A forward head position correction collar is provided which includes a shoulder collar assembly, a chin mastoid piece； a cheek or jaw piece； and interconnecting means for interconnecting the chin piece to the collar assembly as to enable the chin piece to be manually and preferably incrementally adjustable with respect to the shoulder collar assembly in a Z- direction to thereby adjust the supported head of the wearer from the forward head position to an increasingly corrected position. The interconnecting means is further adapted for displacing the chin-mastoid piece in a vertical direction with respect to the shoulder collar assembly simultaneously with and proportional to the incremental adjustment of the chin-mastoid piece along the Z-axis. The correction collar may further include a lordosis correction assembly secured to the rear of the collar and engageable with the rear of the wearer for applying corrective forces to at least one or more of the cervical vertebrae of the wearer.
