Passive movements in physiotherapy are joint and limb movements performed entirely by an external force, such as a physiotherapist’s hands, a caregiver, or a mechanical device, while the patient remains completely relaxed with no voluntary muscle contraction. The defining feature is the absence of effort: the muscles around the joint do no work, and the movement is guided slowly and smoothly within the available pain-free range. Passive movement is used to keep joints mobile when a patient cannot move them independently, to prevent stiffness and contracture during immobilization, and to restore range in the early stages of recovery from surgery or injury. This article covers what passive movement involves, the three recognized types, how it differs from active and active-assisted movement, where it sits in a rehabilitation progression, what it can and cannot achieve, how caregivers can apply it safely at home, and what the research says about machine-delivered passive motion.

What Are Passive Movements in Physiotherapy

Passive movements are movements of a joint or limb produced entirely by an outside force while the patient’s own muscles stay completely relaxed. If the patient is helping at all, the movement is no longer passive.

No longer passive matters clinically, because the purpose of the technique depends on the relaxation. A relaxed limb lets the practitioner feel exactly what the joint and surrounding tissue are doing, assess where the movement stops and why, and take the joint to the end of its available range without the patient’s protective guarding interfering.

Protective guarding is the usual obstacle, and much of the skill in delivering passive movement lies in producing enough confidence for the patient to release it. In physiotherapy this is a foundational technique rather than an occasional add-on, since assessment of passive range is part of almost every musculoskeletal examination we perform.

What Is an Example of Passive Movement?

A clear example of passive movement is a physiotherapist lifting and lowering a patient’s arm through shoulder flexion while the patient lets the arm go completely heavy. The therapist supplies all the force; the patient supplies none.

Supplying none of the force is what distinguishes it from the exercises patients are usually given. Everyday clinical examples include:

A therapist bending and straightening a knee after surgery while the patient lies relaxed. A caregiver moving a paralyzed limb through its range each morning. A patient using their good arm to lift the affected arm overhead, which is still passive for the affected side because its own muscles are doing nothing. A continuous passive motion machine cycling a knee through a preset arc. And joint mobilization, where a physiotherapist applies small graded movements to a stiff joint.

Joint mobilization is the version most patients receive in a clinic without realizing it has a name, and it belongs to a specific category within the passive family.

What Are the Three Types of Passive Movement?

The three types of passive movement are relaxed passive movements, forced passive movements, and accessory movements. They differ by how far into the range the practitioner goes and by whether the movement is one a person could produce voluntarily at all.

Relaxed passive movements are smooth, rhythmic movements taken through the available range without pushing into resistance, used to maintain mobility and encourage circulation. Forced passive movements are taken to the very end of a restricted range, applying gentle pressure against the barrier to increase it, and are used cautiously because pushing too hard provokes guarding and can aggravate tissue. Accessory movements are small joint glides and rotations that a person cannot perform on their own.

The table below places all three within the wider spectrum of movement types used in rehabilitation.

Type	Who produces the movement	Patient effort	Typical use	Example
Relaxed passive	Therapist, caregiver, or machine	None	Maintaining mobility, preventing stiffness	Moving a paralyzed leg through its range daily
Forced passive	Therapist, with gentle overpressure	None	Increasing a restricted range	Taking a stiff shoulder to its end range and easing further
Accessory	Therapist only	None, and not voluntarily possible	Restoring normal joint mechanics	Gliding the head of the humerus within the shoulder socket
Active-assisted	Patient with help	Partial	Transitioning toward independent movement	Lifting an arm with the therapist supporting its weight
Active	Patient alone	Full, unloaded	Restoring voluntary control	Raising an arm overhead without help
Resisted	Patient against load	Full, against resistance	Building strength and capacity	Shoulder press with a band or weight

The first three rows are passive; the last three are not. Accessory movement is the row most people have never heard of, and it is the one that explains what a physiotherapist is actually doing during hands-on treatment.

What Are Accessory Movements in Physiotherapy?

Accessory movements are the small gliding, rolling, and spinning motions that occur inside a joint during normal movement, which a person cannot produce voluntarily and which a physiotherapist produces by hand. They are the mechanical basis of joint mobilization.

Joint mobilization works because normal joint motion is not a simple hinge. When you raise your arm, the head of the humerus glides downward within the socket at the same time as the arm swings upward. When the knee bends, the femur rolls and glides on the tibia simultaneously. Lose the glide, and the swing becomes restricted or painful even though the muscles are working perfectly well.

Perfectly working muscles with a restricted joint is exactly the presentation that responds to manual therapy, since no amount of stretching or strengthening restores a glide that has been lost. The practitioner applies graded pressure in the direction of the restriction, feeling the quality of resistance at the end of range to identify which tissue is responsible. That is a fundamentally different activity from what the patient does in their own exercises.

What Are Active and Passive Movements in Physiotherapy?

Active movement is produced by the patient’s own muscles, while passive movement is produced entirely by an external force with the patient relaxed. The difference is who is generating the force, and it determines what each achieves.

What each achieves differs substantially. Passive movement maintains joint range, preserves tissue length, encourages circulation, and gives the practitioner assessment information. Active movement does all of that and additionally trains the nervous system to recruit muscle, builds strength, and develops the capacity that prevents recurrence.

Preventing recurrence is why active work eventually dominates every plan, and why the two are complements rather than alternatives. A patient two days after knee surgery may be entirely passive; the same patient at eight weeks should be almost entirely active. Between those two states sits a middle category that patients rarely hear named.

What Is Active-Assisted Movement?

Active-assisted movement is movement the patient initiates and contributes to, with a therapist, a caregiver, or the patient’s other limb supplying the remainder of the force. It is the bridge between passive and active.

The bridge exists because most recoveries do not jump straight from no muscle activity to full independent movement. A patient who cannot lift an arm against gravity can often lift it with some of its weight supported, which lets the muscle work at a level it can actually manage while the nervous system relearns the pattern.

Relearning the pattern is the point, and the amount of assistance reduces as capability returns. Together these categories form a sequence that describes most rehabilitation.

How Rehabilitation Progresses From Passive to Active

Rehabilitation typically progresses through four stages: passive movement, then active-assisted movement, then active movement, then resisted movement against load. Each stage prepares the tissue and the nervous system for the next.

The sequence generally runs as follows:

1. Passive movement. Used when the patient cannot move the joint safely or at all, to maintain range and prevent stiffness while healing begins.
2. Active-assisted movement. Introduced once some voluntary activation returns, with support reducing as control improves.
3. Active movement. The patient moves the joint independently through range without external help, restoring control and endurance.
4. Resisted movement. Progressive load is added through bands, weights, or body weight to rebuild strength and tolerance.
5. Functional loading. The movement is trained in the tasks it is actually needed for, whether that is stairs, lifting, or sport.

Getting to functional loading is the goal of every plan, and structured exercise rehabilitation is what carries a patient through the last three stages. The progression also explains why passive work alone leaves a recovery incomplete.

Do Passive Movements Build Strength?

Passive movements do not build strength, because muscle only adapts when it contracts against load, and passive movement involves no contraction at all. What passive work does is preserve the range and tissue condition that strength training later needs.

Preserving conditions is a genuine and valuable job. A joint that has kept its range through a period of immobilization is ready to begin loading as soon as it is safe; a joint that has stiffened into contracture needs weeks of work before strengthening can even start. Passive movement protects the starting position rather than improving on it.

Improving on it requires the patient’s own muscles to work, which is why strength training becomes the centre of the plan as soon as the tissue tolerates it. A treatment plan that stays passive indefinitely is a plan that has stalled, whatever the patient’s short-term comfort. Within its proper role, some passive techniques are more useful than others.

What Are the Best Passive Exercises?

The most useful passive techniques are joint mobilization for restricted joints, passive range of motion through the full available arc for immobilized limbs, sustained passive stretch for shortened tissue, and gentle rhythmic movement for painful or guarded joints. Which is best depends entirely on why the joint is not moving.

Why the joint is not moving is the assessment question that dictates everything. A joint restricted by capsular tightness responds to mobilization; a limb restricted by muscle shortening responds to sustained passive stretch; a limb restricted by pain and guarding responds to slow rhythmic movement well within the comfortable range rather than to anything forceful.

Anything forceful applied to a guarded limb produces more guarding, which is the most common error in passive work. Soft tissue restriction is often addressed alongside joint work, with massage therapy handling the muscular component while physiotherapy addresses the joint itself. The shoulder is the joint patients ask about most.

What Are Some Passive Stretches for the Shoulders?

Common passive shoulder techniques include therapist-guided shoulder flexion and abduction, passive external and internal rotation with the elbow supported, table slides, and pendulum-style movements where the arm hangs and is moved by body sway rather than by shoulder muscles. All keep the shoulder muscles inactive.

Inactive shoulder muscles are harder to achieve than they sound, since the shoulder guards readily. Supporting the elbow and forearm fully, moving slowly, and staying within a comfortable arc all help the patient release. Rotation techniques are usually performed lying down with the arm supported on a pillow, because the position removes the need to hold anything.

Holding nothing is the principle behind table slides too, where the forearm rests on a smooth surface and the body moves rather than the arm. These techniques are frequently prescribed after shoulder surgery or during the painful phase of a frozen shoulder, and they should be taught by a physiotherapist before being practised at home. Another population relies on passive work heavily.

What Are Good Range of Motion Exercises for Seniors?

Useful range of motion work for older adults covers the major joints in turn: ankle circles and pumps, knee bends, hip flexion and rotation, shoulder flexion and rotation, elbow bending, wrist circles, and gentle neck movements. Each joint is moved slowly through its comfortable range several times.

Comfortable range is the operative limit, since older tissue tolerates less force and skin is more fragile. Where an older adult can perform the movements themselves, active range of motion is preferable because it maintains muscle activity as well as joint mobility. Passive assistance is added only for joints they cannot move independently.

Joints they cannot move independently are commonly in the shoulder and hip. Lower limb mobility work also connects to walking and balance, and where gait mechanics or foot posture are contributing to stiffness and discomfort, custom orthotics address a structural factor that movement alone cannot change. Much of this work happens between appointments.

Can Family Members Perform Passive Movements at Home?

Family members and caregivers can perform passive movements at home, and often need to, but they should be taught the specific techniques by a physiotherapist first, particularly after a stroke, surgery, or spinal injury. The technique looks simple and is easy to do badly.

Doing it badly means moving too fast, pushing past comfort, gripping the limb in ways that compress tissue, or moving a joint in a direction that has been restricted by a surgeon. Basic safety rules for caregivers:

• Get taught first. A physiotherapist should demonstrate each movement, watch you perform it, and confirm which joints and directions are safe.
• Support the limb above and below the joint. Never move a joint by holding only the far end of the limb.
• Move slowly and smoothly. No jerking, bouncing, or momentum.
• Stay within comfort. Stop at the first sign of pain or resistance unless specifically instructed otherwise.
• Watch the face, not just the limb. Patients who cannot speak may show discomfort only in their expression.
• Respect surgical restrictions. Post-operative protocols often prohibit specific directions for weeks.
• Stop and report changes. New pain, swelling, warmth, or reduced range should be reported before the next session.

Reporting changes matters because a caregiver often notices a problem days before the next appointment. Our physiotherapists routinely teach family members the specific movements a patient needs, which is a far better use of an appointment than performing them once a week ourselves. Frequency is the next question caregivers ask.

How Often Should Passive Range of Motion Exercises Be Done?

Passive range of motion exercises are typically performed once or twice daily, with each joint moved through its range five to ten times, though frequency depends on the condition and on any surgical protocol. Daily consistency matters more than session length.

Session length is short by design: a full body routine covering the major joints usually takes ten to fifteen minutes. Immobilized or paralyzed limbs generally need daily attention to prevent contracture, while a post-surgical joint follows whatever schedule the surgical protocol specifies, which can be several short sessions a day in the early phase.

Early phase protocols are also where machines enter the picture, since a device can deliver far more repetitions than a person reasonably can. Whether that translates into better outcomes is a fair question.

Do CPM Machines Work After Knee Replacement?

The evidence for continuous passive motion machines after knee replacement is weaker than their long-standing popularity suggests, with recent reviews finding little meaningful benefit for range of motion or function over standard physiotherapy. They have been in routine use since the early 1980s.

Routine use has outlasted the evidence supporting it. A systematic review and meta-analysis of 16 studies found that continuous passive motion did not significantly improve postoperative knee range of motion or functional outcomes, did not reduce length of stay, and did not reduce adverse events, concluding that the available evidence was insufficient to support routine clinical use. A meta-analysis of six articles covering 557 patients found passive knee flexion outcomes essentially similar between machine-delivered motion and standard physical therapy. A separate Cochrane review of 11 trials involving 808 participants found insufficient evidence that the machines reduce venous thromboembolism after surgery.

The picture is not entirely one-sided. A Cochrane review did find that short-term use produced greater short-term range of motion gains, and a meta-analysis of seven randomized trials involving 501 patients has compared machine-delivered passive motion against continuous active motion. The reasonable reading is that the machine is a convenience that delivers repetitions rather than a treatment that changes outcomes, and that hands-on work plus early active exercise is where the benefit actually sits. Where post-surgical pain is limiting early movement, adjuncts such as acupuncture are sometimes used to make that early work tolerable.

When Should Passive Movement Not Be Used?

Passive movement should not be applied over an unstable fracture, a recently repaired tendon or ligament outside its protocol, an acutely inflamed or infected joint, a suspected deep vein thrombosis, or any joint where a surgeon has specified movement restrictions. Each of these can be made substantially worse by well-intentioned movement.

Well-intentioned movement causes most of the harm in this area, because passive techniques feel gentle and the patient cannot always report pain. Additional caution applies with osteoporosis, where bone is fragile, with heterotopic ossification, where new bone forms in soft tissue, and with joints that have recently dislocated, where certain directions risk repeating the event.

Repeating the event is avoided by knowing the protocol, which is why passive work after surgery should follow the surgeon’s specific instructions rather than a general routine. Where restriction involves the spine or several linked joints, coordinated chiropractic care and physiotherapy assessment help clarify what is safe to move and in which direction. One terminology point regularly causes confusion.

What Is an Example of a Passive Physical Activity?

Passive physical activity in the everyday sense means sedentary behaviour such as sitting or lying still, which is entirely different from clinical passive movement, where a joint is deliberately moved by an external force. One is the absence of movement; the other is movement without effort.

Movement without effort is the clinical meaning, and conflating the two leads patients to assume passive treatment is the same as doing nothing. It is not: a limb moved through its full range twice daily is receiving mechanical input that a limb left still is not, and that input is what prevents contracture.

Preventing contracture is a concrete outcome, not a placeholder activity. That said, passive treatment is a stage rather than a destination, which brings us to how long it lasts.

How Long Does Treatment Take to Progress From Passive to Active?

Most patients move from passive to active-assisted movement within one to three weeks and to fully active movement within four to eight weeks, though neurological conditions and complex surgeries can take considerably longer. Progression is governed by tissue healing and by the return of voluntary control rather than by the calendar.

The calendar matters less than the milestones. A post-surgical patient progresses when the surgeon’s protocol allows it and when the muscle can activate against gravity. A patient after a stroke progresses as motor control returns, which follows its own timeline. A patient with a stiff shoulder progresses as the joint releases.

Releasing a joint, restoring control, and rebuilding capacity are three different projects, and our full range of rehabilitation services exists partly so that a plan can shift between them as the presentation changes. Physiotherapy in Markham at our clinic means reassessing on a schedule so the progression happens when the patient is ready rather than when the calendar says so.

Frequently Asked Questions

Are Joint Mobilizations the Same as Passive Movements?

Joint mobilizations are a form of passive movement, specifically the accessory movement type, where a physiotherapist applies small graded glides to a joint that a patient cannot produce voluntarily. All mobilizations are passive, but not all passive movement is mobilization. Moving a limb through its full range is passive movement; gliding one joint surface on another is mobilization.

Does Passive Movement Hurt?

Passive movement should not hurt, since it is guided within the available pain-free range and the patient’s muscles are relaxed. Mild stretching sensation at the end of range is normal, particularly with forced passive technique. Sharp pain, or pain that lingers after the session, means the technique or the range needs adjusting and should be reported.

Can Passive Movement Help After a Stroke?

Passive movement is widely used after a stroke to maintain joint range and reduce the risk of contracture in limbs that cannot yet be moved voluntarily. It does not restore motor control on its own, which comes from active and task-specific practice as recovery allows. Stroke rehabilitation is a specialized area, and treatment should be directed by a team experienced in neurological rehabilitation.

Is Stretching a Passive or Active Exercise?

Stretching can be either. A stretch held by a therapist or by the opposite limb, with the target muscle relaxed, is passive. A stretch the patient holds by contracting opposing muscles is active. Most stretches performed in a clinic are passive, while many done independently are a combination of the two.

Who Can Perform Passive Mobilization in Ontario?

Passive movement and joint mobilization are performed by physiotherapists, chiropractors, and other regulated health professionals trained and competent in the techniques, working within their own scope of practice. Physiotherapists in Ontario are regulated by the College of Physiotherapists of Ontario, and the public register is searchable by name. Caregivers can perform basic passive range of motion at home once taught by a qualified practitioner.

The Bottom Line

Passive movements in physiotherapy are movements produced entirely by an external force while the patient stays relaxed, and they come in three forms: relaxed passive movement through the available range, forced passive movement into a restricted end range, and accessory movement, the small joint glides that only a practitioner can produce and that underpin manual therapy. Their job is to maintain joint range, prevent contracture, encourage circulation, and give the practitioner information about which tissue is limiting movement. What they cannot do is build strength, because muscle only adapts when it contracts against load.

That limit is why passive work is a stage rather than a destination, with most recoveries moving through passive, then active-assisted, then active, then resisted movement as tissue heals and control returns. It is also why the evidence for machine-delivered passive motion after knee replacement is so underwhelming: repetitions alone do not produce the adaptation that active work does. At KC Rehab in Markham, passive techniques are used where they genuinely earn their place, and the plan moves toward active loading as soon as the tissue allows. If a stiff or painful joint could use that kind of attention, you are welcome to book an assessment.
