Factors associated with Trochanteric Bursitis and Gluteal Tendinopathy

The hypothesis of this study was that age and weakness of the Gluteus Medius are the main factors associated with trochanteric bursitis and gluteal tendinopathy. The study aims to relate the factors associated with TB and GT, evaluating BMI, age and strength of GMed muscle. The results of this study demonstrated that muscle strength (Kgf) and electrical activity (RMS-%) were similar between the group with trochanteric bursitis and gluteal tendinopathy and the control group; there was no significant difference in relation to BMI. However, in relation to the Trendelenburg test, there was a significant difference between the groups. The age variable presented as a factor associated with trochanteric bursitis and gluteal tendinopathy, being in agreement with the literature. In the present study, there was no significant relationship between BMI and Trochanteric Bursitis and Gluteal Tendinopathy, but the literature presents contradictory evidence. To date, no studies have been found that relate muscle strength (Kgf), MSR (%) and Trendelenburg test as factors associated with TB and GT. In the present study, we chose to evaluate the strength of the GM muscle in lateral decubitus, differently from authors who evaluated in dorsal decubitus and found weakness in the abductor group in gluteal tendinopathy. However, this difference in position is important because it interferes in the production of muscular strength. In this study, the Trendelenburg test was also used to evaluate it as a predictor of the associated factor for trochanteric bursitis and gluteal tendinopathy. The result showed that young adults with Trendelenburg positive had a higher prevalence for TB and GT. Based on the biomechanical analysis of the Balance of Pauwels and the concepts of classical physics on the Vector System and the application of force, we identify the non-correlation between the muscle strength test performed in lateral decubitus and the Trendelenburg test. Considering that one of the main complaints of patients is the difficulty to walk and often with falsehood and lameness, the Trendelenburg test presents as an important predictor of TB and GT. The limitations of the study are mainly due to the cross-sectional design, since it is not known if the weakness of the hip abductors, specifically GMed, is a result or cause of Greater Trochanteric Pain Syndrome, which may be an important factor associated . Another aspect turns to the relation to the time factor of disease development, s
