Pulsed Radiofrequency

To investigate the efficacy and safety of the application of PRF combined PRP to the for the treatment of GPN.

this study aims to assess the role of pulsed radiofrequency of the brachial plexus or pulsed radiofrequency of shoulder individual nerves in the management of post-mastectomy shoulder pain.

Lomber dorsal root ganglion pRF is an interventional treatment options in the treatment of lumbar radicular pain. The goal of this study is to investigate the effect of sensory threshold outcomes on pain severity during dorsal root ganglion pulsed radiofrequency (DRG-pRF). It will also learn effects about disability due to chronic LRP. The main questions it aims to answer are: Does lower sensory threshold result in lower pain scores and chronic LRP related disability? Participants will: Take DRG-pRF procedure for 4 minutes. Visit the clinic at 1. and 3. month for questionnaries.

Chronic shoulder pain due to impingement syndrome and supraspinatus tendinosis is a debilitating condition. Suprascapular nerve innervates most part of shoulder joint. Supraspinatus nerve block can be used as a part of pain therapy. However, its efficacy is short-lasting. To prolong analgesia, short bursts of electrical stimulation to suprascapular nerve may be applied. To the date there is no consensus about duration of these type of stimulation. Investigators' aim is to investigate efficacy of two different duration of stimulation (pulsed radiofrequency) on chronic shoulder pain.

Patients with pudendal neuralgia suffer from long-term pain, which severely affects their quality of life. Due to unclear etiology, there is a lack of specific treatment methods. The aim of this study is to evaluate the efficacy of combined pulsed radiofrequency with ganglion impar block therapy helps evaluate the effectiveness of this treatment method for pudendal neuralgia, comparing it with traditional treatments or single interventions, and providing guidance for clinical practice.

The management of chronic lumbar radicular and neuropathic pain is complex and the treatment success rates are low. Pulsed radiofrequency (PRF) has been described in these cases. In order to determine whether high-voltage PRF show better results than PRF a prospective, doble-blinded and randomized study is conducted in patients with chronic lumbar radicular and neuropathic pain.
