Muscle/Movement Impairments

Generalized weakness, secondary to cerebellar dysfunction

Inability to perform coordinated movements

• Involuntary sustained postures
• Peripheral movements without central stability

Sudden, random, involuntary movement

Hypertonicity and resistance in initiation of range that decreases throughout range

• UMN lesion
• Involuntary alternating spasmodic contraction of a muscle due to a quick stretch

• Resistance to movement that has a phasic quality
• Ex: PD

Can’t control the range of a movement and the force of the muscular activity

Related to athetosis but is demonstrates larger axial muscle involvement than appendicular muscles

Muscular twitch caused by random discharge of a LMN and its muscle fibers

Involuntary, violent movement of a large body part

• Uniform, constant resistance to ROM
• Associated with basal ganglia lesion

Severe Hypertonicity where a sustained muscle contraction does not allow any movement of a specified jt

Involuntary, rhythmic, oscillary movement secondary to basal ganglia lesion
