Will Kranking aggravate a shoulder rotator cuff injury?
A. The repetitive action involved in Kranking actually seems to be therapeutic for shoulder injuries of this nature, possibly because of the increased localized blood flow. We have found this to be true in the hand-cycling community, where crank-arm length and axis are similar to those of the Krankcycle. Rotator cuff injuries are fairly common and may be caused by falling, lifting and/or repetitive arm activities performed overhead (e.g., freestyle swimming). Poor posture, especially protracted (rounded) shoulders can also contribute to rotator cuff injury. This may be one of the greatest, unexpected benefits of Kranking. TBD.
