Objective: To evaluate the transfer strategy of paraplegic subjects from their wheelchairs. Methods: Twelve thoracic spinal cord injured subjects participated in this study (T2 to T12). The subjects were able to independently transfer from a wheelchair to a one square meter (m2) platform, half a meter in height. Images of reflexive anatomic markers were captured by six ProReflex infrared cameras and processed using a QTRac Capture software. Kinematic parameters of the trunk, head, shoulders and elbows were evaluated. Results: The data analyzed compared the subjects' preferential side for performing transfers, according to the functions performed by each body segment. Angular displacement of the head on sagittal plan (y-z), and the shoulders on the transversal plan (x-y), showed statistical differences (p<0.05). Conclusion: The data obtained on this study showed that there are differences in transfer strategies of paraplegic subjects to their preferential side, in comparison with the non-preferential side. Level of Evidence II, Development of diagnostic criteria on consecutive patients (with universally applied reference "gold" standard).
Background: This study aimed to describe the effects of a 90-minute group-based constraint-induced movement therapy protocol (CIMT) on upper extremity (UE) rehabilitation in poststroke patients. Method: The study was a case series clinical study with 6 patients with chronic stroke admitted to the institutional integrated clinic. Ten 90-minute CIMT sessions were administered, based on the principles of the original therapy. On completion of the protocol, participants underwent group care once a week, for 1 hour a day. For comparison purposes, the Wolf Motor Function Test (WMFT), Motor Activity Log (MAL), and Canadian Occupational Performance Measure (COPM) were applied on admission, shortly after completing the protocol, and 3 months after completion. In addition, the MAL and shaping tasks were applied daily. Results: There was a statistically significant difference only in the MAL Amount of Use Scale applied daily between the 2nd (3.56) and 9th (3.31) and 2nd and 10th days (4.49) (P = .004), with a moderate effect size (d’ = 0.46), and in the average value of shaping repetitions between the 1st (16.10) and 2nd (6.00) and 1st and 10th tasks (7.00) (P = .014), with a moderate effect size (d’ = 0.35). Conclusion: The 90-minute CIMT protocol resulted in significant improvements in use of the more affected arm in activities of daily living during the 2-week protocol. Additional research with a larger sample and a control group is needed to confirm its effectiveness.
The loss of the ambulation capacity in individuals with Cerebrovascular Accidents (CVA) has been attributed to hemiparesis, the most frequent cause of post-CVA impairment. New approaches, such as the bodyweight supported treadmill training (BWSTT) associated with functional electrical stimulation (FES), have been suggested as a gait rehabilitation method for hemiparetic patients. Objective: The aim of the present study was to evaluate the efficacy of the BWSTT associated to FES in hemiparetic patients. Methods: Fourteen individuals with hemiparesis due to CVA were randomly selected. The Fugl-Meyer Assessment of Sensorimotor Impairment (Fugl-Meyer Scale), the Berg Balance Scale, the Functional Ambulation Category Scale and the cadence assessment were used as measurement tools. The study subjects underwent four evaluations: the first (control) carried out before and the second (pretreatment) after the conventional physical therapy, the third (post-treatment) after the BWSTT associated to FES (20 sessions) and the fourth (retention), 30 days after the end of the treatment. Results: The proposed training showed a significant improvement (p>0.05) in gait velocity, cadence, balance and motor impairment level and the results persisted 30 days after the end of the treatment. Conclusion: The BWSTT associated with FES is effective for gait rehabilitation in hemiparetic individuals.
