简要总结

The goal of this randomised controlled feasibility trial is to find out whether it is possible to run a larger study of the Good Boost+ community based rehabilitation programme for people waiting for a primary total knee replacement.

The study will look at how many people are willing to take part, whether they stay in the study, and whether they can follow the Good Boost+ programme as planned. It will also explore how acceptable the programme is to patients, NHS staff and leisure centre staff, and which outcome measures are most useful for a future full scale trial. The study will also look at what helps or hinders delivery of the programme in real world NHS and community settings.

The main questions it aims to answer are:

  • How many people waiting for knee replacement surgery are willing to take part in the study
  • Whether participants can continue with the Good Boost+ programme as planned over the study period
  • Which outcome measures best capture any potential benefits of the programme
  • How acceptable the programme is to patients, NHS and leisure centre staff
  • What helps or makes it difficult to deliver the programme in practice.

Participants will be randomly assigned to one of two groups.

  • Usual NHS care or
  • Usual NHS care plus the Good Boost+ programme

Participants in the Good Boost+ programme will take part in six weekly group water based exercise sessions held in local swimming pools, as well as land based exercise sessions that can be done individually or by joining a virtual group. The exercise sessions are delivered through Good Boost's digital technology, using small waterproof tablet computers at swimming pools, and smartphones or computers for land-based sessions. Physiotherapy staff will provide guidance throughout, and volunteers will offer refreshments after pool sessions to support social connection.

All participants, including those receiving usual NHS care only, will be asked to complete an exercise diary, rate their knee pain each week, and complete short questionnaires at 6 and 10 weeks after joining the study.

详细描述

Knee replacement surgery can greatly reduce pain and improve mobility for people with severe knee arthritis. However, NHS waiting times for surgery are often long, and many people experience worsening pain, reduced ability to work or take part in daily activities, low mood, and increased reliance on strong painkillers while they wait. These challenges can also affect recovery after surgery. Exercise programmes undertaken before surgery, known as 'prehabilitation', may help people feel better during the waiting period and may support better outcomes after surgery. Despite this potential, prehabilitation programmes are not widely available across the UK, and existing provision varies depending on where people live.

There is currently limited evidence about how best to deliver prehabilitation in a way that people waiting for orthopaedic surgery find acceptable, practical, and motivating. It is not yet clear which types of programmes people are most likely to use and stick with while waiting for knee replacement surgery. The Good Boost+ programme offers an approach that combines water-based group exercise in local swimming pools with flexible land-based exercise that can be completed individually or by joining a virtual group. The programme uses digital technology, and pool-based sessions are delivered in community leisure facilities rather than hospital settings. Exercising in water may be more comfortable for people with knee pain, and group sessions supported by refreshments afterwards provide opportunities for social interaction and peer support.

Early pilot work suggests this approach may be promising, but more evidence is needed to understand whether people awaiting knee replacement surgery are willing and able to take part, attend regularly, and complete the programme as intended when delivered alongside usual NHS care. With increasing demand for knee replacement surgery and long waiting times placing strain on patients and the NHS, there is an urgent need to explore new ways of supporting people during the waiting period.

This study is a two arm, parallel group, randomised controlled feasibility trial implementing the Good Boost+ programme for adults awaiting primary total knee replacement. An embedded mixed methods study will explore the acceptability of the intervention and identify determinants influencing the implementation of Good Boost+. The investigators aim to recruit 48 participants from orthopaedic services at NHS Trusts in South London. Participants will be randomly allocated in a 1:1 ratio to receive either usual NHS pre operative care alone or usual NHS pre operative care plus the Good Boost+ programme.

Participants allocated to the intervention group will receive usual NHS care plus the Good Boost+ programme. This includes an initial assessment and goal setting session with an NHS physiotherapist; six weekly group based water exercise sessions delivered in a leisure centre swimming pool using the Good Boost HUB app on a waterproof tablet computer; three home-based land exercise sessions per week using the Good Boost Move Together app on a smartphone or tablet computer; and weekly one to one support sessions with a physiotherapist delivered remotely. Following aquatic sessions, refreshments will be provided to encourage informal peer support. Participants in the control group will continue with usual NHS pre operative care.

  • •Access to a smart phone or tablet computer with internet access. Willing and able to accept either trial arm allocation. Willing and able to give informed consent.

排除标准

  • •Individuals scheduled to have another major joint replacement (e.g. contralateral knee, hip or shoulder) within the study period.
