Relationship between body acceleration and muscle load of upper limbs in lower-limb amputees during ladder climbing

摘要

In recent years, the popularity of sports climbing competitions has increased. Currently, not only able-bodied people but also people with disabilities may be interested in sports climbing. However, evaluation and guidance in climbing competitions are subjective, and those who attempt sports climbing for the first time may find it difficult to compete. Additionally, the current training methods have been developed for able-bodied people, and it is not known whether they are suitable for people with disabilities. If an objective evaluation method is established, it will be possible to propose a rational and effective teaching method for sports climbing participants. Therefore, the ultimate goal of this study is to develop an objective training method for climbing for lower-leg amputees. We studied subjects climbing a ladder that imitated the wall-climbing process and analyzed the relationship between EMG of the upper limbs and body center acceleration during climbing, which revealed a close relationship.
