Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants are assisted to transfer into the device, which is basically a pair of robot pants, and are then strapped into it. The intervention will involve 2 sessions of exercise therapy per week for 12 weeks. Each session will be 1 hour duration and will consist of individualised therapy, prescribed and administered by a Rex Robotic accredited physiotherapist. This will entail upright weight-bearing exercise facilitated by the device (HELLEN) as tolerated by the participant and will be a combination of sit to stand practise, standing tolerance, weight shift, trunk control exercises, stepping practise, side stepping, squats, upper limb exercises and gait practise. These exercises will be individually tailored to meet the abilities and needs of the client. Participants will also be provided with a short home exercise program (not in HELLEN) relevant to their treatment (requiring no more than half an hour per day), which will be reviewed and amended as required monthly during the therapy phase. Patients will be asked to self report participation in their home exercise program.
Interventions will only be progressed according to the individual participants’ abilities as deemed appropriate by the administering physiotherapist. Interventions will be modified or ceased if, in communication with the participant, the researchers deem that this is necessary.
Intervention code [1] 300799 0
Treatment: Devices
Comparator / control treatment
This trial has a 12 week observation period from week 0 to week 12 during which the participants will continue to receive their usual care. These are the same participants receiving the intervention from week 12. Intervention commences after the 12 week waiting period.

Usual care means that the participants are able to continue with their usual home exercise programs, sessions with health professionals and out-patient rehabilitation, exactly as they were prior to assessment.

Statistical methods / analysis
Descriptive statistics, including means and standard deviations (SD), will be calculated for demographic and outcome data. Change scores for each outcome from baseline will be tested using independent t tests for continuous variables and Chi square tests for categorical variables. Differences from enrolment, baseline, mid intervention, post intervention and 12-week follow up will be evaluated for statistical significance. All analyses will be conducted on an intention-to-treat basis, with missing follow-up data conservatively imputed using the last observation carried forward method.
