Abstract

This study aimed to examine whether worsening of postural deformities is seen in Parkinson's disease (PD) patients who exhibit the behavioral disorders punding or hobbyism (P-H), which involve maintaining the same poor posture. The subjects were 80 patients with PD (aged 73.1 ± 8.8 years; duration of disease, 6.4 ± 5.5 years). Using the Japanese-language version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease (J-QUIP), a group with P-H alone (P-H only group) and a group without impulsive-compulsive behaviors (non-ICB group) were compared with respect to the angles of forward and lateral trunk flexion while standing at rest. The group with ICBs (ICB group) identified by the J-QUIP consisted of 36 patients (45.0%). Of these, 25 (31.3%) were in the P-H only group. The non-ICB group, who were negative on all items of the J-QUIP, consisted of 44 patients (55.0%). Significantly higher values were seen in the P-H only group compared with non-ICB group for the angle of forward flexion of the trunk (FFT angle, p = 0.04), Unified Parkinson's Disease Rating Scale (UPDRS) part II score (p = 0.002), and UPDRS total score (p = 0.007). The FFT angle was increased and activities of daily living decreased in PD patients with P-H.
