Trust your neuro for goodness sakes. He/she and team will know which muscles to test. It was weird in my case,... They kept sticking my right side while I had complained of my left side issues. You see? They must know what they're doing. The vast majority do. And are competent and highly trained. Please don't get mired in other non medical people's opinions. It serves no useful purpose and you'll get wrong information. Enjoy your weekend!
