Q

Definition of dystonia

A

type of hypertonia

movement disroder characterized by sustained or intermittent muscle contractions causing abnormal, often repetitive movements, postures or both

resistance to passive stretch of a muscle across a joint, present at low speeds, fluctuates with repeated stretches, and where tactile stimulus or purposeful movement of another body party triggers increased tone or increased involuntary postures

patterned, twisting, or may be tremulous

45
Q

impact wellbeing

associated with orthopedic deformities

46
Q

indication for treatment of dystonia

A

dystonic posutres, hypertonia, and slow involuntary movements that are causing interference

47
Q

definition of spasticity

A

a velocity-dependent resistance of a muscle ot stretch - resistance to externally imposed movement increases with increasing speed of stretch
