Palpation at the surface of the body
Palpation at the surface of the body is commonly used to assess changes in heat and cold, hydration, and underlying pathological changes. A variety of techniques may be used for this purpose including scanning, drag technique, skin-on-fascia pushes, the pinch test and skin rolling.
The back of the hand is very sensitive to temperature variations. To detect these move your hand in fairly quick sweeping motions over the areas being assessed (this is called scanning). Heat sensors adapt quickly.
Heat may indicate inflammation, muscle spasm or hyperactivity or increased circulation. It may indicate an acute lesion.
Coolness may indicate reduced circulation, scar-tissue, or muscle flaccidity. It may indicate a chronic lesion.
Please note that someone who has recently exercised will have a higher body temperature than someone who has not. Also because your sense of temperature indicates the temperature of what is being sensed relative to your body temperature, if you have recently exercised their body temperature will feel cooler.
Very light surface stroking of the skin may be used to assess dryness or dampness. Your fingers should ‘drag’ on any areas of dampness. Areas of increased hydration have an increased thermal conductivity coefficient, which means that they will palpate as more hot or more cold than other areas.
Dampness/’drag’ may indicate an underlying myofascial trigger point, oedema or local sympathetic nervous system over-activation.
Dryness may indicate lack of circulation, or prolonged stress.
The time that the therapist is using scanning and/or drag technique is often a good time to observe the body. Does stroking over an area produce more goosebumps (pilimotor action) than other areas? Can you observe any changes in skin color, moles, skin growths and condition of the skin and fingernails.
Goose-bumps may indicate neuro-muscular hyperactivity in the muscles beneath the surface (e.g. trigger point)
- Pale skin may indicate lack of circulation
- Yellow skin may indicate liver dysfunction (e.g. jaundice)
- Blue skin may indicate lack of oxygen
- Redness may indicate fever, alcohol intake, trauma, or inflammation
- Hot redness or streaking may indicate possible infection, blood poisoning or thrombosis
- Vertical ridges may indicate nutritional difficulties
- Horizontal ridges may indicate stress caused by changes in circulation that affect nail growth
Moles or Lumps – A massage therapist should pay attention to their client’s moles, and should refer them to a doctor if any moles undergo changes, or if any lumps or skin growths develop.
Skin Condition (all of the following may indicate prolonged stress, medication side-effects or other pathological conditions)
- Skin split around the lips and nails
- Mouth sores
- Dry, scaly skin
- Excessively oily skin
Stretching the skin and skin rolling
The Pinch Test - If the skin does not spring back into it’s original position after a slight pinch, dehydration is indicated.
Loss of elasticity and resilience may indicate underlying myofascial adhesion, dehydration, myofascial trigger point activity, or reflex activity. The reflex activity may be due to segmental facilitation, or if it occurs in the area of visceral pain referral, the reflex activity may be due to visceral dysfunction. Where there is a loss of elasticity, skin may feel abnormally thick.
Lack of movement relative to the underlying tissues may indicate superficial connective tissue adhesions, or swelling.
Redness after massage or skin rolling can indicate a previous lack of circulation due to connective tissue changes, or may indicate the existence of a hyperactive muscle beneath the surface or a trigger point. This can be confirmed by eliciting tenderness with deeper pressure.
Palpation of superficial connective tissue
The superficial connective tissue separates the skin and the underlying muscle tissue, and allows the skin to glide over muscles during movement. This layer is palpated by increasing compressive pressure until the fibers of the underlying muscle are felt. If pressure is reduced so that the muscle cannot be felt the layer that you are engaging will be the superficial fascia. The tissue holds fluid, and should feel soft & springy like gelatin. If surface oedema is present it will be in the superficial fascia.
Oedema may indicate a lack of lymphatic return, or swelling secondary to an injury or inflammatory process. It may indicate an acute lesion.
