Randomized Controlled Trial of Dynamic Balance Training in People With Knee Osteoarthritis
2016年6月5日 更新者：University of British Columbia
The Effect of Dynamic Balance Training on Balance and Physical Function in Those With Knee Osteoarthritis
There is a high prevalence of falls in those with knee osteoarthritis (OA) compared to healthy older adults.
Balance is a key element of function that allows individuals to maintain posture and respond to perturbations, and poor balance control, a risk factor for falls, has been noted in those with knee OA.
There is a lack of research guiding treatment for balance deficits in knee OA, with interventions aimed at improving balance deficits in those with knee OA having mixed results.
Targeted dynamic balance interventions in other patient populations have been shown to significantly improve dynamic balance control and physical function.
If results similar to such populations can be achieved, such a program may produce a significant reduction in functional disability in the knee OA population and improve quality of life.
The purpose of this study is to examine the effect of a 10-week targeted dynamic balance intervention on dynamic balance and physical function in people with knee OA.
This will be a randomized controlled trial (RCT).

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
无干预：Wait list
Wait list control group.
Participants will be placed on the wait list and asked to maintain their current routine and level of activity during the 10 week period.
Control group participants will receive the dynamic balance training program in a single training session after the followup (second testing session at 10 weeks).

实验性的：Treatment (balance training)
Targeted dynamic balance training.
Dynamic balance training will consist of progressive exercise training over three phases, with exercises emphasising dynamic balance control, muscle strength and proprioception.
Exercises will be performed four times per week for ten weeks.
Exercises will be taught and supervised by a trained kinesiologist.
Difficulty of exercises will be increased progressively over time by increasing resistance, time of timed exercises, and distance of walking exercises.
Exercises will be progressed to different exercises in each new phase (total 3 phases).
Participants will complete six treatment sessions at the university (during weeks 1, 2, 3, 5, 7, and 9) that will be included in the total number of sessions per week.
All other sessions will be performed at home.
|
Participants in this study group will complete dynamic balance training exercises four times per week, for ten weeks.
Exercise sessions at the university will last approximately one hour, and home exercise sessions will take approximately 30 minutes to complete.
Exercises will emphasize dynamic balance control, muscle strength and proprioception and will be progressed over three phases during the ten weeks (with more difficult exercises phased in, and exercises that have been mastered phased out).

主要结果指标

措施说明 |
大体时间 |
|---|---|---|
|
Change in dynamic balance and mobility from baseline
大体时间：0, 10 weeks
|
The Community Balance and Mobility Scale (CB&M) will be used to assess dynamic balance and mobility.
The CB&M is a scale designed to assess dynamic balance and mobility and is administered by a trained assessor.
The scale consists of 13 items including bending, walking, turning, and stair descent, with a maximum possible score of 96 and minimum score of 0. The scale has been validated and deemed reliable for use in the knee osteoarthritis population.

|
|
Change in self-reported physical function from baseline
大体时间：0, 10 weeks
|
The Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) will be used to assess self-reported physical function.
The WOMAC physical function subscale consists of 17 questions assessing physical function capabilities during activities of daily living.
