Bed Bridge Test in Acute Stroke Patients

Studies examining the validity and reliability of easy-to-apply muscle strength and mobility outcome measures in the acute and subacute phases of stroke are quite limited. Therefore, the purpose of this study was to investigate whether the In-Bed Bridge Test is a useful outcome measure for assessing lower extremity muscle strength and mobility in stroke.

About this study

Stroke is defined as an acute neurological dysfunction of vascular origin, with symptoms varying depending on the affected brain regions. Stroke patients often experience spasticity, upper and lower extremity dysfunction, mobility loss, and problems with walking, swallowing, vision, and communication, which span multiple systems and impact an individual's functionality. Assessing functional mobility and muscle strength plays a crucial role in planning a stroke patient's treatment program and demonstrating treatment effectiveness. Studies examining the validity and reliability of easily administered muscle strength and mobility outcome measures in the acute and subacute stages of stroke are relatively few. Therefore, the purpose of this study was to investigate whether the In-Bed Bridge Test is a useful outcome measure for assessing lower extremity muscle strength and mobility in stroke.

Primary outcomes

Bed Bridge Test

Time frame: At baseline and second day

The bed bridge test is performed on a bed or stretcher with a zero-degree headrest. The upper extremity is extended parallel to the trunk. The knees and hips are flexed at 45° and 60°, respectively, and measured and controlled with a goniometer. The in-bed bridge test is performed in four different ways: two with a limited number of repetitions (5 and 10) and two with a time limit (30 and 60 s). For the 5 and 10 repetitions limited versions of the in-bed bridge, participants are asked to perform 5 and 10 repetitions as quickly as possible, and the time required to complete each repetition is recorded. For the time-limited version of the bed bridge pose, participants are asked to complete as many repetitions as possible within 30 and 60 seconds, and the number of repetitions is recorded.
Short Physical Performance Battery Test

Time frame: At baseline
It consists of three objective tests that assess lower body function. These are: the 4-meter walk test, the chair-to-stand test, and the standing balance test. A 5-level summary score (0-4) is assigned to each test. A score of zero indicates "Unable to perform." Participants included in the "Unable to perform" category were:
- Those who attempted but were unable to perform the activity,
- The interviewer or the subject felt unsafe,
- Those unable to perform the activity due to other health reasons.
The National Institutes of Health Stroke Scale (NIHSS)

Time frame: At baseline

The National Institutes of Health Stroke Scale (NIHSS), consisting of 11 basic scales based on physical examination findings, was developed to determine stroke severity. This scoring system provides insight into patient prognosis and response to treatment.An increase in the score indicates an increase in stroke severity.
Fugl-Meyer Rating Scale

Time frame: At baseline

The Fugl-Meyer Rating Scale (FMRS) will be used to assess lower extremity motor function. This scale was developed to assess a patient's sensorimotor recovery after stroke according to the Brunnstrom stages of motor recovery. It consists of five sections: motor function (upper and lower extremities), sensation, balance, range of motion, and joint pain. In our study, the lower extremity assessment section will be used. The total possible score for the lower extremity is 34. The higher the score, the better the performance. Each parameter is scored as 0: Failure, 1: Partially Successful, and 2: Completely Successful.
Sit-to-Stand Test

Time frame: At baseline

This test is used to assess the patient's functional status. The participant is asked to sit with their feet flat on a standard chair, 43-46 cm high, with no armrests and a backrest. The participant is asked to stand up from the chair and sit down again for one minute, arms crossed in front of the chest. The total number of sit-ups completed constitutes the total score.
