Isokinetic exercise is a form of dynamic exercise in which the velocity of muscle shortening or lengthening and the angular limb velocity is predetermined and held constant by a rate-limiting device known as an isokinetic dynamometer. The term isokinetic refers to movement that occurs at an equal (constant) velocity. Unlike DCER exercise where a specific […]

The most common system of resistance training used with dynamic exercise against constant or variable resistance is progressive resistance exercise (PRE). A later section of the chapter, which covers systems of training using mechanical resistance, addresses PRE.
Dynamic constant external resistance (DCER) exercise is a form of resistance training where a limb moves through a ROM […]

The types of exercise selected for a resistance training program are contingent on many factors, including the cause and extent of primary and secondary impairments. Deficits in muscle performance, the stage of tissue healing, the condition of joints and their tolerance to compression and movement, the general abilities (physical and cognitive) of the patient, the […]

The mode of exercise in a resistance exercise program refers to the form of exercise, the type of muscle contraction that occurs, and the manner in which the exercise is carried out. For example, a patient may perform an exercise dynamically or statically or in a weight-bearing or non-weight-bearing position. Mode of exercise also encompasses […]

Just as correct alignment and effective stabilization are basic elements of manual muscle testing and dynamometry, they are also crucial in resistance exercise. To strengthen a specific muscle or muscle group effectively and avoid substitute motions, appropriate positioning of the body and alignment of a limb or body segment are essential. Substitute motions are compensatory […]

Understanding the relationships among pathology, impairments, functional limitations, and perceived disability is fundamental to the prevention or reduction of disability. The presence of functional limitations may or may not lead to loss of independence and result in disability. Take, for example, a relatively inactive person with long-standing osteoarthritis of the knees. The inability to get […]
