RESUMEN
AIM: The aim of this study was to analyse the evidence of effectiveness on adult stroke patients of the Constraint Induced Movement Therapy (CIMT), an original rehabilitation method that consists in strongly encouraging patients to use the affected arm, mainly immobilising the unaffected arm. METHODS: We only took into account the randomised controlled trials on CIMT where the experimental treatment was compared with a conventional treatment without any discrepancy of organization or session duration. As we could not measure the statistical significance of differences between treated and control patients, we compared their respective post-treatment percent changes and computed the minimal clinically important difference (MCID), defined as a change of at least 10% of the maximum score of the scale used. RESULTS: The literature search found 13 randomised controlled trials (RCTs), 4 of which were excluded because they aimed at comparing different intensity of CIMT. The 9 RCTs finally included into the review applied the CIMT in either acute, subacute or chronic stroke patients and according to different modalities. Findings were positive in all studies, but the MCID was reached only in smaller ones, which may have been influenced by patients' characteristics. CONCLUSION: Although all studies achieved positive results, it is impossible to draw any clear-cut conclusion on the effectiveness of the CIMT. The main limitations are the lack of homogeneity in the outcome measures used, the inadequacy of data provided and the small samples' size. Multicentre studies, using robust outcome measures and considering both motor- and sensory-disabled patients are needed.

AIM: The aim of the study was to evaluate the long-term efficacy of night-only splint wear therapy for carpal tunnel syndrome (CTS). METHODS: We conducted a randomized case-control trial with evaluation after three and six months of follow-up of outpatients with mild, recent onset symptoms of CTS recruited from the department clinic. Fifty patients (50 hands) were enrolled, of which 36 completed the study at 6 months. The case group utilized a thermoplastic neutral wrist splint for night-only wear. Outcome measures were instrumental parameters (sensory and motor nerve conduction velocity), symptom and function alterations (as measured by Levine's self-administered questionnaire), clinical parameters (pressure-provocative and Phalen tests). RESULTS: Improvements were observed in Levine's symptom status score at the three-month (P=0.001) and the six-month (P=0.001) follow-up visits, in functional score (P=0.0001) and (P=0.0004), in median distal sensory latency (P=0.01) and (P=0.02), in pressure-provocative test outcome (P=0.01) and (P=0.003), in Phalen test outcome (P=0.04) and (P=0.05) respectively. CONCLUSION: Symptom relief and neurophysiological improvement after night-only splint wear therapy lasted up to the six-month follow-up visit.
