BACKGROUND: The study is to analyze the effectiveness of dynamic wrist splint on deltoid muscle activity using functional task practice along with strengthening exercises in post stroke patients. MATERIALS AND METHODS: Experimental study with sampling size 30 patients group A: 15 patients. Group B: 15 patients. Sampling method is convenient random sampling. Intervention period: 4 weeks. SETTINGS: Bhagwan Mahaveer Jain Hospital, Vasanthnagar, Bangalore. The patient will be received; history will be taken; explained about the treatment session and informed written consent will be taken. Patient will be made to sit comfortably. Check for safety ie, with arm rest, back rest if necessary provide cushion. Dynamic wrist splint of appropriate size will be taken; checked for fitting of the splint for any compression and avoid other complications The initial muscle activity prior to treatment will be measured using EMG for deltoid. Group A: the patient will be asked to perform a given set of activities or tasks with splint. Group B: the patient will be asked to perform a given set of activities or tasks without splint. Each session would last for 30 minutes and frequency of 3 to 4 times per week. At the end of treatment, surface EMG for deltoid is taken to check for the effectiveness of use of splint with work task during the rehabilitation program. RESULTS: After 4 weeks treatment period, the subjects in the group A were compared with the subjects in the group B. Group B had shown a significant difference with outcome measures when compared to group A CONCLUSION: It is evident from the results that the subjects who used the thumb abduction supinator splint showed significant level of improvement in function and increase in deltoid muscle activity when compared with subjects who did not use the splint as quantified using Fugl Meyer Scale for upper extremity and surface EMG.
