There are plenty of smaller muscles underneath the plantar surface of the foot and in all probability due to their dimension they have not been given much importance. This has begun to change recently as research has begun to indicate precisely how critical those muscles are to natural function and biomechanics of the foot. They appear to perform a pretty important roll in how we balance and issues with these tiny muscles would probably be an issue in many of the digital deformities. This subject was addressed at a recent show of the podiatry chat show which goes out live on Facebook known as PodChatLive. In this show the hosts talked with Luke Kelly who has published widely in the field of plantar intrinsic foot muscle function and just how important they are. Luke reviewed the spring-like purpose of the human feet whenever walking along with the function of those muscles in that. Also, he talked about precisely why it's fictitious to believe a overpronated foot will be a “weaker” foot. Luke also describes why he is personally NOT a enthusiast of the ‘short foot exercise’ and just exactly why strengthening the intrinsic muscles should never result in the medial longitudinal arch ‘higher’ that is a commonly assumed myth.
Dr Luke Kelly PhD has more than fifteen years of clinical experience assisting people with pain resulting from bone and joint injury as well as long-term health problems. Luke has accomplished a PhD in biomechanics and is also actively interested in research that endeavors to enhance the understanding and treatments for frequent foot conditions, including plantar heel pain, the intrinsic muscles, foot tendon problems, osteoarthritis in the foot in addition to children’s sporting disorders. He currently is a Senior Research Fellow at the Centre for Sensorimotor Performance at the School of Human Movement & Nutrition Sciences at the University of Queensland in Australia. Luke’s latest scientific studies are studying how the brain and spine includes sensory feedback to change the biomechanical function of the foot when running and walking.
