When Mary Free Bed Rehabilitation Hospital conducts research, it’s not only for the future benefit of science and medicine. Our team is dedicated to generating evidence-based, innovative treatment and applying it as quickly as possible to help people recovering from serious injuries or illnesses.

The research efforts of our doctors, therapists, nurses and other professionals often lead to discoveries with a timely and positive impact for our patients. Research is done with the conviction it will help restore hope and freedom for children and adults with physical disabilities.

Mary Free Bed has created an infrastructure through the John F. Butzer Center for Research & Innovation to support our physicians and staff with research endeavors and to facilitate scholarly activity. Our efforts include original research, participation in multicenter studies and sponsored clinical trials.

Current Studies

Active recruitment opportunities include:

Sleep for Stroke Management and Recovery Trial (Sleep SMART)
Mary Free Bed is participating in the Stroke Net study Sleep SMART. This 110-site study randomizes participates who have sleep apnea to test whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) is effective for secondary prevention and recovery after stroke. Eligible participants must be referred from acute care and receiving inpatient therapeutic services for a stroke diagnosis. For more information, click here.

Bone Health Biobank
Researchers are collecting saliva samples from Mary Free Bed patients who have a bone health diagnosis. Genetic mapping will be done to assess relationships with specific gene profiles and diagnoses. Results may contribute to changes in clinical practice and treatment of diagnoses, such as osteoarthritis and osteopenia. Eligible participants must have a bone-related diagnosis and be treated at Mary Free Bed.

Defining Trajectories of Linguistic, Cognitive-Communicative and Quality of Life Outcomes in Aphasia
The objective of this study is to describe the trajectories of linguistic, cognitive-communicative and health-related quality of life outcomes following stroke in people with aphasia during inpatient and outpatient rehabilitation to 18 months following their stroke. A sample of 300 consecutively admitted stroke patients with aphasia recruited at three Midwest rehabilitation hospitals will complete measures of linguistic and cognitive-communicative performance and the Quality of Life Neurological Disorders Measurement instruments during rehabilitation and at three-, six-, 12- and 18-months post stroke. We will model outcomes as individual and group trajectories, allowing us to develop individual predictions that could inform clinical planning and decision-making for new patients.

Patient Population Assessment and Functional Outcome Measure of Post Coronavirus Disease (COVID-19) in an Inpatient Rehabilitation Facility
Researchers at Mary Free Bed are mapping out and describing the functional outcome status of people who had/have COVID-19 for up to six months post-positive diagnosis. Eligible participants must be enrolled from inpatient rehabilitation.

The Role of Music Therapy in Visuospatial Neglect
Researchers are evaluating the potential benefit of musical neglect training in people with left-sided visuospatial neglect secondary to a right hemisphere stroke. Eligible participants must be enrolled from inpatient rehabilitation.

Interluekin-1 Family Members in COVID-19
Researchers will be collecting blood samples from Mary Free Bed patients who have/had a COVID-19 diagnosis. They will be assessing the inflammatory response associated with IL-1 and COVID-19.

Michigan Stroke Transitions Trial Inpatient to Community Feasibility Assessment (MISTIC)
The objective of this study is to improve transitional care for stroke survivors and their caregivers through development of a care transition program. This study assesses telehealth communication preferences and needs of stroke survivors and their caregivers during the transitional period, tests goal-setting procedures and evaluates the nature of the patient/care partner relationship and how it influences stroke survivor and caregiver interaction with the care transitions program.

Post-Treatment Patient Survey Comparison of Mary Free Bed Outpatient Therapy
Mary Free Bed is looking to compare results from different satisfaction surveys provided to those patients in Outpatient Therapy. These results will help make decisions when it comes to measuring post-contact patient response.
