“pill rolling” tremor of the hand
increases with emotional stress and fatigue
reduced when patient relaxed and disappears when sleeping

rigidity - increased resistance to movement (not velocity dependent)
“heaviness” or “stiffness”
AYMMETRICAL
PROXIMAL to DISTAL
cogwheel or leadpipe

akinesia - with voluntary movements
freezing gait
slowness in movement - reduced in speed, amplitude, range

postural instability - later in disease
abnormal posture synergies lead to reduced balance
flexed, stooped posture
increased weakness of trunk extensor muscles
kyphosis
increased falls - COG shifts forward

42
Q

Parkinsons gait

A

festinating gait - shortened strides with progressively increasing speed
stooped posture
freezing episodes - exacerbated by obstacles, doorways, stress
anteropulsive (forward festinating) vs. retropulsive (backward festinating)
shuffling steps - reduced hip, knee, ankle flexion
reduced trunk rotation
reduced arm swing
difficulty with dual commands, or increased attentional demands

43

45
Q

Parkinsons interventions

A

medications to slow disease process/symptom management

medications should not be discontinued suddenly - can be life threatening
side effects - dyskinesia, dystonia, motor fluctuations

46
Q

PT management

A

exercise training
decline treadmill walking to reduce stooped posture
blocked training sessions with repetition instead of random practice
reduce cognitive competition demands

auditory cues - clapping, rhythmic music, metronome
visual cues - stepping over tape lines
tactile cues - tapping thigh, hip, leg
cognitive cues - imagery of stepping appropriate length (good for freezing)
