Isokinetic is a word that explains a certain type of movement. You may have heard medical staff, especially those in sports medicine, use it. It refers to movement at a constant speed, regardless of the force used. It’s different from isotonic movements which refers to fixed forces that we exert on objects in our daily lives. For instance, when lifting a glass to drink, the weight of the object remains stable. However, the speed with which we lift the glass may vary each time.
Set up the Isokinetic devices to operate at a certain fixed speed for exercises or muscle tests. The device adjusts to the resistance automatically, so that the operator’s joints retain the same speed of movement. Take for example, an operator tries to deceive the device by applying more power. Then the device will automatically adjust its resistance to a higher level to adjust to the programmed speed.
Internationally, doctors and physiotherapists have been utilizing the Isokinetic devices for over 30 years for muscle training and therapy. These devices are considered to be the most effective tools for testing muscle efficiency. They are the preferred tool for training and rehabilitating muscles of patients who have undergone joint surgery, especially knee surgery. Therefore, the Sport and Orthopaedic Center at Samitivej Sukhumvit Hospital has introduced the use of isokinetic devices. Doctors will use it to:
