• Registration Number: NCT06418152
• Lead Sponsor: Jay Alberts

Brief Summary

The goal of this project is to evaluate the safety and preliminary effectiveness of utilizing a digital therapeutic, Dual-task Augmented Reality Treatment (DART) protocol, for the treatment of postural instability and gait dysfunction (PIGD) in individuals with PD with a previously implanted deep brain stimulator (DBS).

Detailed Description

Multi-Modal Training in PD patients: In order to treat dual-task impairment (difficulty performing two tasks at once), multi-modal treatment (MMT) was designed to target PD-specific declines in the areas of cognitive function and gait and posture impairments. Briefly, MMT training consists of simultaneously training a motor and cognitive task. The motor aspect of MMT stresses high velocity, high amplitude training principles while the cognitive aspect stresses commonly impaired cognitive domains in PD such as attention and executive function. An example of an MMT task is marching while spelling words backwards.

Delivery of a Digital Therapeutic via Augmented Reality for the Treatment of PIGD: The MMT intervention is well-suited for integration into an augmented reality (AR) platform as it consists of the patient performing a series of cognitive and motor tasks simultaneously while the patient receives knowledge of performance and results from a therapist. The Microsoft HoloLens is an untethered, AR headset used in applications as broad as teaching anatomy, displaying fine art and gaming. With AR, the user maintains contact with the physical world and the people in it. The HoloLens uses AR technology to place holograms, objects made entirely of projected light, into the user's physical environment; hence creating a first-person mixed reality environment. These holograms can be viewed from different angles and distances, can be two-dimensional or three-dimensional, can appear life-like, can move, be shaped, and change according to interaction with users' or the physical environment in which they are projected, depending on the programming. The MMT was previously developed for the Dual-task Augmented Reality Treatment (DART), which delivers MMT training on a head-mounted AR display. The DART platform was successfully piloted in 50 individuals with PD who did not have DBS (IRB # 20-207). The results of the project indicate that DART is an effective method of training for individuals with PD. The goal is to expand the impact of that project through the investigation of DART in individuals with PD who have previously undergone DBS surgery.

Arm && Interventions

Group	Intervention	Description
Interventional Arm	Multi-modal treatment	Up to five individuals with PD and DBS will receive the DART intervention. The 16 DART sessions will be delivered over an 8-week period (but not more than 10-weeks). Each DART session will consist of approximately 30-minutes of dual-task activity and will be scheduled over a 1 hour period. A physical therapist or physical therapist assistant will oversee each session. Exercises will be progressed based on results from the DART platform, feedback from the participant, and the clinical expertise of the physical therapist or physical therapist assistant
