Trial summary

Arm weakness happens a lot after a stroke. People often get physical or occupational therapy after their stroke to learn how to use their arm again. This study will help figure out how much therapy should be given to restore as much arm function as possible. Read more about this study

About this study

Official title: Dose Response of Movement Practice During Stroke Rehabilitation

Arm weakness happens a lot after a stroke. People often get physical or occupational therapy after their stroke to learn how to use their arm again. This study will help figure out how much therapy should be given to restore as much arm function as possible.

Read the detailed description

Dose has emerged as a key factor promoting functional recovery after stroke. Currently, a lack of data on the dose-response relationship impedes progress in the field of stroke rehabilitation. The goal of the proposed project is to define the range of doses of movement practice that produce the greatest improvements in outcomes in people with chronic stroke. Borrowing from animal models of stroke, dose in humans can be quantified by the number of repetitions of task-specific practice.

Our central hypothesis is that there exists a range of doses for people with stroke, below which, there is minimal benefit, and above which, further practice does not result in further benefit. The range of beneficial doses is likely to vary based on the severity of motor deficits and the presence of non-motor deficits in other domains. Using a randomized, parallel dose-response design, we will evaluate the benefits of four different doses of task-specific upper extremity training with matched schedules of 1 hr sessions, 4 sessions/wk for 8 wks, in 100 people with chronic stroke. Total repetition doses to be evaluated (3200, 6400, 9600, \& individualized-maximum) are based on our preliminary data. The individualized-maximum group may extend their sessions beyond 8 wks until meeting defined stop criteria.

Our primary aim will test whether larger total doses result in better outcomes than smaller total doses. Benefits of the four doses will be evaluated at the impairment, activity, and participation levels, since understanding the dose-response relationship at all levels of measurement is critical for advancing rehabilitation research. We hypothesize that improvements will be greatest in the 9600 and individualized-maximum, followed by the 6400, and then the 3200 repetition dose groups. Our secondary aim is to characterize the dose-response relationship of upper extremity task-specific practice. With data from multiple assessment points, individual curve modeling will be used to estimate dose ranges, below which, there is minimal benefit, and above which, further practice does not result in further benefit. Furthermore, we will determine how various factors modify the dose estimates. We hypothesize that the severity of motor deficits will be the primary modifier of the dose-response relationship, with larger doses needed for those with more mild motor deficits. We further expect that needed doses will be larger for those with depression and hemispatial neglect.

Our team is well-positioned to investigate the critical issue of dose because of our expertise in stroke rehabilitation research and measurement, our understanding of the challenges of clinical practice and clinical research, and our ready access to this patient population. Expected outcomes from this project are empirically-driven estimates indicating the amount of movement practice required to drive maximal improvements and how these estimates can be individually modified for people undergoing stroke rehabilitation. Our estimates will immediately impact rehabilitation research and clinical practice. The importance of this project transcends stroke rehabilitation; our primary results will be of high value to many other rehabilitation populations also impeded by the lack of knowledge regarding dose-response relationships.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intensive task-specific upper extremity rehabilitationOther

    The experimental intervention consists of intensive task-specific upper extremity movement rehabilitation which are appropriately graded and progressed for each subject. This intervention will provide progressive training of these essential components required for upper extremity movement through repeated practice of various tasks, with the desired goal of building the subject's capacity to perform a multitude of UE functions. Subjects will participate in the intervention for eight weeks or more depending on the group they are randomized to.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Action Research Arm Test (ARAT) Score Per Week

    The Action Research Arm Test (ARAT) is a standardized assessment of upper extremity functional capacity. Criterion scores are awarded by a trained assessor as the person performs 19 different items requiring reaching, grasping, and manipulation of various objects. Maximum total score is 57. Minimum total score is 0. Higher scores represent better arm and hand functional capacity. In this study, scores were assesses weekly and the analysis evaluated the rate of change over time in units/week.

    Measured: 9 weeks
