Questionnaire for quadriplegia

Hello All,

I am searching for a questionnaire for my dissertation. My dissertation topic is "VENTILATORY MUSCLE TRAINING IN QUADRIPLEGIC PTS". I have taken outcome measure as PFT but there is little difference in it although subjective improvement is there.

The patient feels better in speaking, coughing, execising etc. I want some questionnaire on that can any one help me out in this or how to get that questionnaire on intenet because on internet I get their names only not full questionnaire

RESPIRATORY SYMPTOM AND HISTORY QUESTIONNIARE is one of them. I look forward to any replies

Have you tried looking in:
Measuring health: a guide to rating scales and questionnaires / by Ian McDowell
Imprint New York : Oxford University Press, 2006/

This describes all validated tests etc and where to get them.
