Accurate, reliable assessment of upper extremity muscular power in persons with paraplegia caused by spinal cord injury (SCI) would provide an objective indication of their ability to generate the forces necessary for the performance of daily activities. Wingate Anaerobic Testing (WAnT) consists of a 30-second sprint test on a cycle ergometer and has been used widely in both athletic and research settings.
To examine test-retest reliability of arm WAnT performance in persons with complete SCI and paraplegia.
Forty-three participants with thoracic-level paraplegia (T2 through T12) performed 2 trials of arm WAnT with 2 to 7 days between each trial. Testing was performed using a Monarch 834E ergometer with participants seated in their wheelchairs. Participants were directed to crank at maximal pace for 30 seconds against a resistance load equivalent to 3.5% of their body mass. The SMI OptoSensor 2000 system was used to determine values of peak power (P(peak)), mean power (P(mean)), minimum power, and rate of fatigue, which were compared between trials using 1-way analysis of variance for repeated measures. Coefficients of determination (r2) were calculated between trials for P(peak) and P(mean).
No significant difference was found between trials for any of the power output variables. Regression analysis indicated that P(peak) and P(mean) were closely associated between the 2 trials (r2 = 0.92 and 0.94, respectively).
Arm WAnT is a reliable measurement tool for the assessment of upper extremity muscular power in persons with complete paraplegia.
准确、可靠地评估脊髓损伤(SCI)导致截瘫患者的上肢肌肉力量,将为他们产生日常活动所需力量的能力提供客观指标。温盖特无氧测试(WAnT)包括在自行车测力计上进行的30秒冲刺测试,已在体育和研究环境中广泛使用。
研究完全性SCI和截瘫患者手臂WAnT测试结果的重测信度。
43名胸段截瘫(T2至T12)患者进行了2次手臂WAnT测试,每次测试间隔2至7天。测试使用Monarch 834E测力计,参与者坐在轮椅上。参与者被要求以最大速度蹬踏30秒,对抗相当于其体重3.5%的阻力负荷。使用SMI OptoSensor 2000系统确定峰值功率(P(peak))、平均功率(P(mean))、最小功率和疲劳率的值,并使用重复测量的单向方差分析在各次测试之间进行比较。计算P(peak)和P(mean)在各次测试之间的决定系数(r2)。
任何功率输出变量在各次测试之间均未发现显著差异。回归分析表明,两次测试之间P(peak)和P(mean)密切相关(r2分别为0.92和0.94)。
手臂WAnT是评估完全性截瘫患者上肢肌肉力量的可靠测量工具。
