Dry Needling and Lateral Hip Pain (GTPS)

Introduction: Greater Trochanter Pain Syndrome (GTPS) includes a number of disorders involving the lateral hip region, including bursitis, gluteal lacerations, and trigger points in the contractile tissue crossing the hip. As an alternative resource for pain relief, dry needling, known as Dry Needling (DN) is a technique that has been shown to be effective in the treatment of soft tissue injuries and neuromyofascial pain, with positive effects on musculoskeletal conditions. Objective: to compare the administration of ND and laser therapy on the effectiveness of reducing lateral hip pain and improving function in women with GTPS. Materials and methods: The sample will consist of 30 women, aged between 35 and 60, randomized into 2 groups: GND group (n=15) and GLT group (n=15). Participants will complete the sample characterization questionnaire, the numerical pain scale and the VISA Tendinopathy Questionnaire for Greater Trochanteric Pain Syndrome (VISA-G). Subsequently, they will be submitted to evaluation through functional tests sit and stand 30 seconds, Timed up and go test. After the evaluation, they will be submitted to the treatment. The GDN will receive treatment using the technique by a physiotherapist with specific training in NP. The application will be through the deep technique, in the regions of trigger points of muscles of the posterolateral region of the hip with duration of application from 30 to 60 seconds per point, 8 points of application will be standardized, in the region of muscles of the posterolateral region. hip side. The GLT will receive the Laser application by a physiotherapist specialized in traumato-orthopedics. The equipment will be the Infrared Laser (wavelength 904 nm), by punctual technique. Eight application points will be standardized in the muscles region of the posterolateral region of the hip.

If a patient is using an anti-inflammatory, guided by the orthopedist, or a physiotherapy treatment protocol, start only 10 days after the end of the same. As participants, they will be instructed to avoid activities that cause pain during the research period. All others selected until the final evaluation will be discouraged. For all groups, the use of analytical medication prescribed by the orthopedist will be allowed, when requested. As the participants will be asked each session about the use of their analog, the data and the dosage that will occur during the study period will be noted. If necessary, how researchers will contact the orthopedist for information and guidance. If a participant needs to use anti-inflammatory medication during a survey, they will be excluded. The analyzes will be carried out by a blind researcher regarding the allocation of the subjects in each group. Participants who have missing data and those who do not attend all treatment sessions will be included in the analysis.

To establish the results, the following variables will be considered:

* Pain intensity: VAS
* Quality of life: VISA-G questionnaire
* Functional assessment: Soon after, the following functional tests will be performed: 30-second Sit to Stand Test (SL30) and the Timed Up and Go Test (TUG).

The Shapiro-Wilk test will be applied to determine the normality of the sample. Student's t test will be used to compare age, weight, height, body mass index (BMI), and the presence of pain when lying on the hip between groups. The two-way ANOVA test (with Bonferroni post-test) will be used to compare the intra-group and intergroup results, if the data are normal, and will be described as mean and standard deviation. Cohen's D test will be performed to calculate the effect size. Linear correlation between variables will be investigated by Pearson's (or Spearman's) correlation test. If there is a linear correlation between any of the potentially confounding variables, analysis of covariance will be performed using the ANCOVA test. Other necessary analyzes may still be included. The level of statistical significance will be set at p ≤ 0.
