  • Degree of amputation, function, and quality of life for each participant (patients 1–9). Participants' results are ordered according limb loss degree (body maps). Functional ability was measured with the AMPS.6 The AMPS assesses the quality of performance of activities of daily living. Participants choose and perform 2 everyday tasks; results are adjusted for the difficulty of the task. Blue bars show motor scores (participants' ability to move themselves and the task objects). Purple bars show process or cognitive scores (how participants organize, sequence, and adapt to problems during the tasks). Quality of life was measured with Short Form-36 (>16 years of age) or the Child Health Questionnaire.7 Green bars show physical scores and blue bars mental/psychosocial summary scores. AMPS and Short Form-36/Child Health Questionnaire results are presented as z scores (number of SDs from the mean for age and gender).
