Presentation
They often present with both weakness and sensory loss in a “ glove and stocking” fashion. [lecturio.com]
* About two thirds of patients present at 8-15 years of age, with a range of 2-40 years. * The most typical presentation is of weakness due to scapular-humeral-pelvic weakness that may be similar to the presentation of facioscapulohumeral dystrophy. [checkorphan.org]
Cardiac disease may be present in up to 33%. [emedicine.medscape.com]
This form of muscular dystrophy presents with weakness of the pelvic and shoulder girdle in childhood, with symptoms usually present by the age of 10 years. [sema4genomics.com]
Only the first and second heart sounds were present. The lung fields were clear and the liver was not palpable. [chs-journal.com]
Entire Body System
- Difficulty Climbing Stairs
LGMD1 patients may need to use walking aids, can have difficulties climbing stairs and lose the ability to walk. Creatine kinase (CK) levels can be normal to moderately elevated. [mdfgauteng.org]
Examples of this include trouble standing from a sitting position without using the arms, or difficulty climbing stairs. The weakness starts in childhood to young adulthood. [medlineplus.gov]

They may also experience difficulty running and climbing stairs. Respiratory problems have been reported with this form of LGMD, but heart abnormalities have not been. [rarediseases.org]
Symptoms that might be noticed first include frequent falls and difficulty climbing stairs, running and rising from the floor. [mda.org.au]
Musculoskeletal
- Proximal Muscle Weakness
In addition to proximal muscle weakness, there may or may not be: Distal muscle weakness. Muscle hypertrophy. Contractures. Involvement of the heart, respiratory muscles or tongue. (Facial weakness is not usual.) [patient.info]
The phenotype of LGMD typically includes predominant weakness in proximal limb muscles with sparing of the facial muscles. Distal muscle weakness may occur in severe cases or later in the disease course. [omicsonline.org]
Proximal muscles are the muscles that are closest to the center of the body such as the muscles of the shoulder, pelvis, and upper arms and legs. Muscle weakness may spread from the proximal muscles to affect distal muscles. [rarediseases.org]
Hypothyroid myopathy Patients can present with a proximal weakness. They may complain of fatigue or muscle pain and cramping. They have relaxation of the reflexes at an advanced stage of the disease. [lecturio.com]
[…] swallowing Caveolinopathy Approx. 5 years Mild to moderate proximal weakness Muscle cramping Enlargement of the calf muscles Some have no symptoms Bethlem myopathy Floppy muscles in infancy 2/3 of patents are wheelchair bound Proximal muscle weakness [encyclopedia.com]
- Lordosis
Affected individuals may also have an abnormally curved lower back ( lordosis ) or a spine that curves to the side ( scoliosis ). Some develop joint stiffness (contractures) that can restrict movement in their hips, knees, ankles, or elbows. [ghr.nlm.nih.gov]
Additional abnormalities that may develop in individuals with LGMD include abnormal side-to-side curvature of the spine (scoliosis), abnormal front-to-back curvature of the spine (lordosis), thickening and shortening of tissue that cause deformity and [rarediseases.org]
[…] strength in distal arms; LGMD2M FKTN / Fukutin Early childhood Very high Moderate Legs > arms; mild to moderate facial involvement LGMD2N POMT2 / protein O-mannosyl transferase 2 Early childhood High Slow Calf hypertrophy; scapular winging; skeletal lordosis [now.aapmr.org]
Children walk with waddle and exhibit lordosis. Cardiac involvement is known but not as common or prominent as in dystrophinopathies. [annalsofian.org]
Neurologic
- Gowers Sign
Mild to moderate elevated serum creatine kinase levels and positive Gowers sign are reported. [orpha.net]
Image : “Gower’s sign.” by William Richard Gowers (1845–1915) – Gowers WR. Clinical lecture on pseudohypertrophic muscular paralysis. Lancet 1879;ii,73-5. [lecturio.com]
Is there a finding (or history) of Gower's sign? This is seen in patients with proximal muscle weakness of the lower limb: when rising to stand, they use the hands as support, such that the hands 'climb up the legs'. [patient.info]
Treatment
Treatment: No treatment other than physical therapy is available. Prognosis: Most patients live into adulthood but progression is inevitable and all individuals eventually become totally disabled. [wohproject.org]
Treatment and management So far there are no specific treatments for LGMD2I, however managing the symptoms of the condition improves a person’s quality of life. Keeping mobile is important for all people affected with muscular dystrophy. [lgmd2i.com]
Early and prompt treatment and early surveillance is much better than waiting for problems to occur and then trying to deal with them. [treat-nmd.eu]
Supportive treatment can decrease the complications of the disease. The condition is managed based on the person's symptoms. [medlineplus.gov]

Prognosis
The symptoms are similar to DMD but often milder, and patients are less likely to have mental retardation and have a better prognosis (30-40 years instead of teens). [lecturio.com]
Prognosis and management, therefore, are not uniform across the subtypes of LGMD2. Nonetheless, early identification of complications and risk factors is crucial. [mdfgauteng.org]
Prognosis: Most patients live into adulthood but progression is inevitable and all individuals eventually become totally disabled. Ancillary treatments and support: Respiratory therapy is important when diaphragmatic weakness becomes prominent. [wohproject.org]
Contractures are common, in which case the disease needs to be differentiated from Emery-Dreifuss muscular dystrophy, Bethlem myopathy, and laminin-alpha2 deficiency Prognosis - Limb-girdle muscular dystrophy type 2A This depends upon the type. [checkorphan.org]
Prognosis The prognosis of LGMD varies tremendously. Most people with LGMD, however do not have severe symptoms and most experience a normal lifespan. Cardiac and respiratory difficulties can, however, decrease the lifespan. [encyclopedia.com]
Etiology
During the visit, the participant will be asked to fill out a couple of questionnaires asking questions about quality of life and activity limitations, as well as his/her understanding of their diagnosis with regards to etiology (or cause of their muscle [clinicaltrials.gov]

Pathophysiology

The pathophysiological role of calpain-3 is not exactly known. Immunohistochemical (IHC) analysis of calpainopathy is still not possible as there is no anti-calpain-3 antibody available that is compatible for IHC on muscle biopsy cryosections. [neurologyindia.com]
Multiple functions are described, but the pathophysiologic basis for LGMD1B is unknown. [emedicine.medscape.com]
Prevention
Some of the complications can be prevented with appropriate treatment. For example, a cardiac pacemaker or defibrillator can greatly reduce the risk for sudden death due to an abnormal heart rhythm. [medlineplus.gov]

This would entail close surveillance to recognize symptoms and to prevent detrimental sequelae. 2. [pubs.sciepub.com]
Prevention - Limb-girdle muscular dystrophy type 2A Not supplied. [checkorphan.org]
A physiotherapist can recommend stretches to keep joints supple and if necessary special splints (orthoses) to prevent muscle shortening (contractures) which are common in some types of LGMD. [mda.org.au]
