What is the Biodex isokinetic dynamometer?

The Biodex System 4 Dynamometer provides objective, reproducible measures that can be correlated with the physical demands of different jobs, as determined by the Department of Labor.

What is an isokinetic dynamometer used for?

An isokinetic dynamometer is a device used within sports and exercise science as well as clinical testing environments that is used to evaluate joint torque. Isokinetic dynamometers are able to test the strength (torque) and power of different muscle groups.

What is the Biodex system?

The Biodex is a multi-mode computerized robotic measuring instrument designed to measure muscle strength. It measures muscle strength by applying constant resistance against muscles in repetitive motions quickly and as powerfully as possible.

How does the biodex test work?

The Biodex test involves utilizing a computer assisted machine to assess the patient’s isokinetic strength. When performing these two motions, knee extension and knee flexion, the machine is able to measure the strength output by muscles on both sides of the upper leg.

What can Biodex system 4 dynamometer be used for?

Biodex System 4 – Isokinetic Dynamometer… The Biodex System 4 Isokinetic Dynamometer is a hi-tech device used for muscle testing and rehabilitation by medical and physiotherapy professionals.

Is the Biodex system 3 Pro isokinetic reliable?

Joshua M Drouin 1 , Tamara C Valovich-mcLeod, Sandra J Shultz, Bruce M Gansneder, David H Perrin Affiliation 1Department of Public Health, Georgia Southern University, PO Box 8076, Statesboro, GA 30460-8076, USA. [email protected] PMID: 14508689 DOI: 10.1007/s00421-003-0933-0 Abstract

What’s the passive speed of a Biodex dynamometer?

Passive speeds can be set as low as .25 degree per second and as fast as 300 degrees per second. The very slow speeds allow for overcoming the natural stretch reflex. Biodex software includes specific protocols for active and passive joint repositioning. Higher speeds in passive mode are ideal for active assistive exercise.

How is torque measured in Biodex system 3 Pro?

Torque measures were assessed isometrically by hanging six different calibrated weights from the lever arm. Velocity was assessed (30 degrees/s to 500 degrees/s) across a 70 degrees arc of motion by manually accelerating the weighted lever arm.
