Alternative Therapies for Improving Motor Impairment, Fall-risk and Overall Physical Function

Comparing Conventional and Alternative Therapies for Improving Motor Impairment, Fall-risk and Overall Physical Function

Neurological impairment such as stroke and aging is a leading cause of adult disability. Traditional rehabilitative therapies can help regain motor function and ameliorate disability. There are increasing community and other facilities offering rehabilitation in the form of conventional, recreational and alternative (Yoga, Tai-chi) therapy. However, the implementation of these conventional therapy techniques in individuals with a neurological disorder like stroke and the elderly population 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 therapies such as exergaming based therapy to improve overall physical function of community-dwelling individuals with neurological impairments and the elderly, 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 exergaming therapy to improve overall physical function of community-dwelling chronic stroke individuals and the elderly population.

Study Overview

• Status: Completed
• Conditions: Healthy Aging; Chronic Stroke
• Intervention / Treatment: Behavioral: Cognitive-motor exergaming; Behavioral: Conventional balance Training; Behavioral: Dance Therapy for Stroke; Behavioral: Dance Therapy for Older adults; Behavioral: Home education for Older adults

Detailed Description

While conventional balance training facilitates balance control and gait functions, the exercises involved in the training are labor-intensive, highly repetitious leading to monotonicity and decreased motivation levels. Therefore, many health care researchers are involved in identifying various methods to reduce the risk of falls addressing the barriers in conventional training methods while having the potential to translate it at home. A pilot study identified that supplementary cognitive training along with Wii-fit balance training resulted in improving dual-task volitional balance control post-stroke. Based on this preliminary finding, this current pilot study aimed to identify:

1. The efficacy of cognitive-motor exergaming (with Wii-fit) compared to conventional balance training among people with chronic stroke
2. Exergaming (with Kinect) on domains of balance control and cognition among people with chronic stroke
3. The efficacy of Exergaming (with Kinect) compared to conventional balance training method on domains of balance control and cognition among healthy older adults

This pilot study used Wii-fit Nintendo/ Microsoft Kinect, an off the shelf, commercially available and a cost-effective device that provides similar benefits of exergaming. Community-dwelling people with chronic stroke and healthy older adults involved in the study underwent 6 weeks of exergaming or conventional balance training in a tapering manner in a laboratory setting. Participants were assessed for motor and cognitive performance in the laboratory during volitional and reactive balance control while performing a secondary cognitive task. The performance outcome determined the effect on cognitive-motor interference during dual-tasking.

A total of 6 cognitive tasks namely Digit recall, repeated letter, word list generation (category and alphabets), mental arithmetic, analogies. Each session was divided into 3 sub-sessions. Every Wii-fit game was played with any 3 cognitive tasks. The combination of games with cognitive tasks was randomized in such a manner that all the cognitive tasks were played with the Wii-fit games in that session. Breaks were provided after each sub-session or when the participant demanded one or when the research personnel noticed any discomfort of the participant.	Behavioral: Cognitive-motor exergaming; Participants undergo 6 weeks of cognitive-motor exergaming using Wii-fit Nintendo. The 6 weeks included a total of 20 session distributed in the following manner: 5 sessions/week for 1-2 week, 3 session/week for 3-4 week, 2 sessions/week for 5-6 week. Each session lasted for about 90 minutes with rests included.; Other Names: Dual-task training; Wii-fit exergaming; Virtual-reality training

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Movement Velocity (during dual-tasking)	Degrees of movement per second of a self-initiated movement. Higher values indicate better performance.	Baseline (Week 0) and Immediate Post-training (Week 7)
Change in Postural Stability (during single and dual-tasking)	Postural Stability (Laboratory Slip test) can be defined by simultaneous control of center of mass (COM) 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) and Immediate Post-training (Week 7)
Change Cognitive Accuracy (during dual-tasking)	Accuracy (number of correct responses out of the total responses) during the letter number sequencing task. Higher accuracy indicates better performance.	Baseline (Week 0) and Immediate Post-training (Week 7)
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) to Post-training (Week 7)
Change in reaction time with functional arm reach - Dance therapy for people with stroke and healthy older adults	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) and Immediate Post-training (Week 7)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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) and Immediate Post-training (Week 7)
Change in Timed Up and Go test and cognitive Timed up and Go test (seconds)	Assess mobility, balance and walking ability. It is a fall risk predictor. More than 14 seconds taken to complete the test indicates a greater risk for falling.	Baseline (Week 0) and Immediate Post-training (Week 7)
Change in distance covered in Six minute walk test	Assess endurance and walking ability. Total walking distance covered in 6 minutes was recorded.	Baseline (Week 0) and Immediate Post-training (Week 7)
Change in performance on Chair Stand Test	Assess balance, functional mobility and strength. It is the number of times the participant completed sit to stand within 30 seconds.	Baseline (Week 0) and Immediate Post-training (Week 7)
Change in performance on Four Step Square test	Assess balance. The amount of time taken (in seconds) for the participant to complete the sequence of stepping was recorded. More than 15 seconds to complete the test indicates greater risk of falling.	Baseline (Week 0) and Immediate Post-training (Week 7)
Change in Activity Specific Balance confidence	It is a 16 item self-reported physical activity and community integration questionnaire with each item score ranging from 0-100, where 0 indicates no confidence and 100 indicates complete confidence.	Baseline (Week 0) and Immediate Post-training (Week 7)
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) and Immediate Post-training (Week 7)
