Inclusion Body Myositis (IBM)

What is Inclusion Body Myositis?

Inclusion body myositis (IBM) is the most common type of autoimmune muscle disease in people older than 50.^[1] It causes slowly progressive weakness and wasting, with a typical pattern of weaker thigh (quadriceps) and finger-flexor muscles.^{[1, 2]} IBM needs diagnosis and long-term care from a neuromuscular or rheumatology specialist.

For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care.

Common symptoms

IBM usually starts slowly, after age 45, and the weakness is often uneven between the two sides at first.^[1] Typical features include:

• Weak thigh muscles, causing trouble standing from a chair, climbing stairs or walking, and falls
• Weak finger flexors, making gripping, buttoning and other fine tasks harder
• Swallowing difficulty (dysphagia), which affects many people and adds to illness and risk^[3]
• Fatigue with activity

Causes and risk factors

The cause is not fully known. IBM has features of both a T-cell-driven autoimmune process, in which immune cells invade muscle fibers, and abnormal protein build-up inside muscle cells.^[2] Age over 45 or 50 is the main known risk factor.^{[1, 4]}

How it is diagnosed and treated conventionally

Diagnosis combines the pattern of weakness, a blood test for muscle enzymes (creatine kinase, which is usually only mildly raised) and muscle biopsy findings. Published criteria are very specific but not very sensitive.^[1]

No drug has been shown to slow IBM. A 2025 systematic review of 14 randomized trials of immune-suppressing and other drugs, including methotrexate and intravenous immunoglobulin, found no effect on progression in most outcomes.^[5] Exercise remains the main treatment available.^[3] Supervised exercise has been reported as safe in myositis, and blood-flow-restricted resistance training helped preserve thigh strength in IBM in one study.^[6]

Why Inclusion Body Myositis calls for a whole-person approach

IBM affects mobility, independence, eating, mood and sleep, and its drug treatments are limited. The medical team therefore relies heavily on rehabilitation, swallowing care, fall prevention and assistive devices.^[3]

Supportive care aims at the symptoms that come with living with the disease, and it cannot change its course.

Muscle use and exercise

Exercise is the only widely used therapy for IBM, and the benefit depends on supervision. It is advised to start at low intensity with a physical therapist and progress gradually.^[6] Anything we do should fit that plan.

Swallowing and nutrition

Dysphagia is one of the most serious complications because of its effect on illness and mortality in IBM.^[3] Swallowing changes should be reported to your specialist rather than managed with herbs or supplements alone.

Pain, stress and sleep

Aching muscles, joint strain from altered movement, worry about progression and poor sleep are common in chronic illness. The studies below are not in people with IBM, so their results may not apply directly.

Balance and falls

Yoga has been proposed as a complementary approach in myositis and other muscle disorders. A review found that evidence in inflammatory myositis is in its infancy, although results in other disorders suggested better strength, balance and fewer falls in older adults.^[7]

Acupuncture as supportive care in Inclusion Body Myositis

What the research shows

There are no clinical trials of acupuncture for inclusion body myositis. We found none in PubMed, and nothing suggests that acupuncture can improve muscle strength, slow progression or change the biology of the disease.

Evidence from other conditions is limited to symptom relief. An individual patient data meta-analysis of 39 trials with 20,827 patients found acupuncture eased chronic musculoskeletal, osteoarthritis, headache and shoulder pain more than no acupuncture and, by a smaller margin, more than sham acupuncture.^[8] Those patients did not have IBM.

For swallowing, trials of acupuncture have been done in Parkinson's disease. A meta-analysis of 10 trials found better swallowing scores when acupuncture was added to usual care, but most trials had a high or uncertain risk of bias.^[9] This does not show that acupuncture helps IBM-related dysphagia, which has a different cause. In chronic fatigue syndrome, a review of 16 studies of mostly low quality reported lower fatigue with acupuncture but could not reach a firm conclusion, and its relevance to IBM is unknown.^[10]

How acupuncture may work

No mechanism by which acupuncture might act in IBM has been studied, so we make no claim about it. In chronic pain generally, the pooled analysis above found effects beyond those of sham acupuncture, but it does not explain how acupuncture works.^[8]

What treatment involves

Treatment uses fine, sterile, single-use needles, usually left in place for about 20 to 40 minutes, over a short course of visits followed by reassessment.

In prospective studies, about 9 in 100 patients had a minor reaction such as brief bleeding or soreness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[11] Tell the practitioner first if you take blood thinners, have a bleeding disorder, have a pacemaker (relevant to electroacupuncture) or an implanted device, or have trouble lying flat because of swallowing or breathing problems. Because weakness raises fall risk, tell the practitioner about any difficulty with positioning or getting on and off the treatment table.

Ayurvedic medicine as supportive care in Inclusion Body Myositis

The Ayurvedic view

Ayurveda has no named equivalent of IBM. Progressive muscle wasting and weakness is traditionally discussed as a Vata disorder involving depletion of the muscle tissue (mamsa dhatu). This is a traditional framework, not a medical diagnosis.

Therapies that may be used

Traditional supportive care is gentle and individualized. It may include warm, nourishing meals, regular daily routines, calm sleep habits, gentle warm-oil massage and breathing practices. Yoga is sometimes used as well, adapted to the person's strength and balance.

Panchakarma and other strong cleansing therapies are not appropriate for people with a progressive weakening illness, frailty, swallowing difficulty or acute illness.

What the research shows

There are no clinical trials of Ayurvedic treatment for inclusion body myositis. Evidence for symptoms in other groups is limited. For example, a meta-analysis of 5 trials with 400 adults found that ashwagandha extract had a small effect on sleep, but data on safety were limited.^[12] A meta-analysis of 12 trials found that ashwagandha lowered anxiety and stress scores compared with placebo, with low certainty evidence.^[13] None of these trials were in people with IBM.

Herbal medicine as supportive care in Inclusion Body Myositis

Herbs and formulas that have been studied

No herb or formula has been studied in inclusion body myositis. Herbs in supportive use are chosen for symptoms such as stress, poor sleep or muscle ache, and are prescribed individually by a qualified practitioner. Ashwagandha is the herb discussed above for stress and sleep.

What the research shows

There is no evidence that any herb treats IBM or slows its progression. The research on herbs for stress and sleep in other groups is low certainty.^{[12, 13]} Because the standard drugs for IBM have not proven effective,^[5] it is especially important not to treat a herb as a substitute for specialist care.

Safety and herb-drug interactions

Many people with IBM are older and take several medicines, and some have taken immune-suppressing drugs. Herb-drug interactions can be serious, and a literature review described them with blood thinners, antidepressants and immunosuppressants.^[14]

Ashwagandha has been linked to liver injury in case series, including prolonged cholestatic jaundice in the US and Iceland, and in one Indian series, three patients with underlying chronic liver disease developed acute-on-chronic liver failure and died.^{[15, 16]} Herbal and dietary supplements in general are a recognized cause of liver injury.^[17] Tell us about liver disease, kidney disease, pregnancy or breastfeeding and every medicine you take. About one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic, so any product should come from a tested source.^[18] Herbs that affect swallowing or are difficult to swallow in pill form should be discussed with your speech-language pathologist.

Translating traditional medicine into modern biological language

This is interpretation, not equivalence. Chinese medicine usually describes muscle weakness and wasting as deficiency of qi, spleen and kidney with poor nourishment of the muscles. Ayurveda describes depleted muscle tissue with aggravated Vata. Researchers do not have a model linking these ideas to the T-cell and protein-aggregation changes found in IBM muscle.^[2]

What the traditions share with modern care is attention to nutrition, rest, stress and gentle movement. Those are areas where a supportive practitioner may help you with symptoms while your specialists manage the disease.

How this care fits with your medical care

Supportive care follows medical care. Keep your appointments with your neurologist or rheumatologist, physical therapist, occupational therapist and speech-language pathologist. Do not stop or change prescribed treatment or therapy without your care team.

We do not diagnose or manage IBM. Please bring your diagnosis, muscle biopsy or other test results, a list of all medicines and supplements, and your therapists' guidance about exercise and swallowing.

When to seek urgent medical care

IBM can lead to serious complications that need medical attention.

• Choking, coughing or a wet voice when eating or drinking, or a sudden swallowing problem
• Fever, cough or shortness of breath, which can signal aspiration pneumonia
• Trouble breathing or breathing that seems weak
• A fall with head injury, or severe pain after a fall
• Sudden new or rapidly worsening weakness
• Yellow skin or eyes, dark urine or severe itching after starting an herbal product

If any of these occur, call 911 or go to the nearest emergency department.
