Underinsurance based rehabilitation you can only attack the “site” of pain not the “source” of pain. They must conduct their treatments this way because insurance companies will not pay for interventions anywhere else. This may create temporary relief but is not a long-term solution. For example, if you go to physical therapy for your lower back they can ONLY focus treatments at the lower back when the real reason why your back hurts is your hips, ankles, or another region of the body that is not doing what it needs to.
Moreover, they must focus on having a high volume of patients due to the poor reimbursements from insurance companies. This means a crowded room, divided attention, and a 15 to a 20-minute maximum of hands-on intervention. This is not enough time to eliminate your pain and get you back to what you love.
