The purpose of this paper is to present methodology specifically designed for objective study of problems associated with physiological stresses of manual wheelchair use. Excessive metabolic and cardiopulmonary stresses for everyday tasks could hinder rehabilitative efforts and be hazardous for certain patients. Sources of stress include: the relatively small musculature used for propulsion; architectural barriers; low levels of physical fitness; and inefficient wheelchair design. We propose that in order to reduce these stresses, quantitative data related to their mechanisms need to be derived. Therefore, we are conducting studies in the following areas; 1. Quantitation of metabolic, cardiovascular and pulmonary stresses of operating manual wheelchairs over various terrains; 2. Evaluation of physical fitness of wheelchair-dependent patients; 3. Improvement of physical fitness of wheelchair-dependent patients; and 4. Evaluation of the efficiency of various wheelchair designs. This research to date has provided further understanding of problems related to wheelchair confinement and demonstrated techniques to alleviate them. In this way, wheelchair locomotion could become less stressful and thus contribute to a higher level of rehabilitation.
本文的目的是介绍专门设计用于客观研究与手动轮椅使用的生理压力相关问题的方法。日常任务中过度的代谢和心肺压力可能会阻碍康复进程，对某些患者来说是危险的。压力来源包括：用于推进的相对较小的肌肉组织；建筑障碍；身体素质水平低；以及低效的轮椅设计。我们认为，为了减轻这些压力，需要获取与其机制相关的定量数据。因此，我们正在以下领域开展研究：1. 量化在各种地形上操作手动轮椅时的代谢、心血管和肺部压力；2. 评估依赖轮椅的患者的身体素质；3. 改善依赖轮椅的患者的身体素质；4. 评估各种轮椅设计的效率。迄今为止，这项研究进一步加深了对与轮椅限制相关问题的理解，并展示了缓解这些问题的技术。通过这种方式，轮椅移动可能会减轻压力，从而有助于提高康复水平。
