Abstract

This report documents the quantitative and qualitative response of a restrained, sensory-deprived subject (Specimen “Fae DCay”) to high-velocity plantar tickling. Within 10 min of stimulus onset, the subject’s affective state transitioned from reflexive laughter to muffled sobbing, validating the hypothesis that absolute immobilization combined with total sensory blackout amplifies low-threshold mechanoreceptor input to the point of psychological overload.

Methodology

Apparatus

Fettishlabs Tickle Table Mk IV – carbon-steel frame, 2.1 m length, 0.8 m width, integrated slot-strap matrix. The Immobilizer (Fettishtools.com) – full body leather sheath, 14-point lockdown. V2 Rigid Stocks – hardened 4140-steel ankle recesses, 0° dorsiflexion, 0 mm lateral play. Ratcheting T-B*r – surgical-grade stainless, micro-adjustable toe retraction to 110° hyper-extension. Sensory Block Kit – blackout blindfold (OPACITY ≥ 99.8%), 30 mm memory-foam gag wrap, 34 dB reduction earplugs, industrial earmuffs (OSHA 29 dB NRR).

Subject Profile

Designation: Fae DCay S*x: F Height: 5ft 4 in Shoe size: 8 (high plantar curvature, ticklish index 9.2/10 via pre-test). Consent: Full; safe-signal = clicking device placed in hand and bound within Immobilizer.

Protocol

Subject stripped, c*tton sock removal.
Immobilizer harness cinched (torso compression 4.5 cm).
Ankles locked in V2 stocks; torque verified at 40 Nm.
Toes individually cord bound (8mm 550 paracord - tensile strength 75lb) to T-B*r; ratchet tensioned until plantar fascia fully taut.
Blindfold, gag, earplugs, earmuffs applied.
Leather straps threaded through table slots; buckles pull-tested (max slack 1 mm).
Baseline vitals: HR 78 bpm, cortisol 6.1 μg/dL.
Stimulus onset: investigator applies continuous tickle-stimulation across bare plantar surface at 4.2 Hz, f= 0.9 N.

Observations

Subject vocalizes staccato laughter into gag; metatarsal flexion attempts produce zero movement (verified by high-speed camera 1000 fps).
Laughter acquires tremulous edge; micro-sweat beads form on plantar arch.
First tear observed at lateral canthus (blindfold gap monitored).
Vocalization shifts to muffled sobbing; laughter near absent.
Heart rate peaks 142 bpm; galvanic skin response + 470%.
Subject triggers safe-signal; stimulus terminated.

Discussion

Complete elimination of auditory, visual, and proprioceptive reference frames collapses anticipatory gating, triggering the central nervous system to allocate extraordinary bandwidth to the remaining somatosensory channel (plantar glabrous skin). The transition from sociolaughter to laughter mixed with sobs corroborates prior rodent data on unpredictability-induced panic amplification.

Conclusion

The experimental configuration produced an escape-proof environment wherein targeted tickling of the immobilized barefeet precipitated acute emotional fracture in < 11 min. Replication advised with n ≥ 10 to establish population-level thresholds.

Compliance

All restraint hardware tested to 3 × safety factor. After-care included 15 min ungagging, hydration, and bilateral foot massage to restore circulation. No persistent edema or tendon strain detected.
