Pressure Thresholds And Stiffness On The Plantar Surface Of The Human Foot, Thilina W. Weerasinghe, Ravindra S. Goonetilleke, Uwe Reischl

Public and Population Health Faculty Publications and Presentations

The objective was to develop a methodology to assess Pressure Discomfort Thresholds (PDT), Pressure Pain Thresholds (PPT), and tissue stiffness on the plantar surface of the foot. Ten male and ten female participants volunteered for the study. Foot landmarks were used to create a standardized grid-type template of 95 points. For each test point, PPT and PDT values were obtained, and stiffness was calculated for each of the twenty participants. Cluster analyses were performed to determine the regions of similarity for the three dependent variables, PPT, PDT and stiffness. Moran’s-I-index was used to determine the spatial auto correlations. The use …

Kinematic Repeatability Analyses Of Multi-Segment Foot Motion In University-Level Ballet Dancers, Sarah Carter, Nahoko Sato, Luke Hopper

ECU Posters

Background:

Dancers are susceptible to overuse foot and ankle injuries, however there is a lack biomechanical studies examining foot mechanics to explain the causality of these injuries. The purpose of this study was to determine the intra and inter-assessor repeatability of a modified Rizzoli Foot Model (RFM) for ballet dancers.

Methods: Six university-level ballet dancers performed the following trials in randomized order, natural stance, turnout plié and stance, and two dynamic trials; turnout rise and flex-point-flex movement. A twelve-camera motion capture system were used to track fourteen reflective markers and one triad on the following segments: shank, entire foot, hindfoot, …

Lower Leg And Foot Contributions To Turnout In University-Level Female Ballet Dancers: A Preliminary Investigation, Sarah Carter, Alan R. Bryant, Luke Hopper

ECU Posters

Functional turnout in ballet involves maximal external rotation through the lower limb kinetic chain. Hip external rotation, is considered the primary contributor of functional turnout. However, dancers will tend to increase their functional turnout angle through additional tibiofemoral external rotation and pronation of the foot/ankle complex. Hip external rotation measures in functional turnout has received extensive examination in dance science. However, the relationship between the ‘below the hip' assessments with functional turnout is poorly understood. We hypothesis that dancers with greater passive external tibiofemoral rotation (pTFR) and/or pronated stance will have a greater functional turnout angle.
