RESUMO

BACKGROUND: We aimed to identify important components of, and practical resources relevant for inclusion in, a toolkit to aid exercise delivery for people with hip/knee osteoarthritis. METHOD: An online international multi-disciplinary survey was conducted across 43 countries (139 clinicians, 44 people with hip/knee osteoarthritis and 135 osteoarthritis researchers). Participants were presented with the seeding statement 'Practical resources to aid the implementation of exercise for people with hip/knee osteoarthritis should…' and asked to provide up to 10 open text responses. Responses underwent refinement and qualitative content analysis to create domains and categories. RESULTS: Refinement of 551 open text responses yielded 72 unique statements relevant for analysis. Statements were organised into nine broad domains, suggesting that resources to aid exercise delivery should: (1) be easily accessible; (2) be of high quality; (3) be developed by, and for, stakeholders; (4) include different ways of delivering information; (5) include different types of resources to support exercise and non-exercise components of self-management; (6) include resources on recommended exercises and how to perform/progress them; (7) include tools to support motivation and track progress; (8) include resources to enable tailoring of the programme to the individual and; (9) facilitate access to professional and peer support. CONCLUSION: Our findings identified important components of, and practical resources to include within, a toolkit to aid delivery of exercise for people with hip/knee osteoarthritis. These findings have implications for exercise providers and lay the foundation for the development of a toolkit to help ensure exercise provision aligns with current international recommendations.

RESUMO

PURPOSE: This study assessed the effects of 12-week supervised resistance training combined with home-based physical activity on physical fitness, cancer-related fatigue, depressive symptoms, health-related quality of life (HRQoL), and life satisfaction in female breast cancer survivors. METHODS: A parallel-group, outcome assessor-blinded, randomized controlled trial included 60 female breast cancer survivors who had completed their core treatments within the previous 10 years. Through computer-generated simple randomization, participants were assigned to resistance training (RTG; two sessions/week for 12 weeks plus instructions to undertake ≥ 10,000 steps/d) or control (CG; ≥ 10,000 steps/d only). Outcomes were evaluated at baseline and week 12. Muscular strength was assessed with electromechanical dynamometry. A standardized full-body muscular strength score was the primary outcome. Secondary outcomes included cardiorespiratory fitness, shoulder mobility, cancer-related fatigue, depressive symptoms, HRQoL, and life satisfaction. RESULTS: Thirty-two participants were assigned to RTG (29 achieved ≥ 75% attendance) and 28 to CG (all completed the trial). Intention-to-treat analyses revealed that the standardized full-body muscular strength score increased significantly in the RTG compared to the CG (0.718; 95% CI 0.361-1.074, P < 0.001, Cohen's d = 1.04). This increase was consistent for the standardized scores of upper-body (0.727; 95% CI 0.294-1.160, P = 0.001, d = 0.87) and lower-body (0.709; 95% CI 0.324-1.094, P = 0.001, d = 0.96) strength. There was no effect on cardiorespiratory fitness, shoulder flexion, cancer-related fatigue, depressive symptoms, HRQoL, or life satisfaction. The sensitivity analyses confirmed these results. CONCLUSION: and implication for cancer survivors. In female breast cancer survivors who had completed their core treatments within the past 10 years, adding two weekly sessions of supervised resistance training to a prescription of home-based physical activity for 12 weeks produced a large increase in upper-, lower-, and full-body muscular strength, while other fitness components and patient-reported outcomes did not improve. TRIAL REGISTRATION NUMBER: ISRCTN14601208.

RESUMO

Objective: To assess if a change in physical activity occurred after a one-year weight loss period on either liraglutide or placebo in patients with knee osteoarthritis (OA) and overweight. Method: This is secondary analysis of a one-year weight loss trial, with participants randomised (1:1) to either liraglutide 3 â€‹mg/day or placebo. The main outcome was change in physical activity (min/day) after one year assessed by accelerometer. Physical function was assessed using the Knee Injury and Osteoarthritis Outcome Score (KOOS), function subscale with 100 indicating no disability and 0 indicating extreme disability. Analyses were done on the modified intention to treat population defined as complete baseline accelerometer data. Results: A total of 135 participants were analysed (66 liraglutide; 69 placebo). Daily physical activity time did not change in either group (liraglutide: 15.8 â€‹min/day; placebo: 14.2 â€‹min/day; mean difference 1.6 â€‹min/day (95%CI -16 to 19; P â€‹= â€‹0.90)). The liraglutide group lost -4.1 â€‹kg more than placebo (95% CI -6.0 to -2.1; P â€‹< â€‹0.0001) and improved in KOOS function 3.8 points more than placebo (95% CI 0.9 to 6.7; P â€‹= â€‹0.01). Conclusion: Despite better outcomes on body weight and self-reported physical functioning liraglutide did not induce changes in physical activity over one year in individuals with knee OA.

RESUMO

Knee joint functional deficits are common after anterior cruciate ligament (ACL) injury, but different assessment methods of joint function seem to provide contradicting information complicating recovery monitoring. We previously reported improved perceived knee function and functional performance (forward lunge ground contact time) in patients with an ACL injury from pre to 10 months post ACL reconstruction without improvement in knee-specific biomechanics. To further investigate this discrepancy, we additionally analyzed knee extensor and flexor muscle strength, and movement quality in the forward lunge (subjective and objective evaluations) and performed a full lower limb biomechanical analysis of the forward lunge movement. We included 12 patients with an ACL injury (tested before and after ACL reconstructive surgery) and 15 healthy controls from the previous study to the current investigation. Outcome measures were obtained pre and ~11 months post ACL reconstruction for the patients and at a single time point for the controls. Objective movement quality in the patients with an ACL injury showed an improvement from their pre reconstruction surgery visit to the post reconstruction visit but this was not observable in the subjective evaluation. Knee extensor muscle strength declined after the ACL reconstruction by 29% (p = 0.002) and both knee extensors (p < 0.001) and flexors (p = 0.027) were weaker in the patients post ACL reconstruction compared to healthy controls. ACL injured patients had an altered movement strategy in the forward lunge with reduced knee extensors contribution and increased hip extensor contribution compared to the controls both before and after the reconstruction. The altered movement strategy was associated with knee extensor muscle strength. This explorative study with a limited sample size found that clinicians should be aware that significant functional deficits in the knee extensor muscles, both in isolated muscle strength testing and during a functional movement, may be present although patients perceive an improvement in their knee function and present good functional performance without obvious movement quality issues.

RESUMO

INTRODUCTION: Despite a trend toward the use of perforator-based flaps for autologous breast reconstruction, the m. latissimus dorsi (LD) flap remains a popular alternative. Several studies have sought to uncover the shoulder-related donor-site morbidity, but the results are inconclusive. This study aims at evaluating what impact breast reconstruction with an LD flap has on shoulder strength, range of motion (ROM), lymphedema, sensory disturbances, and patients' ability to perform activities of daily living (ADL). MATERIALS AND METHODS: In a prospective observational study, we examined 20 female patients undergoing delayed breast reconstruction with an LD flap. The primary outcome was a change in shoulder strength, measured with the Biodex System4 Pro-dynamometer. ROM was assessed using two-dimensional photogrammetry. Furthermore, the patients' self-reported pain, lymphedema, sensory disturbances, and ability to perform ADL were assessed using a questionnaire. Measurements were performed pre-operatively at 3 months and 12 months post-operatively. RESULTS: Of the 20 included patients, 17 completed the follow-up. At the 12 months follow-up, a significant loss of isometric shoulder strength of 17% was observed in shoulder adduction (P<0.001) and 21% in extension (P<0.001). Isometric strength and ability to perform ADL and ROM were unchanged. There was a decrease in the number of patients reporting problems with lymphedema (10 to 7) and an increase in the incidence of sensory disturbances (10 to 13). CONCLUSION: A loss of shoulder strength was observed following the transfer of the LD flap; however, the procedure did not hinder the post-operative performance of ADLs for the patients. LD reconstruction seems to be a safe procedure.

RESUMO

OBJECTIVE: To compare the efficacy of an exercise and education programme with open-label placebo given as intra-articular injections of inert saline on pain and function in individuals with knee osteoarthritis (OA). METHODS: In this open-label, randomised controlled trial, we recruited adults aged ≥50 years with symptomatic and radiographically confirmed knee OA in Denmark. Participants were randomised 1:1 to undergo an 8-week exercise and education programme or four intra-articular saline injections over 8 weeks. Primary outcome was change from baseline to week 9 in the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire pain subscale (range 0 (worst)-100 (best)). Prespecified equivalence margins of ±8 KOOS pain points were chosen for the demonstration of comparable efficacy. Key secondary outcomes were the KOOS function and quality of life subscales, and patients' global assessment of disease impact. RESULTS: 206 adults were randomly assigned: 102 to exercise and education and 104 to intra-articular saline injections. For the primary outcome, the least squares mean changes in KOOS pain were 10.0 for exercise and education and 7.3 for saline injections (difference 2.7 points, 95% CI -0.6 to 6.0; test for equivalence p=0.0008). All group differences in the key secondary outcomes respected the predefined equivalence margins. Adverse events and serious adverse events were similar in the two groups. CONCLUSION: In individuals with knee OA, an 8-week exercise and education programme provided efficacy for symptomatic and functional improvements equivalent to that of four open-label intra-articular saline injections over 8 weeks. TRIAL REGISTRATION NUMBER: NCT03843931.

RESUMO

BACKGROUND: Weight loss is critical for preventing and managing obesity-related diseases. There is a notable lack of valid and reliable means to manage patients with overweight/obesity and knee osteoarthritis (KOA). OBJECTIVE: To determine the efficacy and safety of liraglutide in a 30 mg/d dosing in patients with overweight/obesity and KOA. METHODS: The trial was designed as a randomized controlled trial including patients between the age of 18 and 74 y with KOA and a BMI ≥27 (measured in kg/m2).Patients underwent a pre-random assignment diet intervention (week -8 to 0). At week 0, patients having lost >5% of their body weight were randomly assigned to liraglutide 3 mg/d or placebo for 52 wk. The coprimary outcomes were changes in body weight and the Knee injury and Osteoarthritis Outcome Score (KOOS) pain subscale from week 0 to 52. RESULTS: In total, 168 patients enrolled and 156 were randomly assigned to receive liraglutide or placebo. Patients experienced a significant reduction in body weight and KOOS pain during the pre-random assignment dietary intervention period (week -8 to 0). From week 0 to 52 there was a significant difference in body weight between the liraglutide and placebo group (mean changes: -2.8 and +1.2 kg, respectively; group difference, 3.9 kg; 95% CI: -6.9, -1.0; P = 0.008). There was, however, no group difference in KOOS pain (mean changes: 0.4 and -0.6 points, respectively; group difference, 0.9 points; 95% CI: -3.9, 5.7; P = 0.71). Treatment-emergent adverse events related to the gastrointestinal system were experienced by 50.2% and 39.2% of patients in the liraglutide and placebo groups, respectively. CONCLUSIONS: In patients with KOA and overweight/obesity liraglutide added after an 8-wk pre-random assignment diet induced a significant weight loss at >52 wk but did not reduce knee pain compared to placebo. This trial was registered at clinicaltrials.gov as NCT02905864.

RESUMO

OBJECTIVE: This study investigated the effect of exercise therapy on inflammatory activity in synovitis and bone marrow lesions (BMLs) assessed by magnetic resonance imaging (MRI) in patients with knee OA. METHODS: 60 patients with knee OA were randomized 1:1 to 12 weeks of supervised exercise therapy 3 times/week (ET) or a no-attention control group (CG). Synovitis and BMLs were assessed with static MRI with and without contrast and with dynamic contrast enhanced MRI (DCE-MRI). DCE-MRI data was quantified using pixel-by-pixel methodology based on analysis of signal intensity curves. Pain was assessed by the Knee Injury and Osteoarthritis Outcome Score (KOOS). Analyses of covariance were used assessing group differences in changes from baseline to week 12. RESULTS: 33 patients adhered to the protocol and had valid MRI and KOOS data (ET, n = 16, CG, n = 17). Statistically significant and clinically relevant group difference in favour of ET was seen in KOOS pain change (-11.7 points, 95%CI: -20.1 to -3.4). There were statistically significant group differences in DCE-MRI assessed synovitis in the anterior synovium with unchanged inflammatory activity in the ET group compared to the CG. There were no group differences in BMLs and static MRI. CONCLUSION: Inflammatory activity was unchanged, and pain was reduced in patients with knee OA adhering to 12 weeks of exercise therapy compared to a no-attention control group. The reduction in pain was not explained by changes in inflammatory activity. Overall, the results suggest that exercise is not harmful in knee OA. ClinicalTrials.gov number: NCT01545258.

RESUMO

BACKGROUND: Knee osteoarthritis (OA) is a highly prevalent musculoskeletal condition causing pain, physical disability, and reduced quality of life. Exercise and patient education are non-pharmacological interventions for knee OA unanimously recommended as first-line treatments based on extensive research evidence. However, none of the numerous randomised controlled trials of exercise and education for knee OA has used adequate sham/placebo comparison groups because the 'active' ingredients are unknown. Designing and executing an adequate and 'blindable placebo' version of an exercise and education intervention is impossible. Therefore, using an open-label study design, this trial compares the efficacy of a widely used 'state-of-art' exercise and education intervention (Good Life with osteoarthritis in Denmark; GLAD) with presumably inert intra-articular saline injections on improvement in knee pain in patients with knee OA. METHODS: In this open-label randomised trial, we will include 200 patients with radiographically verified OA of the knee and randomly allocate them to one of two interventions: (i) 8 weeks of exercise and education (GLAD) or (ii) Intra-articular injections of 5 ml isotonic saline every second week for a total of 4 injections. Outcomes are taken at baseline, after 8 weeks of treatment (week 9; primary endpoint) and after an additional 4 weeks of follow-up (week 12). The primary outcome is change from baseline in the Knee Injury and Osteoarthritis Outcome Score questionnaire (KOOS) pain subscale score. Secondary outcomes include the Physical function in Activities of Daily Living, Symptoms, and Knee-related Quality of Life subscales of the KOOS, the patients' global assessment of disease impact, physical performance tests, and presence of knee joint swelling. DISCUSSION: This current trial compares a presumably active treatment (GLAD) with a presumably inert treatment (IA saline injections). Both study interventions have well-established and anticipated similar effects on knee OA symptoms, but the underlying mechanisms are unknown. The interpretation of the results of this trial will likely be difficult and controversial but will contribute to a better understanding of the bias introduced in the effect estimation of classically unblindable exercise and education interventions for knee OA.

RESUMO

BACKGROUND: Physical inactivity is a global problem and patients with knee osteoarthritis (OA) are predisposed to inactivity and its health-related consequences. Current guidelines recommend exercise as primary treatment but whether this affects time spent physically inactive is unknown. The objective was to investigate changes in physical inactivity among individuals with knee OA following an educational and exercise program. METHODS: Pragmatic prospective cohort study performed in six physical therapy clinics in Denmark offering a nationwide education and exercise program for knee OA. The program consists of physiotherapy guided education and group-based or home exercise sessions, performed biweekly for approximately eight weeks. The exercises target knee and hip joint stability as well as focus on increasing muscle strength. Primary outcome was time spent physically inactive (min/day), measured with a tri-axial accelerometer mounted on the lateral side of the thigh during the entire exercise program duration. OA symptoms were assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS). RESULTS: Thirty-two individuals with knee OA were analyzed. From baseline to post-intervention, no changes occurred in average time spent physically inactive (mean change: +16.2 min [95% CI -15.7 to 48.1]; P = 0.31), but statistically significant improvements in KOOS pain (+6.7 points [95% CI 2.3 to 11.0]; P = 0.0032) and KOOS function (+5.8 points [95% CI 1.9 to 9.7]; P = 0.0046) were found. CONCLUSIONS: Participating and completing a widely adopted education and exercise program are not associated with spontaneous improvements in physical inactivity despite changes in self-reported pain and function. Interventions specifically targeting physical inactivity are needed. Registration number: www.clinicaltrials.gov: NCT03125954.

RESUMO

OBJECTIVE: To describe spontaneous changes in time spent being physically inactive that is measured continuously by accelerometry during an 8-week weight-loss intervention in overweight/obese individuals with knee osteoarthritis (OA). METHODS: This study was designed as an observational cohort study including individuals from an OA outpatient clinic who were concomitantly overweight/obese and had symptomatic knee OA. Participants completed an 8-week dietary intervention that had been previously shown to induce substantial weight loss. The main outcome was accelerometer-based measurement of daily physical inactivity for 24 hours during the 8-week intervention period that was presented as change in the average daily time spent inactive (sitting, reclined, or sleeping) from 1 week prior to intervention to the last week of the intervention. RESULTS: A total of 124 participants completed the dietary intervention and had valid accelerometer recordings. The mean weight loss was 12.7 kg (95% confidence interval [95% CI] -13.2, -12.1; P < 0.0001) after 8 weeks, which corresponded to a decrease in body mass index of 4.3 kg/m2 (95% CI -4.5, -4.2; P < 0.0001). Significant improvements in OA symptoms (assessed by the Knee Injury and Osteoarthritis Outcome Score [KOOS]) was found across all subscales; an improvement of 12.8 points (95% CI 10.6, 15.0; P < 0.0001) was observed for pain using the KOOS. No statistically significant change occurred in the average daily time spent inactive from baseline to follow-up (mean change 8.8 minutes/day [95% CI -12.1, 29.7]; P = 0.41). CONCLUSION: Physical inactivity remains stable despite a clinically significant weight loss and improvements in knee OA symptoms. Change in inactivity does not seem to occur spontaneously, suggesting that focused efforts to reduce inactive behaviors are needed.

RESUMO

BACKGROUND: Exercise therapy is recommended for knee osteoarthritis (OA), but the underlying mechanisms of pain relief are not fully understood. The purpose of this study was to explore the effects of exercise on muscle perfusion assessed by dynamic contrast enhanced MRI (DCE-MRI) and its association with changes in pain in patients with knee OA. METHODS: Exploratory outcome analyses of a randomised controlled study with per-protocol analyses ( ClinicalTrials.gov : NCT01545258) performed at an outpatient clinic at a public hospital in Denmark. We compared 12 weeks of supervised exercise therapy 3 times per week (ET) with a no attention control group (CG). Analyses of covariance (ANCOVA) were used to assess group mean differences in changes from baseline to week 12 in knee muscle perfusion quantified by DCE-MRI, patient-reported pain and function using the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire, knee extensor and flexor muscle strength tests, and the six-minute walking test (6MWT). Spearman's correlation coefficients were used to determine the correlation between changes in DCE-MRI variables, KOOS, muscle strength, and 6MWT. The potential effect mediation of the DCE-MRI perfusion variables was investigated in a post-hoc mediation analysis. RESULTS: Of 60 participants randomised with knee osteoarthritis, 33 (ET, n = 16, CG, n = 17) adhered to the protocol and had complete DCE-MRI data. At follow-up, there were significant group differences in muscle perfusion changes and clinically relevant group differences in KOOS pain changes (10.7, 95% CI 3.3 to 18.1, P = 0.006) in favor of ET. There were no significant between-group differences on muscle strength and function. The changes in pain and muscle perfusion were significantly correlated (highest Spearman's rho = 0.42, P = 0.014). The mediation analyses were generally not statistically significant. CONCLUSION: The pain-reducing effects of a 12-week exercise program are associated with changes in knee muscle perfusion quantified by DCE-MRI in individuals with knee OA, but whether the effects are mediated by muscle perfusion changes remains unclear.

RESUMO

BACKGROUND: One of the big contributors to physical inactivity in the elderly population is osteoarthritis (OA) of the knee. Digital motivation seems to have a positive effect on individual physical inactivity level, but limited evidence exists on the effects of digital motivation on patients with knee OA. OBJECTIVE: To investigate if motivational text messages reduce time spent physically inactive in patients with knee OA. METHOD: This study was designed as an unblinded pilot randomised controlled trial, randomising participants equally (1:1) to an intervention group (motivational text messages) or control group (no intervention). Participants were recruited from six physical therapy clinics in Denmark. Inclusion criteria were age ≥ 18, diagnosed with knee OA, owner of a smartphone or tablet, and participating or commencing participation in the GLA:D® program. The primary outcome was time spent physically inactive, measured with a tri-axial accelerometer mounted on the lateral side of the thigh. Data on OA symptoms were obtained using the Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire. RESULTS: A total of 49 participants were screened, and 38 participants were included and randomised to either the intervention group (n = 19) or the control group (n = 19). No statistically significant difference between the two groups was found in average change of time spent physically inactive (mean difference 13.2 min/day [95% CI - 41.0 to 67.3]; P = 0.63), time spent standing (mean difference 3.0 min/day [95% CI - 22.7 to 28.7]; P = 0.81), or time spent moving (mean difference - 20.4 min/day [95% CI - 63.0 to 22.3]; P = 0.34) nor was there any difference in change between the two groups on KOOS. CONCLUSION: Motivational text messages have seemed to have no effect on overall time spent physically inactive. TRIAL REGISTRATION: clinicaltrials.gov, NCT03339011. Registered 9 November 2017.

RESUMO

BACKGROUND: People with hand-related rheumatoid arthritis (RA) experience problems performing activities of daily living (ADL). Compensatory strategies to improve ADL ability have shown effective. Similarly, hand exercise has shown effect on pain, grip strength, and self-reported ability. A combination has shown positive effects based on self-report, but self-report and observation provide distinct information about ADL. The purpose of this study was to examine whether hand exercise as add on to compensatory intervention (CIP) will improve observed ADL ability in RA. METHODS: Women (n = 55) with hand-related RA were randomized to CIPEXERCISE (intervention) or CIP only (control). CIP is focused on joint protection, assistive devices, and alternative ways of performing AD. The hand-exercise program addressed range of motion and muscle strength. Primary outcome was change in observed ADL motor ability measured by the Assessment of Motor and Process Skills (AMPS). Baseline measures were repeated after 8 weeks. RESULTS: Improvements in ADL motor ability in CIPEXERCISE (mean change = 0.24 logits; 95% CI = 0.09 to 0.39) and CIPCONTROL (mean change =0.20 logits; 95% CI = 0.05 to 0.35) were statistically significant, with no differences between groups (mean difference = 0.04 logits; 95% CI = - 0.16 to 0.25). Thirteen (46.4%) participants in the CIPEXERCISE and 12 (44.4%) in the CIPCONTROL obtained clinically relevant improvements (≥ 0.30 logits) in ADL motor ability; this group difference was not significant (z = 0.15; p = 0.88). CONCLUSION: Adding hand exercise to a compensatory intervention did not yield additional benefits in women with hand-related RA.

RESUMO

INTRODUCTION: With an increasing prevalence of citizens of older age and with overweight, the health issues related to knee osteoarthritis (OA) will intensify. Weight loss is considered a primary management strategy in patients with concomitant overweight and knee OA. However, there are no widely available and feasible methods to sustain weight loss in patients with overweight and knee OA. The present protocol describes a randomised controlled trial evaluating the efficacy and safety of the glucagon-like peptide-1 receptor agonist liraglutide in a 3 mg/day dosing in patients with overweight and knee OA. METHODS AND ANALYSIS: 150 volunteer adult patients with overweight or obesity and knee OA will participate in a randomised, double-blind, placebo-controlled, parallel-group and single-centre trial. The participants will partake in a run-in diet intervention phase (week -8 to 0) including a low calorie diet and dietetic counselling. At week 0, patients will be randomised to either liraglutide 3 mg/day or liraglutide placebo 3 mg/day for 52 weeks as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle. The co-primary outcomes are changes in body weight and the Knee Injury and Osteoarthritis Outcome Score pain subscale from week 0 to week 52. ETHICS AND DISSEMINATION: The trial has been approved by the regional ethics committee in the Capital Region of Denmark, the Danish Medicines Agency and the Danish Data Protection Agency. An external monitoring committee (The Good Clinical Practice Unit at Copenhagen University Hospitals) will oversee the trial. The results will be presented at international scientific meetings and through publications in peer-reviewed journals.

RESUMO

OBJECTIVE: To investigate differences in gait variability induced by two different single-dose opioid formulations and an inert placebo in healthy volunteers and knee osteoarthritis patients. DESIGN: Experimental, randomized, double-blinded, crossover study of inert placebo (calcium tablets), 50 mg of tapentadol, and 100 mg of tramadol. SETTING: Laboratory setting. SUBJECTS: Healthy volunteers and knee osteoarthritis patients. METHODS: At three visits, separated by seven days, one tablet was administered per visit according to the randomization code. At each visit, a baseline measurement was done before tablet administration, after which hourly measurements were performed for six hours, yielding a total of seven measurements per visit. Gait variability was measured by three-dimensional gait analysis, recorded during six minutes of continuous treadmill walking at self-selected speed. One hundred seventy gait cycles were identified from detection of clear events of the knee joint angle trajectories. Gait variability was assessed as average standard deviations over a gait cycle of the sacrum displacements and accelerations; sagittal plane ankle, knee, and hip joint angles; step widths; and stride times. RESULTS: Twenty-four opioid-naïve and neurologically intact participants (12 healthy volunteers and 12 knee osteoarthritis patients) were included and completed the experiment. Tapentadol reduced the variability of sacrum displacements and accelerations compared with placebo and tramadol. There were no differences between experimental conditions regarding the variability in lower-extremity joint angle variability, step widths, or stride times. CONCLUSIONS: In opioid-naïve and neurologically intact individuals, tapentadol seems to reduce movement variability during treadmill walking, compared with placebo and tramadol. This can be interpreted as a loss of adaptability that might increase the risk of falling if the system is perturbed.

RESUMO

OBJECTIVE: To assess the effect of quadriceps strengthening on quadriceps muscle force, power, and work and tibio-femoral compressive loads during walking in adults with knee osteoarthritis. METHODS: Study design: Two-center, randomized, controlled trial. INTERVENTION: Patients with knee osteoarthritis were randomly allocated to quadriceps strengthening program (3 times weekly) or no attention control group. MAIN OUTCOME MEASURES: Primary outcome was change from baseline in peak quadriceps force during walking at 12 weeks. Secondary outcomes included quadriceps power and work, knee compression forces during walking estimated with musculoskeletal modeling, muscle strength and pain and function. Outcomes were measured at baseline and 12 weeks. RESULTS: 30 patients were randomized to receive either training (n = 15) or no attention (n = 15). At follow-up, there were no statistical differences between groups for maximum quadriceps force, quadriceps positive power, negative work, and positive work, and knee compressive force. Maximum negative quadriceps power in early stance was statistically significantly increased 36% in the training group compared to the control group which was most likely partially a response to faster walking velocity at follow-up. Muscle strength and patient reported pain and function were improved in the training group compared to the control group. CONCLUSIONS: Quadriceps strength training leads to increased muscle strength and improved symptomatic and functional outcomes but does not change quadriceps or knee joint biomechanics during walking. The biomechanical mechanism of improved health with strength training in knee osteoarthritis patients remains unknown. ClinicalTrials.gov Identifier: NCT01538407.

RESUMO

Physical inactivity is important to address, and an objective way of measuring inactivity is by accelerometry. The objective of this study was to determine the reliability and construct validity of the SENS motion system to record physical activity and inactivity in patients with knee osteoarthritis. Participants with an age > 40 years and an average weekly pain above 0 on a numeric rating scale (0 = no pain, 10 = worst pain) were included. Participants had a total of two study visits and at each visit participants completed a standardized activity. Data from 24 participants were analysed. A mean agreement of 99% (SD 3%) for sedentary behaviour and a mean agreement of 97% (SD 9%) for active behaviour were found. The agreement for "walking" was 28% (SD 18%). Mean agreement between recordings on the two visits was 96% (SD 8%) for sedentary behaviour and 99% (SD 1%) for active behaviour. The SENS motion activity measurement system can be regarded as a reliable and valid device for measuring sedentary behaviour in patients with knee OA, whereas detection of walking is not reliable and would require further work.

RESUMO

OBJECTIVES: To analyze if exercise interventions for patients with knee osteoarthritis (OA) following the American College of Sports Medicine (ACSM) definition of muscle strength training differs from other types of exercise, and to analyze associations between changes in muscle strength, pain, and disability. METHODS: A systematic search in 5 electronic databases was performed to identify randomized controlled trials comparing exercise interventions with no intervention in knee OA, and reporting changes in muscle strength and in pain or disability assessed as standardized mean differences (SMD) with 95% confidence intervals (95% CI). Interventions were categorized as ACSM interventions or not-ACSM interventions and compared using stratified random effects meta-analysis models. Associations between knee extensor strength gain and changes in pain/disability were assessed using meta-regression analyses. RESULTS: The 45 eligible trials with 4699 participants and 56 comparisons (22 ACSM interventions) were included in this analysis. A statistically significant difference favoring the ACSM interventions with respect to knee extensor strength was found [SMD difference: 0.448 (95% CI: 0.091-0.805)]. No differences were observed regarding effects on pain and disability. The meta-regressions indicated that increases in knee extensor strength of 30-40% would be necessary for a likely concomitant beneficial effect on pain and disability, respectively. CONCLUSION: Exercise interventions following the ACSM criteria for strength training provide superior outcomes in knee extensor strength but not in pain or disability. An increase of less than 30% in knee extensor strength is not likely to be clinically beneficial in terms of changes in pain and disability (PROSPERO: CRD42014015344).

RESUMO

Study Design Secondary analysis of clinical trial data. Background Knee osteoarthritis (OA) management has changed significantly over recent decades toward nonpharmacological treatments, particularly exercise. However, the optimal exercise program remains to be established. Objective To describe the implementation of standardized rescue exercises for patients with pain exacerbations and to assess whether performing these benefit or further worsen symptoms in patients with exacerbated symptoms of knee OA. Methods The data from 2 randomized controlled studies of exercise in patients with knee OA were used. A supervised, standard exercise program that included standardized "rescue" exercises to be performed in the event of symptomatic exacerbation, defined as knee pain of greater than 5 on a 0-to-10 numeric pain-rating scale, was conducted for 12 weeks at 3 sessions per week. Pain ratings were obtained before and after each exercise session. Results Of 131 participants included, 2 never commenced the exercise program, leaving 129 to be included in the analysis. The analysis was observational and thus had no comparison group. During the program, 36 participants (28%) were referred to the rescue exercises. In 63% of the rescue sessions, the participants experienced decreased pain intensity (average ± SD, -2.6 ± 2.3), 27% reported no change in pain, and 10% reported increased pain intensity (average ± SD, 1.3 ± 0.5). Conclusion Having a predefined and standardized rescue exercise option appears beneficial, and did not result in further worsening of exacerbated knee OA symptoms. The intervention may be particularly relevant for patients with knee OA who have more severe symptoms. Level of Evidence Therapy, level 2b.
