Effects Of Ice Hockey Facial Protectors On The Response Time And Kinematics In Goal-Directed Tasks, P M. Dowler, D J. Pearsall, P J. Stapley
Dr Paul J Stapley
Ice hockey facial protectors are essential to prevent eye (and, in some cases, dental) injuries but must also not encumber vision and, in turn, playersapos; performance. The purpose of this study was to investigate the effects of three different facial protection conditions on temporal and kinematic parameters in a goal-directed pointing task: helmet (control), visor, and cage. Start and end target switches captured temporal estimates (reaction time (RT), movement time, (MT), and response time (RT+MT)), while a 13-light target array and 6-camera Vicon Mx system were used to collect upper-body kinematics data (head and thorax orientation, shoulder and elbow joint …

Subtalar joint instability is hypothesized to occur after injuries to the calcaneofibular ligament (CFL) in isolation or in combination with the cervical and the talocalcaneal interosseous ligaments. A common treatment for hindfoot instability is the application of an ankle brace. However, the ability of an ankle brace to promote subtalar joint stability is not well established. We assessed the kinematics of the subtalar joint, ankle, and hindfoot in the presence of isolated subtalar instability, investigated the effect of bracing in a CFL deficient foot and with a total rupture of the intrinsic ligaments, and evaluated how maximum inversion range of …

Growing interest in the underlying mechanisms of an equine spine in motion has yielded very informative data. In the beginning most of the knowledge on functional anatomy of the back was provided by dissections on cadavers. With time, the approach to the subject changed and new techniques like the use of high speed cameras for collection of kinematic and kinetic data and electromyography techniques were employed. Gaits such as walk, trot, and canter are studied in more detail for the magnitude of movements of different segments of the spine during a stride, and for the temporal pattern of the muscular …
