How the natural deterioration of aging, sex difference, and pathological effect of stroke affect the prediction of hand strength is still unknown.
This study aimed to compare and predict grip strength in both hands between normal controls (NCs) and stroke patients.
Observational, cross-sectional study.
Two urban hospitals and the community.
A total of 160 participants aged from 40 to 80 (80 NCs and stroke patients) were recruited.
The Jamar Plus+ Digital Hand Dynamometer was used to measure the grip strength. Stroke participants were additionally assessed by the Fugl-Meyer Assessment and Modified Ashworth Scale.
The linear regression models of the grip strength in both right and left hands were good fits (the adjusted R of 0.680-0.751) between NCs and stroke patients with either the right dominant or left non-dominant hand affected. Group (NCs versus stroke), sex, and age were sequentially the first three statistically significant predictors in the grip strength of both hands between NCs and stroke patients with either the right dominant or left non-dominant hand affected.
The pathological, sex, and age effects play complementary roles in predicting the grip strength in middle-aged and older adults between NCs and stroke patients.
In clinical practice, the recovery of the grip strength in stroke patients should take pathological, sex, and age effects together with the right dominant or left non-dominant hand affected into consideration, rather than merely comparing the differences in the grip strength of both right and left hands as a reference.
衰老的自然退化、性别差异以及中风的病理影响如何影响手部力量的预测尚不清楚。
本研究旨在比较和预测正常对照组（NCs）和中风患者双手的握力。
观察性、横断面研究。
两家城市医院和社区。
共招募了 160 名年龄在 40 岁至 80 岁之间的参与者（80 名 NCs 和中风患者）。
使用 Jamar Plus+数字握力计测量握力。中风参与者还接受了 Fugl-Meyer 评估和改良 Ashworth 量表的评估。
右侧或左侧非优势手受影响的 NCs 和中风患者之间，右手或左手优势手的握力在右利手或左非利手受影响的 NCs 和中风患者之间的线性回归模型拟合良好（调整后的 R 值为 0.680-0.751）。组（NCs 与中风）、性别和年龄是影响右利手或左非利手受影响的 NCs 和中风患者之间双手握力的前三个具有统计学意义的预测因素。
病理、性别和年龄因素在预测 NCs 和中风患者中年和老年人群的握力方面发挥着互补作用。
在临床实践中，中风患者握力的恢复应综合考虑病理、性别和年龄影响，以及右侧或左侧非优势手受影响，而不仅仅是比较双手握力的差异作为参考。
