PubMed and Embase were searched for studies reporting BTX or DBS interventions for PS in PD patients. Outcomes included lateral trunk flexion (LTF) angle, pain scores, and clinical scales assessing posture. Risk of bias was assessed using RoB\u20102, ROBINS\u2010I, and JBI tools. Meta\u2010analyses were performed using random\u2010effects models for BTX\u2010related outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Sixteen studies comprising 113 patients with PD and PS were included. Of these, 96 patients received BTX injections and 17 underwent DBS.

Among the 17 patients treated with DBS, 14 received subthalamic nucleus (STN) stimulation, and the remainder underwent PPN or GPi targeting. Improvement in trunk posture was observed in 13 (76%) DBS cases.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This review finds that BTX injections are safe and effective for managing PS in PD, showing consistent, although modest, benefits in reducing posture abnormalities and pain.
