Research has shown that chiropractic therapy is effective when treating certain conditions, such as acute low back pain and neck pain, according to WebMD. Chiropractic therapy has also proven effective in the treatment of headaches.
Some evidence suggests conditions such as osteoarthritis and fibromyalgia may respond to the moderate pressure chiropractors use in their therapy, according to WebMD. However, it is important that chiropractors be well informed about an individual's medical history. People with osteoporosis, inflammatory arthritis and those who take blood thinners should not undergo spinal manipulation. In addition, cases have been reported where spinal manipulation has worsened slipped or herniated disks in the spine as well as caused stroke or injury to the spinal cord. However, such instances are rare.
