Disorders of the Muscular Disorders of the Muscular SystemSystem
Tendonitis (tendin/o + -itis) Inflammation of the tendon caused by
excessive or repetitive use of a joint.
Myalgia (my/o + -algia) Muscle tenderness or pain
Myorrhexis (my/o + -rrhexis) Rupture of the muscle
Disorders of the Muscular Disorders of the Muscular SystemSystem
Dystaxia (dys- + tax/o + ia) Difficulty controlling voluntary movement
Contracture Abnormal shortening of the muscle tissue making the muscles resistant to stretching
Spasm (cramp) Sudden, involuntary contraction of a muscle or a
group of muscles
Disorders of the Muscular Disorders of the Muscular SystemSystem
Bradykinesia (brady + kinesi/o + ia) Extreme slowness in movement
Myasthenia Gravis Chronic autoimmune disease where there is
difficulty in the neuromuscular function causing episodes of extreme muscle weakness. Frequently affects the muscles that control eye movements, eyelids, chewing, swallowing, coughing and facial expression.
What kind of problems could the patient have??
Disorders of the Muscular Disorders of the Muscular SystemSystem
Muscular Dystrophy (dys + trophy) Group of disorders that cause muscle weakness
without affecting the nervous system.
Duchenne’s Muscular Dystrophy Form of muscular dystrophy that appears from 2-6
yrs of age and progresses slowly. Survival beyond late twenties is rare.
Disorders of the Muscular Disorders of the Muscular SystemSystem
Fibromyalgia (fibr/o + my/o + -algia) Chronic disorder of unknown cause. Causes
widespread aching pain, tender points, and fatigue. This syndrome does not cause joint
deformity, is not a progressive illness, and is not crippling.
Tender points Abnormal areas of soreness. Usually in predictable
locations at the base of the neck, along the spine, in front of the hip and elbow and behind the knee and shoulder.
Disorders of the Muscular Disorders of the Muscular SystemSystem
Rotator Cuff tendinitis Inflammation of the tendons of the rotator cuff. The
condition is often named for the cause (tennis shoulder, pitcher’s shoulder). See figure 4.12, p. 72
Carpal Tunnel Syndrome Occurs when the tendons passing through the
carpal tunnel are chronically overused and become inflamed and swollen. Swelling creates pressure on the nerve as it passes through the tunnel, causing pain, burning, and tingling in the fingers and hand. See figure 4.13, p. 73
Disorders of the Muscular Disorders of the Muscular SystemSystem
Sprain Injury to a joint (ex. - ankle, knee, wrist).
Frequently involves a stretched or torn ligament. Ligaments attach bone to bone.
Strain Injury to the body of a muscle or the attachment of
a tendon. Usually associated with overuse injuries.
Tendons attach muscle to bone. Shin Splint
Pain caused by muscle tearing away from the tibia. Usually caused by repeated stress to the lower leg.
Disorders of the Muscular Disorders of the Muscular SystemSystem
Paralysis Loss of sensation and voluntary muscle movement
due to disease or injury. Damage can be temporary or permanent.
Paraplegia Paralysis of both legs and the lower part of the
body. Spinal cord injury is below cervical vertebra
Disorders of the Muscular Disorders of the Muscular SystemSystem
Quadriplegia (quadr/i + -plegia) Paralysis of all four extremities.
Spinal cord injury involves the cervical vertebra. Above C5, respiration is affected.
Hemiplegia (hemi + -plegia) Total paralysis on one side of the body. Usually
associated with stroke or brain injury. Damage to one side of brain causes paralysis on
the opposite side of the body.
Diagnostic ProceduresDiagnostic Procedures Electromyography (electro- + my/o + graphy)
Records the strength of the muscle contractions as a result of electrical stimulation
Deep Tendon Reflexes Reflexes are tested with a reflex hammer to strike
the tendon. No response or an abnormal response may
indicate a disruption of the nerve supply to the involved muscles.
Treatments / ProceduresTreatments / Procedures
Medications Anti-inflammatory medications (Advil, Motrin) are
commonly used to relieve pain and reduce inflammation muscular problems.
Physical Therapy May be used to restore function through the use
of exercise, heat, massage, etc… to improve circulation, flexibility and muscle strength.
Career OpportunitiesCareer Opportunities
Physical Therapist Provide treatments to improve mobility and
prevent or limit permanent disability; can subspecialize in sports medicine, pediatrics, geriatrics, etc…
Massage Therapist Therapeutic touch to provide pain
relief and encourage healing.
Career OpportunitiesCareer Opportunities
Occupational Therapist Treats people with mental, physical,
developmental and emotional disabilities helping them to develop or maintain daily living skills.
Athletic Trainer Work to prevent and treat athletic injuries and provide rehabilitative services by
