Stimul 1340: a Medical Benchmark for the Study of Nociceptive Pathways
Deka's Stimul 1340 is an ND:YAG medical laser specifically designed for the stimulation of laser evoked potentials (LEPs), which have become an essential method in clinical neurophysiology. Unlike traditional electrical stimulation, which activates both large nerve fibres and small nociceptive fibres, the Stimul 1340 allows selective activation of nociceptors located in the superficial layers of the skin. This specificity ensures reliable recording of pain-related brain responses, making it an objective and reproducible diagnostic tool. The device is intended for medical and research teams wishing to accurately assess the integrity of nociceptive pathways, from the skin receptor to the cerebral cortex.
Clinical Applications and Medical Benefits
The Stimul 1340 is useful in many pathological contexts. It is particularly indicated for the investigation of neuropathic pain, whether related to peripheral neuropathy, myelopathy or central damage such as cerebral infarction. Its use has also been validated in complex chronic pain conditions such as fibromyalgia, migraine, trigeminal neuralgia and postherpetic pain. A few low-intensity pulses, felt by the patient as a slight prick, are sufficient to obtain reproducible evoked potentials. These objective data allow the clinician to analyse the latency and amplitude of brain signals, thus helping to differentiate peripheral dysfunction from central damage. Dozens of studies in international scientific literature have confirmed the effectiveness and reliability of lasers for analysing the nociceptive system, giving the Stimul 1340 unquestionable clinical legitimacy.
Technical Performance and Ergonomics at the Service of Clinicians
The Stimul 1340 stands out thanks to its combination of laser power and safety of use. Based on a ND:Yap crystal emitting at 1340 nm, it delivers controlled energy pulses capable of causing selective stimulation without interference from tactile fibres. Its 10-metre fibre optic transmission offers great flexibility, allowing different areas of the body to be stimulated, including the oral mucosa and hard-to-reach areas. The device is compatible with all types of electromyographs, making it easy to integrate into an existing clinical environment. Microprocessor control ensures high pulse reproducibility, precise parameter adjustment and a latency time of less than 20 µs. Compact and weighing only 40 kg, the Stimul 1340 is easy to install in hospital laboratories and specialised research centres.
