Q

Asynergia

A

Loss of ability to associate muscles together for complex movements

17
Q

Rebound phenomenon

A

Loss of “check reflex”, halt of forceful movements when resistance is eliminated

18
Q

Resting tremor

A

At rest tremors, disappears with movement
Hand tremor =pill rolling
Head, neck, trunk, oral area

19
Q

Hypokinesia

A

Decreased ROM

20
Q

Plastic rigidity

A

Constant resistance to passive movements in any direction regardless of speed

21
Q

Cogwheel rigidity

A

Combining lead-pipe rigidity with tremor

Rigidity causes a catch and tremor allows release

22
Q

Festination

A

Shuffling gait with short steps and progressive increase in speed

23
Q

Propulsion

A

Festination while walking forward

24
Q

Retropulsion

A

Festination while walking backward
