The Effects of Stabilization Exercises Combined With Pelvic Floor Exercise in Women With Nonspecific Low Back Pain: A Randomized Clinical Study.

Objective: The purpose of this study was to investigate the effects of stabilization exercises (SEs) combined with pelvic floor muscle (PFM) exercises versus SE alone on pain intensity, functional disability, and static and dynamic endurance of trunk muscles in women with nonspecific low back pain (LBP). Methods: A total of 48 women with nonspecific LBP (26-45 years) participated in the study. They were randomly allocated into 2 groups. Group A received SEs combined with PFM exercises and physical therapy modalities, and group B received the same intervention without PFM exercises for 6 successive weeks (3 times/wk). Pain intensity, functional disability, and static and dynamic trunk muscle endurance were measured before and after treatment program. Results: After treatment, both groups revealed significant improvements in pain intensity and functional disability scores (P ˂ .05), and significant increases in static and dynamic endurance of trunk flexor and extensor muscles (P ˂ .05). Moreover, there was higher significance in group A compared to group B regarding pain intensity, functional disability scores, and static and dynamic endurance of trunk muscles (P ˂ .05). Conclusion: In this study, the addition of PFM exercise to the SE and physical therapy modalities was more effective in reducing pain intensity, improving functional disability, and increasing the static and dynamic trunk muscle endurance in women with nonspecific LBP compared to SE alone.

Comparison of the effects between low- versus medium-energy radial extracorporeal shock wave therapy on knee osteoarthritis: A randomised controlled trial.

OBJECTIVE: This study aimed to compare the effects between low- versus medium-energy radial extracorporeal shock wave therapy on knee osteoarthritis (KOA). METHOD: Forty-five patients (26 women and 19 men) aged 45-55 years with grade 2 KOA were randomly assigned into the following three groups (all n = 15): Group A received low-energy radial shock wave therapy (2000 shock/session [10 Hz], energy flux density [EFD] 0.02 mJ/mm2) with strengthening exercises once per week for 4 weeks; Group B received medium-energy radial shock wave therapy (2000 shock/session [10 Hz], EFD 0.178 mJ/mm2) with strengthening exercises once per week for 4 weeks; and Group C (control group) received sham shock wave therapy with strengthening exercises once per week for 4 weeks. Severity of pain was determined using the visual analogue scale, and knee physical function was assessed using the Arabic version of the knee injury and osteoarthritis outcome score physical function short form. Knee proprioception was measured before and after the treatment programme using an isokinetic dynamometer. RESULTS: The within-group analysis showed significant differences in severity of pain, knee physical function, and knee proprioception in Groups A and B before and after the treatment programme (p < 0.05). The between-group analysis showed significant differences in all variables after treatment, with more significant differences observed in Group B than in Groups A and C (p < 0.05). CONCLUSION: Low- and medium-energy radial shock wave therapies are effective modalities for the treatment of KOA, with medium-energy radial shock wave therapy being superior to low-energy radial shock wave therapy.
