Abstract.[Purpose] The purpose of this study was to clarify the effect of cervical stabilizing exercises in the standing position and the supine position on the strength and endurance of deep neck muscles (DNM).[Subjects] Twenty subjects performed cervical stabilizing exercises in the standing position (standing group) and 20 subjects performed cervical stabilizing exercises in the supine position (supine group).[Methods] The subjects did cervical stabilizing exercises in the standing or the supine position three times a week for a total of six weeks. Before and after the experiment, strength and endurance were measured.[Results] Both the standing group and the supine group showed increased strength and endurance after the intervention. However, there was no significant difference in the strength and endurance of the two groups before or after the intervention, or in the pre-post intervention differences.[Conclusion] For cervical strength and endurance improvement, treatment is generally given in the supine position. However, the exercise in the standing position was also effective. Therefore, if there are spatial or equipment limitations, the exercise in the standing position should be taught as an exercise method for the home or office.

This study used radiography measurements and brain wave analysis to examine the correlations between the forward head posture (FHP) of the neck, the range of motion of cervicospinal area, and neurological measures of mental rest, and concentration of college students in their 20s. [Subjects] The subjects of this study were 22 college students (10 males, 12 females) in their 20s. [Methods] The cervical lordosis angle, FHP, and the flexion and extension angles of the cervicospinal area were analyzed from lateral view radiographs, and mental rest and concentration of the brain were measured with a neuro-feedback device. [Results] A higher absolute rotation angle (ARA) was associated with lower anterior weight bearing (AWB) and greater range of flexion and extension motions (RFEM). A higher AWB was associated with a lower RFEM and mental resting state score. Positive correlations were found between increased range of motion of the cervicospinal area and the mental resting state score and between increased RFEM and mental concentration score. [Conclusion] The FHP decreases the range of motion of the cervicospinal area, and this biomechanical problem negatively influences the mental resting state and concentration.

Abstract. [Purpose] This study examined the effects of Gong's mobilization on the cervical lordosis, forward head posture (FHP), cervical range of motion (ROM), and the resting and concentration states of the brain.[Subjects] Forty college students who had problems with cervical posture and ROM were divided into a Gong's mobilization group (n=20) (an experimental group) and a control group (n=20).[Methods] We performed Gong's mobilization on the experimental group three times per week for four weeks and looked at the effects of Gong's mobilization on cervical lordosis, FHP, and cervical ROM. We also examined the effects of Gong's mobilization on the brain's activation levels by analyzing brain waves during the brain's resting and concentrating states using neuro-feedback equipment.[Results] Gong's mobilization increased cervical lordosis, cervical extension ROM (CER), and the ranges of flexion and extension motion (RFEM). It also decreased FHP and enhanced the brain's resting state, rest-α, low rest-β, and high rest-β waves; and during concentration, it increased high β waves.[Conclusion] Gong's mobilization improved FHP and increased the ROM of the cervical spinal area. These improvements in dynamic parts are effective at enhancing the brain's resting state, which indicates that Gong's mobilization may affect the maximization of the brain's steady state and attention and concentration.
