“…The authors reported a modest positive effect of functional bracing at 8 to 12 weeks with improved visual analogue scale in the braced group versus unbraced group ( p = 0.047). 46 The majority of the braced group reported a positive effect of bracing as it pertained to their rehabilitation at 8 and 12 weeks postinjury (8 weeks: 79%; 12 weeks: 82%). Most of the braced group also reported improved stability with the brace at 8 and 12 weeks postinjury (8 weeks: 95%; 12 weeks: 90%).…”

Anterior cruciate ligament (ACL) injuries and surgeries are both increasing in incidence. A notable rate of reinjury and failure does occur after ACL surgery. As a result, interventions that may reduce ACL injury or reinjury are needed and are active areas of innovation. Knee bracing as a strategy to either prevent primary ACL injury, reduce reinjury, or failure after ACL surgery is common. The evidence for bracing around ACL injuries is not straightforward. Clinicians therefore need to understand the relevant literature on bracing around ACL injuries to make personalized decisions for individuals who may be at risk for ACL injury. The purpose of this review is to provide an overview on bracing for ACL injuries and summarize the current available clinical evidence for its use in ACL injuries.

“…In addition, the learning phenomenon was limited with the 4 trials and with the randomization of the running order of each condition. This also eliminates learning bias [10,17,18]. The nuance that can be brought to the results in the literature comes from the type of brace, knee brace or compression applied, as there are different types of compression: degressive, progressive, selective or constant.…”

Purpose:The purpose of this study is to evaluate the effect of an innovative prophylactic knee orthosis on postural balance. This prophylactic knee orthosis is designed with a compression that is oriented in a chosen direction. The purpose of this compression is to improve stability in dynamic situations. Orthoses are used to provide functional improvements to knee problems. However, more scientific validation is needed for this type of product.Methods: 20 sportsmen in team sports performed a functional test: the Y-Balance Test. This reliable and reproducible test allows to evaluate the postural balance of the lower limb. The subjects were tested in 3 conditions: prophylactic orthosis with innovative compression, control orthosis (with no compression) and without orthosis. The average of the three trials were collected in each direction and condition. Results:The prophylactic orthosis had a better standardized score in the anterior direction (p<0.05) and a better composite score (p<0.05) than the control orthosis (no compression). However, there were no differences in the normalized score in the other directions. There were no significant differences between the prophylactic orthosis and without orthosis. Conclusion:Wearing the prophylactic orthosis improves postural balance compared to a orthosis with no compression. But there is no difference between the prophylactic orthosis and without orthosis on postural balance.

“…In relation to the kinematic changes in knee transverse plane motion with the use of orthosis and their restrictive effects on knee movements have been well documented. 21,28,29 The sit-to-stand task demonstrated that when the orthotic knee joint transverse DOF was locked (the brace set to the one-DOF condition), the mounted load cell behind the joint detected a mean load of as much as 41 Newtons. The main reason for this load may be due to a mismatch between the orthotic movement pattern and the anatomic joints.…”

Objectives: Knee bracing as a conservative treatment option for patients with medial knee osteoarthritis (KOA) is of great interest to health practitioners and patients alike. Optimal orthotic knee joint structure is essential to achieve biomechanical and clinical effectiveness. Therefore, this study aimed to identify the effects of a knee orthosis with a new two-degrees-of-freedom (DOF) joint design on selected gait parameters and in a sit-to-stand task in patients with mild-to-moderate medial KOA. Methods: This study was conducted both at the Physical Medicine and Rehabilitation Clinic in Shahid Modarres Academic Hospital and the Biomechanical Laboratory of Rehabilitation Faculty of Iran University of medical Sciences in Tehran, Iran from September 2015 to October 2017. The gait performance of 16 patients was assessed without an orthosis, using a common one-DOF (DOF) knee orthosis and using the same knee orthosis with a two-DOF orthotic joint design. The interactive shearing force between limb and brace in the shell area during a sit-to-stand test was also identified. Repeated measures analysis of variance was used to analyse the data. Results: Compared with walking with no orthosis, both orthosis conditions reduced the external knee adduction moment significantly (P ≤0.05). A significant increase between the one-DOF and two-DOF conditions in terms of walking speed (P = 0.041 and P = 0.009, respectively) and stride length (P = 0.028 and P = 0.038, respectively) was observed. In a sit-to-stand test, wearing the orthosis significantly decreased knee transverse plane range of motion (P ≤0.05). There was a 41.31 ± 8.34 Newtons reduction in knee flexion constraint force. Conclusion: The two-DOF knee orthosis was more comfortable compared to the one-DOF knee orthosis during deep knee flexion. Otherwise, the one- DOF- and two-DOF-braces performed similarly.
