Participant Information Sheet Study title: Rex robot Assisted rehabilitation exercise to enhance balance, mobility and uPPER limb function in people with Multiple Sclerosis "RAPPER III - MS" Rex Bionics are now enrolling for RAPPER III, a 10 patient trial at East Kent University Hospital foundation Trust. The study will take place at the following address: School Of Engineering and Arts, Jennison Building, University of Kent, Canterbury CT2 7NT We would like to invite you to take part in our research study. Before you decide we would like you to understand why the research is being done and what it would involve for you. One of our team will go through the information sheet with you and answer any questions you have. The objective of this feasibility study is to evaluate the overall device safety when used in a Clinical Rehabilitation Centre under the supervision of a physician and/or qualified rehabilitation specialist. The trial can be completed by patients over 6 sessions, each a week apart. The study will consist of walking in REX Bionics powered exercise device and completing a variety of therapy exercises the assistance of REX trained therapists. You will be asked to complete some questionnaires and other tests before the first session, after the 3rd session and finally after your 6th session. This document is broken into 2 parts Part 1 - tells you the purpose of this study and what to expect if you take part. Part 2 - gives you more detailed information about the conduct of the study. Part 1 What is the purpose of this study? i) To assess the feasibility and safety of undertaking a neuro-rehabilitation exercise program using a Rex robotic device within a controlled clinical environment (ease of use for both user and therapist ii) Investigate the potential to improve balance and walking using Rex for people with MS iii) Investigate the potential health benefits of this Rex Rehabilitation program iv) Ascertain whether there might be a measurable impact on upper limb functional abilities Why have I been invited? You have been asked to participate in this study because you have a diagnosis of multiple sclerosis that fits the inclusion criteria of this study. There will be a number of assessments prior to trialling the device to ensure you fit the criteria to safely use REX. This is for your own safety. Do I have to take part? It is up to you to decide to join the study. We will describe the study and go through the information sheet. If you agree to take part, we will then ask you sign a consent form. You are free to withdraw at any time, without giving a reason. This would not affect the standard of care you receive. We are planning to enrol 10 people for this study. What will happen to me if I take part? Study Schedule You will be asked to come to the rehab clinic for 6 sessions. The timing of these sessions vary and more detail is given below. Each session will be a week apart. Please ensure you wear supportive fitting laced shoes, a pair of comfortable sporting trousers/track suit bottoms and a light T-Shirt or Similar. If you have issues with the support structures of your feet you should consider using orthotics to offer added support. Please raise any concerns you have with your therapist conducting the research so further information can be provided to you. Enrolment - You will be asked some screening questions prior being enrolled in the study. If you are enrolled, you will be asked to complete 13 outcome measures (tests/questionnaires) in session 1, 4 questionnaires 2 days after session 3 and finally all 13 outcome measures (tests/questionnaires) in session 6. (approximately 90 minutes) Session 1 - you will be asked to come into the clinic to complete a number of tasks. (approximately 150 minutes) Task 1: baseline medical assessment and giving informed consent: A medical examination will take place along with a discussion around your current medical conditions and previous medical conditions to determine if you are safe to use REX. You will be given a patient information sheet and ask to give consent if you would like to be included in the study. You can withdraw at any time and do not have to give consent if you do not choose to. Task 2: Assessment against inclusion criteria: You will be assessed against a number of different inclusion and exclusion criteria to determine whether you are appropriate for the study Task 3: completion of pre-treatment outcome measures and questionnaires: You will be asked to complete a number of scales and questionnaires. These will be repeated at the end of the study (during sessions 6). If you have any questions about any of these you should ask the investigator and the investigator will provide you with enough time and space to discuss everything. The outcome measures are listed below. Activities-specific Balance Confidence (ABC) Scale Modified Falls Efficacy Scale (MFES) Multiple Sclerosis Walking scale (MSWS-12) Multiple Sclerosis Impact scale (MSIS-29) ARMA (arm activity measure) Berg Balance Scale Video of sit to stand and stand to sit (recorded twice ) Video of walking - timed up and go (3 metres ) Pain scale questionnaire (Visual Analog Score VAS) Modified Ashworth Score Epworth Sleepiness Scale (ESS) questionnaire EQ-5D Health State Questionnaire Task 4: Measurements, fitment and mobilizing A number of measurements will be taken to ensure you can safely use and fit the device Once these have been taken you will be asked to transfer into the device. This will be timed. On completion of a safe transfer you will be asked to stand up in Rex and walk 3 m, turn around and come back again, then sit back down on the chair. This will be timed. Task 5: Exercise prescription The investigator will work with you to determine an appropriate amount of weights/resistance that should be used for your treatment programs in the subsequent session. Session 2: Completion of a prescribed exercise program. (approximately 45 minutes) Task 1: You will be asked to complete a set number of exercises that should last approximately 45 minutes. Session 3: completion of a prescribed exercise program. (approximately 45 minutes) Task Task 2: You will be asked to complete 3 questionnaires 2 days (plus or minus one day for flexibility with your schedule) after your exercise program. These will be completed over the phone with the investigator conducting the study. You will be given an envelope with all the questionnaires in so you have a point of reference. These questionnaires will be: Pain scale questionnaire (Visual Analog Score VAS) Epworth Sleepiness Scale (ESS) questionnaire You will also be assessed for your level of spasticity using the Modified Ashworth Score Session 4: Completion of a prescribed exercise program. (approximately 60 minutes) Task 1: you will be asked to complete a set number of exercises as you did in the previous sessions Session 5: completion of a prescribed exercise program. (approximately 60 minutes) Task 1: you will be asked to complete a set number of exercises as you did in your previous sessions Task 2: You will be asked to complete a timed transfer to see if it has got any quicker since your first session. Session 6: Completion of follow up outcome measures and questionnaires. (approximately 90 minutes) Task 1: You will be asked to complete all the same scales and questionnaires you completed in session 1 to see if there has been any improvement. If you are unable to make the appointed visits in the time frame above, you will need to notify your physician or rehabilitation therapist.
