Frequency vs Error Augmentation Training in Acute Physical Therapy Post Stroke

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.

About this study

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.

Treatment and study plan

Frequent PT

Behavioral

Physical therapy services twice a day Monday through Friday and daily Saturday and Sunday. Most sessions are geared toward bed mobility, transfers and gait training with therapeutic exercises provided to target any muscle weakness identified.

Intense PT

Behavioral

Will receive error augmentation training 3-5x/wk while inpatient Standard of care PT with the addition of error augmentation principles (making hard tasks harder and increasing difficulty of tasks with added resistance to already weakened muscles) to address at least 2 stroke deficits or limitations.

Other names: Error Augmentation Training

Primary outcomes

  1. Change in Postural Assessment Stroke Scale (PASS)

    Time frame: From date of PT evaluation up until 90 day stroke follow up post hospital discharge

    The scale measures 12 items of balance in sitting, lying and standing with increasing amounts of difficulty. It consists of a 4 point scale, measured from 0 to 3 with scores that range from 0-36. Patients with a lower score have a more severe impairment, and patients with a higher score have a less severe impairment.

  2. Change in Activity Measure for Post Acute Care (AM-PAC)

    Time frame: From date of PT evaluation up until 90 day stroke follow up post hospital discharge

    The scale measures basic mobility in the hospital setting including moving around in bed, getting out of bed, sitting and standing, moving from a bed to a chair, walking, and going up and down stairs. It consists of a 4 point scale measured from 1 to 4 with scores that range from 6 to 24. Patients with a lower score have a more severe impairment, and patients with a higher score have a less severe impairment.

Secondary outcomes

  1. Patient's Modified Rankin Scale (mRS) Post Acute Stroke

    Time frame: On date of PT evaluation

    The scale is a questionnaire that asks patients about their ability to perform activities of daily living (ADL's) taking into account their physical, mental, and speech performance. On admission the questionnaire focuses on their ability to perform ADL's prior to their stroke. At discharge and at 90 day follow up the questionnaire focuses on their ability to perform ADL's at that time point. It is scored from 0 to 5. Patients with a lower score have a less severe impairment, and patients with a higher score have a more severe impairment.

  2. Change in National Institute of Health Stroke Scale Score (NIHSS)

    Time frame: From date of PT evaluation up until 30 day stroke follow up post hospital discharge

    The scale measures the severity of symptoms associated with patient's stroke. It assesses the severity of impairments related to stroke. The impairments are graded on a 3-4 point scale with scores that range from 0-42. Patients with a higher score have a more severe impairment, and patients with a lower score have a less severe impairment.

  3. Length of Stay

    Time frame: From day of hospital admission to day of hospital discharge, measured in days; up to 30 days.
