  • 1. BY: EUSIVIA PASI MPT MANAGEMENT OF UPPER LIMB POST STROKE WITH RECENT ADVANCES
  • 2. DEFINITION OF STROKE Cerebral vascular accident has been defined as ‘a sudden, non-convulsive loss of neurologic function due to an ischemic or hemorrhagic intracranial vascular event’ (pubmed [medline], mesh database, 2005). The world health organization (who) definition of stroke is: “rapidly developing clinical signs of focal (or global) disturbance of cerebral function, with symptoms lasting 24 hours or longer or leading to death, with no apparent cause other than of vascular origin”
  • 3.  “Stroke or Brain Attack is the sudden loss of neurological function caused by an interruption of blood flow to the brain” by Susan B. O’Sullivan  “a focal (or at times global) neurological impairment of sudden onset lasting more than 24 hours (or leading to death) and of presumed vascular origin” by WHO Journal of the association of physicians of India, October 2013, Vol. 61  “a sudden loss of brain function resulting from an interference with blood supply to the brain” by National Institute of Neurologic Disorders and Stroke (NINDS), USA.

  • 9. TYPES OF STROKE Ischaemic stroke:  Blood supply to part of the brain is decreased, leading to dysfunction of the brain tissue in that area. 1) Thrombosis or embolism due to atherosclerosis of a large artery 2) Embolism of cardiac origin 3) Occlusion of a small blood vessel 4) Other determined and undetermined cause  Abuser of stimulant drugs such as cocaine and methamphetamine are at a high risk for ischemic strokes.
  • 10. Haemorrhagic stroke:  is the accumulation of blood anywhere within the skull vault. (1) Intra-axial hemorrhage (blood inside the brain)  is due to intraparenchymal hemorrhage or intraventricular hemorrhage (blood in the ventricular system) (2) Extra-axial hemorrhage (blood inside the skull but outside the brain).  epidural hematoma (bleeding between the dura mater and the skull),  subdural hematoma (in the subdural space) and  subarachnoid hemorrhage (between the arachnoid mater and pia mater).

  • 14. TITLE : LONG-TERM USE OF A STATIC HAND- WRIST ORTHOSIS IN CHRONIC STROKE PATIENTS: A PILOT STUDY AUTHOR : 1. Aukje Andringa 2. Ingrid van de Port and 3. Jan-WillemMeijer JOURNAL : Stroke Research and Treatment YEAR PUBLISHED : 31st January 2013
  • 15. OBJECTIVES:. Evaluating long-term use of static hand-wrist orthoses and experienced comfort in chronic stroke patients. METHODS 11 stroke patients who were advised to use a static orthosis for at least one year ago were included. Semistructured telephone interviews were conducted to explore the long-term use and experienced comfort with the orthosis. Data were analyzed using descriptive statistics. RESULTS After at least one year, seven patients still wore the orthosis for the prescribed hours per day. Two patients were unable to wear the orthosis 8 hours per day, due to poor comfort. Two patients stopped using the orthosis because of an increase in spasticity or pain.
  • 16. CONCLUSIONS. These pilot data suggest that a number of stroke patients cannot tolerate a static orthosis over a long-term period because of discomfort. Without appropriate treatment opportunities, these patients will remain at risk of developing a clenched fist and will experience problems with daily activities and hygiene maintenance.

  • 19. METHOD Seven chronic stroke survivors (5 female) aged 59.4 –79.6 years completed a 4 - 6 week upper limb training program using a table-supported computer input device (the Able Reach) to play bespoke computer games designed to encourage a large number of goal oriented arm movements. Over the course of the intervention, participants received between 9 (n = 4) and 16 (n = 3) hours of game play. On average, Fugl- Meyer scores increased by 4.9 over the course of the intervention, ranging up to 9 points. One participant gradually deteriorated throughout the trial. These results suggest that the Able Reach is a useful adjunct to regular physical therapy in a stroke population
  • 20. The Able Reach
  • 21. CONCLUSION Results provide evidence that the Able Reach in conjunction with bespoke computer games can significantly reduce upper limb impairment in chronic stroke survivors, is well tolerated and found to be motivating, useful and enjoyable. Future research include a larger clinical trial to confirm these results as well as automating the system so that it can be used without direct supervision.

  • 29. OBJECTIVES: To evaluate the effectiveness of non-immersive VR treatment for the restoration of the upper limb motor function and its impact on the activities of daily living capacities in post-stroke patients. METHODS: A pragmatic clinical trial of 376 subjects who had a motor arm subscore on the Italian version of the National Institutes of Health Stroke Scale (It-NIHSS) between 1 and 3 and without severe neuropsychological impairments interfering with recovery. Patients were allocated to two treatments groups, receiving combined VR and upper limb conventional (ULC) therapy or ULC therapy alone. The treatment programs consisted of 2 hours of daily therapy, delivered 5 days per week, for 4 weeks.
  • 30. Outcome Measures:  Fugl-Meyer Upper Extremity (F-M UE) and  Functional Independence Measure (FIM) scales. Study design: Cohort study
  • 31. Group 1 • Virtual Rehabilitation • Upper limb conventional Therapy Group 2 • Only Upper limb Conventional Therapy
  • 32. For 4 weeks For 5 days/ week 2 hours
  • 33. Results: The improvement obtained with VR rehabilitation was significantly greater than that achieved with ULC therapy alone. With F-M UE was 2.5 ± 0.5 (P < 0.001) and FIM scores 3.2 ± 1.2 (P = 0.007) respectively. Conclusions: VR rehabilitation in post-stroke patients seems more effective than conventional interventions in restoring upper limb motor impairments and motor related functional abilities. LOE:2b

  • 52. TITLE: EFFECTS OF ROBOT-ASSISTED THERAPY ON UPPER LIMB RECOVERY AFTER STROKE: A SYSTEMATIC REVIEW AUTHOR :Gert Kwakkel, Boudewijn J. Kollen, and Hermano I. Krebs JOURNAL :Neurorehabil Neural Repair. YEAR PUBLISHED: 2008 PURPOSE: To present a systematic review of studies that investigates the effects of robot-assisted therapy on motor and functional recovery in patients with stroke.
  • 53. Summary of Review—A database of articles published up to October 2006 was compiled using the following MEDLINE key words: cerebral vascular accident, cerebral vascular disorders, stroke, paresis, hemiplegia, upper extremity, arm and robot.  Studies that satisfied the following selection criteria were included: 1) patients were diagnosed with cerebral vascular accident 2) effects of robot-assisted therapy for the upper limb were investigated 3) the outcome was measured in terms of motor and/or functional recovery of the upper paretic limb  The study was a randomised clinical trial (RCT).
  • 54.  For each outcome measure, the estimated effect size (ES) and the summary effect size (SES) expressed in standard deviation units (SDU) were calculated for motor recovery and functional ability (ADL) using fixed and random effect models. Ten studies, involving 218 patients, were included in the synthesis.  Their methodological quality ranged from 4 to 8 on a (maximum) 10 point scale.  Meta-analysis showed a non-significant heterogeneous SES in terms of upper limb motor recovery.  Sensitivity analysis of studies involving only shoulder-elbow robotics subsequently demonstrated a significant homogeneous SES for motor recovery of the upper paretic limb.  No significant SES was observed for functional ability (ADL).
  • 55. CONCLUSION—  No overall significant effect in favour of robot-assisted therapy was found in the present meta-analysis.  Sensitivity analysis showed a significant improvement in upper limb motor function after stroke for upper arm robotics.  No significant improvement was found in ADL function.  The administered ADL scales in the reviewed studies fail to adequately reflect recovery of the paretic upper limb and valid instruments that measure outcome of dexterity of the paretic arm and hand are mostly absent in selected studies.  Future research on the effects of robot-assisted therapy to distinguish between upper and lower robotics arm training and concentrate on kinematical analysis to differentiate between genuine upper limb motor recovery and functional recovery due to compensation strategies by proximal control of the trunk and upper limb.
  • 56.  Robotics has been defined as: ‘The application of electronic, computerized control systems to mechanical devices designed to perform human functions’. (PubMed [Medline], MeSH database, 2005).
  • 57. TITLE : CONCURRENT NEUROMECHANICAL AND FUNCTIONAL GAINS FOLLOWING UPPER-EXTREMITY POWER TRAINING POST-STROKE AUTHOR : Carolynn Patten, Elizabeth G Condliffe, Christine A Dairaghi and Peter S Lum JOURNAL : Journal of NeuroEngineering and Rehabilitation 2013,
  • 58. PURPOSE :  Investigated how power training (i.e., high- intensity, dynamic resistance training) affects recovery of upper-extremity motor function post-stroke.  Hypothesized that power training, as a component of upper-extremity rehabilitation, would promote greater functional gains than functional task practice without deleterious consequences.
  • 59. METHOD:  Nineteen chronic hemiparetic individuals using a crossover design.  All participants received both functional task practice (FTP) and HYBRID (combined FTP and power training) in random order.  Blinded evaluations performed at baseline, following each intervention block and 6-months post-intervention included: 1. Wolf Motor Function Test (WMFT-FAS, Primary Outcome) 2. Upper-extremity Fugl-Meyer Motor Assessment, AshworthScale and 3. Functional Independence Measure.  Neuromechanical function was evaluated using isometric and dynamic joint torques and concurrent agonist EMG. Biceps stretch reflex responses were evaluated using passive elbow stretches ranging from 60 to 180º/s and determining: EMG onset position threshold, burst duration, burst intensity and passive torque at each speed.
  • 60.  RESULTS:  Primary outcome: Improvements in WMFT-FAS were significantly greater following HYBRID vs. FTP (p = .049), regardless of treatment order. These functional improvements were retained 6- months post-intervention (p = .03).  Secondary outcomes: A greater proportion of participants achieved minimally important differences (MID) following  HYBRID vs. FTP (p = .03). MIDs were retained 6-months post-intervention. Ashworth scores were unchanged (p > .05).  Increased maximal isometric joint torque, agonist EMG and peak power were significantly greater following HYBRID  vs. FTP (p < .05) and effects were retained 6-months post-intervention (p’s < .05). EMG position threshold and burst  duration were significantly reduced at fast speeds (≥120º/s) (p’s < 0.05) and passive torque was reducedpost-washout (p < .05) following HYBRID.
  • 61. CONCLUSIONS:  Functional and neuromechanical gains were greater following HYBRID vs. FPT. Improved stretch reflex modulation and increased neuromuscular activation indicate potent neural adaptations.  Importantly, no deleterious consequences, including exacerbation of spasticity or musculoskeletal complaints, were associated with HYBRID.  These results contribute to an evolving body of contemporary evidence regarding the efficacy of high-intensity training in neurorehabilitation and the physiological mechanisms that mediate neural recovery.
  • 62. TITLE: STRENGTH TRAINING IMPROVES UPPER- LIMB FUNCTION IN INDIVIDUALS WITH STROKE AUTH0R : Jocelyn E. Harris; Janice J. JOURNAL : American Heart Association YEAR PUBLISHED : 2009
  • 63. PURPOSE After stroke, maximal voluntary force is reduced in the arm and hand muscles, and upper-limb strength training is 1 intervention with the potential to improve function. METHODS  a meta-analysis of randomized controlled trials.  Electronic databases were searched from 1950 through April 2009.  Strength training articles were assessed according to outcomes: strength, upper-limb function, and activities of daily living.  The standardized mean difference (SMD) was calculated to estimate the pooled effect size with random-effect models.
  • 64. RESULTS From the 650 trials identified, 13 were included in this review, totaling 517 individuals. A positive outcome for  strength training was found for grip strength (SMD0.95, P0.04) and upper-limb function (SMD0.21, P0.03). No  treatment effect was found for strength training on measures of activities of daily living. A significant effect for strength  training on upper-limb function was found for studies including subjects with moderate (SMD0.45, P0.03) and mild  (SMD0.26, P0.01) upper-limb motor impairment. No trials reported adverse effects. CONCLUSIONS  There is evidence that strength training can improve upper- limb strength and function without increasing
