Rationale: The Dance-Specific, Graded Rehabilitation program (DSGRP) was first published by dance-specialized orthopedists in 2008. Used for reconditioning and monitoring rehabilitation, the program comprises of dance-specific, graded activities. The program is built on the progression of three factors: (1) movement (relevé – heel raises, explosive relevé – heel raises with the intention to jump but not actually jumping, and sauté – small jumps), (2) leg support (two legs and one leg), and (3) barre support (two hands, one hand and no hands on the barre). However, the progression of the program and the factors on which it is based are yet to be fully biomechanically analyzed.
Purpose: The aim of the present study is to analyze the influence of movement, leg support, and barre support on weight bearing and impact characteristics in the progressive stages of DSGRP.
Methods: Eighteen participants with dance experience performed four consecutive repetitions of each stage of the DSGRP in a semi-randomized order. The resulting forces were collected with each foot on one AMTI force plate, while full body kinematics were recorded with an Optitrack motion capture system. Weight bearing was quantified as the peak vertical force in each stage; whereas impact characteristics were quantified by takeoff and landing loading rates (the difference between the maximum and minimum vertical forces divided by the time between these two events) and impulse (the area under the force time curve). After manipulation checks for expected differences between two-leg and one-leg performance, two two-way ANOVAs were performed considering movement and barre support for two-leg and one-leg stages, respectively.
Results: Overall, manipulation checks confirmed increases in weight bearing and impact characteristics when progressing from two-leg to one-leg strategies. For all analyzed variables, main effects were found for movement; while no main effects were found for barre support, expect in the impulse of one-leg stages. The interaction movement x barre support was not significant for all variables.
Conclusion: Biomechanical analysis of the three factors making up the DSGRP reveal increasing weight-bearing and impact characteristics with movement type and leg support, though little effect of barre support. The incremental effects of observed factors inform correct sequencing for rehabilitation protocols to help dancers return to dance safely.
