Psychosocial Factors Influence Physical Activity after Dysvascular Amputation: A Convergent Mixed-Methods Study.

Area of Science:

• Rehabilitation Medicine
• Prosthetics and Orthotics
• Psychosocial Health

Background:

• Physical function is a key rehabilitation target for individuals with dysvascular lower-limb amputation (LLA).
• The impact of psychosocial factors on physical activity levels in this population remains unclear.
• Understanding these factors is crucial for effective rehabilitation strategies.

Purpose of the Study:

• To identify psychosocial factors influencing physical activity, physical function, and disability in individuals with dysvascular LLA.
• To explore participants' narratives to understand the lived experience of LLA.
• To provide a comprehensive view of factors affecting mobility and daily life.

Main Methods:

• Convergent mixed-methods design integrating quantitative and qualitative data.
• Participants (n=20) with dysvascular LLA, at least 1 year post-amputation, ambulating independently.
• Quantitative measures included physical activity (steps/day), physical function (Timed Up-and-Go), and disability (WHODAS 2.0); qualitative data from semistructured interviews.

Main Results:

• Higher daily steps correlated with better Timed Up-and-Go performance but not disability scores.
• Qualitative analysis revealed four key themes: prosthesis perception, fear during mobility, impact on life activities, and positive social interactions.
• Mixed-methods analysis highlighted the interplay of these psychosocial factors on physical activity.

Conclusions:

• Physical activity post-dysvascular LLA is a complex interplay of psychosocial factors.
• Interventions targeting prosthesis perception, mobility-related fear, life impact, and social engagement may enhance physical activity.
• Addressing these psychosocial elements holds potential for improving physical function and reducing disability.
