Advancements in healthcare, sports science, and rehabilitation have made accurate, individualized muscle function data essential to maximizing the capabilities and potential of athletes and patients. Isokinetic dynamometry (IKD) is a method of studying the biomechanical and physiological characteristics of the human musculoskeletal system. It is used with patients who have traumatic, orthopedic, or neurodegenerative diseases, as well as with athletes from various sports disciplines and healthy individuals. This methodology provides objective measurements of muscle strength and offers an accurate way to quantify strength. The equipment used for isokinetic testing typically includes an isokinetic dynamometer, which controls the speed of movement and measures the force exerted by the muscles throughout the entire range of motion. Unlike other strength tests, this technique controls the speed of movement while the resistance is adjusted to the effort of the subject. This allows for precise measurements of muscle strength, specifically peak torque (maximum force) and the endurance of the muscles involved in movement at the various joints of the musculoskeletal system. It measures the peak muscle strength, or torque, of a specific muscle group. Although torque is a criterion for strength, registering this parameter allows for the assessment of other time-based parameters, as well as work, power, and some indices. These indices are a criterion for balance in the work of antagonistic muscle groups in a given joint. This complex approach enables the evaluation of additional motor qualities, such as velocity and endurance. In static dynamometry, the speed of movement changes, but the weight, or resistance, that is overcome remains constant. In IKD, the angular velocity of movement in a given joint remains constant while the resistance overcome varies. The main advantage of this methodology is the constant speed and changing resistance, which is effort. This is provided by isokinetic dynamometer technology and allows torque to be measured as a strength criterion. Isokinetic loading is safer than traditional movement in kinesiotherapy. Technological advances and a greater focus on personalized healthcare and performance analysis have increased the importance of isokinetic testing in clinical and sports settings. As the fields of healthcare, sports science, and rehabilitation evolve, the need for accurate, individualized data on muscle function becomes critical. This methodology is an important tool for measuring muscle strength and performance in a safe, controlled, and objective environment. It helps prevent injury, facilitate rehabilitation, and optimize performance by providing comprehensive data on muscle function and balance.
