Summary

Range of motion and balance ability might also contributed to injuries and disorders of breaking like other sports

Abstract

【Introduction】
Breaking, one type of street dance, is known for higher rates of musculoskeletal injuries compared with other kind of street dances. Although injury prevention was necessary for dancers, the characteristics of injuries related to breaking were not clarified. The purpose of this study is to compare the injury demographics, balance ability, and range of motion (ROM) between breaking dancers and other kind of street dancers.
【Material and method】
In this case-control study, 52 dancers (16 females, 36 males:) were participated in this study. Mean age was 26.2± 4.2 years old. We investigated injury rate, location, ROM, and balance ability.The ROMs were measured in shoulder, elbow, hand, hip, knee and ankle. We evaluated balance ability using Star Excursion Balance Test (SEBT). The participants were divided into breaking dancers group or other kind of street dancers group. We compared two groups about evaluation issues using Student’s t-test and chi-square test. Statistical significance was set at P < 0.05.
【Result】
23 were included in breaking dancer group, and 29 were included in other kind of street dancers group. Proportion of other kind of street dancers group,34.5% were Lock, 24.1% were Waack, and 17.2% were pop. Injury rate was 87.0% in breaking dancer group and 57.3% in other kind of street dancers group. The most commonly injured body parts was hand and hip in breaking dancer group and Shoulder in other kind of street dancers group.
The ROM of adduction and extension of the hip, external rotation of the shoulder, dorsiflexion of the hand in breaking dancer group were significantly lower than those values of other kind of street dancers group.
In breaking dancer group, SEBT score  of anterior, anterolateral, and lateral posterolateral were worsen.
【Discussion】
Balance ability and ROM of breaking dancers were significantly worse compared from those values of other kind of street dancers.
Performance of breaking requires touching the ground by hand and shoulders repeatedly. Therefore, it was believed that the musculoskeletal injuries of the breaking dancers were occurred at hand of shoulders. Our results indicated that the injury ratio of the hip was also high. It suggested that the upper limb and hip should be focused to injury prevention concerning about breaking dancers.
On the other hand, this study revealed that the decreasing ROM and balance ability might also contributed to injuries and disorders of breaking. It was thought that the injury prevention program for breaking dancers should be constructed.
