Stroke Clinical Trial
Official title:
Comparison of Intensity and Step Count of Gait Training Modalities in the Inpatient Rehabilitation Setting in Sub-acute Central Nervous System Injury
The purpose of the project is to compare intensity (minutes in target heart rate zone) and steps per session across three gait training modalities, including body-weight supported treadmill training (BWSTT), overground gait training with body weight-support (BWS), and overground gait training utilizing a lower extremity exoskeleton, between patients presenting with varying functional ambulation capacities in the inpatient setting. Additionally, the researchers will compare physical therapist (PT) burden across these modalities and patient functional presentation levels.

Primary | Observation of Step count | The number of steps taken during each session will be measured using activity monitors/pedometers. These devices are small accelerometers that can be worn on a belt and/or on the ankle to record steps and Kcals during an activity. The therapist leading the intervention session will apply the ActiGraph at the beginning of each intervention session and remove it upon completion. A higher step count is a better outcome. | Each session through completion of study, up to 10 days | |
Primary | Observation of Time spent in age-predicted maximum high-intensity target heart rate zone | The target range of 70-85% of age-predicted maximum heart rate will be calculated for each participant utilizing HR max = 208 - [0.7 × age] as developed by Tanka et al in 2001. The target range of 70-85% of age-predicted maximum heart rate will be calculated for each participant. The researchers will record the amount of time participants spend in their pre-calculated target zone during each gait training. The minimum amount of time would be 0 minutes and the maximum amount of time would be 60 minutes as this would be the total time of the session. More time spent in the maximum intensity zone target zone is a better outcome. | Each session through completion of study, up to 10 days | |
Primary | Observation of Time spent in age-predicted moderate-intensity target heart rate zone | The target range of 50-70% of age-predicted maximum heart rate will be calculated for each participant utilizing HR max = 208 - [0.7 × age] as developed by Tanka et al in 2001. The target range of 50-70% of age-predicted maximum heart rate will be calculated for each participant. The researchers will record the amount of time participants spend in their pre-calculated target zone during each gait training. The minimum amount of time would be 0 minutes and the maximum amount of time would be 60 minutes as this would be the total time of the session. Less time spent in the moderate intensity pre-calculated target zone is a better outcome as the more minutes in the high intensity zone is the best outcome. | Each session through completion of study, up to 10 days | |
Primary | Observation of Time spent in age-predicted low-intensity target heart rate zone | The target range of 50% of age-predicted maximum heart rate will be calculated for each participant utilizing HR max = 208 - [0.7 × age] as developed by Tanka et al in 2001. Low intensity equals 50% or less of age-predicted maximum heart rate and will be calculated for each participant. The researchers will record the amount of time participants spend in their pre-calculated target zone during each gait training. The minimum amount of time would be 0 minutes and the maximum amount of time would be 60 minutes as this would be the total time of the session. Less time spent in the low intensity zone is better as the goal is to achieve more minutes in high-intensity zone. | Each session through completion of study, up to 10 days | |
Secondary | Observation of Minutes spent in equipment setup per session | Total time in minutes spent applying and removing equipment. The minimum amount of time would be 0 minutes and the maximum amount of time would be 60 minutes as this would be the total time of the session. Less time would be considered better as that indicates more time spent walking. | Each session through completion of study, up to 10 days | |
Secondary | Observation of Minutes spent in rest breaks per session | Total time in minutes the participant spends resting (not walking or applying/ removing equipment) between walking bouts. The minimum amount of time would be 0 minutes and the maximum amount of time would be 60 minutes as this would be the total time of the session. Less time would be considered better as that indicates more time spent walking. | Each session through completion of study, up to 10 days | |
Secondary | Observation of Minutes spent stepping | Total time in minutes the participant spends walking (not including rest breaks or applying/ removing equipment) during a session. The minimum amount of time would be 0 minutes and the maximum amount of time would be 60 minutes as this would be the total time of the session. Less time would be considered better as that indicates more time spent walking. | Each session through completion of study, up to 10 days | |
Secondary | Observation of Patient Borg Rating of perceived exertion (RPE) | The Borg Rating of Perceived Exertion is a tool to measure the subjective report of effort, exertion, and fatigue during physical work. It consists of a 15-point scale from 6-20, in which 6=no exertion and 20=absolute maximum exertion. It is presented to the participant in written format with descriptors to standardize the report of perceived exertion across tasks. An optimal score is between 14-20 as this indicates higher perceived walking intensity for the participant. | Each session through completion of study, up to 10 days | |
Secondary | Observation of Patient Intrinsic Motivation Inventory (IMI) | The Intrinsic Motivation Inventory (IMI) is a multidimensional measurement that measures participants' subjective experience related to a target activity in laboratory experiments. The instrument consists of seven subscale scores related to interest/enjoyment, perceived competence, effort/importance, felt pressure/tension, perceived choice, value/usefulness and relatedness while performing a given activity. 29 items, adapted from the standardized instrument, are addressed on a 7 point scale, 1-7, in which one indicates not at all and seven indicates very true. A higher score is better. | Each session through completion of study, up to 10 days | |
Secondary | Observation of therapist maximum heart rate | Therapist heart rate will be measured throughout each session as an indicator of burden. There is no standard minimum or maximum value, however a higher heart rate indicates increased therapist burden. | Each session through completion of study, up to 10 days | |
Secondary | Observation of therapist maximum Borg Rating of perceived exertion (RPE) | The Borg Rating of Perceived Exertion is a tool to measure the subjective report of effort, exertion, and fatigue during physical work. It consists of a 15-point scale from 6-20, in which 6=no exertion and 20=absolute maximum exertion. It is presented to the participant in written format with descriptors to standardize the report of perceived exertion across tasks. A lower score is better, indicating less burden on the therapist. | Each session through completion of study, up to 10 days | |
Secondary | Observation of therapist Numerical Pain Rating Scale (NPRS) | The NPRS is used to measure the subjective report of pain intensity. It consists of an 11-point scale, 0-10, in which zero indicates no pain and ten indicates the most intense pain imaginable. A lower score is better, indicating less pain. | Each session through completion of study, up to 10 days |
