•  Ultrasound: It provides a deep heat to increase blood flow and make the cell wall more permeable which allows improved exchange across the cell membrane .The warmth generated by ultrasound can help relax muscles and ease pain.
  • TENS (Transcutaneous Electrical Nerve Stimulation): It stimulates your nerves via an electrical current through your skin. It assist you in modest short term pain relief. The use of a TENS machine helps in pain management .Pain is thought to be controlled by TENS in one of two ways
  • Sensory Level Stimulation – The Gate Control theory of pain means that the electrical input of the Tens machine interferes with the transmission of pain signals ,by blocking the neural “gate” through which the pain travels.
  •  Motor Level Stimulation – The goal of motor level stimulation is to cause the release of the body’s own opiate like substances to achieve pain relief.
  • Traction: it help to decrease back and neck pain and pain radiating into a leg or arm.Traction can relieve pressure on spinal nerve roots due to degenerative disc disease, herniated discs or spinal stenosis. lumbar traction is sometimes called spinal decompression therapy.
  • Laser: Laser therapy works by creating a concentrated beam of light radiation onto the area that requires treatment.This promotes the healing of the targeted tissue as well as reducing pain,inflammation and swelling.It can also help in the physical breakdown of thickened scar tissue after an operation.
  •  IFT ( Interferential therapy) :The principle of IFT is to pass two Medium Frequency Alternating Currents which are slightly out of phase ,through the tissues ,where the currents intersect to produce a low frequency effect .Main clinical applications are:

          -pain relief
          -muscle stimulation
          -increased local blood flow
          -reduction of edema
