Shoulder Dysfunction in Parkinson's Disease: Implications of Motor Subtypes, Disease Severity, and Spinopelvic Alignment.

ABSTRACT:

Objective

To investigate shoulder function and muscle alterations in patients with Parkinson's disease (PD) and determine their associations with spinopelvic parameters and clinical status.

Methods

This prospective cohort study included 62 PD patients, divided into postural instability and gait difficulty (PIGD) (n=30) and non-PIGD (n=32) groups, as well as 35 controls. The American Shoulder and Elbow Surgeons (ASES) score, shoulder range of motion (ROM), and shoulder muscle stiffness were assessed for each group. Clinical demographics, PD severity, and shoulder-related parameters were extracted and analyzed.

Results

Compared with the control group, the PIGD group had significantly lower total and subscored ASESs (all p<0.05). Compared with the controls, both the PIGD
