Adhesive capsulitis
Also known as: adhesive capsulitis, frozen shoulder, primary frozen shoulder, idiopathic frozen shoulder, secondary frozen shoulder, glenohumeral capsular contracture
Adhesive capsulitis, commonly called frozen shoulder, is a painful condition characterised by progressive restriction of both active and passive glenohumeral movement. External rotation is usually particularly restricted. The condition involves inflammation, fibrosis, thickening and contraction of the shoulder-joint capsule. It may occur without a clear precipitating event or develop after injury, surgery, stroke, prolonged immobilisation or another shoulder disorder. It is more common in people with diabetes and is also associated with thyroid disease. The clinical course is often described as painful freezing, stiff frozen and recovery or thawing phases, although individual presentations vary. Symptoms can persist for many months and sometimes several years. Biomedical management may include education, activity modification, analgesia, physiotherapy-guided mobility exercises, intra-articular corticosteroid injection, hydrodilatation and, in persistent severe cases, manipulation under anaesthesia or arthroscopic capsular release. TCM differentiation commonly includes Qi stagnation and Blood stasis obstructing the shoulder, Cold-Damp Bi syndrome, Phlegm-Damp obstruction, Qi and Blood deficiency failing to nourish the sinews, or Liver and Kidney deficiency. Acupuncture may be considered as adjunctive pain and rehabilitation support but must not replace diagnostic assessment, rehabilitation, diabetes management, injection therapy or surgical referral when required.

Lifestyle & Diet
- •Maintain gentle shoulder movement within tolerable limits rather than completely immobilising the arm.
- •Follow an individualised physiotherapy or rehabilitation program.
- •Exercises should generally emphasise gradual range-of-motion restoration and later strengthening rather than forceful stretching through severe pain.
- •A temporary mild increase in discomfort may occur with rehabilitation, but severe or prolonged flare-ups indicate that intensity should be reviewed.
- •Use prescribed or pharmacist-recommended analgesia according to directions.
- •Non-steroidal anti-inflammatory medicines may be unsuitable with peptic ulcer disease, kidney disease, anticoagulant therapy, cardiovascular risk, aspirin-sensitive asthma or pregnancy.
- •Discuss intra-articular corticosteroid injection with the treating clinician when pain substantially limits movement or sleep.
- •People with diabetes should be aware that corticosteroid injections may temporarily increase blood glucose and may require monitoring according to their diabetes plan.
- •Hydrodilatation may be considered in selected patients following specialist assessment.
- •Surgery is not usually first-line but may be considered when severe restriction persists despite appropriate conservative treatment.
- •Support the affected arm with pillows when sleeping if this reduces pain.
- •Avoid repeatedly sleeping directly on the painful shoulder.
- •Use heat or cold according to comfort, protecting the skin from burns or cold injury.
- •Avoid carrying heavy loads or sudden overhead lifting during a painful flare.
- •Continue using the hand, wrist and elbow to reduce unnecessary upper-limb deconditioning.
- •Optimise diabetes and thyroid management with the treating clinician.
- •Seek review when symptoms are worsening, the diagnosis is uncertain or meaningful improvement is not occurring.
- •Recovery can be gradual and may take months or years; this does not remove the need to reassess an atypical or deteriorating presentation.
Cautions & Contraindications
- •Do not treat suspected fracture, dislocation, septic arthritis, acute coronary syndrome, pulmonary embolism or progressive neurological impairment with acupuncture or herbs alone.[,]
- •Do not perform forceful shoulder manipulation without appropriate training, diagnosis, consent and consideration of fracture and soft-tissue injury risk.[,]
- •Do not promise rapid restoration of full range of motion.[,]
- •Do not claim acupuncture or Chinese herbal medicine dissolves capsular fibrosis or cures every case of frozen shoulder.[]
- •Do not advise complete prolonged immobilisation unless specifically required by a medical or surgical condition.[,]
- •Do not encourage aggressive stretching through severe pain.[,]
- •Avoid deep unsafe needling near the lung apex, thoracic cage, axillary vessels or major nerves.[,]
- •Do not needle through recent injection sites, surgical wounds, cellulitis or damaged skin.[]
- •Avoid intense cupping, gua sha or bleeding techniques in patients using anticoagulants or with bleeding disorders.[]
- •Do not apply strong heat or moxibustion where sensation is reduced, circulation is impaired or acute inflammation is present.[]
- •Do not advise discontinuing prescribed analgesia, diabetes medication, thyroid medication or rehabilitation without consultation with the relevant clinician.[,]
- •Do not interpret worsening night pain, weight loss, fever or neurological loss as a normal healing response.[]
- •Bàn Xià must be correctly processed; raw Bàn Xià is toxic.[]
- •Blood-moving herbs including Dāng Guī, Chuān Xiōng, Táo Rén, Hóng Huā, Niú Xī and Jiāng Huáng require pregnancy, bleeding and anticoagulant review.[]
- •Gān Cǎo may affect blood pressure, potassium and medicine metabolism when concentrated or used for prolonged periods.[]
- •Avoid contaminated, adulterated, prohibited or incorrectly identified herbs.[]
- •Screen all herbal prescriptions for pregnancy, breastfeeding, liver or kidney disease, allergies and medicine interactions.[]
- •Do not use symptom improvement as evidence that shoulder structure, blood glucose or neurological function is normal.[,,]
When to reassess or seek care again
- •Immediately: reassess any suspected fracture, dislocation, septic arthritis, vascular compromise, progressive neurological loss or cardiopulmonary emergency — these override adjunctive TCM care.[,]
- •Within 2–4 weeks of starting adjunctive acupuncture: review pain, night symptoms, sleep, functional range of motion and adherence to rehabilitation.[,,]
- •At 6–12 weeks: reassess with the treating clinician if pain and passive external rotation have not meaningfully improved — corticosteroid injection or hydrodilatation may be indicated.[,,]
- •At 3–6 months: if severe restriction and disability persist despite conservative and injection therapy, refer for orthopaedic review regarding manipulation under anaesthesia or arthroscopic capsular release.[,,,]
- •Review the TCM pattern every 3–4 sessions; painful-freezing, frozen and thawing phases commonly shift emphasis between Blood-stasis, Cold-Damp, Phlegm-Damp and deficiency patterns.
- •New shoulder trauma, fall or lifting injury on the affected side.[,]
- •Shoulder or upper-limb surgery, immobilisation or prolonged sling use.[,,]
- •Contralateral frozen shoulder — the opposite shoulder can be affected within a few years.[,,]
- •Poorly controlled diabetes or newly diagnosed thyroid dysfunction.[,]
- •Post-stroke shoulder, hemiplegia, spasticity or coexisting complex regional pain syndrome.[]
- •Overly aggressive stretching, forced end-range mobilisation or return to heavy overhead work before capsular tolerance has recovered.[,]
Recovery is typically slow and non-linear. Sudden severe worsening, new neurological symptoms, systemic illness or trauma always require biomedical reassessment rather than intensified TCM treatment.
Frequently Asked Questions
What is adhesive capsulitis?+
Adhesive capsulitis, or frozen shoulder, is a condition causing progressive shoulder pain and restriction of both active and passive glenohumeral movement [3].
What movement is commonly most restricted?+
External rotation is commonly particularly restricted, although abduction, flexion and internal rotation may also be substantially reduced [3].
How long can frozen shoulder last?+
Symptoms commonly persist for many months and may take up to several years to resolve. The duration and degree of recovery vary between individuals [3].
Who is at greater risk?+
Risk is increased in people with diabetes and thyroid disease and after shoulder injury, surgery, stroke or prolonged immobilisation [3].
What are the main biomedical treatments?+
Management may include education, analgesia, physiotherapy-guided exercise, corticosteroid injection, hydrodilatation and, for persistent severe cases, manipulation under anaesthesia or arthroscopic capsular release [3].
What are common TCM patterns?+
Common patterns include Qi stagnation and Blood stasis, Cold-Damp Bi syndrome, Phlegm-Damp obstruction, Qi-Blood deficiency and Liver-Kidney deficiency [5].
Which acupuncture points may be considered?+
Pattern-dependent points may include LI15, SJ14, SI9, SI10, LI14, GB21, LI4, ST38, GB34 and distal constitutional points [5].
Can acupuncture cure frozen shoulder?+
Acupuncture may be considered as adjunctive pain and rehabilitation support, but evidence is insufficient to claim it reliably cures capsular fibrosis or replaces rehabilitation and medical care [5].
Should the shoulder be stretched forcefully?+
No. Aggressive stretching through severe pain can cause major flare-ups. Mobility work should be graded according to the condition's irritability and professional rehabilitation advice [3].
When is shoulder pain an emergency?+
Emergency assessment is needed when shoulder pain accompanies chest symptoms, breathlessness, collapse, major trauma, deformity, vascular changes, fever, severe swelling or progressive neurological loss [3].
