Manual therapy for osteoarthritis of the hip or knee - a systematic review

Non-pharmacological and non-surgical interventions to manage patients with knee osteoarthritis: An umbrella review 5-year update

Objective

This umbrella review aimed to summarize (and update) the effectiveness of non-pharmacological and non-surgical interventions for patients with knee osteoarthritis.

Methods

The study followed the PRISMA guidelines. Manual and electronic databases were searched, to identify systematic reviews, following the P (knee osteoarthritis) I (non-pharmacological and non-surgical treatments) C (pharmacological, surgical, placebo, no intervention, or other non-pharmacological/non-surgical conservative treatments) O (pain, function, quality of life, and other knee-specific measures) model. The quality of evidence was assessed using the R-AMSTAR checklist and GRADE principles.

Results

The search yielded 4086 records, of which 61 met the eligibility criteria. After evaluation with R-AMSTAR, four systematic reviews were excluded, resulting in 57 included systematic reviews, with an overall score of 29.6. The systematic reviews were published between 2018 and 2022 (29.8% in 2022), conducted in 19 countries (52.6% in China), and explored 24 distinct interventions. The systematic reviews encompassed 714 trials (mean of 13 ​± ​7.7 studies per systematic review), and 59,343 participants (mean 1041 ​± ​1002 per systematic review, and 82 ​± ​59.2 per study). The majority of participants were older obese women (61.6 ​± ​4.2 years, 30.2 ​± ​3.6 ​kg/m2, 70%, respectively).

Conclusions

Based on the systematic reviews findings, Diet Therapy, Patient Education, and Resistance Training are strongly supported as core interventions for managing patients with knee osteoarthritis. Aquatic Therapy, Balance Training, Balneology, Dietary Supplements, Extracorporeal Shockwave Therapy, and Tai Ji show moderate support. For other interventions, the evidence quality was low, results were mixed or inconclusive, or there was not sufficient efficacy to support their use.

Pragmatism in manual therapy trials for knee osteoarthritis: a systematic review

Introduction

Manual therapy is an often-utilized intervention for the management of knee osteoarthritis (OA). The interpretation of results presented by these trials can be affected by how well the study designs align applicability to real-world clinical settings.

Aim

To examine the existing body of clinical trials investigating manual therapy for knee OA to determine where they fall on the efficacy-effectiveness spectrum.

Methods

This systematic review has been guided and informed by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Randomized controlled trials that investigated manual therapy treatments for adults with knee OA were retrieved via searches of multiple databases to identify trials published prior to April 2023. The Rating of Included Trials on the Efficacy-Effectiveness Spectrum (RITES) tool was used to objectively rate the efficacy-effectiveness nature of each trial design. The Cochrane Risk of Bias 2.0 assessment tool (RoB-2) was used to assess the risk of bias across five domains.

Results

Of the 36 trials, a higher percentage of trials had a greater emphasis on efficacy within all four domains: participant characteristics (75.0%), trial setting (77.8%), flexibility of intervention (58.3%), and clinical relevance of experimental and comparison intervention (47.2%). In addition, 13.9% of the trials had low risk of bias, 41.7% had high risk of bias, and 44.4% had some concerns regarding bias.

Conclusions

While many trials support manual therapy as effective for the management of knee OA, a greater focus on study designs with an emphasis on effectiveness would improve the applicability and generalizability of future trials.

Osteoarthritis of the Knee in Middle-age Athletes: Many Measures are Practiced, but Lack Sound Scientific Evidence

Osteoarthritis of the knee generally affects individuals from the fifth decade, the typical age of middle-age athletes. In the early stages, management is conservative and multidisciplinary. It is advisable to avoid sports with high risk of trauma, but it is important that patients continue to be physically active. Conservative management offers several options; however, it is unclear which ones are really useful. This narrative review briefly reports the conservative options for which there is no evidence of effectiveness, or there is only evidence of short-term effectiveness.

The analgesic effect of joint mobilization and manipulation in tendinopathy: a narrative review

Objective: To summarize the available literature with regards to the potential analgesic effect and mechanism of joint mobilization and manipulation in tendinopathy. Results: The effect of these techniques in rotator cuff tendinopathy and lateral elbow tendinopathy, applied alone, compared to a placebo intervention or along with other interventions has been reported in some randomized controlled trials which have been scrutinized in systematic reviews. Due to the small randomized controlled trials and other methodological limitations of the evidence base, including short-term follow-ups, small sample size and lack of homogenous samples further studies are needed. Literature in other tendinopathies such as medial elbow tendinopathy, de Quervain's disease and Achilles tendinopathy is limited since the analgesic effect of these techniques has been identified in few case series and reports. Therefore, the low methodological quality renders caution in the generalization of findings in clinical practice. Studies on the analgesic mechanism of these techniques highlight the activation of the descending inhibitory pain mechanism and sympathoexcitation although this area needs further investigation. Conclusion: Study suggests that joint mobilization and manipulation may be a potential contributor in the management of tendinopathy as a pre-conditioning process prior to formal exercise loading rehabilitation or other proven effective treatment approaches.

Manual Therapy: Always a Passive Treatment?

The use of manual therapy as an intervention has garnered intense debate, one that is often mired in a straw-man argument that manual therapy is a purely passive intervention. When passive interventions are equated with low-value care, it is easy to deride manual therapy as low-value care. However, manual therapy describes a wide variety of treatments, some with passive components and some that are primarily passive in certain scenarios. But manual therapy can be an integral part of highly active treatment strategies. We implore investigators to describe manual therapy interventions in sufficient detail so that they can be reproduced and thereby help the end users of research (including clinicians) to better assess the value of such interventions. This Viewpoint challenges the assumption that manual therapy is always a passive treatment of low value. J Orthop Sports Phys Ther 2021;51(10):474-477. Epub 1 Jul 2021. doi:10.2519/jospt.2021.10330.

The Efficacy of Manual Therapy in Patients with Knee Osteoarthritis: A Systematic Review

Background and objectives: Osteoarthritis (OA) is among the most common degenerative diseases that induce pain, stiffness and reduced functionality. Various physiotherapy techniques and methods have been used for the treatment of OA, including soft tissue techniques, therapeutic exercises, and manual techniques. The primary aim of this systemic review was to evaluate the short-and long-term efficacy of manual therapy (MT) in patients with knee OA in terms of decreasing pain and improving knee range of motion (ROM) and functionality. Materials and Methods: A computerised search on the PubMed, PEDro and CENTRAL databases was performed to identify controlled randomised clinical trials (RCTs) that focused on MT applications in patients with knee OA. The keywords used were 'knee OA', 'knee arthritis', 'MT', 'mobilisation', 'ROM' and 'WOMAC'. Results: Six RCTs and randomised crossover studies met the inclusion criteria and were included in the final analysis. The available studies indicated that MT can induce a short-term reduction in pain and an increase in knee ROM and functionality in patients with knee OA. Conclusions: MT techniques can contribute positively to the treatment of patients with knee OA by reducing pain and increasing functionality. Further research is needed to strengthen these findings by comparing the efficacy of MT with those of other therapeutic techniques and methods, both in the short and long terms.

Sample size, study length, and inadequate controls were the most common self-acknowledged limitations in manual therapy trials: A methodological review

OBJECTIVES

The aim of this study was to quantify and analyze the presence and type of self-acknowledged limitations (SALs) in a sample of manual therapy (MT) randomized controlled trials.

STUDY DESIGN AND SETTING

We randomly selected 120 MT trials. We extracted data related to SALs from the original reports and classified them into 12 categories. After data extraction, specific limitations within each category were identified. A descriptive analysis was performed using frequencies and percentages for qualitative variables.

RESULTS

The number of SALs per trial article ranged from 0 to 8, and more than two-thirds of trials acknowledged at least two different limitations. Despite its small proportion, 9% of trials did not report SALs. The most common limitation declared, in almost half of our sample, related to sample size (47.5%) followed by limitations related to study length and follow-up (33.3%) and inadequate controls (32.5%).

CONCLUSION

Our results indicate that at least two different limitations are consistently acknowledged in MT trial reports, the most common being those related to sample size, study length, follow-up, and inadequate controls. Analysis of the reasons behind the SALs gives some insights about the main difficulties in conducting research in this field and may help develop strategies to improve future research.

Guidelines for the diagnosis and treatment of osteoarthritis in China (2019 edition)

Osteoarthritis (OA) is a degenerative disease of middle-aged and elderly people, contributed a higher burden of disease in China and the world. In 2017, under the support of the Rheumatology and Immunology Expert Committee of the Cross-Strait Medical and Health Exchange Association. The objective was to develop an evidence-based diagnosis and treatment guideline for OA in China based on emerging new evidence. The guideline was registered at International Practice Guidelines Registry Platform (IPGRP-2018CN028). The grading of recommendations assessment, development and evaluation (GRADE) approach was used to rate the quality of evidence and the strength of recommendations, and the RIGHT (Reporting Items for Practice Guidelines in Healthcare) checklist was followed to report the guideline. The guideline provides recommendations for the OA diagnosis, disease risks monitoring and evaluate, treatment purpose and physical, medical and surgical interventions. This guideline is intended to serve as a tool for Chinese clinicians for the best decisions-making on diagnosis and treatment of OA.

Manual Therapy (Postisometric Relaxation and Joint Mobilization) in Knee Pain and Function Experienced by Patients with Rheumatoid Arthritis: A Randomized Clinical Pilot Study

Objectives

The purpose of this study was to evaluate the impact of manual therapy on the management of rheumatoid arthritis (RA) patients with knee pain.

Materials and Methods

This was a small, randomized clinical pilot study. Subjects were 46 patients with diagnosed RA, randomly assigned to the manual therapy group (postisometric relaxation and joint mobilization) or control group (standard exercise). Subjects in each group had 10 sessions of interventions, once a day with one day break after the sixth day. Outcomes included the pain intensity of knee, Knee Society Score, Oxford Knee Score, and Health Assessment Questionnaire.

Results

There were no statistically significant differences between groups, except for the pain intensity of the knee.

Conclusions

This study suggests that manual therapy (postisometric relaxation and joint mobilization) may have clinical benefits for treating knee pain and function in rheumatoid patients. Further extended studies are expected to determine the effectiveness of manual therapy in RA patients with knee pain.

Short-term Effects of Mulligan's Mobilization With Movement on Pain, Function, and Emotional Aspects in Individuals With Knee Osteoarthritis: A Prospective Case Series

OBJECTIVE

To evaluate the short-term effects of Mulligan's mobilization with movement (MWM) on pain, physical function, emotional aspects, and proprioceptive acuity after a 2-week treatment period and throughout a 3-week follow-up period.

METHODS

A single group of 30 participants (60.96 ± 5.16 years) with symptomatic knee osteoarthritis (KOA) was evaluated. The protocol involved 5 evaluations moments, before (baseline) and after 2 weeks of intervention (24 hours after the last session), and at 3-week follow-up. The intervention included 3 Mulligan's MWM techniques. The variables evaluated were pain (pressure pain threshold and Visual Numeric Scale), physical function (range of motion, proprioceptive acuity, and the Western Ontario and McMaster Universities Osteoarthritis Index) and emotional aspects (Beck Depression Inventory). Analysis of variance for repeated measures was used considering a significance level of 5%.

RESULTS

At the second evaluation (after intervention), the pressure pain threshold presented higher values for rectus femoris, tibialis anterior, and patellar tendon sites and reduced values for the Visual Numeric Scale, Beck Depression Inventory, and Western Ontario and McMaster Universities Osteoarthritis Index compared with baseline. Also, during the follow-up period, all variables returned close to baseline levels. Proprioceptive acuity and range of motion did not present significant changes.

CONCLUSION

Scores for pain relief, physical function, and emotional aspects improved after a course of MWM in this single group of individuals with KOA. Mobilization with movement had limited outcome during follow-up. It suggests that future clinical trials on the use of MWM for KOA should be considered.

Uniaxial Tensile Properties of Atherosclerotic Carotid Artery After Mobilization of Pushing on Qiao-Gong: A Safety Study Using an Animal Model of Carotid Atherosclerosis

OBJECTIVES

This study aimed to preliminarily explore the effects of the soft tissue mobilization of pushing on Qiao-Gong (MPQ) on biomechanical properties of the carotid artery using an animal model of carotid atherosclerosis (CAS).

METHODS

Fifty rabbits were randomly divided into 4 groups: animals with CAS treated with MPQ (CAS-MPQ [n = 15]); animals with CAS treated without MPQ (CAS [n = 15]); normal animals treated with MPQ (normal-MPQ [n = 10]); and a blank control group (n = 10). The MPQ procedure consisted of soft tissue mobilization of the Qiao-Gong acupoint on the front edge of the sternocleidomastoid muscle applied from top to bottom, by flat pushing with the thumb repeatedly for 20 times. Disease in the CAS models was induced by carotid artery balloon injury combined with a high-fat diet for 12 weeks. At the end of modeling, carotid color Doppler ultrasonography examination was performed to confirm which animal models were successfully induced with CAS, excluding model rabbits without typical CAS at the same time. Then, MPQ was applied on rabbits in the CAS-MPQ and the normal-MPQ groups for 3 weeks. By contrast, rabbits in the other 2 groups were fed normally without MPQ. Uniaxial failure tests were later performed on carotid arteries in all 4 groups, and at the end of the study, a 2-way factorial analysis of variance of the results was conducted.

RESULTS

(1) At the end of modeling, 10 rabbits in the CAS-MPQ group and 9 in the CAS group were included with typical carotid atherosclerotic characteristics. (2) Young's elastic modulus of the rabbit carotid artery increased more significantly in the CAS-MPQ group than the CAS group. (3) Compared with normal rabbit carotid arteries, atherosclerotic carotid arteries had lower levels of ultimate stress and ultimate strain but higher levels of ultimate load.

CONCLUSIONS

The uniaxial tensile mechanical properties of the rabbit atherosclerotic carotid artery were impaired after MPQ.

Immediate effects of Mulligan's techniques on pain and functional mobility in individuals with knee osteoarthritis: A randomized control trial

BACKGROUND AND PURPOSE

Mulligan's mobilization with movement was shown to be effective when implemented in multimodal therapy for knee osteoarthritis. However, no study has evaluated the Mulligan's technique in isolation and compared the relative effectiveness with sham-controlled interventions. Hence, the present study examined the immediate effects of Mulligan's techniques with sham mobilization on the numerical pain rating scale (NPRS) and timed up and go (TUG) test in individuals with knee osteoarthritis.

METHODS

Thirty participants (mean age: 55.3 ± 8.3 years) with symptoms at the knee and radiographic diagnosis of knee osteoarthritis were randomized into sham (n = 15) and intervention (n = 15) groups. The intervention (I) group received Mulligan's mobilization glides that resulted in relative pain relief for three sets of 10 repetitions. For the sham (S) group, the therapist's hand was placed over the joint surfaces mimicking the pain-relieving glides, without providing the gliding force. The outcome measures NPRS and TUG were recorded by a blinded assessor pre- and post-intervention.

RESULTS

Statistically significant differences were identified between the groups in post-intervention median (interquartile range) NPRS (I group: 4.00 [2.00-5.00]; S group: 6.00 [4.00-7.00]) and TUG scores (I group: 10.9 [9.43-10.45]; S group: 13.18 [10.38-16.00]) with the intervention group demonstrating better outcomes (p < .05). Within-group, the post-intervention scores of NPRS and TUG were significantly lower (p < .05) compared to the pre-intervention scores in the intervention group. In the sham group, a statistically significant pre-post change was noticed only in the NPRS scores but not in the TUG scores.

CONCLUSION

Mulligan's techniques were effective in improving pain and functional mobility in individuals with knee osteoarthritis. The underlying mechanisms for observed effects must be examined further, as participants reported pain relief following sham mobilization.

Tibiofemoral joint mobilizations following total knee arthroplasty and manipulation under anesthesia

STUDY DESIGN

Case report.

BACKGROUND

The purpose of this case report is to describe the use of tibiofemoral joint mobilizations to improve knee flexion in a patient with arthrofibrosis following total knee arthroplasty (TKA) and failed manipulation under anesthesia (MUA).

CASE DESCRIPTION

A 62-year-old female presented to physical therapy 15 days after TKA with full knee extension, 45 deg of active knee flexion, 48 deg of passive knee flexion, pain, and a Lower Extremity Functional Scale (LEFS) score of 28.

INTERVENTIONS/OUTCOMES

A multimodal intervention strategy was used initially with minimal improvement in knee flexion. The patient was diagnosed with fibrosis and MUA was performed. Passive knee flexion was 80 deg before MUA and 75 deg after MUA. Focused grade III and IV tibiofemoral joint mobilizations were used after MUA. At discharge, the patient had 90 deg of active and 116 deg of passive knee flexion, no pain, and an LEFS score of 80.

DISCUSSION

A conventional multimodal intervention approach was ineffective for a patient who developed arthrofibrosis following TKA. A focused intervention approach of grade III and IV tibiofemoral joint mobilizations improved knee flexion, pain, and function following TKA and failed MUA.

The application of mechanical diagnosis and therapy on hip osteoarthritis: A case report

Background: The prevalence and cost of hip osteoarthritis (OA) is rising. Mechanical diagnosis and therapy (MDT) is an orthopedic classification and treatment system based on mechanical and symptomatic response to repeated and sustained end-range movements. There has been no investigation of the association between MDT and patients diagnosed with hip OA. Case Description: This case report presents a 71-year-old female diagnosed with hip OA and matching the currently accepted clinical prediction rule (CPR) for symptomatic hip OA. The patient was classified and treated by a Diplomat of MDT and co-examiner using MDT. Outcomes: Short- and long-term (13 months) outcomes were excellent, demonstrating rapid abolishment of symptoms and improvement in function in 5 visits over 21 days. The patient demonstrated the ability to prevent and manage reoccurrence of symptoms independently; nevertheless, she received a total hip replacement which was not in accordance with current guidelines and recommendations. Conclusion: This case report raises questions about whether or not pathologies traditionally associated with the etiology of hip OA are actually at fault. Moreover, it raises questions about the utility of special tests and CPRs typically utilized to identify those structures. The case report provides preliminary evidence from one patient that MDT may be capable of providing effective short- and long-term outcomes in the management of hip OA.

Effects of orthopaedic manual therapy in knee osteoarthritis: a systematic review and meta-analysis

OBJECTIVE

This systematic review to aimed to evaluate the effects of orthopaedic manual therapy (OMT) on pain, improving function, and physical performance in patients with knee osteoarthritis (OA).

DATA SOURCES

Four databases (PubMed, Web of Science, CENTRAL, and CINAHL) were searched.

STUDY SELECTION

Trials were required to compare OMT alone or OMT in combination with exercise therapy, with exercise therapy alone or control.

DATA EXTRACTION

Data extraction and risk assessment were done by two independent reviewers. Outcome measures were visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score, WOMAC function score, WOMAC global score, and stairs ascending-descending time.

RESULTS

Eleven randomized controlled trials were included (494 subjects), four of which had a PEDro score of 6 or higher, indicating adequate quality. The results of the meta-analysis indicated that reduction of VAS score in OMT compared with the control group was statistically insignificant (SDM: -0.59; 95% CI: -1.54 to -0.36; P=0.224). The reduction of VAS score in OMT compared with exercise therapy group was statistically significant (SDM: -0.78; 95% CI: -1.42 to -0.17; P=0.013). The reduction of WOMAC pain score in OMT compared with the exercise therapy group was statistically significant (SDM: -0.79; 95% CI: -1.14 to -0.43; P=0.001). Similarly, the reduction of WOMAC function score in OMT compared with the exercise therapy group was statistically significant (SDM: -0.85; 95% CI: -1.20 to -0.50; P=0.001). However, the reduction of WOMAC global score in OMT compared with the exercise therapy group was statistically insignificant (SDM: -0.23; 95% CI: -0.54 to -0.09; P=0.164). The reduction of stairs ascending-descending time in OMT compared with the exercise therapy group was statistically significant (SDM: -0.88; 95% CI: -1.48 to -0.29; P=0.004).

CONCLUSIONS

This review indicated OMT compared with exercise therapy alone provides short-term benefits in reducing pain, improving function, and physical performance in patients with knee OA.

Clinical effectiveness of patella mobilisation therapy versus a waiting list control for knee osteoarthritis: a protocol for a pragmatic randomised clinical trial

INTRODUCTION

Knee osteoarthritis (KOA) is a common, disabling and costly medical condition. The patellofemoral joint is a critical source of pain in individuals with KOA, and coexistence of patellofemoral osteoarthritis (PFOA) and tibiofemoral osteoarthritis (TFOA) is sometimes observed. The identification of subgroups with PFOA and customised interventions to correct underlying pathomechanics is beneficial for individuals with KOA. This study aims to evaluate whether a clinic-based patella mobilisation therapy (PMT) leads to significant improvement in pain, physical function and quality of life of individuals with KOA.

METHODS AND ANALYSIS

A total of 208 participants with coexistence of PFOA and TFOA will be recruited. A pragmatic randomised clinical trial will be conducted, and participants will be randomised into the PMT and waiting list groups. For the PMT group, three manual mobilisation sessions, along with home-based vastus medialis oblique muscle exercise, will be conducted at 2-month intervals. The waiting list group will continue to receive their usual care, and as an incentive the waiting list group will be offered PMT after the study period is over. The primary outcome is the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale, and secondary outcomes include the WOMAC function and stiffness subscales, scores for objective physical function tests (the 30 s chair stand, 40-metre fast-paced walk test, the Timed Up and Go Test), and the EuroQol-5D scores. All outcomes will be evaluated at baseline and 6 months using intention-to-treat and incorporating covariate analysis.

ETHICS AND DISSEMINATION

Ethics approval has been obtained (CREC no: 2014.379). Results of the trial will be submitted for publication in a peer-reviewed journal.

Exercise, Manual Therapy, and Booster Sessions in Knee Osteoarthritis: Cost-Effectiveness Analysis From a Multicenter Randomized Controlled Trial

BACKGROUND

Limited information exists regarding the cost-effectiveness of rehabilitation strategies for individuals with knee osteoarthritis (OA).

OBJECTIVE

The study objective was to compare the cost-effectiveness of 4 different combinations of exercise, manual therapy, and booster sessions for individuals with knee OA.

DESIGN

This economic evaluation involved a cost-effectiveness analysis performed alongside a multicenter randomized controlled trial.

SETTING

The study took place in Pittsburgh, Pennsylvania; Salt Lake City, Utah; and San Antonio, Texas.

PARTICIPANTS

The study participants were 300 individuals taking part in a randomized controlled trial investigating various physical therapy strategies for knee OA.

INTERVENTION

Participants were randomized into 4 treatment groups: exercise only (EX), exercise plus booster sessions (EX+B), exercise plus manual therapy (EX+MT), and exercise plus manual therapy and booster sessions (EX+MT+B).

MEASUREMENTS

For the 2-year base case scenario, a Markov model was constructed using the United States societal perspective and a 3% discount rate for costs and quality-adjusted life years (QALYs). Incremental cost-effectiveness ratios were calculated to compare differences in cost per QALY gained among the 4 treatment strategies.

RESULTS

In the 2-year analysis, booster strategies (EX+MT+B and EX+B) dominated no-booster strategies, with both lower health care costs and greater effectiveness. EX+MT+B had the lowest total health care costs. EX+B cost[Formula: see text]1061 more and gained 0.082 more QALYs than EX+MT+B, for an incremental cost-effectiveness ratio of[Formula: see text]12,900/QALY gained.

LIMITATIONS

The small number of total knee arthroplasty surgeries received by individuals in this study made the assessment of whether any particular strategy was more successful at delaying or preventing surgery in individuals with knee OA difficult.

CONCLUSIONS

Spacing exercise-based physical therapy sessions over 12 months using periodic booster sessions was less costly and more effective over 2 years than strategies not containing booster sessions for individuals with knee OA.

Effect of Land-Based Generic Physical Activity Interventions on Pain, Physical Function, and Physical Performance in Hip and Knee Osteoarthritis: A Systematic Review and Meta-Analysis

OBJECTIVE

The aim of this study was to evaluate the effects of land-based generic physical activity interventions on pain, physical function, and physical performance in individuals with hip/knee osteoarthritis, when compared with a control group that received no intervention, minimal intervention, or usual care.

METHODS

A systematic search for randomized controlled trials on 11 electronic databases (from their inception up until April 30, 2016) identified 27 relevant articles. According to the compendium of physical activities, interventions were categorized into: recreational activities (tai chi/Baduajin-6 articles), walking (9 articles), and conditioning exercise (12 articles).

RESULTS

Meta-analysis for recreational activity (n = 3) demonstrated significant mean difference (MD) of -9.56 (95% confidence interval [CI], -13.95 to -5.17) for physical function (Western Ontario and McMaster Universities Arthritis Index) at 3 mos from randomization. Pooled estimate for walking intervention was not significant for pain intensity and physical performance but was significant for physical function (n = 2) with a MD of -10.38 (95% CI, -12.27 to -8.48) at 6 mos. Meta-analysis for conditioning exercise was significant for physical function (n = 3) with a MD of -3.74 (95% CI, -5.70 to -1.78) and physical performance (6-minute walk test) with a MD of 42.72 m (95% CI, 27.78, 57.66) at 6 mos. The timed stair-climbing test (n = 2) demonstrated a significant effect at 18 mos with a MD of -0.49 secs (95% CI, -0.75 to -0.23).

CONCLUSION

Very limited evidence to support recreational activity and walking intervention was found for knee osteoarthritis, in the short-term on pain and physical function, respectively.

Immediate effects of Maitland mobilization versus Mulligan Mobilization with Movement in Osteoarthritis knee- A Randomized Crossover trial

BACKGROUND

Maitland Mobilization or Mulligan Mobilization with Movement (MWM) approaches have been widely used clinically for pain relief and improving mobility in Osteoarthritis knee. However the experimental evidence supporting the usage of these mobilization techniques as sole interventions in management of Osteoarthritis knee is insufficient.

OBJECTIVE

To determine from Maitland Mobilization and Mulligan MWM, which mobilization technique will be more effective in reducing pain and improving mobility and function in OA knee immediately after the intervention.

STUDY DESIGN

Randomized Crossover trial.

MATERIALS AND METHODS

30 subjects with osteoarthritis knee were recruited and 15 each were randomly allocated to two intervention sequences-one sequence was where Maitland was given first followed by Mulligan and the other was where Mulligan was given first followed by Maitland with a washout period of 48 h in between the two interventions. Numeric Pain Rating Scale (NPRS), Timed Up and Go (TUG) test and Pain free Squat Angle were the outcome measures measured before and immediately after both interventions.

RESULTS

Using Repeated Measures ANOVA for analysis of outcomes between and within interventions, no significant differences were seen between Maitland Mobilization and Mulligan MWM, for NPRS, TUG and Pain free Squat Angle (p = 0.18, p = 0.27,p = 0.17) respectively whereas within the interventions both Maitland and Mulligan all outcome measures showed significant changes (p < 0.001).

CONCLUSION

Thus it can be seen that Maitland mobilization and Mulligan MWM, both are equally effective in osteoarthritis knee in reducing pain and improving functional mobility and pain free squat angle immediately post treatment.

Treatment effectiveness and fidelity of manual therapy to the knee: A systematic review and meta-analysis

Manual therapy (MT) is a commonly used treatment for knee osteoarthritis (OA) but to date only one systematic review has explored its effectiveness. The purpos e of the present study was to perform a systematic review and meta-analysis of the literature, to determine the effectiveness and fidelity of studies using MT techniques in individuals with knee OA. Relevant studies were assessed for inclusion. Effectiveness was measured using effect sizes, and methodological bias and treatment fidelity were both explored. Effect sizes were calculated using standardized mean differences (SMD) based on pooled data depending on statistical and clinical heterogeneity, as well as risk of bias. The search captured 2,969 studies; after screening, 12 were included. Four had a low risk of bias and high treatment fidelity. For self-reported function, comparing MT with no treatment resulted in a large effect size (standardized mean difference [SMD] 0.84), as did adding MT to a comparator treatment (SMD 0.78). A significant difference was found for pain when adding MT to a comparator treatment (SMD 0.73). The findings in the present meta-analytical review support the use of MT versus a number of different comparators for improvement in self-reported knee function. Lesser support is present for pain reduction, and no endorsement of functional performance can be made at this time.

Physiotherapy management of lower limb osteoarthritis

BACKGROUND

Osteoarthritis (OA) of the lower limb affects millions of people worldwide, and results in pain and reduced function. We reviewed guidelines and Cochrane reviews for physical therapy interventions to manage the condition.

SOURCES OF DATA

Evidence from meta-analyses and systematic reviews was included. We also identified the recommendations from guidelines relevant to practice in the UK.

AREAS OF AGREEMENT

There is strongest evidence to support the use of exercise to improve pain, function and quality of life.

AREAS OF CONTROVERSY

There is limited evidence to support the use of some commonly utilized physiotherapy interventions. National Institute for Health and Clinical Excellence do not recommend the use of acupuncture.

GROWING POINTS

Programmes that include single exercise type may be more beneficial than combined strengthening and aerobic interventions.

AREAS TIMELY FOR DEVELOPING RESEARCH

Further research is required to determine how to facilitate long-term engagement with exercise to sustain the beneficial effects on pain, function and quality of life. Studies that investigate packages of care, combining interventions require further investigation.

Chiropractic spinal manipulative therapy for migraine: a three-armed, single-blinded, placebo, randomized controlled trial

Background and purpose

To investigate the efficacy of chiropractic spinal manipulative therapy (CSMT) for migraineurs.

Methods

This was a prospective three‐armed, single‐blinded, placebo, randomized controlled trial (RCT) of 17 months duration including 104 migraineurs with at least one migraine attack per month. The RCT was conducted at Akershus University Hospital, Oslo, Norway. Active treatment consisted of CSMT, whereas placebo was a sham push manoeuvre of the lateral edge of the scapula and/or the gluteal region. The control group continued their usual pharmacological management. The RCT consisted of a 1‐month run‐in, 3 months intervention and outcome measures at the end of the intervention and at 3, 6 and 12 months follow‐up. The primary end‐point was the number of migraine days per month, whereas secondary end‐points were migraine duration, migraine intensity and headache index, and medicine consumption.

Results

Migraine days were significantly reduced within all three groups from baseline to post‐treatment (P < 0.001). The effect continued in the CSMT and placebo group at all follow‐up time points, whereas the control group returned to baseline. The reduction in migraine days was not significantly different between the groups (P > 0.025 for interaction). Migraine duration and headache index were reduced significantly more in the CSMT than the control group towards the end of follow‐up (P = 0.02 and P = 0.04 for interaction, respectively). Adverse events were few, mild and transient. Blinding was strongly sustained throughout the RCT.

Conclusions

It is possible to conduct a manual‐therapy RCT with concealed placebo. The effect of CSMT observed in our study is probably due to a placebo response.

Effects of Expanded Coverage for Chiropractic Services on Medicare Costs in a CMS Demonstration

BACKGROUND

Moderately convincing evidence supports the benefits of chiropractic manipulations for low back pain. Its effectiveness in other applications is less well documented, and its cost-effectiveness is not known. These questions led the Centers for Medicaid and Medicare Services (CMS) to conduct a two-year demonstration of expanded Medicare coverage for chiropractic services in the treatment of beneficiaries with neuromusculoskeletal (NMS) conditions affecting the back, limbs, neck, or head.

METHODS

The demonstration was conducted in 2005-2007 in selected counties of Illinois, Iowa, and Virginia and the entire states of Maine and New Mexico. Medicare claims were compiled for the preceding year and two demonstration years for the demonstration areas and matched comparison areas. The impact of the demonstration was analyzed through multivariate regression analysis with a difference-in-difference framework.

RESULTS

Expanded coverage increased Medicare expenditures by $50 million or 28.5% in users of chiropractic services and by $114 million or 10.4% in all patients treated for NMS conditions in demonstration areas during the two-year period. Results varied widely among demonstration areas ranging from increased costs per user of $485 in Northern Illinois and Chicago counties to decreases in costs per user of $59 in New Mexico and $178 in Scott County, Iowa.

CONCLUSION

The demonstration did not assess possible decreases in costs to other insurers, out-of-pocket payments by patients, the need for and costs of pain medications, or longer term clinical benefits such as avoidance of orthopedic surgical procedures beyond the two-year period of the demonstration. It is possible that other payers or beneficiaries saved money during the demonstration while costs to Medicare were increased.

The effects of manual therapy or exercise therapy or both in people with hip osteoarthritis: a systematic review and meta-analysis

OBJECTIVE

To determine whether manual therapy or exercise therapy or both is beneficial for people with hip osteoarthritis in terms of reduced pain, improved physical function and improved quality of life.

METHODS

Databases such as Medline, AMED, EMBASE, CINAHL, SPORTSDiscus, PubMed, Cochrane Library, Web of Science, Physiotherapy Evidence Database, and SCOPUS were searched from their inception till September 2015. Two authors independently extracted and assessed the risk of bias in included studies. Standardised mean differences for outcome measures (pain, physical function and quality of life) were used to calculate effect sizes. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used for assessing the quality of the body of evidence for each outcome of interest.

RESULTS

Seven trials (886 participants) that met the inclusion criteria were included in the meta-analysis. There was high quality evidence that exercise therapy was beneficial at post-treatment (pain-SMD-0.27,95%CI-0.5to-0.04;physical function-SMD-0.29,95%CI-0.47to-0.11) and follow-up (pain-SMD-0.24,95%CI- 0.41to-0.06; physical function-SMD-0.33,95%CI-0.5to-0.15). There was low quality evidence that manual therapy was beneficial at post-treatment (pain-SMD-0.71,95%CI-1.08to-0.33; physical function-SMD-0.71,95%CI-1.08to-0.33) and follow-up (pain-SMD-0.43,95%CI-0.8to-0.06; physical function-SMD-0.47,95%CI-0.84to-0.1). Low quality evidence indicated that combined treatment was beneficial at post-treatment (pain-SMD-0.43,95%CI-0.78to-0.08; physical function-SMD-0.38,95%CI-0.73to-0.04) but not at follow-up (pain-SMD0.25,95%CI-0.35to0.84; physical function-SMD0.09,95%CI-0.5to0.68). There was no effect of any interventions on quality of life.

CONCLUSION

An Exercise therapy intervention provides short-term as well as long-term benefits in terms of reduction in pain, and improvement in physical function among people with hip osteoarthritis. The observed magnitude of the treatment effect would be considered small to moderate.

Chiropractic spinal manipulative therapy for cervicogenic headache: a study protocol of a single-blinded placebo-controlled randomized clinical trial

Cervicogenic headache (CEH) is a secondary headache which affects 1.0–4.6 % of the population. Although the costs are unknown, the health consequences are substantial for the individual; especially considering that they often suffers chronicity. Pharmacological management has no or only minor effect on CEH. Thus, we aim to assess the efficacy of chiropractic spinal manipulative therapy (CSMT) for CEH in a single-blinded placebo-controlled randomized clinical trial (RCT). According to the power calculations, we aim to recruit 120 participants to the RCT. Participants will be randomized into one of three groups; CSMT, placebo (sham manipulation) and control (usual non-manual management). The RCT consists of three stages: 1 month run-in, 3 months intervention and follow-up analyses at the end of intervention and 3, 6 and 12 months. Primary end-point is headache frequency, while headache duration, headache intensity, headache index (frequency × duration × intensity) and medicine consumption are secondary end-points. Primary analysis will assess a change in headache frequency from baseline to the end of intervention and to follow-up, where the groups CSMT and placebo and CSMT and control will be compared. Due to two group-comparisons, the results with p values below 0.025 will be considered statistically significant. For all secondary end-points and analyses, the significance level of 0.05 will be used. The results will be presented with the corresponding p values and 95 % confidence intervals. To our knowledge, this is the first prospective manual therapy three-armed single-blinded placebo-controlled RCT to be conducted for CEH. Current RCTs suggest efficacy in headache frequency, duration and intensity. However a firm conclusion requires clinical single-blinded placebo-controlled RCTs with few methodological shortcomings. The present study design adheres to the recommendations for pharmacological RCTs as far as possible and follows the recommended clinical trial guidelines by the International Headache Society.

Physical therapies in the management of osteoarthritis: current state of the evidence

PURPOSE OF REVIEW

This review considers the role of physical therapies in osteoarthritis management, highlighting key findings from systematic reviews and randomized controlled trials published in the last 2 years.

RECENT FINDINGS

Three new trials question the role of manual therapy for hip and knee osteoarthritis. No between-group differences in outcome were detected between a multimodal programme including manual therapy and home exercise, and placebo in one trial; a second trial found no benefit of adding manual therapy to an exercise programme, while a third trial reported marginal benefits over usual care that were of doubtful importance. Recent trials have also found no or uncertain clinical benefits of transcutaneous electrical nerve stimulation (TENS) or acupuncture, or of valgus braces or lateral wedge insoles for pain and function in knee osteoarthritis. Available evidence suggests a small to moderate effect of exercise in comparison with not exercising for hip or knee osteoarthritis, although optimum exercise prescription and dosage are unclear. One trial also observed a delay in joint replacement in people with hip osteoarthritis. Two trials have reported conflicting findings about the effects of exercise for hand osteoarthritis.

SUMMARY

Other than exercise, recent data suggest that the role of physical therapies in the treatment of osteoarthritis appears limited.

The Incremental Effects of Manual Therapy or Booster Sessions in Addition to Exercise Therapy for Knee Osteoarthritis: A Randomized Clinical Trial

STUDY DESIGN

A factorial randomized controlled trial.

OBJECTIVES

To investigate the addition of manual therapy to exercise therapy for the reduction of pain and increase of physical function in people with knee osteoarthritis (OA), and whether "booster sessions" compared to consecutive sessions may improve outcomes.

BACKGROUND

The benefits of providing manual therapy in addition to exercise therapy, or of distributing treatment sessions over time using periodic booster sessions, in people with knee OA are not well established.

METHODS

All participants had knee OA and were provided 12 sessions of multimodal exercise therapy supervised by a physical therapist. Participants were randomly allocated to 1 of 4 groups: exercise therapy in consecutive sessions, exercise therapy distributed over a year using booster sessions, exercise therapy plus manual therapy without booster sessions, and exercise therapy plus manual therapy with booster sessions. The primary outcome measure was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC score; 0-240 scale) at 1-year follow-up. Secondary outcome measures were the numeric pain-rating scale and physical performance tests.

RESULTS

Of 75 participants recruited, 66 (88%) were retained at 1-year follow-up. Factorial analysis of covariance of the main effects showed significant benefit from booster sessions (P = .009) and manual therapy (P = .023) over exercise therapy alone. Group analysis showed that exercise therapy with booster sessions (WOMAC score, -46.0 points; 95% confidence interval [CI]: -80.0, -12.0) and exercise therapy plus manual therapy (WOMAC score, -37.5 points; 95% CI: -69.7, -5.5) had superior effects compared with exercise therapy alone. The combined strategy of exercise therapy plus manual therapy with booster sessions was not superior to exercise therapy alone.

CONCLUSION

Distributing 12 sessions of exercise therapy over a year in the form of booster sessions was more effective than providing 12 consecutive exercise therapy sessions. Providing manual therapy in addition to exercise therapy improved treatment effectiveness compared to providing 12 consecutive exercise therapy sessions alone. Trial registered with the Australian New Zealand Clinical Trials Registry (ACTRN12612000460808).

Effects of exercise and manual therapy on pain associated with hip osteoarthritis: a systematic review and meta-analysis

AIM

To explore the effects of exercise (water-based or land-based) and/or manual therapies on pain in adults with clinically and/or radiographically diagnosed hip osteoarthritis (OA).

METHODS

A systematic review and meta-analysis was performed, with patient reported pain assessed using a visual analogue scale (VAS) or the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain subscale. Data were grouped by follow-up time (0-3 months=short term; 4-12 months=medium term and; >12 months=long term), and standardised mean differences (SMD) with 95% CIs were used to establish intervention effect sizes. Study quality was assessed using modified PEDro scores.

RESULTS

19 trials were included. Four studies showed short-term benefits favouring water-based exercise over minimal control using the WOMAC pain subscale (SMD -0.53, 95% CI -0.96 to -0.10). Six studies supported a short-term benefit of land-based exercise compared to minimal control on VAS assessed pain (SMD -0.49, 95% CI -0.70 to -0.29). There were no medium (SMD -0.23, 95% CI -0.48 to 0.03) or long (SMD -0.22, 95% CI -0.51 to 0.06) term benefits of exercise therapy, or benefit of combining exercise therapy with manual therapy (SMD -0.38, 95% CI -0.88 to 0.13) when compared to minimal control.

CONCLUSIONS

Best available evidence indicates that exercise therapy (whether land-based or water-based) is more effective than minimal control in managing pain associated with hip OA in the short term. Larger high-quality RCTs are needed to establish the effectiveness of exercise and manual therapies in the medium and long term.

Chiropractic spinal manipulative therapy for migraine: a study protocol of a single-blinded placebo-controlled randomised clinical trial

INTRODUCTION

Migraine affects 15% of the population, and has substantial health and socioeconomic costs. Pharmacological management is first-line treatment. However, acute and/or prophylactic medicine might not be tolerated due to side effects or contraindications. Thus, we aim to assess the efficacy of chiropractic spinal manipulative therapy (CSMT) for migraineurs in a single-blinded placebo-controlled randomised clinical trial (RCT).

METHOD AND ANALYSIS

According to the power calculations, 90 participants are needed in the RCT. Participants will be randomised into one of three groups: CSMT, placebo (sham manipulation) and control (usual non-manual management). The RCT consists of three stages: 1 month run-in, 3 months intervention and follow-up analyses at the end of the intervention and 3, 6 and 12 months. The primary end point is migraine frequency, while migraine duration, migraine intensity, headache index (frequency x duration x intensity) and medicine consumption are secondary end points. Primary analysis will assess a change in migraine frequency from baseline to the end of the intervention and follow-up, where the groups CSMT and placebo and CSMT and control will be compared. Owing to two group comparisons, p values below 0.025 will be considered statistically significant. For all secondary end points and analyses, a p value below 0.05 will be used. The results will be presented with the corresponding p values and 95% CIs.

ETHICS AND DISSEMINATION

The RCT will follow the clinical trial guidelines from the International Headache Society. The Norwegian Regional Committee for Medical Research Ethics and the Norwegian Social Science Data Services have approved the project. Procedure will be conducted according to the declaration of Helsinki. The results will be published at scientific meetings and in peer-reviewed journals.

Modeled Osteopathic Manipulative Treatments: A Review of Their in Vitro Effects on Fibroblast Tissue Preparations

A key osteopathic tenet involves the body’s ability to self-heal. Osteopathic manipulative treatment (OMT) has been evolved to improve this healing capacity. The authors' in vitro work has focused on modeling 2 common OMT modalities: myofascial release (MFR) and counterstrain. Their studies have evaluated the effects of these modalities on wound healing, cytokine secretion, and muscle repair. The key components of the host response to mechanical forces are fibroblasts, which are the main fascial cells that respond to different types of strain by secreting anti-inflammatory chemicals and growth factors, thus improving wound healing and muscle repair processes. The purpose of this review is to discuss the cellular and molecular mechanisms by which MFR and other OMT modalities work, in particular, the role of strained fibroblasts in inflammation, wound healing, and muscle repair and regeneration. Changing MFR parameters, such as magnitude, duration, direction, and frequency of strain, might uniquely affect the physiologic response of fibroblasts, muscle contraction, and wound healing. If such results are clinically translatable, the mechanisms underlying the clinical outcomes of OMT modalities will be better understood, and these treatments will be more widely accepted as evidence-based, first-line therapies.

Relationship between chiropractic teaching institutions and practice characteristics among Canadian doctors of chiropractic: a random sample survey

OBJECTIVE

The objectives of this study were to determine if faction membership among Canadian doctors of chiropractic (DCs) is associated with differences in educational program characteristics among English-speaking Canadian and United States chiropractic colleges and to determine if those differences are expressed in terms of surveyed attitudes and behaviors regarding treatment efficacy, radiographic imaging, vaccinations, and interprofessional referrals. This study also aims to identify if educational programs may be a potential source of multiple professional identities.

METHODS

A randomly selected sample of Canadian DCs, stratified across the English-speaking provinces, was surveyed by mail. Survey items included school of graduation, self-categorization by chiropractic subgroup, perceptions of condition-specific treatment efficacy, use of plain film radiographic imaging, vaccination attitudes/behaviors, and patient referral patterns. Self-categorization by chiropractic subgroup included: the unorthodox faction (associates the chiropractic subluxation as an encumbrance to the expression of health) and the orthodox perspective (associates with musculoskeletal joint dysfunction, public health, and lifestyle concerns). For data analysis, chiropractic schools were divided into 2 groups according to location: English-speaking Canada and the US. The US was further clustered into liberal ("interested in mixing elements of modern and alternative therapies into the practice of chiropractic") and conservative categories ("chiropractors who believe in continuing the traditions of chiropractic").

RESULTS

Of 740 deliverable questionnaires, 503 were returned for a response rate of 68%. χ(2) Testing revealed significant differences in self-categorized faction membership associated with the clustering of colleges based on ideological viewpoints (χ(2) = 27.06; P = .000). Descriptive results revealed a relationship between school of origin and perceived treatment efficacy, use of radiographic imaging, and vaccination attitudes. No significant differences were found relative to interprofessional referral patterns.

CONCLUSION

Chiropractic program attended is a significant predictor of orthodox vs unorthodox faction membership and professional practice characteristics for Canadian DCs. This suggests that the current chiropractic education system may contribute to multiple professional identities.

Nonpharmacologic therapies in spondyloarthritis

It is accepted that the optimal management of spondyloarthritis requires a combination of non-pharmacological and pharmacological interventions. Non-pharmacologic therapy in spondyloarthritis has generally focused on the exercise regimens whose purpose is to maintain mobility and strength, relieve symptoms, prevent or decrease spinal deformity, contribute to long-term cardiopulmonary health, and improve overall function and quality of life. Exercise programs such as home exercise, group exercise, inpatient programs, and spa exercise have all been the subject of multiple reports that are reviewed here. Studies reviewed support the use of exercise, spa therapy, manual therapy, and electrotherapeutic modalities. Additional topics that are finding relevance in spondyloarthritis are the behavioral interventions that maximize knowledge, motivation for compliance, and healthy lifestyle choices including smoking cessation, weight management, diet, and probiotics. However, the quality and generalizability of the studies are limited.

Manual therapies for primary chronic headaches: a systematic review of randomized controlled trials

This is to our knowledge the first systematic review regarding the efficacy of manual therapy randomized clinical trials (RCT) for primary chronic headaches. A comprehensive English literature search on CINHAL, Cochrane, Medline, Ovid and PubMed identified 6 RCTs all investigating chronic tension-type headache (CTTH). One study applied massage therapy and five studies applied physiotherapy. Four studies were considered to be of good methodological quality by the PEDro scale. All studies were pragmatic or used no treatment as a control group, and only two studies avoided co-intervention, which may lead to possible bias and makes interpretation of the results more difficult. The RCTs suggest that massage and physiotherapy are effective treatment options in the management of CTTH. One of the RCTs showed that physiotherapy reduced headache frequency and intensity statistical significant better than usual care by the general practitioner. The efficacy of physiotherapy at post-treatment and at 6 months follow-up equals the efficacy of tricyclic antidepressants. Effect size of physiotherapy was up to 0.62. Future manual therapy RCTs are requested addressing the efficacy in chronic migraine with and without medication overuse. Future RCTs on headache should adhere to the International Headache Society’s guidelines for clinical trials, i.e. frequency as primary end-point, while duration and intensity should be secondary end-point, avoid co-intervention, includes sufficient sample size and follow-up period for at least 6 months.

Efficacy of passive extension mobilization in addition to exercise in the osteoarthritic knee: an observational parallel-group study

STUDY DESIGN

Pretest post-test observational parallel-group design.

OBJECTIVES

To evaluate the efficacy of passive knee extension mobilization in addition to exercise therapy on extension range of motion (ROM) in patients with osteoarthritis (OA) of the knee. Secondary objectives were to determine changes in pain and functional abilities.

BACKGROUND

Patients with knee OA complain of pain, limited range of motion, and impaired activities. Efficacy of mobilization as a treatment option next to exercises has not been studied rigorously.

METHODS AND MEASURES

Thirty-four participants with persistent knee pain, a positive radiography for knee OA, and a passive extension deficit were included. Seventeen participants (mean age±SD, 59.8±6.1years) were treated with an exercise protocol and were additionally given manual mobilizations to improve passive extension ROM. The other group (mean age±SD, 61.5±7.3years) with equal characteristics was treated with an identical exercise therapy protocol only. Prior to participation, detailed ROM measurements were recorded next to muscle function tests, pain (VAS), six-minute walking tests (6MWTs), a condition-specific questionnaire, and the patient-specific function scale (PSFS). Participants in both groups completed 16 treatment sessions each.

RESULTS

Passive mobilization significantly improved extension ROM in the intervention group (5.2 versus 8.6°, p=.017). The manually mobilized group also had better physical capacities as assessed by 6MWT, less pain, and a lower PSFS score.

CONCLUSION

A combined protocol including exercise therapy and passive mobilization was beneficial for patients with OA of the knee complaining of pain, decreased extension ROM and decreased limited abilities.

Knee extension and stiffness in osteoarthritic and normal knees: a videofluoroscopic analysis of the effect of a single session of manual therapy

STUDY DESIGN

Descriptive biomechanical study using an experimental repeated-measures design.

OBJECTIVE

To quantify the response of participants with and without knee osteoarthritis (OA) to a single session of manual physical therapy. The intervention consisted primarily of joint mobilization techniques, supplemented by exercises, aiming to improve knee extension.

BACKGROUND

While manual therapy benefits patients with knee OA, there is limited research quantifying the effects of a manual therapy treatment session on either motion or stiffness of osteoarthritic and normal knees. Methods The study included 5 participants with knee OA and 5 age-, gender-, and body mass index-matched healthy volunteers. Knee extension motion and stiffness were measured with videofluoroscopy before and after a 30-minute manual therapy treatment session. Analysis of variance and intraclass correlation coefficients were used to analyze the data.

RESULTS

Participants with knee OA had restricted knee extension range of motion at baseline, in contrast to the participants with normal knees, who had full knee extension. After the therapy session, there was a significant increase in knee motion in participants with knee OA (P = .004) but not in those with normal knees (P = .201). For stiffness data, there was no main effect for time (P = .903) or load (P = .274), but there was a main effect of group (P = .012), with the participants with healthy knees having greater stiffness than those with knee OA. Reliability, using intraclass correlation coefficient model 3,3, for knee angle measurements between imaging sessions for all loading conditions was 0.99. Reliability (intraclass correlation coefficient model 3,1) for intraimage measurements was 0.97.

CONCLUSION

End-range knee extension stiffness was greater in the participants with normal knees than those with knee OA. The combination of lesser stiffness and lack of motion in those with knee OA, which may indicate the potential for improvement, may explain why increased knee extension angle was observed following a single session of manual therapy in the participants with knee OA but not in those with normal knees. Videofluoroscopy of the knee appears reliable and relevant for future studies attempting to quantify the underlying mechanisms of manual therapy. J Orthop Sports Phys Ther 2014;44(4):273-282.

Comparação de dois tratamentos fisioterapêuticos na redução da dor e aumento da autonomia funcional de idosos com gonartrose

Objetivo: Comparar o tratamento da terapia manual, associada ao ultrassom, com o tratamento da cinesioterapia convencional, associada ao laser de arseneto de galium (AsGa), na redução da dor e no aumento da autonomia funcional em idosos com gonartrose. Métodos: Estudo clínico, de delineamento quase-experimental. A amostra foi dividida aleatoriamente em dois grupos: grupo experimental 1 (GE1; n=44; idade=68±7,64 anos; índice de massa corporal: 26,77±4,74Kg/m2) - idosos com gonartrose submetidos ao tratamento fisioterapêutico com terapia manual e ultrassom; e grupo experimental 2 (GE2; n=20; idade=70±5,49 anos; índice de massa corporal: 27,11±4,63Kg/m 2 ) - idosos com gonartrose submetidos ao tratamento fisioterápico com cinesioterapia convencional e laserterapia. Foram analisados a autonomia funcional (protocolo do Grupo de Desenvolvimento Latino-Americano para a Maturidade - GDLAM) e o quadro álgico (escala CR10 de Borg). Ambos os GEs participaram de sessões de treinamento com duração de 45 minutos, duas vezes semanais, durante oito semanas consecutivas. O nível de significância foi de p<0,05. Resultados: Observou-se melhora da autonomia funcional pela redução significativa do índice de GDLAM (p<0,001) tanto no GE1 (Δ=16,14) quanto no GE2 (Δ=9,32). Semelhantemente, houve diminuição significativa (p<0,001) do nível de dor tanto no GE1 (Δ=5,09) quanto no GE2 (Δ=7,1). O poder do experimento foi de 98%. Conclusão: Infere-se, assim, que ambos os tratamentos sugeridos neste estudo são eficazes no aumento da autonomia funcional e na redução do quadro álgico de idosos com gonartrose.

Short- and long-term clinical outcomes following a standardized protocol of orthopedic manual physical therapy and exercise in individuals with osteoarthritis of the hip: a case series

OBJECTIVES

Describe short- and long-term outcomes observed in individuals with hip osteoarthritis (OA) treated with a pre-selected, standardized set of best-evidence manual therapy and therapeutic exercise interventions.

METHODS

Fifteen consecutive subjects (9 males, 6 females; mean age: 52±7.5 years) with unilateral hip OA received an identical protocol of manual therapy and therapeutic exercise interventions. Subjects attended 10 treatment sessions over an 8-week period for manual therapy interventions and performed the therapeutic exercise as a home program.

RESULTS

Baseline to 8-week follow-up outcomes were as follows: Harris Hip Scale (HHS) scores improved from 60.3(±10.4) to 80.7(±10.5), Numerical Pain Rating Scale (NPRS) scores improved from 4.3(±1.9) to 2.0(±1.9), hip flexion range of motion (ROM) improved from 99 degrees (±10.6) to 127 degrees (±6.3) and hip internal rotation ROM improved from 19 degrees (±9.1) to 31 degrees (±11.5). Improvements in HHS, NPRS, and hip ROM measures reached statistical significance (P<0.05) at 8-weeks and remained significant at the 29-week follow-up. Mean changes in NPRS and HHS scores exceeded the minimal clinically important difference (MCID) at 8-weeks and for the HHS scores alone at 29 weeks. The 8 and 29 week mean Global Rating of Change scores were 5.1(±1.4) and 2.1(±4.2), respectively. Improved outcomes observed following a pre-selected, standardized treatment protocol were similar to those observed in previous studies involving impairment-based manual therapy and therapeutic exercise for hip OA. Future studies might directly compare the two approaches.
