Under the watchful eyes of nurses and physiotherapy personnel, cardiac surgery patients will be looked after as they perform their exercises. This way the professionals will be alerted if the cardiac surgery patient is having troublesome symptoms. The exercises done are cardiovascular exercises like walking on a treadmill or riding a stationary bike. However, it may also occur in other jobs, such as on assembly lines. Tennis elbow can be an occupational injury as well, occurring any time one repetitively twists one's wrists.

There are many neurological conditions and physiotherapy can help many of them. Alzheimer's disease takes away the declining years of many older people. It is surprising to note that it can occur in people 40 years old or younger. ALS or Lou Gehrig's disease is a disease that robs the brain and spinal cord of the ability to move. Some of the possible problems are: lack of strength and endurance, limited range of motion, problems with sensation in the limbs, and troubles walking. Stroke rehabilitation will focus on the problems that the patient displays. A plan for treatment will be devised. Patients will learn to use limbs that the stroke has made temporarily useless.
