Interferential electrical stimulation for improved bladder management following spinal cord injury

Area of Science:

• Neurology
• Urology
• Rehabilitation Medicine

Background:

• Neurogenic bladder (NB) is a significant complication following spinal cord injury (SCI).
• Current treatments for NB often lack efficacy, are invasive, or have side effects.
• There is a need for non-invasive, effective, and easily applicable treatments for SCI-induced NB.

Purpose of the Study:

• To evaluate the efficacy and safety of interferential medium frequency current electrical stimulation (IMFC ES) for managing neurogenic bladder in SCI patients.
• To compare IMFC ES combined with standard care versus standard care alone.

Main Methods:

• A study involving 332 SCI patients with NB dysfunction was conducted.
• The experimental group received IMFC ES in addition to standard care.
• Urinary management outcomes (volitional control, catheterization, post-voidance residuum (PVR), urine loss (LOSS)) were assessed using the American Spinal Cord Injury Association Impairment Scale (AIS).

Main Results:

• IMFC ES was found to be safe, with no adverse events reported.
• Significant reductions in PVR and LOSS were observed in patients with AIS levels B and C who received IMFC ES.
• No significant improvements were noted for patients with AIS level A.

Conclusions:

• IMFC ES is an effective and safe therapeutic option for neurogenic bladder in SCI patients with preserved sensation (AIS levels B and C).
• Patients with SCI and NB classified as AIS levels B and C are the primary beneficiaries of IMFC ES therapy.
• Further research may be warranted for patients with complete SCI (AIS level A).
