Patients who have had a neurological illness, such as a stroke, often lose
their ability to control the way they move their arms, legs or trunk. They
may have tremors, spasms or lose the ability to know where their arm or leg
is in space. Physical therapists are trained to use different techniques to
help patients with these problems regain the use of their limbs. These
techniques may include weight-bearing exercises and moving or positioning
limbs in specific patterns. Therapists may also use devices, such as slings
or splints, to help with proper limb positioning.
