You’ve likely seen the circular marks on athletes’ shoulders and wondered what they mean. Those distinctive patterns result from cupping therapy, an evidence-based soft-tissue technique physical therapists use to reduce pain, improve mobility, and accelerate recovery.
In this article, you will learn what cupping is, how it works, the specific benefits supported by research, and how physical therapists use it as part of a larger rehabilitation plan.
What Is Cupping Therapy?
Cupping therapy is a manual treatment technique that uses negative pressure to lift soft tissue away from underlying structures.
This decompression releases fascial restrictions, improves blood flow, and reduces tissue stiffness. Physical therapy clinics almost exclusively use dry cupping, a noninvasive approach that involves placing cups on the skin without making incisions or drawing blood.
What Is Cupping Therapy?
Cupping therapy is a manual treatment technique in which specialized cups create negative pressure that gently lifts soft tissue away from underlying structures. Research using quantified negative-pressure devices has shown that cupping
increases soft-tissue elevation and alters mechanical tension, supporting the idea that it decompresses rather than compresses tissue.
This decompressive effect also influences local circulation. Studies demonstrate that cupping
can significantly increase skin blood flow, particularly at higher negative pressures. Additional research shows that negative pressure can reduce muscle stiffness and improve tissue compliance, potentially allowing tissues to move more freely.
In rehabilitation settings, physical therapy clinics almost exclusively use
dry cupping, a noninvasive technique in which suction is applied without incisions
or blood removal. Clinical reviews confirm that dry cupping is the standard method used in
evidence-based musculoskeletal practice.
Types of Cupping
- Dry cupping – The standard method used in physical therapy. Suction is created through manual pumps or silicone cups to decompress tissue and improve mobility.
- Fire cupping – Often used in traditional alternative medicine settings, this technique heats the air inside a glass cup, then places it on the skin to create suction.
- Wet cupping – Involves making small incisions to draw blood. This method is not used in licensed medical or physical therapy environments.
How Cupping Differs from Massage
Unlike massage, which compresses tissue downward, cupping creates negative pressure that lifts and decompresses.
This lifting effect allows fascia to separate, improves blood flow, and facilitates the removal of metabolic waste, making it particularly effective for releasing deep fascial adhesions that compression techniques may not reach.
How Cupping Works in Physical Therapy
At a physical therapy clinic, cupping is rarely used in isolation. It’s combined with movement, stretching, manual therapy, and strengthening exercises to create long-lasting functional improvements. This integrated approach distinguishes therapeutic cupping from passive treatment methods. Below are some mechanisms supported by current evidence:
Increased local blood flow
The suction effect enhances circulation in superficial soft tissues, delivering oxygen and nutrients while helping remove metabolic waste products. Research using laser Doppler flowmetry has demonstrated that cupping significantly increases skin blood flow.
Reduced muscle tone and guarding
Helps muscles relax and reduces protective tension, making movement feel easier and more comfortable. Decreased pain following cupping may result from inhibitory pain modulation that alters pain sensitivity.
Improved fascial glide
The negative pressure lifts and separates fascial layers, reducing friction between tissues. This is particularly helpful for people experiencing stiffness, tension, or mobility restrictions. Cupping increases tissue elasticity and improves tissue extensibility.
Modulation of the nervous system
Cupping has been shown to affect the nervous system, particularly by modulating pain perception. This can help reduce sensitivity in irritated tissues and promote the body’s natural healing response.
Improved lymphatic flow
Cupping stimulates the lymphatic system, aiding in drainage and helping reduce swelling. This supports recovery after activity or soft tissue irritation.
The Role of Cupping in Recovery
Cupping is not a primary standalone treatment for injury healing. Instead, it serves as a preparatory technique that makes tissues more receptive to exercise-based rehabilitation. Cupping helps create an optimal environment for therapeutic exercise. This helps patients be more comfortable by reducing tension, improving mobility, and decreasing pain sensitivity.
Key Benefits of Cupping Therapy
Cupping therapy offers several clinically recognized benefits, including pain reduction, improved mobility, and enhanced tissue health. Below are the benefits most commonly observed in physical therapy settings, supported by current research and patient outcomes.
1. Pain Reduction
One of the most widely reported effects of cupping is short-term pain relief. Research confirms that cupping is more effective in improving pain and functional disability in people with persistent low back pain compared to sham therapy, and a single session of dry cupping may provide immediate pain relief. The decompression forces created by the cups reduce tension in muscles and surrounding tissues, providing relief for the neck, upper back, lower back, shoulders, hips, and legs.
2. Improved Circulation
The suction from cupping draws blood toward the treated area, and research using laser Doppler flowmetry has demonstrated that cupping significantly increases skin blood flow. This improved circulation supports healing, decreases local stiffness, and is one of the clearest mechanisms confirmed in research on dry cupping.
3. Improved Range of Motion
Cupping therapy significantly improved hip joint range of motion in female professional soccer players, and dynamic cupping increased hamstring mobility in high-level athletes. Cupping often results in noticeable improvements in mobility by reducing stiffness and improving tissue glide. Physical therapists commonly use cups before stretching or exercise to prepare tissue for movement.
4. Reduced Muscle Tightness and Trigger Points
Cupping helps reduce the tight, rope-like areas commonly called “knots.” Many individuals experience significant relief from muscle tension and pain, particularly in areas that commonly hold stress and tightness. Trigger point regions respond well to lifting and decompression, with many patients reporting feeling lighter or looser after treatment.
5. Support for Recovery After Activity
Athletes and active individuals often experience soreness and tissue fatigue. Cupping can help address the demands of athletic performance and recovery by improving the flow of fluids in and around the muscles, reducing feelings of heaviness or tightness after workouts.
6. Calming Effect on the Nervous System
Cupping stimulates large nerve fibers that inhibit the transmission of pain signals to the brain via the dorsal horn of the spinal cord. Some patients report feeling relaxed during cupping, as the sensation and rhythmic suction can help stimulate the parasympathetic response, supporting relaxation and reducing baseline muscle tension.
7. Understanding the Marks
Cupping marks are not bruises but rather a therapeutic response indicating increased blood flow to the treated area. These circular marks result from blood being drawn toward the surface and typically fade within a few days to two weeks.
Conditions Cupping May Help With
Cupping is not a cure for any one condition, but it can support treatment for several musculoskeletal issues when used alongside exercise and manual therapy.
Common conditions treated with cupping at physical therapy clinics include:
- Back and neck pain
- Shoulder and scapular tension
- Hip and glute tension
- General muscle stiffness
- Rotator cuff tightness
- Chronic pain conditions involving muscular guarding
- Tendinopathies, when used alongside strengthening
- Movement restrictions after injury or surgery (as allowed by the care plan)
What Cupping Feels Like
During a cupping session, you’ll experience a gentle pulling or suction sensation as the cups draw your skin upward. This feeling should never be sharp or painful. Instead, most people describe it as a unique combination of pressure and stretch that ranges from light to moderately firm, depending on the suction strength used.
The experience is often surprisingly relaxing. While the cups create distinctive circular marks on the skin, these discolorations are typically painless and fade naturally within a few days to a week.
How Long Do the Benefits Last?
The duration of cupping’s effects varies based on individual factors, including your specific condition, overall health, and treatment frequency. Most people notice immediate relief that lasts 24 to 72 hours after a session.
However, these benefits can extend well beyond the short term. When cupping is incorporated into a comprehensive wellness routine that includes regular exercise, stretching, and mobility work, many people experience cumulative improvements that build over time. Consistent treatment sessions often lead to more sustained results as your body progressively responds to the therapy.
Is Cupping Safe?
When performed by a trained and licensed healthcare professional, cupping therapy is generally considered safe with minimal risk. Most adverse effects are mild to moderate, and serious complications are rare when proper techniques and hygiene standards are followed.
What to Expect After Treatment
The most common side effects of cupping are temporary and typically resolve on their own:
- Circular marks or bruising – These distinctive marks fade naturally within a few days to two weeks
- Temporary warmth in the treated area
- Mild skin sensitivity or tightness
- Occasional dizziness or lightheadedness – Usually preventable by staying hydrated and eating before treatment
Who Should Avoid Cupping
Certain medical conditions and situations make cupping therapy inadvisable. You should not receive cupping if you have:
- Bleeding disorders, such as hemophilia, or are taking blood-thinning medications (anticoagulants or antiplatelet drugs)
- Active skin infections, wounds, or skin ulcers in the treatment area
- Cancer, organ failure, or implanted medical devices like pacemakers
- Severe eczema or psoriasis that could worsen with treatment
- Recent sunburn or trauma to the skin
Special Considerations
Pregnancy: Certain areas, such as the lower abdomen and lower back, should not be cupped on pregnant women, though cupping may be safe in other areas when performed by an experienced practitioner.
Medications: Anticoagulants and antiplatelet agents significantly increase the chance of large bruises and prolonged bleeding, while steroids can thin the skin and increase fragility.
Cupping should not be applied directly over sensitive areas like veins, arteries, nerves, varicose veins, skin lesions, or inflamed areas.
Finding a Qualified Practitioner
Always seek treatment from a licensed healthcare professional, such as a physical therapist, licensed acupuncturist, or trained massage therapist who follows proper sterilization protocols. Before your first session, discuss your complete medical history and any medications you’re taking to ensure cupping is appropriate for your individual situation.
Dry Cupping vs. Wet Cupping
Understanding the distinction between dry and wet cupping is essential, as these two techniques differ significantly in their approach and application.
What is Dry Cupping?
Dry cupping is the most commonly used form of cupping therapy in the United States and is the standard technique employed in physical therapy clinics. This method involves placing specialized cups on the skin and creating suction using either a manual pump or a mechanical device; no incisions or blood removal are involved.
The suction created by dry cupping:
- Lifts and separates soft tissue
- Increases local blood circulation
- Provides a form of myofascial release and tissue decompression
- Helps relieve muscle tension and reduce inflammation
Physical therapists may apply the cups statically (leaving them in place for several minutes) or use a gliding technique with lotion to achieve a deep-tissue massage.
This noninvasive approach focuses entirely on soft-tissue mobilization and improving musculoskeletal function.
What is Wet Cupping?
Wet cupping involves creating small incisions in the skin before applying suction, which draws out small amounts of blood. This technique is rooted in traditional medicine practices and is associated with alternative medicine approaches focused on detoxification and bloodletting.
Research suggests that wet cupping may be particularly effective for inflammatory-related pain conditions, though it requires strict hygiene protocols due to blood involvement and carries safety considerations distinct from those of dry cupping.
Which Method Do Physical Therapy Clinics Use?
Physical therapy and licensed medical practices exclusively use dry cupping. This evidence-based, noninvasive technique aligns with modern rehabilitation principles and focuses on:
- Musculoskeletal pain relief
- Enhanced athletic recovery
- Improved range of motion
- Complementary treatment alongside exercise therapy and manual techniques
Wet cupping is not performed in physical therapy or mainstream medical settings. If you’re seeking cupping therapy as part of a comprehensive rehabilitation program, you’ll receive dry cupping, a safe, professional approach to soft-tissue treatment that avoids skin incisions.
How Physical Therapists Use Cupping in a Treatment Plan
At Calibration Physical Therapy, cupping is integrated into a comprehensive treatment plan focused on achieving long-term recovery and improved function. Unlike traditional passive cupping, physical therapists combine cupping with active movement to maximize therapeutic benefits and achieve lasting results.
A typical cupping session includes:
- Tissue assessment – Your therapist evaluates areas of tension, restricted mobility, or fascial adhesions to determine optimal cup placement
- Strategic cup placement – Cups are positioned on key regions based on muscular anatomy and your specific movement limitations
- Movement-based cupping – You perform active movements while cups remain in place, creating a decompressive effect that improves fascial glide and tissue mobility
- Follow-up manual therapy – Additional hands-on techniques complement the cupping treatment
- Strengthening and mobility exercises – Targeted exercises take advantage of newly improved tissue mobility to reinforce functional movement patterns
This integrated approach creates lasting improvements, as cupping is not performed in isolation but is combined with neuromuscular re-education and corrective exercises.
The goal is to optimize human movement and enhance your body’s natural healing capacity, not simply provide temporary symptom relief.
Frequently Asked Questions
If you’re considering cupping therapy as part of your physical therapy treatment, you likely have questions about how it works, what to expect, and whether it’s right for you. Here are answers to the most common questions we hear from patients.
Does cupping work?
Research indicates that cupping may have clinically meaningful short-term effects on pain and disability, particularly when combined with exercise and physical therapy techniques. Studies show moderate-quality evidence supporting cupping for chronic pain, knee osteoarthritis, low back pain, and neck pain. While the evidence quality ranges from low to moderate, cupping appears most effective when integrated into a comprehensive treatment approach.
How soon will I feel results?
Many people experience improvements immediately or within a few hours following treatment. Research demonstrates that cupping can significantly reduce sensory and emotional pain immediately, after 24 hours, and up to 2 weeks post-intervention. Individual responses vary based on the condition being treated and your body’s healing capacity.
How many sessions do I need?
The number of sessions depends on the severity and chronicity of your condition, as well as your treatment goals. Some people benefit from a single session, while chronic conditions may require multiple treatments over several weeks. Your physical therapist will create a personalized plan based on your specific needs and response to treatment.
Do the marks mean anything?
Cupping marks are not bruises but rather a therapeutic response indicating increased blood flow to the treated area. These marks are typically painless and differ from traumatic bruising. They represent the body’s natural healing response to improved circulation. The intensity of marks varies based on tissue congestion and individual factors, but they are not indicators of injury severity.
Can cupping help with chronic pain?
Cupping demonstrates superior, sustained pain reduction compared to medication and usual care for conditions such as low back pain. It may help reduce muscle guarding, tension, and sensitivity. However, the best long-term outcomes occur when cupping is consistently paired with appropriate exercise, manual therapy, and movement re-education.
