The present study investigated the effects of advanced aging on hemispheric organization for visual-linguistic processing. Lexical decision vocal-reaction times of geriatric subjects were measured for unilaterally presented concrete and abstract nouns in an attempt to obtain an index of differential left and right hemispheric processing ability. Results of(More)
This clinical practice guideline is based on a series of systematic reviews of published studies on the treatment of symptomatic osteoporotic spinal compression fractures. Of 11 recommendations, one is strong; one, moderate; three, weak; and six, inconclusive. The strong recommendation is against the use of vertebroplasty to treat the fractures; the(More)
BACKGROUND In the last several years, the lateral transpsoas approach to the thoracic and lumbar spine, also known as extreme lateral interbody fusion (XLIF) or direct lateral interbody fusion (DLIF), has become an increasingly common method to achieve fusion. Several recent large series describe several advantages to this approach, including less tissue(More)

Decades of research have explored factors that can influence green behavior. However, much less is known about how technology in general, and social technologies in particular can motivate people to participate in green activities. In this paper we describe the goals, design and evaluation of StepGreen.org, a site intended to promote energy-saving(More)
STUDY DESIGN  Retrospective case series. OBJECTIVE  To assess fusion rates in patients with sacroiliac joint (SIJ) pain following a minimally invasive technique using fibular dowel allograft. METHODS  Thirty-seven consecutive patients (mean age: 42.5 years [range, 23-63 years]) with SIJ pain treated with 38 minimally invasive elective SIJ arthrodeses(More)
The peak amplitude of EMG activity was measured from the orbicularis oris superior, orbicularis oris inferior, and masseter muscles for 3 mild and 3 moderately articulatory disordered and 3 normal children. The three groups showed similar levels of average peak EMG activity and variance across the three muscles, suggesting that the disordered children were(More)
We describe our entry in the AAAI 2002 Urban Search and Rescue (USAR) competition, a marsupial team consisting of a larger wheeled robot and several small legged robots, carried around by the larger robot. This setup exploits compli-mentary strengths of each robot type in a challenging domain. We describe both the hardware and software architecture, and the(More)
The present study measured F1 and F2 formant frequency levels of elderly and young male and female speakers producing the /i/, /ae/, [symbol: see text], /u/, and /a/ vowels in two carrier phrases. Results of a series of ANOVAs showed significant interactions of speaker age x vowel for both F1 and F2 formant frequencies for the male and female speakers.(More)
STUDY DESIGN  Randomized controlled animal trial. OBJECTIVES  To analyze the early and late phase effects of platelet-rich plasma (PRP) injection into and around the damaged intervertebral disc using an animal model, and to evaluate the needle puncture technique in creating a degenerative disc model. METHODS  The L4-L5 intervertebral disc of 18 adult(More)
