Abstract: At-work exercises are commonly recommended for computer operators.
This randomized control trial assessed adherence, pain and satisfaction after 4
weeks of at-work exercise. Subjects (n=72) were randomized into 3 groups:
resistance exercise, stretching, and control. Outcomes included a satisfaction
survey, a visual analogue pain scale (VAS), a pain drawing, and the Neck
Disability Index (NDI). The VAS, the drawing, and NDI were analyzed together as
a composite variate referred to as Pain Impact. Exercise frequency was similar
across the 3 groups (median=1.5 times per day). No differences were found
between groups on Pain Impact p=0.714) or individual pain variables. Most
satisfaction survey item scores did not differ between groups. However, a
significant difference between groups on the survey item related to discomfort.
The resistance and stretching group differed from the control group with regard
to their perception that the exercises were helpful in reducing discomfort in
the back and neck (p<0.001). We conclude that most subjects found the
resistance and the stretching exercises easy to do, performed them 1 to 2 times
daily, and said they reduced discomfort. To determine optimal type and
frequency of at-work exercises, further study is needed.
