13. Avaliação da percepção de dor aguda em pacientes com transtorno de pânico
Inducing pain and evaluating pain sensations in ethically viable ways have always been a challenging task for those conducting experimental research in Psychology and behavioral areas. This study has evaluated the nociceptive thresholds and the subjective experience of pain in 29 patients diagnosed with Panic Disorder and 29 healthy controls. The participant

14. Avaliação da sensibilidade cutânea em pés de pacientes diabéticos através do Pressure Specified Sensory Device TM / Evaluation of cutaneous sensibility threshold on the feet of diabetic patients with the Pressure Specified Sensory Device(TM)
Neuropathy is a severe progressive loss of protective sensation on the feet, making the patient more vulnerable to mechanical trauma and consequently more suitable to the development of chronic wounds, major distortion of the foot bone architecture and eventually to limb amputation. Prophylaxis should be enforced to avoid foot ulceration and for that, evalua

15. Comparative study of foot sensibility, with and without ulcer, in diabetic patients, using the Pressure-Specified Sensory Device (PSSD) / Estudo comparativo da sensibilidade do pé com e sem úlcera em pacientes diabéticos utilizando o Dispositivo Específico de Sensibilidade de Pressão - PSSD (Pressure-Specified Sensory Device)
O diabetes mellitus continua sendo uma doença de incidência crescente em todo o mundo, tomando proporções epidêmicas em nossos dias. Tal fato é acompanhado pelo aumento da prevalência de complicações relacionadas à doença, das quais as relativas aos pés apresentam os maiores índices de morbimortalidade. A perda da sensibilidade protetora é um f

16. Análise comparativa das alterações da sensibilidade cutânea após abdominoplastias / Comparative analysis of the alterations of cutaneous sensibility after abdominoplasties
A abdominoplastia é uma das cirurgias plásticas mais realizadas. A associação entre a lipoaspiração e o descolamento reduzido trouxe uma nova perspectiva em relação à maior preservação da inervação cutânea sensitiva. Novos métodos de avaliação de sensibilidade têm permitido melhor quantificação e uma análise mais completa da evolução p

17. Efeitos da estimulação elétrica do córtex motor na modulação da dor: análise comportamental e eletrofisiológica em ratos / Effects of electrical stimulation of motor cortex on pain modulation: behavior and electrophysiological study in rats.
Background. The motor function has been associated to sensory and pain attenuation, before during and shortly after the muscle activity. How ever the anatomical and functional basis of this phenomenon is not yet defined. The present study was designed to set an animal model and investigate the effect of subthreshold electrical stimulation of motor cortex (MC

18. The extent of small fibre sensory neuropathy in diabetics with plantar foot ulceration.
Thresholds for cutaneous warming and cooling stimuli were measured in 20 diabetics with neuropathic foot ulcers. All patients had a profound disturbance of sensory perception in the ulcerated foot with complete loss of perception of warming; thresholds for vibration and cooling were highly abnormal in all but two patients. Measurements of thermal threshold w

19. Sensory and pain threshold characteristics to laser stimuli.
The clinical applications of thermal sensory and pain thresholds have been very limited due to large intra-individual variations. In the present paper CO2 and argon lasers were used as thermal stimulators, and the different factors (stimulus parameters and skin conditions) affecting the thresholds are described. The intra-individual variations obtained in se

20. An improved automated method for the measurement of thermal thresholds. 2. Patients with peripheral neuropathy.
Thermal thresholds were determined by a new technique, at wrists and ankles in 143 patients with peripheral neuropathies of diverse aetiologies. Ninety-nine percent of patients (141/143) had abnormalities of one or both thresholds. In only two patients with mild/early Friedreich's ataxia were thermal thresholds normal. Electromyography was performed and fast

21. Proprioceptive, visual and vestibular thresholds for the perception of sway during standing in humans.
1. Thresholds for the perception of postural sway induced by gentle perturbations were determined for five normal standing subjects. In this context we understand 'perception' to mean 'able to give a subjective report'. The thresholds for the perception of movements that were equivalent to sway in velocity and amplitude were determined when the available sen

22. Depth sense aesthesiometry: an advance in the clinical assessment of sensation in the hands.
Fingertip depth sense threshold has been examined in fifty normal subjects using the simple pocket aesthesiometer invented by Renfrew. Index fingers possessed the lowest thresholds and little fingers the highest, whilst there were no significant differences between the same fingers of either hand. Sex and age (at least up to 70 years) had no significant infl

23. Sensory involvement in motor neuron disease: further evidence from automated thermal threshold determination.
Thermal thresholds were determined in 40 patients with motor neuron disease and in 40 age- and sex-matched healthy subjects. The thermal thresholds were estimated on the skin of wrist and ankle using an automated microprocessor controlled system and the "two alternative forced-choice method" of psycholphysical analysis. Abnormalities of thermal thresholds (g

24. Changes of cutaneous sensory thresholds induced by non-painful transcutaneous electrical nerve stimulation in normal subjects and in subjects with chronic pain.
Transcutaneous electrical nerve stimulation (TENS) of the nervi cutaneus surae medialis was applied to 59 healthy subjects and 30 patients suffering from chronic myofascial pain in one lower limb, with an intensity of current that induced a well tolerated tingling sensation. Each period of stimulation lasted 24 minutes. The thresholds of the tactile, tinglin
