Conditions

Interventions
Behavioral: High intensity gait training
Registration Number
NCT06373107
Lead Sponsor
Alvernia University
Brief Summary

The purpose of this research is to study the improvements from walking practice that is vigorous enough to keep participants' heart rate over a certain target level during their physical therapy sessions. The investigators want to know about improvements in participants' walking function and mental health after 20 interventions. The study also aims to evaluate if participants' mental health, social support, and health literacy affect their attendance at physical therapy sessions.

Detailed Description

The purpose of this research is to study the improvements from walking practice that is vigorous enough to keep participants' heart rate over a certain target level during their physical therapy sessions. The investigators want to know about improvement in participants' walking function and mental health after 20 interventions. The study also aims to evaluate if participants' mental health, social support, and health literacy affect their attendance at physical therapy sessions.

The findings from this study will help the researchers and clinicians decide how to help people with stroke better. Further, the findings will determine how depressive symptoms, health literacy, and other factors such as language and education affect attendance to therapy.

About 24 subjects will take part in this research.

Primary Outcome Measures
NameTimeMethod
6-minute walk testPre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

Measures aerobic capacity and endurance

Berg Balance ScalePre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

a 14-item objective measure that assesses static balance and fall risk in adults. Berg balance scale scoring ranges from 0 to 56, with higher scores mean a better outcome.

Multidimensional Scale of Perceived Social Support (MSPSS)Pre-intervention (baseline)

The MSPSS is a 12-item self-administered scale that measures social support. It contains 12-items, rated on a 7-point Likert-type scale, ranging from 1 "very strongly disagree" to 7 "very strongly agree." The scale was divided into 3 subscales: family, friends, and significant other, with each section consisting of 4 items. The response scale ranges from 12 to 84. Higher scores indicate a greater family social support.

Rate of patient attendance (Compliance) to physical therapyParticipant's attendance to physical therapy is tracked throughout the intervention sessions.

Greater than or equal to 80% attendance to physical therapy is considered compliance to physical therapy.

10-meter walk testPre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

Measures forward gait velocity

Functional Gait AssessmentPre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

This scale assess postural stability during walking and assesses an individual's ability to perform multiple motor tasks while walking. Scoring for each FGA item ranges from 0 for severe impairment to 3 for normal performance. The highest score possible is 30, with higher scores correlating better gait function.

3-meter backwards walk testPre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

Measures backward gait velocity

Surface electromyography (EMG)Pre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

Electromyographical recording of 8 leg muscles () is done during forward and backward walking tests.The EMG will be recorded during 3-meter Backward Walk Test, 6-minute Walk Test, and 10-meter Walk Test in all participants

Borg Rating Scale of Perceived Exertion (RPE)Pre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

RPE is used to prescribe and monitor exercise intensity and correlates well with physiological measures of exercise intensity, including heart rate. The Borg Rating Scale of Perceived Exertion will be measured in all participants at the completion of 6 Minute Walk test. It ranges from 6 to 20, where 6 means "no exertion at all" and 20 means "maximal exertion." A lower score indicates a better exercise endurance.

Patient Health Questionnaire (PHQ-9)Pre-, mid- (week 5) and post-intervention (within 2 weeks after the conclusion of intervention)

Depressive symptom questionnaire. As a severity measure, the PHQ-9 score can range from 0 to 27, since each of the 9 items can be scored from 0 (not at all) to 3 (nearly every day). A lower score indicates less depressive symptoms.

Newest Vital SignPre-intervention (baseline)

The NVS is a 6-question screening tool that identifies participants' risk of low or limited health literacy based on interpreting an ice cream nutrition label. It is available from Pfizer Pharmaceutical Company. The level of health literacy for each individual will be categorized based on the scores: a score of 0-1 suggests a high likelihood of limited literacy, a score of 2-3 indicates the possibility of limited literacy, and a score of 4-6 almost always indicates adequate literacy. This categorical variable will be used to determine the association with adherence to physical therapy.
