Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Body weight support treadmill training, 10 sessions (two sessions per week, 5 week duration, adherence monitoried at each session), 60 minutes per session. Sessions will be conducted by physiotherapists in one-on-one sessions. This technology includes mechanical assistance to facilitate limb movement (hip/knee flexion/extension), augmented reality (walking through a forest), visual feedback (for foot placement). Speed and body weight support will be set to individual appropriate levels as determined by the therapist. Minimum 5 week wash out between arms of the study.

Outcomes
Primary outcome [1] 334351 0
Feasibility determined against the below criteria
­1. Recruitment rates and willingness to participate (determined from recruitment log)
­2. Adherence to the treatment protocol (number of treatment sessions and average duration of each session). Will be determined agains attendance log.
­3. Acceptability and perceived helpfulness will be assessed on a 5-point Likert scales

Protocol will be considered feasible if >80% of potential participants are recruited, adherence >90% and program is considered acceptable/helpful, scoring at least 4/5 of the likert scales.

Eligibility
Key inclusion criteria
Participants will be eligible for inclusion if they are aged >18 years and have mobility impairments (defined as functional ambulation category of 0-4) following lower-limb amputation, brain or spinal cord injury.

Specific inclusion criteria for lower-limb amputees and people with spinal cord injury are: Amputees will be required to have a prosthesis (K-level 1 or 2, indicating a limited household, or limited community ambulator), people with spinal cord injury will be required to have an incomplete spinal cord injury and categorised as ASIA impairment scale C or D (i.e. some motor function preserved below the neurological level).
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria for all participants will be inability to follow two-step commands, travel to the treatment site, or pre-existing mobility impairments that are unrelated to the amputation, brain or spinal cord injury.

Safety/efficacy
Statistical methods / analysis
We will conduct a 2 GROUP (intervention, control) x 2 TIME-POINT (baseline, post treatment) linear mixed model for each outcome measure (physical activity, functional ambulation category, quality of life, gait speed). Where appropriate, post-hoc analysis with Bonferroni correction will be performed. Adverse events and falls diary data will be descriptively reported. Feasibility measures (recruitment rates, acceptability, perceived helpfulness, completed sessions and average duration) will be descriptively reported. In addition, acceptability and perceived helpfulness Likert scale scores, and both number and duration of sessions will be analysed with a 2 GROUP (intervention, control) x 3 CONDITION (lower-limb amputee, traumatic brain injury, spinal cord injury) linear mixed model. Qualitative interviews will be analysed and reported using thematic analysis.

Summary
Brief summary
We will conduct a pilot cross-over randomised controlled trial to assess feasibility of delivering mobility training using a gait rehabilitation technology. Upon enrolment, participants will be randomly allocated to the intervention or control group (1:1 ratio), before crossing over to the other arm of the trial. All treatments will be provided at the University of South Australia (UniSA) Health and Medical Clinic through a student led service, supervised by qualified clinicians.
