I am a starting Massage Therapist. Has anyone ever used a back brace or weight belt to help wiht mechanics?

I know it is easier to work a long time in this field if you use proper lunges, kneeling lunges and above all keeping the back straight. I haven't seen anyone using a back brace, but wondered if it would make sense to do so?I am a starting Massage Therapist. Has anyone ever used a back brace or weight belt to help wiht mechanics?
I have not used either support to help with mechanics, but it may be worth trying for the short term to help serve as a constant reminder to train yourself into proper mechanics. One concern to think about may be the support devices possibly developing into a ';crutch'; for you down the road if you used them long-term. If you depend on the support devices to hold your positioning, then it may be taking away from strenghtening the muscles necessary to keep you in those positions for long periods of time. Over let's say three years of using these devices, you may discover that it is difficult for you to work without these support devices, thereby creating a ';crutch'; in which you now need to rely on these devices to keep you working. Where on the other hand if you spent those same three years making conscious effort to train your muscles to hold these postures, they will strenghten as necessary and create healthy, habitual patterns that prolong your career. So, in other words, if you do not currently require a need for these devices, then it would not be advised use them for the long term, but maybe short-term use might be worth a try to get you going in the direction you want.
