Abstract
Background: Prosthetic limbs often lack the innate control and sensory feedback capabilities of natural limbs, requiring more cognitive effort or attention during motor tasks. While a conceptual model of prosthetic attention exists for lower limb (LL) users, its applicability to upper limb (UL) remains unclear. This study aimed to explore how LL and UL users experience prosthetic attention, and explore factors that influence the existing model.
Methods: Twenty five UL users and thirty LL users with at or above wrist or ankle-level limb loss participated. Focus groups (FG), guided by open-ended questions, delved into user’s lived experiences with prosthetic attention. Qualitative analysis identified situations and activities requiring attention to the prosthesis.
Results: Findings from 11 FGs were attention-driving stimuli, individual factors (modifiable and unmodifiable) that influence attention, and consequences of paying attention to the prosthesis for both LL and UL users. LL users cited terrain and space constraints, while UL users mentioned type of tasks (fine or gross motor, unimanual or bimanual) as reasons for attention. Both groups noted modifiable individual factors like self-image and self-efficacy, alongside unmodifiable demographic factors such as level of limb loss. LL group prioritized fall prevention as a desired result of attention, whereas UL group emphasized avoiding damaging objects or spilling.
Conclusion: The initial framework seems applicable to both UL and LL groups, revealing similarities in individual factors affecting prosthetic attention. However, differences emerged regarding attention stimuli and outcomes. Understanding heightened cognitive demands can aid clinicians in devising targeted rehabilitation plans to enhance prosthetic utilization.
