1. An adjustable scoliosis orthosis comprising:
an orthosis body configured to be worn around a user's torso, the orthosis body having an inner surface shaped to conform to the user's torso and an opening configured to allow the torso to enter and exit;
a connecting mechanism arranged across the opening for selectively securing and adjusting a fit of the orthosis around the torso; and
an adjustable pressure system comprising:
an annular airbag assembly positioned within the orthosis body and configured to apply localized corrective pressure to targeted regions of the user's torso; and
a pressure adjustment mechanism comprising a pressing rod extending through a connecting seat fixed to the orthosis body, the pressing rod having a press disc at one end, wherein the annular airbag assembly is sleeved on the pressing rod and positioned between the press disc and the orthosis body,
wherein the pressing rod is adjustable to vary a position of the press disc relative to the annular airbag assembly, thereby altering an internal volume and pressure of the annular airbag assembly to provide adjustable, localized corrective force on the user's torso,
wherein the annular airbag assembly further comprises an inflation end configured to allow adjustment of the internal volume within the annular airbag assembly; and
wherein the inflation end of the annular airbag assembly is provided with a valve mechanism to allow a controlled inflow and outflow of gas to the annular airbag assembly.
