Yes, but this may make it more difficult for the patient alone to apply the collar. The Assist Strap is attached with a button, so if you wish to remove it, it may be unbuttoned. Then the Strap may be reattached later if desired.
Can I use just the front of the collar with the Assist Strap?
No. You need to attach the back piece to get proper immobilisation and support.
How can I tell if the collar is on correctly?
The words "Front" and "Back" are embossed on the appropriate pieces. Also, "Up" arrows are molded into the front and back pieces.
