Backwards Walking Programme Following Hip and Knee Arthroplasty

Not Applicable

Completed

• Conditions: Hip Arthroplasty; Knee Arthroplasty; Hip Osteoarthritis; Knee Osteoarthritis
• Interventions: Other: Usual Care; Other: Backwards Walking (BW) programme

• Registration Number: NCT04247802
• Lead Sponsor: Oxford University Hospitals NHS Trust

Brief Summary

Backwards walking has been shown to improve balance and walking in patients who have knee Osteoarthritis. It is not known if these benefits may also be seen after surgery in patients who have had a hip or knee replacement because of Osteoarthritis. This study will look to see if it is possible to conduct a bigger study into how effective backwards walking may be after joint replacement. Patients who come to the Nuffield Orthopaedic Centre in Oxford for a hip or knee replacement will be invited. They will be placed into one of two groups at random: a group where they have a course of physiotherapy plus a backwards walking programme or a group where they have a course of physiotherapy. The physiotherapy will last for 12 weeks and those who take part will have two study assessments. The first will be before any treatment and patients will complete five measures and also be issued with a simple tick box diary to complete over the 12 weeks. The second assessment will be after the treatment and will involve the same five measures and the diaries will be collected in. Participants at this assessment will also be asked if they would like to take part in an interview for the study. This is to see what the patients thought of the study. During the study the researcher will record things such as how many patients say 'yes' to the study and how many participants drop out of the treatment, to understand if a bigger study could take place.

Arm && Interventions

Group	Intervention	Description
Usual Care	Usual Care	This group will undertake a routine course of one to one out-patient physiotherapy over 12 weeks. To allow comparison between the two groups the control group will also have up to four review appointments where their home exercise programme can be progressed or regressed. The physiotherapy treatments will be not be restricted (apart from no BW programme) to allow for a pragmatic approach based on the treating clinician's clinical judgement, however their content will be recorded on treatment logs.
Backwards Walking (BW) programme	Backwards Walking (BW) programme	This group will undertake a routine course of one to one out-patient physiotherapy which will include a BW programme. The BW programme will be prescribed by a physiotherapist and the participant will carry it out, along with other prescribed exercises, in their own home. Each participant will initially be prescribed a 5 minute BW programme to be completed once a day. The length of the BW programme and intensity will be progressed or regressed as deemed appropriate by the treating clinician with the aim for patients to achieve at least 10 minutes of BW every day of the week.

Primary Outcome Measures

Name	Time	Method
Berg Balance Scale	12 weeks	The Berg Balance Scale (BBS) is used to objectively determine a patient's ability (or inability) to safely balance during a series of predetermined tasks. It is a 14 item list with each item consisting of a five-point ordinal scale ranging from 0 to 4, with 0 indicating the lowest level of function and 4 the highest level of function. All the item scores are combined to make a total from a minimum of 0 to a maximum of 56. Scores between 41-56 indicate a low risk of falls, 21-40 a medium risk and, below 20 a high risk of falls.

Secondary Outcome Measures

Name	Time	Method
Four Square Step Test	12 weeks	The Four Square Step Test (FSST) is used to assess dynamic stability and co-ordination. It looks at the ability of the subject to step over low objects (walking sticks placed in 'plus' sign position) forward, sideways, and backward in a square pattern clockwise and anticockwise. The subject is timed completing the stepping task as fast as possible without touching the walking sticks.
The Two Minute Walk Test (2MWT)	12 weeks	The Two Minute Walk Test (2MWT) is a measure of self-paced walking ability and functional capacity, particularly for those who cannot manage the longer Six Minute Walk Test (6MWT) or 12 Minute Walk Test. The participant is encouraged to walk as fast as they can, safely, without assistance for two minutes and the distance is measured in metres (m)
30 Second Sit to Stand Test	12 weeks	The 30 Second Sit to Stand Test is a validated clinical measure of lower body strength and dynamic balance. Also known as 30 Second Chair Stand Test (30CST), the 30 Second Sit to Stand Test is designed for testing leg strength and endurance in older adults. The test measures the number of stands a person can complete in 30 seconds. The range of number of stands are from 0 to over 20.
Activities-Specific Balance Confidence Scale	12 weeks	Activities-specific balance confidence (ABC) scale is a structured questionnaire that measures an individual's confidence during ambulatory activities without falling or experiencing a sense of unsteadiness. It consists of 16 questions gauging the individual's confidence while doing specific activities. Scores range for each item from 0 (no confidence) to 100 (completely confident). For the total score all items were added together and divided by 16 to give the average. The following cut-off scores to define level of functioning among active older adults; lower than 50 %: low level of physical functioning; 50-80 %: moderate level of physical functioning; above 80 %: high level of physical functioning.
