Brief Summary

The following trial evaluates the effect of Tremor Stabilization Algorithms on involuntary hand tremors suffered by Parkinson's patients. These algorithms will be implemented in Virtual Reality (VR). Approximately 300 study subjects are to be randomized to experimental (VR plus algorithms, i.e., intervention) and active comparator (VR only, i.e., control) study arms. Study subjects will perform a postural tremor test (PTT) to elicit postural parkinsonian tremors. Our primary outcome is whether the intervention modifies tremor severity.

Tremor

Outcome Measures

Primary Outcomes (1)

• Tremor reduction

  Our primary outcome is the severity of PTT elicited tremors. Tremors will be recorded by VR motion-capture controllers. Wavelet transformation of this data will be applied to determine tremor severity in the two study arms.

Study Arms (2)

TSA-ON

EXPERIMENTAL

The trial will be composed of two arms: an experimental group with VR with activated Tremor Stabilization Algorithms (TSA-ON). And an active comparator group that is exposed to VR without Tremor Stabilization Algorithms (TSA-OFF control). In both arms, study subjects will be immersed in a stock VR testing environment and will perform a tremor eliciting PTT test.

Other: TSA algorithms

TSF-OFF control

ACTIVE COMPARATOR

The trial will be composed of two arms: an experimental group with VR with activated Tremor Stabilization Algorithms (TSA-ON). And an active comparator group that is exposed to VR without Tremor Stabilization Algorithms (TSA-OFF control). In both arms, study subjects will be immersed in a stock VR testing environment and will perform a tremor eliciting PTT test.

Other: TSA algorithms

Interventions

TSA algorithms OTHER

Our study will be composed of an experimental and an active comparator (i.e., control) arm. Both arms will perform a postural tremor test (PTT) to elicit parkinsonian tremors. The PTT is where subjects stabilize their backs against a wall and position their hands in the air against gravity for two minutes. The experimental arm will receive VR plus activated Tremor Stabilization Algorithms (TSA-ON) while the active comparator arm will receive VR only (TSA-OFF). Thus, subjects in the experimental arm will not see their digital arms tremor while those in the active comparator arm will. Our primary outcome is the severity of PTT elicited tremors. Tremors will be recorded by VR motion-capture controllers.
