Summary
This study presents an algorithm to select transfer support equipment based on user physical ability. It found that railings benefit those with weak ankle joints, while seats aid those with weak knee joints.
Area of Science:
- Rehabilitation Engineering
- Biomechanics
- Assistive Technology
Background:
- Assistive robots are underutilized due to a lack of user-specific equipment selection guidance.
- Transfer support devices are crucial for mobility but require personalized matching to user capabilities.
Purpose of the Study:
- To develop an algorithm for selecting transfer support equipment tailored to individual physical abilities.
- To analyze the relationship between human body features and physical strain during standing transfers.
Main Methods:
- Investigated the link between standing support equipment and physical burdens during standing.
- Experimentally calculated and analyzed knee and ankle joint moments.
- Correlated equipment use with joint moments to assess effectiveness.
Main Results:
- Identified distinct relationships between standing support equipment and user physical ability.
- Demonstrated that railings are effective for individuals with low ankle joint residual ability.
- Showed that up/down seats are beneficial for individuals with low knee joint residual ability.
Conclusions:
- The proposed algorithm effectively matches transfer support equipment to user's physical capacity.
- Personalized selection of assistive devices like railings and seats can optimize user support and reduce physical burden.
