The study of correlation between electromyography and Back-Pain Levels

The study aimed to investigate and compare the back-pain level peak-to-peak voltage and period time of Electromyography (EMG). The sample of this study was 31 patients of Yasothon Hospital. The instrument consisted of an electrocardiography (EKG monitor). For statistical analysis t-test and f-test were employed. The findings revealed that mean is The Back-Pain level of most patients was 2 (35.5 %). The peak-to-peak voltage of Back-Pain levels (1-5) were 0.11 0.12 0.21 0.25 and 0.20 mV. While period time of Back-Pain levels (1-5) were 0.85 0.86 0.86 0.62 and 0.68 s. respectively. The peak-to-peak voltage of Back-Pain levels (1 and 2) were different levels (3 and 4) at .05 level of significant. In addition the period time of Back-Pain level (4) was different levels (1 2 and 3) at .05 level of significant
