The use of isokinetic dynamometers with older adults extends far beyond orthopedics, but the reliability and responsiveness of isokinetic measures in conditions like COPD and stroke are still being evaluated, report experts in Isokinetics and Exercise Science.
Isokinetic dynamometry is a major tool in the measurement of muscle strength in the fields of sports medicine, orthopedic and neurological rehabilitation and exercise physiology.

Its use in older individuals now extends far beyond orthopedics to such conditions as a chronic obstructive pulmonary disease (COPD) and stroke. In a collection of articles published in Isokinetics and Exercise Science, experts address its validity, reliability and responsiveness in older adults.

Isokinetic dynamometers are mechanical devices that are used to test muscle strength. They resist applied forces and control the speed of movement at a predetermined rate and can be used to test limb and/or trunk muscle strength.

Although many older adults are weak due to age or an array of pathologies, the extent of their weakness might escape notice apart from testing with an isokinetic or other type of dynamometer.

This collection of articles is guest-edited by Richard W. Bohannon, DPT, EdD, of Physical Therapy Consultants, North Carolina, USA. Dr. Bohannon is a noted authority in the field who is recognized internationally for his expertise in muscle performance following stroke, hand-held dynamometry and mobility.

He is a licensed physical therapist with 40 years of clinical experience in diverse practice settings including acute care, rehabilitation, outpatient, and home care, and is Editor-in-Chief of the Archives of Gerontology and Geriatrics.

In this issue, experts review the literature and summarize…
