Many activities require the wheelchair owner to reach, bend and transfer in and out of the wheelchair. These movements will cause a change to the
normal balance, the center of gravity, and the weight distribution of the wheelchair. To determine and establish your particular safety limits, practice
bending, reaching and transferring activities in several combinations in the presence of a qualified health professional before attempting active use of
the wheelchair.
