OBJECTIVE: To evaluate the effect of surgery on muscular strength and endurance in @entity1 with @entity459 ( @entity2742 ). DESIGN: Prospective open study. SETTING: University hospital, Sweden. SUBJECTS: Nine @entity1 undergoing @entity2742 surgery and nine matched @entity1 undergoing thyroid resection who acted as controls. INTERVENTIONS: Concentric and eccentric endurance was evaluated with a test comprising 100 repeatedly executed muscle action at 90 degrees.s-1. Blood samples obtained before and after operation were analysed for @entity460 , @entity1391 , thyroid stimulating hormone (TSH), and @entity461 ( @entity461 ) concentrations. MAIN OUTCOME MEASURES: Peak torque during maximum voluntary concentric and eccentric muscle actions at 90 degrees.s-1 before, three months and one year after operation. RESULTS: There were no differences in concentric and eccentric peak torque before and after operation either within or between groups. Concentric and eccentric endurance were similar in the @entity2742 group and controls before as well as after operation. The return of @entity460 and @entity461 concentrations to their reference ranges after parathyroidectomy did not correlate with changes in concentric and eccentric peak torque. CONCLUSIONS: The subjective improvement in muscle endurance which is often encountered in @entity1 with @entity2742 after operation is not associated with an objective increase in muscle strength or endurance as measured by isokinetic muscle performance.
