Total knee replacement (TKR) surgery can do wonders for an arthritic or damaged knee. But TKR is hard on the muscles around the knee. Surgery and the down time after surgery often cause these muscles to lose strength. Weakness is especially bad in the thigh muscles. Much of rehab after TKR involves strengthening the weak muscles around the knee. Electric muscle stimulation (EMS) can help muscles gain strength. It seems odd that simply passing an electrical current through a muscle can build it up, but it's true. EMS is sometimes used to regain strength after spine injuries. EMS has also been shown to help athletes build muscle. These authors tested using EMS in the thigh muscles after TKR. Fifteen patients were given EMS treatments after TKR. They were hooked up to EMS for four hours a day over six weeks. They also had the usual physical therapy. A second group of 15 patients received just the usual therapy. Both groups were checked for walking speed, walking effort, and knee function b...
Female athletes have many more injuries to the anterior cruciate ligament (ACL) of the knee than male athletes. Studies have shown that women college soccer and basketball players have two to four times as many ACL injuries as men. And among professional basketball players, women have 10 times more ACL injuries than men. ACL injuries are especially serious. They often require surgery and intense rehabilitation. And they force many injured athletes to give up their sports. No one is exactly sure why women suffer so many ACL injuries. It is known that the thigh muscles help stabilize the knee joint during start-and-stop sports like basketball and soccer. These researchers tested the muscle activity of male and female college athletes during exercise. They wanted to see if the thigh muscles worked differently when doing intense extension and flexion exercises. The results showed that the men's quadriceps muscles (in the front of the thigh) produced much more force than the women's. But t...
For the past 3 months i have been getting weird sensations in my head. Like my head is freezing. Also i get sharp stabbing pains on both sides of my head and at the back of my head.
