OBJECTIVES To establish the reliability, accuracy and concurrent validity of electrogoniometers for measuring extreme lower extremity movements. STUDY DESIGN Reliability, accuracy and validity study. METHODS This project employed two experiments. Investigation I determined electrogoniometer accuracy compared to a digital protractor. Investigation II(More)
Using functional near infrared spectroscopy (fNIRS) we studied how playing a dance video game employs coordinated activation of sensory-motor integration centers of the superior parietal lobe (SPL) and superior temporal gyrus (STG). Subjects played a dance video game, in a block design with 30s of activity alternating with 30s of rest, while changes in(More)
Biomechanical analysis is a powerful tool in the evaluation of movement dysfunction in orthopaedic and neurologic populations. Three-dimensional (3D) motion capture systems are widely used, accurate systems, but are costly and not available in many clinical settings. The Microsoft Kinect™ has the potential to be used as an alternative low-cost motion(More)

Analysis of skill at multiple points on the learning continuum provides insight into how complex limb and postural organization is modified with extended practice. Dancers at three skill levels were compared performing a domain-specific movement (développé arabesque) to identify motor control parameters underlying skill acquisition of a sequential(More)
Symmetry of skill development is emphasized in dance training, and many movements are well learned by both genders. The authors conducted a 2-dimensional kinematic analysis of a complex dance movement, the passé, in 12 healthy professional male and female dancers to determine whether there are differences between genders or limbs during the performance of(More)
We utilized the high temporal resolution of functional near-infrared spectroscopy to explore how sensory input (visual and rhythmic auditory cues) are processed in the cortical areas of multimodal integration to achieve coordinated motor output during unrestricted dance simulation gameplay. Using an open source clone of the dance simulation video game,(More)
Dancers frequently sustain hip injuries, including labral tears, coxa saltans, stress fractures, tendinosis, and joint disease. High velocity kicks (grand battement), with extreme abduction and external rotation (ER), may stress the hip, sacroiliac joint, and surrounding soft tissue. However, three-dimensional kinematic dance descriptions are limited. The(More)
The Kana Pick-out Test (KPT), which uses Kana or Japanese symbols that represent syllables, requires parallel processing of discrete (pick-out) and continuous (reading) dual tasks. As a dual task, the KPT is thought to test working memory and executive function, particularly in the prefrontal cortex (PFC), and is widely used in Japan as a clinical screen(More)
We present a method to compare brain activity recorded with near-infrared spectroscopy (fNIRS) in a dance video game task to that recorded in a reduced version of the task using fMRI (functional magnetic resonance imaging). Recently, it has been shown that fNIRS can accurately record functional brain activities equivalent to those concurrently recorded with(More)
Ankle injuries are the most common lower extremity injury in dance and sports, often resulting in limitation of dorsiflexion or plantar flexion. Accurate assessment of any limitation in range of motion is an important factor in implementing effective preventative and rehabilitative regimens. Ankle range of motion has traditionally been quantified with(More)
