Effects of local anaesthetics (neural therapy) on pain and hand functions in patients with De Quervain tenosynovitis: A prospective randomised controlled study.

OBJECTIVE: De Quervain tenosynovitis is the most common cause of lateral wrist pain. The diagnosis can be made with the Finkelstein test when pain is provoked with wrist ulnar deviation. Conservative treatment including rest, non-steroidal anti-inflammatory medication and physical therapy is applied first, then there may be a need for corticosteroid injections, and in resistant cases, surgery. The aim of this study was to evaluate the effectiveness of neural therapy (NT) on pain and hand functions in patients with De Quervain tenosynovitis. METHODS: A total of 36 patients admitted between May 2019 and March 2020 were randomly assigned to neural therapy (NT) and control groups. Hand rest and thumb spica splint were applied to all the patients, and NT interventions to the NT group only. A visual analogue scale (VAS) and the Duruöz Hand index (DHI) were used to measure pain and functionality at baseline, then at 1 and 12 months after the end of the treatment. RESULTS: The NT and control groups both showed improvements in VAS and DHI scores at 1 and 12 months compared with baseline (P < .001) according to within group comparisons. The VAS scores were significantly lower at both 1 and 12 months compared with baseline in the NT group (P < .001, P = .002 respectively). The DHI scores were lower in the NT group at 1 month (P = .009), and at 12 months there was no significant difference between the two groups (P = .252). No adverse effects were seen in any patient. CONCLUSION: NT seems to be effective in reducing pain and improving hand functions in patients with De Quervain tenosynovitis.

Sacroiliac Joint Dysfunction Treated Using Neural Therapy to the Temporomandibular Joint: A Case Report.

Temporomandibular joint disorders (TMJD) include temporomandibular joint dysfunction and bruxism. Sacroiliac joint dysfunction (SJD) is a frequent cause of non-discogenic low back pain. Studies suggest a relationship between TMJD and SJD; however, the link remains unclear. Neural therapy (NT) utilises local anaesthetic injections to treat pain by normalising a dysfunctional autonomic nervous system held responsible for initiating or propagating chronic pain. A 31-year-old female presented with a 1-year history of mechanical left-sided low back pain and sleep bruxism. Examination revealed crepitation of the left TMJ and a trigger point in the masseter muscle. Range of motion of the spine and hip joints were normal, Patrick and Geanslen tests were positive on the left side. Spine and standing flexion tests were also positive. Magnetic resonance imaging of the lumbar spine and sacroiliac joints were normal. A diagnosis of SJD was made, and the patient was treated using NT. Injections of lidocaine 0.5% to the left TMJ, the masseter muscle and intradermal segmental injections at the level of C4 were administered. The patient's back pain and TMJ tenderness reduced and continued so throughout the 3-month follow-up period. SJD may be related to TMJD, and NT may be used in its treatment.
