Is muscular dystrophy and duchenne muscular dystrophy the same?
Muscular dystrophy is a group of genetic disorders characterized by muscle weakening and wasting, while Duchenne muscular dystrophy (DMD) is a specific type of muscular dystrophy caused by mutations in the dystrophin gene. DMD is the most common and severe form of muscular dystrophy, typically affecting boys and leading to progressive muscle weakness and loss of function.
Is Electrical stimulation contra indicated to Becker's muscular dystrophy?
Electrical stimulation is generally not contraindicated for Becker's muscular dystrophy, but caution is advised. Patients with this condition may have varying degrees of muscle function and response to stimulation, so individualized assessments are crucial. Consulting with a healthcare professional familiar with muscular dystrophies is essential to determine the appropriateness and safety of electrical stimulation for each patient.

Becker muscular dystrophy?
DefinitionBecker muscular dystrophy is an inherited disorder that involves slowly worsening muscle weakness of the legs and pelvis.Alternative NamesBenign pseudohypertrophic muscular dystrophy; Becker's dystrophyCauses, incidence, and risk factorsBecker muscular dystrophy is very similar to Duchenne muscular dystrophy, except that it gets worse at a much slower rate.The disorder is passed down through families (inherited). Having a family history of the condition raises your risk.Becker muscular dystrophy occurs in approximately 3 - 6 out of every 100,000 males. It is less common than Duchenne muscular dystrophy.SymptomsFemales rarely develop symptoms. Males will develop symptoms if they inherit the defective gene. Symptoms usually appear in boys at about age 12, but may begin later.Muscle weakness of the lower body, including the legs and pelvis area, slowly gets worse, causing:Difficulty walking that gets worse over time; by age 25-30 the person is usually unable to walkFrequent fallsDifficulty with running, hopping, and jumpingLoss of muscle massMuscle weakness in the arms, neck, and other areas is not as severe as in the lower body.Other symptoms may include:Breathing problemsCognitive problems (these do not get worse over time)FatigueLoss of balance and coordinationSigns and testsThe health care provider will do a nervous system (neurological) and muscle examination. A careful medical history is also important, because the pattern of symptom development resembles that of Duchenne's muscular dystrophy. However, Becker muscular dystrophy gets worse much more slowly.An exam may find:Abnormally developed bones, leading to deformities of the chest and back (scoliosis)Abnormality of heart muscle function (cardiomyopathy)Congestive heart failure or irregular heartbeat (arrhythmias) - rareMuscle deformities, including: Contractures of heels and legsAbnormal fat and connective tissue in calf musclesMuscle loss that begins in the legs and pelvis, then moves on to the muscles of the shoulders, neck, arms, and respiratory systemTests that may be done include:CPK blood testElectromyography (EMG) nerve testingMuscle biopsyor genetic blood testTreatmentThere is no known cure for Becker muscular dystrophy. The goal of treatment is to control symptoms to maximize the person's quality of life. Some doctors prescribe steroids to help keep a patient walking for as long as possible.Activity is encouraged. Inactivity (such as bed rest) can make the muscle disease worse. Physical therapy may be helpful to maintain muscle strength. Orthopedic appliances such as braces and wheelchairs may improve mobility and self-care.Genetic counseling may be recommended. Daughters of a man with Becker muscular dystrophy may carry the defective gene and could pass it onto their sons.Support GroupsYou can ease the stress of illness by joining a support group where members share common experiences and problems.See: Muscular dystrophy - support groupExpectations (prognosis)Becker muscular dystrophy leads to slowly worsening disability, although the degree of disability varies. Some men may need a wheelchair, while others may only need to use walking aids such as canes or braces.ComplicationsHeart-related complications such as cardiomyopathyLung failurePneumonia or other respiratoryinfectionsIncreasing and permanent disability, that leads to: Decreased ability to care for selfDecreased mobilityCalling your health care providerCall your health care provider if:Symptoms of Becker muscular dystrophy appearA person with Becker muscular dystrophy develops new symptoms (particularly feverwith cough or breathing difficulties)You are planning to start a family and you or other family members have been diagnosed with Becker muscular dystrophyPreventionGenetic counseling may be advised if there is a family history of Becker muscular dystrophy.ReferencesKliegman RM, Behrman RE, Jenson HB, Stanton BF.

What are the chances of getting muscular dystrophy from you r parents?
The chances of inheriting muscular dystrophy from your parents largely depend on the specific type of muscular dystrophy and the inheritance pattern associated with it. For instance, Duchenne and Becker muscular dystrophies are X-linked recessive disorders, meaning that mostly males are affected and females can be carriers. If a mother is a carrier, there is a 50% chance of passing the gene to her sons, who would be affected, and a 50% chance for daughters to be carriers. Other types may follow different inheritance patterns, so genetic counseling is often recommended for families with a history of the condition.
How does the genetic defect that causes Becker dystrophy work?
In Becker dystrophy, there is a less-active form of dystrophin (a protein) disrupting the gateway regulator, allowing some leakage of intracellular substances, leading to the myopathy.
How is Muscular Dystrophy tested for?
In the 1860s, descriptions of boys who grew progressively weaker, lost the ability to walk, and died at an early age became more prominent in medical journals. In the following ten years, French neurologist Guillaume Duchenne gave a comprehensive account of 13 boys with the most common and severe form of the disease (which now carries his name - Duchenne muscular dystrophy). It soon became evident that the disease had more than one form, and that these diseases affected males of all ages. Nine diseases including Duchenne, Becker, limb girdle, congenital, facioscapulohumeral, myotonic, oculopharyngeal, distal, and Emery-Dreifuss are always classified as muscular dystrophy.
What is the percentage of muscular dystrophy in males?
Prevalence of MD is higher in males. In the United States, Duchenne and Becker MD occur in approximately one in 3,300 boys. Overall incidence of MD is about 63 per one million people.
Facioscapulohumeral muscular dystrophy?
DefinitionFacioscapulohumeral muscular dystrophy is progressive muscle weakness and loss of muscle tissue.See also: Muscular dystrophyAlternative NamesLandouzy-Dejerine muscular dystrophyCauses, incidence, and risk factorsFacioscapulohumeral muscular dystrophy affects the upper body, unlike Duchenne muscular dystrophy and Becker muscular dystrophy, which affect the lower body.Facioscapulohumeral muscular dystrophy is a genetic disorder. It appears in both men and women and may develop in a child if either parent carries the gene for the disorder.Facioscapulohumeral muscular dystrophy affects approximately 5 out of 100,000 people. It affects men and women equally.SymptomsFacioscapulohumeral muscular dystrophy mainly affects the face, shoulder, and upper arm muscles. However, it can affect muscles around the pelvis, hips, and lower leg.Symptoms often do not appear until age 10 - 26, but it is not uncommon for symptoms to appear much later. In some cases, symptoms never develop.Symptoms are usually mild and very slowly become worse. Facial muscle weakness is common, and may include:Eyelid droopingInability to whistleDecreased facial expressionDepressed or angry facial expressionDifficulty pronouncing wordsShoulder muscle weakness causes deformities such as pronounced shoulder blades (scapular winging) and sloping shoulders. The person has difficulty raising the arms because of shoulder and arm muscle weakness.Weakness of the lower legs is possible as the disorder gets worse. The weakness can be severe enough to interfere with walking.Hearing loss and abnormal heart rhythms may occur, but are rare.Signs and testsA physical examination reveals weakness of the facial and shoulder muscles. High blood pressure may be noted but is usually mild. An eye exam may show changes in the blood vessels in the back of the eye.Tests that may be done include:Creatine kinasetest (may be slightly high)Electrocardiogram (EKG)EMG(electromyography)Genetic testing of chromosome 4Hearing testMuscle biopsy(may confirm the diagnosis)TreatmentThere is no known cure for facioscapulohumeral muscular dystrophy. Treatments are given to control symptoms and improve the person's quality of life. Activity is encouraged. Inactivity such as bedrest can make the muscle disease worse. Physical therapy may help maintain muscle strength.Expectations (prognosis)Disability is often minor. Lifespan is usually not affected.ComplicationsDecreased mobilityDecreased ability to care for selfDeformities of the face and shouldersHearing lossVision loss (rare)Calling your health care providerCall for an appointment with your health care provider if symptoms of this condition develop.Genetic counseling is recommended for couples with a family history of this condition who wish to have children.ReferencesKliegman RM, Behrman RE, Jenson HB, Stanton BF.
