The Effect of Motor Control Ergonomic Program on Neck Pain Worker during Computer Use

Computer use required to maintain a long period of static postures, as well as shoulder and neck muscles sustained contraction. There is a high relevancy between neck pain and computer use. Science the computer use has become an activity in daily work for an increasing number of individuals, this problem deserves to be thought highly. Previous studies have often focused on the effect of changing parts of the VDT workstation. However, there are multi-intrinsic factors between neck pain patient and asymptomatic subject (neuromuscular physiologic status, mental workload, muscle recruitment pattern, kinematics pattern). Therefore, the neck pain worker need an innovative motor control (muscle recruitment pattern & kinematics pattern) ergonomic program in computer use, differ from the asymptomatic subject. These innovative ideas that will effectively reduce the discomfort degree on the neck pain worker. This project defines the neuromuscular physiologic status by using the Neck Disability Index. Recruit neck pain worker as experimental group and asymptomatic subject as control group, investigate the interaction within the mental workload, working posture (kinematics pattern), muscle recruitment pattern and discomfort (assessed by the Visual Analog Scale). The purpose of the first year is to investigate the interaction effect between neck pain and the working posture from 40 subjects. The purpose of the second year is to proof the effect that reduces neck discomfort degree of the motor control ergonomic program form 30 subjects. The expected results of this two-year project are: (1) Investigate the interaction effect within four factors (neuromuscular physiologic status, mental workload, muscle recruitment pattern, kinematics pattern). (2) Investigate the relation between neck pain and four factors. (3) Proposed the motor control ergonomic program for neck pain worker. (4) To proof the effect that reduces neck discomfort degree of the motor control ergonomic program. (5) Proposal the concept and apply method of the motor control ergonomic program.
