 PDF
- To find the severity and the type of the cervicobrachial syndrome, through physical examinations and laboratory tests were made toward 137 patients complaining the cervicobrachial syndrome (CBS) through the health interview among 313 workers occupied in a microwave-oven assembling factory from December 1993 to February 1994.
Results
were as follows.
1. The prevalence of spontaneous pain was 94.9%, while 78.1% suffered from muscle tenderness, 63.5% suffered from muscle induration and 62.0% showed kinesalgia. 54.7% of patients showed positive cervical X-ray findings and 28.5% showed positive Morley test.
2. The muscle induration was associated with the total duration of the job among female workers.
3. The severity of neck tenderness was negatively correlated with the strength of the grip at both hands, positively correlated with the duration of overtime in male and the severity of the wrist tenderness was negatively correlated with the height in female.
4. X-ray findings, muscle induration, Morley test results, muscle tenderness on the neck and muscle tenderness on the shoulder were associated with subjective symptoms of the workers.5. The muscle tenderness was associated with the number of the complaints at upper extremities among the sufferings in daily life significantly and the electromyogram (EMG) finding was associated with; the number of the complaints: about neuropsychological system among the sufferings in daily life significantly.
In conclusion, the results of the physical examination were related with the subjective symptoms of the cervicobrachial syndrome. The muscle induration, the muscle tenderness, cervical X-ray findings and the Morley test results were more useful for the diagnosis of CBS. More efforts to objectify the subjective symptoms were asked.
