Objectives To investigate the construct validity of Trunk Impairment Scale (TIS), which was developed to assess trunk impairment in patients with stroke, Parkinson’s disease (PD). Design This retrospective, cross-sectional study enrolled consecutive PD inpatients. Correlation analysis performed clarify whether TIS assessment related other balance functions, lower extremity muscle strength, or walking ability. Factor see how background factors differ from function, limb and Results Examining data 471 PD, there were relationships between Mini-Balance Evaluation Systems Test ( r = 0.67), Barthel Index 0.57), general extension torque 0.51), two-minute walk test 0.54), Hoehn Yahr stage −0.61), Movement Disorder Society Unified Disease Rating part III total points −0.59). showed that items divided into three (an abdominal muscles righting reflex component; a perception verticality rotational component), differing scales included clinical items. Conclusion The can be useful for assessing underlying as basis activities daily living, gait ability PD.
