- Brief Summary
Brachial plexus neuropathies, specifically of the median, radial, ulnar, suprascapular, axillary and dorsal scapular nerves, can arise when a peripheral nerve trunk or nerve root is subjected to injury, compression, inflammation or ischemia, resulting in reduced physical capabilities of the peripheral nervous system. Although pharmacological treatments provide mild symptomatic relief in the short term, they are not without side effects.
Neurostimulation techniques may be an effective treatment option for peripheral brachial plexus neuropathies. Some of these procedures are transcutaneous electrical nerve stimulation (TENS) or percutaneous electrical nerve stimulation (PENS). Although some case series have documented a positive effect in relation to ultrasound-guided PENS for subjects with subacromial pain syndrome or postsurgical pain, the lack of studies, to our knowledge, analyzing the effects of percutaneous electrical nerve stimulation, in relation to pain and paresthesias in subjects with brachial plexus neuropathy, warrants investigation for this goal.

- Primary Outcome Measures
Name Time Method Pain Detect Scale 10 minutes Screening questionnaire for neuropathic pain. This scale consists of a section dedicated to pain intensity and another that is responsible for assessing the qualitative aspect of pain, i.e., identifying whether the pain is of neuropathic characteristics. In the total of this scale the maximum possible score is 38 points and the minimum -1. For screening purposes, a score less than or equal to 12 is considered an unlikely neuropathic component. A score greater than or equal to 19 concludes that the neurological component in pain is probable.
Lanss Scale 10 minutes Useful to identify patients with a pain experience dominated by neuropathic mechanisms. It is based on the analysis of sensory description and exploration of sensory dysfunction at the patient's bedside. It consists of 7 items and is scored from 0 to 24. At a score of less than 12, the neuropathic component is considered unlikely. A score greater than or equal to 12 is considered probable neuropathic pain. It is a validated scale for patients with neuropathic pain.
Numerical Pain Rating Scale (NPRS) 1 minute A unique 11-point numerical scale validated in patients with various painful conditions. Data obtained through NPRS are easily documented, intuitively interpretable, and meet regulatory requirements for pain assessment and documentation. This scale is reliable and validated for assessing patients with pain20. Score 0 corresponds to "no pain" and score 10 corresponds to "maximum possible pain". In this study, patients were asked to mark their maximum pain detected in the last week (NPRS Max) and their minimum pain detected in the last week (NPRS Min).
- Secondary Outcome Measures
Name Time Method Neural stress test 5 minutes Nerves react to certain mechanical stresses and forces, but to establish positivity of such tests, the possibilities of "false positivity" due to other non-nerve structures must first be eliminated. The determination of a positive neural test is established by provocation and symptom relief techniques. In this outcome measure only a positive or negative test was considered. The test was positive if the patient's neural symptoms were reproduced during provocation, or negative if no such symptoms occurred.
DASH scale 5 minutes It is a validated scale for assessing upper limb functionality. It is an instrument that can be completed by the patient with the help of the physical therapist. It consists of 30 questions that assess certain symptoms, as well as the ability to perform activities, ranging from 1 to 5, with 1=no difficulty and 5=maximum difficulty. The higher the score, the greater the upper limb disability.
Thermography 10 minutes A thermal camera, HT-02D infrared thermographic and visible light camera with IR 1024 pixels and -20\~300°C, 6Hz refresh rate, infrared thermometer was used. The thermograph indicates the approximate temperature of the body segment to be examined by focusing it with the thermographic camera.
