OBJECTIVE To investigate the effects of asymptomatic back muscle weakness and spinal deformity on low back pain (LBP). METHODS Sixty healthy subjects without LBP participated in this study. Radiography and an isokinetic/isometric dynamometer were used to respectively measure spinal scoliosis/lordosis and the strength of the trunk flexors/extensors. After 2 years, 48 subjects visited the hospi...

OBJECTIVE To evaluate the test-retest reliability of isometric and isokinetic muscle strength measurements in the upper extremity after stroke. DESIGN A test-retest design. SUBJECTS Forty-five persons with mild to moderate paresis in the upper extremity > 6 months post-stroke. METHODS Isometric arm strength (shoulder abduction, elbow flexion), isokinetic arm strength (elbow extension/flex...

OBJECTIVES The effects of Kinesio Taping (KT) on muscular performance remain largely unclear. This study aimed to investigate the acute effects of KT on the maximum concentric and eccentric quadriceps isokinetic strength. STUDY DESIGN This is a single-blinded, placebo crossover, repeated measures study. METHODS Maximum isokinetic concentric/eccentric extension torque, work, and power were a...

EXERCISE ON AN ISOKINETIC DEVICE INVOLVES THREE DISTINCT MOVEMENT PHASES: acceleration, constant velocity, and deceleration. Inherent in these phases are unique occurrences that may confound test data and, thereby, test interpretation. Standard methods of data reduction like windowing and other techniques consist of removing the acceleration and deceleration phases in order to assure analysis u...

Background: Behçet’s disease (BD) is an idiopathic, multisystemic, progressive disease. The purpose of this study is to compare the knee flexor and extensor isokinetic muscle strengths of Behcet’s patients with that of healthy subjects. Methods: Twenty-five (13 male and 12 female) patients with BD and 25 (15 male and 10 female) healthy individuals were included in the study. Velocities of 90°/s...

Recently, the increase of transfemoral amputees from industrial disasters, traffic accidents, vascular diseases and aging is emerging as a social issue. For transfemoral amputees, it is very important to recover their lost functions. Myoplasty, which is one of above-knee amputation methods that sutures muscles on the femoral stump, is used more commonly than other operation methods because it i...

BACKGROUND Whether passive measures of isokinetic muscle strength deficits and knee laxity are related to the dynamic function of the anterior cruciate ligament-deficient knee remains unclear. HYPOTHESES Arthrometer measurements are not predictive of peak external knee flexion moment (net quadriceps muscle moment), isokinetic quadriceps muscle strength correlates with peak external knee flexi...

Objective: To assess the effects of neuromuscular electrical stimulation (NMES) associated with an isokinetic training program in healthy young men and women. Methods: Twenty participants (ten men, ten women; 21±1.5 years) underwent an isokinetic training program for knee extensors of both sides (three sets of ten concentric repetitions at 30°/s) twice a week for four weeks. One limb underwent ...

OBJECTIVES To evaluate the difference in isokinetic strength of hip muscles between patients with knee osteoarthritis (OA) and matched healthy controls, and to establish the correlation between this isokinetic strength and pain and function in patients with knee OA. METHODS 25 patients with a diagnosis of unilateral knee OA, 25 patients with bilateral knee OA, and 50 matched controls were eva...

Background: Isokinetic dynamometry allows the measurement of several variables related to muscular performance, many of which are seldom used, while others are redundantly applied to the characterization of muscle function. Objectives: The present study aimed to establish the particular features of muscle function that are captured by the variables currently included in isokinetic assessment an...
