When Biomechanics Fail You: Different Variables to Consider

By Kento Kamiyama PT, DPT

Have you ever hit a wall with your movement? You followed all the biomechanical or form cues with no difference in how you feel.

You’re not alone in this process.

When I hit this wall, I immediately thought, “The biomechanical model is wrong”. With experience, I refined my understanding to the biomechanical model was not integrating with ME. The information that I was using wasn’t integrating with my internal model of how I feel my body and movement.

My internal model has decades of conscious and unconscious information on my autonomic system, skeletal system, and movement system. When information from the outside is not connecting with my internal model, it’s hard to make progress because it’s hard to relate.

This can happen for many reasons:
– Lack of references (new language)
– Lack of foundational information (too complex)
– The movement or language feels unsafe for the individual
– It ‘feels’ off (gut feeling, trauma response)
– Clash in information/belief
– Lack of trust with the author of the information

Nevertheless, I have learned that the biomechanical model is not necessarily ‘wrong’. I wasn’t connecting the information with how I felt. Because I forced the information on myself, I neglected how I was feeling. When I neglect how I feel, and logic takes the driver’s seat, the body and the mind conflicts.

By integrating and accepting my internal world, it provided a compass on how to integrate the information on the outside with myself.

There is more to say about this topic. For this blog, I’ll introduce a video of me trying to give you a different way to approach movement. Hope you enjoy.
