Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the experimental group, a one-time therapy of the temporomandibular joints will be used. The therapy will consist of soft tissue mobilization techniques inside and outside the temporomandibular joints. External techniques will include 1-minute compression on the trigger points, positional release and myofascial release within the temporal muscle and masseter muscle. Internal techniques will include coppression and relaxation of the pterygoid muscle and masseter muscle. The therapy will be performed by physiotherapist in the supine position of patient and will last approximately 15 minutes. The measurements will be performed before and after the therapy.

Rehabilitation
Comparator / control treatment
The second group will be the no-intervention control group. In this group, the measurements will be carried out also twice with a 15-minute break between measurements, without the intervention applied. During the 15-minute break, patients will be laying in the supine position.
Control group
Active

Outcomes
Primary outcome [1] 334672 0
Evaluation of the bioelectrical activity at rest and during volitional contractions of the pelvic floor muscles, using surface electromyography. Evaluation of the following muscles will be performed: pelvic floor muscles, masseter muscles, sternocleidomastoid muscles, trapezius dorsi descending and ascending parts. The results will be analyzed together, indicating muscle activity and the relationships between them.

Efficacy
Statistical methods / analysis
Statistical analysis will be performed using the STATISTICA 12.0 Pl software. The Shapiro–Wilk test will be conducted to assess data for normality. To determine the significance of differences analysis of variance will be performed. Post-hoc analysis will performed using the post-hoc test. Using the paired t-test for power analysis of exercise, it was determined that at least 17 subjects from each group were required to obtain a power of 0.8 at a two-sided level of 0.05 with the effect size of d = 0.8.

Summary
Brief summary
The pelvic floor muscles play an important role in the proper functioning of the pelvic and abdominal organs. The pelvic floor muscles are structurally connected to other areas of the body, forming part of the deep anterior line which is one of myofascial chains.. Due to its course, this line connects the pelvic floor muscles with two distant areas - the sole of the foot and the temporomandibular joint. Functional and structural connections between these elements of the musculoskeletal system allow to assume that the applied therapy may cause beneficial effects not only in the area of temporomandibular joints, but also in the cervical section, pelvic floor muscles and feet. The aim of the study is to evaluate a single therapy within the temporomandibular joints on the activity of the pelvic floor muscles. In addition, taking into account the connections within the anterior myofascial band, the effect of therapy on the balance and load distribution of the feet will be assessed.
