      Movement problems related to Parkinson’s disease (PD) have been shown to have a profound effect on functional independence and reported quality of life. Within the constellation of movement signs of PD (tremor, muscle rigidity, bradykinesia/hypokinesia, and postural instability), impaired arm swing is often the earliest-recognized symptom. It is also a strong independent predictor of greater fall risk and morbidity/mortality risk. Early treatment for movement problems such as impaired arm swing is associated with the greatest improvement in these impairments. However, movement problems often coincide with impaired processing of sensory information, leaving many people with PD with inadequate awareness of their posture and limb position. Thus, PD-related gait deficits are difficult for people to correct by themselves. External cueing techniques (such as visual cues in the environment or auditory cues for pacing and rhythm) have shown promise in improving parameters such as gait speed, s
