Chi Swing Machines
Our line of chi swing machines offers an accessible form of passive exercise, stimulating muscle contractions, boosting oxygen in the blood, and loosening the spine for greater overall health. They are used by chiropractors, massage therapists, and as a part of holistic healing practices.
USJ-815
Vitality Swing – USJ-815 (Passive Motion Therapy Device)
The Vitality Swing USJ-815 is a passive motion therapeutic device designed for individuals who require non–weight-bearing mobilization of the lower extremities and lumbar region. It is commonly incorporated into clinical care plans for patients with limited mobility or chronic musculoskeletal discomfort who may benefit from controlled passive movement.
This device features a 40-watt motor and padded vinyl ankle cradles to support stable positioning during use. The integrated remote control allows for speed adjustments without changing body position, and the 15-minute automatic shut-off timer provides consistent session duration.
Therapeutic Motion
The USJ-815 delivers controlled lateral oscillation of the lower limbs, which may be used as part of a supervised therapeutic program to assist with:
Maintenance of lower-limb circulation in individuals with restricted mobility
Reduction of stiffness in the lumbar and pelvic areas
Gentle mobilization when active exercise is limited or not tolerated
Adjunctive support in non-pharmacological management of chronic musculoskeletal or neuromuscular symptoms
Use Method:
The user positions their ankles in the padded cradles while lying in a supine position.
The device is activated using the remote control to initiate controlled passive motion.
Session intensity and duration are adjusted in accordance with clinical guidance.
The passive oscillatory movement may help support joint mobility and localized circulation as part of structured care for individuals who experience chronic discomfort or functional limitations.
Key Features:
• Gentle passive motion
• Supports circulation and mobility
• Variable speed adjustment
• Automatic 15-minute shut-off
• Remote control for easy operation
USJ-201
Swing Master – USJ-201 (Medical Use Version)
The Swing Master USJ-201 is a passive motion therapeutic device designed to assist in the management of chronic musculoskeletal symptoms under the guidance of a licensed healthcare provider. It features a durable 15-watt motor and padded vinyl ankle cradles to maintain stable positioning during therapy sessions. A remote control allows for speed adjustments without altering body position, and the unit includes variable speed settings and an automatic 15-minute shut-off timer for safety and dosage control.
This device provides controlled passive lateral oscillation of the lower extremities, a modality sometimes incorporated by clinicians into care plans for patients who require:
Improved lower-limb circulation due to limited mobility
Reduction of muscle stiffness and lower-back tension
Non-weight-bearing mobilization of the lumbar and pelvic regions
Support in managing chronic neuromuscular discomfort, including conditions such as Fibromyalgia, peripheral muscle hypersensitivity, or chronic low-back symptoms
Adjunctive therapy when active exercise is not tolerated
Passive motion therapy is commonly used in non-pharmacological management plans to help maintain joint mobility, promote blood flow, and reduce symptom severity in individuals who experience mobility limitations or chronic musculoskeletal pain disorders.
How Passive Motion Supports Key Physiological Functions
Sedentary lifestyles, long commuting hours, aging, and limited mobility can contribute to reduced circulation, fluid retention, stiffness, and lower-extremity discomfort. These factors are widely recognized as contributors to:
• Dependent edema (fluid buildup in the legs)
• Poor venous return
• Reduced lymphatic flow
• Joint and muscle stiffness from immobility
• Discomfort from prolonged sitting
Passive motion devices gently support these functions by providing consistent rhythmic movement without requiring active muscle engagement.
Common Use Cases for Passive Motion Devices
These devices are often incorporated into daily routines for individuals experiencing:
• Limited mobility or reduced ability to exercise
• Lower-extremity circulation challenges
• Lymphatic flow and fluid movement needs
• Mild swelling or fluid retention
• Discomfort from long periods of sitting, driving, or desk work
Why Passive Motion Is Recognized for Health Support
Rhythmic passive movement is commonly used to:
• Encourage venous return
• Promote lymphatic flow
• Reduce stiffness from inactivity
• Support lower-body comfort and mobility
• Help muscles relax after prolonged sitting
Note: These devices do not diagnose, treat, or cure any medical condition. They provide supportive motion for mobility and circulation wellness.
Swing Master USJ-201

Accessible Exercise for everyone
Even people with disabling injuries, chronic pain, or an inability to exercise can use one of our chi swing machines with ease.
To use, sit on the ground and place your feet on the comfortable ankle pads. Lie back in a relaxing position.
Turn on the machine and control its speed using the convienient remote control.
The wave-like motion of the legs moves up the body into the spine, the neck, and the shoulders, similar to the way that the bodies of fish move to oxygenate their blood.
Chi For Your Health
The gentle movement of the spine that results from using the machine encourages flexibility, heals the nervous system, and provides a powerful lymphatic massage.
In traditional Eastern medicine, chi represents the energy flow of the body, and therapeutic techniques often involve focused movements on parts of the body that help to unblock the flow of energy.
Chi swing machines are used by people with chronic muscle and nerve pain such as Fibromyalgia, since it stimulates circulation and helps to bring balance to the flow of energy throughout the body.
While using the machine, practice techniques to relax the mind and encourage deep breathing, and you will feel revitalized and invigorated when the session is complete. In fact, users often experience an incredible rush of energy once they turn off the machine.
Encourages Lymphatic Flow
Chi swing machines stimulate the lymphatic system, which is responsible for clearing excess fluids from the body. Research has shown that chi swing devices are an effective at-home adjunct therapy for patients who have experienced a decline in their lymphatic system (lymphoedema). This condition can develop alongside of other health problems and causes a buildup in fluids, usually to the legs and feet.
A 2004 study in the journal Lymphology demonstrated that regular at-home use of the chi swing resulted in less fluid buildup in the legs.
Body Manipulation for Spine and Hips
Our chi swing machines mimic a technique in massage therapy and body work in which the therapist grabs the ankles while the patient is lying on his or her back, and shakes them vigorously from side-to-side. This technique helps to loosen muscles that run along the entire length of the body, and when combined with breathing techniques can achieve a relaxation of the mind and body.
