Impact of Intense Physical Therapy on Functional Mobility Outcomes in the Acute Stroke Population - Phase II
Impact of Intense Physical Therapy on Functional Mobility Outcomes in the Acute Stroke Population - Phase II
The Department of Physical Therapy in conjunction with the Comprehensive Stroke Center at the Medical University of South Carolina (MUSC) seeks support for developing an evidence-based approach for the mobilization of patients within the first 24 hours of admission for an acute stroke and for increasing the frequency and intensity of acute PT services while inpatient. This evidence will prepare physical therapists and guide practice in the delivery of acute stroke mobilization in the hospital setting to optimize length of stay, disposition planning, and enhance long term recovery outcomes.
This research hopes to challenge the clinical paradigm regarding the possibility of decreased functional outcomes with early mobilization post stroke. The investigators acknowledge that acute stroke patients may not be able to tolerate an extensive early mobility program but may benefit from shorter more frequent sessions of therapy early in their recovery. Throughout the literature, there are clinical practice guidelines for both the inpatient rehabilitation and outpatient therapy sectors and post stroke recovery. Little is known about the contribution of therapy services in the acute hospital setting and therapy's impact on long term functional gains. This study will compare outcomes (AM-PAC, PASS, length of stay and post discharge mRS) across four groups- 1) standard of care 2) increased frequency 3) increased intensity 4) combined increased frequency and intensity. The goal of this project is to determine the appropriate dosage of post stroke mobility in the acute care hospital setting.
The objective is to determine if changing one component of the overall mobility dosage, adjusting frequency or intensity, will improve patient outcomes. Phase I of this study, performed at MUSC from June 2021-June 2022, demonstrated improved functional mobility outcomes at hospital discharge for patients who received a combination of both increased frequency and intensity of PT services compared to the standard of care approach. Phase II aims to determine if these promising results can be attributed to increased frequency, increased intensity, or a combination of frequent and intense PT sessions. The proposed research will be a multidisciplinary collaborative effort from the Department of Neurology and the Department of Physical Therapy to investigate the best-practice for mobilization in the acute hospital phase of stroke. . Phase II aims to evaluate whether the dosage of increased frequency or increased intensity of Physical Therapy services led to the promising outcomes and functional improvements which the first study demonstrated; the study compares outcomes across four groups- 1) standard of care 2) increased frequency 3) increased intensity 4) combined increased frequency and intensity.
Investigators propose to enroll 168 individuals with acute stroke admitted to MUSC and randomize them into increased frequency, increased intensity, increased frequency and intensity combined and usual care PT treatment groups. This study will be designed as a randomized control trial. Patients who agree to participate, will be assigned (at random) to either a treatment arm which will receive either more frequent therapy services, more intense therapy services (increased intensity by incorporating error augmentation training), a combination of frequent and intense therapy services (frequent bouts of error augmentation training) or to the control group (treatment as usual) which will receive the standard amount of therapy services currently provided in the hospital setting (~3-5 times per week). By studying the balance, walking and success of patients in the treatment groups compared with the standard of care group, the investigators hope to better understand the contribution of intense PT services, frequency PT services, or a combination of intense and frequent PT services on a patient's independence post stroke. Investigators know from phase I of this study that patients provided with a combination of increased frequency and intensity of PT services demonstrated significant functional improvements (measured by PASS and AMPAC) at time of hospital discharge and a decreased length of hospital stay when compared to the standard of care PT group. Phase II will help investigators to determine if these promising results can be best attributed to the intensity and error augmentation training portion of PT services, to the frequency of PT services, or to a combination of both frequent and intense PT services post stroke in the acute hospital setting.
