KLPGA professional golfer Kim Hye-yeon states that when golf shots are inconsistent on the course, the problem is often misaligned aiming rather than swing flaws. ^[1] A 2010 study using magnetoencephalography found that brain responses to self-generated touch were approximately five times weaker than responses to externally produced touch. ^[2] In 1998, researchers Sarah-Jane Blakemore, Daniel Wolpert, and Chris Frith published a study in Nature Neuroscience using functional MRI to show that the somatosensory cortex was more active during external touch than self-generated touch. ^[3] Nacho Roura, a neuroscientist and science communicator, explains that the cerebellum helps anticipate the sensory consequences of our own actions before they happen. ^[4] The brain predicts sensory consequences of movements, such as the timing and intensity of contact, allowing it to reduce its response to self-generated touch. ^[5] Kim Hye-yeon explains that the eyes, ears, and cerebellum work together to create the body's sense of direction, and if this sensing is off, it leads to incorrect alignment. ^[6] The article claims that recalibrating the body's internal sensing system can make aiming more comfortable and improve swing confidence. ^[7] The author describes the Fukuda Stepping Test as a method to check if the body's balance sensing is biased to one side. ^[8]
