Effects of pilates training on lumbo-pelvic stability and flexibility

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.

Pilates-based therapeutic exercise for pregnancy-related low back and pelvic pain: A prospective, randomized, controlled trial

Objectives

In this study, we aimed to clarify the impact of a Pilates-based therapeutic exercise on disability, pain, mood, and sleep quality in patients with pregnancy-related lumbopelvic pain (LPP).

Patients and methods

In the single-blinded randomized controlled study conducted between January 2018 and June 2018, 34 pregnant women (mean age: 29.7±6.2 years; range, 18 to 40 years) in the second trimester (week 14-24) with LPP were randomly assigned to a control group and a Pilates group. All patients underwent usual prenatal care. In addition, the selected Pilates exercise was carried out twice a week for 60-min per session for 12 weeks in the Pilates group. The control group was not prescribed an exercise regimen; however, they were not discouraged from exercising. The primary outcome was disability; secondary outcomes were LPP, mood, and sleep quality. Disability [Roland-Morris Disability Questionnaire (RMDQ)], LPP [Visual Analog Scale (VAS)], mood [Hospital Anxiety and Depression Scale, Anxiety (HADS-A) and Depression (HADS-D) subscales], and sleep quality [Pittsburgh Sleep Quality Index (PSQI)] were measured before and after 12 weeks. Adverse effects and adherence were recorded to determine exercise safety and compliance. The intention-to-treat analysis was applied.

Results

The between-group effect sizes were moderate for the RMDQ and VAS scales (d=0.4 and d=0.7, respectively) and small for the HADS-A and HADS-D scales (both d=0.2). The intention-to-treat analysis demonstrated that there was a statistically significant difference in disability, pain, and mood in favor of the Pilates group (p0.05).

Conclusion

Adding Pilates to usual prenatal care should be considered a promising treatment option for pregnancy-related LPP.

Resistance Training Induces Improvements in Range of Motion: A Systematic Review and Meta-Analysis

BACKGROUND

Although it is known that resistance training can be as effective as stretch training to increase joint range of motion, to date no comprehensive meta-analysis has investigated the effects of resistance training on range of motion with all its potential affecting variables.

OBJECTIVE

The objective of this systematic review with meta-analysis was to evaluate the effect of chronic resistance training on range of motion compared either to a control condition or stretch training or to a combination of resistance training and stretch training to stretch training, while assessing moderating variables.

DESIGN

For the main analysis, a random-effect meta-analysis was used and for the subgroup analysis a mixed-effect model was implemented. Whilst subgroup analyses included sex and participants' activity levels, meta-regression included age, frequency, and duration of resistance training.

DATA SOURCES

Following the systematic search in four databases (PubMed, Scopus, SPORTDiscus, and Web of Science) and reference lists, 55 studies were found to be eligible.

ELIGIBILITY CRITERIA

Controlled or randomized controlled trials that separately compared the training effects of resistance training exercises with either a control group, stretching group, or combined stretch and resistance training group on range of motion in healthy participants.

RESULTS

Resistance training increased range of motion (effect size [ES] = 0.73; p < 0.001) with the exception of no significant range of motion improvement with resistance training using only body mass. There were no significant differences between resistance training versus stretch training (ES = 0.08; p = 0.79) or between resistance training and stretch training versus stretch training alone (ES = - 0.001; p = 0.99). Although "trained or active people" increased range of motion (ES = 0.43; p < 0.001) "untrained and sedentary" individuals had significantly (p = 0.005) higher magnitude range of motion changes (ES = 1.042; p < 0.001). There were no detected differences between sex and contraction type. Meta-regression showed no effect of age, training duration, or frequency.

CONCLUSIONS

As resistance training with external loads can improve range of motion, stretching prior to or after resistance training may not be necessary to enhance flexibility.

The effects of clinical pilates training on disease-specific indices, core stability, and balance in patients with ankylosing spondylitis

OBJECTIVE

To assess the effects of clinical Pilates training on disease-specific indices, core stability, and balance in ankylosing spondylitis (AS) patients.

METHODS

AS patients were randomly assigned to either the Pilates group (PG) or control group (CG). The PG participated in Pilates training 3 times a week for 8 weeks. Patients in the CG were instructed to follow a home exercise program for 8 weeks. Assessments were performed before and after the interventions. BASDAI, BASFI, BASMI, and the AS Quality of Life (ASqOL) questionnaire were used were used to evaluate disease activity, functionality spinal mobility and quality of life respectively. Static core endurance was assessed with trunk flexor, extensor endurance, and lateral bridge tests, while dynamic core endurance was assessed using modified sit-up test. Balance was evaluated with bilateral and unilateral stance static postural stability (PS), bilateral stance dynamic PS and limits of stability (LOS) tests using the Biodex Balance System.

RESULTS

Twenty-one patients in the PG and 21 patients in the CG completed the study. PG showed statistically significant improvements in BASDAI, BASFI, BASMI, and ASQoL scores, all core endurance tests, and dynamic PS and LOS results. The CG demonstrated significant improvement only in flexor endurance and LOS results. Post-intervention BASDAI, BASMI, and all core endurance tests were significantly better in the PG than in the CG (p < 0.05).

CONCLUSION

Pilates training has positive effects on disease activity and functional capacity, spinal mobility, core endurance, balance, and quality of life in AS patients.

The Effects of Abdominal Hollowing and Bracing Maneuvers on Trunk Muscle Activity and Pelvic Rotation Angle during Leg Pull Front Pilates Exercise

Pilates methods use mats for trunk muscles stabilization exercises, and leg pull front (LPF) is one of the traditional Pilates mat exercises. Abdominal hollowing (AH) and Abdominal bracing (AB) maneuvers are recommended to stabilize the trunk muscles and prevent unwanted pelvic movement during motion. This study aimed to explore the effects of AH and AB on electromyography (EMG) activity of the trunk muscles and angle of pelvic rotation during LPF. A total of 20 healthy volunteers participated in the study. AH, AB, and without any condition (WC) were randomly performed during LPF exercise. Each was repeated three times for 5 s. The trunk muscle activities were measured using EMG and rotation of pelvis was measured using a Smart KEMA device. The activities of the transversus abdominis/obliquus internus abdominis (TrA/IO) and right obliquus externus abdominis (EO) muscles were highest in LPF-AH compared to the other conditions. Multifidus (MF) activity was significantly greater in LPF-AH and LPF-AB compared to that of without any condition. The pelvic rotation angle was significantly smaller in LPF-AB. Therefore, AH maneuver during LPF for trunk muscle stabilization exercises is suitable for selective activation of the TrA/IO, and AB maneuver during LPF is recommended for the prevention of unwanted pelvic rotation.

The relationship between core muscle endurance and functional movement screen scores in females with lumbar hyperlordosis: a cross-sectional study

Background

Core muscle endurance is essential for proper movement and lower extremity injury prevention. In addition, the Functional Movement Screen (FMS) score is a tool to assess body movement patterns to predict the risk of injury. Although various researches have investigated the relationship between the core muscle endurance and the FMS score, no study has ever assessed the effect of postural deformity on the FMS score. This study investigates the relationship between core muscle endurance and FMS scores in females with lumbar hyperlordosis.

Methods

42 healthy females aged 24.03 ± 4.4 years with hyperlordosis ( > = 45/66 degrees) participated in this study. Core muscle endurance was assessed by the McGill stability test. Correlations were evaluated between the FMS score, McGill test, and lordosis angle using spearman correlation coefficients (p ≤ 0.05).

Results

Most individual FMS scores were not correlated with the McGill test except stability trunk push up. Also, lordosis angle was not correlated with the FMS composite score (r=-0.077; p = 0.631), while it was negatively correlated with the McGill test (r=-0.650; p = 0.000).

Conclusion

The lack of correlation between the FMS score and the McGill test implies that one’s level of core endurance may not influence their functional movement patterns. In contrast, the lumbar lordosis angle might impact one’s core muscle endurance but not their functional movement patterns.

Effect of Pilates Exercises on Standing, Walking, and Balance in Children With Diplegic Cerebral Palsy

Objective

To analyze how Pilates exercises affect standing, walking, and balance in children with diplegic cerebral palsy throughout a 10-week program.

Methods

We included 40 children aged 7–9 years with diplegic cerebral palsy, and randomly allocated them into two groups of the same size: conventional therapy group (group A) and conventional therapy+Pilates group (group B). We administered the same conventional physical therapy program to both groups for 45 minutes, with group B receiving additional Pilates exercises for 45 minutes. Both groups attended the intervention program three times/week for 10 weeks. We used the Growth Motor Function Measure Scale (GMFM-88) to evaluate standing and walking (Dimensions D and E), and the Pediatric Balance Scale to evaluate balance function before and after treatment.

Results

Comparison of the average values of all measured variables before and after therapy showed a statistically significant difference (p<0.05) between the two groups. All measured variables showed a significant difference between groups A and B, in favor of group B (p<0.05).

Conclusion

Pilates exercise in addition to conventional therapy is more effective in improving balance and gross motor function in children with diplegic cerebral palsy than the conventional therapy alone.

Effect of pilates exercises on premenstrual syndrome symptoms: a quasi-experimental study

OBJECTIVES

This study was done to identify the effect of pilates exercises on the symptoms of premenstrual syndrome.

DESIGN

A quasi experimental was conducted on university student with premenstrual syndrome.

METHODS

Population of the study included midwifery students with premenstrual syndrome at Istanbul University Faculty of Health Sciences (N = 286) and 50 of them became the sample (25 in experimental group and 25 in control group). Non-probablistic sampling method was used. While the students in experimental group were asked to practice the pilates exercises for three months, the students in control group were told to maintain their routine habits. At the end of the three months, premenstrual syndrome problem of experimental and control group was diagnosed and the effect of pilates on premenstrual syndrome was evaluated. Premenstrual Syndrome symptoms were evaluated through Premenstrual Syndrome Scale (PMSS). The high score received from PMSS shows that the symptoms are intensive.

RESULTS

It was seen that the students in the experimental and control group were similar in terms of their aspects which were individual, health and could affect premenstrual syndrome (p > 005). A statistical significant difference was not found between total scores and sub-dimension scores of PMSS in experimental and control group (p < 0.05). It was seen that PMSS total score of experimental group was significantly lower than that of control group (p < 0.001). When in-group comparisons were examined, it was identified that PMSS scores of control group did not change at the beginning and end of exercise, but PMSS score of experimental group at the end of exercise was lower than their score received at the beginning of exercise and, the difference was statistically significant to the highest degree (p < 0.001).

CONCLUSION

It was seen that the pilates exercises, which were practiced in this research, decreased the PMS symptoms considerably. In this regard, the pilates exercises have an important role in healing the PMS symptoms.

EVALUATING THE RELATIONSHIP BETWEEN CLINICAL ASSESSMENTS OF APPARENT HAMSTRING TIGHTNESS: A CORRELATIONAL ANALYSIS

BACKGROUND

Hamstring tightness is a common condition typically assessed via the active knee extension (AKE), passive straight leg raise (PSLR), V-sit and reach (VSR), and finger-floor-distance (FFD).

PURPOSE

The purpose of this study was to investigate the relationships between four common clinical tests of apparent hamstring tightness. A secondary purpose was to compare the differences in correlations between sub-groups based on positive test findings.

STUDY DESIGN

Descriptive, correlational laboratory design.

METHODS

Recreationally active individuals (N = 81; 23.7 ± 5.9 years) performed the AKE, PSLR, VSR, and FFD in a randomized order, and subsequent correlational analyses were conducted.

RESULTS

Strong correlations were identified between the VSR and FFD (r = -.798, r² = .637, p < .001); moderate correlations were demonstrated between the PSLR and FFD (r = -.565, r² = .319, p < .001) and PSLR and VSR (r = .536, r² = .287, p < .001). Low correlations were found between the PSLR and AKE (r = -.284, r² = .081, p = 0.01), AKE and VSR (r = -.297, r² = .088, p = .007), and AKE and FFD (r = .263, r² = .069, p = .018). If one assessment was identified in a subject as dysfunctional, all relationships were affected, regardless of which assessment was dysfunctional.

CONCLUSIONS

The AKE, one of the most common measures for apparent hamstring tightness, has low correlations with the other assessments. Based on the findings of this study, it is possible that not all assessments of AHT are measuring the same phenomena, with each involving different factors of perceived hamstring length.

Pilates training improves 5-km run performance by changing metabolic cost and muscle activity in trained runners

Purpose

Strength training improves distance running economy and performance. This finding is based predominantly on maximal and explosive strength programmes applied to locomotor muscles, particularly on the lower limbs. It is not certain whether a minimization of metabolic cost (C_met) and an improvement in running performance is feasible with strength training of the postural and trunk muscles.

Methods

Using kinematic, neuromuscular and metabolic measurements of running at two different speeds before and after a 12-week Pilates training programme, we tested the hypothesis that core training might improve the running C_met and performance of trained runners. Thirty-two individuals were randomly assigned to the control group (CG, n = 16) or the Pilates group (PG, n = 16).

Results

Confirming our hypothesis, a significant improvement (p<0.05) was observed for running performance in the PG (pre: 25.65±0.4 min; post: 23.23±0.4 min) compared to the CG (pre: 25.33±0.58 min; post: 24.61±0.52 min). Similarly, the PG (4.33±0.07 J.kg^-1.m^-1) had better responses than the CG (4.71±0.11 J.kg^-1.m^-1) during post-training for C_met. These findings were accompanied by decreased electromyographic activity of the postural muscles at submaximal running intensities in the PG.

Conclusions

Overall, these results provide a rationale for selecting strength training strategies that target adaptations on specific postural and locomotor muscles for trained distance runners.

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.

Respiratory characteristics of individuals with non-specific low back pain: A cross-sectional study

Non-specific low back pain (NS-LBP) is known to cause respiratory dysfunction. In this study, we investigated alterations in breathing, respiratory strength and endurance, core stability, diaphragm mobility, and chest expansion among patients with NS-LBP and healthy individuals. The specific aim of the study was to correlate between respiratory function and other variables among NS-LBP patients. Thirty four patients with NS-LBP were matched with 34 healthy participants before undergoing total faulty breathing scale, spirometer, respiratory pressure meter, chest expansion, ultrasound, and pressure biofeedback measurements. There were signs of faulty breathing in the NS-LBP patients when compared to the healthy participants. Diaphragmatic mobility and respiratory muscle endurance were lower in the NS-LBP group. Chest expansion exhibited a significant decrease at the level of the fourth intercostal space in the NS-LBP group, but respiratory muscle strength and core stability were not significant between the two groups. Positive correlations were found to be fairly significant regarding respiratory muscle strength. The findings of this study indicated altered respiratory characteristics in the NS-LBP patients, and suggested that they would improve through respiratory exercises.

Comparação da satisfação, motivação, flexibilidade e dor muscular tardia entre método Pilates moderno e método Pilates instável

RESUMO O objetivo deste estudo foi comparar a satisfação e motivação para a prática de exercício físico, flexibilidade e dor muscular tardia (DMT) em participantes saudáveis após exercícios de duas modalidades do método Pilates. Para isso, cinquenta participantes saudáveis realizaram uma sessão de exercícios do Pilates moderno e outra do Pilates instável. Foram avaliados os desfechos satisfação e motivação após as sessões, flexibilidade posterior do tronco e membros inferiores (banco de Wells) antes e após cada sessão, e DMT 24, 48 e 72 horas após cada sessão (Escala Numérica de Dor). Os resultados mostraram que não houve diferença estatisticamente significante entre as duas modalidades do Pilates para satisfação e motivação, flexibilidade e DMT 72 horas após a sessão (p>0,05). Para a DMT foi observada diferença estatisticamente significante entre as duas modalidades 24 horas (diferença entre as médias: -0,7; IC a 95%: -1,5 a 0,0) e 48 horas (diferença entre as médias: -0,8; IC a 95%: -1,4 a -0,2) após a sessão, com maior dor no Pilates instável. Como conclusão, as duas modalidades do Pilates apresentaram o mesmo nível de satisfação e motivação e ganho similar de flexibilidade. No entanto, o Pilates instável causou mais DMT após 24 e 48 horas, mas essa diferença não foi clinicamente relevante.

Lumbopelvic Core Stabilization Exercise and Pain Modulation Among Individuals with Chronic Nonspecific Low Back Pain

BACKGROUND

Lumbopelvic stabilization training (LPST) may provide therapeutic benefits on pain modulation in chronic nonspecific low back pain conditions. This study aimed to examine the effects of LPST on pain threshold and pain intensity in comparison with the passive automated cycling intervention and control intervention among patients with chronic nonspecific low back pain.

METHODS

A within-subject, repeated-measures, crossover randomized controlled design was conducted among 25 participants (7 males and 18 females) with chronic nonspecific low back pain. All the participants received 3 different types of experimental interventions, which included LPST, the passive automated cycling intervention, and the control intervention randomly, with 48 hours between the sessions. The pressure pain threshold (PPT), hot-cold pain threshold, and pain intensity were estimated before and after the interventions.

RESULTS

Repeated-measures analysis of variance showed that LPST provided therapeutic effects as it improved the PPT beyond the placebo and control interventions (P < 0.01). The pain intensity under the LPST condition was significantly better than that under the passive automated cycling intervention and controlled intervention (P < 0.001). Heat pain threshold under the LPST condition also showed a significant trend of improvement beyond the control (P < 0.05), but no significant effects on cold pain threshold were evident.

CONCLUSIONS

Lumbopelvic stabilization training may provide therapeutic effects by inducing pain modulation through an improvement in the pain threshold and reduction in pain intensity. LPST may be considered as part of the management programs for treatment of chronic low back pain.

The effects of Pilates breathing trainings on trunk muscle activation in healthy female subjects: a prospective study

[Purpose] To investigate the effects of Pilates breathing on trunk muscle activation. [Subjects and Methods] Twenty-eight healthy female adults were selected for this study. Participants’ trunk muscle activations were measured while they performed curl-ups, chest-head lifts, and lifting tasks. Pilates breathing trainings were performed for 60 minutes per each session, 3 times per week for 2 weeks. Post-training muscle activations were measured by the same methods used for the pre-training muscle activations. [Results] All trunk muscles measured in this study had increased activities after Pilates breathing trainings. All activities of the transversus abdominis/internal abdominal oblique, and multifidus significantly increased. [Conclusion] Pilates breathing increased activities of the trunk stabilizer muscles. Activation of the trunk muscle indicates that practicing Pilates breathing while performing lifting tasks will reduce the risk of trunk injuries.

Effects of modified Pilates on variability of inter-joint coordination during walking in the elderly

[Purpose] This study aimed to examine the effects of an 8-week modified Pilates program on the variability of inter-joint coordination in the elderly during walking. [Subjects and Methods] Twenty elderly participants with no recent history of orthopedic abnormalities (age, 67.9 ± 2.7 years; height, 163.7 ± 8.9 cm; weight, 67.1 ± 11.6 kg) were recruited for this study and randomly allocated to a modified Pilates exercise group or a control group. Three-dimensional motion analysis was performed on both groups to evaluate the effects of the Pilates exercise. [Results] There was no significant difference in the joint variability of the ankle, knee, and hip joints between the groups, both before training and after training. However, there was a significant increase in the hip-knee deviation phase value in the exercise group after the program was completed, and this increase was also significant when compared with that in the control group. [Conclusion] This study has demonstrated that an 8-week modified Pilates exercise program can have a positive impact on the gait of elderly participants, potentially by enhancing neuromuscular adjustment, which may have positive implications for reducing their fall risk.

Effects of 8 weeks of mat-based Pilates exercise on gait in chronic stroke patients

[Purpose] The purpose of this study was to investigate the effects of an 8-week program of Pilates exercise on gait in chronic hemiplegia patients and to determine whether or not it can be used for rehabilitation in postsrtoke patients. [Subjects and Methods] Twenty individuals with unilateral chronic hemiparetic stroke (age, 66.1 ± 4.4 yrs; height, 162.3 ± 8.3 cm; weight, 67.4 ± 12.3 kg) participated in this study and were randomly allocated equally to either a Pilates exercise group or a control group. To identify the effects of Pilates exercise, a 3-D motion analysis with 8 infrared cameras was performed. [Results] For the gait parameters, improvements were found in the Pilates exercise group for all variables, and statistical significance was observed for stride length, gait velocity, knee range of motion and hip range of motion. For the asymmetry indexes, insignificant improvements were found for all variables in the Pilates exercise group. [Conclusion] In conclusion, an 8-week program of Pilates exercise had a positive influence on improving the gait ability of poststroke patients, and the intervention could be applied to poststroke patients with various levels of physical disability by adjusting the intensity of training.

The Pilates method in the rehabilitation of musculoskeletal disorders: a systematic review

Abstract Introduction: Joseph Pilates created an authentic method of physical and mental conditioning, which he called Contrology and defined as the complete coordination of body, mind and spirit. Recent studies indicate that the Pilates Method is a useful tool in rehabilitation can improve overall health, sports performance and help in the prevention and attenuation of injuries and disorders of the musculoskeletal system. Musculoskeletal disorders are prevalent and costly conditions that develop gradually, presenting a chronic course and often remain untreated. Objective: This study aimed to identify the effects of the Pilates Method in the rehabilitation of musculoskeletal disorders through a systematic review. Methods: An active search was performed in the PubMed, PEDro, Scielo and Bireme databases. A total of 24 studies were pre-selected and their methodological quality was evaluated based on the PEDro scale. Of these, 14 fulfilled the selection criteria. Results: The studies analyzed indicate that Pilates can be effective both for the treatment of conditions such as scoliosis, back pain, ankylosing spondylitis and breast cancer, and for preventing injuries in adults, elderly people and athletes. Conclusion: The high methodological variability requires that these studies be viewed with caution. It indicates the need for the performance of new studies with high methodological quality and standardization of evaluation instruments.

Effects of a 16-week Pilates exercises training program for isometric trunk extension and flexion strength

OBJECTIVE

To evaluate the effects of Pilates exercises designed to improve isometric trunk extension and flexion strength of muscles in women with chronic low back pain (cLBP).

PARTICIPANTS

Female volunteers with cLBP were divided into an experimental group (EG; n = 27) and a control group (CG; n = 27).

INTERVENTION

Pilates exercises were performed twice per week by the EG; the duration of each session was 60 min. The program lasted for 16 weeks; thus patients underwent a total of 32 exercise sessions.

RESULTS

The maximum isometric waist bending strength of the EG had improved significantly (p = 0.001) after 16 weeks of the Pilates program. The results of trunk flexion muscle endurance tests significantly depended on the trunk extension muscle endurance before the intervention, and at 1 month (r = 0.723, p < 0.001) and 2 months (r = 0.779, p < 0.001) after the Pilates exercise program. At the end of the 16-week exercise program, cLBP intensity decreased by 2.01 ± 0.8 (p < 0.05) in the EG, and this reduction persisted for 1 month after completion of the program.

CONCLUSIONS

At 1 and 2 months after cessation of the Pilates exercise program the pain intensified and the functional state deteriorated much faster than the maximum trunk muscle strength. Therefore, it can be concluded that, to decrease pain and improve functional condition, regular exercise (and not only improved strength and endurance) is required. We established that, although the 16-week lumbar stabilization exercise program increased isometric trunk extension and flexion strength and this increase in strength persisted for 2 months, decreased LBP and improved functional condition endured for only 1 month.

Pilates for low back pain

BACKGROUND

Non-specific low back pain is a major health problem worldwide. Interventions based on exercises have been the most commonly used treatments for patients with this condition. Over the past few years, the Pilates method has been one of the most popular exercise programmes used in clinical practice.

OBJECTIVES

To determine the effects of the Pilates method for patients with non-specific acute, subacute or chronic low back pain.

SEARCH METHODS

We conducted the searches in CENTRAL, MEDLINE, EMBASE, CINAHL, PEDro and SPORTDiscus from the date of their inception to March 2014. We updated the search in June 2015 but these results have not yet been incorporated. We also searched the reference lists of eligible papers as well as six trial registry websites. We placed no limitations on language or date of publication.

SELECTION CRITERIA

We only included randomised controlled trials that examined the effectiveness of Pilates intervention in adults with acute, subacute or chronic non-specific low back pain. The primary outcomes considered were pain, disability, global impression of recovery and quality of life.

DATA COLLECTION AND ANALYSIS

Two independent raters performed the assessment of risk of bias in the included studies using the 'Risk of bias' assessment tool recommended by The Cochrane Collaboration. We also assessed clinical relevance by scoring five questions related to this domain as 'yes', 'no' or 'unclear'. We evaluated the overall quality of evidence using the GRADE approach and for effect sizes we used three levels: small (mean difference (MD) < 10% of the scale), medium (MD 10% to 20% of the scale) or large (MD > 20% of the scale). We converted outcome measures to a common 0 to 100 scale when different scales were used.

MAIN RESULTS

The search retrieved 126 trials; 10 fulfilled the inclusion criteria and we included them in the review (a total sample of 510 participants). Seven studies were considered to have low risk of bias, and three were considered as high risk of bias.A total of six trials compared Pilates to minimal intervention. There is low quality evidence that Pilates reduces pain compared with minimal intervention, with a medium effect size at short-term follow-up (less than three months after randomisation) (MD -14.05, 95% confidence interval (CI) -18.91 to -9.19). For intermediate-term follow-up (at least three months but less than 12 months after randomisation), two trials provided moderate quality evidence that Pilates reduces pain compared to minimal intervention, with a medium effect size (MD -10.54, 95% CI -18.46 to -2.62). Based on five trials, there is low quality evidence that Pilates improves disability compared with minimal intervention, with a small effect size at short-term follow-up (MD -7.95, 95% CI -13.23 to -2.67), and moderate quality evidence for an intermediate-term effect with a medium effect size (MD -11.17, 95% CI -18.41 to -3.92). Based on one trial and low quality evidence, a significant short-term effect with a small effect size was reported for function (MD 1.10, 95% CI 0.23 to 1.97) and global impression of recovery (MD 1.50, 95% CI 0.70 to 2.30), but not at intermediate-term follow-up for either outcome.Four trials compared Pilates to other exercises. For the outcome pain, we presented the results as a narrative synthesis due to the high level of heterogeneity. At short-term follow-up, based on low quality evidence, two trials demonstrated a significant effect in favour of Pilates and one trial did not find a significant difference. At intermediate-term follow-up, based on low quality evidence, one trial reported a significant effect in favour of Pilates, and one trial reported a non-significant difference for this comparison. For disability, there is moderate quality evidence that there is no significant difference between Pilates and other exercise either in the short term (MD -3.29, 95% CI -6.82 to 0.24) or in the intermediate term (MD -0.91, 95% CI -5.02 to 3.20) based on two studies for each comparison. Based on low quality evidence and one trial, there was no significant difference in function between Pilates and other exercises at short-term follow-up (MD 0.10, 95% CI -2.44 to 2.64), but there was a significant effect in favour of other exercises for intermediate-term function, with a small effect size (MD -3.60, 95% CI -7.00 to -0.20). Global impression of recovery was not assessed in this comparison and none of the trials included quality of life outcomes. Two trials assessed adverse events in this review, one did not find any adverse events, and another reported minor events.

AUTHORS' CONCLUSIONS

We did not find any high quality evidence for any of the treatment comparisons, outcomes or follow-up periods investigated. However, there is low to moderate quality evidence that Pilates is more effective than minimal intervention for pain and disability. When Pilates was compared with other exercises we found a small effect for function at intermediate-term follow-up. Thus, while there is some evidence for the effectiveness of Pilates for low back pain, there is no conclusive evidence that it is superior to other forms of exercises. The decision to use Pilates for low back pain may be based on the patient's or care provider's preferences, and costs.

Efeitos do método pilates no torque isocinético dos extensores e flexores do joelho: estudo piloto

INTRODUÇÃO: apesar da popularização do método Pilates como forma de exercício físico, os estudos com a técnica ainda não têm explorado os seus efeitos sobre o torque isocinético dos músculos extensores e flexores do joelho.OBJETIVO: verificar os efeitos do método Pilates no torque isocinético dos extensores e flexores do joelho em mulheres jovens.MÉTODOS: 10 voluntárias foram submetidas à avaliação isocinética (60°/s e 300°/s) dos extensores e flexores do joelho, do membro inferior dominante, pré e pós-intervenção com o método Pilates, considerando-se o pico de torque (PT) e o trabalho total (TT). Oito intervenções foram realizadas ao longo de quatro semanas, constando de 28 exercícios de alongamento e fortalecimento para os principais grupos musculares. A análise estatística, utilizando os testes tde Student ou Wilcoxonpara amostras dependentes, foi utilizada (p<0,05).RESULTADOS: os resultados mostraram melhora significativa para a maioria das variáveis observadas, tanto na extensão do joelho (TT 60°/s - 8,98%, p = 0,0166; PT 300°/s - 11,80%, p = 0,0077; TT 300°/s - 19,68%, p = 0,0051), quanto na flexão (PT 60°/s - 11,44%, p = 0,0171; TT 60°/s - 11,55%, p = 0,0395; TT 300°/s - 12,86%, p = 0,0145), com exceção para duas variáveis, uma referente ao movimento de extensão do joelho (PT 60°/s - 3,04%, p = 0,4413) e outra ao movimento de flexão (PT 300°/s - 2,30%, p = 0,3873).CONCLUSÃO: foi possível verificar que oito sessões de Pilates, realizadas ao longo de quatro semanas, proporcionaram melhora significativa do torque isocinético dos músculos extensores e flexores do joelho em mulheres jovens, em relação ao PT e TT (60°/s e 300°/s) para a maioria das variáveis analisadas.

The effects of a single bout pilates exercise on mRNA expression of bone metabolic cytokines in osteopenia women

[Purpose]

The purpose of this study was to examine the effect of a single bout pilates exercise on mRNA expression of bone metabolic cytokines in elderly osteopenia women.

[Methods]

We selected 11 people of elderly osteopenia women and loaded a single bout pilates exercise about RPE 10-14 level. The blood samples were collected before, immediately after and 60 minute after pilates exercise, then examined calcium metabolic markers in serum and extracted peripheral blood mononuclear cell (PBMC) from whole blood and confirmed mRNA expression of bone metabolic cytokines from PBMC. To clarify the changes during exercise, we designed repeated measure ANOVA as the control group to perform blood sampling without exercise.

[Results]

As a result, serum P showed significant interaction effect between group and time (p<.001), the pilates exercise group decreased about 9% at immediately after exercise and 13% during recovery after exercise (p<.05), while the control group showed a tendency to increase. Serum CK also showed a significant interaction between group and time (p<.05), the pilates group significantly increased at immediately after exercise and during recovery after exercise (p<.05) but the control group didn’t have changes. TNF-α and IL-6 mRNA expression in PBMC was significantly increased in the pilates group (p<.01, p<.05), although INF-γ mRNA expression didn’t show statistically significant difference, it tended to increase in the pilates group (NS).

[Conclusion]

These results suggested that a single bout pilates exercise of elderly osteopenia women cause hypophosphatemia with temporary muscle damage, and it leading high turnover bone metabolic state with to activate both of bone formation and bone resorption.

Expanding Panjabi's stability model to express movement: a theoretical model

Novel theoretical models of movement have historically inspired the creation of new methods for the application of human movement. The landmark theoretical model of spinal stability by Panjabi in 1992 led to the creation of an exercise approach to spinal stability. This approach however was later challenged, most significantly due to a lack of favourable clinical effect. The concepts explored in this paper address and consider the deficiencies of Panjabi's model then propose an evolution and expansion from a special model of stability to a general one of movement. It is proposed that two body-wide symbiotic elements are present within all movement systems, stability and mobility. The justification for this is derived from the observable clinical environment. It is clinically recognised that these two elements are present and identifiable throughout the body in different joints and muscles, and the neural conduction system. In order to generalise the Panjabi model of stability to include and illustrate movement, a matching parallel mobility system with the same subsystems was conceptually created. In this expanded theoretical model, the new mobility system is placed beside the existing stability system and subsystems. The ability of both stability and mobility systems to work in harmony will subsequently determine the quality of movement. Conversely, malfunction of either system, or their subsystems, will deleteriously affect all other subsystems and consequently overall movement quality. For this reason, in the rehabilitation exercise environment, focus should be placed on the simultaneous involvement of both the stability and mobility systems. It is suggested that the individual's relevant functional harmonious movements should be challenged at the highest possible level without pain or discomfort. It is anticipated that this conceptual expansion of the theoretical model of stability to one with the symbiotic inclusion of mobility, will provide new understandings on human movement. The use of this model may provide a universal system for body movement analysis and understanding musculoskeletal disorders. In turn, this may lead to a simple categorisation system alluding to the functional face-value of a wide range of commonly used passive, active or combined musculoskeletal interventions. Further research is required to investigate the mechanisms that enable or interfere with harmonious body movements. Such work may then potentially lead to new and evolved evidence based interventions.

Intrarater reliability of pain intensity, tissue blood flow, thermal pain threshold, pressure pain threshold and lumbo-pelvic stability tests in subjects with low back pain

Purpose

This preliminary study aimed to determine the intrarater reliability of the quantitative tests for the study of non-specific low back pain.

Methods

Test-retest reliability of the measurements of ratio data was determined by an intraclass correlation coefficient (ICC), standard error of measurements (SEMs), coefficient of variation (CV), and one-way repeated measures ANOVA using the values collected from 13 young individuals (25.8 ± 6.2 years) with chronic non-specific low back pain on two occasions separated by 2 days. Percent agreement of the ordinal data was also determined by Cohen's Kappa statistics (kappa). The measures consisted of tissue blood flow (BF), average pain visual analog scales (VAS), pressure pain threshold (PPT), cold pain threshold (CPT), heat pain threshold (HPT) and lumbo-pelvic stability test (LPST). An acceptable reliability was determined as the ICC values of greater than 0.85, SEMs less than 5%, CV less than 15%, the kappa scores of greater than 80% and no evidence of systematic error (ANOVA, P>0.05).

Results

ICC of all measures in the lumbo-sacral area were greater than 0.87. The kappa was also greater than 83%. Most measures demonstrated a minimal error of measurements and less potential of systemic error in nature. Only the SEMs and the CV of the CPT exceeded the acceptable level.

Conclusions

It is concluded that most of the quantitative measurements are reliable for the study of non-specific low back pain, however the CPT should be applied with care as it has a great variation among individuals and potential of measurement error.

Hip dysplasia and the performing arts: is there a correlation?

Dancers frequently present with hip pain. The etiology of this pathology has not been clearly identified from an anatomical perspective. Structural variations including hip dysplasia and dynamic variables from the foot to the pelvis will be discussed. Understanding the etiology as a structural entity, neuromuscular entity or a combination of the two, allows for a successful rehabilitative process and a successful return to dance. This article describes the possible correlation between hip dysplasia and hip pain in the dancer, the relationship of dance postures to the kinematic chain and outlines possible treatment strategies for management.
