Ehlers-Danlos And Muscle Spasticity: What's The Connection?

does ehlers danlos cause muscle spasticity

Ehlers-Danlos syndrome (EDS) is a group of disorders that affect connective tissues supporting the skin, bones, blood vessels, and other organs and tissues. The various forms of EDS have been classified in different ways, with 13 types of EDS described in the 2017 classification. EDS patients commonly experience muscle pain, muscle cramps, and muscle weakness. In addition, movement disorders such as uncontrolled muscle contractions, tremor, fidgeting/dancing movements, twitches, and jerking are reported in EDS patients. While there is no established treatment for these disorders in EDS patients, pain medication and physiotherapy are often used to manage symptoms and prevent muscle spasms.

Characteristics Values
Muscle spasms Caused wholly or partly by EDS, depending on its type

Muscle spasms and dysfunction in EDS

Muscle spasms and dysfunction are common in people with Ehlers-Danlos Syndrome (EDS). EDS is a group of heritable connective tissue disorders featuring joint hypermobility, dermal dysplasia, and vascular and internal organ fragility. The neurological manifestations of EDS include musculoskeletal pain, fatigue, headaches, muscle weakness, and paresthesias.

The majority of EDS patients take pain medication, and many also receive physiotherapy to avoid muscle spasms. According to one research paper, two-thirds of patients reported that this treatment was beneficial. There is growing evidence that a multidisciplinary approach to care is effective. Physiotherapy, cognitive behavioural therapy, and group therapy, followed by individual home exercises and weekly coaching from a physiotherapist, have been shown to improve patients' performance in everyday tasks, increase muscle strength and endurance, and decrease the fear of movement.

Massage and myofascial release treatment are also frequently sought by persons experiencing pain and tiredness due to muscle stiffness. These methods can be obtained from a practitioner or performed at home using balls, rollers, sticks, and other similar tools.

In addition to muscle spasms, EDS patients may also experience uncontrolled muscle contractions, tremors, twitches, and jerking. These movement disorders may cause pain and injury. While there is a strong suspicion of a connection between movement disorders and EDS, there are no published studies that confirm this link. There is currently no established treatment for movement disorders in EDS patients.

Physiotherapy and cognitive behavioural therapy

While there is no cure for Ehlers-Danlos syndrome (EDS), there are a variety of treatment options available, including physiotherapy and cognitive behavioural therapy.

Physiotherapy

Physiotherapy is a common treatment for EDS patients, with two-thirds of patients reporting benefits from it in one study. Physical therapists can help in many ways, depending on the type of pain and other symptoms the patient is experiencing. They can prescribe exercises to reduce pain associated with joint instability, muscle spasms, strains, and sprains. They can also educate patients on how to improve their posture and perform daily tasks in less painful ways. In addition, they can apply gentle manual therapy to reduce pain and help with joint instability and provide tips for managing joint instability at home. It is important to work with a physical therapist to determine the best exercises for the patient, as exercises should be adapted based on each person's abilities and limitations. Exercises that focus on movement control and strengthening the stabilizing muscles are generally suitable for people with EDS. It is recommended to start with a low number of repetitions, low weight, and a short time exercising, gradually increasing these over time. People with unstable joints should avoid high-impact activities such as running and jumping, as well as contact sports and sports that focus on flexibility.

Cognitive Behavioural Therapy

Cognitive behavioural therapy (CBT) is a type of psychological intervention that can be used to enhance coping strategies for pain and address stress or low mood. CBT can be combined with physiotherapy and group therapy, followed by individual home exercises and weekly guidance by a physiotherapist, to improve muscle strength and endurance, reduce the fear of movement, and increase participation in daily life.

Musculoskeletal pain, fatigue, and headache

The Ehlers-Danlos syndromes (EDS) are a group of heritable connective tissue disorders characterized by joint hypermobility, stretchy skin, and being easily damaged. EDS patients commonly suffer from various types of headaches, including migraines, muscle tension headaches, and headaches caused by high blood pressure. Migraines are the most common form of headache in EDS patients, with up to three-quarters of patients with symptomatic joint hypermobility reporting migraines. These migraines have been linked to cervical spine and neck instability, with patients experiencing constant neck pain and headaches when moving their heads.

Musculoskeletal pain is also a common symptom of EDS, with patients experiencing muscle pain, nighttime muscle cramps, and muscle weakness. This muscle weakness may be due to avoiding exercise because of overly mobile joints. Treatment for musculoskeletal pain in EDS patients includes physiotherapy and cognitive-behavioral therapy, which have been shown to improve muscle strength and endurance.

Fatigue is another symptom associated with EDS. However, there is limited research specifically linking EDS to fatigue. Nonetheless, EDS patients may experience fatigue due to the cumulative effects of other symptoms, such as pain, insomnia, and other comorbid conditions.

In addition to the above, Idiopathic Intracranial Hypertension (IIH) has been suggested as a possible cause of headaches in EDS patients. IIH involves increased fluid pressure under the skull, resulting in symptoms such as headaches, visual disturbances, light sensitivity, tinnitus, nausea, and vomiting. While there is no direct evidence linking EDS to IIH, the high female-to-male ratio in IIH corresponds to the higher prevalence of EDS in females.

Muscle weakness and contractures

Muscle contractures are characterised by muscle tissue that is stiffer than normal and difficult to stretch. This condition arises from the permanent shortening of muscle fibres and changes in normal muscle structure. Specifically, the fundamental units of muscles, called sarcomeres, overly lengthen when muscle fibres tighten, preventing the muscle from contracting normally. This results in muscle weakness and restricted movement.

The extracellular matrix, a mesh-like web composed of collagen and other proteins that facilitate muscle contraction, experiences an increase in collagen levels during muscle contractures. This excess collagen causes a stiffening of fibres, further impeding movement. Additionally, muscle contractures can arise from a decrease in satellite cells, specialised stem cells that are crucial for muscle regeneration and repair.

Contractures can develop from upper motor neuron lesions that obstruct signals between the brain, spinal cord, and motor neurons responsible for muscle contraction. This disruption leads to muscle stiffness and weakness due to inadequate stimulation. Cerebral palsy, a disorder affecting mobility and caused by upper motor neuron lesions, often results in contractures in the hips, knees, and ankles due to insufficient stimulation of leg muscles.

Muscular dystrophy, a group of inherited neuromuscular disorders, is also characterised by muscle weakness and wasting. The lack of nerve supply to the muscles causes them to become stiff and tight, hindering the range of motion required for joint movement and muscle activation. Muscular dystrophy patients exhibit decreased levels of satellite cells, which repair muscles and help prevent muscle contractures.

Connective tissue disorders

Connective tissues are like a "cellular glue" that holds the structures of the body together. They are made up of two types of proteins: collagen and elastin. Collagen is found in tendons, ligaments, skin, cartilage, bone, and blood vessels, while elastin is found in ligaments and skin. When these connective tissues become inflamed, it can damage the proteins and surrounding areas of the body, resulting in a connective tissue disorder. There are over 200 types of connective tissue disorders, including genetic disorders such as Ehlers-Danlos Syndrome (EDS), Marfan syndrome, and osteogenesis imperfecta, as well as autoimmune disorders like lupus and scleroderma.

Ehlers-Danlos Syndrome is a group of heritable connective tissue disorders characterized by joint hypermobility and related complications, abnormal skin texture and repair, and vascular and internal organ fragility. There are six major forms of EDS: classic, hypermobility, vascular, kyphoscoliotic, arthrochalasis, and dermatosparaxis types. People with EDS may experience neurological manifestations such as musculoskeletal pain, fatigue, headaches, muscle weakness, and paresthesias. Movement disorders, such as uncontrolled muscle contractions, tremors, and twitches, have also been reported in EDS patients. While there is no established treatment for these movement disorders in EDS patients, pain medication and physiotherapy are commonly used to manage symptoms.

The diagnosis of connective tissue disorders typically begins with a physician taking a medical history and performing a neurological examination. Due to the similarity of symptoms with other conditions, diagnostic tests are crucial for ruling out other causes and confirming a diagnosis. These tests may include MRI scans of the brain and spinal cord, lumbar punctures, chest x-rays, electromyograms, and nerve or muscle biopsies.

Treatment options for connective tissue disorders vary depending on the specific disorder and can include physical therapy, occupational therapy, and medications such as corticosteroids to reduce inflammation. In some cases, surgery may be required to address specific complications arising from the disorder.

In summary, connective tissue disorders, including Ehlers-Danlos Syndrome, involve inflammation and damage to connective tissues, resulting in a range of symptoms and complications. Diagnosis and treatment vary depending on the specific disorder, and ongoing research aims to improve understanding and management of these conditions.

Frequently asked questions

Ehlers-Danlos syndrome (EDS) is a group of heritable connective tissue disorders featuring joint hypermobility and related complications, dermal dysplasia with abnormal skin texture and repair, and a variable range of hollow organ and vascular dysfunctions.

The symptoms of EDS vary depending on the type, but they can include muscle spasms, muscle pain, fatigue, headaches, muscle weakness, seizures, and joint dislocation.

Yes, EDS can cause muscle spasms and spasticity. This is due to a lack of balance in muscle tone around the joints, which can result in increased risk of subluxation or injury.
