Prosthetic Limbs: Design | Everyday Life
Prosthetic Limbs & Everyday Life
How prostheses support movement and daily life, and why a comfortable fit matters.
What is a prosthetic limb?
Clinical focus: A prosthetic limb is an artificial arm, hand, leg or foot. It can help a person move, carry out everyday tasks and pursue personal goals. The right device and fit depend on the person’s needs.
Lower-limb prostheses
- Replace part or all of a leg or foot.
- Transtibial means below the knee; transfemoral means above the knee.
- Components may be chosen for walking, balance or specific activities such as running.
Upper-limb prostheses
- Replace part or all of an arm or hand.
- Some are passive; others use cables moved by the body.
- Myoelectric devices use muscle signals to control movement.
Fit and rehabilitation
- A custom socket connects the prosthesis to the residual limb.
- Comfort, skin condition and control need regular review.
- A prosthetist and rehabilitation team help with fitting, adjustments and training.
Patient-centred language: Ask what the person calls their limb or device and what activities matter to them. A prosthesis can support independence, but no single design suits everyone.
Clinical note: Persistent pain, rubbing or skin damage should be discussed with the prosthetist or care team. This page is educational and does not replace individual clinical advice.
History taking: the prosthetic limb patient
Clinical focus: A careful anamnesis helps you understand not only the residual limb and prosthesis, but also how the device affects daily life, pain, skin health and the patient’s goals. Use open questions and the patient’s preferred language for their limb or device.
Key areas to explore
- Reason for the amputation and time since surgery
- Socket comfort, fit and any recent changes
- Skin condition and residual-limb care
- Pain (phantom, residual-limb, or secondary musculoskeletal pain)
- Functional goals and current limitations
- Psychosocial impact and confidence with the prosthesis
Useful open questions
- “How does the prosthesis feel at the moment?”
- “Where do you notice discomfort or rubbing?”
- “Has the fit changed recently — for example after weight change or swelling?”
- “What activities are most important for you right now?”
- “How is the skin on the residual limb?”
- “Do you experience phantom sensations or pain?”
Clinical language tips
- Ask what term the patient prefers: “residual limb”, “stump”, or their own word.
- Distinguish between phantom pain, residual-limb pain and secondary back/hip/shoulder pain.
- Note whether problems occur at donning, during use, or after prolonged wear.
- Document socket type, liner, and any recent adjustments by the prosthetist.
Sample opening: “I’d like to understand how the prosthesis is working for you day to day. Can you tell me a bit about the residual limb and how the socket feels when you walk or stand for longer periods?”
Red flags to follow up: sudden change in fit, new skin breakdown, increasing phantom or residual-limb pain, or reduced use of the prosthesis because of discomfort.
Sample dialogue
A short exchange between an osteopath and a patient with a transtibial prosthesis. Notice the open questions, clarification of terms, and attention to both the residual limb and secondary symptoms.
Osteopath: Good morning. I’d like to understand how things are going with the prosthesis. First, what term do you prefer for the residual limb?
Patient: I usually just say “my stump”. That’s fine.
Osteopath: Okay, thank you. How long have you been using this prosthesis?
Patient: About fourteen months now. I had the amputation after a road traffic accident.
Osteopath: And how does the socket feel at the moment? Any discomfort or rubbing?
Patient: It’s mostly okay in the morning, but after a few hours it starts to feel tight at the front, just below the knee. Sometimes the skin gets a bit red there.
Osteopath: Has the fit changed recently — for example after any weight change or swelling?
Patient: I’ve put on a little weight over the last couple of months. I think that might be part of it.
Osteopath: Do you get any phantom sensations or pain in the missing part of the leg?
Patient: Yes, occasionally — a sort of burning feeling in the foot that isn’t there. It’s not constant, though.
Osteopath: And what about the rest of your body? Any low-back, hip or knee pain on the other side?
Patient: My lower back gets stiff by the end of the day, especially if I’ve been standing a lot.
Osteopath: What activities matter most to you right now? What would you like to be able to do more comfortably?
Patient: I’d really like to walk longer distances without having to stop and adjust the prosthesis, and to feel more confident on uneven ground.
Teaching points from the dialogue:
- The clinician checks the patient’s preferred terminology early.
- Questions move from the prosthesis itself → residual limb → phantom phenomena → secondary musculoskeletal symptoms → functional goals.
- The patient volunteers useful clinical information (weight change, skin redness, end-of-day back stiffness).
Watch: The sore problem of prosthetic limbs
In this TED talk, David Sengeh explains why discomfort can stop people using their prostheses and how his team explored more comfortable socket designs.
While you watch: Why were some people not wearing their prostheses? How could a better socket improve daily life? What questions would you ask a patient about comfort and fit?
