Abdominal Breathing Exercises

  1. Strength Training– What is the recommended number of iterations to do during one session?  No specific amount – gauge on the patients fatigue rate.  Minimum of 5-10.
  2. Strength training– Is there a recommended method for establishing what the target pressure for squeeze should be?  Yes, the target pressures for the squeeze training is based on the squeeze trials for the manometry.
  3. Sensation Training– What is the recommended number of iterations to do during one session?  No specific amount – gauge on the patients perceptions. Minimum of 5-6
  4. Sensation training– how large of volume increases decreases are recommended? Small amounts 10 ml  Is there a sample list of volumes used to see the type of adjustments a therapist would make? We could do this – this is very subtle
  5. Sensation training– What sort of squeeze does the patient do and at what point are they squeezing? They squeeze when the fell the balloon inflations – same type of squeeze as practiced in the strength training.
  6. Sensation training– Since you do not want the patient to see the screen or when you are inflating the balloon how do you coach them to tell you they feel it as you go through multiple iterations of the test? Same type of squeeze as the strength training.
  7. Urge Resistance– Can we clarify the portion of instructions referencing 15cc of air? Is the system warning us not to deflate the balloon below 10cc as we move around the sensation threshold? Wouldn’t a situation like this be extremely rare if normal sensation volumes are between 30-50cc?   No system warning, just a recommendation to deflate the balloon to help decrease urge sensation.  We really are trying to work with the “strong urge” sensation here and not the initial sensation.
  8. Urge Resistance– Is the step sequence as follows: Fill to normal urge- record. Fill to Strong Urge- Record. Remove 30cc air- Record. Pause and have patient to breathing exercises. Start test and fill balloon to strong urge. Remove 30 cc air- Record. Pause and do breathing exercises.  Yes, but we also recommend removing 15 cc (see #7).
  9. Urge Resistance– Is the goal to increase the threshold at which strong Urge is experienced? YES
  10. Urge Resistance– Why are the breathing exercises done after the air is removed rather than during the strong urge experience? To help practice the behavioral aspects of trying to relax – one can do these with both.
