Frozen Shoulder: How Long Does Recovery Take, and How Can Physiotherapy Help?

What Is Frozen Shoulder?

Frozen shoulder (adhesive capsulitis) is a condition in which the capsule surrounding the shoulder joint becomes inflamed, thickened and tightened, dramatically restricting movement and causing significant pain. It affects around 2–5% of the general population, most commonly between the ages of 40 and 60, and is more prevalent in women and in people with diabetes (Li, et al., 2025).

The Three Stages of Frozen Shoulder

Frozen shoulder typically progresses through three overlapping stages, freezing, frozen and thawing, though the exact timing and pattern varies considerably from person to person (Li, et al., 2025).

Stage 1: Freezing (2–9 months)

Gradually increasing shoulder pain, often worse at night. Movement begins to restrict. This is often the most painful stage.

Stage 2: Frozen (4–12 months)

Pain may begin to settle but stiffness is at its maximum. Daily activities such as reaching, dressing and driving become very difficult.

Stage 3: Thawing (5–24 months)

Movement gradually returns and pain reduces. Full or near-full recovery is achieved in most cases, but this can take months to years without treatment.

How Physiotherapy Accelerates Recovery

Physiotherapy at each stage focuses on managing pain, protecting movement and rebuilding function, rather than promising to fast-track the underlying healing process. Left untreated, frozen shoulder can last 1–3 years (Li, et al., 2025).

It's worth being honest about the evidence here: a Cochrane review of manual therapy and exercise for frozen shoulder found the data did not show physiotherapy outperforming corticosteroid injection in the short term, and much of the evidence for specific physiotherapy techniques remains low quality (Page, et al., PMC10882424, 2014). What physiotherapy reliably offers is structured pain management, guidance on safe movement at each stage, and support to avoid the secondary stiffness and deconditioning that can come from avoiding the arm altogether, which most patients find meaningfully improves quality of life even where it does not necessarily shorten the overall natural history:

• Freezing stage: Pain management techniques, gentle movement to slow further restriction, and education to reduce anxiety about the condition.
• Frozen stage: Progressive stretching and joint mobilisation to prevent further tightening and begin restoring range of motion.
• Thawing stage: More aggressive range-of-motion work, strengthening and functional rehabilitation to restore full shoulder use.

What Can I Do at Home?

A few simple, consistent habits between physiotherapy sessions can help manage symptoms and protect movement:

• Apply heat before exercise (15 minutes) and ice after (10–15 minutes)
• Perform gentle pendulum exercises, let the arm hang freely and make small circles
• Avoid sudden overhead movements that cause sharp pain
• Continue using the arm within a pain-tolerable range, immobility worsens stiffness

Will I Need Surgery?

Most people do not need surgery for frozen shoulder. With appropriate management, including physiotherapy, around 80% of patients regain near-normal or normal shoulder function over time (Li, et al., 2025). Surgical intervention (manipulation under anaesthetic or arthroscopic capsular release) is considered only for cases that fail to respond to extended conservative management.
