N/A Nonspecific chronic neck pain. Intervention 1: Control group (conventional training): The combination of joint position sense and movement sense training (by using laser beam fixed on the head), gaze stability training, eye and head coordination training will be performed in each session and they will be progressed in the next sessions. Eight exercise sessions each lasted 20 minutes is programed. 5 minutes warm up exercises will be performed at the beginning of each session. Intervention 2: Intervention group: (virtual reality training) the computer game is designed to improve cervicocephalic kinesthesia, eye-head coordination, reflexes related to head and neck, eye and vestibular system. The stages of the game are designed easy to difficult sequentially. The duration of each training session and the number of training sessions are the same as conventional group.
