i haven't read much literature on the importance of stretching the lower limbs... i have found some good stuff on the importance of stretching the upper extremity, particularly the internal rotators of the shoulder...
but it IS common knowledge that we must maintain flexibility and certain specific ranges of motion if we want to have our patients be able to ambulate with a normal gait pattern...
so consider this: i stretch and mobilize an ankle that has a 5 degree plantarflexion contracture... i gain 10 degrees-- so it now has passive range of motion of 5 degrees dorsiflexion... now what?? just forget about it?? we ALL know that it'll end up losing what we've gained if we just let the patient go about their day... so obviously we need to use splinting, casting, etc, to our advantage... placing this foot into an ankle-foot-orthotic would then be ideal...
now, i don't really think i need a research article to tell me that maintaining a 0-5 degree dorsiflexion range is better than a 5 degree plantarflexion contracture....
sometimes people worry so much about the literature and evidence-based practices... what about simple logic??
