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.
For anywhere from six to 12 months after hip replacement surgery, pivoting or twisting on the involved leg should be avoided. You should also not cross the involved leg past the midline of the body nor turn the involved leg inward and you should not bend at the hip past 90 degrees.
