Sam is an accountant who is especially busy during tax season. By the end of each day he complains of shoulder stiffness and tightness, as well as some upper back pain. What might be Sam's problem, and how could he prevent the discomfort?
Incorrect posture when sitting at a desk can result in kyphosis. Sam needs to practice good posture and/or invest in an ergonomic chair to help him maintain the proper thoracic vertebral curve.
