PPAM — Pneumatic Post Amputation Mobility Aid is an inflatable device (not a prosthesis) that is used in the UK by physiotherapists as part of the rehabilitation program prior to prosthetic rehabilitation.

Patella — Kneecap

Peripheral vascular disease — Disease of the blood vessels from a variety of causes

Phantom pain — Painful feeling in the part of the extremity that has been amputated

Phantom sensation — Awareness of the amputated limb, although not described as pain
