This study examined the effects of passive stretching only (PS+CON) and passive stretching with the addition of continuous vibration (VIB) during post-passive stretching tests (PS+VIB) on peak torque (PT), percent voluntary inactivation (%VI), single stimulus twitch torque (TTSINGLE), and doublet stimuli twitch torque (TTDOUBLET) of the plantar flexors at a short (20° plantar flexion (PF)) and ...

Two of the most common reasons for failure to obtain adequate preoperative functional data are inadequate task performance and excessive head motion. With an MR imaging-compatible pneumatically driven manipulandum, passive motor tasks elicited reproducible contralateral activation in the M1 and S1 in 10 healthy controls and 6 patients. The SMA was localized in all healthy controls and in 5 of 6...

BACKGROUND AND PURPOSE Functional brain mapping is an important technique for neurosurgical planning, particularly for patients with tumors or epilepsy; however, mapping has traditionally involved invasive techniques. Existing noninvasive techniques require patient compliance and may not be suitable for young children. We performed a retrospective review of our experience with passive-motion fu...

BACKGROUND Femoroacetabular impingement is a debilitating hip condition commonly affecting athletes playing American football. The condition is associated with reduced hip range of motion; however, little is known about the range-of-motion demands of football athletes. This knowledge is critical to effective management of this condition. PURPOSE To (1) develop a normative database of game-lik...

This study examined whether hydrotherapy per formed in bubble baths improves knee range of motion in patients who have undergone total knee arthroplasty. The subjects included 11 patients (two males and nine females) who underwent unilateral total knee arthroplasty. In this study, we measured knee range o f motion test results preand post-bubble bath. The mean di fference in range o f motion te...

Johansson's point-light walker figures remain one of the most powerful and convincing examples of the role that motion can play in the perception of form (Johansson, 1973 Perception & Psychophysics 14 201 - 211; 1975 Scientific American 232(6) 76 - 88). In the current work, we use a dual-task paradigm to explore the role of attention in the processing of such stimuli. In two experiments we find...

Prototypes have been designed and manufactured for a lightweight portable device which continually moves all the joints of the hand passively through a range of motion. Inflatable bag modules in the palm of the hand are ganged together to create the required range of motion. A battery-operated air pump cycles compressed air to the modules. Initial clinical experience with patients who have flex...
