The Exercise Conundrum in Fibromyalgia and ME/CFS
Exercise is important for cardiovascular health, cognition, mood and pain relief but how to get the benefits of exercise without getting hammered has been one of the great questions for many people with FM, ME/CFS and allied disorders. When even mild activity can bring pain, how to get the blood flowing without producing a symptom flare?

Vital Motion may have found a way. Their Hummingbird machine triggers a reflex that gets the blood flowing in the lower and perhaps even the upper body – while you’re sitting down. It presents the possibility of getting some of the benefits of exercising while not actually exercising.
Instead of pounding away to get one’s blood flowing during what, to be honest, is going to be a very limited walk anyway (and is likely going to leave one in pain), Vital Motion’s Hummingbird device purports to gets the blood and fluids in your body moving without your ever leaving your chair.
Activating “The Second Heart”
The device – which one plugs in and then steps on with the front of your foot – produces a vibration detected by sensors on the front of foot called Meissner’s Corpuscles. This in turn activates something called the postural reflex arc at the front of the foot.
That reflex then stimulates the soleus muscle in the calf which plays an important enough role in our circulation as to sometimes be called “the second heart”. Activation of that soleus muscle returns pooled blood and interstitial fluid back into the circulatory system, increasing blood flow to the body and hopefully reducing symptoms.
Plantar stimulation may sound like science fiction, but the medical literature suggests it may work. Back in 2005,
plantar stimulation was shown to increase both peripheral and system circulation. Calf muscle pump stimulation substantially
improved sleep in one small study. It reversed the resting
tachycardia that eleven women experienced after 20 minutes of sitting. It’s been shown to increase blood flows in the legs, and it reversed the
blood pooling in the legs of almost 50% of women in one study.
The Hummingbird is somewhat similar to the Avacen 100 device developed for fibromyalgia which uses microprocessors and heat to enhance microcirculation of the hands and hopefully the rest of the body. Both machines attempt to improve the circulation, increase oxygen delivery, reduce sympathetic nervous system activation and relieve pain.
