Hypotonia
delayed relaxation of a muscle after a strong contraction
Myotonia
inability to coord. muscles to carry out a vol. movement
Ataxia
partial ataxia, abnormal, diff. in controling
Dystaxia
abnormal shortening of muscle tissue; resistant to stretch
Contracture
complex of symp. caused by poor circ. and may indicate larger circ. problems
Intermittent claudication
sudden, violent invol. contraction
Spasm
wryneck, stiff neck due to contrac. pulling head to the side
Spasmodic torticollis
slowness in movement
bradykinesia
impairment of movement (vol.)
