| Sumario: | Objective. FHP people showed a reduced Semi-Spinalis Capitis muscle (SECM) size in maximal isometric voluntary contraction (MVIC). Also, other studies showed less thickness of this muscle at rest in individuals with pain. So, this muscle must be paramount in subjects with FHP-accompanied neck pain in contraction. Materials and methods. We carried out this observational study with the participation of fifty people with a forward head posture divided into two groups: those with neck pain and those who didn't have neck pain, with a cut-off point of 3 on the VAS. Ultrasonography was used to measure the thickness of the SECM at rest and during maximum isometric contraction in a neutral position. Rest and maximum isometric SECM thickness were normalized using the subject's body weight. For analysis, an independent t-test was used. Results. There was a significant difference in SECM muscle size in MVIC and thickness difference (muscle contraction thickness minus muscle rest thickness) between the two groups (p = 0.043; p = 0.024, respectively). However, there is no significant difference in the resting thickness of SECM between groups (p > 0.05). Conclusions. There is an alteration in SECM muscle size in maximum isometric contraction in FHP subjects with pain, while FHP people without pain didn't show this alteration. Both groups showed a similar alteration in the thickness of the SECM at rest.
