Purpose : This study applied general training (control group) or cranio-cervical flexor training (experimental group) using a pressure biofeedback unit along with general training for 4 weeks to secondary school teachers with moderate to severe neck pain and forward head posture. After that, we tried to compare the effects through differences in neck pain intensity (using numberical rating scale), functional performance (using neck disability index), and cranio-vertebral angle change. Methods : All 50 subjects were randomly assigned to either the "experimental group (n= 25)" or the "control group (n= 25)", and the measurements were evaluated in the same way before the intervention (baseline) and after the intervention (4 weeks). During the intervention period, the subject visited the physiotherapy center and made a reservation three times a week at a fixed time as much as possible, and each training session was thoroughly conducted under the 1:1 guidance of the therapist in charge so that the correct movement and number of times could be performed without compensatory action. Results : As a result of the homogeneity analysis on the general characteristics of the subjects, there were no significant differences between the groups in all variables (p>.05). Compared to the "control group", the "experimental group" showed significant improvement after intervention in all measured variables of neck pain intensity, functional performance, and cranial-vertebral angle (p<.05). Conclusion : For secondary school teachers with forward head accompanied by neck pain, cranio-cervical flexor training using a compression biofeedback unit is an excellent method to show superior pain reduction and functional performance improvement compared to general training alone. In addition, it can be presented as a more effective intervention method that can promote recovery of forward head posture, which is an essential element of the solution.

PURPOSE: The main objective of this study is observing the effects of the functional postural trunk exercise (FPTE) on deep cranio-cervical flexor (CCF) muscle endurance applied on neck pain patients suffering from the acute whiplash-association disorder (WAD). METHODS: The study was tested with 47 patients with neck pain. All patients were equally treated with the ordinary therapy, only experimental group (n=23) was treated with FPTE: assumption of an upright lumbo-pelvic and spinal postural position, adding a neck lengthening manoeuvre in addition. Patients attended physical therapy for 3 times a week, for 4 weeks. Visual analogue scale (VAS) for pain, neck disability index (NDI), range of motion (ROM), were recorded both before and after the intervention. Also muscle activity in the CCF test was employed to analyze the changes between before and after. RESULT: After 4 weeks of training intervention, a remarkable increase in muscle endurance, rotation, extension ROM (p<.05) and decrease in pain and NDI (p<.05) in both groups. Further, the differences between groups were muscle endurance (F=60.350, p<.01), pain, and the left rotation ROM (p<.05). CONCLUSION: From the results, the experimental group had significant the increase in muscle endurance, and the significant decrease in pain. Whilst further research in this category is necessary, these observations suggest that applying exercise in early diagnosis can be of help to treat the neck pain patients suffering from the WAD.

Background: This study was to investigate effects of Correlation Analysis between Cervical-Vertebra Angle and Neck Range of Motion, Muscle Strength, Sternocleidomastoid Thickness of Patients with Forward Head Posture Design: Correlation Analysis. Methods: The subjects of this study were a total of 54 people in the forward head position and their ages were between 30 and 50 years old. The subjects cranio-vertebral angles, neck extension, neck flexion, neck rotation angles, neck flexor strength, neck extensor strength, sternocleidomastoid thickness were evaluated through measuring instruments. The thickness of the sternocleidomastoid muscle was measured using an imaging ultrasound diagnostic device (ultra sound, Versana Premier, GE Medical systems, China). CVA was measured by measuring the side photo of the subject was taken with a camera and evaluated.. neck joint range of motion was measured through digital inclinometer for extension, flexion, and neck rotation. neck muscle strength was measured by measuring the using a digital sthenometer. Data analysis in this study was statistically processed using SPSS version 26.0 (IBM SPSS Inc., USA). Correlation analysis was used and the statistical significance level was set at 0.05. Results: The results neck extension(r= 0.70^**), neck flexion(r= 0.67^**), neck rotation(r= 0.56^**), neck extensor muscle strengt(r= 0.85^**), neck flexor muscle strength(r= 0.66^**), sternocleidomastoid thicknes(r= -0.81^**) It indicates that there is a correlation. Conclusion:These results improve the Cervical-vertebra angle of patients with forward head posture should include a program to improve the thickness of the SCM. In the future, study can be used as an evidentiary material for treatment interventions to improve the Cervical-vertebra angle of patients with forward head posture.
