Objectives. To compare muscle performance in women with fibromyalgia and in healthy women. Patients and methods. Sixteen women with fibromyalgia syndrome (FMS) and 85 healthy women who were physically inactive or engaged in recreational sports underwent measurements of four parameters: maximal concentric isokinetic muscle strength of the knee extensors and flexors in the dominant limb, isometric grip strength on a Colin dynamometer, muscle fatigue resistance during 30 maximal concentric isokinetic contractions of the dominant knee flexors and extensors at 180° angular velocity, and static endurance during posture maintenance. Results. All muscle variables were decreased in the FMS patients as compared to the controls.The decreases were more marked during aerobic than during anaerobic exercise.Mean decreases were 39% (P<0.001) for muscle strength, 40% (P<0.0001) for fatigue resistance, and 81% (P<0.0001) for static endurance. Pain during exercise as evaluated using a visual analog scale was more marked in the FMS patients. Conclusion. This study of the three pathways supplying energy to muscle confirms that muscle function is globally impaired in FMS patients.The results suggest that the impairment predominates on aerobic processes.

We determined the frequency of strength disorders in 26 athletes with a history of hamstring muscle injury and recurrent strains and discomfort. We also assessed the effectiveness of rehabilitation to correct muscle performance. After concentric and eccentric isokinetic assessment, 18 athletes were found to have strength deficits, as determined by statistically selected cutoffs of peak torque, bilateral differences, and the flexors/quadriceps ratio. The discriminating character of the eccentric trial was demonstrated, combining a preferential eccentric peak torque deficit and a significant reduction of the mixed eccentric flexors/concentric quadriceps ratio. The athletes with muscle imbalances followed a rehabilitation program individually adapted from their strength profile. Treatment length was from 10 to 30 sessions and resulted in isokinetic parameter normalization in 17 of 18 subjects. Isokinetically corrected subjects were observed for 12 months after return to athletics. None sustained a clinically diagnosed hamstring muscle reinjury. Subjective intensity of pain and discomfort were significantly reduced, and they all returned to their prior level of competition. These results demonstrate that persistent muscle strength abnormalities may give rise to recurrent hamstring injuries and discomfort. An individualized rehabilitation program emphasizing eccentric training based on specific deficits contributes to a decrease in symptoms on return to sports. [less ▲]

The assessment of human muscle strength is of considerable value in various pathological states with modifications of the performance level. The original concept of isokinetic dynamometry provides a precise and reliable quantification of strength. Identification of underlying deficits in bilateral and reciprocal muscle group relationships plays a great role in the treatment of anterior cruciate ligament (ACL) reconstruction and muscle injuries. The value of this type of assessment for prevention in uninjured subjects practicing sports at risk is suggested. Rehabilitative use of isokinetic includes muscle strengthening and tendinitis treatment by means of eccentric exercises. [less ▲]
