Physical medicine and rehabilitation are a medical speciality that assists people in regaining body functions that have been lost due to illness or injury. This word is frequently used to refer to the entire medical team, rather than just the doctors. Many body functions, such as bowel and bladder problems, chewing and swallowing problems, problems thinking or reasoning, movement or mobility problems, speech and language impairments, can be addressed by rehabilitation. Although physical rehabilitation and physical therapy are sometimes used interchangeably, there are some major differences between the two. Physical rehabilitation is a broader word that encompasses a variety of professions, whereas physical therapy is a subset of physical rehabilitation. Individuals can return to their prior level of functioning with the support of a specialised physical therapy program, which encourages activities and lifestyle modifications that can help avoid additional injury and enhance overall health and well-being. Physical therapy is frequently recommended by primary care doctors at the first sign of a problem since it is considered a conservative approach to problem management.
