Shortwave Intervention for Diabetic Peripheral Neuropathy.

16. juni 2026 opdateret af: Cheng Qing-feng, Chongqing Medical University

Shortwave Intervention for Diabetic Peripheral Neuropathy: A Randomized, Single-Blind, Sham-Controlled Trial(SIDPN)

This study is a single-center, randomized, single-blind, sham-controlled clinical trial aimed at evaluating the efficacy and safety of shortwave therapy administered for five consecutive days in the treatment of diabetic peripheral neuropathy. The study plans to enroll 202 patients, who will be randomly assigned in a 1:1 ratio to either the shortwave therapy group (20 minutes daily for five consecutive days) or a sham treatment group with an identical appearance. The primary efficacy endpoint is the remission rate of the Toronto Clinical Scoring System score one month after treatment (a decrease of ≥1 point). Secondary endpoints include short-term efficacy, pain visual analog scale scores, quality of life scores, and safety indicators. The study hypothesizes that shortwave therapy can significantly improve neurological symptoms, with an expected remission rate of 65% in the treatment group and 20% in the control group, with the superiority margin set at 20%. This study will provide high-quality evidence-based medical evidence for the use of shortwave therapy in diabetic peripheral neuropathy.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Sham-komparator: Placebo treatment group
Using devices that are completely identical in appearance, the treatment process, screen display, and sounds are the same as the active group, but the devices are specially modified and do not emit electromagnetic energy. To ensure the success of blinding, the skin temperature of the treatment area will be measured before and after treatment, but the specific values will not be disclosed to the subjects.

Eksperimentel: Shortwave therapy group
Using the CJ270-I model shortwave therapy instrument from Nanjing Congjing Biological Machinery Co., Ltd. Patients took a sitting position, placed both lower limbs into the therapy instrument, adjusted the power to 250W, frequency to 27.12MHz, once daily, 20 minutes each time, for 5 consecutive days.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Remission rate of TCSS score
Tidsramme: From enrollment to the end of 4 weeks of treatment
The Toronto Clinical Scoring System (TCSS) assesses neuropathy symptoms, sensory deficits, and reflexes, with a total score ranging from 0 to 19. Higher scores indicate worse outcomes (more severe neuropathy). Remission is defined as a decrease of 1 point or more from baseline. This outcome is compared between the shortwave therapy group and the sham treatment group.
From enrollment to the end of 4 weeks of treatment

Changes in each component of TCSS compared to baseline
Tidsramme: Within 5 days and 1 month after treatment
Changes in each component of the Toronto Clinical Scoring System (TCSS) from baseline. The TCSS assesses three components: symptoms, sensory deficits, and reflexes. Total score range: 0 to 19 Each component has its own sub-score range (symptoms: 0-6, sensory: 0-5, reflexes: 0-8) Higher scores indicate worse outcomes (more severe neuropathy) This outcome measures the within-group change from baseline at each follow-up time point.
Within 5 days and 1 month after treatment
Change in VAS pain score from baseline
Tidsramme: Within 5 days and 1 month after treatment
Visual Analogue scale（VAS）Score range: 0-10 Higher scores indicate worse outcomes (more severe pain) This outcome measures the within-group change from baseline at each follow-up time point.
Within 5 days and 1 month after treatment
Change in EQ-5D quality of life score from baseline
Tidsramme: Within 5 days and 1 month after treatment
Changes in the EuroQol Five-Dimensional Five-Level Questionnaire (EQ-5D-5L) from baseline. The EQ-5D-5L consists of two components: 1. Utility index score: Derived from the 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) Score range typically from ≤ 0 (worst health state) to 1 (full health) Higher scores indicate better outcomes 2. EQ-VAS (Visual Analogue Scale): Self-rated overall health on a vertical scale Score range: 0 (worst imaginable health) to 100 (best imaginable health) Higher scores indicate better outcomes This outcome measures the within-group change from baseline at each follow-up time point.
Within 5 days and 1 month after treatment
Patient Global Impression of Change (PGIC)
Tidsramme: Within 5 days and 1 month after the treatment
Patients' self-assessment of overall change in their condition since the start of treatment, measured by the Patient Global Impression of Change (PGIC) scale. The PGIC is a 7-point rating scale: Score range: 1 to 7 Scoring: 1 = Very much better 2 = Much better 3 = A little better 4 = No change 5 = A little worse 6 = Much worse 7 = Very much worse Lower scores indicate better outcomes (greater improvement)
Within 5 days and 1 month after the treatment
