Validity and Interrater Reliability of the SOAR Tool during Ambulation in Individuals with Parkinson Disease
AbstractParkinson disease (PD) leads to neurological impairments yet the auditory system remains intact. Rhythmic Auditory Stimulation (RAS) and Patterned Sensory Enhancement (PSE) have been shown to impact gait in PD. Music therapists (MT) can individualize auditory protocols but for a physical therapist (PT) to incorporate PSE into treatment, a new tool is needed. The Synchronized Optimization Auditory Rehabilitation (SOAR) tool is a new software created to simulate PSE techniques and allow for customization depending on the individual’s reaction to the cue. The purposes were to evaluate the validity of the SOAR tool with RAS and the interrater reliability between disciplines’ application of the SOAR tool. Day one - MT measured gait parameters during no cue, RAS, and SOAR tool. Day two - PT measured gait parameters while using the SOAR tool. A moderate to high correlation between RAS and the SOAR tool on gait was found. The interrater reliability between the MT and PT was high. These finding suggest the SOAR tool is an additional auditory cue delivery tool that PTs could use in the treatment of individuals with PD when auditory cues are deemed appropriate and a MT is not an available member of the interdisciplinary rehabilitation team.
