Isokinetic Exercise
Pronunciation: eye-so-ki-NET-ik
Exercise performed at constant velocity with variable resistance using specialized equipment.
Full Definition
A type of dynamic exercise performed using specialized equipment that maintains constant angular velocity while providing variable resistance that accommodates the muscle's force output throughout the range of motion. The equipment automatically adjusts resistance to match the force applied by the patient, ensuring consistent speed of movement regardless of the effort exerted. Isokinetic exercise is valuable for objective strength testing, providing precise measurements of muscle performance at different velocities. It is also used therapeutically to strengthen muscles through their full range of motion while minimizing joint stress and providing accommodating resistance that matches healing tissue capabilities.
Usage
Usage note: Requires specialized equipment such as Biodex or Cybex machines. Often used for objective testing.
