Inpatient Stroke Recovery Using Sensors
Wearable Sensor Platform to Monitor Stroke Recovery During Inpatient Rehabilitation
Study Overview
Detailed Description
OBJECTIVES:
Aim 1: Assess the feasibility of continuous long-term monitoring of inpatients with stroke using wearable sensors.
The investigators will obtain quantitative health data from research-grade, wireless, wearable sensors on individuals with subacute and chronic stroke in the clinical setting, as well as healthy controls.
The investigators will specifically check for variability in device data, as well as consistency and periodicity of sensor readings across the clinical study period. The investigators will analyze test-retest reliability and inter-rater reliability of using the wearable sensor technology for clinical and monitoring applications. Furthermore, The investigators will determine whether the sensors can distinguish biometric and activity characteristics between healthy controls and individuals with stroke.
Aim 2: Quantify upper and lower extremity movement impairments, mobility-related activities, speech and swallowing activities, and clinical parameters during stroke recovery.
The investigators will obtain continuous biometric and movement-based sensor data for clinical symptoms (e.g., muscle activation, heart rate variability, talk time, and gait quality) during the performance of validated clinical tests and during general inpatient activities (e.g., therapy, eating, and sleeping).
The investigators will compare device data with clinically validated measures of movement and language function, such as the Modified Ashworth Scale or Western Aphasia Battery. The investigators will describe variation of device data in subgroups of subjects defined by clinician assessed clinically validated measures (10-Meter Walk Test, Mini-Mental Status Exam, etc.). The investigators will also assess the ability of the sensors to capture response to treatment, such as movement therapy, speech therapy, medication, and Botox by comparing sensor data before and after treatment. The investigators will provide evidence about the degree to which the measured variables are intercorrelated. Lastly, The investigators will evaluate and compare the state of recovery between patients at time of discharge using sensor-based outcomes. Due to heterogeneity of clinical symptoms after stroke, as differing etiologies and degrees of recovery result in different types and levels of gait impairments, preliminary analyses may be performed on specific sub-datasets to determine which predictors, data types, and other data compositions affect algorithm performance before their application and evaluation on the dataset collected at the end of this study. Sub-datasets may be sampled based on (but not limited to) the population characteristics, the sensors used, the data available at the time analysis.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Discharge clinical scores estimation
Time Frame: Discharge from inpatient stay. Average length of stay is 22 days.
|
Error between clinical scores estimated from machine learning algorithms trained on sensor data from the Admission time-point, and true scores assessed at the discharge from the hospital.
|
Discharge from inpatient stay. Average length of stay is 22 days.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in 6-Minute Walk Test (6MWT)
Time Frame: From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
The 6MWT measures the distance a subject can walk indoors on a flat, hard surface in 6 minutes, using assistive devices as necessary.
The test is a reliable and valid evaluation of functional exercise capacity and is used as a sub-maximal test of aerobic capacity and endurance.
The minimal detectable change for people with sub-acute stroke is 60.98 meters.
Wearable sensors are used to monitor the movement of the subject during the test.
|
From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
Change in 10-Meter Walk Test (10MWT)
Time Frame: From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
The 10MWT measures the amount of time it takes to walk 10 meters.
Time will be recorded using a stopwatch and recorded to the one hundredth of a second.
The effects of acceleration and deceleration are minimized by adding 1 meter at the beginning and end of the course to isolate the subject's steady state speed.
The test will be recorded 3 times each at a normal self-selected pace and at a faster pace, with adequate rest in between.
Results will be averaged from 3 trials.
Any assistive devices or orthotics should be kept consistent throughout and documented.
Wearable sensors are used to monitor the movement of the subject during the test.
|
From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
Change in Berg Balance Scale (BBS)
Time Frame: From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
The BBS is a 14-item test, scored on a 5-level ordinal scale and validated against length of stay and discharge destination for stroke patients.
The total score is expressed as a number between 0 and 56, where lower score mean increased balance impairment.
It measures functional balance in a clinical setting during static and dynamic tasks (sitting, standing, transitioning from sit to stand, etc.).
Wearable sensors are used to monitor the movement of the subject during the test.
|
From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
Change in Timed Up and Go (TUG)
Time Frame: From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
The TUG assesses mobility by measuring the time a person take to rise from a chair, walk 3 meters, turn around, walk back to the chair, and sit down.
It can detect longitudinal changes in mobility in stroke patients.
The subject wears their routine footwear and orthotics and can use their mobility aids.
Wearable sensors are used to monitor the movement of the subject during the test.
|
From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
Change in Functional Gait Assessment (FGA)
Time Frame: From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
The FGA is comprised of 10-item that contains 7 of 8 items (except walking around obstacles) from the Dynamic Gait Index and 3 additional tasks, including walking with a narrow base of support, walking with the eyes closed, and walking backward.
Subjects' performance of each test item was rated on a 4-point scale (0-3), with the total score ranging between 0 and 30.
Wearable sensors are used to monitor the movement of the subject during the test.
|
From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
Change in Gait Analysis
Time Frame: From Admission time-point to 1-2 weeks, 1 month, 3 months, 6 months, 12 months post-stroke
|
Gait analysis provides a quantitative means of assessing walking function based on spatiotemporal parameters of gait.
Subjects walk at both a comfortable and a fast pace over the GaitRite system, an electronic walkway with integrated sensors.
Data from GaitRite is reliable and valid for evaluating walking characteristics and provides a gold standard for validating gait parameters from the sensors.
Wearable sensors are used to monitor the movement of the subject during the test.
