Effect of Damp on Isokinetic Measurements
Physical Therapy, 1983Meaningful use of isokinetic data requires understanding potential sources of variation and error. The purpose of this study was to examine one possible source of variation: the effect of recorder damp settings on Cybex II torque tracings. The effect of damp settings 0 through 4 at speeds of 30 degrees/sec and 75 degrees/sec was assessed by dropping ...

Isokinetic Measurement in Preadolescent Males
International Journal of Sports Medicine, 1986Eighteen preadolescent males (mean age 11.4 +/- 0.59 years) performed 15 knee flexion-extension repetitions on both legs. Peak torque (T peak) and torque acceleration energy (TAE) were measured using the Cybex II Isokinetic system, which permitted a study of the effect of limb velocity on T peak, TAE, and reciprocal muscle group ratios.

Ageing and isokinetic plantar flexion
European Journal of Applied Physiology and Occupational Physiology, 1987Isokinetic torques (Cybex II) of the plantar flexors in 25 healthy men were compared at 5 angular velocities (30, 60, 90, 120 and 180 degrees X s-1). The purposes were to compare plantar flexion torques in young and old subjects, and to determine whether the expected decrease was significantly associated with age, physical activity, or aerobic fitness.

Isokinetic Muscle Function in COPD
Chest, 2002Exercise limitation in patients with COPD has been attributed to impaired ventilation and reduced skeletal muscle function. We have previously used a combination of FEV(1) and leg muscle function (work achieved during a 30-s isokinetic sprint test) to predict progressive exercise capacity.

Errors in the use of isokinetic dynamometers
European Journal of Applied Physiology and Occupational Physiology, 1981The use of constant velocity dynamometers in functional testing and in exercise and therapy programs has been increasing in the past few years. For movements in the horizontal plane there are no gravitational errors. However, in vertical movements the limbs are not only working against the dynamometer but also are either aided or opposed by gravity ...

The hallmark of success in orthopaedic surgery is the quantification of functional results. As far as the patients are concerned, subjective evaluation still plays an important part in relation to relief of symptoms and disability and return to daily activities. In order to compare the results of different methods of treatment or different protocols in

Clinical applicability of isokinetics: A review
Clinical Biomechanics, 1991The purpose of this paper is to review the recent advances made in the field of clinical isokinetics. Presentation of various methodological issues is followed by description and discussion of the role of isokinetic dynamometry in the assessment and treatment of orthopaedic disorders, mainly of the knee and trunk regions. Attention is also drawn to the

Conditions of isokinetic knee flexion that enhance isokinetic knee extension.
Medicine and science in sports and exercise, 1990The results of two experiments are reported. The purpose of the initial investigation was to determine the effect of isokinetic knee flexion contraction intensity on subsequent knee extension contraction. Seven subjects performed ten isokinetic knee flexion-extension cycles at six isokinetic velocities under two antagonist contraction conditions.
