Feasibility of High-frequency Stimulation on Knee Pain : Based on investigation of Clinical Characteristics, User Needs and Usage Satisfaction According to Age Groups

Abstract

Purpose: This study investigated the feasibility of the newly-developed high-frequency stimulation based on investigation of clinical characteristics, user needs and usage satisfaction according to age groups. Methods: Thirty participants with knee pain were participated in the study. Each participant received the high-frequency stimulation over both knees over three times a week during a total of two weeks. We investigated each participants’ clinical characteristics, user needs and post-intervention usage satisfaction by newly modified questionnaires. Results: As a result, 93.3% of participants wanted to receive the home-based management using the highfrequency stimulation and more than 60% of participants experienced the pain relief after 2-week intervention period. The twenties and thirties reported the largest satisfaction scores (3.722±0.575) after the intervention than other age groups. Conclusion: We conclude that the high-frequency stimulation over both knee is feasible to reduce the knee pain as a home-based pain management tool, especially for the younger.
