Re-Step: Dynamic Balance Treatment of Gait for Acquired Brain Injury (ABI) Victims

Reuth Rehabilitation Hospital41 enrolled

Overview

The purpose of this study is to: 1. Test the walking functionality of people following Acquired brain injury (ABI) 2. Suggesting a new treatment for their walking impairments 3. Follow-up of motor learning ability and balance after intervention within this population The investigators intend to target dynamic stability and gait after ABI, in a group of individuals with ABI who have persistent balance and mobility deficits despite being able to walk independently and having high scores on standard clinical balance measures. Interventions: Training with Re-Step system shoes. In this study there is no control group.

Study design: Type of research: Prospective, exploratory, clinical, interventional trial Specific objectives are: To explore the efficacy of Re-step rehabilitation technology to improve dynamic balance in the gait of people after Acquired Brain Injury (ABI). The investigators suggest a new technology of intervention that will induce unexpected changes of underfoot slopes, with Re-Step shoes, during walking and will force the central nervous system (CNS) to react and solve walking problems in real-time. The investigators propose that the new approach will have a significant motor function improvement on balance in gait, transferred to real environmental settings and be retained for long periods of time. Research methods: Subjects: A total of 40 subjects of ABI victims will be studied in one treatment group-Re-Step shoes walking training Time flow protocol: Participants will be approached using a database of hospitalized patients of Reuth Rehabilitation Hospital (Tel-Aviv, Israel) and through a call for participation placed in a newspaper. Subjects will be recruited according to inclusion/exclusion criteria, after medical examination and given consent of participation. Tests and measures (see outcome measures) will be applied to measure changes: * T1 - before starting the intervention to form a baseline * T2 - after 20 sessions of intensive treatments 60 min each, 2 sessions a week. * T3 - 6 months after T2, a period of normal daily schedule of subjects, with no interventions, to examine for retainment of training results. The treatments will start in a week from T1; the T2 will be performed in a week after training was completed; T3 will be performed 6 months (take or leave 2 weeks) after T2.

Allocation

Interventions

Re-StepDEVICE

Research Group: Each session begins with a warm-up exercise, muscle stretching, and strengthening exercises: duration 10 minutes. Afterwards, walking exercises for 40 minutes with Re-Step according to a program individually tailored and progressing with the training. Progress is shown by an increased range of tilting of the shoe and speed of changes, according to the individual ability of each patient. At the end of the session 10 min of cool-down exercises 22 training sessions of 60 minutes each, twice a week.

Outcomes

Primary Outcomes

Community Balance & Mobility Scale (CB&M); Change from base line after intervention is being assessed

CB\&M was designed to evaluate balance and mobility in patients who, although ambulatory, have balance impairments that reduce their full engagement in community living. 13 items of dynamic balance are graded 0-5 by a physiotherapist. The CB\&M is a reliable and valid clinical outcome measure for evaluating change in ability in the higher functioning ambulatory patients with TBI.

Time frame: Measuring mobility ability and balance at base line and changes after intervention; and changes and rtainment of achievments 6 months of no intervention

Secondary Outcomes

10 Meter walk Test (10MWT)

Assesses walking speed in meters per second over a short duration. The individual is instructed to walk a set distance (6 meters, 10 meters, etc). Time is measured while the individual walks the set distance (often the individual is given space to accelerate to his/her preferred walking speed (this distance is not included when determining speed). The distance covered is divided by the time it took the individual to walk that distance.

Time frame: Measuring at base line; change immediately after intervention, and changes and retainments of achievments after 6 months

Montreal Cognitive Assessment (MoCA)

Widely used method for assessing cognitive mental status both in clinical practice and in research. It is a brief, standardized method to grade patients' cognitive mental status. It assesses orientation, attention, immediate and short-term recall, language, and the ability to follow simple verbal and written commands. It provides a total score that places the individual on a scale of cognitive function. The MoCA test has a high sensitivity for detecting cognitive dysfunction.

Time frame: Recruitment stage

fMRI functional magnetic Resonance Imaging; Change from base line after intervention is being assessed

Functional magnetic resonance imaging or functional MRI (fMRI) is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting associated changes in blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.

Time frame: Base line brain activity; change after treatment; and change after 6 months with no interventions
