Thirteen normal male college students were studied during unassisted ambulation and nonweight-bearing ambulation with Ortho crutches and axillary crutches to determine energy expenditure. Subjects walked at self-selected velocities. Energy expenditure was determined by analyzing expired air collected by a calorimeter. Heart rate was monitored by telemetry. During the first 2.5 minutes of walking, heart rate and energy expenditure were significantly greater for ambulation with axillary crutches than with Ortho crutches. After 11.5 minutes of walking, no difference in energy cost was found between crutch types; however, heart rate increased significantly (p less than .01) during ambulation with axillary crutches. Differences in energy cost and heart rate were attributed to increased upper extremity work performed when using axillary crutches. We concluded that during nonweight-bearing ambulation for short periods of time or over a short distance, the Ortho crutch is less taxing in terms of energy cost and heart rate demands.
对13名正常男性大学生在自主行走以及使用奥索拐杖和腋拐进行非负重行走时的能量消耗情况进行了研究。受试者以自我选择的速度行走。通过分析热量计收集的呼出气体来确定能量消耗。通过遥测监测心率。在行走的前2.5分钟内，使用腋拐行走时的心率和能量消耗显著高于使用奥索拐杖行走时。行走11.5分钟后，发现不同类型拐杖之间的能量消耗没有差异；然而，使用腋拐行走时心率显著增加（p小于0.01）。能量消耗和心率的差异归因于使用腋拐时上肢工作量的增加。我们得出结论，在短时间或短距离的非负重行走中，就能量消耗和心率需求而言，奥索拐杖的负担较小。
