Physical Therapy for Frozen Shoulder: Stages, Causes, and Treatment
Physical therapy for frozen shoulder is one of the most effective ways to ease the pain and restore the normal range of motion of the shoulder. Frozen shoulder, also called adhesive capsulitis, happens when the capsule surrounding the shoulder joint thickens and tightens, leaving the shoulder painful and progressively stiff over a period of months before it slowly recovers. It moves through predictable stages, and the treatment that helps depends on which stage you are in. This guide explains the stages, the causes, and how physical therapy for frozen shoulder restores your motion.
What frozen shoulder actually is
The shoulder joint is surrounded by a capsule of connective tissue. In frozen shoulder, that capsule becomes inflamed, thickens, and tightens. As it tightens, the shoulder loses range of motion in a specific pattern, and everyday movements like reaching behind your back or overhead become difficult.
When I evaluate a shoulder, what points to a frozen shoulder rather than another pathology is a specific pattern of lost motion called a capsular pattern. With a frozen shoulder, the movements that get restricted in order are rotating your arm outward to the side (external rotation), then raising it out to the side (abduction), followed by the arm behind your back (internal rotation). And unlike most shoulder issues, that stiffness is present during both active and passive movement, which is the telltale sign that the joint capsule itself has tightened down.
The good news is that physical therapy is the main treatment for frozen shoulder, and we walk through exactly how it works below.
The three stages of frozen shoulder
- Freezing stage: Pain increases and the shoulder gradually stiffens. This stage can last a few months and is often the most painful.
- Frozen stage: The pain may ease somewhat, but stiffness is at its worst. Motion is significantly limited. This stage can last several months.
- Thawing stage: Motion slowly returns over months as the capsule loosens.
Knowing your stage matters because aggressive stretching in the painful freezing stage can make things worse, while the frozen and thawing stages respond well to more assertive mobility work.
What causes frozen shoulder
Frozen shoulder can be idiopathic, meaning it can appear without a known cause. With that being said, the risk is higher after a period of shoulder immobilization, such as after an injury or surgery, and in people with diabetes and certain thyroid conditions. It is also more common in the 40 to 60 age range and more common in women.
How physical therapy helps a frozen shoulder
Physical therapy is one of the main treatments for frozen shoulder. The approach is matched to your stage: pain reduction and gentle motion early, then progressively restoring range of motion and strength as the shoulder allows. Hands-on manual therapy helps restore joint mobility, and a targeted home program keeps the motion you gain. At Reclaim Physical Therapy, the whole plan is built around the stage you are actually in, not a generic protocol. The goal is to move through the stages faster and end up with a shoulder that moves normally. In my practice, I have noticed that a combination of gentle activation exercises, joint mobilization, and stretching has been most effective in the treatment of frozen shoulder.
Treatment for frozen shoulder
Joint mobilization for frozen shoulder
Joint mobilization is a hands-on technique where gentle pressure and graded movements are applied to the shoulder joint to restore the gliding motion the tightened capsule has taken away. For frozen shoulder, it is one of the most effective ways to gradually win back range of motion, especially in the frozen and thawing stages, without the aggressive stretching that only flares the joint up in the early phase.
Dry needling for frozen shoulder
The muscles around a frozen shoulder often develop trigger points as they guard against pain, and those knots limit motion even further. Dry needling releases them, and a growing body of research supports it as a helpful addition to care. Published case reports have shown meaningful improvements in pain-free range of motion and function when dry needling is added to standard treatment for frozen shoulder. It works best as one piece of a full plan alongside manual therapy and exercise, not on its own.
What not to do with a frozen shoulder
Do not force painful, aggressive stretching during the early, painful stage. That tends to flare the shoulder and set you back. And do not simply rest and wait it out, because prolonged immobility can worsen stiffness. The right answer is stage-appropriate movement guided by a physical therapist who can properly assess and plan the appropriate treatment.
How we treat frozen shoulder at Reclaim
At Reclaim Physical Therapy, we identify your stage, use hands-on manual therapy to restore joint motion, along with adjunct tools such as dry needling with electrical stim, and IASTM such as cupping and scraping, along with building a home program that fits. Because we are a concierge, in-home practice serving Weston and the surrounding area, we bring the full session to you, which makes a consistent, hands-on program much easier to stick with over the months a frozen shoulder takes to resolve.

Frequently asked questions
Can physical therapy fix frozen shoulder?
Physical therapy is a primary treatment. Stage-matched hands-on work and exercise restore motion and can shorten the course.
Who gets frozen shoulder?
It is more common between ages 40 and 60, in women, after shoulder immobilization, and in people with diabetes or thyroid conditions.
How long does frozen shoulder last?
It moves through stages and can take a year or more to fully resolve, though the right treatment can speed recovery and improve the outcome.
What are the stages of frozen shoulder?
Freezing (increasing pain and stiffness), frozen (worst stiffness), and thawing (motion slowly returns).
What makes frozen shoulder worse?
Aggressive stretching during the painful early stage, and long periods of not moving the shoulder at all.
