Relationship between how much of the arm is missing and balance, neck/back pain, daily activities, and reaction time in people with a unilateral upper limb amputation

Official title: The Relationship Between Lost Extremity Percentage and Postural Control, Neck and Low Back Pain, Daily Living Activities, and Reaction Time in Individuals With Unilateral Upper Limb Amputation

Run by Hacettepe University · NCT07677969 · Data updated 2026-11-12

This study will see if the amount of arm loss relates to balance, neck and back pain, daily tasks, hand dexterity, and reaction time in adults who use a myoelectric or bionic prosthesis.

Is this trial a fit for you?

Likely a good fit

Adults 18–65 with unilateral upper limb amputation using a myoelectric or bionic prosthesis for at least 3 months.

Probably not a fit

Individuals with bilateral amputations, non‑prosthesis users, or those with confounding neurological or orthopedic conditions may not experience direct benefit.

What this trial studies

This observational study analyzes how the percentage of unilateral upper limb amputation relates to functional outcomes such as postural control, pain, daily living activities, hand dexterity, and reaction time. Participants aged 18–65 who wear a myoelectric or bionic prosthesis for at least a year will undergo non‑invasive assessments in a single session, including force‑platform postural measurements, posture analysis, pain rating, a daily activities questionnaire, the Box and Block Test for dexterity, and a reaction‑time task. No interventions or treatments are given; results will describe associations rather than cause and effect. The study is conducted at Hacettepe University in Ankara, under the lead sponsor and with no listed collaborators.

Why it matters

Potential benefit: If relationships are identified, results could inform rehabilitation approaches and prosthesis design to improve balance, pain management, and daily functioning.

How similar studies have gone: Limited prior research has explored how the extent of limb loss influences these outcomes, making this study relatively novel in its specific focus.
