Effectiveness of Pilates and Yoga to improve bone density in adult women: A systematic review and meta-analysis

BACKGROUND

The ageing population brings about the appearance of age-related health disorders, such as osteoporosis or osteopenia. These disorders are associated with fragility fractures. The impact is greater among postmenopausal women due to an acceleration of bone mineral density (BMD) loss.

OBJECTIVE

To estimate the effectiveness of Pilates or Yoga on BMD in adult women.

METHODS

Five electronics databases were searched up to April 2021. Randomized controlled trials (RCTs), non-RCTs and pre-post studies were included. The main outcome was BMD. Risk of bias was evaluated using the Cochrane risk of bias tool. A random effects model was used to pool data from primary studies. Subgroup analyses based on the type of exercise were conducted.

RESULTS

Eleven studies including 591 participants aged between 45 and 78 years were included. The mean length of the interventions ranged from 12 to 32 weeks, and two studies were performed for a period of at least one year. The pooled effect size for the effect of the intervention (Pilates/Yoga) vs the control group was 0.07 (95% Confidence interval [CI]: -0.05 to 0.19; I2 = 0.0%), and 0.10 (95% CI: 0.01 to 0.18; I2 = 18.4%) for the secondary analysis of the pre-post intervention.

CONCLUSIONS

Despite of the non-significant results, the BMD maintenance in the postmenopausal population, when BMD detrimental is expected, could be understood as a positive result added to the beneficial impact of Pilates-Yoga in multiple fracture risk factors, including but not limited to, strength and balance.

Pilates-based core exercise improves health-related quality of life in people living with chronic low back pain: A pilot study

PURPOSE

To investigate the effects of Pilates exercise on improving health-related quality of life in people living with chronic low back pain.

METHODS

This was a single-blind, randomised clinical trial. Thirty-nine physically active subjects aged between 30 and 70 years with nonspecific chronic low back pain for more than three months were recruited. The study employed a pretest-posttest design, with a 4 -, 8 -, and 26-week follow-up. For eight weeks, the intervention group participated in a group-supervised, mat-based Pilates program, while the control group received the usual pharmacologic and rehabilitation standard of care, including patient education on chronic low back pain. The primary outcome was self-perceived health status measured using the EQ-5D questionnaire in a structured form and a visual analogue scale. Secondary outcomes included intensity of pain and degree of disability.

RESULTS

By the end of the 8-week Pilates program, the intervention group achieved a better health-related quality of life on the EQ-5D visual analogue score than the control group. In assessing the trends in each individual group regarding pain, the intervention group demonstrated an earlier pain reduction than the control group that lasted until the end of the trial.

CONCLUSIONS

An 8-week supervised Pilates-based core exercise program is an effective therapeutic modality for improving self-perceived health status in patients with chronic low back pain. This finding could inform clinicians of better alternatives when they suggest exercise interventions for chronic low back pain.

Effect of Pilates Matwork exercises on posterior chain flexibility and trunk mobility in school children: A randomized clinical trial

OBJECTIVE

To investigate the effects of an exercise program, based on the Pilates Matwork method, on posterior chain flexibility and trunk mobility in healthy school age children.

DESIGN AND SETTING

The study was a parallel-group randomized clinical trial. The participants were randomly assigned to groups: Pilates Group (PG) and Control Group (CG). The program was developed at the Early Childhood Education Institute, Londrina-PR.

PARTICIPANTS

43 children with age between eight to 12 years, no prior knowledge of the Pilates method, and no exercise training in the last six months.

INTERVENTION

Four months of twice a week 50 min Pilates Matwork exercises were administered.

OUTCOME MEASURES

Flexibility and mobility, assessed using the sit-and-reach test, fingertip-to-floor test and photogrammetry. The assessors were blinded to the allocation of participants.

RESULTS

Three children were excluded before randomization and 40 were randomized (PG n = 20; CG n = 20).12 children were excluded during the protocol (PG n = 7; CG n = 5) and included in the intention to treat analysis. No significant difference between groups was observed for flexibility measures. There was a significant difference in the following outcomes for the PG: distance reached in the sit-and-reach test between pre-test (median 14.25[11.25-28.38]) and post-test (median 20.25[12.00-29.63]) (ES = 0.29, SRM = 0.73); Posterior angle of the knee in the fingertip-to-floor test between pre-test (median 191.60[187.20-191.60]) and post-test (median 189.00[185.90-191.50]) (ES = 0.56, SRM = 0.54).

CONCLUSION

There were no differences in posterior chain flexibility and trunk mobility between school age children who underwent Pilates Matwork exercises and the control. However, children who participated in the exercise program showed improvement in some results of flexibility.

Effect of mat vs. apparatus pilates training on the functional capacity of elderly women

INTRODUCTION

It is well known that physical exercise improves functional capacity (FC), promoting healthy aging. The Pilates method (PM) is an example of well-accepted physical exercise by the elderly and has been reported in studies to be beneficial for this population. However, it is not yet known whether there is a difference between the practice of mat and apparatus PM. The goal of this study was to compare the effect of mat versus apparatus Pilates training on functional capacity in elderly women.

METHOD

48 active elderly women (65.15 ± 3.0 years old), independent or partially independent in Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL), who had never practiced Pilates, were separated into three groups in a random order through a draw: Mat Group (MG = 15), Apparatus Group (AG = 16) and Control Group (CG = 17). Pilates training sessions were applied to MG and AG for 8 weeks, with two weekly sessions of 50 min. The FC of the three groups was evaluated by the Senior Fitness Test (SFT) battery, pre and post intervention.

RESULTS

There were improvements in lower and upper limb strength, aerobic endurance, lower and upper limb flexibility, and agility after the intervention in both groups, showing no significant differences when compared to mat and apparatus Pilates training (<0,05).

CONCLUSION

The mat and apparatus Pilates training provide significant and similar improvements in the functional capacity of elderly women.

Comparison of the effectiveness of pilates exercises, aerobic exercises, and pilates with aerobic exercises in patients with rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis (RA) is a rheumatic disease characterized by erosive synovitis and polyarthritis. Exercise is known to improve many symptoms in RA patients.

AIM

This study was designed to compare the effects of pilates exercises, aerobic exercises, and combined training including pilates with aerobic exercises on fatigue, depression, aerobic capacity, pain, sleep quality, and quality of life.

METHODS

Thirty voluntary RA patients were included in this study. Patients were divided into three groups equally, and treatment was applied to each group for 8 weeks. Pilates exercises were practiced to the first group, aerobic exercises were practiced to the second group, and combined training was performed to the third group. Fatigue, depression, aerobic capacity, pain, sleep quality, and quality of life were evaluated using Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI), 6-minute walk test (6MWT), McGill Pain Questionnaire- Short Form (MPQ-SF), Pittsburg Sleep Quality Index (PSQI), and Rheumatoid Arthritis Quality of Life (RAQoL), respectively.

RESULTS

The results of the present study showed significant improvements for the first group on fatigue, depression, aerobic capacity, and quality of life (p < 0.05). Improvements in all parameters except for pain were obtained for the second and third groups (p < 0.05). In addition, there was no statistically significant difference among the treatment groups in assessments (p > 0.05).

CONCLUSION

Pilates exercises may have similar effects to aerobic exercises in patients with RA. Addition of clinical pilates exercises to the routine treatment of RA may enhance the success of rehabilitation. Trial registration NCT03836820.

Hypoxic Pilates Intervention for Obesity: A Randomized Controlled Trial

This study examined the effect of Pilates training under hypoxia, a novel treatment method, for obesity. Thirty-two Korean women with obesity (age: 34–60 (47.5 ± 7.5) years) were randomly assigned to control (CON; n = 10), normoxic Pilates training (NPTG; n = 10), and hypoxic Pilates training groups (HPTG; n = 12). The NPTG and HPTG performed 50 min of Pilates training using a tubing band for 12 weeks (3 days/week) in their respective environmental conditions (NPTG: normoxic condition, inspired oxygen fraction (F_iO₂) = 20.9%; HPTG: moderate hypoxic condition, F_iO₂ = 14.5%). The CON maintained their daily lifestyle without intervention. All subjects underwent body composition, blood pressure, arterial stiffness, vascular endothelial function, cardiometabolic biomarker, hemorheological function, and aerobic performance measurements before and after the intervention. The HPTG showed a significant improvement in diastolic blood pressure, total cholesterol and triglyceride concentrations, flow-mediated dilation, and erythrocyte deformability and aggregation (all p < 0.05) compared with the CON and NPTG. However, compared with the CON and NPTG, the HPTG did not show improvement in other parameters. Hypoxic Pilates intervention is a novel and successful method for promoting endothelial and hemorheological functions in women with obesity.

Efficacy of the Pilates versus general exercises versus educational workshops on neuromuscular parameters: A randomized controlled trial

INTRODUCTION

Muscle strength, flexibility and changes in muscle recruitment patterns are usually associated to low back pain (LBP). Physical exercises can reverse the adverse changes associated to LBP.

OBJECTIVES

Compare Pilates, general exercises and educational workshop on muscle flexibility, strength and recruitment of the trunk extensor muscles in women with LBP.

METHODS

Forty-six women were randomly divided into Pilates group (PG, n = 16), general exercise group (GEG, n = 15), and educational group (EG, n = 15). This study sought to determine flexibility, muscle strength, and muscle recruitment of right (RIL), left (LIL) iliocostalis lumbar; right (RMU) and left (LMU) lumbar multifidus muscles. Both PG and GEG performed 16 exercise sessions, while EG attended 4 workshops. Statistical analysis used data sample from Shapiro-Wilk test, Pearson's correlation, multivariate analysis, mixed variance analysis, and Cohen's index.

RESULTS

Flexibility showed no differences (p > 0.05). Muscle strength increased in the intragroup analysis for PG (p = 0.003) and GEG (p = 0.002); however, the intergroup analysis presented no difference. Intergroup showed statistically significant differences for the recruitment of RMU in PG (p < 0.001). Intragroup analysis presented differences after interventions in PG for RIL (p = 0.001); in GEG for LIL (p = 0.005); and in EG for RIL (p = 0.007), LIL (p = 0.002) and RMU (p < 0.001).

CONCLUSIONS

None of the groups showed flexibility improvements. PG and GEG increased muscle strength through intragroup analysis. Intergroup analysis showed an increase in recruitment of the RMU muscle in PG and all groups demonstrated significant improvements in the intragroup analysis.

Effectiveness of A Pilates Training Program on Cognitive and Functional Abilities in Postmenopausal Women

The purpose of this study was to determine the effects of a Pilates exercises program on the cognitive and physical functioning of older Spanish women. This study is a randomized clinical trial; a total of 110 women aged ≥60 years were initially allocated to either a Pilates group (PG, n = 55), who underwent a 12-week Pilates exercise program, or to a control group (CG, n = 55), who did not receive any intervention. Global cognitive function (Mini-Mental State Examination), verbal fluency (Isaacs test), executive function (Trail Making Test), functional flexibility (Back Scratch Test and Chair Sit-and-Reach Test), and lower-body strength (30 s Chair-Stand Test) were assessed before and immediately after the intervention period. The main findings of this study suggest that women in the PG (within-group differences) experienced improvements across all the variables examined except for global cognitive function. When compared with the CG (between-group differences), our analysis revealed significant benefits in the PG for all measures except for global cognitive function and functional flexibility (Back Scratch Test). In conclusion, our results suggest that Pilates has the potential to improve both cognitive and functional abilities among Spanish women aged 60 years and over.

Physical activity interventions for adults who are visually impaired: a systematic review and meta-analysis

OBJECTIVES

Compared with sighted individuals, people with visual impairment have a higher prevalence of chronic conditions and lower levels of physical activity. This review aims to systematically review physical activity interventions for those with a visual impairment and to assess their effectiveness.

DESIGN

A systematic review of articles reporting physical activity interventions in visually impaired individuals was conducted. Medline, EMBASE, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus and the Physiotherapy Evidence Database were searched in August 2018. Meta-analyses were conducted on randomised controlled trials with the same outcome measure.

SETTING

Most interventions were conducted in a group setting, with some including an at-home, self-directed component.

PARTICIPANTS

Following identification of a recent systematic review of physical activity interventions in children, our review focused on adults aged 18 years and older with a visual impairment.

PRIMARY AND SECONDARY OUTCOME MEASURES

Outcomes included measures of balance, mobility, mental well-being (eg, quality of life), number of falls, muscle strength, flexibility and gait.

RESULTS

Eighteen papers from 17 studies met inclusion criteria. Physical activity components include falls prevention and/or balance-based activities, walking, tai chi, Alexander Technique, Yoga, dance, aerobics and core stability training. Significant results in favour of the intervention were reported most commonly in measures of functional capacity (9/17 studies) and in falls/balance-related outcomes (7/13 studies). The studies identified were generally small and diverse in study design, and risk of bias was high across several categories for most studies. Meta-analyses indicated non-significant effects of the included interventions on the Timed Up and Go, Chair Sit Test and Berg Balance Scale.

CONCLUSIONS

Physical activity interventions in individuals with visual impairment incorporating activities such as tai chi, Yoga and dance can have positive results, particularly in physical measures such as mobility and balance. However, when performing a meta-analysis of randomised controlled trials, the evidence for effectiveness is less clear. More studies with larger sample sizes, stronger designs and longer follow-up periods are needed.

Effects of traditional Chinese exercise on lumbar disc herniation: A protocol of network meta-analysis of randomized controlled trials

BACKGROUND

A large number of randomized controlled trials (RCTs) have shown that traditional Chinese exercises (TCE) have certain advantages in the treatment of lumbar disc herniation (LDH). However, due to the diversity of TCE methods, their relative effectiveness has not been studied and explained. Therefore, based on the network meta-analysis (NMA), this study will compare the differences in the effectiveness of TCE methods in the treatment of LDH, in order to provide a reference for clinical treatment.

METHODS

We will search PubMed, MEDLINE, Embase, the Cochrane Library, China National Knowledge Infrastructure (CHKD-CNKI), WANFANG database (Chinese Medicine Premier), Chinese Biomedical Literature database VIP for relevant RCTs of ACU treatments for POP, from their inceptions to March 18, 2019. STATA 15.0 and GEMTC software will be used to perform a NMA. The evidence will be evaluated by the Grading of Recommendations Assessment, Development, and Evaluation approach and the type 1 error rate will be assessed by trial sequential analysis.

RESULTS

The results of this review will be submitted to a recognized journal for publication.

CONCLUSION

This proposed systematic review will evaluate the different advantages of various types of TCE in the treatment of LDH.

Electromyographic characteristics of pelvic floor muscles in women with stress urinary incontinence following sEMG-assisted biofeedback training and Pilates exercises

The aim of this study was to compare the effect of pelvic floor muscle training with surface electromyographic (sEMG) biofeedback (BF group) and Pilates exercises (P group) on the bioelectrical activity of pelvic floor muscles in women with stress urinary incontinence. The other aim aim was to compare changes in voiding diaries and scores on quality of life questionnaire against baseline values and between the groups. Women in the BF group (n = 18) participated in pelvic floor muscle training with sEMG biofeedback; the P group (n = 13) participated in basic level Pilates workouts. Both protocols were continued for eight weeks. Voiding diary, quality of life and electromyographic characteristics of the pelvic floor muscles were assessed at the three-time points: at baseline, after eight weeks’ training, and at month six post-training. The sEMG activity of the pelvic floor muscles was tested during five trials in two positions. There was no marked improvement in bioelectrical activity of the pelvic floor muscles during contraction following training with sEMG biofeedback or Pilates exercises. Following eight weeks of sEMG biofeedback training, a decrease was noted in resting bioelectrical activity of pelvic floor muscles and during relaxation after sustained contraction but only in supine-lying. No such effect was observed in the Pilates group. In the BF group, the number of incontinence episodes after end of treatment (timpepoints: 1vs. 2) and at six month follow-up (timpepoints: 1vs. 3) decreased by 68.5% and 89.3%, respectively. The respective values in the P group were 78.6%, and 86.4%. The intergroup differences did not reach the level of statistical significance. As regards the quality of life, the questionnaire demonstrated that Pilates exercises had significantly better effects compared to biofeedback training both at the end of the eight-week exercise program and (p = 0.003) and at six month follow-up (p = 0.0009). The International Consultation on Incontinence Questionnaire—Short Form (ICIQ- SF) showed comparable efficacy of Pilates exercises and training with sEMG biofeedback. Intragroup improvements in micturition frequency, incontinence (leakage) episodes, and nocturia frequency were comparable. Alleviation of urinary incontinence symptoms was comparable in both groups, whereas the improvement in the quality of life was more notable in the Pilates group. The obtained results failed to demonstrate the superiority of any of the two methods regarding the bioelectrical activity of pelvic floor muscles in patients with stress urinary incontinence.

Tai Chi for rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory, autoimmune disease that results in joint deformity and immobility of the musculoskeletal system. The major goals of treatment are to relieve pain, reduce inflammation, slow down or stop joint damage, prevent disability, and preserve or improve the person's sense of well-being and ability to function. Tai Chi, interchangeably known as Tai Chi Chuan, is an ancient Chinese health-promoting martial art form that has been recognized in China as an effective arthritis therapy for centuries. This is an update of a review published in 2004.

OBJECTIVES

To assess the benefits and harms of Tai Chi as a treatment for people with rheumatoid arthritis (RA).

SEARCH METHODS

We updated the search of CENTRAL, MEDLINE, Embase, and clinical trial registries from 2002 to September 2018.

SELECTION CRITERIA

We selected randomized controlled trials and controlled clinical trials examining the benefits (ACR improvement criteria or pain, disease progression, function, and radiographic progression), and harms (adverse events and withdrawals) of exercise programs with Tai Chi instruction or incorporating principles of Tai Chi philosophy. We included studies of any duration that included control groups who received either no therapy or alternate therapy.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

Adding three studies (156 additional participants) to the original review, this update contains a total of seven trials with 345 participants. Participants were mostly women with RA, ranging in age from 16 to 80 years, who were treated in outpatient settings in China, South Korea, and the USA. The majority of the trials were at high risk of bias for performance and detection bias, due to the lack of blinding of participants or assessors. Almost 75% of the studies did not report random sequence generation, and we judged the risk of bias as unclear for allocation concealment in the majority of studies. The duration of the Tai Chi programs ranged from 8 to 12 weeks.It is uncertain whether Tai Chi-based exercise programs provide a clinically important improvement in pain among Tai Chi participants compared to no therapy or alternate therapy. The change in mean pain in control groups, measured on visual analog scale (VAS 0 to 10 score, reduced score means less pain) ranged from a decrease of 0.51 to an increase of 1.6 at 12 weeks; in the Tai Chi groups, pain was reduced by a mean difference (MD) of -2.15 (95% confidence interval (CI) -3.19 to -1.11); 22% absolute improvement (95% CI, 11% to 32% improvement); 2 studies, 81 participants; very low-quality evidence, downgraded for imprecision, blinding and attrition bias.There was very low-quality evidence, downgraded for, blinding, and attrition, that was inconclusive for an important difference in disease activity, measured using Disease Activity Scale (DAS-28-ESR) scores (0 to 10 scale, lower score means less disease activity), with no change in the control group and 0.40 reduction (95% CI -1.10 to 0.30) with Tai Chi; 4% absolute improvement (95% CI 11% improvement to 3% worsening); 1 study, 43 participants.For the assessment of function, the change in mean Health Assessment Questionnaire (HAQ; 0 to 3 scale, lower score means better function) ranged from 0 to 0.1 in the control group, and reduced by MD 0.33 in the Tai Chi group (95% CI -0.79 to 0.12); 11% absolute improvement (95% CI 26% improvement to 4% worsening); 2 studies, 63 participants; very low-quality evidence, downgraded for imprecision, blinding, and attrition. We are unsure of an important improvement, as the results were inconclusive.Participants in Tai Chi programs were less likely than those in a control group to withdraw from studies at 8 to 12 weeks (19/180 in intervention groups versus 49/165 in control groups; risk ratio (RR) 0.40 (95% CI 0.19 to 0.86); absolute difference 17% fewer (95% CI 30% fewer to 3% fewer); 7 studies, 289 participants; low-quality evidence, downgraded for imprecision and blinding.There were no data available for radiographic progression. Short-term adverse events were not reported by group, but in two studies there was some narrative description of joint and muscle soreness and cramps; long-term adverse events were not reported.

AUTHORS' CONCLUSIONS

It is uncertain whether Tai Chi has any effect on clinical outcomes (joint pain, activity limitation, function) in RA, and important effects cannot be confirmed or excluded, since all outcomes had very low-quality evidence. Withdrawals from study were greater in the control groups than the Tai Chi groups, based on low-quality evidence. Although the incidence of adverse events is likely to be low with Tai Chi, we are uncertain, as studies failed to explicitly report such events. Few minor adverse events (joint and muscle soreness and cramps) were described qualitatively in the narrative of two of the studies. This updated review provides minimal change in the conclusions from the previous review, i.e. a pain outcome.

The influence of the Pilates method on quality of life and bone remodelling in older women: a controlled study

PURPOSE

The objective of this study was to evaluate the effects of the Pilates method on quality of life and bone remodeling markers in a group of older women.

METHODS

A longitudinal prospective study with intervention was performed on 40 women aged over 60 years; they were divided into two groups: one submitted to a 50-min Pilates exercise session once a week for 20 weeks (Pilates), and the other was not (Control). Both groups were compared for quality of life using the Medical Outcomes Study 36, and for bone-specific alkaline phosphatase (BSAP) and Type 1 collagen C-telopeptide (CTx) bone remodeling markers.

RESULTS

The Pilates group presented improvement in the quality of life evaluation scores: physical functioning (67.50 ± 18.88 × 86.25 ± 9.58; p = 0.0232), and physical component summary (65.00 ± 14.39 × 79.70 ± 3.83; p = 0.0220). The Pilates group also presented higher scores than that of Controls after the exercise program: physical functioning (86.25 ± 9.58 × 55.50 ± 20.83, p = 0.0003), physical role (100.00 ± 0.00 × 41.25 ± 46.79, p = 0.0009), emotional role (100.00 ± 0.00 × 48.33 ± 50.12, p = 0.0046), vitality (82.50 ± 14.28 × 60.25 ± 21.43, p = 0.011), physical component summary (79.70 ± 3.83 × 54.90 ± 15.05, p < 0.0001), and emotional component summary (74.10 ± 8.37 × 54.18 ± 22.55, p = 0.0111). No changes were noted in bone remodeling markers [CTx (0.39 ± 0.26 × 0.38 ± 0.22 ng/mL) and BSAP (10.73 ± 2.40 × 11.01 ± 3.56 μg/L)] and did not differ from the Control group both before (CTx: 0.39 ± 0.26 × 0.37 ± 0.17 ng/mL; BSAP: 10.73 ± 2.40 × 10.58 ± 3.49 μg/L; p > 0.05) and after exercise (CTx: 0.38 ± 0.22 × 0.38 ± 0.22 ng/mL; BSAP: 11.01 ± 3.56 × 9.85 ± 3.12 μg/L; p > 0.05).

CONCLUSION

The group of women submitted to Pilates presented improved quality of life but without changes in bone remodeling.

One Year of Pilates Training for Ankylosing Spondylitis: A Pilot Study

Objectives: This prospective long-term study examines the effects of a Pilates training intervention on spinal mobility, disease activity, and functional capacity in patients with ankylosing spondylitis (AS). Design: The study design was quasi experimental and single blind. Subjects: 11 subjects were recruited among patients undergoing followup of AS diagnosed according to modified New York criteria at the rheumatology clinic. Interventions: Over a 12-month period, 11 patients completed a training program consisting of two sessions per week of selected Pilates exercises. There was no control group. Outcome measures: The primary outcome variable was functional capacity measured using the Bath Ankylosing Spondylitis Functional Index (BASFI) questionnaire. Exploratory outcome measures were Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Metrology Index (BASMI), and chest expansion and fingertip-to-floor (FTF) test. Baseline and follow-up examinations were performed immediately before the intervention and during the course of treatment at 4, 8, and 12 months. Results: After the exercise intervention, improvements were observed in BASFI (77.51%), BASDAI (64.39%) and BASMI (58.95%) scores, FTF distance (71.92%), and chest expansion (88.74%). Conclusions: These findings suggest that Pilates training could be useful in AS patients and provide direction for larger controlled trials designed to determine the therapeutic benefits of Pilates in the management of these patients.

Effects of Focal Vibration and Robotic Assistive Therapy on Upper Limb Spasticity in incomplete Spinal Cord Injury

Vibration stimulation seems to be an affordable easy-to-use rehabilitation tool. Focal muscle vibration (FV) has potential to reduce spasticity and enhance muscle strength and performance. Combined with robotic assisted movement therapy, the rehabilitation can benefit from improvement of more than one aspect. For example, FV could firstly decrease abnormally increased muscle tone and joint rigidity by tackling volitional control for easier robotic movement exercise. Exactly this approach is evaluated within a clinical trial presented in this paper. FV were applied to relaxed spastic wrist flexor and extensor muscles for 15min. Subsequently, the wrist was engaged in a robotic-assisted game-playing. Results from two cases who completed the trial showed short-term decrease in wrist stiffness as assessed by clinical spasticity measurement Modified Ashworth Scale (MAS). Active range of motion (AROM) and engineering joint stiffness (JS) measurements were estimated using a robotic apparatus and the results complemented previous observations. The AROM increased and JS decreased for both cases when compared at the beginning and at the end of each interventional session. These results are a part of an ongoing clinical trial but show promise for reducing repercussions of spasticity in incomplete spinal cord injury.

Mixed exercise training for adults with fibromyalgia

BACKGROUND

Exercise training is commonly recommended for individuals with fibromyalgia. This review is one of a series of reviews about exercise training for fibromyalgia that will replace the review titled "Exercise for treating fibromyalgia syndrome", which was first published in 2002.

OBJECTIVES

To evaluate the benefits and harms of mixed exercise training protocols that include two or more types of exercise (aerobic, resistance, flexibility) for adults with fibromyalgia against control (treatment as usual, wait list control), non exercise (e.g. biofeedback), or other exercise (e.g. mixed versus flexibility) interventions.Specific comparisons involving mixed exercise versus other exercises (e.g. resistance, aquatic, aerobic, flexibility, and whole body vibration exercises) were not assessed.

SEARCH METHODS

We searched the Cochrane Library, MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Thesis and Dissertations Abstracts, the Allied and Complementary Medicine Database (AMED), the Physiotherapy Evidence Databese (PEDro), Current Controlled Trials (to 2013), WHO ICTRP, and ClinicalTrials.gov up to December 2017, unrestricted by language, to identify all potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) in adults with a diagnosis of fibromyalgia that compared mixed exercise interventions with other or no exercise interventions. Major outcomes were health-related quality of life (HRQL), pain, stiffness, fatigue, physical function, withdrawals, and adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion, extracted data, and assessed risk of bias and the quality of evidence for major outcomes using the GRADE approach.

MAIN RESULTS

We included 29 RCTs (2088 participants; 98% female; average age 51 years) that compared mixed exercise interventions (including at least two of the following: aerobic or cardiorespiratory, resistance or muscle strengthening exercise, and flexibility exercise) versus control (e.g. wait list), non-exercise (e.g. biofeedback), and other exercise interventions. Design flaws across studies led to selection, performance, detection, and selective reporting biases. We prioritised the findings of mixed exercise compared to control and present them fully here.Twenty-one trials (1253 participants) provided moderate-quality evidence for all major outcomes but stiffness (low quality). With the exception of withdrawals and adverse events, major outcome measures were self-reported and expressed on a 0 to 100 scale (lower values are best, negative mean differences (MDs) indicate improvement; we used a clinically important difference between groups of 15% relative difference). Results for mixed exercise versus control show that mean HRQL was 56 and 49 in the control and exercise groups, respectively (13 studies; 610 participants) with absolute improvement of 7% (3% better to 11% better) and relative improvement of 12% (6% better to 18% better). Mean pain was 58.6 and 53 in the control and exercise groups, respectively (15 studies; 832 participants) with absolute improvement of 5% (1% better to 9% better) and relative improvement of 9% (3% better to 15% better). Mean fatigue was 72 and 59 points in the control and exercise groups, respectively (1 study; 493 participants) with absolute improvement of 13% (8% better to 18% better) and relative improvement of 18% (11% better to 24% better). Mean stiffness was 68 and 61 in the control and exercise groups, respectively (5 studies; 261 participants) with absolute improvement of 7% (1% better to 12% better) and relative improvement of 9% (1% better to 17% better). Mean physical function was 49 and 38 in the control and exercise groups, respectively (9 studies; 477 participants) with absolute improvement of 11% (7% better to 15% better) and relative improvement of 22% (14% better to 30% better). Pooled analysis resulted in a moderate-quality risk ratio for all-cause withdrawals with similar rates across groups (11 per 100 and 12 per 100 in the control and intervention groups, respectively) (19 studies; 1065 participants; risk ratio (RR) 1.02, 95% confidence interval (CI) 0.69 to 1.51) with an absolute change of 1% (3% fewer to 5% more) and a relative change of 11% (28% fewer to 47% more). Across all 21 studies, no injuries or other adverse events were reported; however some participants experienced increased fibromyalgia symptoms (pain, soreness, or tiredness) during or after exercise. However due to low event rates, we are uncertain of the precise risks with exercise. Mixed exercise may improve HRQL and physical function and may decrease pain and fatigue; all-cause withdrawal was similar across groups, and mixed exercises may slightly reduce stiffness. For fatigue, physical function, HRQL, and stiffness, we cannot rule in or out a clinically relevant change, as the confidence intervals include both clinically important and unimportant effects.We found very low-quality evidence on long-term effects. In eight trials, HRQL, fatigue, and physical function improvement persisted at 6 to 52 or more weeks post intervention but improvements in stiffness and pain did not persist. Withdrawals and adverse events were not measured.It is uncertain whether mixed versus other non-exercise or other exercise interventions improve HRQL and physical function or decrease symptoms because the quality of evidence was very low. The interventions were heterogeneous, and results were often based on small single studies. Adverse events with these interventions were not measured, and thus uncertainty surrounds the risk of adverse events.

AUTHORS' CONCLUSIONS

Compared to control, moderate-quality evidence indicates that mixed exercise probably improves HRQL, physical function, and fatigue, but this improvement may be small and clinically unimportant for some participants; physical function shows improvement in all participants. Withdrawal was similar across groups. Low-quality evidence suggests that mixed exercise may slightly improve stiffness. Very low-quality evidence indicates that we are 'uncertain' whether the long-term effects of mixed exercise are maintained for all outcomes; all-cause withdrawals and adverse events were not measured. Compared to other exercise or non-exercise interventions, we are uncertain about the effects of mixed exercise because we found only very low-quality evidence obtained from small, very heterogeneous trials. Although mixed exercise appears to be well tolerated (similar withdrawal rates across groups), evidence on adverse events is scarce, so we are uncertain about its safety. We downgraded the evidence from these trials due to imprecision (small trials), selection bias (e.g. allocation), blinding of participants and care providers or outcome assessors, and selective reporting.

Efficacy of virtual reality to reduce chronic low back pain: Proof-of-concept of a non-pharmacological approach on pain, quality of life, neuropsychological and functional outcome

Objectives

Chronic pain, such as low-back pain, can be a highly disabling condition degrading people’s quality of life (QoL). Not every patient responds to pharmacological therapies, thus alternative treatments have to be developed. The chronicity of pain can lead to a somatic dysperception, meaning a mismatch between patients’ own body perception and its actual physical state. Since clinical evaluation of pain relies on patients’ subjective reports, a body image disruption can be associated with an incorrect pain rating inducing incorrect treatment and a possible risk of drug abuse. Our aim was to reduce chronic low-back pain through a multimodal neurorehabilitative strategy using innovative technologies to help patients regain a correct body image.

Methods

Twenty patients with chronic low-back pain were included. Before and after treatment, patients underwent: a neurological exam; a neuro-psychological evaluation testing cognitive functions (memory, attention, executive functions) and personality traits, QoL and mood; pain ratings; sensorimotor functional abilities’ testing. Patients underwent a 6 week-neurorehabilitative treatment (total 12 sessions) using virtual reality (VRRS system, Khymeia, Italy). Treatment consisted on teaching patients to execute correct movements with the painful body parts to regain a correct body image, based on the augmented multisensory feedback (auditory, visual) provided by the VRRS.

Results

Our data showed significant reductions in all pain rating scale scores (p<0.05); significant improvements of QoL in the domains of physical functioning, physical role functioning, bodily pain, vitality, and social role functioning; improvements in cognitive functions (p<0.05); improvements in functional scales (p<0.05) and mood (p = 0.04).

Conclusion

This non-pharmacological approach was able to act on the multi-dimensional aspects of pain and improved patients’ QoL, pain intensity, mood and patient’s functional abilities.

Neuromuscular efficiency of the multifidus muscle in pilates practitioners and non-practitioners

BACKGROUND

Pilates exercises help stabilize the vertebral segments by recruiting the abdominal and spinal muscles. Pilates training may increase joint stability and improve neuromuscular efficiency (NME).

OBJECTIVE

This study aimed to evaluate NME of the multifidus (MU) muscle through electromyography (EMG) analysis and torque test, applied to practitioners and non-practitioners of Pilates.

METHODS

Participants included thirty women: Pilates practitioners (n = 15) and non-practitioners (n = 15). They were tested for trunk extension. Their right and left MU muscles were submitted to EMG to estimate NME. Results concerning torque, EMG, and NME from all participants were compared.

RESULTS

Statistical analysis concerning isometric torque peak (p = 0.0275) and NME (p = 0.0062) showed significant difference (Student t test; p < 0.05) between practitioners and control. No significant difference (p = 0.3387) in EMG was observed.

CONCLUSION

Our results suggest Pilates exercises is effective in training spinal muscles to improve NME in women.

Pilates in noncommunicable diseases: A systematic review of its effects

OBJECTIVES

Chronic cardiovascular diseases, cancer, chronic respiratory diseases and diabetes are the four major groups of non-communicable diseases (NCDs) and the main cause of mortality worldwide. Pilates has been described as an effective intervention to promote healthy behaviors and physical activity in people with chronic diseases. However, the evidence of its effects in NCDs have not been systematized. We investigated the effects of Pilates in the four major groups of NCDs.

DESIGN

A systematic review was performed. Searches were conducted on Cochrane Library, EBSCO, PubMed, Science Direct, Scopus and Web of Science databases. Studies were rated with the quality assessment tool for quantitative studies. As a meta-analysis was not possible to conduct, a best-evidence synthesis was used.

RESULTS

Twelve studies, mostly of moderate quality, were included with 491 participants (78.6% females; age range 13-70 years old) with breast cancer (n = 3), diabetes (n = 3), chronic stroke (2 years post stroke) (n = 2), chronic obstructive pulmonary disease (n = 1), cystic fibrosis (n = 1), heart failure (n = 1) and arterial hypertension (n = 1). The best-evidence synthesis revealed strong evidence for improving exercise tolerance; moderate evidence for improving symptoms, muscle strength and health-related quality of life and limited or conflicting evidence on vital signs, metabolic parameters, body composition, respiratory function, functional status, balance, flexibility and social support.

CONCLUSIONS

Pilates should be considered for patients with NCDs, as it improves exercise tolerance. Future studies with robust methodologies are still needed to clarify its effectiveness on outcomes with moderate, limited or conflicting evidence and to establish the most suitable intervention protocol.

[The comparative analysis of the influence of the supervised exercise training and home-based exercise training on the psychological status of the following coronary artery bypass grafting]

This article was designed to report the results of the comparative analysis of the influence of the home-based exercise training (HBT) and the supervised exercise training in the form of the controlled training (CVT) under conditions of outpatient rehabilitative treatment on the patients' quality of life (QoL) and psychological status (including manifestations of anxiety and depression) following coronary artery bypass grafting (CABG).

AIM

The objective of the present study was to evaluate the consequences of the application of different programs of physical rehabilitation under the outpatient conditions on the psychoemotional status and quality of life of the patients who had undergone coronary artery bypass grafting.

MATERIALS AND METHODS

A total of 114 male patients suffering from coronary artery disease (CAD) who had undergone CABG were available for the examination. All the patients were allocated to three groups. Group 1 was comprised of the patients (n=36) treated with the use of the supervised cycling training (SCT) while group 2 consisted of the patients who had to perform home-based walking training (HBWT) (n=36). The group of comparison included 42 patients. The psychophysiological assessment was carried out based on the Beck Depression Inventory (BDI) and the Spielberger-Hanin Personal and Reactive Anxiety Scale. The quality of life (QoL) was assessed with the use of the SF-36 questionnaire. All the patients were examined prior to surgery, 1.4 months and 1 year after CABG.

RESULTS

The study has demonstrated the most pronounced improvement in the quality of life of the patients following the 3-month supervised cycling training after CABG that was manifested as the decrease of anxiety and depression. The minimal changes in the psychological and emotional status were documented in the absence of any exercise training integrated into the postoperative rehabilitation program. Only the moderate improvement of QoL was observed in the patients treated with the application of the 3-month home-based walking training program after CABG. The positive effects of the three-month exercise training were evened out within 1 year after its initiation.

DISCUSSION

It has been shown that the effectiveness of HBT is somewhat lower than that of CVT in terms of the influence on the psychoemotional status of the patients following CABG. This finding is at variance with the results reported by the foreign authors and should provide a basis for the enhancement of the effectiveness of the post-CABG rehabilitation programs to be implemented under conditions of the medical facilities, their principal objective being the education of the patients in safe and efficient methods for the pots-surgical self-rehabilitation with the emphasis placed on the measures intended for the improvement of the approaches to monitoring the compliance of the patients with the prescribed recommendations and for increasing their motivation to observe as long as possible the advices given by the health care professionals.

CONCLUSION

The home-based walking training of moderate intensity provides a safe, easy to perform, and readily available tool for a large number of patients who underwent coronary artery bypass grafting even though it is somewhat less effective than the supervised cycling training. The effects of both rehabilitation modalities are rather short-term.

Breaking up sedentary time with seated upper body activity can regulate metabolic health in obese high-risk adults: A randomized crossover trial

AIMS

To investigate the impact of performing short bouts of seated upper body activity on postprandial blood glucose and insulin levels during prolonged sitting.

METHODS

Participants undertook two 7.5-hour experimental conditions in randomized order: (1) prolonged sitting only and (2) sitting, interspersed with 5 minutes of seated arm ergometry every 30 minutes. Blood samples were obtained while fasting and throughout the postprandial period after ingestion of two standardized meals. The incremental area under the curve (iAUC) was calculated for glucose and insulin throughout each experimental condition. A paired samples t-test was used to assess the difference in iAUC data between conditions for glucose (primary outcome) and insulin (secondary outcome).

RESULTS

Thirteen obese adults (7 women, 6 men; mean ± standard deviation [s.d.] age: 66 ± 6 years; body mass index 33.8 ± 3.8 kg/m² ) completed this investigation. Compared with the prolonged sitting-only condition, the implementation of seated arm ergometry every 30 minutes significantly reduced mean blood glucose iAUC (from 7.4 mmol/L/h [95% confidence interval {CI} 5.2, 9.5] to 3.1 mmol/L/h [95% CI 1.3, 5.0]; P = .001). Significant reductions in mean insulin iAUC (from 696 mU/L/h [95% CI 359, 1032] to 554 mU/L/h [95% CI 298, 811]; P = .047) were also observed.

CONCLUSION

Performing short bouts of arm ergometry during prolonged sitting attenuated postprandial glycaemia despite maintaining a seated posture. This may have clinical significance for those with weight-bearing difficulty who may struggle with postural change.

Effectiveness of a physical activity programme based on the Pilates method in pregnancy and labour

OBJECTIVE

To assess the effectiveness and safety of a physical activity programme based on use of the Pilates method, over eight weeks in pregnant women, on functional parameters, such as weight, blood pressure, strength, flexibility and spinal curvature, and on labour parameters, such as, type of delivery, episiotomy, analgesia and newborn weight.

METHOD

A randomized clinical trial was carried out on pregnant women, applying a programme of physical activity using the Pilates method, designed specifically for this population. A sample consisting of a total of 105 pregnant women was divided into two groups: intervention group (n=50) (32.87±4.46 years old) and control group (n=55) (31.52±4.95 years old). The intervention group followed a physical activity programme based on the Pilates method, for 2 weekly sessions, whereas the control group did not follow the program.

RESULTS

Significant improvements (p<0.05) in blood pressure, hand grip strength, hamstring flexibility and spinal curvature, in addition to improvements during labour, decreasing the number of Caesareans and obstructed labour, episiotomies, analgesia and the weight of the newborns were found at the end of the intervention.

CONCLUSION

A physical activity programme of 8 weeks based on the Pilates method improves functional parameters in pregnant women and benefits delivery.

Participation trends in holistic movement practices: a 10-year comparison of yoga/Pilates and t'ai chi/qigong use among a national sample of 195,926 Australians

BACKGROUND

In recent decades, the evidence supporting the physical and mental health benefits of holistic movement practices such as yoga and t'ai chi have become increasingly established. Consequently, investigating the participation prevalence and patterns of these practices is a relevant pursuit in the public health field. Few studies have provided population-level assessment of participation rates, however, and even fewer have focused on patterns over time. The purpose of this study was to examine participation prevalence and trends in yoga/Pilates and t'ai chi/qigong over a ten-year period in a nationally representative sample of Australians aged 15 years and over, with particular attention to sex and age. A secondary purpose was to juxtapose these findings with participation trends in traditional fitness activities over the same period.

METHODS

Data comprised modes and types of physical activity, age, and sex variables collected through the Exercise, Recreation and Sport Survey (ERASS), a series of independent cross-sectional Australia-wide surveys conducted yearly between 2001 and 2010. For each year, weighted population estimates were calculated for those participating in yoga/Pilates, t'ai chi/qigong, and fitness activities (e.g. aerobics, calisthenics). Linear regression and multiple logistic regression analyses were used to examine trends in prevalence rates over time and differences among sex and age (15-34; 35-54; 55+ years) groups, respectively.

RESULTS

Average prevalence rates between 2001 and 2010 were 3.0% (95% CI 2.9-3.1) for yoga/Pilates, 0.6% (95% CI 0.5-0.6) for t'ai chi/qigong, and 19.2% (95% CI 18.9-19.4) for fitness activities. Across the decade, overall participation rates remained relatively stable for yoga/Pilates and t'ai chi/qigong, while increasing linearly for fitness activities. For both genders and in all three age groups, participation in fitness activities increased, whereas only in the 55+ age group was there a significant increase in yoga/Pilates participation; participation in t'ai chi/qigong declined significantly in the two younger age groups.

CONCLUSIONS

Participation rates in yoga/Pilates and t'ai chi/qigong in Australia were low and relatively stable. As fitness activities increased in popularity across the decade, holistic movement practices did not. These findings point to the need to investigate activity-specific barriers and facilitators to participation, including intrapersonal, interpersonal, organisational, and environmental factors.

Physical activity and exercise for chronic pain in adults: an overview of Cochrane Reviews

BACKGROUND

Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning.Physical activity and exercise programmes are increasingly being promoted and offered in various healthcare systems, and for a variety of chronic pain conditions. It is therefore important at this stage to establish the efficacy and safety of these programmes, and furthermore to address the critical factors that determine their success or failure.

OBJECTIVES

To provide an overview of Cochrane Reviews of adults with chronic pain to determine (1) the effectiveness of different physical activity and exercise interventions in reducing pain severity and its impact on function, quality of life, and healthcare use; and (2) the evidence for any adverse effects or harm associated with physical activity and exercise interventions.

METHODS

We searched theCochrane Database of Systematic Reviews (CDSR) on the Cochrane Library (CDSR 2016, Issue 1) for systematic reviews of randomised controlled trials (RCTs), after which we tracked any included reviews for updates, and tracked protocols in case of full review publication until an arbitrary cut-off date of 21 March 2016 (CDSR 2016, Issue 3). We assessed the methodological quality of the reviews using the AMSTAR tool, and also planned to analyse data for each painful condition based on quality of the evidence.We extracted data for (1) self-reported pain severity, (2) physical function (objectively or subjectively measured), (3) psychological function, (4) quality of life, (5) adherence to the prescribed intervention, (6) healthcare use/attendance, (7) adverse events, and (8) death.Due to the limited data available, we were unable to directly compare and analyse interventions, and have instead reported the evidence qualitatively.

MAIN RESULTS

We included 21 reviews with 381 included studies and 37,143 participants. Of these, 264 studies (19,642 participants) examined exercise versus no exercise/minimal intervention in adults with chronic pain and were used in the qualitative analysis.Pain conditions included rheumatoid arthritis, osteoarthritis, fibromyalgia, low back pain, intermittent claudication, dysmenorrhoea, mechanical neck disorder, spinal cord injury, postpolio syndrome, and patellofemoral pain. None of the reviews assessed 'chronic pain' or 'chronic widespread pain' as a general term or specific condition. Interventions included aerobic, strength, flexibility, range of motion, and core or balance training programmes, as well as yoga, Pilates, and tai chi.Reviews were well performed and reported (based on AMSTAR), and included studies had acceptable risk of bias (with inadequate reporting of attrition and reporting biases). However the quality of evidence was low due to participant numbers (most included studies had fewer than 50 participants in total), length of intervention and follow-up (rarely assessed beyond three to six months). We pooled the results from relevant reviews where appropriate, though results should be interpreted with caution due to the low quality evidence. Pain severity: several reviews noted favourable results from exercise: only three reviews that reported pain severity found no statistically significant changes in usual or mean pain from any intervention. However, results were inconsistent across interventions and follow-up, as exercise did not consistently bring about a change (positive or negative) in self-reported pain scores at any single point. Physical function: was the most commonly reported outcome measure. Physical function was significantly improved as a result of the intervention in 14 reviews, though even these statistically significant results had only small-to-moderate effect sizes (only one review reported large effect sizes). Psychological function and quality of life: had variable results: results were either favourable to exercise (generally small and moderate effect size, with two reviews reporting significant, large effect sizes for quality of life), or showed no difference between groups. There were no negative effects. Adherence to the prescribed intervention: could not be assessed in any review. However, risk of withdrawal/dropout was slightly higher in the exercising group (82.8/1000 participants versus 81/1000 participants), though the group difference was non-significant. Healthcare use/attendance: was not reported in any review. Adverse events, potential harm, and death: only 25% of included studies (across 18 reviews) actively reported adverse events. Based on the available evidence, most adverse events were increased soreness or muscle pain, which reportedly subsided after a few weeks of the intervention. Only one review reported death separately to other adverse events: the intervention was protective against death (based on the available evidence), though did not reach statistical significance.

AUTHORS' CONCLUSIONS

The quality of the evidence examining physical activity and exercise for chronic pain is low. This is largely due to small sample sizes and potentially underpowered studies. A number of studies had adequately long interventions, but planned follow-up was limited to less than one year in all but six reviews.There were some favourable effects in reduction in pain severity and improved physical function, though these were mostly of small-to-moderate effect, and were not consistent across the reviews. There were variable effects for psychological function and quality of life.The available evidence suggests physical activity and exercise is an intervention with few adverse events that may improve pain severity and physical function, and consequent quality of life. However, further research is required and should focus on increasing participant numbers, including participants with a broader spectrum of pain severity, and lengthening both the intervention itself, and the follow-up period.
