Learning Objectives At the end of this presentation, I will: Understand the scientific justification for using rating scales in your Cameroon neurological practice for Parkinson’s disease Use the Hoehn and Yahr Stages for categorizing patients and the MDS-UPDRS for measuring severity in Parkinson’s disease Access available educational resources through the Movement Disorder Society

What do scales do for a clinician? Scales provide a numeric code for a sign or symptom Can indicate Presence (1) or Absence (0) Can indicate Severity 0-absent 1-minimal 2-mild 3-moderate 4-severe
Usual primary measures Motor Tremor Bradykinesia Rigidity Gait and balance Non-motor Depression Cognition
Scale requirements Three key attributes are needed for a good scale. Validity Reliability Responsivity Ideally, tested and validated in the given culture Training is necessary so that scales are used uniformally

Hoehn and Yahr Stages Developed in the 1960’s Describes categories overall impairment Patients do not necessarily progress sequentially across all stages Internationally respected as a means of immediate global communication on patients with PD
Hoehn and Yahr Stages 0—no parkinsonism 1—Unilateral involvement only 2—Bilateral involvement; normal balance 3—Mildly impaired postural reflexes, but disability is mild or moderate 4—Postural reflexes significantly impaired— disability marked, walking not safe 5—Confined to chair or bed—no safe standing
Patient examples Extracted from Common Movement Disorders: Video educational program Harold L. Klawans, Christopher G. Goetz and Caroline M. Tanner Raven Press 1990.
Hoehn and Yahr Stages
Important points In speaking with colleagues internationally, the Hoehn and Yahr stage immediately communicates an overall picture of parkinsonism Whereas Stages 2-5 represent progressive disability, Stage 1 is not necessarily less impaired than Stage 2. With levodopa available, most patients at any one time are Stage 2 and Stage 3 If a patient has had symptoms of parkinsonism for less than 2 years and is Stage 3, rethink the diagnosis.

MDS-UPDRS Designed to be a comprehensive rating of PD To cover Motor and non-Motor elements Fully validated in English version Several languages also available
MDS-UPDRS I: Non-motor Experiences of Daily Living 13 items: Interview (6) Questionnaire (7) II: Motor Experiences of Daily Living 13 items all patient questionnaire III: Motor Section - 18 items by examiner IV: Motor Complications 6 items: Interview: dyskinesias (3); fluctuations (3) Total: 50 Items (65 scores)
MDS-UPDRS Detailed instructions All scores are anchored to clinical statement: 0 = normal 1 = slight 2 = mild 3 = moderate 4 = severe Official Appendix for additional focus
MDS-UPDRS I. I. NON-MOTOR ASPECTS OF EXPERIENCES OF DAILY LIVING (nM-EDL) INTERVIEW QUESTIONNAIRE 1. COGNITVE IMPAIRMENT 1. SLEEP 2. HALLUCINATIONS 2. STAYING AWAKE 3. DEPRESSED MOOD 3. PAIN/SENSORY 4. ANXIOUS MOOD 4. URINARY FUNCTION 5. APATHY 5. CONSTIPATION 6. DOPAMINE 6. LIGHTHEADEDNESS DYSREGULATION ON STANDING 7. FATIGUE
MDS UPDRS II. MOTOR ASPECTS OF EXPERIENCES OF DAILY LIVING (M-EDL) — all part of questionnaire 1. Speech 8. Other fine motor tasks 2. Handling saliva 9. Tremor impact on activities 3. Swallowing & chewing 10. Turning in bed and 4. Feeding adjusting bed clothes 5. Dressing 11. Getting in and out of bed, 6. Hygiene car or deep chair 5. Dressing 12. Balance and walking 7. Handwriting 13. Gait Freezing
MDS UPDRS III. MOTOR EXAMINATION: 1. Speech10. Gait 2. Facial Expression11. Freezing of Gait 3. Rigidity 12. Postural Stability 4. Finger Tapping13. Posture 5. Hand Movements 14. Body Bradykinesia 6. Pronation-supination15. Postural Tremor of Hands 7. Toe Tapping 16. Kinetic Tremor of Hands 8. Leg Agility 17. Rest Tremor Amplitude 9. Arising from chair 18. Rest Tremor Consistency
MDS UPDRS IV. MOTOR COMPLICATIONS: A. DYSKINESIAS [exclusive of OFF-state dystonia] 1. Time spent with dyskinesias 2. Functional impact of dyskinesias 3. Painful off-state dystonia B. MOTOR FLUCTUATIONS 3. Time spent in the off state 4. Functional impact of fluctuations 5. Complexity of motor fluctuations
Instructions Written instructions provided for uniformity and clarity of application These instructions will be reinforced in Teaching Tape Overview description on methodology Item by item instructions
Interviewing patient/caregiver Complex questions on behavior and motor complications Present the concept being assessed Ground rules: Usual, most of the time Past week Options Any problem? (0) If yes, start with option 2 Work up or down Confirm

Questionnaire 20 questions (non-motor and motor experiences of daily living) 7 th grade reading level Source: Patient, Patient + caregiver, caregiver only Rater can explain, but not answer the questions
Questionnaire
Motor Objective evaluation (Part III) Instructions provided for testing methods Rater indicates On or OFF state If on levodopa, notes time of last dose All items are anchored with 0: normal 1: Slight 2: Mild 3: Moderate 4- Severe
