Abstract

Patients with Parkinson's disease often have difficulty maintaining postural stability. This impairment is attributed to postural adjustment deficits. We studied the postural adjustments associated with the performance of two complex tasks which differed only in the final equilibrium constraints. Ten patients with Parkinson's disease and six age-matched control subjects were asked to raise one leg laterally to an abduction angle of approximately 45° as fast as possible to the right or left in random order. In the first series of tests, the subjects were instructed to maintain the leg at 45°, whereas in the second series they were instructed to place their foot back on the ground. Recordings included ground reaction forces and kinematics. In the patients with Parkinson's disease the final posture for the first task was never maintained. The strategy used to shift the body weight was different for the two groups. In control subjects, it was initiated by a whole body rotation around the ankle followed by a trunk inclination around the hip. Conversely, in patients with Parkinson's disease, the shift of the body weight was initiated by a trunk inclination around the hip and then by a whole body rotation around the ankle. The amplitude of the trunk inclination toward the supporting side was smaller than in the control subjects. The second task with less severe equilibrium constraints was, on the whole, better performed by the patients even though the same postural adjustment deficits were present.

Conversely, in patients with Parkinson's disease, the shift of the body weight was initiated by a trunk inclination around the hip and then by a whole body rotation around the ankle. The amplitude of the trunk inclination toward the supporting side was smaller than in the control subjects. The second task with less severe equilibrium constraints was, on the whole, better performed by the patients even though the same postural adjustment deficits were present.</s0>

<EA>Patients with Parkinson's disease often have difficulty maintaining postural stability. This impairment is attributed to postural adjustment deficits. We studied the postural adjustments associated with the performance of two complex tasks which differed only in the final equilibrium constraints. Ten patients with Parkinson's disease and six age-matched control subjects were asked to raise one leg laterally to an abduction angle of approximately 45° as fast as possible to the right or left in random order. In the first series of tests, the subjects were instructed to maintain the leg at 45°, whereas in the second series they were instructed to place their foot back on the ground. Recordings included ground reaction forces and kinematics. In the patients with Parkinson's disease the final posture for the first task was never maintained. The strategy used to shift the body weight was different for the two groups. In control subjects, it was initiated by a whole body rotation around the ankle followed by a trunk inclination around the hip. Conversely, in patients with Parkinson's disease, the shift of the body weight was initiated by a trunk inclination around the hip and then by a whole body rotation around the ankle. The amplitude of the trunk inclination toward the supporting side was smaller than in the control subjects. The second task with less severe equilibrium constraints was, on the whole, better performed by the patients even though the same postural adjustment deficits were present.</EA>
