An Interactive Computer Game, Called Duck Duck Punch, for Stroke Rehabilitation at Home and in a Rehabilitation Clinic "DDPHme/Hsp"

Completed

Phase 1/2 Results N/A

Trial Description

This study will determine the feasibility of using an interactive computer game to elicit repetitive practice of paretic arm movements in the homes of community dwelling stroke survivors and during non-therapy hours at an inpatient stroke rehabilitation hospital.

Detailed Description

More than 75% of the 800,000 people who annually suffer stroke exhibit persistent arm/hand hemiparesis restricting independence thus burdening caregivers. Arm motor skill can recover if the rehabilitation program provides an adequate "dose" of repetitive movement practice. However, the vast majority of stroke survivors lack the proper practice-dose because the duration of inpatient stroke rehabilitation is limited by cost, or residence in medically underserved rural settings. To meet the pressing need for innovative cost-effective rehabilitation options, the investigators developed, tested and licensed a prototype virtual environment (VE) for post-stroke arm rehabilitation. Its custom built design motivates extended practice of specific arm motor skills known to improve quality of life. Excitingly, practice sessions do not require direct therapist supervision. Published pilot data demonstrated improved real-world arm movement after VE training. These promising initial results led to software upgrades that will now enable installation and testing in the primary markets for this technology; stroke rehabilitation hospitals, and patients' homes. The overall goal for this small pilot study is to test the feasibility of self-directed VE practice in these settings measured by movement repetitions and motor skill improvement. To that end, this project will address the following Specific Aims (1) Determine the number of daily movement repetitions and treatment effect achieved by inpatients in a stroke rehabilitation hospital who self-direct VE practice sessions during non-therapy hours (evenings, weekends) compared to standard evening activities; and (2) Determine the number of daily movement repetitions and treatment effect achieved by in-home stroke survivors who self-direct daily VE practice sessions compared to a group of in-home survivors with a standard self-directed exercise program.

Conditions

Interventions

  • An interactive computer game Behavioral
    Intervention Desc: Duck Duck Punch is an interactive computer game designed to elicit repetitive practice of paretic arm movements in stroke patients.
    ARM 1: Kind: Experimental
    Label: Duck Duck Punch
    Description: Community dwelling stroke survivors: Stroke survivors will install an interactive computer game in their home. Subjects will be instructed to play the computer game "as much as you want to every day for 7 days." Inpatient stroke patients: The interactive computer game will be installed at a local inpatient stroke rehabilitation hospital. Subjects will be instructed to "play this game as much as you want to during non-therapy hours (evenings and weekends) over the next 7 days."
  • Standard activities Behavioral
    Intervention Desc: For community dwelling stroke survivors this is a hard copy, written/illustrated home exercise program for the paretic arm. For inpatient stroke patients this is standard recreational activities organized by the facility during non therapy hours (evenings and weekends).
    ARM 1: Kind: Experimental
    Label: Standard activities
    Description: Community dwelling stroke survivors: Subjects will receive a hard-copy handout of an arm home exercise program and given the instructions to "do these exercises as many times as you can daily." Inpatient stroke patients: Subjects will be encouraged to participate in standard evening/weekend recreational activities and to "remember to use the paretic arm as much as you can."
