Because I have undergone surgery for fusion of my ankle. I may not put weight on my left leg for six weeks I have three to go. Neither crutches nor a Zimmer work for me. I expected to be housebound and get round on my hands and knees. Searching the internet I found a variety of wheeled devices which doubtless perform much the same function as the Peg leg. But they could not get me out outside. The peg leg would do that - I could cross the frame at the bottom of the door and step down to the front drive. I bought it Delivery arrangements were poor I found assembling the crutch easy. Demonstrably a great deal of skill went into the design. Classic British skills then? Actually not - Good Old USA. Well done. In just short of a week I am confidently walking around the house and using the stairs up and down. Yes it has got me in and out of the house - and I have been able to transit car parks and crowded restaurants - it's quite good for getting good tables too! There is a down side. My house is on sloping land and I do not yet have the confidence to walk out and up the road. Meantime here are some thoughts in case they help: From assembling the iwalk it is clear that considerable engineering skills have been exploited to bring it to where it is today. Even so there are two particular modifications I would encourage: Assembly There are attached to the central leg two tubular outriggers. They are secured at their base to the frame by a plastic headed bolt and screw. No problem here. The Central leg comprises two movable tubes which are adjustable for size. They are locked by two spring loaded ball bearings. The springs were too strong for me to depress. I had to resort to an adjustable wrench. Not everybody with my difficulties keeps such a tool close by! I recommend replacement of the ball bearings by a plastic headed bolt and screw similar to that described above. Adjustment The iwalk needs to be attached as tightly as possible. For this there are two adjusting buckles with tabs on each of the three straps. The idea is that once the tab on the black buckle is set it needs no further attention and can be buried in the protective cover. That leaves the tab on the grey buckle to be adjusted for daily use. Unfortunately it does not work like that. Because the tab on the grey buckle is too short it is necessary to set the tab on the black buckle every time the iwalk is fitted. Perhaps this problem can be resolved by extending the tab on the grey buckle.
