    Study Notes

    The Skin

    • The skin is the largest organ in the body, and it's also the most important in terms of manual therapy.
    • The skin serves six main functions:
      • Protection: Acts as a barrier to the invasion of organisms and bacteria, and contains melanin to protect against UV rays.
      • Temperature regulation: Helps regulate body temperature through heat absorption, sweat production, and vasodilation/vasoconstriction.
      • Excretion: Releases excess water and toxins through sweat glands.
      • Sensation: Contains specialized nerve endings to detect heat, cold, pressure, and touch.
      • Secretion: Produces sebum to lubricate hair shafts and protect the skin.
      • Formation of chemicals: Produces vitamin D and melanocyte-stimulating hormone (MSH).

    Structure of the Skin

    • The skin consists of three main layers:
      • Epidermis: The outermost layer, consisting of five sublayers (stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale).
      • Dermis: The middle layer, containing blood and lymphatic supply, collagen fibers, elastin, and various glands.
      • Subcutaneous tissue: The innermost layer, consisting of adipose tissue.

    Connection to the Nervous System

    • The skin is supplied by autonomic nerves, which innervate skin, blood, and glandular cells.
    • Sensory nerve endings send messages to the central nervous system for processing.
    • The skin is served by nerves from various parts of the spine, with each segment of the spine covering a specific area of the skin (dermatome).

    Pathologies of the Skin

    • Eczema: Characterized by red, itchy patches, and can be a local contraindication.
    • Psoriasis: Characterized by patchy lesions with a scaly appearance, and can be a local contraindication.
    • Contact dermatitis: Characterized by red, itchy patches, and can be a local contraindication.
    • Acne vulgaris: Characterized by blackheads, whiteheads, or inflamed red spots, and can be a local contraindication.
    • Impetigo: Characterized by fluid-filled blisters, and is a contraindication.
    • Folliculitis: Characterized by red pimples with a hair in the center, and is a local contraindication.
    • Boils: Characterized by infected hair follicles or oil glands, and is a local contraindication.
    • Viral conditions:
      • Ringworm: Characterized by a red, itchy, raised circle, and can be a local or global contraindication.
      • Athlete's foot: Characterized by itchy, flaky skin, and is a local contraindication.

    Pigmentation Disorders

    • Vitiligo: Characterized by patches of skin with no color or pigment, and is safe for massage therapy.
    • Albinism: Characterized by a total absence of pigmentation, and is safe for massage therapy.
    • Claasma: Characterized by dark skin discoloration or melasma, and is safe for massage therapy.
    • Ethyledes: Characterized by clusters of melanized cells, and is safe for massage therapy.
    • Freckles: Characterized by clusters of dark cells, and is safe for massage therapy.
    • Lentigo: Characterized by dark patches, and is safe for massage therapy.
    • Moles: Characterized by a collection of pigmented cells, and is safe for massage therapy unless changed or irregular.

    General Disorders of the Skin

    • Broken capillaries: Characterized by fine red lines, and is a local contraindication.
    • UV damage: Characterized by a thickened stratum corneum, and is safe for massage therapy.
    • Hives: Characterized by itchy, red lumps, and is a local contraindication.
    • Allergic reactions: Characterized by red, itchy patches, and is a contraindication.

    Skin Cancers

    • Basal cell carcinoma: Characterized by nodules or shallow ulcers, and is a local contraindication.
    • Squamous cell carcinoma: Characterized by a swelling type cancer, and is a local contraindication.
    • Malignant melanoma: Characterized by a mole that becomes larger, darker, and ulcerated, and is a local contraindication.

    Impact of Age on the Skin

    • As we age, the epidermis and dermis thin, and the skin becomes more delicate and less elastic.
    • The skin's immune function, vitamin D production, and glandular secretions decrease with age.
    • The skin's nerves do not change with age, so it's still important to communicate with clients about pressure and pain levels.### The Importance of Skin
    • Skin is the gateway to the client's nervous system, making it a crucial area to consider in treatment.
    • Touching a client's skin allows therapists to identify potential issues, such as inflammation, itching, flaking, and patching.

    Pathologies and Contraindications

    • It's essential to recognize pathologies on the skin to determine whether to treat a client, modify the treatment, or avoid it altogether.
    • Identifying contraindications, local or otherwise, is critical to ensure safe and effective treatment.
    • If in doubt, it's best to err on the side of caution, consult with the client, and seek medical clarity before proceeding.

    Hygiene and Safety

    • Hygiene is paramount, especially between clients, to prevent the transmission of bacterial and viral elements.
    • Age and skin quality are crucial factors in determining the appropriate techniques and pressures to use.

    Tailoring Techniques to Clients

    • Techniques, such as firm str or gliding transverse str, should be tailored to the client's individual skin type and needs.
    • Delicate older skin may require more gentle techniques, while other clients may benefit from firmer pressures.
    • Understanding the client's skin and adapting techniques accordingly is essential for delivering effective treatments.
