Context: Physicians and clinicians need portable, efficient, and cost-effective assessment tools to determine the effectiveness of rehabilitation programs after knee injury. Progress in rehabilitation should be evaluated using valid and reliable measurement methods. Objective: To examine the test-retest reliability of portable fixed dynamometry (PFD), handheld dynamometry (HHD), and isokinetic dynamometry (IKD). In addition, the authors sought to examine the validity of PFD and HHD by comparing differences in peak torque of the knee flexors and extensors to that of the "gold standard" IKD. Design: Repeated measures. Participants: 16 healthy subjects (age 29.3 ± 7.2 y, height 167.4 ± 8.04 cm, mass 73.7 ± 20.0 kg). Main Outcome Measures: The dependent variables were trial (trial 1, trial 2) and instrument (IKD, PFD, and HHD). Results: Test-retest reliability was high for both PFD and IKD. However, fair to poor reliability was found for HHD. There were no differences in peak torque (Nm) between IKD and PFD. However, significant differences in peak torque were observed between IKD and HHD and between PFD and HHD. Conclusions: PFD provides reliable measures of strength and also demonstrates similar output measures as IKD. Its portability, ease of use, and cost provide clinicians an effective means of measuring strength.

Context:

Dissemination of information regarding the latest research findings in rehabilitative health care is often limited to professional journals.

Objective:

The purpose of the paper is to describe opportunities to better distribute scientific information to wider swaths than normally contained within a readership of a journal, to describe a process to deliver important information via the Cooperative Extension Service, and provide an example of such an informational brochure.

Design:

An interdisciplinary approach was developed to provide access to a larger cohort of individuals the latest research findings regarding heat and hydration.

Data Extraction:

CINAHL, Medline, and Sport Discus were reviewed from 1966 to 2006 using the terms Heat, Hydration, Rhabdomyolysis, Rehabilitation, Heat Exhaustion, Heat Stroke, and Dehydration.

Data Synthesis:

We found substantial information describing recommendations for preventing, recognizing, and treating illness due to variance in heat and hydration. The information was succinctly summarized, converted to a 7th grade reading level, and shared with a larger audience via a unique model available through Cooperative Extension Agencies.

Conclusion:

Providing scientific information via a Cooperative Extension Model enables sharing of information from experts to communities. This methodology increases the distribution of the latest scientific knowledge to broader audiences.
