What is functional exercise?

In daily life, many people experience joint problems and seek various methods to address functional impairments. What, then, is functional exercise?

What is functional exercise?

Functional exercise is typically a rehabilitation method used following injury or surgery. Its purpose is to restore the pre-injury function of the body, joints, or affected area—hence the term “functional exercise.” It represents a holistic concept aimed at regaining normal physiological function. For instance, restoring the range of motion (ROM) in a joint—such as the elbow after trauma or non-surgical management—is essential. Following injury, the elbow often becomes stiff; therefore, restoring flexion and extension requires recovery of its ROM.

If the elbow has been immobilized with a cast for an extended period, its range of motion becomes significantly restricted. To restore this motion, passive movement is employed. Active movement follows passive movement. Active movement requires muscular strength; the sole distinction from passive movement is that muscles actively participate.

Passive movement can be performed using the contralateral hand, a physical therapist, or assistive devices, with the muscles fully relaxed. In contrast, active movement involves voluntary muscle contraction. Subsequently, both muscular strength and overall joint function are restored. All functional exercises follow a progressive approach. For example, the “anal lift exercise” involves consciously contracting and lifting the anal sphincter. This exercise can be performed anytime and anywhere. It strengthens the perianal musculature and may also help prevent premature decline in sexual function. We hope this explanation proves helpful!
