Relationship between characteristics of segmental phase angles and walking ability in patients with hemiplegia after stroke and traumatic brain injury in a convalescent rehabilitation ward
研究了恢复期康复病房中脑卒中和创伤性脑损伤偏瘫患者入院时躯干、患侧和健侧肢体的相位角特征，发现只有躯干相位角与出院时步行能力显著相关。
This study determined the characteristics of the phase angles (PhAs) of the trunk, affected limb, and unaffected limb at admission and their relationship with walking ability at discharge in patients with stroke and traumatic brain injury in a convalescent rehabilitation ward. Stroke and traumatic brain injury survivors with hemiplegia admitted to a convalescent rehabilitation ward were divided into independent- and dependent-walking groups. The trunk, affected limb, and unaffected limb PhAs were evaluated using bioelectrical impedance analysis and compared between the independent- and dependent-walking groups. Friedman's test was performed to analyze differences in the trunk, affected limb, and unaffected limb PhAs within each group. Multiple regression was performed to examine the association between walking ability and segmental PhAs. We enrolled 47 patients (independent-walking group: n = 12; dependent-walking group: n = 35). The dependent-walking group had a significantly lower trunk, affected limb, and unaffected limb PhAs. The segmental PhA was higher in the trunk than in the affected and unaffected limbs in the independent-walking group and lower in the affected limb than in the trunk and unaffected limb in the dependent-walking group. Only the trunk PhA at admission was significantly associated with walking ability at discharge ( β = 0.367; P = 0.002). The trunk PhA at admission may be related to walking ability at discharge in patients undergoing stroke and traumatic brain injury rehabilitation.
