Study type | Interventional |
An experimental study will be conducted to evaluate the effect of a single dry needling session, compared to a sham needling session, on surface EMG activity (signal amplitude and frequency) and pain of the upper trapezius muscle, in office workers with trapezius myalgia.

Primary | Changes in resting surface EMG activity (amplitude, RMS) of the upper trapezius after dry needling or sham needling as assessed by the EMG Noraxon 16k Telemyo Device: EMG Noraxon 16k Telemyo | Changes in resting EMG activity (amplitude, Root Mean Square) of the upper trapezius immediately after, 15 minutes and 30 minutes after dry needling, compared to EMG activity after a typing task, will be measured using surface electrodes placed bilaterally at the MTrP location of the upper trapezius. The change in resting surface EMG activity after dry needling will be compared with the change in surface EMG activity after sham needling.
Resting surface EMG activity will be expressed as a percentage of a submaximal reference contractions of the upper trapezius (% reference contractions) |
Immediately after a typing task of 20 minutes, immediately after dry or sham needling, 15 minutes and 30 minutes after dry or sham needling | |
Secondary | Changes in surface EMG activity (amplitude, Root Mean Square) of the upper trapezius during a fatiguing typing task of 20 minutes as assessed by the EMG Noraxon 16k Telemyo Device: EMG Noraxon 16k Telemyo | Changes in EMG activity (amplitude, Root Mean Square) of the upper trapezius during a typing task of 20 minutes, will be measured by using surface electrodes placed bilaterally at the MTrP location of the upper trapezius.
EMG activity during this typing task will be expressed as a percentage of submaximal reference contractions of the upper trapezius (% reference contractions). |
During the typing task, every five minutes EMG activity will be measured for 30 seconds | |
Secondary | Changes in pain score after dry needling, compared to sham needling, as assessed by the numeric rating scale | Subjects will have to report their actual pain complaints on a numeric rating scale (NRS) ranging from 0 (no pain) to 10 (worst pain) after a typing task, immediately after dry or sham needling, 15 minutes after dry or sham needling and 30 minutes after dry or sham needling. In the 7 days following the treatment, pain scores will be asked daily to the participants. | Immediately after a typing task of 20 minutes, immediately after dry or sham needling, 15 minutes after dry or sham needling, 30 minutes after dry or sham needling, daily during the seven days following the treatment | |
Secondary | Changes in pain score after a typing task of 20 minutes as assessed by the numeric rating scale | Subjects will have to report their actual pain complaints on a numeric rating scale (NRS) ranging from 0 (no pain) to 10 (worst pain) before and after a typing task of 20 minutes. | Immediately before and after a typing task of 20 minutes |
