Quantitative Measures Utilized in Determining Pointe Readiness in Young Ballet Dancers

While an important step in a young dancer's ballet career is the transition to pointe work, there is much controversy as to when her body is physically prepared to meet the increased demands of this development. Pointe screening protocols are being used by many in both the dance studio and dance science communities, but these protocols have not yet been standardized. The purpose of this study was to evaluate objectively the attributes of ballet dancers who are pre-pointe compared to those who have recently begun pointe training, and secondarily to correlate these quantitative findings with qualitative evaluations by the dancers' teachers. Participants were 49 healthy young female dancers with at least 1 year of formal ballet training. Twentyeight were pre-pointe students (age: 10.21 ± 1.17 years; height: 124.05 ± 13.45 cm; weight: 39.13 ± 13.18 kg; and 6.04 ± 1.84 years dance experience), and 21 were pointe students (age: 11.42 ± 0.81 years; height: 136.91 ± 16.04 cm; weight: 40.79 ± 8.77 kg; and 6.45 ± 2.07 years dance experience). Six dependent variables were evaluated: non-weightbearing (NWB) plantar flexion (PF) and dorsiflexion (DF) range of motion (ROM); weightbearing lunge test (WBL); relevé endurance (heel raise test); PF isometric strength; Airplane test; and Star Excursion Balance Test (SEBT) in three directions. These tests were broken into three categories for statistical analysis: ROM (NWB PF and DF, WBL), muscular capacity (relevé endurance, PF isometric strength), and balance (Airplane, SEBT). The analysis demonstrated that the pointe group performed significantly better than the pre-pointe group on the muscular capacity and balance testing (p < 0.01). Calculations for both tests indicated that 15 continuous single-leg relevés and two repetitions of the Airplane test may be the best cut-off levels when using these tests as part of a pre-pointe screening protocol. In conclusion, the relevé endurance test and the Airplane test are appropriate for use in differentiating between pre-pointe and pointe dancers.
