BACKGROUND: Lion dance is an art-sport growing rapidly around the world. Movement patterns involved in lion dance put the lion dancers at high risk of spinal injury. However, report on spinal injury in lion dancers is not yet available. This study aimed to obtain radiologic imaging of the spine of lion dancers and to evaluate the association between abnormal imaging and players’ position.
METHODS: Twenty eight controls and 15 pairs of lion dancers (30 players) from the National Lion Dance Championship were involved. Anthropometric measurements and questionnaire were used. Spine X-ray was conducted using a radiography system (XR6000, GE, USA) in AP and lateral views. Difference and association between groups or variables was evaluated using appropriate statistical test. Logistic regression was used to determine the odds ratio (OR). Significance was set at P<0.05.
RESULTS: Lion dancers and control have similar age and measurements. Lion dancers was seen to have more spine abnormality (OR 39, CI 95%: 8.80-173.5, P≤0.001). Among the lion dancers, most tail players were heavier and taller. Age, age at which they began to practice, duration of practice, and frequency of training were not different between groups (P>0.05). Of 30 players, 26 (86.7%) had abnormalities in the spine. There were 39 spine abnormalities from 26 players. The most common abnormality was mild scoliosis (23 cases/59%). Frequency of spine abnormalities and affected segment had no association with players’ position.
CONCLUSIONS: Spinal abnormalities are common in lion dancers. However, frequency of abnormality and differences in affected spinal segments have no relationship with players’ position.
