Mirror Box Therapy

Mirror Box Therapy (mirror therapy) uses a mirror placed in the midline so that movements of the unaffected limb appear as if they are movements of the affected limb. It is used to improve motor function after stroke and to reduce pain in complex regional pain syndrome (CRPS) and some other persistent pain states. The affected limb is typically hidden behind the mirror while the person watches the reflection of the healthy limb.

Overview

What It Is Mirror Box Therapy (mirror therapy) uses a mirror placed in the midline so that movements of the unaffected limb appear as if they are movements of the affected limb. It is used to improve motor function after stroke and to reduce pain in complex regional pain syndrome (CRPS) and some other persistent pain states. The affected limb is typically hidden behind the mirror while the person watches the reflection of the healthy limb.

How It Works Watching the reflection creates a visual illusion that the affected limb is moving normally. This visual input can activate motor and sensory networks linked to the affected side, helping to restore more accurate body maps and reduce learned non-use or pain-related protection. It is a practical application of visual-motor neuroplasticity and is often a component of Graded Motor Imagery programs.

Conditions - Established / commonly used for: upper-limb motor recovery after stroke; complex regional pain syndrome (especially post-stroke CRPS). - Also used for: phantom limb pain and selected other persistent pain or motor conditions. - Note: Moderate evidence from randomized trials supports benefits for motor function and pain in appropriate patients. Low cost and low risk.

How it is administered

Clinic and/or home practice. A mirror is placed in the sagittal plane; you move the unaffected limb while watching its reflection, keeping the affected limb hidden. Sessions often last 15–30 minutes, several times per week, for multiple weeks—alone or as part of broader rehab or Graded Motor Imagery.

The NPA Treatment Database lists this treatment in connection with 3 condition records. A database relationship does not establish effectiveness, safety, or suitability for an individual.

Practical information

Insurance coverage

Often covered when delivered as part of occupational or physical therapy for approved diagnoses.

Cost information

Very low for the mirror itself; therapy session costs follow standard PT/OT rates when clinician-guided.

Results and outcomes described in the source record

Motor and pain changes often assessed over 2–6 weeks of consistent practice.

Side effects and risks

Very low risk; temporary frustration or mild increased awareness of the affected limb possible.

Research context in the NPA database

This section reproduces the current database's research summary and detail. Structured citation metadata has not been supplied, so it should not be read as an independently verified literature review.

Research summary

Evidence Level: Moderate What the research shows: Multiple RCTs support mirror therapy for upper-limb motor recovery after stroke and for pain/motor outcomes in post-stroke CRPS. Effect sizes vary; best used as part of a broader therapy plan. Key takeaway: A simple, low-cost method with moderate evidence for stroke-related arm function and CRPS-related pain.

Research detail

Overview Mirror Box Therapy uses the visual illusion of normal movement of the affected limb (via reflection of the unaffected limb) to support motor recovery and pain reduction.

Evidence Base and Published Work • Randomized trials in stroke show improvements in upper-limb motor function when mirror therapy is added to conventional rehab. • RCTs in post-stroke CRPS report better pain and motor outcomes with mirror therapy versus control in several studies. • Mirror therapy is also a standard stage in Graded Motor Imagery protocols for persistent pain. • Reviews note variability in dose and methods; overall evidence is moderate.

Outcomes Outcomes most frequently described include improved arm/hand function after stroke and reduced pain with better function in CRPS when practice is consistent over several weeks.

Questions to ask a provider

1. Is mirror box therapy appropriate for my stroke-related arm weakness or CRPS pain? 2. How should I set up the mirror and what movements should I practice? 3. How many minutes per day and how many weeks of practice are recommended? 4. Should this be done only in therapy sessions, or also as a structured home program? 5. How will we measure improvement in movement or pain, and how does this fit with my other rehab?
