About this study

Official title: Usability and Feasibility Study of Myosuit-based Gait Training for Ambulatory Neurological Patients With Gait Disorders

This study will investigate the safety and feasibility of over-ground training sessions with the Myosuit for the neurological inpatients of rehabilitation clinic Zihlschlacht with a gait disorder and their therapists. It will also examine the acceptability and motivation of patients and therapists to use the device for training in the clinical setting and at home or community level. Moreover, it will present first results of the training efficacy with the Myosuit in the inpatient setting on the mobility level of the International Classification of Function. The proposed trial is designed as an open-label, non-randomized interventional study

Read the detailed description

Neurological disorders are the leading cause of long-term disability in adults worldwide. The activity most affected by a neurological disease is walking. Gait disorders occur in approximately 60% of patients hospitalized for a neurological disease and are the first step toward immobility and loss of independence. Not reaching the walking speed, which is necessary to walk safely outside, hinders social (re)integration and the ability to participate in society. As a result, many neurological patients with gait disorders experience a significantly reduced health-related quality of life. Soft, lightweight wearable robots appear to be good candidates for supporting physical therapy in a clinical environment and improving functional mobility in outdoor settings and as assistive devices during activities of daily living within a home-based environment. The integration of these robots into home-based rehabilitation programs could greatly contribute to increasing the patient's activity level and social interaction, which increases the health-related quality of life in chronic neurological patients. The Investigators want to integrate this new form of therapy in the rehabilitation programme from inpatient to home setting with the aim of maintaining and/or improving patients' functional ambulatory ability and enable them to perform activities of daily living more independently. This research aims to evaluate the usability of the innovative wearable robot 'the Myosuit" and the feasibility of this new form of therapy in the inpatient setting. The investigators will also measure qualitatively and quantitatively the patients' motivation to want to continue using the device for the home training and the staff's motivation to recommend the training with this device in the home setting. Furthermore, the investigators will evaluate the staff's judgment on the feasibility of recommending the Myosuit for home-training.

In a time period of four weeks participants will undergo eight individual task-specific overground gait training sessions with the Myosuit.The inpatient training sessions will be started with a therapist, and if possible and as soon as possible, the patient will continue training with an assistant of therapy. Both therapists and assistants will be trained with the device before the study begins. The investigators introduce the training with assistants as an important step for transferring the inpatient training to the home setting where the relatives will assist the patients in the training with the Myosuit and they will have no background in physiotherapy as it is the case of the assistants in this study. The investigators assume that if the inpatient training is possible with therapists and subsequently with the assistants, it will be certainly feasible with the relatives.

For this study, the Myosuit (MyoSwiss AG, Zurich, Switzerland) will be used. The Myosuit is CE-Marked (Conformité Européenne; in accordance with European legislation), with reference number 1910001. The Myosuit is an untethered wearable robot designed to assist the essential mobility functions across activities of daily life, such as walking, standing, sitting, making transfers or climbing stairs. The Myosuit actively supports knee and hip extension in the early- to mid-stance phase of the gait cycle and passively aids hip flexion during swing, using elastic rubber bands

All the participants will be recruited from inpatients of Rehabilitation clinic Zihlschlacht by qualified (physio)therapists. The study participants will receive sufficient information about the study design and the risks and benefits of their participation. Patients have to meet defined physical requirements. To screen whether the patients meet these physical (manufacturer's recommendations) requirements, for the safety and feasibility of using the Myosuit, a clinical evaluation will be undertaken prior to the training period. In addition, to be included in the study, participants must meet the study inclusion and exclusion criteria It is planned to recruit 15 ambulatory neurological patients with gait disorder. The estimated duration is 5 months.

Mainly descriptive statistics will be performed in order to analyze the obtained data. Normal distribution will be determined visually by quantile-quantile plots and numerically by Shapiro-Wilk Normality Test. Matched-paired tests will be used to examine differences in pre-test and post-test scores. Associations between paired samples will be measured by either Spearman's rho or Pearson correlation coefficient depending on normality. Effect size will be calculated in order to measure meaningful differences between pre-test and post-test scores. A two-sided p value of <0.05 is considered statistically significant. All analyses are going to be performed using IBM® SPSS® Statistics and MATLAB and Statistics Toolbox, The MathWorks, Inc., Natick, Massachusetts, United States.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Myosuit-based gait trainingDevice

    In a period of four weeks participants will undergo eight individual task-specific overground gait training sessions with the Myosuit. The sessions will be started with a therapist, and if possible and as soon as possible, the patient will train with an assistant. During the therapy sessions, the patient will be asked to perform various task-specific exercises with the Myosuit, such as Sit-to-stand-, Balance- and walking exercises. Depending on the individual skill level of the participant, a higher level of difficulty in task-specific exercises can be performed. The training sessions are set to last 45 minutes. All training sessions will be accompanied by a certified (physio)therapist or trained assistant and a study investigator.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Usability of the Myosuit during task specific training

    The usability will be measured with the System Usability Scale (SUS). The SUS questionnaire will be completed by the participants, as well as therapists and therapy assistants. The SUS is an easy, valid and reliable tool for measuring the usability of a device. It consists of a 10-item questionnaire about the usability of a device with five response options for respondents; from strongly agree to strongly disagree. A score above 68 can be considered above average and anything below 68 is below average.

    Measured: 4 weeks

  2. Usability of the Myosuit during task specific training

    The usability will be measured with the Usefulness, Satisfaction, and Ease of use Questionnaire (USE). The USE questionnaire will be completed by the participants, as well as therapists and therapy assistants. The USE measures the subjective usability of a product or service. It is a 30-item questionnaire that examines four dimensions of usability: usability, ease of use, ease of learning, and satisfaction. a higher score indicates better usability.

    Measured: 4 weeks

  3. Safety of the Myosuit during task specific training.

    The safety will be analyzed by the risk of falling (near falls, falls and adverse events (AE)) and the change in walking speed, step length and cadence while performing the 10 Meter Walk Test (10MWT) with versus without the Myosuit.

    Measured: 4 weeks

Secondary outcomes (6)
  1. Motivation of patients to use the Myosuit during and after their inpatient rehabilitation

    The motivation will be measured by conducting an interview with the participants

    Measured: 4 weeks

  2. Motivation of therapists to use the Myosuit as a facilitator for gait training.

    The motivation will be measured by conducting an interview with the therapists

    Measured: 4 weeks

  3. Motivation of therapy assistants to use the Myosuit as a facilitator for gait training.

    The motivation will be measured by conducting an interview with the therapy assistants

    Measured: 4 weeks

  4. Efficacy of the four-week Myosuit-based gait training on mobility

    The mobility will be measured by the de Morton Mobility Index (DEMMI). The DEMMI is an assessment on an ordinal scale level, which can depict the mobility status of geriatric patients across the entire mobility spectrum by means of 15 items. It is hierarchically structured from easy to difficult. In five subcategories (bed, chair, static balance, walking, and dynamic balance) different activities are tested. Most items are rated with zero points or one point, depending on whether the activity can be performed (1) or not (0). For some items, a maximum of two points can be awarded in order to evaluate the level of support or the quantity of walking distance in a more differentiated way. The tester adds up the points to a raw score (max. 19 points) and converts this into the DEMMI score (0 to 100 points) for statistical reasons using a conversion table. In general, a higher score indicates better mobility.

    Measured: 4 weeks

  5. Efficacy of the four-week Myosuit-based gait training on walking speed

    The walking parameter walking speed will be measured by the 10-Meter Walk Test (10MWT). The 10MWT is a performance measure used to assess walking speed in meters per second over a short distance. Walking speed < 0.70 m/s is indicative of increased risk of adverse events (fall, hospitalisation, fracture, etc.). A speed <0.40 m/s indicates a household ambulator, a speed between 0.40 and 0.80 m/s indicates a limited community ambulator and speed > 0.80 m/s indicates the possibility of a community ambulator.

    Measured: 4 weeks

  6. Efficacy of the four-week Myosuit-based gait training on walking capacity

    The walking parameter walking capacity will be measured by the 6-Minute Walk Test (6MWT). The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity. An increase in the walked distance indicates improvement in basic mobility.

    Measured: 4 weeks
