Brief Summary

The objectives of the study are to evaluate core stability and static and dynamic balance performance in adult female hip-hop dancers and compare these scores with those of healthy non-dancer females; to obtain the injury history of dancers in the last year; to follow the occurrence of new injuries for three months; and to examine the relationship between these physical performance scores and injuries. At baseline, the hip-hop group and the non-dancer group will undergo physical performance tests. At baseline, the hip-hop group will complete a survey asking about injury history in the past year, then complete an online survey each week for three months for injury surveillance.

Outcome Measures

Primary Outcomes (3)

• Total Number of All Physical Complaints

  The term "injury" refers to anatomic tissue-level impairment as diagnosed by a physician that results in full-time loss from activity for one or more days beyond the day of onset. "Activity" in this definition means participation in a class, rehearsal, or performance. For those events that do not rise to the level of a reportable injury event within the surveillance system, the term "musculoskeletal complaint" should apply. However, since it was anticipated that dancers would rarely seek medical attention or continue dancing despite the problems they experienced, these two terms (injury and musculoskeletal complaints) were grouped under the title "all physical complaints."

  Upon completion of the three-month injury surveillance

• Core Endurance Performance

  The maximum amount of time spent maintaining the correct position in each of the flexor, extensor, and bilateral side bridge tests. The time will be recorded in seconds.

  At baseline

• Balance Performance

  For the assessment of static balance, the maximum amount of time and mean time spent maintaining the correct position in the unipedal stance test (performed both with eyes open and with eyes closed for both legs). The time will be recorded in seconds. Each trial will last a maximum of 45 seconds. For the assessment of dynamic balance, the maximum reach distance and normalized reach distance (reach divided by leg length × 100) for three directions (anterior, posterolateral, and posteromedial) in the modified star excursion balance test (for both legs). Reach distance and leg length will be measured in centimeters. A composite score is derived by averaging normalized reach distances across the three directions.

  At baseline

Study Arms (2)

Hip-Hop (Cohort)

The hip-hop dancer group will be assigned to core stability and balance performance tests as well as injury surveillance for three months.

Non-dancer (Control)

This control group will be assigned to core stability and balance performance tests only for comparison with the hip-hop dancer group and will not be subject to any injury monitoring.

Eligibility Criteria

• Age: 18 Years+
• Sex: female
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The hip-hop dancer group will consist of adult, healthy female dancers registered to dance schools in İzmir. The control group will consist of adult, healthy, non-dancer female participants. Participants will be recruited for the study through an invitation to volunteer.

You may qualify if:

• For the hip-hop group:
• Being 18 years of age or older
• Being healthy and without any initial musculoskeletal injuries
• Competing in the adult category in the hip-hop dance discipline
• For the control group:
• Meeting the first two criteria mentioned above
• Not being a dancer

You may not qualify if:

• History of spinal or abdominal surgery
• Pregnancy
• Use of medications that may affect balance
• Visual and balance impairment (for any reason)
