Wellness and Self-Improvement

Key wellness / self-care & safety strategies (transfer training)

Prevent falls by setting up stable body positions

  • Scoot forward in the chair to get about halfway out into a stable starting position.
  • Place the prosthetic leg so the heel is slightly off the ground with weight mainly on the toes before rising.
  • Reach a fully locked knee extension during standing—if the knee doesn’t fully extend, the leg may buckle on the first step.

Use consistent hand/weight placement

During sit-to-stand:

  • One hand on the chair
  • One hand up on the walker
  • Lean forward over the toes and press down through the prosthetic side to stand.

During standing-to-sitting:

  • Reposition back to the chair until the chair can be felt against the legs.
  • Reach back to grab the chair with one hand.
  • Maintain stability with one hand up / one hand down until committed to the seat.

Avoid common balance errors:

  • Don’t bring the hand back too quickly (risk of falling forward).
  • Don’t fail to reach back to the chair or slide away (loss of control → fall risk).

Prioritize loading mechanics to protect the “sound” limb

Many people do 90% of the work with the remaining (sound) limb. To reduce wear-and-tear on the sound side:

  • Do as much of the work as safely possible through the prosthetic side.
  • When standing: press the prosthetic side back into the socket/back wall to help you rise while taking some load off the sound leg.

Productivity / skill-building methodology embedded in the training

Progress transfer difficulty as strength improves

  • First use an assistive device (walker) for stability.
  • Then practice sit-to-stand without assistive devices as the patient gains control.

Mechanical-knee vs microprocessor-knee sitting technique

Mechanical knee (unlock before sitting):

  • Create toe load by stepping slightly back.
  • As toe load increases, press the knee forward to feel it release/unlock.
  • Then grab the chair and sit back.

Microprocessor (using hydraulics):

  • Start the sit by bending the knee while keeping weight on the prosthetic knee.
  • As the knee bends, press down into the heel area (keep weight on the prosthetic side).
  • Increasing “thickness”/resistance indicates the hydraulic engagement; sit down slower for control.

Self-care takeaway (safety-first)

The overall theme is functional safety: controlled mechanics (scoot/hand placement/knee extension), plus protecting the sound limb by transferring more work to the prosthetic side when possible.
