INTRODUCTION: Despite the tremor, bradykinesia and rigidity are the classic motor symptoms of Parkinson's disease (PD), muscle weakness has also been pointed out as an important motor symptom associated to this disease, however this condition is still poorly studied and results are inconsistent. OBJECTIVES: This study aimed to compare quadriceps muscle strength between individuals with PD and neurologically healthy individuals matched for age and gender. We also compared muscle strength in the limb more and less affected by the disease. MATERIALS AND METHODS: This study had the participation of 26 volunteers: 13 from the Parkinson Group (64.08 ± 6.87 years, 73.82 ± 13.03 kg, 1.66 ± 0.07 m;) and 13 from the control group (62.73 ± 6.42 years, 79.46 ± 11.40 kg, 1.71 ± 0.07 m). Peak Torque (PT) was measured in knee extensors using an isokinetic dynamometer at a velocity of 90o.s -1. Student's t-test was used to compare average values intraand inter-groups (p < 0.05). RESULTS: Absolute PT was significantly lower in the Parkinson group (119.29 ± 40.06) when compared to the control group (145.15 ± 20.05 Nm). Among individuals with PD, we found significantly lower values of muscle strength in the more affected limb when compared to the less affected limb (119.29 ± 40.06 N.m vs 128.86 ± 35.56 N.m, P < 0.05). CONCLUSION: Based on the results, we concluded that patients with PD showed a decreased isokinetic PT in knee extensors, and these findings are exacerbated in the limb more affected by the disease.
