A Plantarflexed 1st Metatarsal can Significantly Attenuate (distort downward) the PMS Values
Proprioceptive STimulation. An Effective Therapeutic Tool in Resolving Chronic Pain
by Correcting Postural Distortions (Poor Posture)
Prof/Dr Rothbart's Site for Health Care Researchers
Gravity forces the Primus Metatarsus Supinatus foot to abnormally pronate until the 1st metatarsal and hallux rest on the ground. Bracers compensate by plantarflexing the 1st metatarsal (recruiting the posterior tibialis and peroneus longus muscles). Releasers compensate by collapsing the entire medial column of the foot.
In bracers, tactile stimulation slowly reverses hypertonicity. This allows 1st metatarsal and hallux to shift back toward their anatomical neutral position. Clinically, this is reflected in the attenuated PMs values (see model, left).

Prof Rothbart presents his research on the Proprioceptive Loop (foot to brain connection), its impact on posture and the Primus Metatarus Supinatus foot type, in workshops all across Europe. For more information contact him at: rothbartsfoot@Yahoo.com
