Alternative Therapies for Improving Physical Function in Individuals With Stroke

Neurological impairment is a devastating disease for patients and their families and a leading cause of adult disability. Traditional rehabilitative therapies can help regain motor function and ameliorate disability. However, health care reimbursed rehabilitation is usually provided for up to 6 months post stroke (3 months in form of inpatient therapy and 3 months in outpatient therapy). There are increasing community and other facilities offering rehabilitation in form of conventional, recreational and alternative (Yoga, Tai-chi) therapy. However, implementation of these conventional therapy techniques in individuals with neurological disorder impairments is tedious, resource-intensive, and costly, often requiring transportation of patients to specialized facilities. Based on recent evidence suggesting significant benefits of repetitive, task-orientated training, investigators propose to evaluate the feasibility of an alternative dance and gaming based virtual dance and gaming based therapy to improve overall physical function of community-dwelling individuals with neurological impairments, compared to conventional therapeutic rehabilitation. This pilot study aims to systematically obtain pilot data on compliance and efficacy as well as performing power analysis and sample size calculation for developing it into a randomized controlled trial for extramural funding purposes. The objective of the study is to determine the safety, feasibility, compliance and efficacy of an alternative dance and gaming-based virtual gaming therapy to improve overall physical function of community-dwelling individuals with neurologically impairment and compare it to that of conventional rehabilitation and also to determine the gains in community participation and integration with longer-term compliance to the dance and gaming -based intervention.

Detailed Description

This pilot study aims to systematically obtain pilot data on compliance and efficacy as well as performing power analysis and sample size calculation for developing it into a randomized controlled trial for extramural funding purposes. Aim 1: To determine the efficacy of an alternative dance and gaming based cognitive-motor virtual reality therapy to that of a conventional rehabilitation in a clinical setting to improve physical and cognitive function of healthy adults and neurologically impaired community-dwelling individuals under both short duration high intensity and long duration intervention paradigm. The primary safety outcome would be the proportion of patients experiencing intervention-related adverse events during the study period. The primary feasibility outcome would be the total time receiving intervention (i.e. compliance). Motivation index found to correlate highly with compliance will be evaluated by the self-report Intrinsic Motivational Inventory and serve as the secondary factor. The primary efficacy outcome measures to determine improvements in physical function would incorporate main domains: Sensorimotor impairment and function (upper and lower extremity), balance control and fall-risk, cognition, cardiovascular function, and community participation and integration administered pre and post intervention (details in methods). Hypothesis 1: Investigators hypothesize that alternative dance and gaming based cognitive-motor virtual reality therapy and perturbation training would show greater efficacy through improvement in main domains of physical function (sensorimotor, balance control, cognition, fall-risk, and cardiovascular function) compared to the conventional balance training. Aim 2: To determine the compliance and gains in community participation and integration following gaming based virtual reality intervention. Hypothesis 2: With same number of sessions of both types of training, investigators hypothesize that virtual reality based interventions would show better compliance to therapy through better score on Intrinsic Motivational Inventory (IMI) than the conventional therapy. Higher IMI scores in this virtual reality intervention group will be positively correlated with the improvements in quality of life (Motor Activity Log), Community integration (CIQ) and Fall-risk reduction (Falls Efficacy and Activities-specific balance confidence scales).

Aim 3: To compare the compliance and effect of a short duration high intensity training (20 sessions over 6 weeks) with a low intensity longer duration (36 sessions over 12 weeks) balance training for the two types of interventions. Hypothesis 3: It is hypothesized that for both types of interventions, short duration high intensity training will be as effective for improvement in physical function as longer duration low intensity training. However, the compliance of short duration training would be greater (higher IMI score) compared to the longer duration training.

Intervention / Treatment

Experimental: Virtual-reality based dance group; Virtual-reality based dance training - Participants received Virtual-reality based dance training for 6 weeks using the commercially available Kinect dance game (Microsoft Inc., Redmond, WA, U.S.A.) "Just Dance 3". The six week session consisted of 5 sessions/week, next two weeks of 3 sessions/week and last two weeks of 2 sessions/week, for a total of 20 sessions. Participants played on 10 songs for the first 2 weeks, progressing to 12 songs during the 3nd and 4th weeks with an addition of 2 more songs of their choice during the last two weeks. Participants played on alternating slow- and fast-paced songs (each maximum of 4 minutes in duration) with a five minutes break after a set of one slow and fast song.

Behavioral: Virtual-reality based dance training; Participants will receive therapy using the "Just Dance" using the commercially available Kinect gaming system (Microsoft Inc, Redmond, WA, USA. Each song involves repetitive action for each dance step (at least 20 repetitions over the entire song) and visual cues on the screen (a stick figure at the bottom right) indicating the upcoming dance step. Participant's playing the game to reduce risk of exercise related adverse effects. Participants will dance on 10 songs starting from a slow-pace progressing to a medium pace (each max 5 minutes long). Participants will receive 5 minutes rest after playing on each song. This will be conducted by two physical therapists.; Other Names: VR-based dance,; exergaming-based dance

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Postural Stability	Postural Stability can be defined by simultaneous control of center of mass position and velocity during slip-like perturbation relative to the rear edge of base of support (rear heel). The position normalized with the individual's foot length, and velocity by square root of gravitational acceleration and individual's body height. Greater values indicate greater stability.	Baseline (week 0), Mid-training (2nd week), and Post-training (7th week)
Compliance to therapy (total time spent over the intervention duration)	Compliance will be assessed by logs of participation time (total time summed over the intervention duration). This will assess if participants were able to complete and tolerate the intervention. Higher values indicate more compliance.	Baseline (week 0), Mid-training (2nd week), and Post-training (7th week)
Change in reaction time with functional arm reach	Reaction time was evaluated with electromyography as the time elapsed between the final cue, "Go" (at 4s), and the onset of EMG signal (calculated as ±1 standard deviation from baseline). Electromyographic will be used to monitor muscle activity in both upper extremities for stand arm reaching. The test will take about 30 minutes.	Baseline (week 0), Mid-training (2nd week), and Post-training (7th week)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Movement Velocity	Degrees of movement per second of a self-initiated movement. Higher values indicate better performance.	Baseline (week 0), Mid-training (2nd week), and Post-training (7th week)
Change in physical activity	For this purpose, the number of steps taken for up to one week will be measured using a wearable sensor by Tractivity (Huston, Texas). During the initial visit, participant will be given the sensor placed in an ankle band. After initial activity monitoring for one week, participants will be scheduled for the training session. After the training participants post-training one-week physical activity will also be monitored. Higher number of steps, indicate more physical activity.	Baseline (week 0), Mid-training (2nd week), and Post-training (7th week)
Change in Berg Balance Scale	Assess static and dynamic balance control. It is a 14 item scale. Score for each item ranges from 0-4. Item score are then summed and maximum score of 54 can be obtained. Less than 45 on this scale indicates a greater risk for falling.	Baseline (week 0), Mid-training (2nd week), and Post-training (7th week)
