Whether you are recovering from knee surgery, rehabbing a frozen shoulder, or working with a client who just had a stroke, passive movement is one of the first tools that enters the recovery equation. It is the quiet foundation that keeps joints mobile, tissues healthy, and the body ready for the active work that comes later.

Yet despite how common passive movement is in physiotherapy clinics, personal training studios, and rehabilitation centers around the world, many people misunderstand what it actually involves, when it should be used, and how it fits into the bigger picture of recovery. Some confuse it with stretching. Others assume it is only for severely injured patients. And many fitness professionals overlook it entirely, even though it can be a powerful addition to their programming toolkit.

This guide breaks down everything you need to know about passive movement, from its clinical definition and the three main types to 10 practical exercises organized by joint, the science behind its benefits, and a clear framework for progressing from passive to active movement. Whether you are a physiotherapist, a fitness coach, or someone navigating your own recovery, this is your complete resource.

What Is Passive Movement?

Passive movement is any movement of a joint or body segment that is performed entirely by an external force, with no voluntary muscle contraction from the person being moved. That external force can come from a physiotherapist, a caregiver, a training partner, or a mechanical device like a continuous passive motion (CPM) machine.

The key distinction is that the muscles surrounding the joint remain relaxed throughout the movement. The person receiving the passive movement does not actively contract any muscle to produce or assist the motion. The therapist or device provides 100% of the force required to move the joint through its available passive range of motion.

This is different from active movement, where the individual uses their own muscular effort to move a joint, and different from active-assistive movement, where the individual initiates the motion but receives external help to complete it.

How Passive Movement Differs from Active Movement

Understanding the distinction between passive and active movement is essential because it determines which approach is appropriate at each stage of recovery. Here is the core difference:

In passive movement, the patient relaxes completely while an external force moves the joint. There is no muscle activation, no energy expenditure from the patient, and no voluntary effort involved. The goal is to maintain or restore joint mobility without placing any demand on the healing tissues.

In active movement, the patient contracts their own muscles to produce the joint motion. This requires neuromuscular control, strength, and coordination. Active movement builds on the foundation that passive movement establishes.

For a deeper comparison of when each approach is appropriate, see our guide on active vs passive range of motion.

Types of Passive Movement

Not all passive movements are the same. In clinical practice, passive movement is classified into three main types based on the amount of force applied, the speed of movement, and the method used.

Relaxed Passive Movement

Relaxed passive movement is the most common and gentle form. The therapist moves the joint slowly and smoothly through its pain-free range of motion while the patient remains completely relaxed. There is no attempt to push beyond the available range or to stretch the tissues aggressively.

When it is used: Early post-operative recovery, acute injury phases, neurological conditions where voluntary movement is absent (stroke, spinal cord injury), and situations where pain prevents active movement.

How it is performed: The therapist supports the limb above and below the joint, moves it through the full available range in a controlled manner, and returns it to the starting position. Each repetition takes 3 to 5 seconds in each direction.

Key benefits: Maintains joint mobility, prevents adhesion formation, promotes synovial fluid circulation, and provides sensory input to the nervous system.

Forced Passive Movement

Forced passive movement (also called stretching or forced manipulation) involves applying an external force at or beyond the end range of the joint's current mobility. Unlike relaxed passive movement, this technique intentionally pushes into restricted range to increase flexibility and break down adhesions or scar tissue.

When it is used: Chronic stiffness, joint contractures, adhesive capsulitis (frozen shoulder), and post-immobilization rehabilitation where significant range of motion has been lost.

How it is performed: The therapist moves the joint to its current end range, then applies a sustained or oscillatory force to push slightly beyond that range. This is done carefully, with constant communication about pain levels.

Key benefits: Increases joint range of motion, lengthens shortened soft tissues, breaks down adhesions, and restores functional mobility.

Important caution: Forced passive movement should only be performed by qualified professionals. Excessive force can damage healing tissues, cause inflammation, or worsen the condition.

Continuous Passive Motion (CPM)

Continuous passive motion uses a motorized device to move a joint through a preset range of motion at a controlled speed, continuously and without any patient effort. CPM machines are most commonly used for the knee following total knee replacement surgery, but versions exist for the shoulder, elbow, wrist, and ankle.

When it is used: Post-surgical rehabilitation (especially after total knee arthroplasty, ACL reconstruction, and rotator cuff repair), and situations where consistent, prolonged passive movement is needed.

How it works: The patient's limb is secured in the machine, which moves the joint through a programmed arc of motion. The range, speed, and duration are set by the physiotherapist and gradually increased as healing progresses. Sessions typically last 1 to 2 hours and may be repeated several times daily in the early post-operative period.

Key benefits: Reduces post-surgical swelling, promotes cartilage healing through synovial fluid circulation, prevents joint stiffness, and decreases pain in the early recovery window.

Current evidence: While CPM was widely used for decades, recent research has produced mixed results regarding its long-term superiority over standard physiotherapy alone. Many clinical guidelines now recommend CPM as one option within a broader rehabilitation program rather than a standalone treatment.

Benefits of Passive Movement

Passive movement delivers a range of physiological and functional benefits that make it an essential component of rehabilitation and recovery programs.

1. Maintains Joint Range of Motion When a joint is immobilized due to injury, surgery, or neurological damage, the surrounding soft tissues (muscles, tendons, ligaments, joint capsule) begin to shorten and stiffen within days. Passive movement counteracts this process by regularly taking the joint through its available range, preventing the formation of adhesions and contractures.

2. Promotes Synovial Fluid Circulation Synovial fluid is the lubricant that nourishes joint cartilage, reduces friction, and supports smooth joint movement. Passive movement stimulates the production and distribution of synovial fluid throughout the joint space, which is especially important during periods of immobility when the joint would otherwise become "dry" and stiff.

3. Improves Blood Flow and Reduces Swelling The rhythmic motion of passive movement acts as a gentle pump for the circulatory and lymphatic systems. This improved blood flow delivers oxygen and nutrients to healing tissues while helping to remove metabolic waste products, inflammatory markers, and excess fluid that contribute to post-surgical or post-injury swelling.

4. Provides Sensory Input to the Nervous System Even without active muscle contraction, passive movement stimulates mechanoreceptors (sensory nerve endings) in the joint capsule, ligaments, and surrounding tissues. This sensory input helps maintain the brain's awareness of joint position (proprioception) and prevents the neural pathways associated with movement from deteriorating during immobilization.

5. Reduces Pain Gentle passive movement activates the "gate control" mechanism of pain modulation. The sensory signals generated by joint movement can override or reduce pain signals traveling to the brain. This is one reason why patients often report feeling better after a passive movement session, even when the joint is still healing.

6. Prevents Muscle Atrophy (Partially) While passive movement does not produce the same muscle-building stimulus as active exercise, research suggests that it can partially slow the rate of muscle atrophy during immobilization. The mechanical loading of tissues and the neural stimulation provided by passive movement help preserve some muscle mass and tissue integrity.

7. Supports Psychological Recovery Being unable to move a body part can be psychologically challenging. Passive movement gives patients a sense of progress and participation in their recovery, even when they cannot yet move independently. This psychological benefit should not be underestimated, especially during long rehabilitation timelines.

The typical rehabilitation progression moves from passive movement (when the patient cannot move independently) to active-assistive movement (when some voluntary control returns) to fully active movement (when the patient can move through the full range under their own power). This progression is not always linear and may cycle between stages depending on pain levels, healing timelines, and daily fluctuations in the patient's condition.

10 Passive Movement Exercises by Joint

These exercises are commonly performed by physiotherapists, caregivers, or training partners. Each one should be performed slowly and gently, staying within the patient's pain-free range. Aim for 10 to 15 repetitions per direction, 2 to 3 times per day during the acute recovery phase. For a more extensive exercise list, see our guide on passive range of motion exercises for recovery.

Shoulder Passive Movements

1. Passive Shoulder Flexion The patient lies on their back with the arm resting at their side. The therapist supports the arm at the elbow and wrist, then slowly lifts it overhead in an arc toward the head, moving through the full available range. The arm is then lowered back to the starting position in a controlled manner.

Target range: Up to 180 degrees of flexion.

2. Passive Shoulder Abduction Starting from the same position, the therapist lifts the patient's arm out to the side, away from the body, keeping the palm facing upward. The movement continues until the arm reaches the available end range, then returns slowly.

Target range: Up to 180 degrees of abduction.

3. Passive External Rotation The patient lies on their back with the elbow bent to 90 degrees and tucked against the body. The therapist rotates the forearm outward (away from the body) while keeping the elbow stationary. This is particularly important after rotator cuff surgery or frozen shoulder treatment.

Target range: Up to 90 degrees of external rotation.

Elbow and Wrist Passive Movements

4. Passive Elbow Flexion and Extension The therapist supports the patient's upper arm and slowly bends the elbow, bringing the hand toward the shoulder (flexion), then straightens it fully (extension). This exercise is critical after elbow fractures, dislocations, or prolonged immobilization.

Target range: 0 degrees (full extension) to approximately 150 degrees (full flexion).

5. Passive Wrist Flexion and Extension The therapist stabilizes the patient's forearm and gently bends the wrist downward (flexion) and upward (extension). This is commonly used after wrist fractures, carpal tunnel release surgery, or repetitive strain injuries.

Target range: Approximately 80 degrees flexion and 70 degrees extension.

Hip Passive Movements

6. Passive Hip Flexion The patient lies on their back. The therapist supports the leg at the knee and ankle, then bends the hip by bringing the knee toward the chest. The opposite leg remains flat on the surface to stabilize the pelvis.

Target range: Up to 120 degrees of hip flexion.

7. Passive Hip Abduction From the same starting position, the therapist slides the patient's leg outward, away from the midline of the body, then returns it to center. This movement targets the inner thigh and hip joint capsule.

Target range: Up to 45 degrees of abduction.

Knee Passive Movements

8. Passive Knee Flexion and Extension The patient lies on their back. The therapist supports the leg at the ankle and behind the knee, then gently bends the knee by sliding the heel toward the buttock (flexion) and straightens it fully (extension). This is one of the most important exercises after total knee replacement surgery.

Target range: 0 degrees (full extension) to 130 to 140 degrees (full flexion).

Ankle and Foot Passive Movements

9. Passive Ankle Dorsiflexion and Plantarflexion The therapist supports the patient's lower leg and gently pushes the foot upward toward the shin (dorsiflexion) and downward away from the shin (plantarflexion). This exercise is essential after ankle sprains, fractures, Achilles tendon repairs, and prolonged bed rest.

Target range: Approximately 20 degrees dorsiflexion and 50 degrees plantarflexion.

10. Passive Ankle Inversion and Eversion The therapist stabilizes the lower leg and gently tilts the sole of the foot inward (inversion) and outward (eversion). This targets the subtalar joint and is important for restoring ankle stability after lateral ligament injuries.

Target range: Approximately 35 degrees inversion and 15 degrees eversion.

When Is Passive Movement Used?

Passive movement is not a one-size-fits-all treatment. Its application depends on the specific clinical situation, the stage of recovery, and the patient's ability to move independently.

Post-Surgical Recovery

After major joint surgeries such as total knee replacement, total hip replacement, ACL reconstruction, and rotator cuff repair, passive movement is typically introduced within the first 24 to 48 hours. The goal is to prevent the formation of adhesions and scar tissue within the joint while the surgical repair heals.

In the first 1 to 2 weeks post-surgery, passive movement is usually the primary form of joint mobilization. As healing progresses and pain decreases, the program transitions to active-assistive and then active exercises. The use of CPM machines in this phase varies by surgeon preference and current clinical guidelines.

Stroke and Neurological Rehabilitation

For patients who have experienced a stroke, spinal cord injury, traumatic brain injury, or other neurological events, passive movement serves a dual purpose. First, it maintains joint mobility in limbs that the patient cannot yet move voluntarily. Second, it provides sensory stimulation that may support neuroplasticity and the eventual return of motor function.

In stroke rehabilitation specifically, passive movement of the affected limbs helps manage spasticity (involuntary muscle tightness) by gently lengthening spastic muscles and maintaining soft tissue flexibility. This is often performed alongside activation exercises for the unaffected side and progresses toward active-assistive movements as motor control returns.

Injury Rehabilitation

Passive movement is a staple in the early rehabilitation of fractures (once appropriately stabilized), ligament sprains, muscle tears, and joint dislocations. It helps the injured area maintain mobility without placing stress on the healing tissues that active muscle contraction would produce.

For conditions like adhesive capsulitis (frozen shoulder), passive movement, including gentle stretching at the end range, is one of the primary treatment modalities used to gradually restore lost range of motion over weeks and months.

Contraindications and Precautions

While passive movement is generally safe, there are specific situations where it should be avoided, modified, or performed with extra caution.

Absolute Contraindications (do not perform):

Unstable or unhealed fractures at the joint being moved. Active joint infection (septic arthritis). Immediately following certain surgical procedures where the surgeon has restricted movement. Myositis ossificans (bone formation within muscle tissue). Disruption of the surgical repair site.

Relative Contraindications (proceed with caution):

Severe osteoporosis (risk of fracture with minimal force). Recent skin grafts or open wounds near the joint. Acute inflammation with significant swelling and heat. Hypermobility disorders where the joint already moves beyond normal range. Anticoagulant therapy (increased bleeding risk with aggressive movement).

General Precautions:

Always communicate with the patient about pain levels during passive movement. Stop immediately if the patient reports sharp, sudden, or worsening pain. Avoid pushing into ranges that have been restricted by the surgeon or treating physician. Document the range achieved in each session to track progress and identify complications early.

How to Progress from Passive to Active Movement

One of the most important aspects of rehabilitation is knowing when and how to progress from passive movement to independent, active movement. This progression is not arbitrary; it follows a logical sequence based on the patient's healing timeline, pain levels, and neuromuscular control.

Stage 1: Passive Movement (Weeks 1 to 3 post-injury or surgery) The therapist performs all movement. The patient focuses on relaxation and allowing full range of motion. The goal is maintaining mobility and preventing complications.

Progression criteria: Pain is manageable and decreasing. No signs of surgical complication or re-injury. Patient can tolerate the full available passive range without guarding.

Stage 2: Active-Assistive Movement (Weeks 2 to 6) The patient begins to contribute some muscular effort while the therapist assists through the range. Tools like pulleys, sliding boards, and therapy bands can help. The goal is rebuilding neuromuscular connections and reintroducing voluntary control.

Progression criteria: Patient can initiate the movement independently. Pain remains controlled. Range of motion is at least 70 to 80% of the uninjured side.

Stage 3: Active Movement (Weeks 4 to 8+) The patient performs the full range of motion independently without assistance. Resistance may be added gradually through bodyweight exercises, resistance bands, and eventually free weights. This stage connects rehabilitation to functional fitness and strength and conditioning training.

Progression criteria: Full active range of motion achieved. Pain-free movement through the entire range. Adequate strength to control the movement throughout.

Stage 4: Return to Functional Training The patient transitions from isolated joint exercises to compound, functional movements. This may include bilateral exercises, unilateral training, and sport-specific drills as part of a broader strength and conditioning program.

Note that these timelines are general guidelines. Individual progression depends on the specific injury, surgical procedure, patient age, and overall health status. A qualified physiotherapist should guide all progression decisions.

How Fitness Coaches Can Apply Passive Movement

Passive movement is not exclusively a clinical tool. Fitness coaches and personal trainers can incorporate passive movement principles into their programming, particularly for clients who are recovering from injuries, dealing with chronic stiffness, or working through mobility limitations.

Pre-workout mobility preparation: Gentle passive stretching of tight or restricted joints before a training session can improve range of motion and movement quality during the workout. This is particularly effective for clients with limited shoulder mobility, tight hip flexors, or restricted ankle dorsiflexion.

Post-workout recovery: Assisted passive stretching after a training session can help reduce muscle tension and promote relaxation. A trainer can gently move a client's limb through its range to facilitate a deeper stretch than the client might achieve alone.

Client assessment: Comparing a client's passive range of motion (how far the joint moves when you move it) to their active range of motion (how far they can move it themselves) reveals whether a mobility limitation is due to joint restriction or muscular weakness. If passive ROM is significantly greater than active ROM, the client needs strengthening in that range, not more stretching.

Working with rehab clients: Coaches who work with clients returning from physiotherapy can use passive movement as a warm-up protocol for the formerly injured area. This ensures the joint is mobile and lubricated before introducing load through exercises like GPP training movements or progressive resistance work.

Important boundary: Fitness coaches should not perform forced passive movement, treat acute injuries, or work outside their scope of practice. If a client presents with pain, significant restriction, or a recent surgical history, they should be referred to a qualified physiotherapist before passive movement techniques are applied.

Passive Movement for Specific Conditions

While passive movement is a universal rehabilitation tool, its application varies depending on the specific condition being treated. Here are some of the most common clinical scenarios.

Total Knee Replacement (TKR) After total knee replacement, passive knee flexion and extension are introduced within the first 24 hours in most modern protocols. The initial target is achieving 90 degrees of flexion within the first 1 to 2 weeks, with a long-term goal of 120 to 130 degrees. CPM machines are sometimes used in this phase, though their routine use has become less common as research favors early active mobilization combined with physiotherapy. Passive movement remains critical for patients who struggle to achieve adequate flexion independently.

Frozen Shoulder (Adhesive Capsulitis) Frozen shoulder is characterized by progressive loss of both active and passive range of motion due to thickening and contraction of the joint capsule. Passive movement, particularly gentle sustained stretching at end range, is one of the primary treatments. External rotation is usually the most restricted motion and requires the most attention. Treatment timelines are long, often 6 to 18 months, and patience with gradual passive movement is essential.

Stroke Rehabilitation In stroke patients with hemiplegia (paralysis on one side), passive movement of the affected limbs may be the only form of joint mobilization available in the early weeks. It helps manage spasticity, prevents painful shoulder subluxation, maintains hip and knee flexibility for future standing and walking, and provides the sensory input that supports neuroplasticity. As motor recovery progresses, the program shifts toward active-assistive and active exercises, but passive movement often remains a component of the daily routine for months or years.

Spinal Cord Injury Patients with complete spinal cord injuries lose all voluntary movement below the level of injury. Passive movement of the lower extremities (hips, knees, and ankles) is performed daily to prevent contractures, maintain tissue health, and support circulatory function. For these patients, passive movement may be a lifelong practice, performed by caregivers or with mechanical assistance.

Arthritis (Osteoarthritis and Rheumatoid Arthritis) For patients with arthritis, passive movement helps maintain joint mobility during flare-ups when active movement is too painful. Gentle passive range of motion through pain-free arcs reduces stiffness, promotes synovial fluid circulation, and keeps the joint from losing further mobility. Once the flare subsides, the program transitions back to active exercises and functional strengthening as part of a broader strength endurance program.

The Bottom Line

Passive movement is one of the foundational tools in rehabilitation and recovery. It keeps joints mobile when the body cannot move them independently, prevents the complications of immobilization, supports tissue healing through improved circulation, and provides the sensory input that the nervous system needs to maintain its connection to the affected area.

Understanding the three types of passive movement (relaxed, forced, and CPM), knowing when each is appropriate, and recognizing the contraindications ensures that passive movement is applied safely and effectively. The progression from passive to active-assistive to fully active movement is the roadmap that guides patients from the treatment table back to functional independence.

For fitness coaches, passive movement bridges the gap between clinical rehab and performance training. Knowing how to assess passive vs active range of motion, when to refer to a physiotherapist, and how to incorporate gentle passive techniques into your programming makes you a more effective and well-rounded professional.

Whether you are recovering from surgery, supporting a client through rehab, or simply looking to improve joint health, passive movement deserves a place in your toolkit.
