o Muscle atrophy or weakness in rheumatoid arthritis.
• Swelling. Palpable swelling may involve (1) the synovial membrane, which can feel boggy or doughy; (2) effusion
from excess synovial fluid within the joint space; or (3) soft-tissue structures such as bursae, tendons, and tendon
sheaths.
o Palpable bogginess or doughiness of the synovial membrane indicates synovitis, which is often
accompanied by effusion. Palpable joint fluid in effusion, tenderness over the tendon sheaths in tendinitis
• Warmth. Use the backs of your fingers to compare the involved joint with its unaffected contralateral joint, or with
nearby tissues if both joints are involved. (Felt in arthritis, tendinitis, bursitis, and osteomyelitis)
• Tenderness. Try to identify the specific anatomic structure that is tender. Trauma may also cause tenderness. o
Tenderness and warmth over a thickened synovium suggest arthritis or infection.
• Redness. Redness of the overlying o Redness over a tender joint suggests septic or gouty arthritis, or possible
rheumatoid arthritis.
Muscle Bulk
• Begin the exam by inspecting the size and contours of muscles. Do the muscles look flat or concave, suggesting
atrophy? If so, is the process unilateral or bilateral? Is it proximal or distal?
o Muscular atrophy refers to a loss of muscle bulk, or wasting. It results from diseases of the peripheral
nervous system such as diabetic neuropathy, as well as diseases of the muscles themselves.
Hypertrophy is an increase in bulk with proportionate strength, whereas increased bulk with diminished
strength is called pseudohypertrophy (seen in the Duchenne form of musculardystrophy).
• When looking for atrophy, pay particular attention to the hands, shoulders, and thighs. The thenar and hypothenar
eminences should be full and convex, and the spaces between the metacarpals, where the dorsal interosseous
muscles lie, should be full or only slightly depressed. Atrophy of hand muscles may occur with normal aging,
however, as shown on the right below. Be alert for fasciculations in atrophic muscles. If absent tap on the muscle
with a reflex hammer to stimulate them.
o Flattening of the thenar and hypothenar eminences and furrowing between the metacarpals suggest
atrophy. Localized atrophy of the thenar and hypothenar eminences in median and ulnar nerve damage,
respectively.
o Other causes of muscular atrophy include motor neuron diseases, any disease that affects the peripheral
motor system projecting from the spinal cord, rheumatoid arthritis, and protein-calorie malnutrition.
Muscle Tone.
• When a normal muscle with an intact nerve supply is relaxed voluntarily, it maintains a slight residual tension
known as muscle tone. This can be assessed best by feeling the muscle’s resistance to passive stretch. Persuade
the patient to relax. Take one hand with yours and, while supporting the elbow, flex and extend the patient’s
fingers, wrist, and elbow, and put the shoulder through a moderate range of motion. With practice, these actions
can be combined into a single smooth movement. On each side, note muscle tone—the resistance offered to your
movements. Tense patients may show increased resistance. The feel of normal resistance is learned with
repeated practice.
o Decreased resistance suggests disease of the peripheral nervous system, cerebellar disease, or the
acute stages of spinal cord injury.
• If you suspect decreased resistance, hold the forearm and shake the hand loosely back and forth. Normally the
hand moves back and forth freely but is not completely floppy.
o Marked floppiness indicates muscle hypotonia or flaccidity, usually from a disorder of the peripheral motor
system.
• If resistance is increased, determine whether it varies as you move the limb or whether it persists throughout the
range of movement and in both directions, for example, during both flexion and extension. Feel for any jerkiness
in the resistance.
o Spasticity is increased resistance that worsens at the extremes of range. Spasticity, seen in central
corticospinal tract diseases, is rate dependent, increasing with rapid movement. Rigidity is increased
resistance throughout the range of movement and in both directions (not rate dependent). To
assess muscle tone in the legs, support the patient’s thigh with one hand, grasp the foot with the other,
and

flex and extend the patient’s knee and ankle on each side. Note the resistance to your movements.
Muscle Strength.
• People vary widely in their strength, and the assessment should allow for such variables as age, sex, and
muscular training. A person’s dominant side is usually slightly stronger than the other side. Keep this difference in
mind when comparing sides.
o Impaired strength is called weakness, or paresis. Absence of strength is called paralysis, or plegia.
Hemiparesis refers to weakness of one half of the body; hemiplegia to paralysis of one half of the body.
Paraplegia means paralysis of the legs; quadriplegia, paralysis of all four limbs.
• Test muscle strength by asking the patient to move actively against your resistance or to resist your movement.
Remember that a muscle is strongest when shortest, and weakest when longest.
• If the muscles are too weak to overcome resistance, test them against gravity alone or with gravity eliminated.
When the forearm rests in a pronated position, for example, dorsiflexion at the wrist can be tested against gravity
alone. When the forearm is midway between pronation and supination, extension at the wrist can be tested with
gravity eliminated. Finally, if the patient fails to move the body part, watch or feel for weak muscular contraction.
Multiple Choice
1. Which of the following types of arthritis usually has high uric acid serum levels in the blood?
a. Gouty arthritis
b. Rheumatoid arthritis
c. Osteoarthritis
d. Any of the above
ANSWER: A
RATIONALE: Uric acid builds up in the joints and tissues of patients with this illness, causing pain, swelling, and
discoloration. The toe joints, ankles, and knees are the most typically affected by gout.
ANSWER: C
3 of 6
RATIONALE: Recent infection is the cause of rheumatoid arthritis in a patient, which such infection with certain
viruses and bacteria that may trigger the disease.
ANSWER: D
RATIONALE: Both arthritis and infection indicate the tenderness or warmth above a thickened synovium.
4. Which of the following conditions have progressive loss of cartilage within the joints causing damage to underlying
bone, and formation of new bone at the margins of the cartilage?
a. Rheumatoid arthritis
b. Osteoarthritis
c. Gouty arthritis
d. Fibromyalgia syndrome
ANSWER: B

9. When assessing for the muscle strength of a post-stroke patient, the nurse has noticed paralysis in the right half
of the body. The nurse must note this on her chart as
a. Paraplegia
b. Quadriplegia
c. Hemiplegia
d. Hemiparesis
ANSWER: C
RATIONALE: The nurse must note hemiplegia on the chart, because damage to the neurological system causes
hemiplegia, which affects the muscles on the right side of the body.

detectable flicker or trace of contraction from the muscle. She must grade the patient’s muscle strength as
a. 0
b. 1
c. 2
d. 3
ANSWER: B
RATIONALE: The nurse must grade the patient’s muscle strength as 1, since it barely detectable flicker or trace of
contraction from the muscle.
