McKenzie Exercises. Pt for back and neck conditions involve stretching, strengthening, and some range of motion. These exercises start very gently, and then are progressed by a certified pt based upon patient response. All patients are different, so the exact exercises differ as does the progress. Use of heat, rubs, electrical devices and ultrasound is not a long-term answer. No pain no gain to a point.
Should not. If the person has not been exercising muscle soreness might occur. If pain is present it might worsen some but therapy should not cause significant pain.
