Staging tools, such as the Movement Disorder Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), are useful for assessing the progression of PD.1,3

The MDS-UPDRS consists of four parts, two of which focus on activities of daily living (ADL).1

(1)‘Non-motor ADL’ assesses the impact of non-motor symptoms on the patient’s ability to carry out everyday activities independently.1 It assesses problems relating to cognitive function, sleep, mood, psychosis, fatigue, constipation, and urinary problems.1

(2)‘Motor ADL’ assesses the impact of motor symptoms on the patient’s ability to carry out everyday activities independently.1 It assesses problems relating to speech; chewing and swallowing; eating; dressing; hygiene; handwriting; hobbies and other activities; turning in bed; tremor; getting up from a bed or deep seat; walking and balance; freezing; and falls.1

(3)‘Motor examination’ is a clinical assessment of motor function, including speech, muscle rigidity, facial expression, hand and leg movements, toe and finger tapping, gait, tremor, and posture.1

(4)‘Motor complications’ covers the presence and severity of motor complications, such as fluctuations, OFF-state dystonia, and other dyskinesias.1
