Effectiveness of Using a Chatbot to Promote Adherence to Home Physiotherapy

Study Overview
=================
Brief Summary
-----------------
A Chatbot oriented to virtually assist patients in a physiotherapy treatment has been designed and developed to interact with patients with musculoskeletal disorders in need for domiciliary rehabilitation. The tool has been designed to promote adherence to rehabilitation, what in turn may have an impact on clinical outcome. A randomized clinical trial involving patients undergoing total knee replacement has bee designed to determine the applicability of the proposal. The participants will be assigned into exerimental group (intervention with the software tool) or control group (standard care).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adherence | Compliance with intervention measured as the percentage of sessions carried out with respect to the total planned | Change from baseline to 3 months after surgery date | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) | Self-administered questionnaire consisting of 24 items divided into pain, stiffness and physical function will register self-reported status. The score is given from 0 to 100 | Change from baseline to 3 months and one year after surgery date | 
| Knee Pain | Measured with a visual analogue scale of pain, being 0 no pain and 10 the worst possible pain | Change from baseline to 3 months and one year after surgery date |
