Motor control and low back pain in dancers

Area of Science:

• Dance Science
• Sports Medicine
• Rehabilitative Medicine

Background:

• Professional dancers have a high injury rate, particularly in the spine and lower extremities.
• Low back pain (LBP) is prevalent in dancers, yet experimental research is limited.
• Understanding LBP in dancers is crucial for injury prevention and performance enhancement.

Purpose of the Study:

• To compare lumbopelvic motor control, muscle extensibility, and sacroiliac joint pain in dancers with and without LBP history.
• To investigate potential risk factors associated with LBP in pre-professional dancers.
• To contribute to the understanding of the etiology of LBP in this athletic population.

Main Methods:

• A cohort of 40 pre-professional dancers (mean age 20.3 years) was assessed.
• Clinical tests evaluated lumbopelvic motor control, muscle extensibility, joint hypermobility, and sacroiliac joint pain.
• Self-reported measures and standardized questionnaires were utilized to gather data on LBP history.

Main Results:

• 41% of dancers reported LBP lasting at least two consecutive days in the past year.
• Dancers with a history of LBP demonstrated significantly poorer lumbopelvic motor control (p<0.05).
• No significant differences were found in muscle extensibility or generalized joint hypermobility between groups (p>0.05).

Conclusions:

• Pre-professional dancers experience a high incidence of LBP, even at a young age.
• Sacroiliac joint pain, hypermobility, and muscle extensibility do not appear to be primary factors in LBP for this group.
• Impaired lumbopelvic motor control is associated with LBP history in dancers, warranting further etiological investigation.
