After the first 48 hours, heat is used to increase blood circulation to the injured
site, promoting healing. Ultrasound may also be used to deliver heat deep into the
muscle tissue. Transcutaneous electrical nerve stimulation (TENS) is a method used
to reduce pain. The TENS unit employs electrical stimulation to override the pain
signals that are being sent to the brain. Therapeutic massage is helpful in stimulating
blood flow and reducing muscle tension. This should only be performed by someone
professionally trained in massage therapy. Incorrect massage can actually make the
condition worse.
Passive modalities prepare patients to move on to the active phase of physical therapy.
Exercise allows the patient to regain muscle flexibility and strength. At this point,
the patient will be doing the work, not the physical therapist. A stretching program
is initiated to regain flexibility and mobility in the spines muscles, ligaments
and tendons. Strengthening exercises are useful to stabilize the spine and help prevent
future episodes.
Physical therapy also encompasses learning proper body mechanics, so daily activities
can be performed without putting unnecessary stress on the spine. Proper techniques for
things such as sitting, standing and lifting are addressed.
