Extended Abstract
1. Introduction
Musculoskeletal disorders, including back pain caused by kinesiopathology during daily activities and sports in today's modern society, are one of the most important issues in clinical research. Previous research has linked this issue to lumbar lordosis and the maintenance of back alignment, highlighting its relationship with pain (1). An increase in lumbar lordosis can affect the function of the upper and lower limbs and cause dysfunction in the musculoskeletal system. Additionally, an increase in lumbar lordosis can increase the tilt of the pelvis, and conversely, an increase in anterior tilt can cause the aforementioned abnormality. There is a direct correlation between increased hip tilt and increased hip internal rotation. Moreover, individuals with increased lordosis are more likely to experience knee joint valgus compared to those with normal physical conditions, suggesting that lumbar lordosis may affect lower limb alignment (2).
2. Methods
The present study was a quasi-experimental intervention with a control group. It is quantitative research in terms of data type and applied research in terms of purpose. The statistical population of the purposive research comprised housewives aged 20 to 30 years with a lordosis angle ranging from more than 40 degrees to 56 degrees in Tabriz city. The sample size in both experimental and control groups was calculated using G. Power software, with 46 participants in each group. Both groups underwent measurements before and after the intervention using a tilt meter, flexible ruler, and McGill functional test. The experimental group underwent a 6-week training protocol with muscle functional stimulation, consisting of three sessions per week. The control group received exercises similar to those of the experimental group (post-test). Statistical analysis was performed using independent t-tests and paired t-tests at a significance level of 0.05.
3. Results
In the experimental group compared to the control group in the post-test, there was a significant difference in the components of lumbar lordosis and anterior pelvic tilt (P=0.05). The use of sports rehabilitation protocols with muscle functional stimulation in non-athletic women, as studied in this research, had a significant effect in reducing the duration and popularity of sports and therapeutic rehabilitation courses.
4. Conclusion
One of the most important training methods for improving the pelvic girdle and preventing dysfunction in daily activities is the use of key muscles for active stability in the joints. Previous studies have highlighted the effectiveness and efficiency of exercises with functional flow in this regard. Investigating the mechanism of nerve and muscle stimulation to enhance performance through rehabilitation and sports systems suggests an increase in muscle stimulation simultaneous with involuntary activation of motor units. The significant decrease in lumbar lordosis and anterior pelvic tilt angles in the experimental group compared to the control group underscores the potential benefits of such interventions. Research indicates that physical activities play a crucial role in treating and controlling lumbar lordosis and associated back pain, particularly in youth and adolescence. The use of sports rehabilitation protocols alongside muscles functional stimulation in non-athletes, as studied in this research, can significantly reduce the duration and popularity of sports and therapeutic rehabilitation courses.
