Clinicians' perspectives and usage of rehabilitation technology: a survey.

Purpose: The aim of this study was to investigate clinicians' perspectives regarding their usage of rehabilitation technology in their day-to-day practice and uncover the factors that impact clinicians' use of rehabilitation technology in their daily practice.

Materials And Methods: An online survey was used to gather cross-sectional data from American occupational therapists, occupational therapy assistants, physical therapists, physical therapy assistants, and speech language pathologists. This survey used Likert-scale, multiple choice, and free-response questions.

Relationship of occupational therapy inpatient rehabilitation interventions and patient characteristics to outcomes following spinal cord injury: the SCIRehab project.

Background/objective: Describe associations of occupational therapy (OT) interventions delivered during inpatient spinal cord injury (SCI) rehabilitation and patient characteristics with outcomes at the time of discharge and 1-year post-injury.

Methods: Occupational therapists at six inpatient rehabilitation centers documented detailed information about treatment provided. Least squares regression modeling was used to predict outcomes at discharge and 1-year injury anniversary for a 75% subset; models were validated with the remaining 25%.

Wear resistance and wear mechanisms in polymer + metal composites.

We have investigated composites containing metallic micro-size and nano-sized particles as the 10 wt% dispersed phase. Branched low density polyethylene (LDPE) was the matrix. Microsized metals were Al, Ag and Ni; nanosized metals were Al and Ag.

Slow conductances could underlie intrinsic phase-maintaining properties of isolated lobster (Panulirus interruptus) pyloric neurons.

The rhythmic pyloric network of the lobster stomatogastric system approximately maintains phase (that is, the burst durations and durations between the bursts of its neurons change proportionally) when network cycle period is altered by current injection into the network pacemaker (Hooper, 1997a,b). When isolated from the network and driven by rhythmic hyperpolarizing current pulses, the delay to firing after each pulse of at least one network neuron type [pyloric (PY)] varies in a phase-maintaining manner when cycle period is varied (Hooper, 1998). These variations require PY neurons to have intrinsic mechanisms that respond to changes in neuron activity on time scales at least as long as 2 s.

A theoretical experimental method to determine the locus of desensitization.

Consider a ligand-gated channel with n agonist binding sites which can undergo desensitization. We present a theoretical experimental procedure for pinpointing the principal receptor state from which there is a transition to the desensitized state. The method is based on the observation that the dependence of the slope of the time constant of desensitization vs agonist concentration, at low concentrations, represents the state from which desensitization occurs.
