The effects of working hours on nerve conduction test in computer operators

Area of Science:

• Occupational Health
• Neuroscience
• Ergonomics

Background:

• Prolonged computer use is linked to adverse effects on upper extremities.
• Symptoms include pain, paraesthesia, and weakness, with reduced nerve conduction velocities.

Purpose of the Study:

• To investigate if extensive computer operation leads to peripheral neuropathy.
• Utilizing nerve conduction studies to assess upper extremity nerve function.

Main Methods:

• Nerve conduction tests were conducted on 50 computer operators.
• Participants were divided into two groups based on daily computer usage (≥6 hours vs. ≤2 hours).

Main Results:

• Significant differences in physical signs were noted between the groups.
• Nerve conduction velocities for median and ulnar nerves showed significant variations.

Conclusions:

• Long work hours for computer operators correlate with symptoms like pain and weakness.
• Decreased peripheral nerve conduction velocities were observed in high-usage groups.
• Further studies are recommended to assess the predictive value for carpal tunnel syndrome development.
