Objective : To investigate the effects of Thai dancing on median neurodynamic response during 4-hour computer use.
Material and Method: Twenty-four healthy participants aged 20-30 years performed 5 minutes of Thai dancing including
Prom See Na, Yoong Fon Hang, Sod Soy Mala, Lor Keaw and Cha Nee Rai Mai during a 10-minute break of 4-hour computer
use. All participants were assessed for nerve tension by elbow range of motion of upper limb neurodynamic test 1 (ULNT1)
and components of quick test. The discomfort was measured by visual analogue discomfort scale (VADS). These measure-
ments were assessed before and after computer work. The statistical analyses employed paired t-test for continuous outcome
and Friedman’s test.
Results : The median nerve tension (indicated by elbow range of motion) was significantly reduced at before and after work,
when 5 minutes of Thai dancing was introduced during the break. While components of the quick test emphasized that Thai
dance immediately helped reduce the median nerve tension. The VADS in eight body areas increased over the period of 4
hours, but decreased after performing Thai dancing (p<0.05).
Conclusion : Thai dancing helped relieve median nerve tension and body discomfort. It may be recommended as an exercise
during break for computer users who continuously work to prevent WMSDs.
