The purpose of this study is to conduct a retrospective chart audit of initial physical therapy evaluation to determine the incidence of sitting imbalance and its relationship to the side of weakness in hemiparetic patients. A review of the records of 36 patients revealed that the left side was predominantly affected in 17 patients and the right side in 19 patients. Ages, time since onset, and proportion of men and women did not difer between the left and right hemiparetic patients. About half patients(52.8%) could sit independently, but 64.7% of those with left-sided weak-ness and 31.6% of those with right-sided weakness could not. A chi-sequare analysis revealed a significant relationship between the side of weakness and independent sitting balance(p<0.1). Patients with left hemiplegia are more likely to have difficulty with independent sitting balance(p<0.1). Patient with left hemiplegia are more likely to have difficulty with independent sitting than patients with right hemiplegia, which may affect their progress in rehabilitation.

However, the thickness of right side of hind limb were significantly increased and the differences of thickness between both sides of hind limb were dramatically decreased in massage groups compared to that of Control group in followed order: T1 > T3 > T2. 3. Absolute and relative weight of M. gastrocnemius in the intact left side of hind limb was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. gastrocnemius were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. gastrocnemius between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. gastrocnemius were significantly increased and the differences of weight between both sides of M. gastrocnemius were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 >. 4. Absolute and relative weight of M. tibialis cranialis in the intact left side was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. tibialis cranialis were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. tibialis cranialis between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. tibialis cranialis were significantly increased and . the differences of weight between both sides of M. tibialis cranialis were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 > T2. 5. Absolute and relative weight of M. tibialis caudalis in the intact left side was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. tibialis caudalis were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. tibialis caudalis between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. tibialis caudalis were significantly increased and the differences of weight between both sides of M. tibialis caudalis were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 > T2. 6. A significant increase of serum AST levels were demonstrated in Control group. However, serum AST levels of massage groups were significantly decreased compared to that of Control group in followed order: T3 > T1 > T2. In case of 73 group, the values decreased into similar levels compared to that of Sham group. 7. A significant increase of serum CK levels were demonstrated in Control group.

Purpose: This study was conducted to investigate changes in the cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort following the wearing of a trunk brace during smartphone watching. Methods: To calculate the number of subjects for this study, an analysis with G^*Power was performed at a statistical power of 0.8, an effect size of 0.5, and a significance level of 0.05, based on the results of a preliminary experiment on five subjects. In total, 27 adult men and women were recruited who had been informed of the study's purpose and process and had agreed to participate. All subjects watched content on a smartphone for 20 minutes in the same posture and conditions while wearing and not wearing a trunk brace, and then their cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort were measured. Results: Compared to the non-wearing of a trunk brace, the wearing of a trunk brace resulted in a statistically significant smaller decline in cervical extension and right-side cervical rotation (p<0.05). When the subjects wore a trunk brace, their right- and left-side cervical and right-side lumbar pressure pain statistically significantly improved when compared to not wearing a trunk brace (p<0.05). They also perceived a significantly lowered level of comfort 20 minutes after wearing a trunk brace compared to immediately after wearing it (p<0.05). Conclusion: The trunk brace was effective in reducing declines in right-side cervical rotation and the occurrence of left- and right-side cervical and right-side lumbar pressure pain. The findings indicate the need to improve the perceived comfort of trunk braces.
