Firefly | Sports Recovery device for DOMS


The Science

The OnPulse™ Technology powering the firefly™ device is proven to increase blood circulation for the reduction of muscle soreness (DOMS) within 24 hours, to aid recovery from sprains and strains and to reduce swelling after injury and surgery. Read a selection of the scientific evidence behind neuromuscular electrostimulation and firefly™.

Study 1

Tucker et al

Augmentation of venous, arterial and microvascular blood supply in the leg by isometric neuromuscular stimulation via the peroneal nerve.

The use of OnPulse™ technology for neuromuscular electrostimulation of the muscles in the lower leg significantly increases blood flow and velocity back to the heart.


Study 2

Beaven et al

Electrostimulation’s enhancement of Recovery During a Rugby Preseason.

Electrostimulation produced both psychometric and physiological recovery benefits in professional male rugby players when combined with a lower-body compression garment.


Poster 1

Ferguson et al

Effect of neuromuscular electrostimulation via the peroneal nerve on one-legged peak oxygen uptake and peak power output following four weeks of high intensity intermittent training.

The use of firefly™ for NMES immediately after a training session did not have a detrimental effect on muscle adaptation.


Study 3

Ferguson et al

Neuromuscular electrical stimulation via the peroneal nerve is superior to graduated compression socks in reducing perceived muscle soreness following intense intermittent endurance exercise.

The use of firefly™ (NMES) is superior to compression socks in reducing perceived muscle soreness following intense intermittent endurance exercise.


Poster 2

Pelech et al

Comparing the effects of acupuncture with neuromuscular stimulation on short term lower limb blood flow; an observational study.

The firefly™ device considerably increased blood flow which could benefit training recovery and injury healing, without significantly increasing metabolic activity in the calf muscle.


Study 4

Taylor et al

The impact of neuromuscular electrical stimulation on recovery after intensive, muscle damaging, maximal speed training in professional team sports players.

The use of firefly™ (NMES) aids the physiological and psychological measures of recovery that can lead to significant increases in performance 24 hours post strenous exercise. firefly™ offers an easily applied recovery strategy which may have particular application during sleep and travel.


Case Study 1

Ben Dixon

Case Study: The use of Neuromuscular Electrostimulation during Rehabilitation Post Osteoarticular Transfer System Surgery in a Professional Football Player. 

This case study shows firefly™ (NMES) could play an important role in injury rehabilitation and an athlete’s return to play protocols.
