目的
本研究的目的是评估康复对身体能力、手动轮椅推进的机械效率以及标准化日常生活活动（ADL）表现的影响。
方法
19名最近受伤的脊髓损伤受试者进行了测试轮椅测力计（最大等长力量，冲刺和最大功率输出，峰值摄氧量）和标准化的ADL（物理应变和性能时间）在开始（t1）和结束（t2）的积极康复期。
结果
配对t检验显示，最大等长肌力（24%，P < 0.01）、短跑输出功率（17%，P < 0.001）和最大输出功率（38%，P < 0.001）显著增加。峰值摄氧量无统计学显著改善（11%，P = 0.06）。次极量轮椅运动的机械效率在t2（9.0%）显著高于t1（7.9%，P < 0.01）。除通过门时外，两组在日常生活活动中的体力负荷差异无统计学意义（P> 0.05）。大多数任务的执行时间显着减少。
结论
本研究的结果表明，在康复过程中的体力和机械效率的手动轮椅推进相当大的改善，并伴随着较低的性能时间在标准化的ADL。在标准化ADL期间，较高的机械效率和执行时间的减少表明轮椅推进技术的改善。
PURPOSE
The objective of the present study was to evaluate the effect of rehabilitation on physical capacity, mechanical efficiency of manual wheelchair propulsion, and performance of standardized activities of daily living (ADL).
METHODS
Nineteen recently injured subjects with spinal cord injuries were tested on a wheelchair ergometer (maximal isometric strength, sprint and maximal power output, and peak oxygen uptake) and during standardized ADL (physical strain and performance time) at the beginning (t1) and at the end (t2) of the active rehabilitation period.
RESULTS
Paired Student t-tests showed significant increases for maximal isometric strength (24%, P < 0.01), sprint power output (l7%, P < 0.001) and maximal power output (38%, P < 0.001). Peak oxygen uptake showed no statistically significant improvement (11%, P = 0.06). Mechanical efficiency of submaximal wheelchair exercise was significantly higher at t2 (9.0%) compared to t1 (7.9%, P < 0.01). No significant differences were found for physical strain during ADL, except for passing a door (P < 0.05). Performance time showed a significant decrease for most tasks.
CONCLUSIONS
The results of this study show considerable improvements in physical capacity and mechanical efficiency of manual wheelchair propulsion during rehabilitation, and a concomitant lower performance time during standardized ADL. The higher mechanical efficiency and the decrease in performance time during standardized ADL suggest improvement in wheelchair propulsion technique.
