F- CLINICAL ASPECTS OF SPINAL CORD INJURIES
435
The technique adopted of recording intraluminal and colonic activity pressure was
that of Rowlands
et al.
(1953) an<^ Atkinson
el al.
(1957)5 using miniature balloons
connected by fine polyethylene tubing to a metal capsule optic manometer of high sensi
tivity. Only in one patient (case 22) was a wireless telemetering capsule (Connell & Row
lands, 1960) used. The tubes and recording balloons, still attached to the manometer,
were passed into the colon through the sigmoidoscope, which was then withdrawn. The
recording tips were placed routinely at 15, 20 and 25 cm from the anus—i.e. they lay in
the rectum and in the sigmoid at the recto-sigmoid angle respectively (Fig. 184). Respira
tory and body movement were recorded by a stethograph around the upper abdomen and
STETHOGRAPH.
