Plain English summary of protocol
Background and study aims
Annually, 6,000 people in the UK are referred for fitting of an artificial lower leg (known as a prosthesis) after the surgical removal of their limb (lower-limb amputation). These are mostly patients over 50 years and usually have diabetes and/or blood vessel (vascular) problems. Older patients are often prescribed standard foot-ankle prostheses which are rigid at the “ankle”, unlike those often given to younger people which can adjust to slopes and stairs. It is unknown which is the best prosthesis for older patients. The aim of this study is to see whether it is possible to do a large study comparing the standard foot-ankle prosthesis to a new version, by first carrying out a smaller study.
Who can participate?
Patients aged over 50 with a below-knee amputation because of vascular problems and who find walking difficult
What does the study involve?
Participants are randomly allocated into one of two groups to wear either their existing prosthesis or a new prosthesis for 12 weeks. One-to-one interviews are held to ask patients how they felt about participating in the study. The researchers measure how far patients can walk, how long they wear their prosthesis daily, and ask them to score their pain, health and well-being. This is done with questionnaires, simple exercise tests and a wearable device which measures activity.
What are the possible benefits and risks of participating?
Participants may not directly benefit from this study but taking part could help build up the evidence about how beneficial the new prosthesis is compared to standard prostheses. No risks are expected, but participants in the new prosthesis group may find that it can take them some time to adjust to the new prosthetic, therefore they could slip or stumble as they adjust to it.
Where is the study run from?
1. Hull & East Yorkshire NHS Trust (UK)
2. Nottingham University Hospitals NHS Trust (UK)
When is the study starting and how long is it expected to run for?
April 2018 to March 2020
Who is funding the study?
National Institute for Health Research (NIHR) (UK)

| Scientific title | STEPFORWARD: Patient acceptability of a novel prosthetic device: a randomised feasibility study in older patients with vascular-related amputations and multimorbidities |
| Study acronym | STEPFORWARD |
| Study objectives | To assess the feasibility of conducting a future, full scale randomised controlled trial into the effectiveness and cost-effectiveness of a novel prosthesis for older patients with vascular-related amputations and other health issues compared to a standard prosthesis. |
| Ethics approval(s) | Yorkshire & the Humber - Leeds West, 09/03/2018, ref: 18/YH/0089 |
| Health condition(s) or problem(s) studied | Disorder of arteries and arterioles, unspecified |
| Intervention | Multi-centre, randomised controlled, open feasibility study, using a 1:1 randomisation ratio, patients will be block randomised, stratified by prosthetics centre. The study will look at the randomisation process, recruitment and whether patients found the study processes acceptable. Over two years, the trialists want to recruit 90 older people with a below-knee amputation because of vascular problems and who find walking difficult. They will invite patients from three prosthetics centres across England to participate and they will be placed randomly into one of two groups by a computer: wearing 1) their existing prosthesis or 2) a new prosthesis for 12 weeks. There will be one-to-one interviews to ask how patients felt about participating in the study. The trialists will measure how far patients can walk, how long they wear their prosthesis daily, and ask them to score their pain, health and well-being. They will do this with questionnaires, simple exercise tests and a wearable device which measures activity. |
| Intervention type | Other |
| Primary outcome measure | The feasibility of conducting a future, full scale RCT into the effectiveness and cost-effectiveness of a novel prosthesis for older patients with vascular-related amputations and other health issues compared to a standard rigid prosthesis. This will be assessed based on whether: 1. Study consent/retention rates and proposed sample sizes indicate recruitment for the full-scale RCT is plausible within a 24-month period 2. Outcome measures and fidelity evaluation data are successfully collected 3. There are no significant barriers to delivery of the trial identified by participants or recruiting centres |
| Secondary outcome measures | 1. Patient recruitment rate 2. Barriers to recruitment, how these might be overcome from the perspective of patients, and the most important outcomes to them 3. The acceptability of the study procedures to both participants and recruiting centres 4. Patient use of NHS resources over the study period related to the research 5. Identify a primary outcome measure(s) for a future main trial (if feasibility is established) 6. The completeness of follow-up to establish how feasible it is to collect patient-reported outcome measures including data related to patient function, health status, adverse events and use of the NHS 7. Day-to-day use of the prosthesis in both groups and measure normal physical activity through the use of wearable technologies (activity monitors) |
