• Research summary

  Summary of Research
  Slider®, is a physiotherapy device to assist in the rehabilitation of patients needing knee replacements. This product connects to an accompanying mobile app to record when the patient is conducting their physiotherapy exercises and how often they are completing them. This can be fed back to the hospital to ensure the exercises are being completed correctly and that patients are compliant with the programme.
  We propose to conduct a usability study of the Slider® system with total knee replacement patients in the pre-operative stage. The patients will use the Slider® system for 2 weeks and perform the pre-operative exercises recommended by their clinical team. The patients will complete a post-study online usability questionnaire related to their experience of using the Slider® system.
  The goal of this study is to assess whether using Slider® in rehabilitative care for these patients pre-operatively, provides a satisfactory user experience to complete self-managed physiotherapy exercises out of a hospital setting, in free-living conditions. Answering this question, will determine the usability and acceptability of the Slider® system facilitating the establishment of the Slider® system as an effective tool for patients having knee replacements and who will necessarily require physiotherapy exercises that can be conducted out of a hospital environment.

  Summary of Results
  This RWV used a standard usability questionnaire to assess the Slider® system. The questionnaire evaluated five aspects of the system: Usefulness, Ease of use and learnability, Interface Quality, Reliability, Satisfaction and future use.
  The summary of key findings is given below:
  • A very high percentage of participants found the Slider® system useful for their pre-operative needs.
  • 73% of participants found the Slider® system easy to use and learn.
  • 80% of participants were pleased with the interface quality of the Slider® system.
  • A very high percentage of people, 93%, were satisfied, and all agreed they would use the system again.
  • 80% of participants found that when they made a mistake using the Slider® system they could recover easily and quickly

  This RWV concludes that the participants found the Slider® system useful, easy to use and learn. They were pleased with the interface quality, were satisfied with the system, and would use it again.
  This RWV has measured the usability and acceptability of the Slider® system. This RWV has established the Slider® system as an effective tool for patients having knee replacements to perform pre-operative physiotherapy exercises in a self-managed manner outside the hospital environment.
