I hesitate to use the word "posture" due to the various models it conjures in people's minds (slouching, pictures of the spine etc.) Put these images aside for a moment.
Posture = Position of the body.
All the body, at any time.
Good posture = good positioning - the body works well.
Poor posture = bad positioning.
(Bad positioning could be structural or due to inappropriate usage)
Bad positioning is bad for moving parts. Inappropriate tensions, misalignments, friction, stress.
Bad things in the body - detected by sensors, information transmitted by nerves, brain says PAIN!
The body adapts over time. Pain progresses if bad positioning is not corrected.
(One adaptation I propose - physical restrictions in connective tissues form in a response to inflammation, which can be triggered by a multitude of things. Over time these restrict range of movement, apply tension, generate pain. The body is very adaptable. It can take a lot of stress and abuse. The mind can ignore a lot of pain signals. An individual's awareness levels and tolerance affects when issues are noted/treatment is sought i.e. become clinically significant.
I'm about 60% confident that this gait alteration may be involved in the idiopathic foot pain
This is a good example of what I mean by "poor posture" causing pain. Gait alteration = changing how you move = altering posture/position. If these alterations have resulted in pain, I'd classify it as postural pain i.e. pain due to poor positioning.
Consciously changing your gait involves the activation of different muscle fibres to what you have been using. Either this is "corrective" (improving positioning with activation of the 'right' muscle areas) or it's detrimental to positioning with increased use of the 'wrong' areas of muscle (causing stress on muscles and a progression of issues. Myalgia, spasms, fatigue, trigger points → tensions in tissue, pulling on periosteum "joint pain" which stimulates bone remodelling/osteophyte formation ... )
If you are at 60% in thinking a gait change and your foot pain are connected, then I hope you'll give real consideration to my model for otherwise unexplained pain. (I've taken a very sudden active dislike to the word idiopathic, it's not idiopathic pain - anymore.)
My model fits with all the information I've seen over the years - quote and link to any studies you find relevant and I'll explain how. I joined LW with a "please rip to shreds" about my Base-Line theory of health and movement so please do! I am p>99.999 confident that what I propose is right. I'd like that rigorously tested. Break me, crush me. Release me from the frustration of knowing (with every fibre in my body) that I'm right ; )
I'm also looking to better understand my PF pain.
Keep studying the anatomy.
Focus on where the pain is coming from. Deep breathing, explore with your mind.
Bear in mind, dissection photos of pre-prepared specimens are usually designed to demonstrate components rather than showing the natural state of a joint. Schematic diagrams are just that, ligaments look like strings or ribbons crossing joint spaces at specific points, they don't show that most connective tissues aren't discrete parts, they blend from one named structure into another. Ligaments being thickened bands within a web of connective tissues around a joint, closely associated with fascia, joint capsule and periosteum, which then blends to tendons and aponeuroses to connective tissues containing myocytes ("muscles").
Have a look at dissection videos of the knee joint. (preferably fresh rather than pickled tissues). After removal of the skin it's obvious how much of everything is encased in connective tissues - a bright white 'bandage' of fibrous tissue (mostly collagen). The ligaments of the knee are thickenings in this web of connective tissue. A bit of tension somewhere pulls on surrounding areas.
The experience of handling a (skinned) knee brings another level of understanding. Seeing the layers. Feeling where bits attach tightly to bone. Feeling the bits that glide as the knee flexes and extends. The change in tension of various thickenings in the tissues around the bones. The trochlear groove for the patella. There is much to experience. Goat or sheep knees (known as the stifle) are a reasonable approximation if you do want to really get to know the knee.
The joints of the leg - hip, knee, ankle, foot offer a lot of potential for movement. The knee joint is mostly extension/flexion, it has very little medial/lateral movement - there is almost no slack. Any issues above or below the knee (rotations, tensions etc. from the hip/ankle/foot which put the leg in a less than ideal position) will show first in the knee. (The hip and ankle/foot have much more slack so can cope for longer with mal-positioning/misusage but it will appear with poor positioning).
This has good rather long and I'm out of time, but if you are interested - I could run through a diagnostic process for knee pain.
