  2. Learning Objectives At the completion of this presentation, the learner will be able to: • Describe the main principles of NDT • Describe early NDT vs. recent NDT • Describe the effectiveness of WSTT vs. NDT for improving gait • Describe how NDT compares to other conventional therapy approaches. • List common problems with reviews of NDT

  3. NDT Background • NDT approach began in the early 1940’s from the work of Mrs. Berta Bobath (Physical therapist) and pediatric neurologist Dr. Karel Bobath (Psychiatrist/Neurophysiologist). • Based on their experience of working with children with CP and adults with hemiplegia • Observations were based on the Reflex/Hierarchical model

  4. NDT and Adult Hemiplegia Main problems in patients with UMN lesions: • Abnormal coordination • Abnormal postural tone Thus, aims should be: • Introduction of more selective movement patterns in preparation for functional skills • Reduction of spasticity Bobath, 1990

  5. Early NDT Bobath originally believed in reflex inhibiting postures (RIPs) • Placed and held patients in RIPs to break up the abnormal postural and movement patterns. • Believed this would change the activity of the whole body due to the “normalization” of postural tone. • No spontaneous carry over into movement and function occurred. • Treatment was too static and was not continued in this way Bobath, 1990

  6. Revised NDT Theory: Dynamic “autoinhibition” by using reflex inhibiting movements • As patient moves, PT prevents the unwanted parts of the abnormal movement by using “key points of control” • Particularly proximal joints • PT should gradually withdraw control as the movement continues Bobath, 1990

  7. NDT Main Principles • It is impossible to superimpose normal movement patterns on abnormal ones, so abnormal patterns need to be inhibited • Movement is a sensory-motor experience: We do not learn a movement but the “sensation of a movement” • By moving the proximal part of the body it is possible to influence and change movements of the distal parts Bobath, 1990

  8. Evolution of NDT Principles • NDT in North America is currently based on an interactive complex systems model • Problems in tone, posture, balance, and movement are equally important in producing atypical synergies that interfere with functional activities. • NDT recognizes that it is essential to evaluate measurable changesin functions as well as changes in motor and body systems that support those functions. Neuro-Developmental Treatment Association, 2007

  9. Evolution of NDT Principles Original Core Concepts Still Applicable • Bobath’s therapeutic handling techniques make normal posture/movements more easy/likely to occur • Bobath’s focus on the interaction of impairments, function, and life participation (expanded to ICF) • Bobath’s focus on taking a “holistic” approach to treating patients Neuro-Developmental Treatment Association, 2007

  10. NDT in the Clinic Therapeutic handling allows the therapist to: • Feel the client’s response to changes in posture or movement • Fascilitate postural control and movement synergies that broaden the client’s options for selecting successful actions • Provide boundries for movements that distract from the goal • Inhibit or constrain those motor patterns that, if practiced, lead to secondary deformities, further disability, or decreased participation in society Howle , 2002

  11. Treadmill Training With Partial Body Weight Support Compared With Physiotherapy in Nonambulatory Hemiparetic Patients Heese, S. et al. Stroke. 1995;26:976-981 Weight Supported Treadmill Training vs. NDT

  12. Purpose • Compare the efficiency of PT based on NDT vs. WSTT in gait training for post stroke chronic hemi paretic patients. Heese et al. 1995

  13. Participants • 7 nonambulatory hemiparetic patients • 52 to 72 years old Heese et al. 1995

  14. Methods • A-B-A single case study design • 3 phases were administered to the participants • 1st phase= WSTT • 2nd phase= NDT • 3rd phase= WSTT Heese et al. 1995

  15. Results-Functional Ambulation Category Heese et al. 1995

  16. Results-Rivermead Motor Assessment Heese et al. 1995

  17. Results-gait velocity Heese et al. 1995

  18. Conclusion (Big Picture) • WSTT is superior to NDT because WSTT is… • Task oriented exercise • More independent • Higher dosage Heese et al. 1995

  19. Thaut, Leins et al. Rhythmic Auditory Stimulation Improves Gait More Than NDT/Bobath Training in Near-Ambulatory Patients Early Poststroke: A single-Blind, Randomized Trial. Neurorehabil Neural Repair 2007;21:455

  20. Subjects • 155 hemiparetic patients were randomly selected to (RAS group or NDT group). • Age: 69 ± 11 Thaut et al. 2007

  21. Methods • RAS - metronome and music tapes • NDT – Bobath principles • Major gait parameters measured: velocity, stride length, cadence, and swing symmetry. Heese et al. 1995

  22. Results Heese et al. 1995

  23. Conclusion (Big Picture) • According to this study RAS is superior to NDT because… • RAS gives the pt. an external cue to regulate parameters of gait. • It only works when its on. When off only a few minutes will transfer. Heese et al. 1995

  24. Paci, M. PHYSIOTHERAPY BASED ON THE BOBATH CONCEPT FOR ADULTS WITH POST-STROKE HEMIPLEGIA: A REVIEW OF EFFECTIVENESS STUDIES. J Rehabil Med 2003; 35: 2–7 • Systematic Review of 15 trials out of 726 • 6 RCTs, 6 CTs, 3 Case Series • No level 1 studies due to small sample size or weak evidence from P-value • Age range 15-95 years “NDT is the most widely used approach in the rehabilitation of hemiparetic subjects in Europe, and it is well known and frequently used in many countries, including the USA, Canada, Japan, Australia and Israel” Purpose: • Is there evidence that NDT is effective? • Is NDT more effective than other treatments for adults with hemiplegia?

  25. NDT Vs. EMG Feedback • No difference found in all outcome measures Upper Limb • EMG activity • Upper Extremity Function Test • Finger Oscillation Test • Health Belief Survey • Mood and Affect Tests Basmajian et al, 2003 Lower Limb • EMG activity • ROM • Gait analysis Mulder et al., 1986

  26. NDT Vs. Traditional Functional RetrainingGeneral Rx • NDT group improved more on Barthel Index than TFR • No significant difference in all measures • Functional Independence Measure (FIM) • Box & Block Test • Nine-hole Peg Test Salter et al., Gelber et al., Lewis, 2003

  27. NDT vs. BrunnstromGeneral Rx • No significant difference in all outcome measures • Action Reach Arm Test • Barthel Index • Gait speed Wagenaar et al., 2003

  28. NDT Vs. Motor Relearning ProgrammeGeneral Rx • MRP group improved more in: • Barthel Index • Motor Assessment Scale • Sodring Motor Evaluation Scale • No difference found in • Nottingham Health Profile Langhammer et al., 2003

  29. NDT Vs. Forced UseUpper Limb • Forced Use group had more improvements than NDT in Action Reach Arm Test (dexterity) • No difference in all other outcome measures • Rehabilitation Activities Profile • Fugl-Meyer • Motor Activity Log Van der Lee et al., 2003

  30. Conclusion • No evidence supporting NDT as the optimal type of treatment. • Important to note: • So even though NDT may NOT be superior, it does positively effect recovery • There was a significant improvement in most of the measured parameters for the NDT groups, but the improvements weren’t significantly different than other treatments Paci, 2003

  31. Hiraoka, K. Rehabilitation Effort to Improve Upper Extremity Function in Post-Stroke Patients: A Meta-Analysis. J Phys Ther Sci. 2001(13), 5-9. • Studies ranged between 1966 - 1999 14 trials reviewed • All RCTs Interval Since Stroke • 0 days to 8 years Length of Treatment • 2 to 50 weeks Sample Size • 20 to 282 people

  32. Methods • Interventions Assessed • NDT vs. Conventional PT • Conventional PT vs. No Rx • EMG biofeedback vs. Conventional PT • EMG biofeedback vs. No Rx • Upper extremity function assessed by: • Rivermead Motor Assessment Arm Scale, • Action Reach Arm Test, • Fugl-Meyer Assessment, • Upper Extremity Functional Test, • Frenchay Arm Test. Hiraoka, 2001

  33. Results • Used Cohen’s criteria to determine effect size - Large effect (significant difference) = ≥0.8 - Medium effect (difference) = 0.5 – 0.8 - Small effect (no difference) = 0.2 – 0.5 • Interventions Assessed • NDT vs. Conventional PT: effect size = (0.01) • Conventional PT vs. No Rx: effect size = 0.51 • EMG biofeedback vs. Conventional PT = 0.75 • EMG biofeedback vs. No Rx = 0.85

  34. Conclusion • The effects of NDT and conventional treatment are almost identical • EMG Feedback had a larger effect on improving UE function in post stroke patients than NDT or conventional PT Hiraoka, 2001

  35. Yelnik, A. et al. Rehabilitation of Balance After Stroke With Multisensorial Training: A Single-Blind Randomized Controlled Study.Neurorehabil Neural Repair 2008; 22: 468 Objective: Compare 2 physical rehabilitation approaches to restore balance after recent stroke: NDT vsMultisensorial Training Methods: 68 patients who were able to walk without human assistance 3 to 15 months post first stroke Received NDT or Mulitisensorial Rx for 20 sessions in 4 weeks Sample Size NDT = 35 patients Multisensorial = 33 patients

  36. Outcome Measures Standing balance • Berg Balance Scale Dynamic balance • Assessed during walking by percentage of double-limb stance time Daily Independence • Functional Independence Measurement (FIM) Quality of Life • Nottingham Health Profile Yelnik et al., 2008

  37. Assessment Differences between groups on Day 30 • No difference between groups Differences between groups on Day 90 • Both the NDT and Multisensorial approach showed significant improvements in all outcome measures compared to baseline measures, but the Multisensorial approach showed more improvement. • However, the differences between-groups were of no statistical significance Yelnik et al., 2008

  38. Conclusion • No significant differences between NDT and Multisensorial Training • No evidence that one approach is superior to the other Yelnik, A. et al

  39. Kollen, B.J. et al. The Effectiveness of the Bobath Concept in Stroke Rehabilibation: What is the Evidence? Stroke (Journal of the American Heart Association). 2009(40), e89-e97. • 16 trials reviewed • Sample size: 813 patients total (21-120 in individual studies) • Inclusion criteria: • Involvement of adult patients with a cerebrovascular accident • The effects of the Bobath Concept were compared with those of an alternative method • Randomized, controlled clinical trial (RCT) • Only English or Dutch publications were considered for inclusion.

  40. Inclusion Criteria (Cont.) • Rehab outcomes were measured in one or more of the following: • Sensorimotor function of the upper and/or lower extremity • Balance control • Mobility (The ability to (re)position the body by transfer or gait) • Dexterity (Reaching, grasping, fine hand use) • Activities of Daily living (ADLs) • Health-Related Quality of Life (HRQOL) • Cost effectiveness Boudewijn et al. 2009

  41. Results • There was no evidence of the superiority of NDT for sensorimotor control of the upper and lower limb, dexterity, mobility, ADLs, HRQOL, and cost-effectiveness • Only limited evidence was found to support the superiority of NDT for balance Boudewijn et al. 2009

  42. Common Problems with reviews of NDT • Little homogeneity between studies • Stage of stroke recovery • Treatment interval • Age of patients • Outcome measures • Treatment comparison • Failure to clarify exact methods used

  43. Why Do We Use NDT? • Personal Experience of the Therapist • Authority • Evidence Based Practice • NDT works, but not better or worse than other methods • If you are going to put your hands on a patient NDT is a good intervention to use

  44. HOWEVER, today there is good evidence to support other interventions: • CIMT • BWSTT • Task-Specific Training • Mental Imagery  WE NEED TO BE EDUCATORS IN THE CLINIC!

  45. Learning Objectives At the completion of this presentation, the learner will be able to: • Describe the main principles of NDT • Describe early NDT vs. recent NDT • Describe the effectiveness of WSTT vs. NDT for improving gait • Describe how NDT compares to other conventional therapy approaches. • List common problems with reviews of NDT
