Primary Outcomes

Description: Tcore will be continuously monitored throughout baseline and thermal challenge periods (with heated & non-heated vests) by a TX-2 Rectal probe and Iso-Thermex Multichannel Thermometer (Columbus Instruments, Columbus, OH). The probe will be placed 10 cm beyond the anal sphincter.

Measure: Change in Core Body Temperature (Tcore)

Time: Visits 2 & 3 (subjects with tetraplegia only): Continuously throughout baseline & Thermal Challenge (2 hrs) periods. The change in Tcore from baseline to the end of Thermal Challenge will be determined.

---

Description: The cognitive battery will be administered once at BL and once after Thermal Challenge in persons with tetraplegia only (Visits 2 & 3). Testing conditions will be identical, quiet, and distraction-free. Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV): Subjects will be asked to repeat 2-9 numbers forward, backward and in ascending order to assess attention, processing speed, and working memory. Each assessment requires 10 min.

Measure: Change in Cognitive Performance: WAIS-IV

Time: Visits 2 & 3 (subjects with tetraplegia only): At the end baseline (at 15 min) & end of Thermal Challenge (at 120 min) periods. The change in cognitive performance from baseline to the end of Thermal Challenge will be determined.

---

Description: Delayed Recall section of the Montreal Cognitive Assessment (MoCA): Subjects will be asked to repeat 5 simple words immediately and then recall them after a 5-minute delay to assess working memory. Each assessment requires 6 min.

Measure: Change in Cognitive Performance: Delayed Recall

Time: Visits 2 & 3 (subjects with tetraplegia only): At the end baseline (at 15 min) & end of Thermal Challenge (at 120 min) periods. The change in cognitive performance from baseline to the end of Thermal Challenge will be determined.

---

Description: Stroop Color and Word: Subjects will be asked to read words of colors, colors of fonts to assess attention and processing speed; color of fonts of words which describe conflicting colors to assess response inhibition (executive functioning). Subjects will practice each of the assessments for approximately 10 seconds prior to the actual test to ensure understanding of the instructions. Each assessment requires 4 min.

Measure: Change in Cognitive Performance: Stroop

Time: Visits 2 & 3 (subjects with tetraplegia only): At the end baseline (at 15 min) & end of Thermal Challenge (at 120 min) periods. The change in cognitive performance from baseline to the end of Thermal Challenge will be determined.

Secondary Outcomes

Description: Thermal Comfort will be measured every 10 minutes throughout BL and thermal challenge periods by the Zhang 6-point thermal comfort scale: +3 (very comfortable), +2 (comfortable), +1 (just comfortable), -1 (just uncomfortable), -2 (uncomfortable), and -3 (very uncomfortable). A greater frequency of +1, +2, and +3 scores are considered more desirable than -1, -2, and -3 scores during the Thermal Challenge. Each assessment requires only the time needed for the subject to respond (typically less than 10 seconds).

Measure: Change in Thermal Comfort (TC)

Time: Visits 1, 2, & 3 (all subjects): During baseline & every 10 minutes throughout Thermal Challenge (2 hrs). The change in TC from baseline to the end of Thermal Challenge will be determined.

---

Other Outcomes

Description: Skin thermocouples (TX-4 Skin Surface probes, Columbus Instruments, Columbus, OH) will be taped to 12 sites on the anterior trunk. Tsk data will be collected continuously throughout the baseline (BL) and Thermal Challenge periods. All areas under the vest will have skin temperatures less than or equal to 39 degrees C.

Measure: Change in Skin Temperature (Tsk) under the heated vest

Time: Visits 2 & 3 (all subjects): Continuously throughout baseline (15 min) & Thermal Challenge (2 hrs) periods. The change in Tsk from baseline to the end of Thermal Challenge will be determined.

---

Description: Thermal sensation will be measured on the Zhang 9-point Thermal Sensation scale: +4 (very hot), +3 (hot), +2 (warm), +1 (slightly warm), 0 (neutral), -1 (slightly cool), -2 (cool), -3 (cold), and -4 (very cold). TS should be no greater than "warm" this would include identification of "hot spots". Each assessment requires only the time needed for the subject to respond (typically less than 10 seconds).

Measure: Change in Thermal Sensation (TS)

Time: Visit 1 (able-bodied subjects only): During baseline & every 10 minutes throughout Thermal Challenge (2 hrs). The change in TS from baseline to the end of Thermal Challenge will be determined.
