The quantitative sensory testing is an efficient objective method for assessment of nerve injury

Abstract

BackgroundThis study evaluated Somatosensory evoked potentials (SEP), Quantitative sensory testing (QST), and thermography as diagnostic methods for nerve injury.MethodsFrom 2006 through 2011, 17 patients (mean age: 50.1 years) from OOOO Hospital who sought care for altered sensation after dental implant treatment were identified. The mean time of objective assessment was 15.2 months after onset.ResultsSEP of Inferior alveolar nerve(IAN) was 15.87 ± 0.87 ms on the normal side and 16.18 ± 0.73 ms on the abnormal side. There was delayed N20 latency on the abnormal side, but the difference was not statistically significant. In QST, the abnormal side showed significantly higher scores of the current perception threshold at 2 KHz, 250 Hz, and 5 Hz. The absolute temperature difference was 0.55°C without statistically significance.ConclusionThese results indicate that QST is valuable as an objective method for assessment of nerve injury.

Spontaneous healing of lateral femoral cutaneous nerve injury and improved quality of life after total hip arthroplasty via a direct anterior approach

“…It enables to identify the clinical symptom as neuropathic symptom. 2,21 However, it is a possibility that uncomfortable symptom for the patient is underestimated in some cases. 2,21 Consequently, the incidence of LFCN injury may be underreported.…”

Injured Anterior Superior Alveolar Nerve Endoscopically Resected within Maxillary Sinus

“…Documentation of infraorbital, nerve-innervated skin involvement with nerve injury can be done with quantitative sensory testing, and has also been well described 9232425. Normal neurosensory testing of the upper lip, with a positive response to local anesthetic block of the ASAN, documents injury to the ASAN branch of the infraorbital nerve, and suggests the location of the nerve injury in the region found in the patient in the case reported here.…”

The diagnosis and management of nerve injury during endodontic treatment

“…The methods used for neurosensory function evaluation differ significantly, extending between basic patient questioning and complex examinations (Kim et al, 2015). However, the fundamental marker of a sensory malfunction is the patient's own subjective complaints (Yatsuhashi et al, 2003;Pogrel, 2007;Juodzbalys et al, 2011;Bennett et al, 1987;Bennett & Jannetta, 1980).…”

“…"Trigeminal Evoked Potentials (TEP)" and "Quantitative sensory testing (QST)" (Kim et al, 2015) are examples of objective and non-invasive methods to measure peripheral neural function (Kim et al, 2015;Zhao et al, 2017), that may be used as an adjunct in the diagnostic process following trigeminal nerve injuries (Rosen, 2014;Fagade & Wastell, 1990;Bennett et al, 1987;Bennett & Jannetta, 1980;Barker et al, 1987).…”

“…Objective sensory tests (Kim et al, 2015;Agbaje et al, 2015) are aimed to avoid a possible bias from the subjectivity of the clinical sensory testing (Rosen, 2014;Fagade & Wastell, 1990;Bennett et al, 1987;Bennett & Jannetta, 1980;Agbaje et al, 2015;Barker et al, 1987).
