2 Palpation Hints Palpation means “to examine or explore by touching (an organ or area of the body), usually as a diagnostic aid.” Palpation is both an art and a skill. Palpation involves: Locating a structure Becoming aware of its characteristics Assessing its quality or condition so you can determine how to treat it

3 Palpation Hints In order to locate and feel the characteristics of body structures it is necessary to have a thorough knowledge of functional anatomy and experience this anatomy through mindful, hands-on practice.

4 A Full Sensory Experience
Palpation requires receptive hands and fingers, open eyes, listening ears, calm breath, and quiet mind.

5 Making Contact Your hands and fingers must be responsive and sensitive. Relaxed hands allow the body’s contours, temperatures, and structures to come more easily into your awareness. When palpating, you may want to close your eyes periodically to enhance your awareness.

6 Making Contact For greater sensitivity and stability, try laying one hand upon the other, using the top hand to create the necessary pressure, while the bottom hand remains relaxed. The bottom hand will stay receptive as the top hand directs movement and depth.

7 Making Contact Smaller structures can be located by using one or two fingertips.

8 Making Contact Larger structures are best palpated with the whole hand.

9 Making Contact By sculpting out all of the sides and edges, full hand contact helps to define the complete shape of a region or structure and also allows for a greater understanding of the interrelationships between structures.

10 Working Smart Vs. Working Hard
Take your time. Rushing will decrease your focus and awareness. Visualize what you are trying to access and verbalize this to your partner. Locate the structure on your own body first before trying to palpate it on your partner. Be patient.

11 Less Is More Often, if we cannot feel the structure we are trying to access, a common reaction is to press harder and deeper. Instead of pushing into the muscles and other tissues, try to invite the tissues into your hands.

12 Less Is More Gentle contact allows your hands to be sensitive.
Excessive pushing numbs the fingers and is unpleasant for your partner.

13 Palpating Deeper Structures
Even deep structures need to be accessed with mild palpation. The deeper you move into the body, the slower and softer your touch needs to be. Palpation at different levels of the body is not a question of pressure, but of intention.

14 Sensory Receptors An adult has over 600,000 sensory receptors in the skin – more nerve endings than in any other part of the body. The fingertips are one of the most sensitive areas, with up to 50,000 nerve endings every square inch. A single touch receptor can respond to a pressure of less than 1/1400 of an ounce – the weight of an average house fly.

15 Somatosensory Mapping

16 Homunculus

17 Rolling And Strumming When outlining the shape or edge of a bone, try rolling your fingers or thumb across, rather than along, its surface. Use the same procedure with the ropy fibers of muscle tissue. Like strumming the strings of a guitar, this method will help you ascertain the muscle’s fiber direction and tensile state.

18 Rolling And Strumming

19 Movement And Stillness
If the structure you are palpating is stationary, move your hands across it. If it is moving, stay still. When palpating an expectant mother’s abdomen, hoping to feel the fetus move, you keep your hand still.

20 Movement And Stillness
When you want to determine the fiber direction of a muscle or the shape of a bone, move your hands along its surface.

21 Practice, Practice, Practice
Practice on yourself. Practice on others.

22 Active Movement Active movement is performed by your partner.
She actively moves her body while you palpate or observe the movement. All active movements should be slow and smooth.

23 Passive Movement Passive movement is the opposite of active movement.
Your partner relaxes while you move her body.

24 Resisted Movement Resisted movement requires both of you to act.
Your partner attempts to perform an action against your gentle resistance. No movement should occur at the joint being assessed.

25 When In Doubt, Ask The Body
When palpating, you may be confused about various body structures and there whereabouts. If you want to know what a particular muscle or tendon is, palpate it and follow it in both directions to see where it leads you.

26 Three Principles Of Palpation
1. Move slowly. 2. Avoid using excessive pressure. 3. Focus your awareness on what you are feeling. Be present.

27 Textural Differences Different structures and tissues of the body will all have unique textures. Understanding these textural differences will help you determine which techniques to apply on a particular body part in your hands-on practice.

28 Skin The skin is the largest organ of the body.
The skin averages about 1/20 of an inch in thickness, with the eyelids having the thinnest skin – less than 1/500 of an inch. The skin is intimately connected with the superficial fascia and deeper tissues. Its texture, thickness and flexibility vary throughout the body.

29 Palpating Skin Palpate the skin on the back of your hand. Note the thin, delicate, and pliable quality. Turn your hand over and palpate the palmar surface. Here the skin has a tougher, thicker layering.

30 Skin

31 Bone Bones and bony landmarks (the hills, valleys, and bumps on the surface of bones) are easy to distinguish from other tissues because they have a solid feel. The bones shift along with the surrounding structures during movement. Muscles and tendons can feel very hard when a muscle contracts against resistance. The shape and rigidity of bones are constant, unlike muscles which transform from soft to hard.

32 Muscle Skeletal muscle is the voluntary contractile tissue that moves the skeleton. It is composed of muscle cells (fibers), layers of connective tissue (fascia), numerous nerves and blood vessels.

33 Muscle A layer of fascia (epimysium) encases the muscle “belly”, a deeper layer (perimysium) wraps along muscle fibers into bundles and, finally, each microscopic muscle fiber is bound in fascia (endomysium). The muscle’s layers of connective tissue merge at either end to form a strong tendon that attaches the muscle to a bone.

34 Muscle

35 Palpating Muscle Muscle has three specific physical characteristics which help to distinguish it from other tissues. Muscle tissue has a striated texture (similar to a plank of unsanded wood), whereas tendons have a smoother feel. The direction of the muscle fibers can be used to determine which muscle you are palpating. Muscle tissue can be in either a contracted or relaxed state. Relaxed muscle is soft and malleable. Contracted muscle has a firm, solid quality.

36 Palpating Muscle

37 Palpating Deeper Muscles
Sometimes the overlying muscle can be shifted to the side to palpate the deeper one. You can slowly compress your fingerpads beyond the superficial muscle into the deeper tissues (similar to palpating through your sweater, shirt, and skin to palpate the muscles in your arm.

38 Shapes of Muscle Bellies

39 Tendon Tendon attaches muscle to the periosteum (connective tissue) surrounding the bone. Tendons are dense connective tissue shaped into bundles of parallel collagen fibers. Each muscle has one or more tendons. Tendons come in many different shapes and sizes.

40 Tendon Some are long and thin while others are short and fat.
A broad flat tendon is called an aponeurosis. Tendons have a smooth resilient feel. Palpate from the belly of the muscle into the tendon. It may feel like a taut strand of cable.

41 Tendon

42 Ligament Ligaments connect bones together at a joint.
Their function is to strengthen and stabilize a joint. Ligaments are also made of dense connective tissue like tendons. The fibers in a ligament have a more uneven configuration than in tendons. Ligaments have a dense, taut feel.

43 Ligament

44 Tendon Vs. Ligament A tendon will become taut or slack depending upon whether it is shortened or lengthened if its muscle belly is contracted. Ligaments remain taut throughout all movements or states of contraction.

45 Fascia Fascia is a form of dense connective tissue.
It is a continuous sheet of fibrous membrane located beneath the skin and around the muscles and organs. It forms a three-dimensional matrix of connective tissue extending throughout the body from head to toe.

46 Fascia

47 Superficial and Deep Fascia
Superficial fascia is located deep to the skin and covers the entire body. It is a layering filled with adipose tissue, nerves, blood vessels, lymph vessels, and connective tissue. It can be very thin (back of the hand) or very thick (sole of the foot)

48 Superficial and Deep Fascia
Deep fascia surrounds muscle bellies, holding them together and separating them into functional groups. It also carries blood vessels and nerves. Portions penetrate the muscle belly and surround each muscle fiber.

49 Retinaculum A retinaculum is a structure that holds an organ or tissue in place. In relation to muscle tissue, it is a transverse thickening of the deep fascia which straps tendons down in a particular location or position.

50 Retinaculum Most retinacula are superficial and accessible.
It can be distinguished from its deeper tendons by its fiber direction. It will have transverse fibers than run perpendicular to the deeper tendons.

51 Retinaculum

52 Artery And Vein The pulse of the heart can be felt in an artery, but not on a vein. Arteries are often situated on the protected side of an appendage and buried deep to the musculature.

53 Artery And Vein Some veins can be palpated superficially.
We must be able to palpate arteries to obtain a pulse. We should avoid pressing on them when palpating muscles.

54 Bursa A bursa is a small, fluid filled sack that reduces friction between two structures. The bursa are primarily situated around joints. The body has approximately 600 bursae that cushion skin, tendons, ligaments, muscle, or organs from the hard surfaces of bones. They can be found between two muscles, two tendons, a tendon and a ligament, or a muscle and a ligament.

55 Bursa

56 Bursitis Bursitis is an inflammation of the bursa.
It causes tenderness in the area and crepitation (cracking and clicking sounds) of the joint. When inflamed, superficial bursa are easily palpable and sometimes visible. In their normal state, bursa are generally not palpable.

57 Nerve Nerve vessels are tube-shaped, mobile and tender when compressed. Although some sections of nerves and plexuses (bundles of nerves) can be accessed, they are best avoided. Compression or impingement of a nerve may create a sharp, shooting sensation locally or down the corresponding appendage.

58 Nerve

59 Lymph Node Lymph nodes collect lymphatic fluid from the lymphatic vessels. They are bean-shaped and may range in size from a tiny pea to an almond. They are located throughout the body.

60 Lymph Node Palpable groups of nodes are found in the body’s creases such as the groin, axilla, and neck. Healthy lymph nodes are roundish, slightly moveable, and non-tender. Glandular tissue is usually larger and has an irregular surface.

61 Lymph Node

62 Adipose Tissue Adipose (fatty) tissue is a form of loose connective tissue. The most palpable location of adipose tissue is in the subcutaneous layer of tissue between the skin and superficial fascia. This layer of adipose tissue varies in thickness throughout the body and may have different consistencies. Adipose tissue usually has a gelatinous consistency.
