Various factors have been shown to affect the rehabilitation outcome of hip fractured patients. Considering the decrease in muscle mass with aging and its impact on mobility, we hypothesized that a relationship exists between hand grip strength and rehabilitation outcome.
We retrospectively studied 373 post-hip fracture patients, admitted for rehabilitation. Muscle strength was measured by hand grip dynamometer.
functional independence measure motor functional independence measure, motor functional independence measure effectiveness and length of stay). A favorable functional gain was defined as a motor Functional Independence Measure effectiveness score > 0.5. The Spearman correlation assessed the associations between hand grip strength and outcome measures. A multiple linear regression model tested whether hand grip strength was an independent predictor of discharge motor Functional Independence Measure scores and length of stay RESULTS: Significant correlations were found between hand grip strength and functional outcomes. A significant independent association was found between hand grip strength and discharge motor Functional Independence Measure score after adjustment for confounding demographic and clinical variables. High hand grip strength on admission was significantly associated with a greater chance of achieving a favorable functional gain (OR 1.064, 95% CI, 1.01-1.13; p = 0.032). Hand grip strength was not found to be associated with length of stay.
Hand grip strength is independently associated with rehabilitation outcome in post-acute frail hip fractured patients. Initial screening for hand grip strength on admission may help identify patients who require an intensive resistance exercise program.
多种因素已被证明会影响髋部骨折患者的康复结果。考虑到肌肉质量随年龄增长而减少及其对活动能力的影响，我们假设手握力与康复结果之间存在关系。
我们回顾性研究了 373 名髋部骨折后接受康复治疗的患者。肌肉力量通过握力计进行测量。
功能独立性测量（motor functional independence measure，MFI）、MFI 有效性和住院时间。功能获得良好定义为 MFI 有效性评分>0.5。Spearman 相关分析评估了手握力与结局测量之间的相关性。多元线性回归模型测试了手握力是否是出院时 MFI 运动功能评分和住院时间的独立预测因素。
手握力与功能结果之间存在显著相关性。在手握力和出院时 MFI 评分之间发现了显著的独立关联，调整了混杂的人口统计学和临床变量。入院时高握力与实现良好功能增益的机会显著增加相关（优势比 1.064，95%可信区间，1.01-1.13；p=0.032）。握力与住院时间无关。
手握力与髋部骨折后衰弱患者的康复结果独立相关。入院时对手握力进行初步筛查可能有助于识别需要强化抗阻运动计划的患者。
