Chronically tight, painful left side muscles: lat, psoas, erector spinae, QL and tfl/it band with constant trigger point in QL. The right side is under-firing or prone to "amnesia" in the glute and quads with LCL pain at the knee under load between 100-150 degrees.

Left foot has a tender spot at the ball in the center below the second and third toes. Foot doctor says there is nothing wrong, but I can tell it has changed the way my body moves and shifts weight, and I think it could be contributing to the back pain on that same side. Once a year I experience a seemingly random day without pain, but cannot decode the conditions which cause it. I've tried magnesium supplements. Sometimes they offer relief, other times it makes it all worse. Massage is the same way. I am trying to focus on strengthening legs, glutes and core muscles. I think it could largely ..read more

Calculating Foot Pressure force of individuals

Hello, I have a mechanism that has a foot pedal on its bottom. The user will press this pedal with their foot while standing. My target audience is women in their 50s-60s and not working out. So they have to press this pedal neither exerting too much force nor using their body weight. I searched some ergonomics literature and only found things like pedal pressure force of drivers or cyclists. I couldn't find anything regarding my problem's conditions. How can I calculate the force they can produce under these conditions? How can I advance in this situation? submitted by /u/Mrhappyrulez [visi ..read more

Ergonomic tests for measuring muscle strains generated from writing
Reddit - Biomechanics
by /u/Comprehensive-Ad1072
1w ago
I want to evaluate the relationship between pen dimensions and the strain generated on wrist and arm muscles while writing. Which ergonomic tests should I conduct? I am thinking of using EMG muscle sensors for measuring muscle stress. But placing it on the lower side of the arm (where majority strain occurs) would not be comfortable for the test subject. This would ultimately change his natural writing posture and will not provide accurate data points. What could I solve this challenge? submitted by /u/Comprehensive-Ad1072 [visit reddit] [comments ..read more

Looking for hand specialists to discuss hand movement in piano technique

I'm a professional pianist with a masters in advanced performance writing a book on a modern approach to piano technique and feel I have gone as far as I can in my research into the biomechanics of the hand without being able to ask questions to a specialist, specifically regarding the detailed function, sensation and interaction of the ulnar, radial and median nerves and the exact movements possible using the intrinsic hand muscles which are almost completely ignored by modern piano pedagogy. For example, the act of healthily playing a note with a finger utilises the flexor system but with t ..read more

Symptom: Chronic pelvic floor tension - Cause: Undetermined...
Reddit - Biomechanics
by /u/Even-Novel6277

Hi, I recently got custom orthotics and my biomechanics have improved considerable. I had one drooping shoulder; twisted hips and left foot over pronation. I have had chronic pelvic floor tension for years and think it related to the need for orthotics. It has improved slightly but still very much present. I now pass multiple ROM tests under the PRI(Postural restoration institute) methodology. Including but not limited too; Straight leg test, hip flexion test, HIP IR and ER almost perfect but not quite. Shoulder IR/ER perfect now. Any thoughts on what I can do to improve more rapidly? I'm sti ..read more
