ATROPHY – wasting away of muscle due to lack of use. HYPERTROPHY – an increase in the size of the muscle cell.

STRAIN – tear in the muscle resulting from excessive use STRAIN – tear in the muscle resulting from excessive use. Bleeding inside the muscle can result in pain and swelling. Ice packs will help stop bleeding and reduce swelling.

MUSCLE SPASM (cramp) – sustained contraction of the muscle, usually because of overuse.

MYALGIA – muscle pain TENDINITIS – inflammation of a tendon Cause: overuse or disease S/S: pain, stiffness,weakness Diagnostic tests: hx, exam Treatment: RICE, PT, anti-inflammatory drugs, lasers, shock waves, ultrasound

(P)RICE R= REST I= ICE C= COMPRESSION E= ELEVATE

Tetanus “Lock Jaw” Cause: clostridium tetani bacteria S/S: progressive muscle spasm, paralysis, stiffness and pain, especially in jaw Diagnostic tests: physical exam, lab tests, hx of wound Treatment: wound hygiene, tetanus antitoxin, sedation, ventilator support, pain management

Muscular Dystrophy Cause: Genetic; carried on X chromosome; most common in boys; 1:3500 live male births S/S: muscle weakness in early stages; Later, significant muscle weakness including skeletal, cardiac, & smooth muscle Diagnostic Tests: physical exam, genetic testing, EMG, muscle biopsy Treatment: Palliative care

Myasthenia Gravis Cause: autoimmune attack at neuromuscular junction Most common in women under 40 and men over 50 S/S: progressive, flucuating muscle weakness, often starting with facial or eye muscles (MIND TO GROUND) Diagnostic Tests: Blood tests, EMG (electromyogram) Treatment: steroids, immunosuppressant drugs, plasma exchange, acetlycholinesterase inhibitors

Fibromyalgia Cause: unknown, but may be neurological S/S: chronic pain of at least 3 months, bilateral tenderness, fatigue, sleep disorders, depression, anxiety, exercise intolerance Mostly women (2% of population affected) Diagnostic Tests: Location of pain confined to “tender points” Treatment: antidepressants, pain relievers, exercise, anti-epileptic meds

Hernia Tear in the muscle wall that allows a structure (usually an organ) to protrude through it Umbilical or inguinal Can be dangerous if blood flow is restricted

Hernia cont. Cause: outpouching of intestines into the inguinal or umbilical region of the body S/S: visual bulging, pain, discomfort, possible adhesions, incarceration of intestinal loop, strangulation Diagnostic Tests: hx, physical exam Treatment: binding, surgical repair
