Acute Effects of Interferential Current on Edema, Pain and Muscle Strength in Patients With Distal Radius Fracture

Not Applicable

Completed

• Conditions: Radius Fractures; Edema; Pain
• Interventions: Device: Electrotherapy, interferential current; Other: Control

• Registration Number: NCT03438864
• Lead Sponsor: Ege University

Brief Summary

Interferential current is a form of electrotherapy that is obtained by placing two different plates that produce medium frequency waveform current, resulting in a low frequency interferential waveform in deeper tissues. It was shown interferential current electrotherapy is beneficial for reduction of traumatic edema in tissues and pain control.

Patients with conservatively managed distal radius fractures were recruited after casts are shed, and were treated with one session(30 minutes) of different protocols of interferential current electrotherapy. Before and after therapy, they were evaluated with volumetry, hand grip strength and visual analogue scale for pain.

Arm && Interventions

Group	Intervention	Description
100 Hz	Electrotherapy, interferential current	Interferential current, entry frequency 4000 Hz and 4100 Hz, beat frequency 100 Hz, amplitude was individualized and increased until patients felt a comfortable tickling sensation.
10 Hz	Electrotherapy, interferential current	Interferential current, entry frequency 4000 Hz and 4010 Hz, beat frequency 10 Hz, amplitude was individualized and increased until patients felt a comfortable tickling sensation.
Placebo-Sham Control	Control	No current except for first 5 seconds, device open but does not appy electrotherapy.

Primary Outcome Measures

Name	Time	Method
Volumetry	30 minutes	Patients were asked to dip their hands slowly into a special bucket full of water with volume markings until their middle finger touched to the bottom of the bucket. The spilled amount of water were measured as milliliters.
Visual Analogue Scale	30 minutes	Patients were asked to express their discomfort level from pain in a scale ranging from 1 to 10(with the help of a 10 cm line), and point they showed were measured as millimeters.
Hand Grip Strength	30 minutes	Patients were asked to use a hydraulic hand dynamometer for hand grip strength in a position of 10 to 30 degrees of wrist extension, and results were registered as kilograms.
