In individuals with transtibial amputation, the distal part of the lower extremity is lost. Therefore, the knee joint is of greater importance to be able to provide physical performance. The aim of this study was to evaluate the correlation between knee joint position sense and physical functional performance in individuals with transtibial amputation.
The study included 21 subjects with transtibial amputation. A digital inclinometer was used to evaluate the joint position sense of the amputated side knee joint. The timed up and go test, the 4-square step test, and 10-m walk test were used to evaluate physical functional performance. Linear regression analysis was used to investigate the associations between independent variables and functional performance tests.
The mean age of the participants was 52.52 ± 15.68 years. The mean of the error in knee joint position sense was 5.33 degree (standard deviation = 3.08 degree). The error in knee joint position sense of the amputated limb predicted 45% of the variance in the 4-square step test and 22% of the variance in the 10-m walk test ( P < 0.05).
The knee joint position sense on the amputated side was found to be associated with physical functional performance in individuals with transtibial amputation. Residual limb knee joint position sense should be considered when prescribing prostheses and planning rehabilitation programs.
在经胫截肢患者中，下肢远端部分缺失。因此，膝关节对于提供身体运动能力更为重要。本研究的目的是评估经胫截肢患者膝关节位置觉与身体功能表现之间的相关性。
本研究纳入了21名经胫截肢患者。使用数字倾角仪评估截肢侧膝关节的关节位置觉。采用计时起立行走测试、四方步测试和10米步行测试来评估身体功能表现。使用线性回归分析来研究自变量与功能表现测试之间的关联。
参与者的平均年龄为52.52±15.68岁。膝关节位置觉误差的平均值为5.33度（标准差=3.08度）。截肢肢体的膝关节位置觉误差预测了四方步测试中45%的方差和10米步行测试中22%的方差（P<0.05）。
发现截肢侧的膝关节位置觉与经胫截肢患者的身体功能表现相关。在开具假肢处方和规划康复方案时，应考虑残肢膝关节位置觉。
