CRAMPS, MUSCULAR:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
All patients should have a CBC, sedimentation rate, chemistry panel, electrolytes, and urinalysis. If there is associated diminished or absent peripheral pulses, then Doppler studies and arteriography should be done. If the cramps are acute in onset, time should not be wasted in performing these studies. Magnetic resonance angiography is an excellent alternative to invasive angiography, but it is expensive. If there is associated hypertension, then 24-hr urine aldosterone and plasma renin studies should be done. If there are positive Trousseau's and/or Chvostek's signs, a thorough investigation for hypoparathyroidism should be done. A single serum calcium and phosphorus and alkaline phosphatase is not enough, but repeated studies should be done. In addition, 24-hr urine collection for calcium and serum parathyroid hormones should be done. An endocrinologist should probably be consulted if there is any doubt about the existence of hypoparathyroidism or any of the other causes of hypocalcemia.

MUSCULAR ATROPHY:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
The basic workup includes a CBC, sedimentation rate, urinalysis, chemistry panel, ANA titer, serum protein electrophoresis, and VDRL test. Additional muscle enzymes may be ordered such as serum aldolase and CPK. A 24-hr urine collection for creatinine and creatine may be done.
At this point, it is best to consult a neurologist. He will probably order nerve conduction velocity studies and EMGs of the involved extremities. He also will be best qualified to determine the need for CT scans or MRIs of the brain or spine, as well as the particular study to order in each individual case. At times, spinal fluid analysis and muscle biopsies may be necessary to solve the problem. Also, a Tensilon test or acetylcholine receptor antibody titer may be ordered in suspected myasthenia gravis.

Muscle flaccidity [Muscle hypotonicity]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient isn’t in distress, ask about the onset and duration of muscle flaccidity and precipitating factors. Ask about associated symptoms, notably weakness, other muscle changes, and sensory loss or paresthesia.
Examine the affected muscles for atrophy, which indicates a chronic problem. Test muscle strength, and check deep tendon reflexes (DTRs) in all limbs.

Muscle weakness:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Begin by determining the location of the patient’s muscle weakness. Ask if he has difficulty with specific movements such as rising from a chair. Find out when he first noticed the weakness; ask him whether it worsens with exercise or as the day progresses. Also ask about related symptoms, especially muscle or joint pain, altered sensory function, and fatigue.
Obtain a medical history, noting especially chronic disease, such as hyperthyroidism; musculoskeletal or neurologic problems, including recent trauma; a family history of chronic muscle weakness, especially in males; and alcohol and drug use.
Focus your physical examination on evaluating muscle strength. Test all major muscles bilaterally. (See Testing muscle strength, pages 418 and 419.) When testing, make sure that the patient’s effort is constant; if it isn’t, suspect pain or other reluctance to make the effort. If the patient complains of pain, ease or discontinue testing and have him try the movements again. Remember that the patient’s dominant arm, hand, and leg are somewhat stronger than their nondominant counterparts. Besides testing individual muscle strength, test for range of motion (ROM) at all major joints (shoulder, elbow, wrist, hip, knee, and ankle). Also test sensory function in the involved areas, and test deep tendon reflexes (DTRs) bilaterally.

Muscle spasms [Muscle cramps]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient isn’t in distress, ask when the spasms began. Is there a particular activity that precipitates them? How long did they last? How painful were they? Did anything worsen or lessen the pain? Ask about other symptoms, such as weakness, sensory loss, or paresthesia.
Evaluate muscle strength and tone. Then, check all major muscle groups and note whether movements precipitate spasms. Test the presence and quality of all peripheral pulses, and examine the limbs for color and temperature changes. Test the capillary refill time (normal is less than 3 seconds), and inspect for edema, especially in the involved area. Observe for signs and symptoms of dehydration such as dry mucous membranes. Obtain a thorough drug and diet history. Ask the patient if he has had recent vomiting or diarrhea. Finally, test reflexes and sensory function in all extremities.

Abdominal rigidity [Abdominal muscle spasm, involuntary guarding]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient’s condition allows further assessment, take a brief history. Find out when the abdominal rigidity began. Is it associated with abdominal pain? If so, did the pain begin at the same time? Determine whether the abdominal rigidity is localized or generalized. Is it always present? Has its site changed or remained constant? Next, ask about aggravating or alleviating factors, such as position changes, coughing, vomiting, elimination, and walking.
Explore other signs and symptoms. Inspect the abdomen for peristaltic waves, which may be visible in very thin patients. Also, check for a visibly distended bowel loop. Next, auscultate bowel sounds. Perform light palpation to locate the rigidity and determine its severity. Avoid deep palpation, which may exacerbate abdominal pain. Finally, check for poor skin turgor and dry mucous membranes, which indicate dehydration.

Muscle spasticity [Muscle hypertonicity]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
When you detect spasticity, ask the patient about its onset, duration, and progression. What, if any, events precipitate its onset? Has he experienced other muscular changes or related symptoms? Does his medical history reveal an incidence of trauma or a degenerative or vascular disease?
Take the patient’s vital signs, and perform a complete neurologic examination. Test reflexes and evaluate motor and sensory function in all limbs. Evaluate muscles for wasting and contractures.
During your examination, keep in mind that generalized spasticity and trismus in a patient with a recent skin puncture or laceration indicates tetanus. If you suspect this rare disorder, look for signs of respiratory distress. Provide ventilatory support, if necessary, and monitor the patient closely.

Accessory muscle use:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient’s condition allows, examine him more closely. Ask him about the onset, duration, and severity of associated signs and symptoms, such as dyspnea, chest pain, cough, or fever.
Explore his medical history, focusing on respiratory disorders, such as infection or COPD. Ask about cardiac disorders, such as heart failure, which may lead to pulmonary edema; also inquire about neuromuscular disorders, such as amyotrophic lateral sclerosis, which may affect respiratory muscle function. Note a history of allergies or asthma. Because collagen vascular diseases can cause diffuse infiltrative lung disease, ask about such conditions as rheumatoid arthritis and lupus erythematosus.
Ask about recent trauma, especially to the spine or chest. Find out if the patient has recently undergone pulmonary function tests or received respiratory therapy. Ask about smoking and occupational exposure to chemical fumes or mineral dusts such as asbestos. Explore the family history for such disorders as cystic fibrosis and neurofibromatosis, which can cause diffuse infiltrative lung disease.
Perform a detailed chest examination, noting an abnormal respiratory rate, pattern, or depth. Assess the color, temperature, and turgor of the patient’s skin, and check for clubbing.

Muscle atrophy [Muscle wasting]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient when and where he first noticed the muscle wasting and how it has progressed. Also ask about associated signs and symptoms, such as weakness, pain, loss of sensation, and recent weight loss. Review the patient’s medical history for chronic illnesses; musculoskeletal or neurologic disorders, including trauma; and endocrine and metabolic disorders. Ask about his use of alcohol and drugs, particularly steroids.
Begin the physical examination by determining the location and extent of atrophy. Visually evaluate small and large muscles. Check all major muscle groups for size, tonicity, and strength. (See Testing muscle strength, pages 418 and 419.) Measure the circumference of all limbs, comparing sides. (See Measuring limb circumference.) Check for muscle contractures in all limbs by fully extending joints and noting pain or resistance. Complete the examination by palpating peripheral pulses for quality and rate, assessing sensory function in and around the atrophied area, and testing deep tendon reflexes (DTRs).

Muscle Cramps:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
Nocturnal leg cramps are common and easily recognized. They are due to muscle overuse, structural conditions such as flat feet, prolonged sitting, standing on hard floors, extracellular volume depletion, or electrolyte imbalance.
Generalized cramps suggest chronic disease of the motor neuron such as amyotrophic lateral sclerosis. Cramps recurrent and localized to one muscle group suggest nerve root disease. Myotonia is difficulty releasing a grip (handshake or doorknob) that improves with repeated contractions.
