The purpose of the study was to evaluate the effects of sling exercise program on muscle activity and cervical spine curvature of person with forward head posture. The subjects, 25 students, were divided into two groups. This experiment was intended to examine the muscle activity and cervical spine curvature while the subjects had performed the exercises to do for 2 times/week and 4 weeks. The factors of FHP were measured cranial vertical angle, cranial rotation angle, muscular activity and cervical spine curvature. Cervical spine curvature measured craniovertical, craniocervical, cervicohorizontal and upper cervical angle. Collected data were statistically analyzed by SPSS 10.0. After experiment for 4 weeks period, results were as following: Both group was significant difference of the results according to the CVA. Exercise group are more effective to increase muscle activity (p<.05), but cervical spine curvature was no significant difference. This result, we could find out there was a significant correlation between sling exercise and muscle activity, CVA and CRA.

With the increase of participation in the sport activities, there has been a commensurate rise in the number of sport injuries. A more commonly encountered injured region in the upper-extremity is the wrist. Sport injuries are often characterized as overuse and traumatic. Traumatic injuries include fractures, dislocations, and ligament tears often seen in contact or collision sports. Overuse injuries, represented damages by a level of repetitive microtrauma sufficient to overwhelm the tissues$^{\circ}{\O}$ ability to adapt, include inflammatory conditions such as De Quervain$^{\circ}{\O}s$ disease, extensor carpi ulnaris tendinitis, intersection syndrome. Also included is a traumatic problem such as stress fractures of the hook of the hamate, subluxation of the extensor carpi ulnaris tendon, chronic scapholunate instabilities, and degenerative triangular fibrocartilage tears. This review will focus on both overuse and traumatic injuries of the wrist in the athletes. A significant emphasis will be placed on the evaluation, pearls and pitfalls of conservative and operative treatments.
