Over 200,000 knee replacements are done every year in the United States. People receiving new knee joints average 68 years old. A potential problem after this operation is weakness of the thigh muscles (called the quadriceps femoris ). This weakness often persists even with exercise. Loss of strength before surgery is usually caused by aging and arthritis. And if these don't spell trouble, the operation itself affects the muscles even more. Leg weakness can keep a person from getting back to daily activities such as walking, climbing stairs, standing up from a low chair, or getting in and out of a car. Exercise is used to build up the muscle after knee surgery, but there is often less strength compared to the other leg. In the case of one 66-year-old man, electrical stimulation was combined with exercise to increase the force of the quadriceps muscles. Electrical stimulation (ES) is used most often by a physical therapist to retrain and build up muscles. ES works by sending an electric c...
Knee replacements are common among older adults with painful joint arthritis. It has been assumed that the decrease in pain after recovery from joint replacement surgery translates into improved motion, strength, and function. But physical therapists working with these patients have noticed problems with climbing stairs and a slower walking speed long after recovery and rehab. Rehabilitation researchers around the world have confirmed these observations. Measures of muscle strength, CT scans showing muscle cross section, walking speed, and time to complete stairs have provided quantifiable evidence to back up this finding. Now similar results have been observed in patients who have a unilateral knee replacement (UKR). Unilateral knee replacement refers to an implant for half of the joint. Usually the medial side of the knee (closest to the other leg) is replaced most often because that's where most of the wear and tear occurs in many patients. In this study, physical therapists from Fin...
Back pain - nonspecific
The majority of nonspecific back pain is probably caused by muscle strain. This usually responds to 2-5 days of rest and pain medications (such as nonsteroidal anti-inflammatory agents -- ibuprofen, naproxen, aspirin, etc.), followed by gradual return to activities. Medications may be needed to reduce muscle spasms.
Physical therapy is often prescribed to instruct the patient on proper body mechanics (such as good posture and lifting correctly) and to improve strength and flexibility in the spine, abdomen, and legs.
Surgery is not useful for the treatment of nonspecific back pain.
Most cases of nonspecific back pain resolve on their own or respond to treatment. It is helpful to sleep on a firm mattress, with a board under the mattress, or even on the floor. Heat or ice applied to the affected area may provide some relief.
