05).In addition,there were 93 children with ASD with an average serum ferritin level of 30.99±18.11μg/L and a serum ferritin incidence of 15.05%.CONCLUSION In conclusion,low serum ferritin is not a risk factor for ADHD or TD.The incidence of low serum ferritin levels in children with ADHD and TD between 5 and 12 years old decreases first and then increases with age.

Acupuncture:a new method to treat tic disorders in children

Tic disorder is a common pediatric neurological disorder that severely affects children’s quality of life.But in fact,there is still a lack of a very effective treatment for tic disorder.Acupuncture as a flexible treatment time,treatment cycle control,easy to operate treatment method,widely used in the field of neurological disorder,widely praised by clinicians and patients.At the same time,tic disorder belongs to the category of chronic inflammatory convulsion in traditional Chinese medicine,and acupuncture has a good effect of relieving spasticity and fewer adverse reactions,which makes acupuncture have a good application prospect.Now,more and more studies about acupuncture treatment of tic disorder in children have been published.The main methods of treating tic disorder are acupuncture,electroacupuncture,scalp acupuncture and ear acupuncture.The efficacy of acupuncture alone or in combination with other drugs such as tiapride hydrochloride and haloperidol has been shown to be good.The safety of acupuncture is also commendable,and clinical trials showing that the combination of acupuncture and medication can reduce the incidence and severity of adverse drug reactions.According to the existing studies,acupuncture can promote the development and repair of the nervous system,regulate the secretion of neurotransmitters,and reduce the occurrence of local discomfort,which may be the main mechanism of acupuncture treatment of tic disorders.

Research progress of Chinese and Western Medicine on tic disorder in children

Tic disorder is one of the common neuropsychiatric disorders that affect children’s physical and mental health.If it is not tested,diagnosed and treated early,it will have a serious impact on children themselves,their families,and even the whole society.Simple western medicine treatment methods include drugs,nerve regulation,psychological and behavioral therapy,but the results are not ideal.Traditional Chinese medicine takes systematic treatment based on syndrome differentiation and it uses methods of traditional Chinese medicine,massage and acupuncture to regulate five viscera and six bowels in order to harmonized Yin and Yang.These methods make up for the deficiencies of western treatment.In recent years,the clinical treatment of children with Tic disorders involving a variety of combined therapy has achieved significant results.As a result,the rehabilitation of children with Tic disorders has been significantly improved.By consulting the available literature at home and abroad in recent years,the author elaborates the etiology,pathogenesis and treatment of tic disorder in children,in order to further guide the clinical diagnosis and treatment.
