The Commander Muscle Tester adds an advanced dimension to research-proven-reliable dynamometer muscle testing without using a computer. Commander Muscle Tester objectively quantifies strength to identify areas of muscle weakness due to injury or disease. Commander Muscle Tester provides a wealth of information to assist you with planning treatment/rehab, evaluating progress, managing cases and rating impairment. Compact dynamometer fits easily in your hand. Records, stores and analyzes up to 40 bilateral tests with up to four repetitions per side. Calculates bilateral strength deficits for objective side-to-side comparisons. Calculates multiple repetition coefficient of variation (CV) for determining effort consistency. "Axis Compensation" circuitry guarantees 99% accuracy across entire test pad. "Quick-connect" system makes changing dynamometer test pads faster and easier.
