An external spinal brace system, comprising: a plurality of support mechanisms, comprising: a first support mechanism, comprising: a first coupling portion at a first end of the first support mechanism; a first coupling opening at a second end of the first support mechanism, wherein the second end is opposite to the first end of the first support mechanism; and a second support mechanism, comprising: a second coupling portion at a third end of the second support mechanism; a second coupling opening at a fourth end of the second support mechanism, wherein the fourth end is opposite to the third end of the second support mechanism; wherein the first support mechanism is couplable, during use, to the second support mechanism such that the first and second support mechanisms (110a,110b) are inhibited, during use, from decoupling; a coupling system coupling the plurality of support mechanisms to a subject such that the plurality of support mechanisms are positioned, during use, along at least a portion of the subject's spine; characterised in that the external spinal brace system includes a resilient member (200a, 200b, 200c) that provides a positive distraction force between each support mechanism; such that the plurality of support mechanisms apply a posterior distraction force to the subject. a plurality of support mechanisms, comprising: a first support mechanism, comprising: a first coupling portion at a first end of the first support mechanism; a first coupling opening at a second end of the first support mechanism, wherein the second end is opposite to the first end of the first support mechanism; and a second support mechanism, comprising: a second coupling portion at a third end of the second support mechanism; a second coupling opening at a fourth end of the second support mechanism, wherein the fourth end is opposite to the third end of the second support mechanism; wherein the first support mechanism is couplable, during use, to the second support mechanism such that the first and second support mechanisms (110a,110b) are inhibited, during use, from decoupling; a first support mechanism, comprising: a first coupling portion at a first end of the first support mechanism; a first coupling opening at a second end of the first support mechanism, wherein the second end is opposite to the first end of the first support mechanism; and a first coupling portion at a first end of the first support mechanism; a first coupling opening at a second end of the first support mechanism, wherein the second end is opposite to the first end of the first support mechanism; and a second support mechanism, comprising: a second coupling portion at a third end of the second support mechanism; a second coupling opening at a fourth end of the second support mechanism, wherein the fourth end is opposite to the third end of the second support mechanism; a second coupling portion at a third end of the second support mechanism; a second coupling opening at a fourth end of the second support mechanism, wherein the fourth end is opposite to the third end of the second support mechanism; wherein the first support mechanism is couplable, during use, to the second support mechanism such that the first and second support mechanisms (110a,110b) are inhibited, during use, from decoupling; a coupling system coupling the plurality of support mechanisms to a subject such that the plurality of support mechanisms are positioned, during use, along at least a portion of the subject's spine; characterised in that the external spinal brace system includes a resilient member (200a, 200b, 200c) that provides a positive distraction force between each support mechanism; such that the plurality of support mechanisms apply a posterior distraction force to the subject.
