| Ringkasan≠ | Center of pressure (CoP) posturography measures postural stability by analyzing the movement of the body's center of pressure—the point where the total force of body weight is concentrated—during quiet stance or dynamic balance tasks. Formalized by Duarte and colleagues (2000), CoP analysis provides quantitative metrics of postural sway including sway area, path length, and velocity. These measurements reflect the integrated function of sensory systems (proprioception, vestibular, visual), central integration, and motor control. CoP posturography is widely used in neurology, vestibular medicine, rehabilitation, and sports science to detect balance deficits and monitor recovery. | Isokinetic dynamometry measures muscular strength and power production during movement at a constant, preset velocity. Pioneered by Hislop and Perrine (1967), isokinetic testing constrains limb velocity to a fixed speed (e.g., 60°/s or 120°/s), while the dynamometer adjusts resistance to match the subject's force production at each instant, accommodating all variations in force throughout the range of motion. This approach provides comprehensive strength profiling across a full joint range and allows comparison of concentric and eccentric contractions. Isokinetic testing is widely used in clinical rehabilitation, sports medicine, and research due to its objectivity and standardization. |
