title: [Analysis and evaluation of occupational accidents in dancers of the dance theatre].
abstract: BACKGROUND
  The dance theatre is an autonomous form of presentation within the performing arts. It is a combination of dance, drama, singing and speaking. As the actors are usually professional dancers the dance theatre is associated with the professional dance. Compared with other dance styles there is an enhanced usage of props, costumes or décor to intensify the production and the expressiveness. In contrast to the defined professional dance technique the range of movements is unlimited. There has not yet been done any research on the influence of props as well as décor in terms of exogenous factors potentially favouring injuries. Aim of this study is to characterize specific injury patterns, as well as their causes and to suggest basic approaches to prevent injuries in the dance theatre.
  
  
  METHODS
  The data of this evaluation comprise occupational accident reports, accident reports of various Berlin theatres as well as case records of all Berlin State Theatres (n = 1106) of the Berlin State Accident Insurance over a 9-year period. 103 occupational accidents are accounted for the dance theatre.
  
  
  RESULTS
  44.6 % of the accidents happen during rehearsals, 42.4 % during performances, 76.7 % on stage and adjoining areas and 10.7 % in the ballet studio. Second most common movement resulting in an injury are jumps with 25.4 %. Altogether 69.7 % of the accidents have a uniquely defined exogenous cause with 30.5 % by props, 12.7 % by the floor and 17.2 % by the dance partner. 30.3 % of the accidents have multifactorial causes (e. g. the social situation, state of training and nutrition). 61 % of all accidents happen within three hours after starting work with an increase of occupational accidents between 11:00 - 12:00 hrs and 08:00- 09:00 hrs. The lower extremity is the most affected location (53.3 %), followed by the head/neck area (21.4 %) and the upper extremity (17.5 %). Contusions (26.2 %), distortions (17.5 %), muscular strains (19.4 %) and wounds (13.6 %) are the most frequent types of injuries.
  
  
  CONCLUSIONS
  In combination with the partly undefined movement pattern the majority of the acute injuries is - compared to other dance styles - above all caused by susceptible exogenous factors. Corrections of the daily routine, the working conditions, state of training as well as of the state of nutrition of the dancers may be initial steps towards injury prevention. At that, early interactions and interventions in the planning process of a dance theatre production could help to minimize the amount of accidents caused by exogenous factors and contribute to a practicable injury prevention in the dance theatre.
