The definition and application of Pilates exercise to treat people with chronic low back pain: a Delphi survey of Australian physical therapists

Evaluating the effects of mobile application-based rehabilitation on improving disability and pain in patients with disputed thoracic outlet syndrome: A randomized controlled trial

BACKGROUND

Disputed thoracic outlet syndrome (D.TOS) stands as one of the primary global contributors to physical disability, presenting diagnostic and treatment challenges for patients and frequently resulting in prolonged periods of pain and functional impairment. Mobile applications emerge as a promising avenue in aiding patient self-management and rehabilitation for D.TOS. This study aimed to investigate the impact of a certain mobile application-based rehabilitation on pain relief and the improvement of disability in patients experiencing D.TOS.

METHODS

Eighty-eight patients diagnosed with D.TOS randomized 1:1 to either the control group (n = 44) or the intervention group (n = 44). Participants in the control group were provided with a brochure containing standard rehabilitation exercise instructions, a written drug prescription from the physician, and guidance on recommended physical activity levels, including home exercises. In contrast, all participants in the intervention group used the mobile application. Disability and pain levels in patients were assessed after six weeks in both groups.

RESULT

Both groups improved pain and disability based on the scaled measurements. According to the questionnaire scale, the intervention group showed a considerable decline in disability; however, there was a significant difference in just one question (P < 0.05). Furthermore, the intervention group showed significant improvement in neck pain NRS (p = 0.024) compared to the control. Based on the shoulder and head pain numeric rate scale (NRSs), both groups showed improvement in disability conditions; but there were no significant differences between the groups (p > 0.05).

CONCLUSION

Mobile applications are promising tools for alleviating disabilities and pain in patients with musculoskeletal conditions. This study confirmed the potential of mobile technology to enhance active and corrective physical activity, thereby reducing pain in patients with D.TOS.

Effects of Pilates Exercises on Core Stability After Recovery from COVID-19: A Randomized Controlled Trial

Purpose

The primary objective was to investigate the effects of Pilates exercises on CS, and the secondary objective was to assess static trunk balance after recovery from COVID-19.

Patients and Methods

145 recovered COVID-19 university students between the ages of 19 and 25 participated in this single-blinded, randomized controlled trial study. The participants were divided into a Pilates group and a control group, each of which received a home exercise program. Core muscle endurance was measured using the five basic endurance tests and static balance using the Prokin system with open eyes (OE) and closed eyes (CE) at baseline and after three months of treatment.

Results

All measured parameters showed improvement within the groups after treatment. Group comparison revealed a significant increase in the Pilates group in all core endurance tests (P<0.001). The Prokin system results showed improvement in the Pilates group after treatment, while perimeter with OE, CE, and ellipse area with EC decreased (P<0.001), but there was no significant difference in ellipse with OE between the groups.

Conclusion

Pilates exercises positively improved core muscle endurance and trunk balance in people infected with COVID-19, which will be reflected in their quality of movement patterns and quality of life.

Neuromuscular electrical stimulation during maximal voluntary contraction: a Delphi survey with expert consensus

PURPOSE

The use of electrical stimulation to assess voluntary activation of muscle/s is a popular method employed in numerous exercise science and health research settings. This Delphi study aimed to collate expert opinion and provide recommendations for best practice when using electrical stimulation during maximal voluntary contractions.

METHODS

A two-round Delphi study was undertaken with 30 experts who completed a 62-item questionnaire (Round 1) comprising of open- and closed-ended questions. Consensus was assumed if ≥ 70% of experts selected the same response; such questions were removed from the subsequent Round 2 questionnaire. Responses were also removed if they failed to meet a 15% threshold. Open-ended questions were analysed and converted into closed-ended questions for Round 2. It was assumed there was no clear consensus if a question failed to achieve a ≥ 70% response in Round 2.

RESULTS

A total of 16 out of 62 (25.8%) items reached consensus. Experts agreed that electrical stimulation provides a valid assessment of voluntary activation in specific circumstances, such as during maximal contraction, and this stimulation can be applied at either the muscle or the nerve. Experts recommended using doublet stimuli, self-adhesive electrodes, a familiarisation session, real-time visual or verbal feedback during the contraction, a minimum current increase of + 20% to ensure supramaximal stimulation, and manually triggering stimuli.

CONCLUSION

The results of this Delphi consensus study can help researchers make informed decisions when considering technical parameters when designing studies involving electrical stimulation for the assessment of voluntary activation.

Transversus Abdominis Ultrasound Thickness during Popular Trunk-Pilates Exercises in Young and Middle-Aged Women

The transversus abdominis (TrA) is a core muscle that contributes to functional mobility and lumbar stability. This study aimed to compare the changes in TrA thickness during different Pilates exercises, and to identify the exercise that elicited the greatest TrA activation. Forty-four healthy women were divided into two groups: young (25-35 years old) and middle-aged (36-55 years old). TrA thickness was assessed by ultrasound while the participants performed five Pilates exercises: basic position, hundred, hip roll, side plank, and dead bug. A repeated measures analysis of variance revealed that the dead bug exercise induced a significantly higher increase in TrA thickness (relative to rest) than the other exercises (p < 0.05). The young group also showed a significantly higher overall TrA thickness than the middle-aged group (p < 0.05). The findings suggest that the dead bug exercise is the most effective for enhancing TrA activation among the Pilates exercises tested. The basic position and the hundred exercises can be used as warm-up exercises before performing more challenging exercises such as the hip roll, the side plank, and the dead bug. The sequence of exercises can be similar for both young and middle-aged women.

The associations of depression, anxiety, and insomnia at baseline with disability at a five-year follow-up point among outpatients with chronic low back pain: a prospective cohort study

BACKGROUND

No previous study has investigated the associations of depression, anxiety, and insomnia at baseline with disability at a five-year follow-up point among outpatients with chronic low back pain (CLBP). The study aimed to simultaneously compare the associations of depression, anxiety, and sleep quality at baseline with disability at a 5-year follow-up point among patients with CLBP.

METHODS

Two-hundred and twenty-five subjects with CLBP were enrolled at baseline, and 111 subjects participated at the five-year follow-up point. At follow-up, the Oswestry Disability Index (ODI) and total months of disability (TMOD) over the past five years were used as the indices of disability. The depression (HADS-D) and anxiety (HADS-A) subscales of the Hospital Anxiety and Depression Scale and the Insomnia Severity Index (ISI) were used to assess depression, anxiety, and insomnia at baseline and follow-up. Multiple linear regression was employed to test the associations.

RESULTS

The scores of the HADS-D, HADS-A, and ISI were correlated with the ODI at the same time points (both at baseline and follow-up). A greater severity on the HADS-D, an older age, and associated leg symptoms at baseline were independently associated with a greater ODI at follow-up. A greater severity on the HADS-A and fewer educational years at baseline were independently associated with a longer TMOD. The associations of the HADS-D and HADS-A at baseline with disability at follow-up were greater than that of the ISI at baseline, based on the regression models.

CONCLUSION

Greater severities of depression and anxiety at baseline were significantly associated with greater disability at the five-year follow-up point. The associations of depression and anxiety at baseline with disability at the long-term follow-up point might be greater than that of insomnia at baseline.

Consensus on Nasal Irrigation in Infants: A Delphi Study

INTRODUCTION

Nasal irrigation is regularly used in infants to relieve upper airway symptoms. However, because there is no consensus on good practice, nasal irrigation in infants is described and applied heterogeneously among clinicians and between clinical trials.

OBJECTIVE

The aim of this study was to establish consensus regarding the use of nasal irrigation in infants.

METHODS

A panel of Belgian physiotherapists and physicians experienced in performing nasal irrigation in infants were surveyed using the Delphi technique. Three survey rounds were used. Participants rated their level of (dis)agreement to each statement in each round using a 6-point Likert scale. Consensus was defined for statements which collected at least 75% of responses in agreement or disagreement. The questionnaire of Round 1 was built on nasal irrigation practice habits previously collected from parents, childcare workers, and healthcare professionals. Questionnaires from rounds 2 and 3 were amended based on experts written feedback.

RESULTS

Thirty experts (12 physicians and 18 physiotherapists) completed all 3 questionnaires. Consensus was achieved for 47 of 75 statements (63%) distributed over the following domains: "contraindications," "indications and frequency of use," "irrigation means," "solution preparation," "solution volume," "realization of the technique," and "assessment of the efficacy of nasal irrigation."

CONCLUSION

This study provides the first well-constructed consensus on good practice on nasal irrigation in infants. Consensus on several statements across different domains were established but require validation in future trials. This study also proposes direction for future research focusing on statements that did not reach consensus.

The Theoretical Framework of the Clinical Pilates Exercise Method in Managing Non-Specific Chronic Low Back Pain: A Narrative Review

Simple Summary

Exercise is important in helping people with chronic low back pain to regain wellness. General exercises such as cycling and strength training helps with the condition but require a longer time to achieve meaningful improvements in pain and function. Movement preference is potentially useful in exercise and can help an individual to achieve improvements faster. The Clinical Pilates exercise method uses movement preference and thus is a hybrid of two of the best exercise techniques in managing chronic low back pain. However, current studies in Clinical Pilates are lacking and thus challenge the translation of the technique into clinical practice. Hence, a narrative review of the theory of the Clinical Pilates exercise method is examined, and current literature is reviewed to provide a guide towards successful exercise prescription. A structured approach to physical assessment of human movement is proposed to guide clinicians or researchers involved in exercise prescription to design effective exercises. The structured assessment approach also helps with managing clinical cases with multiple episodes of injuries. Despite limited evidence, the Clinical Pilates exercise method is safe and provides faster and earlier recovery and the same longer term outcomes as general exercises.

Abstract

Exercise plays an important role in rehabilitating people with chronic low back pain. Aerobic exercise and resistance training are general exercise strategies to manage chronic low back pain, but these strategies require longer intervention period to achieve clinical outcomes in pain reduction and functional improvements. Directional preference is recognised as an important exercise strategy in managing low back pain. The Clinical Pilates exercise method leverages on the directional preference of an individual to achieve clinical outcomes faster. Clinical Pilates is a hybrid of two of the best exercise interventions for low back pain, which are general Pilates and the McKenzie method. Due to the scarcity of Clinical Pilates literature, a review of its theory and studies was undertaken to provide a structured guide to the technique in managing people with chronic low back pain. Hypothetical algorithms are developed to support translation into clinical practice and future research studies. These algorithms are useful in the management of complex cases involving multiple directional trauma. Although limited, current evidence suggests that the Clinical Pilates exercise method is safe and provides faster functional recovery in the early stage of rehabilitation and similar longer term outcomes as general exercises.

A systematic review of the effectiveness of Pilates on pain, disability, physical function, and quality of life in older adults with chronic musculoskeletal conditions

OBJECTIVES

This systematic review aims to evaluate the effectiveness and delivery of Pilates to reduce pain and disability and to improve physical function and quality of life in middle-aged to older adults with a range of chronic musculoskeletal conditions.

METHODS

Searches were conducted using CENTRAL, CINAHL, SCOPUS, Pubmed, PsycInfo, Web of Science Core Collection and Google Scholar. Inclusion criteria were controlled trials and observational studies, population mean age 50 years and over with chronic musculoskeletal conditions, using mat-based Pilates exercise. Outcomes included pain, disability, physical function and quality of life.

RESULTS

Seven studies were included, with a combined total sample of 397 participants (73% female). Pilates was significantly effective (p ≤ 0.05) for reducing back pain, neck pain and pain associated with knee osteoarthritis and osteoporosis. Additional significant disability, physical functioning and quality of life effects were found for back pain, osteoporosis, and knee OA. Overall Pilates was as effective as other exercise. Adherence to group exercise was good, but poor for home exercise. No significant adverse effects were reported.

CONCLUSION

Pilates is a safe and effective exercise intervention for adults over 50 with a diverse range of musculoskeletal conditions which may otherwise put them at risk of becoming sedentary. Although no overall significant superiority was found over other exercise, participants reported psychosocial benefits particular to the Pilates group exercise, with enjoyment a possible positive factor in adherence. Further research on Pilates exercises for various pathologies could inform teaching and improve engagement with older adults, including those with chronic conditions.

A consensus approach toward the standardization of spinal stiffness measurement using a loaded rolling wheel device: results of a Delphi study

BACKGROUND

Spinal stiffness assessment has the potential to become an important clinical measure. Various spinal stiffness-testing devices are available to help researchers objectively evaluate the spine and patient complaints. One of these is VerteTrack, a device capable of measuring posteroanterior displacement values over an entire spinal region. This study aimed to develop a best-practice protocol for evaluating spinal stiffness in human participants using VerteTrack.

METHODS

Twenty-five individuals with research experience in measuring spinal stiffness, or who were trained in spinal stiffness measurement using the VerteTrack device, were invited to participate in this 3-Round Delphi study. Answers to open-ended questions in Round 1 were thematically analyzed and translated into statements about VerteTrack operation for spinal stiffness measurements. Participants then rated their level of agreement with these statements using a 5-point Likert scale in Rounds 2 and 3. A descriptive statistical analysis was performed. Consensus was achieved when at least 70% of the participants either strongly agreed, agreed, (or strongly disagreed, disagreed) to include a statement in the final protocol.

RESULTS

Twenty participants completed Round 1 (80%). All these participants completed Rounds 2 and 3. In total, the pre-defined consensus threshold was reached for 67.2% (123/183) of statements after three rounds of surveys. From this, a best-practice protocol was created.

CONCLUSIONS

Using a Delphi approach, a consensus-based protocol for measuring spinal stiffness using the VerteTrack was developed. This standard protocol will help to improve the accuracy, efficiency, and safety of spinal stiffness measurements, facilitate the training of new operators, increase consistency of these measurements in multicenter studies, and provide the synergy and potential for data comparison between spine studies internationally. Although specific to VerteTrack, the resulting standard protocol could be modified for use with other devices designed to collect spinal stiffness measures.

Consensus on pre-operative total knee replacement education and prehabilitation recommendations: a UK-based modified Delphi study

BACKGROUND

Over 90,000 total knee replacement (TKR) procedures are performed annually in the United Kingdom (UK). Patients awaiting TKR face long delays whilst enduring severe pain and functional limitations. Almost 20% of patients who undergo TKR are not satisfied post-operatively. Optimising pre-operative TKR education and prehabilitation could help improve patient outcomes pre- and post-operatively; however, current pre-operative TKR care varies widely. Definitive evidence on the optimal content and delivery of pre-operative TKR care is lacking. This study aimed to develop evidence- and consensus-based recommendations on pre-operative TKR education and prehabilitation.

METHODS

A UK-based, three-round, online modified Delphi study was conducted with a 60-member expert panel. All panellists had experience of TKR services as patients (n = 30) or professionals (n = 30). Round 1 included initial recommendations developed from a mixed methods rapid review. Panellists rated the importance of each item on a five-point Likert scale. Panellists could also suggest additional items in Round 1. Rounds 2 and 3 included all items from Round 1, new items suggested in Round 1 and charts summarising panellists' importance ratings from the preceding round. Free-text responses were analysed using content analysis. Quantitative data were analysed descriptively. All items rated as 'Important' or 'Very important' by at least 70% of all respondents in Round 3 were included in the final set of recommendations.

RESULTS

Fifty-five panellists (92%) (patients n = 26; professionals n = 29) completed Round 3. Eighty-six recommendation items were included in Round 1. Fifteen new items were added in Round 2. Rounds 2 and 3 therefore included 101 items. Seventy-seven of these reached consensus in Round 3. Six items reached consensus amongst patient or professional panellists only in Round 3. The final set of recommendations comprises 34 education topics, 18 education delivery approaches, 10 exercise types, 13 exercise delivery approaches and two other treatments.

CONCLUSIONS

This modified Delphi study developed a comprehensive set of recommendations that represent a useful resource for guiding decision-making on the content and delivery of pre-operative TKR education and prehabilitation. The recommendations will need to be interpreted and reviewed periodically in light of emerging evidence.

Perceived Barriers, Enablers, and Modifications to Tests Assessing Pediatric Lower Limb Neurological Impairment: An International Delphi Survey

OBJECTIVES

Accurate, clinically meaningful outcome measures that are responsive to change are essential for selecting interventions and assessing their effects. Little guidance exists on the selection and administration of neurological impairment tests in children with a neurological condition. Clinicians therefore frequently modify adult assessments for use in children, yet the literature is inconsistent. This study aims to establish consensus on neurological conditions most likely to require neurological impairment test in pediatrics and the barriers, enablers, and modifications perceived to enhance test reliability.

METHODS

Over a 2-round modified Delphi study, a panel of experts (n = 24) identified neurological conditions perceived to typically require pediatric neurological testing and the modifications to address barriers/enablers to testing. Experts comprised physical therapists with evidence of advanced training or research in pediatrics. Using a 6-point Likert scale (6 = strongly agree, 5 = agree, 4 = somewhat agree, 3 = somewhat disagree, 2 = disagree, 1 = strongly disagree), experts rated statements from existing literature. Thematic analyses were conducted on responses to open-ended questions. A priori consensus was pre-set at 65% agreement/disagreement. Median, mode, and interquartile ranges estimated perceived importance. Cessation was pre-determined by non-consensus items <10% and panel fatigue.

RESULTS

Experts reached consensus on 107/112 (96%) items, including identifying 25/26 (96%) neurological conditions they perceived to require routine neurological testing. Experts strongly agreed with high importance that appropriately trained, experienced therapists are less variable when testing children. Communication modifications were perceived as most important.

CONCLUSION

High levels of consensus support the use of lower limb neurological testing in a range of pediatric neurological conditions. Trained clinicians should document modifications such as visual aid use. Using recommended modifications could encourage consistency among clinicians.

IMPACT

This is the first study to our knowledge to identify the barriers and enablers to pediatric neurological testing. Barriers and enablers were partially addressed through suggested modifications. Further rigorous examination of these modifications is required to support their use.

LAY SUMMARY

This study supports that clinicians should adapt their communication for children and young people with neurological problems to include visual aids and equipment demonstration.

A qualitative systematic review of the views, experiences and perceptions of Pilates-trained physiotherapists and their patients

OBJECTIVES

A review of qualitative studies exploring Pilates-trained physiotherapists and their patients' perspectives and experiences of Pilates, aiming to improve practice and provide a deeper insight into the way this method is being utilized along with its effects on participants.

DESIGN

Qualitative evidence synthesis using meta-ethnography.

DATA SOURCES

A comprehensive search strategy, limited to English language articles, was conducted to MEDLINE (PubMed), EMBASE, CINAHL, PEDro and Cochrane Central for the period of January 2000 (inception) to June 2020. This was supplemented by identification of Grey literature through Google Scholar, website searching and reference lists.

STUDY SELECTION

Qualitative studies reporting experiences and perceptions of patients' or Pilates-trained physiotherapists' regarding the efficacy of Pilates for the management of chronic musculoskeletal conditions. After a process of exclusion, eight studies were included in the synthesis.

DATA EXTRACTION

The textual data were analysed by a qualitative software program. Studies were critically appraised independently by two reviewers.

DATA SYNTHESIS

Articles were synthesized using a technique of meta-ethnography. Three themes emerged from the process of reciprocal translation: (1) Benefits of the Pilates approach; (2) most effective ways to utilize and most beneficial parameters and (3) risks, precautions, contraindications and indications.

CONCLUSION

This is the first qualitative evidence synthesis of practitioners' and patients' perspectives of Pilates. Findings support evidence for the various benefits of this approach and provide fresh insight into the way this method can be practiced to maximize efficiency and focus on the patients' needs.

KEY RECOMMENDATIONS

Pilates-trained physiotherapists identified that Pilates can be tailored to individual requirements, preferences and needs, to promote self-management to facilitate clinical and cost-effective care.

Are stabilisation exercises different to other treatments in improving physical activity or reducing disability for people with persistent low back pain? A systematic literature review

Background/Aims

Stabilisation exercises are commonly prescribed for people with persistent low back pain. However, for some patients, it has been hypothesised that stabilisation exercises could draw attention to protecting the core, promote hypervigilance and inhibit volitional movement. The aim of this study was to compare the effectiveness and reported adverse events, in particular fear avoidance, of stabilisation exercises compared with placebo or other treatments offered by physiotherapists on the outcome of disability and activity at 12- and 24-months' follow-up.

Methods

The following electronic databases were searched: Embase, Medline, AMED, CINAHL, from inception to June 2019. Only randomised controlled trails were included. Study selection, data extraction and appraisal of quality criteria using PEDro, were undertaken by two independent assessors.

Results

Seven studies (n=1820) were eligible. Of six studies that reported adverse effects in the group receiving stabilisation exercises, four reported none and two reported mild exacerbation of pain locally or elsewhere. Fear avoidance was not investigated in any of the studies. Across the studies, 12 analyses were reported and included seven different comparator groups and three outcome measures: Oswestry Disability Index (n=1), Roland Morris Disability Questionnaire (n=5), Patient Specific Functional Scale (n=4). Two studies included a 24-month follow up in addition to a 12-month follow up. Of the 12 studies, nine reported no significant differences between the effectiveness of stabilisation exercises and comparator groups. Stabilisation exercises were more effective than comparator groups for the following three analyses: compared to manual therapy or education at 12 but not 24 months for the Oswestry Disability Index (15.71, 95% confidence interval 19.3–10.01); compared to placebo for the Patient Specific Functional Scale (1.5, 95% confidence interval 0.7–2.2) but not the Roland Morris Disability Questionnaire; and compared to high load lifting for the Patient Specific Functional Scale (1.8 95% confidence interval 2.8–0.7).

Conclusions

Stabilisation exercises are safe and equally effective to other treatments, and possibly superior for some outcomes at some time points. No or only mild adverse effects were reported. However, none of the studies measured fear avoidance as an outcome and we recommend this be included in future randomised controlled trials measuring the effectiveness of stabilisation exercises.

A Delphi study to establish consensus on a definition of major bleeding in adult trauma

BACKGROUND

The majority of potentially preventable deaths in trauma are due to uncontrolled hemorrhage and occur early after injury. How major bleeding is defined is integral to early identification and treatment of this group of high-risk patients. However, there is no consensus on a definition of major bleeding in trauma. The aim of this Delphi study was to develop a consensus definition for research, with transfusion used as a surrogate marker of bleeding.

STUDY DESIGN AND METHODS

Trauma experts from three international groups were invited to take part in an online Delphi survey. Over the course of four rounds, the group developed a number of definitions of major bleeding and reached consensus on a new definition.

RESULTS

Forty-four trauma experts agreed to become members of the Delphi panel, and 30 of 44 (68%) completed all four rounds. The panel agreed to exclude the historical massive transfusion definition (≥10 units of red blood cells within 24 hours). Consensus was reached on a new definition for use in clinical research: 4 or more units of any blood component within 2 hours of injury.

CONCLUSION

This Delphi process has yielded a pragmatic transfusion-based definition of major bleeding. The consensus definition differs from historical definitions: a shorter time frame to reflect the acuity of bleeding, and multiple blood components in keeping with a balanced approach to resuscitation. The definition developed may be best suited to mature trauma systems (reflecting the demographics of the expert panel), and could be used to guide registry data recording and to characterize patients at risk of major bleeding.

"How do Pilates Trained Physiotherapists utilize and value Pilates Exercise for MSK conditions? A Qualitative Study"

BACKGROUND

Pilates is a popular exercise therapy approach offering numerous benefits, including muscular strength, flexibility, control, and core stability. Pilates has been widely utilized in the prevention and rehabilitation of a variety of musculoskeletal disorders.

OBJECTIVES

The aim of this study was to explore the experiences and opinions of Pilates trained NHS and private practice physiotherapists in the UK, regarding the perceived benefits, risks, delivery and rationale for this exercise method.

METHODS

This qualitative study used a self-designed electronic survey to retrieve the views of 30 physiotherapists, who had undertaken formal Pilates Instruction training, recruited by a purposive and snowball sampling method. Questions were either multiple choice or open-ended, examined via thematic analysis.

RESULTS

Physiotherapists identified the most important benefits of Pilates as reduction in fear-avoidance, improving bodily awareness and increasing muscular strength. Exercises that promote general movement were highlighted as being particularly useful, with a majority recommending daily practice for optimum benefit. Participants recognized lack of core strength as a key indicator, whereas others criticized excessive focus on this principle.

CONCLUSIONS

Physiotherapists identified a range of inter-linked benefits and recognized that Pilates is hugely modifiable. Individualizing exercises can further encourage participation and negate the restriction of some health conditions. NHS and Private Practice Therapists utilize Pilates in a similar way, although rationales for its use may differ, as the justification for Pilates exercise may be evolving. Pilates appears a valuable methodology in the NHS, which can help patients engage with activity.

Examination of a Subgroup of Patients With Chronic Low Back Pain Likely to Benefit More From Pilates-Based Exercises Compared to an Educational Booklet

OBJECTIVE

To investigate whether 2 previously published classification approaches, the updated treatment-based classification system and a Pilates subgroup defined by a preliminary clinical prediction rule, could identify patients with chronic low back pain who would benefit more from Pilates exercises compared to an educational booklet.

DESIGN

Secondary analysis of a randomized controlled trial.

METHODS

Two hundred twenty-two patients received advice and were randomly allocated to a group that received an educational booklet with no additional treatment (n = 74) or a group that received Pilates-based exercise treatment (n = 148) 2 or 3 times a week. At baseline, using a treatment-based classification system, patients were classified as having a good prognosis (positive movement control) or a poor prognosis. Similarly, using the Pilates clinical prediction rule, patients were classified as having a good prognosis (positive) or a poor prognosis (negative). The analysis was conducted using linear regression models to analyze the interaction between subgroup characteristics and treatment effect size, with changes in pain and disability from baseline to 6 weeks after randomization as dependent variables.

RESULTS

None of the interaction terms for pain and disability were statistically significant. The treatment effect of Pilates versus an educational booklet was similar in all subgroups.

CONCLUSION

The treatment-based classification system and the Pilates clinical prediction rule did not differentiate subgroups of patients with chronic low back pain who were more or less likely to benefit more from Pilates compared to an educational booklet.

Neuromuscular exercise reduces low back pain intensity and improves physical functioning in nursing duties among female healthcare workers; secondary analysis of a randomised controlled trial

Background

Low back pain (LBP) is common among healthcare workers, whose work is physically strenuous and thus demands certain levels of physical fitness and spinal control. Exercise is the most frequently recommended treatment for LBP. However, exercise interventions targeted at sub-acute or recurrent patients are scarce compared to those targeted at chronic LBP patients. Our objective was to examine the effects of 6 months of neuromuscular exercise on pain, lumbar movement control, fitness, and work-related factors at 6- and 12-months’ follow-up among female healthcare personnel with sub-acute or recurrent low back pain (LBP) and physically demanding work.

Methods

A total of 219 healthcare workers aged 30–55 years with non-specific LBP were originally allocated to four groups (exercise, counselling, combined exercise and counselling, control). The present study is a secondary analysis comparing exercisers (n = 110) vs non-exercisers (n = 109). Exercise was performed twice a week (60 min) in three progressive stages focusing on controlling the neutral spine posture. The primary outcome was intensity of LBP. Secondary outcomes included pain interfering with work, lumbar movement control, fitness components, and work-related measurements. Between-group differences were analysed with a generalised linear mixed model according to the intention-to-treat principle. Per-protocol analysis compared the more exercised to the less exercised and non-exercisers.

Results

The mean exercise attendance was 26.3 (SD 12.2) of targeted 48 sessions over 24 weeks, 53% exercising 1–2 times a week, with 80% (n = 176) and 72% (n = 157) participating in 6- and in 12-month follow-up measurements, respectively. The exercise intervention reduced pain (p = 0.047), and pain interfering with work (p = 0.046); improved lumbar movement control (p = 0.042), abdominal strength (p = 0.033) and physical functioning in heavy nursing duties (p = 0.007); but had no effect on other fitness and work-related measurements when compared to not exercising. High exercise compliance resulted in less pain and better lumbar movement control and walking test results.

Conclusion

Neuromuscular exercise was effective in reducing pain and improving lumbar movement control, abdominal strength, and physical functioning in nursing duties compared to not exercising.

Perceived benefits, rationale and preferences of exercises utilized within Pilates group exercise programmes for people with chronic musculoskeletal conditions: A questionnaire of Pilates-trained physiotherapists

INTRODUCTION

An estimated 29% of the population, around 17.8 million people, live with a musculoskeletal condition in the UK. Pilates exercise has positive benefits, including reducing pain and disability for people with musculoskeletal conditions. The aim of the present study was to explore the views of Pilates-trained physiotherapists in relation to the perceived benefits of, and clinical reasoning for, exercise prescription in Pilates classes.

METHODS

A qualitative approach was taken to both data collection and analysis, using a thematic framework. Data were collected via electronic questionnaires using open-ended questions. Participants included 15 Pilates-trained physiotherapists who regularly ran Pilates exercise classes within seven private physiotherapy clinics for people with a range of chronic musculoskeletal conditions.

RESULTS

The results were organized into six main themes: Perceived benefits 1: Improved function and increased levels of activity. Perceived benefits 2: Improved ability to manage their musculoskeletal condition autonomously; Efficacy of group Pilates exercise; Optimum combination of exercises used within a class; Physiotherapist rationale for the most effective exercises; Precautions with specific exercises.

CONCLUSIONS

The study was the first to investigate perceived benefits, rationale and preference for choice of exercise among Pilates-trained physiotherapists. Physiotherapists felt that the Pilates classes facilitated an active lifestyle and self-management approach. They used a combination of exercises in each class to address all the main muscle groups, but some had specific exercise preferences related to the patients' needs. Exercises were linked to evidence around neuromuscular control, direction preference and biomechanical principles.

Effectiveness of the Pilates method versus aerobic exercises in the treatment of older adults with chronic low back pain: a randomized controlled trial protocol

BACKGROUND

Chronic low back pain is potentially disabling for older adults, and exercise is considered the best treatment. The Pilates method and aerobic exercises have been proven to be effective in pain and function improvement in patients with low back pain, but evidence in the treatment of older adults with low back pain is scarce. Therefore, the objective of this study is to investigate the effectiveness of the Pilates method compared to aerobic exercises in the treatment of older adults with chronic nonspecific low back pain.

METHODS

This is a randomized controlled trial with blinded assessor, to be held in a physical therapy clinic in Sao Paulo, Brazil. Seventy four patients aged 65 to 85 years with chronic nonspecific pain will be randomized into Pilates Group (n = 37) with exercises based on the Pilates method and Aerobic Group (n = 37) with treadmill aerobic exercise. The primary outcomes will be pain intensity and general disability, assessed eight weeks after randomization. The secondary outcomes will be: pain intensity and general disability, assessed six months after randomization; and global perceived improvement, specific disability, dynamic balance, muscle strength (gluteus maximus, gluteus medius, and lateral hip rotators), and pressure pain threshold, assessed eight weeks and six months after randomization. Therapists and patients will not be blinded.

DISCUSSION

This study has the potential to reduce pain and, consequently, improve balance and function of older adults with chronic low back pain with both therapies. However, Pilates may be more effective because the exercises are more targeted to the trunk stabilization muscles. The results of this study may provide valuable information on the effects of Pilates and aerobic exercise in older adults with chronic low back pain and contribute to a better selection of the treatment program according to the patient preference.

Using stochastic resonance and strength training as part of a rehabilitation programme for recurrent low back pain treatment: a case study

Low back pain (LBP) is a common disabling health problem that can cause decreased spine proprioception. Stochastic resonance (SR) can influence detection performance, besides improving patients with significant sensory deficits, but have not been thoroughly tested for LBP. This study aimed to examine the application of SR therapy (SRT) and strength training for LBP treatment. The subject was a resistance-trained male in his early thirties. His back pain was unbearable after a strength training session. Standard pain relief alleviated the pain but the LBP developed at a similar intensity after 4 weeks. SRT (4–5 sets ×90 sec, 30-sec rest interval, supine position) was prescribed along with other exercises for 3 weeks (phase 1), and followed by tailor-made strength training for 16 weeks (phase 2). The Oswestry Disability Index was 66.7% (interpreted as “crippled”) prior to first SRT, and reduced to minimal levels of 15.6% and 6.7% after four and seven SRT sessions, respectively. Similarly, pain intensity was ranging from 5 to 9 (distracting-severe) of the Numeric Rating Scale (NRS-11) prior to the first session but this was reduced considerably after four sessions (NRS-11: 0–1). During phase 2, the patient performed without complaining of LBP, two repetitions of bench press exercise at a load intensity of 1.2 his body weight and attained 4 min of plank stabilisation. This LBP management strategy has a clinically meaningful effect on pain intensity, disability, and functional mobility, by receding the recurrent distracting to severe LBP.

Aquatic Exercises in the Treatment of Low Back Pain: A Systematic Review of the Literature and Meta-Analysis of Eight Studies

OBJECTIVE

Low back pain is the most common musculoskeletal condition with a high prevalence. There was no sufficient evidence to recommend that aquatic exercise was potentially beneficial to patients with low back pain. The aim of this study was to systematically analyze all evidence available in the literature about effectiveness of the aquatic exercise.

DESIGN

A comprehensive search of PubMed, the Cochrane Library, Embase, and Cumulative Index to Nursing and Allied Health was conducted from their inceptions to November 2016 for randomized controlled trials, which concerned the therapeutic aquatic exercise for low back pain. The results were expressed in terms of standardized mean difference and the corresponding 95% confidence interval.

RESULTS

Eight trials involving 331 patients were included in the meta-analysis, and the results showed a relief of pain (standardized mean difference = -0.65, 95% confidence interval = -1.16 to -0.14) and physical function (standardized mean difference = 0.63, 95% confidence interval = 0.17 to 1.09) after aquatic exercise. However, there was no significant effectiveness with regard to general mental health in aquatic group (standardized mean difference = 0.46; 95% confidence interval = -0.22 to 1.15).

CONCLUSIONS

Aquatic exercise can statistically significantly reduce pain and increase physical function in patients with low back pain. Further high-quality investigations on a larger scale are required to confirm the results.

Development of culturally sensitive Pain Neuroscience Education for first-generation Turkish patients with chronic pain: A modified Delphi study

BACKGROUND

Pain Neuroscience Education (PNE) has been recognized as an efficacious approach for chronic pain, but evidence for these findings have mainly been gathered in Caucasian patient populations. In recent years, it has been proposed that the treatment of pain and patient information materials should be culturally sensitive for different ethnic populations and cultures since cultural variations in pain beliefs and cognitions.

OBJECTIVES

To culturally adapt PNE material for first-generation Turkish patients with chronic pain.

DESIGN

A modified Delphi study with three consecutive rounds.

METHOD

A total of 10 participants (8 experts and 2 first-generation Turkish patients with chronic pain) were recruited for this study. Three online questionnaire rounds were conducted to synthesize the perspectives and to reach agreement on the suggested PNE materials.

RESULTS

Results on multiple-choice questions from the first round revealed that the compatibility of the visual information and the clarity of the message obtained lower scores. Examples, visual information (illustrations, pictures), and metaphors in the teaching materials and the home education leaflet were revised based on suggestions in Rounds 1 and 2. In Round 3, respondents reached an acceptable agreement level for the clinical usefulness of the PNE teaching materials and the home education material.

CONCLUSIONS

Culturally sensitive PNE materials were produced for first-generation Turkish patients. Since the results of the present study only reveal perspectives of the experts, further validation of education materials may be required before they are recommended for Turkish patients in clinical practices.

Application of Pilates-based exercises in the treatment of chronic non-specific low back pain: state of the art

According to the current recommendations on the management of chronic non-specific low back pain (CNLBP), the intervention in this group of patients should include a programme of exercises. Pilates is a system of exercises widely used in patients with low back pain. The practices based on this method have promoted the restoration of the function of muscles involved in lumbopelvic stabilisation, that is, transversus abdominis, multifidus, diaphragm and pelvic floor muscles. During each exercise, specific principles of this method should be followed to restore or sustain the motor control of the lumbar spine and proper body posture. The aim of this study is to present the current state of knowledge concerning the application of Pilates method in the management of CNLBP as well as to define factors (eg, duration, frequency, exercises performed on a mat or specific equipment) influencing the effectiveness of Pilates in these individuals.

Core Training in Low Back Disorders: Role of the Pilates Method

The Pilates method is a system of exercises developed by Joseph Pilates, which emphasizes recruitment and strengthening of the core muscles, flexibility, and breathing, to promote stability and control of movement. Its focus bears similarity to current evidence-based exercise programs for low back disorders. Spinal stability is a function of three interdependent systems, osseoligamentous, muscular, and neural control; exercise addresses both the muscular and neural function. The "core" typically refers to the muscular control required to maintain functional stability. Prior research has highlighted the importance of muscular strength and recruitment, with debate over the importance of individual muscles in the wider context of core control. Though developed long before the current evidence, the Pilates method is relevant in this setting and clearly relates to current evidence-based exercise interventions. Current literature supports the Pilates method as a treatment for low back disorders, but its benefit when compared with other exercise is less clear.

Measures to assess the performance of an Australian non-government charitable non-acute health service: A Delphi Survey of Organisational Stakeholders

Organisation performance measurement is relevant for non-profit charitable organisations as they strive for security in an increasingly competitive funding environment. This study aimed to identify the priority measures and indicators of organisational performance of an Australian non-government charitable organisation that delivers non-acute health services. Seventy-seven and 59 participants across nine stakeholder groups responded to a two-staged Delphi technique study of a case study organisation. The stage one questionnaire was developed using information garnered through a detailed review of literature. Data from the first round were aggregated and analysed for the stage two survey. The final data represented a group consensus. Quality of care was ranked the most important of six organisational performance measures. Service user satisfaction was ranked second followed by financial performance, internal processes, employee learning and growth and community engagement. Thirteen priority indicators were determined across the six measures. Consensus was reached on the priority organisational performance measures and indicators. Stakeholders of the case study organisation value evidence-based practice, technical strength of services and service user satisfaction over more commercially orientated indicators.

Examining the postural awareness and flexibility changes in physical therapy students who took clinical Pilates class

Objective:

This study aimed to evaluate postural awareness and changes in posture and flexibility of students who took Clinical Pilates class as an elective course at the undergraduate level.

Methods:

The study conducted from 2013-2016 included 98 students who took Clinical Pilates class at the Department of Physical Therapy and Rehabilitation, School of Health Sciences, Istanbul Medipol University, Turkey. The flexibility levels of the study participants were measured before and after the Clinical Pilates education using finger-to-floor test and modified Schober’s test. Observational posture analysis and postural awareness were recorded using the scale prepared by the researchers.

Results:

The post-education evaluations showed that postural distortions were fixed, and a significant increase in the postural awareness of the students was observed compared with the pre-education period. The results of both modified Schober’s test and finger-to-floor test, which were used to measure the flexibility levels, showed a statistically significant increase in post-education scores compared with those of the pre-education period.

Conclusion:

This study showed that the Clinical Pilates course increased postural awareness and flexibility of physical therapy students and fixed postural distortions. Thus, the inclusion of Clinical Pilates class in the undergraduate education is considered to be important.

Effects of pilates on patients with chronic non-specific low back pain: a systematic review

[Purpose] To evaluate the effects of Pilates on patients with chronic low back pain through a systematic review of high-quality articles on randomized controlled trials. [Subjects and Methods] Keywords and synonyms for “Pilates” and “Chronic low back pain” were used in database searches. The databases included PubMed, Physiotherapy Evidence Database (PEDro), Medline, and the Cochrane Library. Articles involving randomized controlled trials with higher than 5 points on the PEDro scale were reviewed for suitability and inclusion. The methodological quality of the included randomized controlled trials was evaluated using the PEDro scale. Relevant information was extracted by 3 reviewers. [Results] Eight randomized controlled trial articles were included. Patients with chronic low back pain showed statistically significant improvement in pain relief and functional ability compared to patients who only performed usual or routine health care. However, other forms of exercise were similar to Pilates in the improvement of pain relief and functional capacity. [Conclusion] In patients with chronic low back pain, Pilates showed significant improvement in pain relief and functional enhancement. Other exercises showed effects similar to those of Pilates, if waist or torso movement was included and the exercises were performed for 20 cumulative hours.

A Systematic Review of the Effects of Exercise and Physical Activity on Non-Specific Chronic Low Back Pain

Back pain is a major health issue in Western countries and 60%–80% of adults are likely to experience low back pain. This paper explores the impact of back pain on society and the role of physical activity for treatment of non-specific low back pain. A review of the literature was carried out using the databases SPORTDiscuss, Medline and Google Scholar. A general exercise programme that combines muscular strength, flexibility and aerobic fitness is beneficial for rehabilitation of non-specific chronic low back pain. Increasing core muscular strength can assist in supporting the lumbar spine. Improving the flexibility of the muscle-tendons and ligaments in the back increases the range of motion and assists with the patient’s functional movement. Aerobic exercise increases the blood flow and nutrients to the soft tissues in the back, improving the healing process and reducing stiffness that can result in back pain.

Effectiveness and Cost-Effectiveness of Different Weekly Frequencies of Pilates for Chronic Low Back Pain: Randomized Controlled Trial

BACKGROUND

The Pilates method has been recommended to patients with low back pain, but the evidence on effectiveness is inconclusive. In addition, there is still no evidence for the cost-effectiveness of this method or for the ideal number of sessions to achieve the highest effectiveness.

OBJECTIVE

The aim of this study will be to investigate the effectiveness and cost-effectiveness of the Pilates method with different weekly frequencies in the treatment of patients with nonspecific low back pain.

DESIGN

This is a randomized controlled trial with blinded assessor.

SETTING

This study will be conducted at a physical therapy clinic in São Paulo, Brazil.

PARTICIPANTS

Two hundred ninety-six patients with nonspecific low back pain between the ages of 18 and 80 years will be assessed and randomly allocated to 4 groups (n=74 patients per group).

INTERVENTION

All groups will receive an educational booklet. The booklet group will not receive additional exercises. Pilates group 1 will follow a Pilates-based program once a week, Pilates group 2 will follow the same program twice a week, and Pilates group 3 will follow the same program 3 times a week. The intervention will last 6 weeks.

MEASUREMENTS

A blinded assessor will evaluate pain, quality-adjusted life-years, general and specific disability, kinesiophobia, pain catastrophizing, and global perceived effect 6 weeks, 6 months, and 12 months after randomization.

LIMITATIONS

Therapists and patients will not be blinded.

CONCLUSIONS

This will be the first study to investigate different weekly frequencies of treatment sessions for nonspecific low back pain. The results of this study will contribute to a better definition of treatment programs for this population.

The effectiveness of Pilates exercise in people with chronic low back pain: a systematic review

OBJECTIVE

To evaluate the effectiveness of Pilates exercise in people with chronic low back pain (CLBP) through a systematic review of randomised controlled trials (RCTs).

DATA SOURCES

A search for RCTs was undertaken using Medical Search Terms and synonyms for "Pilates" and "low back pain" within the maximal date range of 10 databases. Databases included the Cumulative Index to Nursing and Allied Health Literature; Cochrane Library; Medline; Physiotherapy Evidence Database; ProQuest: Health and Medical Complete, Nursing and Allied Health Source, Dissertation and Theses; Scopus; Sport Discus; Web of Science.

STUDY SELECTION

Two independent reviewers were involved in the selection of evidence. To be included, relevant RCTs needed to be published in the English language. From 152 studies, 14 RCTs were included.

DATA EXTRACTION

Two independent reviewers appraised the methodological quality of RCTs using the McMaster Critical Review Form for Quantitative Studies. The author(s), year of publication, and details regarding participants, Pilates exercise, comparison treatments, and outcome measures, and findings, were then extracted.

DATA SYNTHESIS

The methodological quality of RCTs ranged from "poor" to "excellent". A meta-analysis of RCTs was not undertaken due to the heterogeneity of RCTs. Pilates exercise provided statistically significant improvements in pain and functional ability compared to usual care and physical activity between 4 and 15 weeks, but not at 24 weeks. There were no consistent statistically significant differences in improvements in pain and functional ability with Pilates exercise, massage therapy, or other forms of exercise at any time period.

CONCLUSIONS

Pilates exercise offers greater improvements in pain and functional ability compared to usual care and physical activity in the short term. Pilates exercise offers equivalent improvements to massage therapy and other forms of exercise. Future research should explore optimal Pilates exercise designs, and whether some people with CLBP may benefit from Pilates exercise more than others.

Indications, benefits, and risks of Pilates exercise for people with chronic low back pain: a Delphi survey of Pilates-trained physical therapists

BACKGROUND

The effectiveness of Pilates exercise for treating people with chronic low back pain (CLBP) is yet to be established. Understanding how to identify people with CLBP who may benefit, or not benefit, from Pilates exercise and the benefits and risks of Pilates exercise will assist in trial design.

OBJECTIVES

The purpose of this study was to establish a consensus regarding the indications, contraindications, and precautions of Pilates exercise and the potential benefits and risks of Pilates exercise for people with CLBP.

METHODS

A panel of 30 Australian physical therapists experienced in the use of Pilates exercise were surveyed using the Delphi technique. Three electronic questionnaires were used to collect participant opinions. Answers to open-ended questions were analyzed thematically, combined with research findings, and translated into statements about Pilates exercise. Participants then rated their level of agreement with statements using a 6-point Likert scale. Consensus was achieved when 70% of panel members agreed or disagreed with an item.

RESULTS

Thirty physical therapists completed the 3 questionnaires. Consensus was reached on 100% of items related to the benefits, indications, and precautions of Pilates exercise, on 50% of items related to risks, and on 56% of items related to contraindications. Participants agreed that people who have poor body awareness and maladaptive movement patterns may benefit from Pilates exercise, whereas those with pre-eclampsia, unstable spondylolisthesis, or a fracture may not benefit. Participants also agreed that Pilates exercise may improve functional ability, movement confidence, body awareness, posture, and movement control.

LIMITATIONS

The findings reflect the opinions of only 30 Australian physical therapists and not all health professionals nationally or internationally. These findings, therefore, need to be verified in future research trials.

CONCLUSIONS

These findings contribute to a better understanding of the indications, contraindications, and precautions of Pilates exercise and the benefits and risks of Pilates exercise for people with CLBP. This information can assist in design of future trials examining the effectiveness of Pilates exercise.

Developing the principles of chair based exercise for older people: a modified Delphi study

BACKGROUND

Chair based exercise (CBE) is suggested to engage older people with compromised health and mobility in an accessible form of exercise. A systematic review looking at the benefits of CBE for older people identified a lack of clarity regarding a definition, delivery, purpose and benefits. This study aimed to utilise expert consensus to define CBE for older people and develop a core set of principles to guide practice and future research.

METHODS

The framework for consensus was constructed through a team workshop identifying 42 statements within 7 domains. A four round electronic Delphi study with multi-disciplinary health care experts was undertaken. Statements were rated using a 5 point Likert scale of agreement and free text responses. A threshold of 70% agreement was used to determine consensus. Free text responses were analysed thematically. Between rounds a number of strategies (e.g., amended wording of statements, generation and removal of statements) were used to move towards consensus.

RESULTS

16 experts agreed on 46 statements over four rounds of consultation (Round 1: 22 accepted, 3 removed, 5 new and 17 modified; Round 2: 16 accepted, 0 removed, 4 new and 6 modified; Round 3: 4 accepted, 2 removed, 0 new and 4 modified; Round 4: 4 accepted, 0 removed, 0 new, 0 modified).Statements were accepted in all seven domains: the definition of CBE (5), intended users (3), potential benefits (8), structure (12), format (8), risk management (7) and evaluation (3).The agreed definition of CBE had five components: 1. CBE is primarily a seated exercise programme; 2. The purpose of using a chair is to promote stability in both sitting and standing; 3. CBE should be considered as part of a continuum of exercise for frail older people where progression is encouraged; 4. CBE should be used flexibly to respond to the changing needs of frail older people; and 5. Where possible CBE should be used as a starting point to progress to standing programmes.

CONCLUSIONS

Consensus has been reached on a definition and a set of principles governing CBE for older people; this provides clarity for implementation and future research about CBE.
