have utilized body weight support systems during gait training, where individuals are suspended from an overhead harness with straps around the pelvic girdle as they walk on a treadmill. This form of gait training has been shown to improve long-term walking speed and a shuffling gait following a one-month intervention period. Studies are also looking at the effect of tai chi on gait performance, and balance in people with Parkinson's Disease. The first study concluded that tai chi was ineffective since there was no improvement on gait performance and no improvement on the Part III score of the Unified Parkinson's Disease Rating Scale (UPDRS). The second study found that patients taking tai chi improved on their UPDRS score, Timed Up and Go test, six-minute walk and backwards walking. It did not however, show any improvements on their forward walking or their one leg stance test. Speech and occupational therapy One of the most widely practiced treatments for speech disorders associated with Parkinson's disease is the Lee Silverman voice treatment (LSVT). Speech therapy and specifically LSVT may improve speech. People with Parkinson's disease can develop dysarthria which is characterized by reduced speech intelligibility. Prosodically based treatments may help. Occupational therapy aims to promote health and quality of life by helping people with the disease to participate in as much of their daily routine as possible. There is indication that occupational therapy may improve motor skills and quality of life for the duration of the therapy. Rhythmic auditory stimulation Rhythmic auditory stimulation (RAS) is a neurological rehabilitation technique consisting in compensating the loss of motor regulation through an external sensory stimulation, mediated by the sound. This technique relies on the strong interaction between auditory and motor neural system. By synchronizing his footsteps on the emitted sound (that can be "metronome-like" cues or complex music) the patient can improves his gait speed and his stride length. Telemedicine A 2017 one-year randomized controlled trial found that providing remote neurologic care to individuals with Parkinson's Disease in their own homes was feasible and as effective as in-person care. While it can be more difficult for remote caregivers to establish trust while providing remote care, that assessment of video visits in a patient's home found that, after four virtual visits over one year, individuals with Parkinson's Disease preferred their connection with the remote specialist to their local clinician. Benefits of telemedicine include convenience and cost-effectiveness, as
