The effect of hot intermittent cupping on pain,stiffness and disability of patients with knee osteoarthritis

Objective:The aim of this study was to investigate the effect of hot intermittent cupping on pain,stiffness and inability of patients with knee osteoarthritis(KO).Methods:The present study was a clinical trial,which was performed on 38 patients with KO referring to Gonabad Rheumatology Specialty Clinic.Based on permutation block method,the research units were divided into cupping therapy and control groups.For the cupping therapy group,four sessions of cupping therapy were performed every four days.To collect data,the form of demographic information,Visual Analogue Scale(VAS)and the Western Ontario and McMaster(WOMAC)osteoarthritis scale were used,and the data were analyzed by SPSS software v.16 using descriptive statistics and independent t-test,paired t-test,Chi-square test and Fishers exact test with a significance level of P<0.05.Results:Findings showed that there was no significant difference between the cupping therapy and control groups in terms of demographic characteristics and they were homogeneous.Findings indicated that,based on VAS,the mean pain intensity in the left(P<0.001)and the right knees(P<0.001),as well as based on WOMAC,stiffness(P=0.006),pain intensity(P<0.001)and disability(P<0.001)in the cupping therapy group significantly decreased compared to the control group.Conclusion:Findings showed that hot intermittent cupping therapy reduced the pain intensity,stiffness and disability in patients with KO.

Communicating with the non-dominant hemisphere:Implications for neurological rehabilitation

Aphasic syndromes usually result from injuries to the dominant hemisphere of the brain. Despite the fact that localization of language functions shows little interindividual variability, several brain areas are simultaneously activated when language tasks are undertaken. Mechanisms of language recovery after brain injury to the dominant hemisphere seem to be relatively stereotyped, including activations of perilesional areas in the acute phase and of homologues of language areas in the non-dominant hemisphere in the subacute phase, later returning to dominant hemisphere activation in the chronic phase. Plasticity mechanisms reopen the critical period of language development, more specifically in what leads to disinhibition of the non-dominant hemisphere when brain lesions affect the dominant hemisphere. The non-dominant hemisphere plays an important role during recovery from aphasia, but currently available rehabilitation therapies have shown limited results for efficient language improvement. Large-scale randomized controlled trials that evaluate well-defined interventions in patients with aphasia are needed for stimulation of neuroplasticity mechanisms that enhance the role of the non-dominant hemisphere for language recovery. Ineffective treatment approaches should be replaced by more promising ones and the latter should be evaluated for proper application. The data generated by such studies could substantiate evidence-based rehabilitation strategies for patients with aphasia.
