Many thanks that is really useful.

One more isssue with this lady is the surgery seems to have affected r > L arms, both limited in rom active and passive,

pt says mvt stopped by stiffness - passive hard end range feel and stiff

no p/n, no numbness, no pain, has sensation to light touch, performed some tests eg speed, empty can, neers all -ve,

given active assisted and gravity assisted and pendulum x's but bit puzzled with arms
but decided to work on trunk first as without that she isn't going far?
