The assessment of range of motion and lower limb muscle activity in patient with Parkinson compared with an elderly subject

Parkinson Diseases (PD) is a progressive deficit of central nervous system. This disease affects gait performance. The objective of this study was to assessment the range of motion and muscle activity of lower limb in PD patient compared to normal elderly.
one patient with PD (height=173 cm, weight=63 kg, age 53 years) and one normal elderly subject (height=172cm, weight=70kg, age 51years) were participated in this study. VICON motion analysis system was used to measure kinematic variables. Moreover, MA300-16 was used to measure EMG activity of lower limbs muscles. Data were evaluated using Repeated Measure with significant point set at p The duration of mid stance and terminal swing phase of PD patient was greater than normal elderly in right limb 20.3% and 11.6 % and in left limb 19.4% and 2.3% respectively. The intensity and duration of muscle activity of tibialis anterior, vastu smedius and biceps femoris was significantly increased in PD patient compared to normal elderly.
The percent of gait cycle phases changes in PD patients. The intensity of muscle activity increases in PD patients than that of normal subjects that means PD patients’ muscles are weaker. So strengthen of ankle plantar-flexor, knee and hip extensor must be considered in rehabilitation programs
