Psychometric properties of 3-meter backward walk test (3MBWT) in people with Parkinson disease.

Background And Purpose: The purpose of this study was to investigate the 3-meter backward walk test (3MBWT) in individuals with Parkinson Disease (PD) to determine the following: (1) concurrent validity with other gait velocity measures and (2) interrater and intrarater reliability of in-person and video assessment.

Methods: A convenience sample of 25 people with PD participated. Forward gait velocity was measured using a computerized walkway (Zeno Walkway System), the 10-meter walk test (10MWT), and 4-meter walk test (4MWT).

Progressive muscle relaxation, meditation, and mental practice-based interventions for the treatment of tremor after traumatic brain injury.

Background And Purpose: Individuals post traumatic brain injury (TBI) are likely to experience cognitive, sensory, and motor impairments. Tremor is a common movement disorder that can affect this patient population. The purpose of this case report was to describe the effects that progressive muscle relaxation, meditation, and mental practice-based interventions have on the treatment of chronic right upper extremity tremor in a patient post-TBI.
