Article Abstract

Background: This randomized controlled trial investigated the therapeutic effects of transcutaneous electrical acupoint stimulation (TEAS) on insomnia, negative emotions, and neurotransmitter levels in patients undergoing methamphetamine (METH) withdrawal.

Methods: We enrolled 84 eligible patients from the Kangxin Hospital of Guizhou Province, China (August 2023-December 2024), randomly allocating them to TEAS (n = 42) or sham-TEAS (n = 42) groups. The patients were divided into a TEAS group of 42 cases and a sham-TEAS group of 42 cases according to the randomized, single-blind and control principle. The 2 groups patients were given TEAS or sham-TEAS treatment for 45 minutes after treated with sleep health education. Interventions described above in weekdays were given once a day for 4 weeks, with a total of 4 consecutive weeks. The Pittsburgh Sleep Quality Index (PSQI), insomnia severity index (ISI), METH withdrawal symptom score, Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), serum levels of 5-hydroxytryptamine, noradrenaline, gamma-aminobutyric acid and dopamine of each group were compared before treatment, after treatment and in follow-up period.

Results: Baseline characteristics were comparable between groups (both P > .05). After 4 weeks of treatment, the scores of PSQI, ISI, METH withdrawal symptom, HAMA, HAMD in the TEAS group were significantly lower than those in the sham-TEAS group and the difference was statistically significant (both P < .001), serum levels of 5-hydroxytryptamine, gamma-aminobutyric acid and dopamine in the TEAS group were significantly higher than those in the sham-TEAS group, and serum levels of noradrenaline in the TEAS group were significantly lower than those in the sham-TEAS group (both P < .001). In follow-up period, the scores of PSQI, ISI, METH withdrawal symptom, HAMA, HAMD in the TEAS group were significantly lower than those in the sham-TEAS group, and the difference was statistically significant (both P < .001).

Conclusion: TEAS effectively improved insomnia, anxiety and depression after METH withdrawal, it is worth of clinical application and promotion while significantly affecting serum levels of neurotransmitters.

Background: Transcutaneous Electrical Nerve Stimulation (TENS) is established for chronic lower back pain but less studied in acute settings. This study evaluated the efficacy of cross-channel TENS for acute lower back pain in the emergency department (ED).

Methods: This single-blinded, randomized controlled trial enrolled ED patients aged 18-59 with acute lower back pain and Emergency Severity Index scores of 4 or 5.

Background: Chronic nonspecific neck pain (CNSNP) is a prevalent and complex condition. Although many studies have evaluated the effectiveness of transcutaneous electrical nerve stimulation (TENS), interferential current (IFC), therapeutic exercise (TE), and manual therapy (MT) individually, this study aimed to determine whether adding IFC and/or TENS to a Multimodal Therapeutic Intervention Program (MTIP) would produce better outcomes than the MTIP alone concerning functional capacity, pain intensity, pain catastrophising, kinesiophobia and overall perceived effect in individuals with CNSNP.

Methods: Seventy-five individuals with CNSNP were randomly assigned to one of three groups: MTIP, MTIP + IFC, or MTIP + TENS.

Phantom pain (PP) is a neuropathic pain syndrome that occurs after limb amputation and is perceived in the absent body part. Its exact pathophysiology remains unclear but involves peripheral nerve lesions, central sensitization, and cortical reorganization. Psychological and social factors also play a significant role in its manifestation.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and often persistent adverse effect of several anticancer agents, leading to impaired physical function and quality of life. Although exercise therapy and physical modalities such as transcutaneous electrical nerve stimulation have been reported to alleviate CIPN symptoms, the efficacy of alternating magnetic field therapy remains unclear. We here report a rectal cancer survivor who experienced difficulty returning to work due to persistent neuropathic symptoms of CIPN.
