In regards to your clinical question, QL/low back, hip external rotator muscle and sciatica issues occurring together is something I see in the clinic on a fairly regular basis. In my mind, much of this probably has to do with the origin of the sciatic nerve (branches in the lumbar spine) and its path through the posterior hip region. I often find that a combination of spinal facet joint mobilizations, soft tissue work through the lumbar spine (including the QL) and the posterior hip region and exercises (hip and lumbar mobility and nerve mobilizations) help with these symptoms. You might find the exercises in the piriformis/deep gluteal pain syndrome program here in the app to be helpful. Here is a link to that program.

Hi Shaf, It's great to meet you and learn about your clinical background! The combination of massage therapy and personal training is such a good one. I would imagine you are quite similar to me in that I also combine manual therapy and exercise. Thank you for joining my app and community. Also, thank you so much for buying my book and for sharing my work with others. I really appreciate it!

Regarding your questions, if you look at the top of the home page just below the featured section, you will see a search bar on the left and a 'filters' area on the right. If you click on filters, there is an area where you can search by muscle group. I need to build this out more, but this may help with some of your searches. I have attached a screenshot where you can see the filter area across from the search bar.

Hi Anagha, It's great to learn more about you! Your work sounds very interesting. I had considered being an Air Force physical therapist when I first graduated from my DPT program, so it's cool to learn that you are doing similar work. 

Thank you very much for following my content for so long and for your kind comments! If you make it to California next year, please let me know.
