This study aimed to determine how different computer desk heights affect neck and upper body pain, as well as muscle activity, in people with spinal cord injuries. The desk heights were set at 5 cm below the elbow, at the elbow level, and 5 cm above the elbow level. Muscle activity was measured using electromyography (EMG), and subjective discomfort was assessed using the Borg-RPE scale. The study found that the ideal desk height varies depending on the level of spinal cord injury. Individuals with C6 injuries felt less pain with a higher desk, while those with T2-T6 injuries felt less pain with a lower desk.
Computer workstations for individuals with spinal cord injuries should be adjusted to their specific needs and injury level.
Current ergonomic guidelines may not be directly applicable to wheelchair users with spinal cord injuries, highlighting the need for tailored recommendations.
The study suggests that upper trapezius and wrist extensor muscles are particularly affected by computer desk height, implying a focus on these muscles in ergonomic interventions.
