There are over 80 types of autoimmune diseases, and they occur when the body's immune system attacks healthy cells. While the causes of muscle shaking or tremors are often associated with Parkinson's Disease, there are other autoimmune diseases that can cause muscle shaking. Rheumatoid arthritis, for example, is an inflammatory autoimmune disease that can cause inflammation in the joints and tissues of the hands and fingers, leading to muscle weakness and nerve conditions like peripheral neuropathy and carpal tunnel syndrome, resulting in shaky hands. Sleep disturbances, such as RBD, excessive daytime sleep, and narcolepsy, are also common in autoimmune neurologic diseases, indicating that muscle shaking at night could be a symptom of an underlying autoimmune disorder.

What You'll Learn
Rheumatoid arthritis (RA)
While RA does not directly cause hand tremors, it is a common symptom experienced by people living with the disease. The inflammation caused by RA can lead to muscle weakness and nerve conditions, which may result in shaking. In addition to peripheral neuropathy and carpal tunnel syndrome, other potential causes of shaky hands include essential tremors and Parkinson's disease. The shaking caused by RA can interfere with daily activities such as writing, eating, and performing detailed tasks.
There are several strategies to manage muscle spasms and shaky hands caused by RA. Medications, hand exercises, and lifestyle modifications can help manage symptoms. Hand exercises can help stretch the hands, improve control over movements, and strengthen the muscles that move the fingers. Physical therapy can be beneficial to learn these exercises from a trained professional. Certain exercises may help reduce shaking by improving muscle strength and control. Additionally, disease-modifying antirheumatic drugs (DMARDs) are used to treat RA, but it is important to be aware of potential side effects that may lead to muscle twitching. For example, Methotrexate, a commonly used DMARD, may rarely lead to liver damage, which can disrupt electrolyte balances. If new or worsening symptoms occur after starting medication, it is crucial to consult a doctor to determine if medication adjustments are necessary.
RA can cause unstable joints in the hands, along with a creaking sound during movement, swelling, inflammation, and an inability to bend or straighten the fingers. It can also lead to rheumatoid vasculitis, which affects blood vessels and can cause numbness, tingling, burning, or pain in the hands or feet due to nerve damage. If hands or feet become so numb that they drop or go limp, it is important to seek immediate medical attention.

Neuropathy
To manage nighttime nerve pain associated with neuropathy, Dr. Farhad suggests several strategies. Maintaining a warm bedroom environment is important because cold temperatures can worsen neuropathy pain. Creating a relaxing nighttime routine, such as stopping screen usage an hour or two before bed, can also help. For those with painful feet, wearing soft or diabetic socks can provide comfort. Additionally, timing pain medication appropriately can be beneficial; a partial or lower dose may be sufficient during the day, but taking a dose of pain medication in the evening before bed can help manage nighttime pain. Over-the-counter topical pain relievers, such as capsaicin or lidocaine, can also be applied to the skin to alleviate pain.

Carpal tunnel syndrome
The treatment for carpal tunnel syndrome typically begins with non-surgical, conservative approaches. These include modifying daily routines, supporting and strengthening the wrist, and taking medication. Wearing a splint, especially at night, can help hold the wrist in a neutral position to relieve pressure on the median nerve. Physical therapy can strengthen the muscles around the wrist and improve flexibility. Occupational therapy can suggest posture and working environment changes to perform everyday tasks more safely and comfortably. Over-the-counter medications, such as NSAIDs or acetaminophen, can help reduce inflammation and relieve pain. If conservative treatments are ineffective, carpal tunnel surgery may be considered.
It is important to consult a healthcare provider to confirm a diagnosis of carpal tunnel syndrome and explore suitable treatment options. They can recommend specific exercises, lifestyle modifications, or medications to manage the condition effectively.

Parkinson's disease
The frequency of a PD tremor is about 3-6 Hz, meaning the affected body part moves back and forth about 3-6 times a second, although this can vary, with younger patients tending to have faster tremors. PD tremors are almost universally asymmetric, meaning they are different on each side of the body. Fatigue, stress, and intense emotions can temporarily worsen tremors.
In addition to tremors, PD can cause a range of motor and non-motor symptoms. Motor symptoms refer to any symptom that makes it harder to move or control movements, such as stiff muscles, problems with balance or coordination, and unusually slow movements (bradykinesia). Non-motor symptoms may impact mood, the sense of smell, or vision, among other things.
Sleep problems are also common in people with PD, with up to 2 in 3 patients experiencing trouble sleeping. These sleep issues can manifest as insomnia, fragmented sleep, excessive daytime sleepiness, and very vivid dreams, which may cause hallucinations or confusion upon waking. Sleep apnea and restless leg syndrome are also common in the later stages of PD. These sleep disturbances may be linked to chemical changes in the brain that disrupt sleep-wake cycles and medication side effects.

Sleep disturbances
Sleep myoclonus is not a disease but a symptom of several different conditions. It typically occurs during the early stages of sleep, especially when a person is transitioning from wakefulness to sleep. The movements associated with sleep myoclonus include hiccups, starts, and jerks, which can affect a single muscle or multiple muscle groups. While sleep myoclonus is generally harmless, it can interfere with sleep quality and cause difficulty falling asleep.
One specific type of sleep myoclonus is the hypnic jerk, also known as a sleep start or night start. A hypnic jerk is a sudden, involuntary muscle twitch that often feels like a jolt or a falling sensation. It usually affects one side of the body and may be accompanied by a brief dream or a startled feeling. Hypnic jerks are common and generally harmless, but they can be more frequent during times of stress, fatigue, or excessive caffeine consumption.
Another type of sleep myoclonus is restless leg syndrome (RLS), which causes uncomfortable sensations in the legs, such as tingling, crawling, or itching. RLS leads to an irresistible urge to move the legs, especially at night, and can interfere with falling asleep. RLS is believed to be a neurological condition, but its exact cause is unknown. It is often associated with other sleep disorders and can occur alongside sleep myoclonus.
In some cases, sleep myoclonus may be a symptom of an underlying neurological or autoimmune disease. For example, myoclonus has been linked to multiple sclerosis, Parkinson's disease, dementia with Lewy bodies, Alzheimer's disease, celiac disease, epilepsy, and autoimmune encephalitis. Dystonia, a movement disorder characterised by repetitive and sustained muscle contractions, can also be associated with autoimmune syndromes such as chronic inflammatory demyelinating polyneuropathy (CIDP).
If you are experiencing sleep disturbances or involuntary muscle twitches at night, it is important to consult a healthcare professional to determine the underlying cause and explore appropriate treatment options.
