Version 11-30-2016-1 FAR Part 11—Describing Agency Needs

PURCHASE DESCRIPTION

1. Statement of Need and Purpose: NIA requires an isokinetic dynamometer.

2. Background Information and Objective: The National Institute on Aging (NIA) Baltimore Longitudinal Study of Aging (BLSA) has measured muscle strength in study participants for over 20 years. Muscle strength is an important contributor to functional performance and is directly related to neurological and metabolic control mechanisms.

NIA requires a unit that can measure strength eccentrically and concentrically to test leg strength in participants which is directly related to activities of daily living and remaining independent during aging. The current system, a Biodex System Pro, was purchased in 2009 and has reached the end of eligibility for annual service and maintenance contract.

This purchase is to replace the current equipment. Since measuring change over time is critically important to the objectives of the BLSA, comparability of testing equipment and procedures to maintain continuity of the research data is essential.

3. Generic Name of Product: Isokinetic dynamometer

4. Purchase Description: Isokinetic dynamometer, with dual dynamometers

5. Salient characteristics: NIA requires an isokinetic dynamometer system with two dynamometers to test both legs independently and simultaneously. Isokinetic dynamometers must provide constant velocity with accommodating resistance throughout a joint’s range of motion. The interface of the required system with the microprocessor kit must permit objective measurement of human muscle function related to torque, power and endurance. The system must also assure that observed changes in participant performance over time are due to changes in the individual’s ability and not due to inconsistent measurement capabilities of the device.
