Frozen Shoulder (Adhesive Capsulitis) Guide and Our Biomechanical Approach

The locking feeling you experience when moving your shoulder and the severe pain that wakes you up from sleep at night may not just be a simple muscle stiffness, but a biomechanical problem of your shoulder joint capsule. This condition, which lasts for a long time and severely restricts activities of daily living (ADL), is called Frozen Shoulder (Adhesive Capsulitis) in literature. In this article, we will examine the role of physical therapy and the rehabilitation process in frozen shoulder cases diagnosed by a specialist doctor, based on current scientific sources.

What Do You Experience Biomechanically and Neurophysiologically?

According to Kinetic Chain Principles, the shoulder joint is the most mobile joint of our body, but the one that needs stability the most. In the clinical picture of frozen shoulder, the following anatomical and mechanical changes are observed:

1. Capsular Contraction (Fibrosis): Frozen shoulder is the thickening and contraction (fibrosis) of the joint capsule that surrounds the shoulder joint like an envelope. This contraction reduces the joint space, leading to friction between the two bones and physically locking the movement.
2. Kinetic Chain Compensation: When the shoulder joint is locked, the brain involuntarily starts to use the muscles around the neck and shoulder blade (scapula) in order to lift the arm. This compensation mechanism paving the way for neck hernia-like complaints and serious posture asymmetries over time.

Secondary Symptoms Alarm: What are the Symptoms?

In cases of frozen shoulder, the following symptoms are frequently experienced due to the compensatory responses given by the body, not only in the shoulder:

• Aches that wake you up from sleep when lying on the side of the problematic shoulder at night.
• Severe limitation in basic movements such as combing hair, reaching behind (bra strap fastening movement), or reaching for a high shelf.
• Secondary muscle spasms starting from the shoulder and spreading to the neck, shoulder blade, and arm.

Who is Threatened by Risk Factors?

According to international guidelines, some systemic and physical risk factors that can trigger the development of frozen shoulder are:

• Diabetes: The risk of developing frozen shoulder in diabetes patients is significantly higher compared to the normal population.
• Thyroid Diseases: Thyroid dysfunctions can affect connective tissue quality.
• Trauma and Immobility: Keeping the arm in a sling (immobility) for a long time due to a shoulder fracture, shoulder surgery, or another ailment can cause the capsule to harden.

Physical Therapy and Rehabilitation Process (Implementation Steps)

In the rehabilitation process planned after the diagnosis of your specialist doctor, internationally accepted manual mobilization concepts such as Maitland and Mulligan are applied. The purpose of this process is not to force the joint, but to manage the brain's perception of pain and stretch the tissue gradually.

What is Dynamically Targeted in the Session?

1. Joint Mobilizations: In the painful and acute (freezing) phase, the physiotherapist helps manage sensitivity around the tissue with soft and rhythmic sliding techniques. When the shoulder passes to the "thawing" phase, the contracted capsule tissue is stretched in a controlled manner with more specific mobilizations.
2. Kinetic Chain Corrections: In the Mulligan (MWM) concept, minor biomechanical alignment errors in the joint are corrected with manual support. Exercises performed with this instant support help gain range of motion (ROM) more comfortably.
3. Myofascial Release: Since the locked shoulder puts excessive load on the neck and back muscles, "trigger points" are formed in these areas. It is aimed to reduce referred pain by supporting circulation in these areas with manual pressure (Ischemic Compression) techniques.

Implementation Phases: How Does the Process Work?

Frozen shoulder rehabilitation is shaped according to the phase of the discomfort and is a process that requires patience:

• Phase 1 (Acute/Freezing): The main focus is to improve night sleep quality and support pain control. Simple pendulum (Codman) exercises start with doctor and physiotherapist approval.
• Phase 2 (Mobility/Frozen Phase): This is the phase in which the range of motion (ROM) is gradually and safely increased with manual applications.
• Phase 3 (Stabilization and Thawing): It is aimed to protect the newly gained angles by strengthening them with clinical exercises and Clinical Reformer Pilates.

"Dangerous Mistakes" Not to Do!

• Excessive Forcing (Breaking Yourself): Having someone pull the arm suddenly or harshly so that the shoulder opens can cause capsule tears and serious tissue damage.
• Keeping the Arm Completely in a Sling (Immobility): Unless recommended by the doctor, leaving the arm completely immobile accelerates the freezing of the capsule.
• Unconscious and Hard Massage: Trying to solve a deep capsular problem in the joint by simply crushing the superficial muscles can increase tissue sensitivity.
