Shadow zone is an area where seismograph can not be detect earthquake after the seismic wave have passed through the earth. When earthquake strikes, seismic wave radiate out spherically from the earthquake's epicenter. At the angular distances of 104 degree to 140 degree from the earthquake focus, any direct P waves are not received.
Questions about bending over after Hip replacement. I just read in another thread a reminder of not bending over for 6 weeks after surgery. It has prompted this question. I guess I should ask the PT, but I'd also like input from folks who have been there. First, let me tell you about my job.
Your goal in the first 2-3 months after knee replacement is to maximize how far your knee can bend (flexion) and straighten (extension). Our goal is a range-of-motion (ROM) at least as good as your preoperative level and preferably 0-120 degrees.t is best not to take any long trips for three months after surgery. While not an absolute requirement, this advice is given because the risk of blood clots remains higher than normal for about 3 months after knee replacement, and prolonged sitting in a car or plane can add to this risk.
