“…With regard to the inclinometric plantar flexion measurement method of Novella, 5,6 we found this method to be not comparable to goniometric measurement of plantar flexion. Values obtained by this inclinometry technique require a conversion to compare them to traditional goniometry values, a task accomplished by adding 90 to the inclinometric plantar flexion values.…”

“…The inclinometer plantar flexion (IPF) technique was adapted from the method of Novella. 5,6 Novella used the tendu ballet position (ie, his subjects stood holding their lower extremity with slight hip flexion, knee extension, and plantar flexion). However, for this research, the identical seated position was selected as that used for the plantar flexion goniometry.…”

“…[1][2][3] This is particularly exemplified by the plantar flexion needed to rise en pointe (Figure 1). [3][4][5][6] Such extremes challenge ankle rangeof-motion assessment in ballet dancers because the motion is greater than normative data reported for the ankle using goniometry. 7,8 In light of this, the standardization of methods to measure ankle range of motion in female ballet dancers is important for improved understanding of the demands of ballet on this joint and surrounding structures and for measurement of ballet dancers' ankle range of motion during rehabilitation from ankle injury or surgery.…”

“…While various studies have measured ankle range of motion in ballet dancers, 3,5,[9][10][11][12][13][14][15][16] none could be found comparing different measurement techniques nor evaluating motion in the weightbearing positions of demi-plié (maximum dorsiflexion) and en pointe (maximum plantar flexion). Therefore, the primary aims of this project were to determine whether non-weight-bearing ankle range of motion is significantly different from weight-bearing ankle range of motion in demi-plié and en pointe and whether inclinometric plantar flexion measurement as proposed by Novella 5,6 is a suitable substitute for standard plantar flexion goniometry.…”

Female ballet dancers require extreme ankle motion, especially plantar flexion, but research about measuring such motion is lacking. The purposes of this study were to determine in a sample of ballet dancers whether non-weight-bearing ankle range of motion is significantly different from the weight-bearing equivalent and whether inclinometric plantar flexion measurement is a suitable substitute for standard plantar flexion goniometry. Fifteen female ballet dancers (5 university, 5 vocational, and 5 professional dancers; age 21 ± 3.0 years) volunteered. Subjects received 5 assessments on 1 ankle: non-weight-bearing goniometry dorsiflexion (NDF) and plantar flexion (NPF), weight-bearing goniometry in the ballet positions demi-plié (WDF) and en pointe (WPF), and non-weight-bearing plantar flexion inclinometry (IPF). Mean NDF was significantly lower than WDF (17° ± 1.3° vs 30° ± 1.8°, P < .001). NPF (77° ± 2.5°) was significantly lower than both WPF (83° ± 2.2°, P = .01) and IPF (89° ± 1.6°, P < .001), and WPF was significantly lower than IPF (P = .013). Dorsiflexion tended to decrease and plantar flexion tended to increase with increasing ballet proficiency. The authors conclude that assessment of extreme ankle motion in female ballet dancers is challenging, and goniometry and inclinometry appear to measure plantar flexion differently.

“…23,54 The total ROM required to attain the extreme PF ROM during dance movement is proposed to come from a summation of movement from all of these aforementioned joints in the foot-ankle complex. 23,55,56 Therefore, evaluating functional foot and ankle ROM of dancers requires a measure of 1. total ROM, 2. inter-segmental ROM, and 3. individual foot and ankle joint ROM in the foot-ankle complex. 1,4,6,57 Three-dimensional (3D) motion capture systems to study the kinematics of joint segments of joint segments are being used more frequently in research laboratories and clinics for analyzing gait because of the system's ability to measure the foot and ankle in all three planes of movement (sagittal, frontal, and transverse).…”

Applications of Biomechanical Foot Models to Evaluate Dance Movements Using Three-Dimensional Motion Capture: A Review of the Literature

Dance movement requires excessive, repetitive range of motion (ROM) at the foot-ankle complex, possibly contributing to the high rate of injury among dancers. However, we know little about foot biomechanics during dance movements. Researchers are using three-dimensional (3D) motion capture systems to study the in vivo kinematics of joint segments more frequently in dance-medicine research, warranting a literature review and quality assessment evaluation. The purpose of this literature review was to identify and evaluate studies that used 3D motion capture to analyze in vivo biomechanics of the foot and ankle for a cohort of dancers during dance-specific movement. Three databases (PubMed, Ovid MEDLINE, CINAHL) were accessed along with hand searches of dance-specific journals to identify relevant articles through March 2020. Using specific selection criteria, 25 studies were identified. Fifteen studies used single-segment biomechanical foot models originally created to study gait, four used a novel two-segment model, and six utilized a multi-segment foot model. Nine of the studies referenced common and frequently published gait marker sets and four used a dance-specific biomechanical model with purposefully designed foot segments to analyze the dancers’ foot and ankle. Description of the biomechanical models varied, reducing the reproducibility of the models and protocols. Investigators concluded that there is little evidence that the extreme total, segmental, and inter-segmental foot and ankle ROM exerted by dancers are being evaluated during dance-specific movements using 3D motion capture. Findings suggest that 3D motion capture is a robust measurement tool that has the capability to assist researchers in evaluating the in vivo, inter-segmental motion of the foot and ankle to potentially discover many of the remaining significant factors predisposing dancers to injury. The literature review synthesis is presented with recommendations for consideration when evaluating results from studies that utilized a 3D biomechanical foot model to evaluate dance-specific movement.
