* Bottom line: A trial of counterforce bracing
should be used if pain precludes active rehabilitation or vocational pursuits, but should not be used as the sole therapy.

They arrive to similar conclusions: there are some data suggesting that bracing
may be effective preventing and reducing severity of MCL injuries, but there is no conclusive evidence for PKB decreasing the rate or severity of ACL injuries in football players (1, 33, 34).

In the present study, a finite element numerical method has been used to model the frames and evaluating the nonlinear response of belt braces has been applied as a lateral bracing
A total of 242 patients were included in the primary analysis: 51 patients assigned to back bracing
, 65 assigned to observation, 88 who chose back bracing
, and 38 who chose observation.
During a discussion of the study, an attendee said that in her practice she avoids using the type of brace used in the study with a cutout over the knee in younger patients with PF pain, because of data suggesting that bracing
compresses the patella and increases the contact area between the patella and the trochlear notch, thereby increasing stress rather than changing the patella position or movement.

As Blake once said: "Damn braces, Bless relaxes." Or in an echo from Frankie Goes to Hollywood: "Relax, don't do it." The truth is that bracing
yourself to prepare for some possibly unpleasant event that may never happen simply doesn't work.
The most widely used method to assess the efficacy of knee bracing
in-vivo has been the arthrometry test in which a device is externally strapped to the lower leg and the tibial translation is recorded during anterior shear loading (Beck et al., 1986; Branch et al., 1988; Colville et al., 1986; Mishra et al., 1989; Rink et al., 1989; Risberg et al., 1999).
