QB1 Muscle Activation System now available for the treatment of quadriceps muscle atrophy.
The CyMedica QB1 is a knee brace with a built-in neuromuscular electrical stimulator that uses high intensity signals to activate the muscle, but without the discomfort that would be expected from such an approach, according to the company.
The system relies on closed-loop monitoring to regularly adapt the intensity of the signal to the requirements and comfort of the patient. A wired remote helps set and adjust various parameters of the QB1.

Professional athlete rehabilitation for every patient
The QB1 capitalizes on proprietary NMES (neuromuscular electrical stimulation) technology for the treatment of quadriceps muscle atrophy and combines three best-in-class products: a postoperative knee brace, a form-fitting conductive garment, and a user friendly NMES control interface. The device substantially simplifies the delivery of “at home” NMES treatment and encourages patient compliance.
“The CyMedica QB1 knee brace and wrap is a game changer in orthopedics,” says Dr. Struan Coleman, CyMedica cofounder, specialist in sports medicine at the Hospital for Special Surgery and NY Mets Head Team Physician. “The QB1 will allow the orthopedic surgeon to treat every patient like a professional athlete by initiating neuromuscular activation immediately following knee surgery. For the first time, the patient, the surgeon and the physical therapist will all be equally involved in postoperative rehabilitation of the knee.”
The QB1 NMES system delivers high intensity electrical muscle stimulation while maintaining patient comfort. The QB1’s proprietary, closed-loop system monitors and adjusts the electrical stimulation power delivered to the patient to ensure consistent and comfortable quadriceps activation.

The QB1 NMES and TENS systems are prescription devices in the USA and are intended to be used following the directions of a healthcare provider. The device may be used in a healthcare facility setting or by a patient or lay operator in a home environment.
The intended use of QB1 NMES device, including any indications for use, is limited to use in rehabilitation, including providing adjunctive therapy in rehabilitation for medical purposes.
Indications for Use
As a NMES device – Neuromuscular electrical stimulation, indications are for the following conditions:
- Relaxation of muscle spasms
- Retardation or prevention of disuse atrophy
- Increasing local blood circulation
- Re-educating muscles
- Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis
- Maintaining or increasing range of motion
The QB1 TENS device is intended for pain relief. As a TENS device – Transcutaneous electrical nerve stimulation, indications are for the following conditions:
- Symptomatic relief and management of chronic intractable pain
- Adjunctive treatment for post-surgical and post-trauma acute pain
