Brief Summary

Rehabilitation, with a particular emphasis on physiotherapy and exercise, is widely promoted and strongly recommended after total knee replacement (TKR). The primary goals of rehabilitation are to improve knee range-of-motion, muscle strength, functional mobility and perceived quality of life. Exercises are usually prescribed and guided by a physiotherapist attending to the patient. The intensity of rehabilitation has an impact on clinical outcome. A study done by Lee et al in 2012 concluded that higher exercise dose translates to better function after TKR, especially in older population and for those with higher pain. Various literatures has also strongly recommended twice a day rehabilitation session for patients after TKR (Cook et al, 2008; Smith et al 2012).

Detailed Description

Rehabilitation, with a particular emphasis on physiotherapy and exercise, is widely promoted and strongly recommended after total knee replacement (TKR). The primary goals of rehabilitation are to improve knee range-of-motion, muscle strength, functional mobility and perceived quality of life. Exercises are usually prescribed and guided by a physiotherapist attending to the patient. The intensity of rehabilitation has an impact on clinical outcome. A study done by Lee et al in 2012 concluded that higher exercise dose translates to better function after TKR, especially in older population and for those with higher pain. Various literatures has also strongly recommended twice a day rehabilitation session for patients after TKR (Cook et al, 2008; Smith et al 2012). The standard practice in the in-patient setting is that physiotherapist will attend to the TKR patients once a day and remind patients to perform exercises by themselves, following the exercise booklet given, during their free time in the ward to maximise their recovery. However, due to post-operative fatugue, pain and fearful of movement, most of the patients are not compliant to the exercises given.

Volunteers have been present in health care settings for centuries. Several studies have shown that volunteers can be an essential part of the healthcare system. They are commonly involved in non-clinical tasks such as providing emotional support to patients and families (Burbeck et al., 2014), assisting with meals (Robinson et al., 2014) and facilitating recreational activities in patients with dementia (Hall et al., 2017).

However, no study has investigated the involvement of volunteers in actual clinical work. Our study aim to explore the feasibility of volunteers involvement in teaching and guiding exercises which conventionally done by physiotherapists, and to investigate the effectiveness of such volunteer service. There is no existing evidence on volunteers dealing with elderly patients in acute stage right after surgery as well, and this clinical research will be the first to explore that.

Arm && Interventions
GroupInterventionDescription
Control armExercise brochureThe control group subjects will receive only standard physiotherapy care and they will be instructed to perform 1 set of exercises daily following a brochure given
Intervention armVolunteers ServiceSubjects in the intervention group will receive standard physiotherapy care and an additional volunteers session once a day for at least 3 times during their stay in the hospital. The volunteer will set up the TKR exercise video for the subjects, then supervise or guide the subjects with the exercises.
Primary Outcome Measures
NameTimeMethod
Quadriceps strengththrough study completion, an average of 5 days

Quads strength will be assessed by using handheld dynamo-meter

Knee flexion and extension range of motionthrough study completion, an average of 5 days

knee range of motion will be measured using goniometer

Secondary Outcome Measures
NameTimeMethod
Pain intensitythrough study completion, an average of 5 days

pain intensity will be assessed by using VAS scale. VAS scale is a valid scale to assess pain intensity. It is a likert scale with 0-10 with 0 is no pain and 10 is maximum pain, Subject will be asked to give a number based on the pain level that they feel.

Length of staythrough study completion, an average of 5 days

Length of hospital stay to discharge home

Timed up and Go testthrough study completion, an average of 5 days

Functional test to measure the duration needed to complete the task

surveythrough study completion, an average of 5 days

survey with likert scale 1-5 to investigate patient acceptance and satisfaction level towards volunteer service

quizthrough study completion, an average of 5 days

quiz with Yes or No to test the knowledge of subjects about post TKR rehab
