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.
In general most surgeons prefer that you avoid certain positions of the hip that can increase your risk of dislocation of the hip for about 6 weeks following surgery. After 6 weeks, the soft tissues involved in the surgery have healed, and restrictions are often lifted â allowing more vigorous activity.
