Dynamometry testing in spinal cord injury

Figure. Lafayette Manual Muscle Test System

Persons with spinal cord injury (SCI) demonstrate strength deficits that can limit their functional ability to perform activities of daily living. For a specific lesion level, performance of functional activities is related to the level of muscle strength. Consequently, in clinical practice, we need reliable measures of muscle strength to determine mobility capacity. Muscle-strength testing is used to document recovery or loss of motor function in SCI measure improvements in strength. Several methods are available for testing muscle strength, such as handheld, handgrip, and isokinetic dynamometers. We provide an overview of muscle-contraction definitions and testing methodologies and discuss the reliability of these testing methods.
