Dont know if this will help or not but i have wrist (discomfort lets say) . What i do differently now is to do with the ladder.Instead of just grabbing it and making it go where i want i move it more slowly,use the ladders own weight to move itself by angling it about,i take it off the roof more slowly,pulling it to me and trying a roll-off manouvre,its a fact i can give my wrists more abuse than most things by trying to wrag a ladder about.If i am climbing the ladder i make it all leg work instead of pulling myself up.I still try and get tops of jars when asked and i can have wrist ache for ages after doing this.I had one go at getting the top of her indoors nail varnish yesterday and it was like an electric shock going through one wrist so off i went to the shed and got the stilson wrench on them,total doddle.Thats it really,just that suggestion of not overloading the wrists with the ladder,Oh and using a stilson wrench to get the tops of nail varnish.
