Paraplegic Excersize advice

Hi all,

I hope I am positing this in the correct place. I'm an incomplete para. I can walk with 2 elbow crutches but only for short distance as I am a combination of very unfit & don't feel comfortable in public on the crutches. I had a motorbike accident that resulted in my L2 vertebrae bursting.

I would like to know some exercises I can do to improve my balance. I cannot stand unaided unless I am bent at the knees (which I don't fully understand)

I don't have any meat on my bum and would like to get some muscle activity there but all the exercises I have seen would require me to stand (squats, lunges etc). I walk on my treadmill have an exercise bike and a multi gym but these don't seem to work the "little muscles". The other area I think needs improving is my hip muscles. When I sit on the edge of my bed and try and lift my leg, bent at the knee, the bottom part of my leg pulls inwards. I have looked up hip muscle exercises and found an exercise where I lay on my side and try and lift my away from my other leg. I can't manage this and would appreciate some exercises that work the hip muscles indirectly.

I hope that made sense, it's difficult trying to write and describe the above! I would really appreciate your thoughts and thank you for taking the time to read this.
