NCT07590011

Brief Summary

This study aims to evaluate the effects of four-cell galvanic bath therapy on pain and balance in patients with diabetic distal symmetric polyneuropathy. Diabetic peripheral neuropathy is a common complication of diabetes that can lead to pain, sensory loss, and impaired balance. In this randomized controlled study, participants received either conventional rehabilitation alone or conventional rehabilitation combined with four-cell galvanic bath therapy. The intervention was applied over a 4-week period. Pain and balance outcomes were assessed using standardized clinical measures. The findings of this study may help determine the effectiveness of galvanic bath therapy as a supportive treatment option in patients with diabetic neuropathy.

Outcome Measures

Primary Outcomes (1)

  • Postural Stability (Stability Index) Measured by TecnoBody Prokin PK252

    Postural stability will be assessed using the TecnoBody Prokin PK252 device. The Stability Index parameter reflects postural sway based on center of pressure displacement. Higher values indicate poorer balance performance and reduced postural stability.

    Baseline (Week 0), Post-treatment (Week 4), and Follow-up (Week 12)

Secondary Outcomes (7)

  • Berg Balance Scale (BBS)

    Baseline (Week 0), Post-treatment (Week 4), and Follow-up (Week 12)

  • Functional Reach Test (FRT)

    Baseline (Week 0), Post-treatment (Week 4), and Follow-up (Week 12)

  • Timed Up and Go Test (TUG)

    Baseline (Week 0), Post-treatment (Week 4), and Follow-up (Week 12)

  • Single Leg Stance Test

    Baseline (Week 0), Post-treatment (Week 4), and Follow-up (Week 12)

  • Short-Form McGill Pain Questionnaire (SF-MPQ)

    Baseline (Week 0), Post-treatment (Week 4), and Follow-up (Week 12)

Study Arms (2)

Four-Cell Galvanic Bath Therapy + Conventional Rehabilitation

EXPERIMENTAL

Participants received four-cell galvanic bath therapy in addition to a conventional rehabilitation program. The rehabilitation program included range of motion, stretching, strengthening, balance, coordination, and endurance exercises. The intervention was applied for 4 weeks, three sessions per week, with each session lasting approximately one hour.

Device: Four-Cell Galvanic Bath TherapyOther: Conventional Rehabilitation

Conventional Rehabilitation Alone

ACTIVE COMPARATOR

Participants received a conventional rehabilitation program consisting of range of motion, stretching, strengthening, balance, coordination, and endurance exercises. The program was applied for 4 weeks, three sessions per week, with each session lasting approximately one hour.

Other: Conventional Rehabilitation

Interventions

Four-cell galvanic bath therapy was applied using a direct current (1.5 mA) delivered through water-filled electrodes to both upper and lower extremities for 20 minutes per session, three times per week for 4 weeks.

Also known as: Four-Cell Galvanic Bath, Galvanic Bath Therapy
Four-Cell Galvanic Bath Therapy + Conventional Rehabilitation

A standardized rehabilitation program including range of motion, stretching, strengthening, balance, coordination, and endurance exercises, performed 3 times per week for 4 weeks, with each session lasting approximately 60 minutes.
