Simple Explanation

This study investigates how well people accept and use exosuits, specifically the Myosuit, in their homes and communities. The research aims to understand the challenges and benefits of using such technology in unsupervised, real-world settings, rather than just in clinical environments. Seven participants, who had the Myosuit at home for at least a month, were involved in the study. They completed questionnaires, participated in interviews, and had their device usage monitored to gather both quantitative and qualitative data. The study found that while the exosuit is generally usable and well-received, its adoption in daily life is limited. Difficulties in putting on the device, leading to a lack of independence, and a lack of motivation to exercise were major factors hindering more extensive use.

Study Duration
At least 28 days
Participants
7 expert users with muscular weakness of the legs
Evidence Level
Case series, mixed-method study

Key Findings

  • 1
    The Myosuit received an above-average usability score, indicating that it is generally easy to use. Participants expressed high satisfaction with most of the technical features of the Myosuit.
  • 2
    Participants mainly used the Myosuit for walking outdoors and exercising at home. The frequency of use did not consistently meet the recommended levels for physical activity.
  • 3
    Major factors preventing extensive use were difficulties in donning the exosuit, leading to a lack of independence, and a general lack of motivation to exercise.

Research Summary

This study evaluated the usability of the Myosuit, an exosuit designed to assist individuals with lower limb motor impairments, in domestic and community environments. The research combined quantitative data from questionnaires and device sensors with qualitative data from semi-structured interviews to assess end-user perspectives and adoption of the device. The findings indicate that while the Myosuit has good usability and users are generally satisfied with its technical features, the frequency of its use in daily life is limited. Key challenges include difficulties in donning the device independently, which reduces the spontaneity and frequency of use. The study concludes that future exosuit designs should prioritize ease of donning and increased adjustability to promote independent use and greater adoption in unsupervised settings. Additionally, the study emphasizes the importance of addressing motivational factors and integrating the device into users' daily routines.

Practical Implications

Design Improvements

Exosuit designs should focus on simplifying the donning process to enable independent use by individuals with motor impairments.

Therapist Integration

Therapists should be encouraged to incorporate exosuit technology into their sessions to better educate patients on device usage and promote adherence to training.

Motivational Strategies

Exosuits could incorporate real-time feedback mechanisms to enhance user motivation and encourage more frequent and consistent use.

Study Limitations

  • 1
    Limited sample size of seven participants.
  • 2
    Potential selection bias towards participants highly interested in the technology.
  • 3
    The study did not fully explore the long-term impact of exosuit use on quality of life and secondary health conditions.
