isokinetic exercise
Pronunciation: eye-so-ki-NET-ik
Muscle contraction performed at constant velocity using specialized equipment that provides accommodating resistance.
Full Definition
Isokinetic exercise involves muscle contractions where the velocity of movement remains constant while resistance varies throughout the range of motion to match the muscle's force output. This type of exercise requires specialized equipment such as Biodex or Cybex dynamometers that control movement speed and provide accommodating resistance. Isokinetic testing and training are particularly valuable in rehabilitation for objective strength assessment, identifying bilateral deficits, and providing safe strengthening at various speeds. The technology allows for precise documentation of torque production, work capacity, and fatigue patterns throughout the rehabilitation process.
Usage
Usage note: Distinguish clearly from isotonic in clinical documentation. Specify angular velocity when documenting isokinetic protocols.
In Context
- "Isokinetic testing revealed a 15% strength deficit in the involved limb compared to the uninvolved side." — Evaluation report
- "The patient progressed to isokinetic exercise at 60°/sec to address power deficits in the final rehabilitation phase." — Progress note
