The present study was aimed at investigating the use of a treadmill for ambulation training of paraplegic subjects. To investigate the likely effectiveness of this modality of rehabilitation, six paraplegic patients (three male and three female) were studied, using new generation reciprocating gait orthoses (RGO and ARGO), in a treadmill training program. Oxygen consumption, heart rate, and pulmonary ventilation were measured when the subjects were walking at their most comfortable speed on the treadmill and on the open field. These measurements were carried out at the beginning of the study and after two and six months of treadmill training. The following findings were significantthe treadmill walking required 30% less energy than open field ambulation prior to training (P < 0.001) and 50% after training (P < 0.05). The most comfortable walking speed was faster on the treadmill than on the open field by 18% prior to training (P < 0.05) and 42% afterwards (P < 0.05). The energy cost was 50% less after 2 months training on the treadmill (P < 0.05) showing that treadmill training can improve the efficiency of over ground ambulation. It can be concluded that the treadmill training improves the RGO/ARGO walking capability, probably both the walking efficiency (short term adaptation) and physical fitness (long term adaptation).

本研究旨在研究跑步机用于截瘫受试者的步行训练。为了研究这种康复方式的可能有效性,在跑步机训练计划中使用新一代往复式步态矫形器 (RGO和ARGO) 研究了六名截瘫患者 (三名男性和三名女性)。当受试者以最舒适的速度在跑步机和开阔的场地上行走时,测量耗氧量,心率和肺通气。这些测量是在研究开始时以及经过两到六个月的跑步机训练后进行的。以下发现是显着的跑步机步行所需的能量比训练前 (P < 0.001) 和训练后50% (P < 0.05) 的野外步行所需的能量少30%。在跑步机上,最舒适的步行速度比在露天场地上的速度快,在训练前18% (P <0.05),之后42% (P <0.05)。在跑步机上进行2个月的训练后,能量消耗50% 较低 (P <0.05),表明跑步机训练可以提高地面移动的效率。可以得出结论,跑步机训练提高了RGO/ARGO步行能力,可能同时提高了步行效率 (短期适应) 和身体素质 (长期适应)。
