2. What is Parkinson’s disease?
• Parkinson’s disease is a progressive neurological condition,
resulting from the degeneration of dopamine producing
neurones in the substantia nigra, which is located within the
basal ganglia, deep in the lower region of the brain, on either
side of the brain stem.
5. .
• Also called Parkinsonian gait or Festinating gait.
• Parkinsonian gait is characterized by small shuffling steps and
a general slowness of movement (hypokinesia), or even the
total loss of movement (akinesia) in the extreme cases.

6. .
• Tottering gait
• Characteristically shows difficulty in initiating gait, rapid short
shuffling steps with loss of arm swing, stooped stance
propulsion.
• Turning or changing direction is particularly difficult and
typically accompanied by taking multiple small steps.

• Freezing of Gait (FOG) is typically a transient episode – lasting
less than a minute, in which gait is halted and the patient
complains that his/her feet are glued to the ground.
• ‘ignition disturbances’
Falls
Falls result mainly due to sudden changes in posture, in
particular turning movements of the trunk, or attempts to
perform more than one activity simultaneously with walking or
balancing

• Stride length (m)
• Cadence (stride/min)
• Double support time

• Decrease hip flexion

Kinematics data
Hip
13. Ankle :
• Reduced ankle moment at loading response.
• Power generation in parkinson disease group deteriorate in
late stance.
Knee:
• Lower power generation during single stance phase of the
gait. This occurs due to limited knee extension during the
stance phase.
• Decreased power absorption at the knee joint during the late
stance and preswing phase.
Kinetics data
14. Hip
• Reduction of max hip extensor moment and decrease hip
power generation in the first double support.
• Also max hip flexion moment and power generation in the
second double support and pre swing reduced.
