Research On Non-specific Low Back Pain Of Chinese Classical Dancers

Classical dance specialty,the difficulty,amplitude and speed of dancers' waist training are required to be higher,and the waist plays an important role in carrying and generating power during the training process.Therefore,as a classical dance professional dancer,the waist a high injury rate and is easily repeated.The waist is a part of dancers with high injury rate and is easily repeated.There are no clear pathological changes in the tissue structure of this recurrent waist injury in the objective medical examination,which is medically called nonspecific low back pain.Taking the classical dance specialty as the point of penetration,this paper explores the causes of nonspecific low back pain injury of dancers by questionnaire,and designs targeted rehabilitation training according to the survey results,so as to help dancers alleviate the problems caused by nonspecific low back pain and provide a certain reference for the dancers in the selection of rehabilitation treatment methods.The results of the study showed that: 1.The waist injury is common in dancers,The causes for the waist injury of dancers are as follows: frequent,repeated use of the waist,insufficient preparation activities,difficult classroom training intensity,long corrective action or rehearsal time,and lack of attention to keep warm and warming-up activities;2.Chinese classical dance professional nonspecific low back pain dancers can easily lead to changes in the morphology and structure of the vertebral body,thus forming some unhealthy posture,including: flat back posture,contracted waist posture,scoliosis;3.Non-specific low back pain dancers of Chinese classical dance have imbalance of muscle strength on both sides of the waist.Muscle strength was higher in the direction of lumbar flexion and extension,and the extensor muscle strength was higher than the flexor muscle strength,the imbalance of muscle strength of lateral flexion left side and right side,rotation leftward and rightward was more serious;4.The content of rehabilitation training is based on the principle of combining static and motive force,stability and instability,and strengthening relaxation training at the same time.The design of rehabilitation training action includes static bodyweight training,dynamic bodyweight training,instrument assisted training,waist relaxation training(language guidance,bodyweight static stretching,fascia ball assisted massage);In the intervention program designed according to the above principles,the muscle strength of dancers was significantly improved and the pain score showed a decreasing trend.Theexperimental results showed that the rehabilitation training content alleviated the symptoms of non-specific low back pain,which proved that the intervention plan was feasible.
