I undertook this study to determine the test-retest variability and reliability of the pendulum test for muscle spasticity performed with the Cybex II isokinetic dynamometer. Thirty patients, with intracranial lesions and hemiplegia of 15 days' to 3 years' duration, were tested four times, consecutively. With the patients lying supine, the angle of flexion, at which the knee first reversed dire...

Using the Kin-Com (Chattecx Corp, Hixson, TN) isokinetic dynamometer, 20 university females (age = 21.6 ± 1.4 years, wt = 61.73 ± 7.3 kg, ht = 162.81 ± 5.8 cm) performed concentric and eccentric isokinetic contractions at nine different velocities. At each velocity, subjects performed two submaximal and one maximal concentric and eccentric familiarization contractions. Three alternating concent...

Purpose: Correct proprioceptive information and muscle balance of the ankle joint muscles are essential in preventing sports injuries. This study aims to investigate effect closed kinetic chain exercises on proprioception inversion/eversion strength imbalance track field athletes with medial tibial stress syndrome. Methods: was a randomized controlled trial study. In present study, 22 male hist...

Longer life expectancy is resulting in increasing numbers of elderly adults with mental retardation (MR). The objective of the study was to compare lower limb isokinetic muscle power, locomotor performance and flexibility of aged adult mentally-retarded individuals with and without Down's syndrome (DS). Nine subjects with MR and DS (mean age 61), and sixteen subjects with MR and without DS (mea...

Previous studies demonstrated significant increases in the shoulder internal rotators' peak torque values and unilateral muscular imbalances of the shoulder rotators after a competitive swim period. However, there are no similar data concerning the knee muscles. The purpose of the current study was to examine the effects of a six-month training period on knee flexor and extensor peak torque val...

OBJECTIVE Muscle receptors and selected anabolic effects have been identified for both insulin-like growth factor I (IGF-I) and 1,25-dihydroxyvitamin D (1,25(OH)2D3). The aim of the present study was to test the hypothesis that the decreasing concentrations of these endocrine factors might be involved in the decline in muscle function that characterizes normal human ageing. DESIGN Cross-secti...

The aim of the study was to determine the profile of isokinetic strength of elite young soccer players (n = 12, mean age 17.5 ± 1.5 years). Assessment was performed on the isokinetic dynamometer. We evaluated: maximum peak muscle torque of knee extensors (PTE) and flexors (PTF) in both legs, ipsilateral ratio of muscle torque for both preferred and non-preferred extremities (H:QP and H:QN, resp...

OBJECTIVE To determine whether there is side to side difference of the trunk rotation muscle in Korean male professional golf players. Healthy controls who did not play golf were also evaluated and compared with professional golf players. METHOD Fifty-one professional golf players and 50 healthy controls participated in this study. Bilateral isokinetic trunk rotation strength that represented...
