Once again I had pleasure traveling to sunny Poland in the first half of the May. Several hundred people were introduced to basic PRI concepts in Warszawa (Warsaw) and Poznań, as well as two courses were taught in Opole (Postural Respiration and Myokin Restoration). Food as usual was delicious and their infrastructure is continuously evolving. Traveling in southern Poland I have spotted these two bridges shown below. I think these bridges are the best representation of levator scapula action in physiological and compensatory state and its influence on cervical lordosis. Concomitant and reciprocal ideas between rehab medicine and engineering are getting stronger in Poland. ;)
