Background:
Postural deformities, such as Pisa syndrome (PS), and camptocormia and antecollis (C&A) are common in patient with Parkinson's disease (PwPD). These deformities can lead to back disability and pain with different mechanisms, including abnormal loading or stress on soft tissues as muscles, lumbar discs and ligaments.
Objectives:
To evaluate the effect of different postural deformities including PS and C&A on back function and pain in PwPD.
Methods:
The function, disability and pain were assessed by Oswestry disability index (ODI) and brief pain inventory (BPI). All participants completed clinical assessments by the Unified Parkinson's Disease Rating Scale (UPDRS), Modified Hoenh & Yahr (mH&Y) staging and the Levodopa Equivalent Daily Dose (LEDD).
Results:
PS and C&A groups significantly showed worse disability ODI and pain BPI, and higher LEDD and mH&Y stage compared with PD groups. However, no differences were found in PD duration and UPDRS in the same groups. Moreover, no differences were observed between PS and C&A groups in the mentioned scales.
Conclusion:
These results demonstrated that PS and C&A are associated with severe impairment of back functions and pain. Rehabilitation programs for PwPD and PS, and C&A should include spine alignment and postural training.
