This study pertains to the 71 @entity1 who had received a diagnosis of cervico-brachial @entity158 after thorough clinical examination of a total series of 300 @entity1 , who had been referred to the National Insurance Hospital in @entity69577  s because of @entity4048 that interfered with their ability to work. Changes in trapezius muscle blood flow and EMG were examined and related to the anamnesis and physical findings. The microcirculation in the upper part of the right and left trapezius muscles was examined simultaneously by using optical laser-Doppler single-fibres after insertion into the muscle directly via the skin. Continuous recordings were made during stepwise increased static contraction determined electro-myographically. Signal processing was performed on-line by computer. MRT of the cervical spine was performed in 12 @entity1 . None showed nerve root affliction. Ten showed a bulging @entity1798 and two, a narrowed nerve hole ( @entity850 ). The muscle blood flow (LDF) was significantly lower in the most @entity158 side compared with the opposite side in the group of 41 @entity1 with predominantly @entity158 (21 @entity1 and 20 @entity1 ). A lowered blood flow was also found when the 21 females in this group was compared with a normal control group of 20 healthy @entity1 . The @entity1 had lower rms-EMG and EMG mean power frequency (MPF) in the @entity158 side compared with the opposite side. A further lowering of the MPF was observed with induced @entity1295 . It was concluded that the @entity4048 in cervico-brachial syndrome can become visualized by the finding of lowered blood flow of the trapezius muscle which seems to be an expression of the @entity4048 .
