First of all... has she been a client to the clinic before, and are all the tables the same? ย I am assuming that she has been there before since you have the heads up on her size. ย For your own sake, find out what weight the table can handle and just estimate. ย If she has been there before, and everything went fine, I wouldn't worry about it unless she is on the fringe of the table weight. ย I would drop my table a few notches that way you are comfortable and are not straining yourself through body mechanics. ย Also, watch when she gets on the table, if it creaks and bows (common sense) is that she is too heavy and should not be worked on, and your added pressure can collapse the table, especially if it is a portable table. ย Because the last thing you need is to get hurt before you are even out there, and you really don't want your client to get hurt.I definitely know what you mean, when I was in school, I convinced my shiatsu teacher to let us work on the tables, because I have had 2 knee surgeries and can't kneel down so working on the floor is extremely difficult. ย Now I am not a small woman, I am very athletic, large framed and dense. ย So I am not a lightweight, well my partner for the day was a woman who makes me look small... ok, so when we were working we had to sit on the table to get the connection and do the hara assessment... well oh boy did that table creak and shift when she sat down. ย I know we were maxing out the weight and since it was a portable table, it isn't one flat slab of wood... I was so afraid that we were going to end up on the floor!!! ย By the way this was a wooden aurora oakworks table. ย So just take precautions and use common sense. ย I know it will be hard to turn away a client, but safety should be your first concern. ย But if she has been there before, she feels safe and has come back, and you will be ok.
