Physiotherapists in Watford treat many different conditions including the issues profiled below.

Physiotherapy Ultrasound

Ultrasound therapy is one of the large number of treatment techniques available to physiotherapists in treating the variety of conditions their patients present with. The frequencies used are in the range of 0.8 to 3.0 Megahertz, with a metal head used to generate the ultrasonic waves and ultrasound gel used between the skin and the head to facilitate transmission. A crystal in the head generates the waves by high frequency vibration and the waves pass through the gel and into the patient.s tissues to cause their effects. A local deep heating effect can be generated but this is typically not desirable so the machine head is kept moving and the settings may be set to pulsed mode so the beam of ultrasound is not continuous. This allows cooling and prevents heat build-up.

The effects of ultrasound can be many, including increasing the local blood flow, breaking down scar tissue or inhibiting its formation, a reduction in local swelling and inflammation. The physiotherapist will determine the size of the area to be treated and its tissue depth, choosing the size of machine head and the frequency and pulsed mode as appropriate. Higher doses and longer times are used for more chronic cases with the reverse for acute inflammatory conditions.

Physiotherapy and TENS

TENS or transcutaneous electrical nerve stimulation is a technique of treatment used for pain conditions of various kinds. A small, battery powered device is used to generate the signals which pass down wires to electrodes which adhere to the patient.s skin, with the frequency of the signals and their duration and repetition rates all adjustable. Electrodes, with four at least being best, can be placed around the areas of pain or along the specific nerve tracts which relate to the pain condition in a trial and error manner until the best technique for the patient is found.

TENS works on the idea of sending signals down the main sensory nerves in the painful area and when these signals reach the spinal cord they act as inhibitory factors on the transmission of pain in the spinal cord. The effect is similar to rubbing the damaged area when we bump ourselves hard on something. It reduces the pain and if we stop we will feel the pain come flooding back. Around 30 percent of people find TENS helpful for a variety of pain conditions. TENS is also used in labour as a non-drug alternative for pain relief in childbirth.
