The NDI is valid, reliable and responsive to chronic musculoskeletal dysfunction (MacDermid et al., 2009) and has a moderate construct validity and reliability of 0.89 in UQMP populations (Young et al, 2009).
Visual analysis of data took place; descriptive statistics (means and standard deviations [SD]) and graphic representation of the six outcomes (intensity and frequency of both UQMP and muscle tension, functional disability and productivity) were applied to each participant per phase.
No work absenteeism or activity impairment associated with UQMP was reported by either participant throughout the study.
The dependant variables were all self-reported and included subjective chronic UQMP and muscle tension, functional neck disability and perceived impairment of computer work due to the UQ musculoskeletal dysfunction.
The study findings illustrate that both participants' UQMP, muscle tension and disability reduced in the short term and at follow-up assessment.
There is evidence for an association between sitting, postural angles and UQMP (Brink and Louw, 2013).
Strom et al, (2012) identified peripheral sensitisation as a dominant pain mechanism in computer workers with UQMP. Self-reported pain does not relate to possible pain mechanisms, but theoretically, reduced peripheral sensitisation may explain study findings.
