Transcript of Clinical Aspect of Muscular System

Clinical Aspects of Muscular System
Myopathy
A disorder of the muscles
Techniques for diagnosing:
Observation - look for muscle atrophy, deformities.
EMG
Enzyme studies - Creatine Kinase
Fibromyalgia Syndrome
Difficult-to-diagnose condition involving the muscles
Associated with:
Widespread muscle aches
Tenderness
Stiffness
Fatigue
Sleep disorder

Stress Injuries
Includes:
Accidental injuries
Repetitive strain injury (RSI)
Carpal Tunnel Syndrome
Involves the tendons of the finger flexor muscles and the nerves that supply the hand and fingers.
Hand numbness and weakness are caused by pressure on the median nerve as it passes through a tunnel formed by the carpal bones.
Polymyositis
Inflammation of skeletal muscle
Dysphagia
Cardiac problem
Cause unknown
Often associated with:
Rheumatoid arthritis
Lupus erythematosus
Muscular Dystrophy
Group of hereditary diseases - Duchenne
Involving progressive, non-inflammatory muscular dengeneration
Weakens & wastes away -> Replace by CT and fats
Co-exist with:
Cardiomyopathy - weakening of the heart muscle
Mental impairment
Common Upper Extremity Conditions
Rotator cuff (RTC) injury
Inflammation of RTC occur when people repeatedly perform overhead activities.
Amyotrophic Lateral Sclerosis
Progressive degeneration of motor neurons that leads to muscle atrophy
Signs:
Weakness
Cramping
Muscle twitching
Chronic Fatigue Syndrome
Myasthenia Gravis
Common Lower Extremity Conditions
Dermatomyositis
Symptoms:
Erythema
Dermaritis
Lilac-colored rash.
Diagnosis:
Muscle biopsy
Enzyme study
EMG
Treatment:
Exercise program
Medication
Persistence fatigue of unknown cause.
Associated with:
Impaired memory
Sore throat
Painful lymph nodes,
Muscle and joint pain
Headaches
Sleep problem
Immune disorders
Occurs after a viral infection
No treatment
An acquire autoimmune disease
Antibodies interfere with muscle stimulation
A progressive loss of muscle power
External eye muscles.
Other facial muscles.
Damage to soft tissue:
Muscles strain
Inflammation
Bursitis
Tearing of ligaments and tendons
Tendinistis:
Sign: pain, fatigue, ROM, weakness, stiffness, numbness.
Treatment: rest, elevation, ice packs, bracing, medications
Epicondylitis
Medial and lateral epicondyles of the distal humerus are attachment points for muscles
Inflammation of these tendons of origin causes pain.
Trigger Finger
A painful snapping, triggering, or locking of a finger as it is moved.
Caused by inflammation and swelling of the flexor tendon sheath at the metacarpophalangel joint that prevents the tendon from sliding back and forth.
Hamstring Strain - large muscle group in the posterior thigh that extends from hip to the knee and flexes the knee. Common in athletes who stop and start suddenly.
Shin-splint - pain in the leg's anterior tibial region from running on hard surfaces or overuse of the foot flexors.
Achilles tendinitis - large tendon that attaches the calf muscles to the heel and is used to plantar flex the foot at the ankle.
