Physical Therapist Recommended that I use Walking Poles & Rule of 3

In 1980 I was in a traffic accident, shattering my right leg from the knee down. After many operations and procedures, an orthopaedic traumatologist felt the best option was to perform an ankle fusion on my right ankle.

I recently had an evaluation done by a physical therapist who recommended that I use Walking Poles during my morning walk to
alleviate back and hip discomfort and thereby make walking more enjoyable. Is it possible to ‘test walk’ your poles?  I have bought items in the past only to find that they did not work with my type of injury.

Please let me know if this is a possibility.
Thanks.

NOTE FROM AFTER PURCHASING KEENFIT POLES (Did not ‘test walk’ them previous to purchasing):

I have been using them during my morning walk and they have made a difference.

Before using the Walking Poles, my knees, hips and lower back caused me a great deal of discomfort after my daily walk. Using the Walking Poles, the discomfort has been greatly reduced.

As recommended I have ‘test walked’ the Walking Poles 3 times; I think like any other form of exercise one has to get into the ‘Pole Walk’ rhythm. I now looking forward to my morning walks. Many thanks.
