I found the nordic poles useful when we lived in Colorado when we hiked the Rockies.  Easy on the knees and stability when we scrambled upwards over rocky areas.  I cannot remember which model poles we had but they were aluminium types from Leki that has a ” shock absorber” at the tip. Putting the medic cap on, I think the poles worked by allowing us to shift our center of gravity forward safely for stability and allow our upper limbs to supplement our legs and butt muscles with the gentle climbing. The patients with knee problems find it more useful walking down an incline.
