Trial Outcomes & Findings for Transcutaneous Electrical Nerve Stimulation After Total Knee Arthroplasty. (NCT NCT03046225)

NCT ID: NCT03046225

Last Updated: 2018-03-22

Results Overview

It was measured by Visual Analogue Pain Scale (VAS), which has scores ranging from zero (which means "no pain") to 10 (which means "worst possible pain"). Two evaluations of the pain level were performed in each group, before and after the interventions.

SECONDARY outcome

Timeframe: 24 hours

It was evaluated based on the information found in patients' electronic records, considering whether they received morphine during the 24 hours following the interventions or not.

8 Participants

SECONDARY outcome

Timeframe: 30 minutes

It was extracted from the continuous passive movement device display. During the use of the continuous passive movement device (CPM), from the observation of the digital display in its control, the degrees of amplitude reached in the passive movements of flexion and extension of the knee submitted to the surgery were extracted.
