The diagnosis of these disorders has presented a challenge to health care providers because of symptom overlap with other sensory and mo‑ tor disturbances with nocturnal predominance. [mayoclinic.pure.elsevier.com]

PATHOPHYSIOLOGY The pathophysiology of muscle cramps is still uncertain. [pmj.bmj.com]
As stated in the editorial, I do not believe that the use of quinine for muscle cramps should be banned. I concur with the conclusion of the systematic review with recommendations Dr. [cmaj.ca]
Selection criteria Inclusion criteria included randomised clinical trials, or observational studies reflecting NLC, muscle cramp, leg cramp, or rest cramp. [bmcfampract.biomedcentral.com]

With a normal CK, I think the major myopathies are less likely. [pediatrics.aappublications.org]
Neurologic
- Sleep Disturbance
NLC is characterized by abrupt muscle contraction, most often in the gastrocnemius or foot muscles, which occurs at night and may result in significant sleep disturbances. [mayoclinic.pure.elsevier.com]
This sleep-wake disorder is a frequent cause of sleep disturbance. Nocturnal leg cramps may delay sleep onset, wake the sleeper up, and delay the patient’s ability to fall back asleep, all of which results in lower sleep efficiency. [tuck.com]
Demographics, medical history, sleep disturbances, and cardiometabolic risk factors were evaluated using the 2005–2006 dataset. [journals.plos.org]
Leg cramps at night are defined as spasmodic, painful, involuntary, contraction of skeletal muscle that occur during the night when a person is sleeping, causing sleep disturbances. [physiotherapy-treatment.com]
- Involuntary Movements
Restless leg syndrome in particular can cause leg discomfort and involuntary movements. People with blockages in the arteries of the legs also might have pain and cramping, though these occur with movement rather than at rest in bed. [detroitnews.com]
Often the trigger is the involuntary movement of the foot downward from the ankle (plantarflexion). There is no easy way to avoid this from happening. [chicagohealthonline.com]
I should also point out that whenever involuntary muscle contraction is seen, the first step is to distinguish neuromuscular involuntary muscle contraction from involuntary movement disorders of the central nervous system (eg, chorea, myoclonic jerks, [pediatrics.aappublications.org]
Long-term treatment with levodopa can also lead to drug-induced dyskinesia, a condition characterized by exaggerated involuntary movements or uncontrolled muscle contractions. [mountsinai.org]

Diagnosing Iron Deficiency Anemia and Its Causes Because of the high association between RLS and iron deficiency, a test for low iron stores should be part of the diagnostic workup in RLS. [mountsinai.org]
Treatment
In patients with severe symptoms, a trial of 4–6 weeks’ treatment with quinine is probably still justified, but patients should be warned of the risks, and the efficacy of treatment should be monitored. [pmj.bmj.com]
Treatment should be interrupted at intervals of approximately three months in order to assess the need for further quinine treatment. [pharmaceutical-journal.com]
Is there an effective treatment? Unfortunately, treatment options are limited, but lifestyle modifications and gentle stretching may have some effect. Pharmacological treatment may be considered for people with frequent, severe leg cramps. [bpac.org.nz]
Treatment No current treatments for leg cramps have been proven both safe and effective. [aafp.org]
Patients should be monitored closely during the early stages of treatment for adverse effects. After an initial trial of 4 weeks, treatment should be stopped if there is no benefit. [gov.uk]
Prognosis
Outlook / Prognosis Can leg cramps be cured? Leg cramps don’t have a cure at this time. [my.clevelandclinic.org]

Her prognosis is guarded: Children with high-risk neuroblastoma treated with surgery, intensive induction chemotherapy, radiation, and bone marrow transplant have a 2-year event-free survival of ∼50%. [pediatrics.aappublications.org]
Etiology
Leg cramps (charley horses) are a common nocturnal symptom that can be difficult to manage because of uncertainties about etiology, appropriate diagnostic evaluation, and optimal treatment. [aafp.org]
In practice, physicians often have very little to offer in terms of either a clear explanation of the etiology or treatment options. [ahcmedia.com]
Potential medication etiologies include inhaled long-acting beta-agonists, statins, and diuretics[ 9 ]. Existing prevalence data suggest that 37–50% of older adults have such leg cramps[ 4, 5, 10 ]. [journals.plos.org]

Physiological methods may be useful for preventing cramps in some people, but there have been no controlled trials of these approaches. Quinine is moderately effective in preventing nocturnal leg cramps. [pmj.bmj.com]
