Resistance Exercise For Impaired Muscle Performance
Advantages and Disadvantages of Free Weights and Simple Weight-Pulley Systems (Gravitational) Pros (Advantages) • Exercises can be set up in many positions, such as supine, side-lying, or prone in bed or on a cart, sitting in a chair or on a bench, or standing. Many muscle groups in the extremities and trunk can be strengthened by simply reposi tioning the patient. • Free weights and simple weight-pulley systems typically are used for dynamic, non-weight-bearing exercises but also can be set up for isometric exercise and resisted weight-bearing activities. • A variety of movement patterns is possible, incorporating single plane or multiplanar motions. An exercise can be highly specific to one muscle or generalized to several muscle groups. Movement patterns that replicate functional activities can be resisted. • Free weights with interchangeable disks, such as a barbell, are versatile and can be used for patients with many different levels of strength, but they require patient or pers...
