About

ProtonicsTM Knee brace has been suggested as an intervention for patients with patellofemoral pain syndrome (PFPS). However, the effectiveness of this knee brace compared to traditional conservative methods knee rehabilitation is lacking. The objective of this randomized controlled trial was to compare the effect of ProtonicsTM knee brace vs. sports cord on knee pain and function in patients with PFPS.

Full description

The purpose of this graduate student research study was to compare the effect of ProtonicsTM knee brace vs. sports cord on knee pain and function in patients with PFPS.

Design: Randomized controlled trial.

Setting: Loma Linda University.

Participants: Subjects with patellofemoral pain will participate in the study.

Intervention: Subjects will be randomized to one of two treatment groups, the ProtonicsTM knee brace or the sport cord to complete a series of resistance exercises over the course of 4 weeks.

Main Outcome Measures: Both groups will be evaluated according to the following clinical outcomes: Anterior pelvic tilt (APT), hip internal/external rotation, and iliotibial band flexibility. The following functional outcomes were also assessed: Global Rating of Change (GROC) scale, the Kujala score, the Numeric Pain Rating Scale, and the lateral step-down test.

Enrollment: 43 patients

Sex: All

Ages: 18 to 45 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Subjects will be males and females who have Patellofemoral pain symptoms for more than 1 month, have pain level ≥ 3 on a Numeric Pain Rating Scale, and pain during at least 2 activities, such as squatting, ascending/descending stairs, and/or running.

Exclusion criteria

• Subjects will be excluded if they have previous traumatic injuries to the knee joint/lower limbs, sign, and symptoms of meniscus tear or ligamentous-related pathology, neurological disorders and being on pain medication."
