Everyone who goes into surgery for a total knee replacement (TKR) knows the leg is weak from pain and disuse. When and how does muscle strength come back after the operation? Studies show that many patients have weakness and loss of function that can go on for years. Electrical stimulation of the muscles improves strength in young adults. What effect will it have on older adults after a TKR? Physical therapists enrolled patients who were having both knees replaced at the same time in a study of electrical stimulation. Having subjects with both knees replaced gave researchers a chance to use electrical stimulation on only one side. Results were then compared to the patients' own knee that did not get electrical stimulation. Two groups were formed in this study. One group received the same exercises for both legs. The other group received neuromuscular electrical stimulation (NMES). The NMES group did exercise on one side and exercise along with NMES on the weaker leg. Everyone started th...
Facts are simple things, indisputable conclusions that are as solid as Gibraltar. The myriad bits of information that establish facts may leave us scratching our heads, but the end result is bulletproof.
I still shudder every time I recall algebra class. I could have very well scratched my head bald had simple confusion not been replaced by a comfortable sort of stupor. Still in all, those formulas on the blackboard produced an indisputable Gibraltar time and again. At least that is what those students who actually understood what was going on told me.
Algebra aside, facts are simple things. Having said that, here is a fact: obesity is bad for you . Simple, right? As a matter of fact, obesity can be fatal for a number of reasons. For instance, obesity can cause blood clots . What Are Blood Clots? Blood clots are normally useful. Blood clots help the body repair injured blood vessels by sending platelets to the injured area where they form a plug. The platelets then release...
Treatment - back strain
A common misconception about back pain is that you need to rest and avoid activity for a long time. In fact, bed rest is NOT recommended. If you have no sign of a serious cause for your back pain (such as loss of bowel or bladder control, weakness, weight loss, or fever), then you should stay as active as possible. Here are some tips for how to handle back pain and activity early on:
Stop normal physical activity only for the first few days. This helps calm your symptoms and reduce any swelling (inflammation) in the area of the pain.
Apply heat or ice to the painful area. One good method is to use ice for the first 48 to 72 hours, then use heat after that.
Take over-the-counter pain relievers such as ibuprofen (Advil, Motrin IB) or acetaminophen (Tylenol).
Sleep in a curled-up, fetal position with a pillow between your legs. If you usually sleep on your back, place ...
