The first thing to remember when beginning to use a zimmer frame is that the frame is there to aid you, to assist you and should require absolute minimal effort from you.
A zimmer, or walking frame is purposely made to be lightweight so that you can move it forward or sideways without exertion.
If the frame is adjustable you should make sure that it is at the most suitable height for you and that you place your hands on the grip area of the frame, this area on a standard zimmer frame will usually be on the left and right side sections of the frame, having your hands placed in the correct area will help to prevent slip and provide you with a comfortable area to grip onto.
When using a zimmer frame outdoors it is important to keep to even ground as much as possible, sometimes paving stones can dip, although its impossible most times to know if one will, but also areas of streets can at times be uneven so when walking with the use of a zimmer frame and with the option to use a more even looking surface its best to stick to this.
With a standard zimmer frame (without wheels) where you pick up the zimmer frame and move it slightly forward its always safest not to attempt to move the frame too far forward that you may feel less stability, moving the frame forward just enough so that you can take your steps safely and without added effort is the best approach to use.
The main use of the zimmer frame is to provide you with balance and stability as you move around your home and as you walk outdoors.
