Intensive PT Helps Stroke Survivors Regain Arm Function

The key to regaining arm function after suffering a stroke is to spend more time in an intensive physical therapy program, according to a University of Florida Health study done in June 2015.

A release from the university notes that UF Health researcher Janis Daly Ph.D. said that after a stroke, the brain and body can start recovering immediately and can show improvement up to six months afterward. But this study focused on people who had persistent disability even a year or more after completing standard care. The study found that extensive physical therapy helped them recover motor function, even though they began the study treatment a year or more after stroke.

“The recovery was meaningful to patients in terms of physical function. Each person’s recovery was somewhat unique,” Daly. He is the paper’s lead author and a professor in the UF College of Medicine’s department of neurology. “Some had dramatic recovery, some had less. Some were able to perform functional tasks that they weren’t able to do before; some recovered the ability to move their arm so they could actually place the arm for functional tasks, for example into the sleeve of a sweater.’

Daly said the average change in function for patients who had been severely affected by their stroke was clinically significant for arm movements and for performing complex tasks. For instance, a man who had been unable to lift a spoon to his mouth can now feed himself.

Inability to combine regular motions — for example, flexing the shoulder and simultaneously extending the elbow while reaching for an object — can be one result of a stroke. The patient may concentrate on the reaching movement of the arm, but the normal neural pathways are interrupted, and the patient’s arm may flex inward toward the body instead of extending to reach for a glass of water or a fork, said Daly, also the director of the National Veterans Affairs Brain Rehabilitation Research Center of Excellence in Gainesville, Fla.

To help patients regain movements of the shoulders, arms and hands, which are crucial in many daily activities, researchers administered an intensive physical therapy program that included five hours of rehabilitation per day, five days per week, for 12 weeks to 39 study participants.

The researchers tested three different modes of rehabilitation. The first was motor learning rehabilitation. Daly compared motor learning rehabilitation after stroke to learning a new sport move, such as a beginner learning a tennis serve. In this type of rehabilitation, patients must concentrate on performing a movement as deliberately as possible, with as much normal movement as possible, and must practice the task repetitively.

“Think about a child learning to walk or to ride a bicycle,” Daly said. “They must practice over and over until they come close to perfection.”
