The Sway Paths of the Center of Gravity in the Static-standing Posture, Static-sitting Posture and the Voluntary Shifting-sitting Posture of Hemiparetic Stroke Patients.

A user’s posture at a computer workstation, especially wrist posture, is determined by the keyboard angle. Most commercially available computer keyboards have a built-in positive slope that requires the user to extend their wrist approximately 20° when typing. The purpose of this study is to find the negative keyboard angles that minimize wrist extension for both sitting and standing workstations. In this study, we compared upper limb working postures, including those of the wrist, elbow and shoulder, at 5 different keyboard angles between −16° and +6° in sitting and standing postures. Based on our results, we can conclude that the optimal range of keyboard slope is from −4° to −12° in sitting posture and −8° to −12° in the standing posture in terms of minimum wrist extension, typing performance, and user preference. We also propose a universal keyboard support design as an attachment to currently available keyboards.

Background of the study: Stroke is a major public health problem that ranks in the top four causes of death in most of the countries and is responsible for a large proportion of the burden of neurologic disorders. Patients with stroke have poor balance because they cannot control dynamically the size of the base of support or the location of the line of gravity. Perturbation training undergoes the maximal sway possible without losing his balance. Objective of the study: The objective of the study is to find the effects of rolling board perturbation training on balance among hemiparetic stroke patients. Methodology: Thirty clinically diagnosed hemiparetic stroke patients were selected based on the inclusion and exclusion criteria. They were randomly allocated into two groups (Group A and Group B) consists of 15 subjects each. Group A received conventional physiotherapy alone and group B received rolling board perturbation training along with conventional physiotherapy. Intervention lasted for 4 weeks, three days in a week and one hour per day. Balance was measured before and after 4 weeks of intervention by berg balance scale. Conclusion: Both conventional physiotherapy alone and rolling board perturbation training along with conventional physiotherapy significantly improved balance among hemiparetic stroke patients. When comparing both rolling board perturbation training along with conventional physiotherapy is more effective than conventional physiotherapy alone in improving balance among hemiparetic stroke patients.

Introduction Hemiparetic Stroke patients have their daily activities affected by the balance impairment. Techniques that used visual information for training this impairment it seems to be effective. Objective To analyze the effects of the unstable balance board training and compare two ways of visual feedback: the biomechanical instrumentation and the mirror. Materials and methods Eight chronic hemiparetic Stroke patients participated in the research, randomized in two groups. The first group (G1) accomplished the training with biomechanical instrumentation, and the second group (G2) trained in front of the mirror. Sixteen training sessions were done with feet together, and feet apart. The evaluation instruments that were used before and after the period of training were the Time Up and Go Test (TUGT), Berg Balance Scale (BBS) and the Instrumented Balance Board (IBB), that quantified the functional mobility, the balance and the posture control respectively. Results The TUGT showed significant results (p < 0.05) favorable to G1. Despite the results of BBS were significant for G2, the intergroup comparison did not reveal statistical significance. Both groups obtained decrease in levels of IBB oscillation, what can indicate a higher stability, however the results did not indicate statistical significance (p > 0.05). A strong correlation between all the applied tests was observed in this research. Conclusion Although the advantages found were different between the groups, in both it could be observed that the training brought benefits, with the transference to the functional mobility.
