Isokinetic exercise has become an increasingly popular modality in rehabilitative medicine during the past decade. The facility by which isokinetic dynamometers provide information about dynamic muscle contractions has, no doubt, been a major factor in this Cited by: Moved Permanently.

The document has moved by: Isokinetic dynamometry is also commonly used to assess lower limb strength and power and has consistently been found to elicit 'moderate' to 'excellent' test-retest reliability with ICC values between tested over a range of velocities and muscle actions (Abernethy et al., ; Gleeson and Mercer, ; Li et al., ; Pincivero et.

ISOKINETIC TESTING AND DATA INTERPRETATION PRINCIPLES OF ISOKINETIC The principle behind Isokinetic exercise and testing is that the lever arm moves at a preset fixed speed allowing for accommodating resistance to the effort the subject applies.

This mean that the resistance encountered by the subject is equal to their Size: KB. Get this from a library. Isokinetics: muscle testing, interpretation, and clinical applications. [Zeevi Dvir] -- "Isokinetics has been written primarily for the clinician in mind as well as for the researcher and expert medical witness.

It provides a wealth of essential information for all practitioners. The content also offers detailed coverage of isokinetic dynamometry (measuring muscle strength and function) in relation to the muscle systems of the major joints. Practically written content clearly describes the basic physiological and biomechanical aspects of isokinetics/5(2).

As isokinetic dynamometry is an absolute performance measure there are certain performance variables it would have to assess accurately.

Detecting longitudinal changes in athletes is one of the fundamental tasks of a performance measure. There are many studies to suggest that seasonal changes in strength can be detected using isokinetics.

In our clinic, we have the privilege to possess a top quality isokinetic dynamometer by Microforce and in this section, you can get.

The evaluation of muscle performance may be accomplished by using a number of tests, including manual muscle testing (MMT), isokinetic dynamometry, and hand-held dynamometry (HHD). In the field of sports medicine, hand-held dynamometry (HHD) is gaining considerable interest over isokinetic testing, since the equipment is not expensive and easy to use on the field or training area of the athlete.

The development of active isokinetic dynamometers has allowed the assessment of muscular moment under eccentric activations that have different characteristics to concentric actions.

It is well documented that at a given angular velocity the eccentric moment is greater than the corresponding concentric moment. The moment-velocity relationship under eccentric conditions has been Cited by: The hallmark features of isokinetic computerized dynamometry are objective, reproducible, and valid measurements.

There are instances in clinical decision making where only high quality, meaningful data should be used to formulate an opinion leading to important recommendations such as return to sport, return to work, and impairment and.

Isokinetic dynamometer reliability studies have been conducted primarily about the knee joint, with less conclusive results at other joints [38].

Isokinetic dynamometry is a method of measuring muscle strength that involves hydraulic or motor-driven devices that impose a constant velocity. Dynamometry measurement of the strength of separate human muscle groups with the aid of special devices called medical dynamometers.

Hand dynamometers are used to measure the strength of the muscles that flex the fingers, a posture dynamometer is used to measure the strength of the muscles that hold the body erect (“posture” strength), and so on.

All comparative measures were statistically insignificant. Conclusion: The findings of this study suggest that measurements of isokinetic shoulder rotation strength are highly prone to both joint specific and non-specific errors.

We had a Cybex (Cybex Orthotron II) isokinetic system which was at the time state of the art (as far as isokinetics went). B y today's isokinetic or active dynamometer standards it was rudimentary to say the least.

Strength and muscular endurance can be measured pdf accurately through the use of an isokinetic machine, the data from these tests can then be used to help us to plan a patient's rehabilitation activities.By the end of this isokinetic dynamometry download pdf, attendees should be able to apply the most appropriate techniques for the measurement of muscle strength and joint function (as suggested by the BASES Biomechanics guidelines).
