This essay presents the experimental subject as a figure of modernity. It addresses notions of control, sensory thresholds, automatism, and human agency through a study of experimental psychology and psychological apparatus from the late 19th century to the First World War, juxtaposing this with notions of experimentation in early 20th-century avant-garde movements. The human subject of experimental psychology, defined by its inexpression as it awaits the stimuli of testing and measurement, is treated as a prototype for the present-day user of technological interfaces.

Rectal Distention

The rate and pattern of rectal distension affect rectal distensibility, perception, and anal relaxation in health. Because rectal urgency is a prominent symptom in fecal incontinence (FI), we assessed rectal distensibility, contractions, perception, and anal pressures during rectal distention in 21 healthy, asymptomatic women (age 61 ± 2 yr, mean ± SE) and 51 women with FI (60 ± 2 yr). Rectal staircases (0–32 mmHg, 4-mm steps) and ramp distensions [0–200 ml at 25, 50, and 100 ml/min with a phase of sustained distension (SD), lasting 1 min, between inflation and deflation]. The rectum was stiffer during rapid than slow ramp distention. This effect was more prominent at a lower volume (50 ml) and was also more pronounced in older subjects and in FI. A rectal contractile response was observed not only during inflation but also during SD and during deflation. During inflation, this contractile response was rate dependent in controls but not in FI. During staircase but not ramp distentions, the threshold for the desire to defecate was lower in FI. During ramp distentions, the duration of perception was significantly longer in FI. The rate of distention did not affect rectal perception (i.e., sensory thresholds or duration of perception) during ramp distentions. Baseline anal pressures and the magnitude of anal relaxation during rectal distention were also reduced in FI. In addition to reduced rectal capacity and compliance, women with FI had an exaggerated rate-dependent reduction in rectal distensibility, lower sensory thresholds, and more prolonged perception, indicative of rectoanal dysfunctions.

Level Of Agreement

Objectives The aim of this study was to compare the Electronic von Frey Anaesthesiometer (EVF) and the Small Animal ALGOmeter (SMALGO), used to measure sensory thresholds in 13 healthy cats at both the stifle and the lumbosacral joint, in terms of inter-rater and inter-device reliability. Methods Two independent observers carried out the sets of measurements in a randomised order, with a 45 min interval between them, in each cat. The inter-rater and inter-device reliability were evaluated by calculating the inter-rater correlation coefficient (ICC) for each pair of measurements. The Bland–Altman method was used as an additional tool to assess the level of agreement between the two algometers. Results The mean ± SD sensory thresholds measured with the EVF were 311 ± 116 g and 378 ± 178 g for the stifle and for the lumbosacral junction, respectively, whereas those measured with the SMALGO were 391 ±172 g and 476 ± 172 g. The inter-rater reliability was fair (ICC >0.4) for each pair of measurements except those taken at the level of the stifle with the SMALGO, for which the level of agreement between observers A and B was poor (ICC = 0.01). The inter-device reliability was good (ICC = 0.73; P = 0.001). The repetition of the measurements affected reliability, as the thresholds obtained after the 45 min break were consistently lower than those measured during the first part of the trial ( P = 0.02). Conclusions and relevance The EVF and the SMALGO may be used interchangeably in cats, especially when the area to be tested is the lumbosacral joint. However, when the thresholds are measured at the stifle, the inter-observer reliability is better with the EVF than with the SMALGO. The reliability decreases when the measurements are repeated within a short time interval, suggesting a limited clinical applicability of quantitative sensory testing with both algometers in cats.

Manual Stimulation

The effect of acupuncture on sensory thresholds was studied in 6 healthy subjects. The modes of acupuncture studied were: 1. manual stimulation, 2. electrical stimulation at 2 Hz, 3. electrical stimulation at 80 Hz. Superfiscial-acupuncture was used as placebo. Insertions of needles or application of electrodes were bilateral, at St 7 (intrasegmental) or Li 4 (extrasegmental). The study showed that manual or electro-acupuncture were effective when used intrasegmentally, raising pain threshold values 1.1 to 1.4 times that prior to stimulation. The pain threshold elevation obtained was not significantly related to plasma levels of beta-endorphin, ACTH or prolactin. Other sensory threholds, thermal, vibrotactile and electrotactile were unaffected by such conditioned sitmulation. Superfiscial-acupuncture had no significant effect on the sensory thresholds tested.
