Please note the ANZCTR will be unattended from Friday 20 December 2019 for the holidays. The Registry will re-open on Tuesday 07 January 2020. Submissions and updates will not be processed during that time.

Please be advised that as the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

Study type
Description of intervention(s) / exposure
Intervention Group: Modified abdominal hemodynamics maneuver applied over the whole abdominal visceral mass performed in three phases. In the first phase, the therapist places the ulnar border of both hands on hypogastric region asking the patient breathe widely so that in the inspiratory phase the therapist pulls the visceral mass towards its head. In the second and third phases, the therapist contacts with both hands respectively in the right and left patient iliac fossa and follows the procedure described above, so that in the inspiratory phase the therapist pulls the visceral mass to the left shoulder of the patient in the second phase and to the right shoulder in the third phase.
The intervention will be performed by a qualified physiotherapist with over 6 years of experience in the field of manual therapy. The intervention will be conducted in one session, performing 10 repetitions in each of the phases.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
An external consultant (holder of the allocation schedule) prevented access to the sequence for those participating in the study.
The allocation involved contacting the holder of the allocation schedule who was at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomization using a randomised number table designed by an Internet website (
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Brief summary
The aim of this study is to assess the effect of a visceral manual therapy intervention in pressure pain threshold , back range of motion and lower limbs extensibility sensitivity and posture in subjects with functional chronic constipation (CC).

The main hypothesis of the study is that a visceral manual therapy intervention called modified abdominal hemodynamics maneuver in patients with functional chronic constipation will cause a change in the sensitivity of trigger points of a range of tissues in diferent sparts of the body, a change in the mobility of the spine and pelvis in flexion, and at last a postural change
