ABSTRACT

PURPOSE:The aim of this study was to determine the effect of device considering Mckenzie type for the subjects with forward head posture (FHP). METHODS:The subjects were 35 patients with FHP(mean age was 23.7 ± 2.8 years; mean height; 172.1 ± 11.7, mean weight; 65.8 ± 13.9, mean NDI(Neck Disability Index; 3.7 ±3.2, mean FHP; 6.7 ± 2.2). We measured the posture with the Body style S-8.0(LU Commerce, South Korea) to evaluate the FHP. We collected the surface EMG(Myosystem 1400, Noraxon, USA) data to quantify changes in normalized activation levels of muscles in SternoCleidoMastoid muscle(SCM), Scalenus Anterior(SA), Trapezius upper fiber(TU) and Splenius Cervicis(SC), during the subjects were instructed to glide their head into a “chin-in” position for a retraction without and with device. RESULTS:The condition with device significantly decreased the %RVC of SA(90.84±40.54), SCM(74.98±43.65) and TU(67.60±47.83) compared to the condition without device(SA;100.39±56.32, SCM;119.03±109.26, Trapezius;80.55±39.27). But the %RVC of capitis(65.87±47.83) with device was increased(70.82±52.78). There was significant difference in the %RVC between SCM and Trapezius muscle in two conditions. CONCLUSION:New device for FHP reduces the EMG activities of the TU, SCM and SA muscle. We have to develop the function of feedback to facilitate the motion in the future.
