Robot-Assisted Rehabilitation After HIV-Associated Stroke: Botswana

Not Applicable

Active, not recruiting

• Conditions: HIV/AIDS; Stroke
• Interventions: Other: Robot Therapy

• Registration Number: NCT04488250
• Lead Sponsor: University of Pennsylvania

Brief Summary

Today, nearly 37 million people are living with HIV (PLHIV) worldwide and 30 to 40% of them will have neurologic complications leading to disability. Our long-term working hypothesis is that an effective solution for increasing rehabilitation access in Botswana and improving functional outcomes of PLHIV having experienced a stroke with or without HIV uses an affordable robot and mobile health technologies to create a cost-effective intervention strategy. For this project, we test the feasibility of affordable robot therapy.

Detailed Description

We will test the feasibility of affordable robot therapy in three Aims. In Aim 1, we will optimize for the Botswana context, an affordable technology-based robot system with four exercise stations. We will optimize a prototype of our provisionally patented robot gym system, REHAB CARES, for therapy. Optimization will include increasing cost-effectiveness, utilizing more local resources and manufacturing, and using mobile health android platforms for games and data acquisition. In Aim 2, the efficiency of the newly modified robot system compared to standard of care will be assessed using 30 patients who have experienced a stroke, with or without HIV, will be recruited from those who are being treated by Princess Marina Hospital (PMH) and living in the surrounding community. They will receive therapy using the robot gym system and receive standard of care. We will assess functional outcomes including motor impairment, function, and quality of life. The study outcomes would then inform rehabilitation practices for PLHIV with stroke, with or without HIV, and suggest that affordable technology-mediated rehabilitation can reduce their motor dysfunction and resulting long-term disability.

Arm && Interventions

Group	Intervention	Description
Low-to-mid functioning HIV/AIDS patients	Robot Therapy	Low-to-mid functioning HIV/AIDS patients greater than 18 years of age with stroke co-morbidity.
Stroke survivors	Robot Therapy	Stroke survivors greater than 18 years of age with hemiplegia with and without HIV/AIDS.

Primary Outcome Measures

Name	Time	Method
Rehabilitation Capacity Questionnaire	At 0 week	Survey for all therapists and rehab professionals - up to 1 hour; interview
Change from baseline assessment of 10 Meter Walk Test	at 8 weeks	Measure gait distance capacity. Measured in meters. Longer distance means lower impairment.
Modified IBM Usability Satisfaction Questionnaire	At 8 Weeks	Assess usability of the robot system with patients and therapists
Change in Baseline assessment of motor impairment	At week 8	The Fugl-Meyer measure of motor impairment in the upper limb. Max is 66. Min 0; higher is better. up to 30 minutes to complete
Change from baseline assessment of Timed up and go	at 8 weeks	Timed up and go - Measure gait capacity. Measured is minutes. Longer times indicate higher impairment.
Change from baseline assessment of # of blocks that can be grasped and moved	at 8 weeks	Box and Block Test is a reach and grasp test - gross motor function. Measured in # of blocks. Higher number of blocks means lower impairment.
Change from baseline assessment of fine motor grasp	at 8 weeks	Grooved Peg-Board Test is measure of fine motor grasp. Measured in times and number of pins placed. More pins placed means lower impairment.
Change from baseline assessment of stroke impact scale	at 8 weeks	quality of life questionnaire; self-reported. The Stroke Impact Scale (SIS) assesses other dimensions of health related quality of life: emotion, communication, memory and thinking, and social role function. Higher scores means less impaired. Lower score is more impaired.
