Vulnerability to xylem embolism by freeze-thaw cycles and water stress was quantified in ring-porous (Quercus gambelii Nutt.), diffuse-porous (Populus tremuloides Michx., Betula occidentalis Hook.), and conifer species (Abies lasiocarpa Nutt., Juniperus scopulorum Sarg.). Embolism was measured by its reduction of xylem hydraulic conductivity; it was induced(More)
The purposes of the study were to determine the reliability of a new device used to quantify shoulder subluxation and to estimate its standard error of measurement. The device is an L-shaped thermoplastic jig with a metric tape measure embedded in it. A sliding beak-like marker, which can be anchored with a thumbscrew, is used to identify landmarks and to(More)
Standardized outcome measures (OMs) are a vital part of evidence-based practice. Despite the recognition of the importance of OMs, recent evidence suggests that the use of OMs in clinical practice is limited. Selecting the most appropriate OM enhances clinical practice by (1) identifying and quantifying body function and structure limitations; (2)(More)
Physical therapists working in neurological practice must make choices about which standardized outcome measures are most appropriate for each patient. Significant time constraints in the clinic limit the number of measures that one can reasonably administer. Therapists must choose measures that will provide results that guide the selection of appropriate(More)
BACKGROUND AND PURPOSE The use of standardized outcome measures (OMs) can support clinicians' development of appropriate care plans, guide educators in curricular decisions, and enhance the methodological quality and generalizability of clinical trials. The purposes of this case report are: (1) to describe a framework and process for assessing psychometrics(More)
This case report examined the effectiveness of a home program using neuromuscular electrical stimulation (NMES) during voluntary task-oriented exercise to achieve functional and impairment improvements for an individual with primarily proximal arm paresis after a stroke. The subject initially achieved a Fugl-Meyer Assessment (FMA) score of 58/66, but she(More)
BACKGROUND Sensory amplitude electrical stimulation (SES) and repetitive task practice reduce impairments and arm dysfunction when delivered separately following stroke. OBJECTIVE To determine if home-based, task-specific arm exercise was more effective when administered concurrent with SES. METHODS Thirty-eight subjects with chronic stroke and mean(More)
The periapical areas of 16 teeth from 6 human mandibular jaw specimens were randomly examined by 3 observers using conventional radiography with Kodak E-speed film and radiovisiography (with variable contrast and with fixed contrast). Each periapical area was examined preoperatively and after #2, #4, #6, and #8 sized bur periapical lesions were created in(More)
OBJECTIVE To explore the viability of the perceptual threshold test using electrical stimulation to measure light touch sensation in the hands of stroke survivors. DESIGN Descriptive study. SETTING University research laboratory. SUBJECTS Twenty-nine adult community-dwelling chronic stroke survivors. MAIN MEASURE(S): Perceptual threshold test using(More)
Background: Sensory amplitude electrical stimulation (SES) and repetitive task practice reduce impairments and arm dysfunction when delivered separately following stroke.
