1. Rating Scales for Parkinson’s Disease African and Telemedicine Initiatives Movement Disorder Society Cameroon Christopher G. Goetz, Chicago, USA

2. 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

3. Outline Overview of scale usage in Movement Disorders Review of two primary scales Hoehn and Yahr stages MDS-Unified Parkinson’s Disease Rating Scale Other resources Discussion

4. Outline Overview of scale usage in Parkinson’s disease Review of two primary scales Hoehn and Yahr stages MDS-Unified Parkinson’s Disease Rating Scale Other resources Discussion

5. 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

6. Usual primary measures Motor Tremor Bradykinesia Rigidity Gait and balance Non-motor Depression Cognition

7. 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

9. 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

10. 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

11. Patient examples Extracted from Common Movement Disorders: Video educational program Harold L. Klawans, Christopher G. Goetz and Caroline M. Tanner Raven Press 1990.

12. Hoehn and Yahr Stages

13. 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.

15. 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

16. 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)

17. 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

18. 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

19. 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

20. 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.

Rest Tremor Consistency

21. 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

22. 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

23. 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

24. Video demonstration

25. Apathy

26. 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

27. Questionnaire

28. 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
