Avaliação da dor e força muscular de tronco após treinamento em suspensão em mulheres com dor lombar crônica

Abstract

Low back pain (LBP) is one of the main causes of disability worldwide, and physical exercise has been highlighted as a treatment strategy, including suspension training (ST). This study aimed to verify the effects of two ST programs on chronic low back pain (CLBP) and trunk muscle strength in women. This is a planned blinded clinical trial, in which 60 physically active women with CLBP for more than 12 weeks were distributed into three groups: suspension strap training 1 (GTFS1), which progressed in the number of repetitions every four weeks; suspension strap training 2 (GTFS2), which progressed in the difficulty of the exercises; and a control group (CG), which received only postural guidance. Participants were assessed for pain intensity (numerical scale), functional disability (Oswestry Disability Index), and trunk muscle strength and endurance (by dynamometry, resistance tests, and ultrasound). After 12 weeks, significant pain and disability were observed, as well as an increase in muscle strength and endurance in the training groups, especially in GTFS1, although both interventions showed positive results. When comparing the programs, no statistically significant differences were found in most variables. It is concluded that TS promotes pain reduction, improved functional capacity and increased muscle strength in women with CLBP, standing out as a promising therapeutic intervention for this condition.
