Introduction:
Non-specific chronic low back pain (CLBP) predominantly affects women aged 40-80 years. Physical exercise is a primary treatment form, with functional training (FT) and dual-task training (DT) emerging as potential modalities due to their distinct characteristics. However, limited information exists regarding the effects of these exercise modalities on CLBP.
Objective:
To compare the FT and DT effects on trunk function and functional fitness in CLBP older women.
Methodology:
This was a randomized clinical trial with two training groups (FT and DT) and CLBP and non-CLBP individuals. We assessed the trunk stability, maximum isometric strength, endurance of trunk muscles, and functional fitness before and after 16 weeks of training RESULTS: We found only time effects for circular stability and instability (p <.001), flexors (p =.006), and extensors endurance (p <.001). For the lateral flexors, there was an average reduction of 17.3 units in lateral flexor endurance in the FT compared to the DT in CLBP individuals. For the strength of the flexor, CLBP individuals exhibited an increase of 69.3 units compared to non-CLBP. For the strength of extensors, CLBP individuals showed a decrease of 75.1 units compared to non-CLBP individuals. We identified a time effect for all functional fitness measures (p <.050) CONCLUSION: FT and DT increase trunk stability, maximum isometric strength, and endurance of trunk muscles, besides the functional fitness of CLBP older women SIGNIFICANCE: Professionals can choose either training type, as there are no differences in the initial 16 weeks of intervention.
