Few conditions are as frustrating — or as misunderstood — as frozen shoulder. One day you can reach for a seatbelt without thinking, and a few months later you cannot put on a coat without grimacing in pain. At Denovo Physio & Rehab in Preston, frozen shoulder is one of the most common conditions we treat, and the right combination of physiotherapy, manual therapy, electrotherapy and shockwave therapy can dramatically shorten what is otherwise a very long natural recovery.
This guide explains the three stages of frozen shoulder, why it happens, and exactly how our team in Preston combines our full treatment menu to move you through each stage faster and with less pain.
What Is a Frozen Shoulder?
Frozen shoulder — clinically known as adhesive capsulitis — is a condition where the capsule surrounding the shoulder joint becomes inflamed, thickens, and contracts. This causes progressive pain and loss of movement in all directions, particularly reaching behind the back, lifting overhead and rotating the arm outwards.
It affects around 2–5% of the general population, most commonly between the ages of 40 and 60, and is more frequent in women. People with diabetes, thyroid conditions or a recent period of shoulder immobilisation are at higher risk.
The Three Stages of Frozen Shoulder
Stage 1: Freezing (Painful Stage) — 6 weeks to 9 months
The shoulder becomes increasingly painful, particularly at night. Pain often disturbs sleep and feels worse when lying on the affected side. Range of movement begins to reduce, though many people do not yet realise their shoulder is stiffening.
Stage 2: Frozen (Stiff Stage) — 4 to 12 months
The pain starts to settle, but stiffness becomes the dominant problem. Everyday tasks — dressing, brushing hair, fastening a bra, reaching into a back pocket — become difficult. This is the stage where most patients in Preston seek physiotherapy, and where shockwave therapy can make a significant difference.
Stage 3: Thawing (Recovery Stage) — 6 months to 2 years
Movement gradually returns. With targeted physiotherapy, this stage can be significantly shortened and the final range of movement can be maximised.
Left entirely untreated, the whole cycle can take 2–4 years. With our combined manual therapy, electrotherapy, structured loading and — where appropriate — shockwave therapy, we routinely help patients in Preston recover meaningfully faster.
What Causes Frozen Shoulder?
In around 70% of cases there is no clear trigger — this is called primary frozen shoulder. Secondary frozen shoulder is associated with:
- Diabetes (5x increased risk)
- Thyroid disorders
- A period of immobilisation after fracture or surgery
- Rotator cuff injuries or calcific tendinopathy
- Cardiovascular disease and stroke recovery
How Denovo Physio Treats Frozen Shoulder in Preston
Frozen shoulder needs different treatment at different stages. Aggressive stretching in the painful stage often makes things worse. Gentle mobilisation and pain modulation in the stiff stage is exactly what is needed. Here is how we apply our full treatment menu across each stage.
Treatment in the Painful (Freezing) Stage
- Pain education and reassurance — understanding the condition reduces fear and improves outcomes
- Gentle pain-relieving manual therapy to the shoulder capsule and surrounding muscles
- Advanced Electrotherapy — TENS and Interferential Current (IFC) for deep pain modulation, ideal in this irritable stage
- Sleep positioning advice and night-time strategies
- Pendulum exercises and very gentle pain-free range of motion work
- Discussion of medical management options including referral for hydrodilatation or corticosteroid injection where appropriate
Treatment in the Stiff (Frozen) Stage
- Progressive manual mobilisation of the glenohumeral joint
- Soft tissue work on the surrounding rotator cuff, deltoid and pectoral muscles
- Structured stretching programme into external rotation, abduction and internal rotation
- Scapular control retraining using our Muscle Intelligence™ biofeedback technology
- Shockwave therapy where capsular tightness, secondary muscle trigger points or calcific deposits are limiting progress
- Strengthening of the rotator cuff and periscapular muscles in our clinical gym
Treatment in the Thawing Stage
- Functional strengthening tailored to your work, hobbies or sport
- End-range mobility work
- Return to lifting, overhead activities and sport
How Shockwave Therapy Helps Frozen Shoulder
Our Shockwave Therapy service is one of the most valuable tools we have at Denovo for frozen shoulder cases that are not progressing with hands-on physiotherapy alone. While shockwave does not directly treat the joint capsule itself, it addresses several of the secondary problems that keep frozen shoulder patients stuck — and a growing body of clinical evidence supports its use in the stiff and thawing stages.
1. Reducing Surrounding Muscle Tightness
When the shoulder capsule contracts, surrounding muscles — particularly the upper trapezius, levator scapulae, infraspinatus, teres minor and pectoralis minor — go into protective spasm. These secondary tight bands become a pain source in their own right. Radial shockwave therapy is highly effective at releasing these myofascial trigger points.
2. Treating Coexisting Calcific Tendinopathy
A significant proportion of frozen shoulder cases coexist with calcific deposits in the rotator cuff. Shockwave therapy is the gold-standard non-invasive treatment for calcific tendinopathy, and resolving these deposits dramatically improves both pain and movement.
3. Stimulating Blood Flow and Tissue Healing
Shockwave therapy increases local blood flow and triggers the body’s natural healing response in the soft tissues around the joint, breaking the cycle of stagnant tissue change.
4. Pain Reduction in Stubborn Cases
For patients who have already had hydrodilatation, corticosteroid injection or several months of physiotherapy without resolution, shockwave therapy offers a non-invasive option that frequently breaks the pain cycle and allows more productive hands-on treatment and exercise.
Typically, we deliver 3–6 weekly shockwave sessions integrated into your overall physiotherapy programme. It is never used as a stand-alone treatment — it is most effective when combined with our manual therapy, electrotherapy and progressive loading, which is exactly how we structure your sessions at Denovo.
Book Frozen Shoulder Physiotherapy in Preston
If your shoulder has been progressively painful or stiff for more than a few weeks, do not wait. Early-stage frozen shoulder responds much better than late-stage. Book an assessment at Denovo Physio & Rehab in Preston — we will tell you exactly which stage you are in, whether shockwave therapy is right for you, and what your next 6–12 weeks of recovery should look like.
