Exploring physiotherapy for Parkinson s disease: A Delphi survey

1. Exploring physiotherapy for Parkinson�s disease: A Delphi survey Presented by: Charmaine Meek, Research Physiotherapist Primary Care Clinical Sciences, University of Birmingham On behalf of the PD REHAB study group

2. Background: The need for a clear definition of physiotherapy Physiotherapy is viewed as essential within the management of people with Parkinson�s disease (PD). Its inclusion in the care of PD patients is supported by national guidelines, and there is a growing body of evidence suggesting its efficacy. A recent survey by Parkinson�s UK (formally the Parkinson�s Disease Society; PDS, 2008), noted an increase in the utilisation of physiotherapy by patients in the UK, with 54% of respondents accessing physiotherapy. However, our understanding of what physiotherapy should entail for this population is limited.

3. Background: The need for a clear definition of physiotherapy Current evidence exploring the definition, structure and content of physiotherapy practice for PD: Dutch surveys (Keus et al, 2004; Nijkrake et al, 2009) PD: Physiotherapy Evaluation Project (Plant et al, 2000) Further evidence is now required following the publication of a number of large efficacy trials, as UK physiotherapy practice may have changed. A survey of physiotherapy practice within the UK would provide a framework to: Inform the physiotherapy intervention delivered within the PD REHAB trial. Promote equality in clinical practice

4. Aims of the Delphi survey To conduct a survey to explore best practice physiotherapy for people with PD, uncovering what UK physiotherapists identify as: The reasons for providing physiotherapy The core areas of physiotherapy Perceived effective treatment techniques and modalities The outcomes that should be measured when managing PD To obtain information on the current structure and delivery of UK physiotherapy services

5. Methods of the Delphi survey Design A two round modified Delphi survey with additional closed-question questionnaire Participants Clinical physiotherapists or research physiotherapists with an interest/ expertise in the management of people with PD Setting Conducted from the University of Birmingham and disseminated to members of the Delphi panel via email

6. Design of the Delphi survey

7. Results: Delphi and questionnaire response Out of a database of 107 therapists: 76 (71%) responded to the first round of the Delphi 61 (80%) responded to the second round of the Delphi 70 participants completed the additional closed question questionnaire

8. Findings from the optional questionnaire

9. Respondent characteristics Mean number of years qualified: 17.6 years (range 3-40) Number of PD patients treated in the past year: median 25 (range 3-250) 54% working full time 85% identified themselves as having a specific interest in PD 60% had received post-graduate training applicable to PD management 89% of those who hadn�t received post-graduate training would like to

10. Structure and delivery of services Referral Majority of referrals made to physiotherapy services by the PD nurse specialist 45% of services allowed initial patient/ carer self referral 78% of services allowed patients to re-access physiotherapy through self referral Majority of referrals reported to occur in the maintenance and complex phases of the disease Setting Therapy predominantly delivered in the patient�s home or outpatient setting

11. Structure and delivery of services Structure 75% delivered physiotherapy within a multidisciplinary team format Only 25% delivered care co-ordinated by a key worker (most often a PD nurse specialist) 52% of therapists delivered physiotherapy combining individual and group sessions 43% of therapists delivered physiotherapy through individual sessions only Course of physiotherapy Median of 6 sessions per course of physiotherapy (range 1-20) Median of 60 minutes for the initial assessment (range 30-90) Median of 45 minutes for follow up sessions (range 20-75) Course of therapy delivered over a median of 8 weeks (range 1-39)

13. Delphi survey: Reasons for physiotherapy

14. Delphi survey: Core areas of physiotherapy Consensus No Consensus

15. Delphi survey: Treatment within physiotherapy

16. Perceived effective treatment techniques: Gait Consensus External cueing techniques (visual/ auditory/ sensory/ verbal prompts) Cognitive movement strategies Lower limb strengthening exercises Joint mobility exercises Functional walking practice (obstacles, turning etc) Walking practice utilising patient�s environment Education and practice using walking aids Mental rehearsal Compensatory strategies

17. Perceived effective treatment techniques: Balance Consensus Multifaceted, progressive exercise programmes Rehabilitation based in a variety of settings (indoor and outdoor) Teaching and practising how to get on and off the floor Axial control and coordination exercises Secondary effects of gait rehabilitation (cueing and cognitive strategies)

18. Perceived effective treatment techniques: Transfers Consensus for all statements Cognitive movement strategies External cueing techniques Education and practice with equipment Home environment assessment Rehabilitation optimised through task specificity Education and training of carers

19. Perceived effective treatment techniques: Physical conditioning Consensus Resistance exercises Joint mobility/ flexibility exercises Cardiorespiratory training Posture rehabilitation to support cardiorespiratory capacity Recreational activity/ self-management Referral to leisure facilities Functional, task specific training Education

20. Perceived effective treatment techniques: Posture Consensus Axial control and coordination exercises Strengthening of the core muscles Verbal and visual feedback Education Passive and positional stretching

21. Perceived effective treatment techniques: Upper limb Consensus Resistance and range of movement exercises Upper limb coordination exercises

22. Provision of additional treatment and complementary therapies Consensus: Breathing exercises for management of respiratory complications No consensus: Manual chest physiotherapy for respiratory complications, management of pain (acupuncture, TENS, massage, prolonged stretching) No consensus: Inclusion of complementary therapies (Alexander technique, Pilates, Tai Chi, Yoga)

23. Outcome measurement

24. Outcome measurement Outcome measurement should be: Objective in nature, either with or without additional subjective measures Recorded pre and post treatment to monitor change Recorded over an extended period of time in order to monitor disease progression The findings of outcome measurement should be used to influence future practice

25. Top outcome measures used in practice Berg balance scale (43*) Lindop PD assessment (26*) 10 metre walk (25*) TUG (16*) TUAG (15*) Tinnetti (13*) Functional reach (11*) Elderly mobility scale (10*) UPDRS/ 6 min walk test/ 360 degree turn/ tragus to wall in standing (7*) 180 degree turn (6*) * : number of respondents listing outcome out of 65

26. Conclusions Current services Responding therapists were highly experienced in both years qualified and number of patients seen. Physiotherapy is predominantly delivered in the patient�s home or an outpatient setting, often combining both group and individual sessions. The physiotherapist often acts as part of a MDT. The PD nurse specialist plays a central role in referral to physiotherapy services, although the possibility of patient/ carer self referral is becoming more prominent in practice. Despite support for physiotherapy in all stages of PD, the majority of referrals are still only made in the maintenance and complex phases The dose of therapy delivered is comparable to that proposed following the PD: physiotherapy evaluation project (Plant et al, 2000) and current occupational therapy practice as reported by Deane et al (2003).

27. Conclusions Delphi survey of perceived best practice There are high levels of consensus regarding the reasons for delivering physiotherapy, and the core areas focused upon in practice. These reasons and core areas are wide ranging, covering all levels of the ICF model Treatment is perceived to be best when task and patient specific. There are high levels of consensus for the perceived effective treatment techniques for gait and balance, perhaps due to the increased levels of high quality evidence in these areas. Despite being recognised as core areas, there is less consensus around the treatment of posture and the upper limb. Outcome measurement predominantly focuses on the activity level of the ICF model, as illustrated by the outcome measures used most often in practice. The reported use of outcome measures in practice was much higher than previously reported in the literature.
