Introduction: Muscular weakness, particularly weakness of
lower limb muscles is a symptom of Parkinson disease, which, together with
other symptoms, will result in a variety of movement disorders. This research
is designed to assess the effectiveness of a water-based exercise program on
the lower limb muscles strength of Parkinson patients' knee joints. Materials and Methods: In a semi-experimental study, 20 patients who
referred to neurologist offices in the city of Isfahan volunteered for this
study, and then randomly selected an exercise (n=10) and control (n=10) groups.
Subjects of exercise group completed a eight-week water-based exercise training
program consisted of three sessions per week, each session lasting 45 to 60 minutes,
while the control group were followed and during this period they did not
experience any exercise. Peak torque of the knee flexors and extensors using isokinetic dynamometer
(Biodex, Systems III) during eccentric and concentric contractions at velocities
of 60 and 180 degrees/s before and after 8 weeks of water-based exercise
program were measured. Results: The exercise group demonstrated significant
increases in peak torque of the knee flexors and extensors at velocities of 60
and 180 degrees/s before and after 8 weeks of water-based exercise program
