Introduction and aims: The aim of this
feasibility study was to evaluate a portable
biofeedback device on a group of computer
workers with musculoskeletal pain. The EMG
biofeedback was given directly on the computer
screen of each participant’s workplace
by means of specially designed software.
Methods: The wireless biofeedback device
was used by 22 office employees, who
worked at least 70 % of their regular working
hours at the computer, over a period of
four weeks. In addition to the continuously
recorded EMG data and the type and intensity
of musculoskeletal pain, the degree of
impairment by pain and psychological symptoms
such as anxiety and depression were
also measured.
Results: Continuous EMG biofeedback in this
setting seemed to reduce the maximum pain
scores as well as the degree of impairment
by pain. These positive effects still remained
detectable at follow-up four weeks after the
training. Continuous EMG biofeedback at the
occupational computer workstation seems
to be a promising treatment approach which
should be investigated further using controlled
studies and larger group sizes.
