Arm Rehabilitation Study After Stroke (ICARE)

Interdisciplinary Comprehensive Arm Rehab Evaluation (ICARE) Stroke Initiative

This study is about arm and hand recovery after a stroke. The investigators are testing an experimental arm therapy called Accelerated Skill Acquisition Program (ASAP) which combines challenging, intensive and meaningful practice of tasks of the participant's choice compared to two standard types of therapy (usual and customary arm therapy totaling 30 hours and usual and customary arm therapy for a duration indicated on the therapy prescription). A second objective is to characterize current outpatient arm therapy (dosage & content) following stroke for individuals who are eligible for ICARE. Eligible candidates must have had a stroke affecting an arm within the last 106 days.

Study Overview

• Status: Completed
• Conditions: Stroke; Cerebrovascular Disorders; Brain Ischemia; Cerebral Infarction; Brain Infarction
• Intervention / Treatment: Behavioral: Accelerated Skill Acquisition Program (ASAP); Behavioral: Dose-Equivalent Usual & Customary Care - DEUCC; Behavioral: Usual and Customary Care - UCC

Detailed Description

Of the 700,000 individuals who experience a new or recurrent stroke each year, a majority have considerable residual disability. Sixty-five percent (65%) of patients at 6 months are unable to incorporate the paretic hand effectively into daily activities. In turn, this degree of functional deficit contributes to a reduced quality of life after stroke. The extent of disability has been underplayed by the use of the Barthel Index that captures only basic activities of daily living such as self-care and does not extend to activities and participation at higher levels of functioning that are most affected by a residual upper extremity disability. The past decade has witnessed an explosion of different therapy interventions designed to capitalize on the brain's inherent capability to rewire and learn well into old age and more importantly for rehabilitation, after injury. The most effective arm-focused interventions with the strongest evidence and potentially the most immediate and cost-effective appeal for the current health-care environment share a common emphasis on focused task-specific training applied with an intensity higher than usual care. Therefore, our primary aim is to compare the efficacy of a fully defined, hybrid combination of the most effective interventions (forced-use/constraint-induced therapy and skill-based/impairment-mitigating motor learning training), the Accelerated Skill Acquisition Program (ASAP), to an equivalent dose of usual and customary outpatient therapy.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: ASAP; A focused, intense, evidence-based, upper extremity rehabilitation program, administered during the early post-acute outpatient interval. The training intervention is based on the fundamental elements of skill acquisition through task-specific practice, impairment mitigation to increase capacity, and motivational enhancements to build self-confidence.	Behavioral: Accelerated Skill Acquisition Program (ASAP); A 30-hour dose is administered over 1-hour visits at a frequency of 3x/week for a 10-week duration. A 2-hour orientation/evaluation session precedes the first visit.; Other Names: ASAP
Active Comparator: DEUCC; Dose-equivalent usual and customary arm therapy administered early post-acutely in the outpatient setting. This is a 30-hour dose equivalency group, administered over 1-hour visits at a frequency of 3x/week for a 10-week duration.	Behavioral: Dose-Equivalent Usual & Customary Care - DEUCC; Usual and customary arm therapy administered early post-acutely in the outpatient setting, adjusted for dose, but otherwise administered in accordance with usual and customary practices. This is a 30-hour dose equivalency group, administered over 1-hour visits at a frequency of 3x/week for a 10-week duration.; Other Names: DEUCC
Other: UCC; Usual and customary arm therapy administered early post-acutely in the outpatient setting. This is an observation only group with treatment dose administered in accordance with usual and customary practices.	Behavioral: Usual and Customary Care - UCC; Usual and customary arm therapy administered early post-acutely in the outpatient setting. This is an observation only group and treatment dose will be administered in accordance with usual and customary practices.; Other Names: UCC
