    Bennell, KL ; Campbell, PK ; Egerton, T ; Metcalf, B ; Kasza, J ; Forbes, A ; Bills, C ; Gale, J ; Harris, A ; Kolt, GS ; Bunker, SJ ; Hunter, DJ ; Brand, CA ; Hinman, RS (WILEY, 2017-01)
    OBJECTIVE: To investigate whether simultaneous telephone coaching improves the clinical effectiveness of a physiotherapist-prescribed home-based physical activity program for knee osteoarthritis (OA). METHODS: A total of 168 inactive adults ages ≥50 years with knee pain on a numeric rating scale ≥4 (NRS; range 0-10) and knee OA were recruited from the community and randomly assigned to a physiotherapy (PT) and coaching group (n = 84) or PT-only (n = 84) group. All participants received five 30-minute consultations with a physiotherapist over 6 months for education, home exercise, and physical activity advice. PT+coaching participants also received 6-12 telephone coaching sessions by clinicians trained in behavioral-change support for exercise and physical activity. Primary outcomes were pain (NRS) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC; score range 0-68]) at 6 months. Secondary outcomes were these same measures at 12 and 18 months, as well as physical activity, exercise adherence, other pain and function measures, and quality of life. Analyses were intent-to-treat with multiple imputation for missing data. RESULTS: A total of 142 (85%), 136 (81%), and 128 (76%) participants completed 6-, 12-, and 18-month measurements, respectively. The change in NRS pain (mean difference 0.4 unit [95% confidence interval (95% CI) -0.4, 1.3]) and in WOMAC function (1.8 [95% CI -1.9, 5.5]) did not differ between groups at 6 months, with both groups showing clinically relevant improvements. Some secondary outcomes related to physical activity and exercise behavior favored PT+coaching at 6 months but generally not at 12 or 18 months. There were no between-group differences in most other outcomes. CONCLUSION: The addition of simultaneous telephone coaching did not augment the pain and function benefits of a physiotherapist-prescribed home-based physical activity program.

    Bennell, KL ; Ahamed, Y ; Jull, G ; Bryant, C ; Hunt, MA ; Forbes, AB ; Kasza, J ; Akram, M ; Metcalf, B ; Harris, A ; Egerton, T ; Kenardy, JA ; Nicholas, MK ; Keefe, FJ (WILEY, 2016-05)
    OBJECTIVE: To investigate whether a 12-week physical therapist-delivered combined pain coping skills training (PCST) and exercise (PCST/exercise) is more efficacious and cost effective than either treatment alone for knee osteoarthritis (OA). METHODS: This was an assessor-blinded, 3-arm randomized controlled trial in 222 people (73 PCST/exercise, 75 exercise, and 74 PCST) ages ≥50 years with knee OA. All participants received 10 treatments over 12 weeks plus a home program. PCST covered pain education and training in cognitive and behavioral pain coping skills, exercise comprised strengthening exercises, and PCST/exercise integrated both. Primary outcomes were self-reported average knee pain (visual analog scale, range 0-100 mm) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index, range 0-68) at week 12. Secondary outcomes included other pain measures, global change, physical performance, psychological health, physical activity, quality of life, and cost effectiveness. Analyses were by intent-to-treat methodology with multiple imputation for missing data. RESULTS: A total of 201 participants (91%), 181 participants (82%), and 186 participants (84%) completed week 12, 32, and 52 measurements, respectively. At week 12, there were no significant between-group differences for reductions in pain comparing PCST/exercise versus exercise (mean difference 5.8 mm [95% confidence interval (95% CI) -1.4, 13.0]) and PCST/exercise versus PCST (6.7 mm [95% CI -0.6, 14.1]). Significantly greater improvements in function were found for PCST/exercise versus exercise (3.7 units [95% CI 0.4, 7.0]) and PCST/exercise versus PCST (7.9 units [95% CI 4.7, 11.2]). These differences persisted at weeks 32 (both) and 52 (PCST). Benefits favoring PCST/exercise were seen on several secondary outcomes. Cost effectiveness of PCST/exercise was not demonstrated. CONCLUSION: This model of care could improve access to psychological treatment and augment patient outcomes from exercise in knee OA, although it did not appear to be cost effective.

    Comparison of neuromuscular and quadriceps strengthening exercise in the treatment of varus malaligned knees with medial knee osteoarthritis: a randomised controlled trial protocol
    Bennell, KL ; Egerton, T ; Wrigley, TV ; Hodges, PW ; Hunt, M ; Roos, EM ; Kyriakides, M ; Metcalf, B ; Forbes, A ; Ageberg, E ; Hinman, RS (BMC, 2011-12-05)
    BACKGROUND: Osteoarthritis of the knee involving predominantly the medial tibiofemoral compartment is common in older people, giving rise to pain and loss of function. Many people experience progressive worsening of the disease over time, particularly those with varus malalignment and increased medial knee joint load. Therefore, interventions that can reduce excessive medial knee loading may be beneficial in reducing the risk of structural progression. Traditional quadriceps strengthening can improve pain and function in people with knee osteoarthritis but does not appear to reduce medial knee load. A neuromuscular exercise program, emphasising optimal alignment of the trunk and lower limb joints relative to one another, as well as quality of movement performance, while dynamically and functionally strengthening the lower limb muscles, may be able to reduce medial knee load. Such a program may also be superior to traditional quadriceps strengthening with respect to improved pain and physical function because of the functional and dynamic nature. This randomised controlled trial will investigate the effect of a neuromuscular exercise program on medial knee joint loading, pain and function in individuals with medial knee joint osteoarthritis. We hypothesise that the neuromuscular program will reduce medial knee load as well as pain and functional limitations to a greater extent than a traditional quadriceps strengthening program. METHODS/DESIGN: 100 people with medial knee pain, radiographic medial compartment osteoarthritis and varus malalignment will be recruited and randomly allocated to one of two 12-week exercise programs: quadriceps strengthening or neuromuscular exercise. Each program will involve 14 supervised exercise sessions with a physiotherapist plus four unsupervised sessions per week at home. The primary outcomes are medial knee load during walking (the peak external knee adduction moment from 3D gait analysis), pain, and self-reported physical function measured at baseline and immediately following the program. Secondary outcomes include the external knee adduction moment angular impulse, electromyographic muscle activation patterns, knee and hip muscle strength, balance, functional ability, and quality-of-life. DISCUSSION: The findings will help determine whether neuromuscular exercise is superior to traditional quadriceps strengthening regarding effects on knee load, pain and physical function in people with medial knee osteoarthritis and varus malalignment.

    A physiotherapist-delivered integrated exercise and pain coping skills training intervention for individuals with knee osteoarthritis: a randomised controlled trial protocol
    Bennell, KL ; Ahamed, Y ; Bryant, C ; Jull, G ; Hunt, MA ; Kenardy, J ; Forbes, A ; Harris, A ; Nicholas, M ; Metcalf, B ; Egerton, T ; Keefe, FJ (BioMed Central, 2012-07-24)
    BACKGROUND: Knee osteoarthritis (OA) is a prevalent chronic musculoskeletal condition with no cure. Pain is the primary symptom and results from a complex interaction between structural changes, physical impairments and psychological factors. Much evidence supports the use of strengthening exercises to improve pain and physical function in this patient population. There is also a growing body of research examining the effects of psychologist-delivered pain coping skills training (PCST) particularly in other chronic pain conditions. Though typically provided separately, there are symptom, resource and personnel advantages of exercise and PCST being delivered together by a single healthcare professional. Physiotherapists are a logical choice to be trained to deliver a PCST intervention as they already have expertise in administering exercise for knee OA and are cognisant of the need for a biopsychosocial approach to management. No studies to date have examined the effects of an integrated exercise and PCST program delivered solely by physiotherapists in this population. The primary aim of this multisite randomised controlled trial is to investigate whether an integrated 12-week PCST and exercise treatment program delivered by physiotherapists is more efficacious than either program alone in treating pain and physical function in individuals with knee OA. METHODS/DESIGN: This will be an assessor-blinded, 3-arm randomised controlled trial of a 12-week intervention involving 10 physiotherapy visits together with home practice. Participants with symptomatic and radiographic knee OA will be recruited from the community in two cities in Australia and randomized into one of three groups: exercise alone, PCST alone, or integrated PCST and exercise. Randomisation will be stratified by city (Melbourne or Brisbane) and gender. Primary outcomes are overall average pain in the past week measured by a Visual Analogue Scale and physical function measured by the Western Ontario and McMaster Universities Osteoarthritis Index subscale. Secondary outcomes include global rating of change, muscle strength, functional performance, physical activity levels, health related quality of life and psychological factors. Measurements will be taken at baseline and immediately following the intervention (12 weeks) as well as at 32 weeks and 52 weeks to examine maintenance of any intervention effects. Specific assessment of adherence to the treatment program will also be made at weeks 22 and 42. Relative cost-effectiveness will be determined from health service usage and outcome data. DISCUSSION: The findings from this randomised controlled trial will provide evidence for the efficacy of an integrated PCST and exercise program delivered by physiotherapists in the management of painful and functionally limiting knee OA compared to either program alone.

    Efficacy of a multimodal physiotherapy treatment program for hip osteoarthritis: a randomised placebo-controlled trial protocol
    Bennell, KL ; Egerton, T ; Pua, Y-H ; Abbott, JH ; Sims, K ; Metcalf, B ; McManus, F ; Wrigley, TV ; Forbes, A ; Harris, A ; Buchbinder, R (BMC, 2010-10-14)
    BACKGROUND: Hip osteoarthritis (OA) is a common condition leading to pain, disability and reduced quality of life. There is currently limited evidence to support the use of conservative, non-pharmacological treatments for hip OA. Exercise and manual therapy have both shown promise and are typically used together by physiotherapists to manage painful hip OA. The aim of this randomised controlled trial is to compare the efficacy of a physiotherapy treatment program with placebo treatment in reducing pain and improving physical function. METHODS: The trial will be conducted at the University of Melbourne Centre for Health, Exercise and Sports Medicine. 128 participants with hip pain greater or equal to 40/100 on visual analogue scale (VAS) and evidence of OA on x-ray will be recruited. Treatment will be provided by eight community physiotherapists in the Melbourne metropolitan region. The active physiotherapy treatment will comprise a semi-structured program of manual therapy and exercise plus education and advice. The placebo treatment will consist of sham ultrasound and the application of non-therapeutic gel. The participants and the study assessor will be blinded to the treatment allocation. Primary outcomes will be pain measured by VAS and physical function recorded on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) immediately after the 12 week intervention. Participants will also be followed up at 36 weeks post baseline. CONCLUSIONS: The trial design has important strengths of reproducibility and reflecting contemporary physiotherapy practice. The findings from this randomised trial will provide evidence for the efficacy of a physiotherapy program for painful hip OA.

    Neuromuscular Versus Quadriceps Strengthening Exercise in Patients With Medial Knee Osteoarthritis and Varus Malalignment
    Bennell, KL ; Kyriakides, M ; Metcalf, B ; Egerton, T ; Wrigley, TV ; Hodges, PW ; Hunt, MA ; Roos, EM ; Forbes, A ; Ageberg, E ; Hinman, RS (WILEY, 2014-04)
    OBJECTIVE: To compare the effects of neuromuscular exercise (NEXA) and quadriceps strengthening (QS) on the knee adduction moment (an indicator of mediolateral distribution of knee load), pain, and physical function in patients with medial knee joint osteoarthritis (OA) and varus malalignment. METHODS: One hundred patients with medial knee pain, mostly moderate-to-severe radiographic medial knee OA, and varus malalignment were randomly allocated to one of two 12-week exercise programs. Each program involved 14 individually supervised exercise sessions with a physiotherapist plus a home exercise component. Primary outcomes were peak external knee adduction moment (3-dimensional gait analysis), pain (visual analog scale), and self-reported physical function (Western Ontario and McMaster Universities Osteoarthritis Index). RESULTS: Eighty-two patients (38 [76%] of 50 in the NEXA group and 44 [88%] of 50 in the QS group) completed the trial. There was no significant between-group difference in the change in the peak knee adduction moment (mean difference 0.13 Nm/[body weight × height]% [95% confidence interval (95% CI) -0.08, 0.33]), pain (mean difference 2.4 mm [95% CI -6.0, 10.8]), or physical function (mean difference -0.8 units [95% CI -4.0, 2.4]). Neither group showed a change in knee moments following exercise, whereas both groups showed similar significant reductions in pain and improvement in physical function. CONCLUSION: Although comparable improvements in clinical outcomes were observed with both neuromuscular and quadriceps strengthening exercise in patients with moderate varus malalignment and mostly moderate-to-severe medial knee OA, these forms of exercise did not affect the knee adduction moment, a key predictor of structural disease progression.
