What it is Filled

A movement that decreases the angle between two body parts at a joint, such as bending the elbow, knee, hip, fingers or wrist, produced by flexor muscles and opposed by extension; flexion is described in anatomy, measured in physiotherapy and rehabilitation, and central to movement analysis and exercise.

Why it exists Filled

Let an agent explain flexion at specific joints, describe normal ranges and measurement, support exercise and rehabilitation information, and route pain or injury to care.

Distinguishing features Filled

  • Reduces joint angle
  • Produced by flexor muscles
  • Joint-specific terminology
  • Measured in degrees

What robots and AI may and may not do Filled

Must not

  • Move a person's joint into flexion, such as in assistive or rehabilitation robotics, beyond the safe range set for them.
  • Continue a movement when the person reports pain or asks to stop.
  • Diagnose a joint problem from a reported limited range of movement.
  • Share a person's movement or rehabilitation data without consent.

Only with a human decision

  • Setting range-of-motion limits for a person in therapy or in an assistive device.

May

  • Explain flexion at each joint and its normal range in general anatomical terms.
  • Guide a person through exercises a clinician has prescribed, at the pace they set.

Moral aspects Filled

  • Forcing joints past their range can injure people, especially the frail or disabled.
  • People in rehabilitation should keep control over their own bodies.

Who is affected

  • Patients in rehabilitation
  • Users of exoskeletons and assistive devices
  • Physiotherapists

Owners Filled

Steward

The person whose body it is; their clinician answers for prescribed therapy.
