Background: Compared with healthy people, patients with chronic tension-type headache (CTTH) are likely to have forward head postures (FHP) and a higher number of active trigger points (aTrP) on the suboccipital muscle.
Objective: This study aims to verify how the suboccipital muscle inhibition (SMI) on aTrPs and the FHP correction exercise can effectively reduce symptoms of the CTTH patients.
Method: The subjects of this study were 45 individuals with CTTH, divided into three groups of 15 patients each: a) the SMI group using the myofascial release technique; b) the SMIEx group subject to both the SMI therapy and FHP correction exercises; and c) the control group. Group A and B were given the relevant interventions twice a week for four consecutive weeks, and went through the headache impact test (HIT-6) and examinations on the pressure pain threshold (PPT) of the headache areas, the type and number of myofascial trigger points (TrP), the soft tissue PPT, and the posture before and after the intervention.
Results: There was a significant improvement in the HIT-6, the headache PPT, the soft tissue PPT, the TrP, and the posture in Group A and B patients to whom the SMI technique and SMIEx interventions were applied. The biggest reduction and increase in the HIT-6 and the headache PPT respectively were seen in the SMIEx group.
Conclusion: According to this study, the SMIEx can be an effective intervention for patients with CTTH.
