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.

Effect of the Mat Pilates method on postural balance and thoracic hyperkyphosis among elderly women: a randomized controlled trial

Abstract Objective: To evaluate the influence of the Mat Pilates method on thoracic hyperkyphosis and postural balance among elderly women. Method: A randomized longitudinal study was performed involving 31 elderly women who were divided into two groups: the Control Group (n=17) and the Pilates Group (n=14). The Pilates Group underwent training while the Control Group attended lectures. Evaluation consisted of specific balance (one-leg right and left) and thoracic kyphosis (computed biophotogrammetry) tests. The subjects were reassessed at the end of eight weeks. Data was analyzed by the Shapiro-Wilk test for normality, and the paired Student's t, the unpaired Student's t, the Wilcoxon, and the Mann-Whitney statistical tests, with a significance level of 5% (p<0.05). Results: The Pilates group maintained balance levels (p>0.05) and had a mean thoracic kyphosis reduction of 6 degrees (p<0.001). There was no significant difference (p>0.005) in any of the variables in the Control Group. Conclusion: The present study found that the Mat Pilates method contributed to a reduction in thoracic kyphosis and the maintenance of balance in the elderly women investigated. REBEC: RBR-6jd8nq
