Nocturnal Leg Cramp

Nocturnal Leg Cramps


Presentation

  • 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]
  • […] heat Polysomnography (sleep recording) shows: Increased electromyographic (muscle) activity in the affected leg and associated awakening No evidence of any underlying medical disorder that could account for the sensation Other sleep disorders may be present[web.stanford.edu]
  • Figure 1 presents the selection of the studies through the review process.[bmcfampract.biomedcentral.com]
  • An elevated HbA1c was also associated with frequent NLC, as were diabetes and fasting glucose (but not insulin), and the former variable was present after overall health was removed from the stepwise regression.[journals.plos.org]
Non-Alcoholic Cirrhosis

Increased Susceptibility to Infections
  • Immune function can be affected increasing susceptibility to infection. When you can’t get a good night’s sleep on a regular basis there are even more serious consequences.[peoplespharmacy.com]
Jaundice
  • […] leg syndrome or periodic limb movement disorder Numbness, tingling and "electric" pain, with secondary cramps; unrelated to sleep or exercise Peripheral neuropathy Cramps accompanied by metabolic signs or symptoms Kidney failure Cramps accompanied by jaundice[bpac.org.nz]

  • With a normal CK, I think the major myopathies are less likely.[pediatrics.aappublications.org]

Panic Attacks
  • There was no observed seasonality for search terms for back pain, kidney stones, migraines, acne or panic attacks.[sciencedaily.com]
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]
  • Article First Online: 09 January 2010 Abstract Nocturnal leg cramps are a frequent cause of sleep disturbance among the general population, especially among the elderly.[link.springer.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]
Reduced Consciousness

  • In this article, we review the epidemiology, pathophysiology, and risk factors and discuss the salient features of the diagnosis and workup.[link.springer.com]
  • A basic laboratory workup should include sodium, potassium, calcium, magnesium, glucose, renal function, creatine phosphokinase (CPK) and thyroid function tests.[angiologist.com]
  • While the team was discussing the need for additional diagnostic workup, additional laboratory results returned.[pediatrics.aappublications.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]
Rhythmic Slowing
  • Periodic limb movement disorder is a nonpainful, repetitive, rhythmic, slow dorsiflexion of the toes, knees, and hips during sleep. The movements last for seconds and recur at intervals of seconds to about one minute.[aafp.org]

Treatment

  • 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]
  • 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 should be interrupted at intervals of approximately three months in order to assess the need for further quinine treatment.[pharmaceutical-journal.com]
  • Treatment Talk with your doctor about the best plan for you. This may include treatment for any underlying causes of the nocturnal leg cramps.[cancercarewny.com]
  • Among the non-drug treatments, what appears to be a folk remedy (soap in the bed) is #1, followed by an array of approaches that seems to be endorsed or accepted by most of the treatment guidelines that exist: stretching, mobilization, heat and massage[sciencebasedmedicine.org]

Prognosis

  • Source: iStock What is the prognosis of recurrent muscle cramps? Although cramps can be a great nuisance, they are a benign condition.[medicinenet.com]
  • 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

  • In practice, physicians often have very little to offer in terms of either a clear explanation of the etiology or treatment options.[ahcmedia.com]
  • 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]
  • 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]

  • Pathophysiology and Causes of Nocturnal Leg Cramps The exact mechanism of leg cramps is not known. It is suggested that lower motor neurons with hyperactive, high-frequency, involuntary nerve discharge are responsible for these cramps.[medcaretips.com]
  • PATHOPHYSIOLOGY The pathophysiology of muscle cramps is still uncertain.[pmj.bmj.com]
