Different types and associated symptoms
Altogether there are nine types of muscular dystrophies. This cluster of genetically diverse disorders share clinical and pathological characteristics but differ in the age of onset, rate of progression, distribution of weakness, severity, inheritance pattern and molecular defect. It can be classified as follows:
|TYPE||AGE OF ONSET||SIGNS AND SYMPTOMS|
|Duchene||2 to 6 years||general muscle weakness and wasting; affects pelvis, upper arms, and upper legs; eventually involves all voluntary muscles|
|Becker||adolescence to early adulthood||identical to Duchenne, but less severe; progresses more slowly than Duchenne|
|Congenital||birth||general muscle weakness and possible joint deformities|
|Distal||40 to 60 years||weakness and wasting of muscles of the hands, forearms, and lower legs|
|Emery- dreifuss||Childhood to early teens||weakness and wasting of shoulder, upper arm, and shin muscles|
|Limb-Girdle||Late childhood to middle age||weakness and wasting, affecting shoulder girdle and pelvic girdle first|
|Facioscapulohumeral||Childhood to early adult age||facial muscle weakness and weakness with some wasting of shoulders and upper arms|
|Myotonic||20 to 40 years||weakness of all muscle groups accompanied by delayed relaxation of muscles after contraction; affects face, feet, hands, and neck first|
|Oculopharnyngeal||40 to 70 years||affect muscles of eyelids and throat causing weakening of throat muscles, which, in time, causes inability to swallow and emaciation from lack of food|
Causes of Muscular Dystrophy
When a group of disorders present at birth most likely due to a malfunction of a single gene, interferes with muscle veracity, the condition that develops is called muscular dystrophy. It is the result of inaccurate coding by the dystrophin gene that provides the protein code needed for muscle tissue formation.
Muscle weakness is generally caused when the cells that are used to sustain the muscles are no longer capable for their functionality. This furthermore leads to increasing weak points of the muscles and its disorder. Several symptoms of muscular dystrophy take place through the natural progression in the gene formation and these disorders are passed on from one age group to the other. Muscular dystrophy can be classified in these three ways:
- Autosomal dominant- This inheritance takes place when both parents pass a defective gene and a normal gene respectively to their child.
- Autosomal recessive- This inheritance means that both parents can transmit and transfer on the defective gene. It means that both the parents must hold one defective gene but remain unaffected by the disorder.
When a mother carries the affected gene on one of her two X chromosomes and passes it to her son, then the X-linked (or sex-linked) recessive inheritance takes place

STEM CELL THERAPY FOR MUSCULAR DYSTROPHY
There are advanced conceptions coming up for the treatment of MD. There are newer studies that have highlighted the possible possibility of stem cells to regenerate and repair the damaged muscle cells. Stem cells are those kinds of cells that develop at the early growth levels. This indicates they have the capacity to convert any type of body cells and undergo self regeneration.The capacity of adult muscle to undertake renewal is largely credited to a distinctive subpopulation of muscle cells, named as satellite cells. These cells are believed to be the chief cell type associated with skeletal muscle regeneration. Stem cell therapy is guaranteed to be the right a treatment form for MD to transmit progressive muscle proteins and restore the stem pool.
Objective radiological evidence of improvement in a muscular dystrophy
Our stem cell transplantation procedure does not only change the patients’ clinical symptoms, but also aims to restore and bring to a close further progression of muscle wasting that occurs in Muscular dystrophy. This has been demonstrated by the MRI-MSK reports of these patients.
Objective radiological improvements seen in a case of muscular dystrophy after stem cell therapy.
About Stem cell Therapy
- The mechanisms by which stem cells may function include
- Differentiation and cell fusions
- Secretion of cytokines
- Increase oxygen supply and contribute to vascularization in the damaged area.
The entire mechanisms contribute to tissue remodeling, decrease inflammation and prevent cell death. It contributes to the pattern of healthy cells altogether.The Adult stem cells transfers from several tissues consisting of the bone marrow, mesoderm that form the muscle cells. It ultimately restores the stem cell pool that helps in tissue renewal and repair.
Conventional treatment options
One of the most complicated disorders for treating is muscular dystrophy. Till date, there is no cure available for MD though its pathogenesis is well perceived. The conventional treatment options or methods of MD consist of exercise drugs that slow down or put an end to muscle dystrophy like anabolic steroids and supplementation.
Drug Treatment like the use of steroids have been verified to be an effective treatment to slow down the development of MD particularly DMD and in holding up the loss of independent ambulation, protecting the pulmonary functions and to even out the strength of the muscles.
The use of corticosteroids may help to improve myoblast proliferation and promote muscle regeneration. Then again using steroids will slow down the degradation of the muscles by alleviating lysosomal-bound proteases or muscle cell membranes. In the end, prednisone can decrease the damage done to the muscles in the course of its immunosuppressive and anti-inflammatory effects.
The key factor to rehabilitation management is the Rehabilitation Management of muscle extensibility and abnormal joint pain. The patients are guided to be more independent through physical therapy, occupational therapy, speech therapy and other recreational therapies.
Gene Therapy is an advanced form of therapeutic option. Through gene therapy, the patients are introduced to regularize the gene expression and the production of proteins. There are a number of approaches that are regulated for replacing the defective genes. Normally, in several gene therapies, the normal gene is put inside the genome to swap the abnormal gene that causes the disease. This procedure is done through viral vectors, Antisense- Induced Exon Skipping or Read through Stop Codon Strategies.
The NeuroGen outcome
Muscular dystrophy can wears out the emotional, physical and financial condition of the patients as well as their well wishers. Stem cell therapy has come up as a successful curative option after years of research and study.Presently, we have treated over 1428 patients of muscular dystrophy with 94% patients showing remarkable improvement.
After the successful therapy, our patients have shown a marked improvement such as increased trunk muscle strength, limb strength on manual muscle testing and balance. Additionally they have made improvement in ambulation, hand function, increase in stamina and better trunk balance. All these results in succession for the patients to lead a happier life.

Your most common questions answered
No muscular dystrophy is mainly a hereditary disorder and it is not at all contagious.
It is not always hereditary. Many researchers states that about 1/3 of all boys that suffers from Duchene/Beckers muscular dystrophy have no such family history.
It is often mentioned that there are several types of Muscular Dystrophy seen in people. Which is the most common type of muscular dystrophy?
The most common type of muscular dystrophy is Duchene. Beckers is the second most common MD and limb girdle muscular dystrophy is the third most common form.
The first symptom that you may notice in your child is they tend to start talking and walking late. But many conditions have different signs. Most parents may notice that their child is not running as fast as the other kids. Or the child may also get up from the ground, in a different way, using his hand for support and may have difficulty in climbing stairs.
Muscular dystrophy can be passed on from either of the parent through an affected gene.
In myotonic dystrophy, the carrier can be either one of the parents.
In limb girdle muscular dystrophy, the transmission could take place through a recessive gene. This means that both the parents are carrier, and they both transmit the disease.
Yes, there are 50% chances of your daughter being the carrier. To ascertain her case, opt for a genetic testing.
If there is a past record of previous child or sibling having this disease/condition then it is possible in an utero diagnosis of DMD. A Chorionic villus sampling or amniocentesis followed by a DNA testing (MLPA) can probably give some answers.
If there is a family history and a reasonable suspicion, then chances are there. But the symptoms cannot be detected unless the child reaches a certain age.
No there is no proven records to support that MD occurs only in children. For example facioscapulohumeral, myotonic and limb girdle muscular dystrophy begins later in life .They are slow in development and less severe than the childhood forms.
Few indications like facioscapulohumeral dystrophy, a weak smile or inability to whistle may indicate a beginning. Similarly, in Limb girdle MD weakness of shoulders and hip is seen and in case of Myotonic MD there is an apparent weakness of feet and hand.
Condition where the muscles get enlarged is known as pseudo hypertrophy. It can be replaced with fatty tissues.
The treatment option to help a child with MD to prolong his walking is to make a surgical release of tight or contracted muscle and help him on learning how to stand the very next day. The second option would be serial casting. This would help your child suffering from MD prolong his walking.
To keep the child ambulatory, regular sessions of physiotherapy and exercises would help. Helping them to stand with the help of push knee splints and high boots is very effective. Surgery becomes the best option when the muscles become very tight and are not stretchable at all.
A surgery can help set the joints straight. The best option to opt for when muscles become very tight and are not unstretchable is surgery alone. However, the amount of walking exercise would depend on the muscle strength of the lower limbs.
These therapies help in preventing contractures, keep muscles strong, help in transfer, improve efficiency of functional activities like standing, walking etc.
If exercises are done beyond the patients’ capability, it can lead to decline in their health. The patient should not get tired or fatigued. Ample time or rest has to be given between exercises.
Swimming is a good form of exercise for the child or patient of muscular dystrophy. Children should be advised to take up swimming lessons from a very early age. It helps to increase endurance, increases muscle strength and good work up for the respiratory and cardiac muscles.
The major cause of death is respiratory muscle weakness that leads to respiratory difficulty. As the muscles weaken, the child develops scoliosis or an abnormal, sideways curvature of the spine. The cough reflex gets into a weak position. Patient becomes more prone to chest infection and leads to difficulty in breathing.
Cardiac muscle weakness and cardiomyopathy are other major cause of death in muscular dystrophy patients.
The aim of stem cell therapy is to make the muscles stronger and slow down the deterioration of the muscles. If the patient is walking, the goal is to keep them walking. This indirectly could delay respiratory muscle weakness and prevent scoliosis. This could then prolong overall life expectancy, by reducing the chances of respiratory complications.
The biological task of stem cells is to repair and regenerate damaged cells. Stem cell therapy exploits this function by administering these cells in high concentrations directly in and around the damaged tissue, where they advance its self healing and repair.
No, there are no ethical concerns surrounding adult stem cell research and therapy. Ethical concerns are mostly occurs through the use of embryonic cells. Our therapy consists of using cells which are taken out from the patient’s own body and it is free from ethical concerns.
No, the treatment is not painful as the therapy is done under local anesthesia and a mild sedation. There is no major pain or discomfort during or after the procedure.
The whole therapy session is safe and till date none of our patients have shown any signs of neurological deterioration. In rare cases, side effects like headache for 3-4 days, neck or back pain, vomiting, mild rash or pain at the area of bone marrow aspirations may arise. Some unexpected medical complication can occur but that is just a possibility.
This may vary from patient to patient. Some patients makes a speedy improvement by 3-6 months while in some cases patients take several months or years together to heal. And there are some patients that recover even before their discharge
This will depend on the condition of the patient. If the patient shows signs of improvement after the first surgery then a second transplantation may be suggested by a team of experts. The second transplantation can transpire anytime between 3-6 months of the first therapy.
We will have to review the entire dose of medication before coming upon a decision. Generally we do allow the patients to continue their other medication. But it is better to consult a doctor beforehand..
Since this is a new therapy and not an existing one, it is difficult to say. It will depend on several factors like the age of patient, type of illness, duration of illness and extent of rehabilitation taken after the treatment.
