"Repetitive type injuries and conditions (as opposed to incident /impact type) relating to joints and connective tissues of the arm can be brought on and aggravated by various factors:
• Too much too soon – probably the most common factor is increasing the workload too quickly; whether it is raising the number of paddling sessions, increasing mileage or speed, upping boat weight or even going from regular paddling in calm conditions to prolonged poor weather paddling - all should be done in gradual increments. Experienced paddlers can (and do) suffer from this as well as less experienced paddlers; workload itself is not the most significant factor – rate of change of workload is. And this relates to your recent sustainable workload, not what you did or could do 5 or ten years ago!
• Imperfect grip – poor technique relating to the grip and hand positioning/movement can cause strain. A light open grip with opening fingers on return phase of stroke will help. Sometimes a slight wrist rotation of the none control hand when feathering the paddles can be a factor.
• Too stiff, too large – paddling with a shaft that is very stiff or with paddle blades with too large a surface area will likely cause problems as the shock loads are passed up the arm – something tends to give eventually. Bear in mind that for the same construction a split shaft or cranks will likely be stiffer than a one piece shaft.
• Change of kit – this develops from the too much too soon idea. New kit probably doesn’t handle the same as your old kit so if you change to a new style of blade or boat etc then ease off the workload a little until things have had time to adjust.
• Shaft diameter – different size hands need different size paddle shafts. Too large, too small can cause problems, but it is usually too small that causes the more significant problems. These are more likely to be seen as problems in the hand and fingers rather than the wrist - numbness, pins & needles, circulation problems and finger tendonitis.
• Inappropriate feather – a very individual thing!
• Non-paddling activities– RSI type factors such as overuse of computer keyboard/mouse, power tools etc. Also alternative sports (or any activity with repetitive hand movements) may cause problems when linked with paddling.
• Latex cuffs – not entirely convinced by this one but there have been numerous examples of paddlers who think that too tight a latex wrist cuff have caused aggravation.
• And sometimes there just doesn’t seem to be an obvious reason – s**t happens I suppose.
