Stroke Rehabilitation: Let's Get Physical: Rehabilitation for Body, Mind, and Soul DR. RANI H. LINDBERG, M.D., FAAPMR Assistant Professor Residency Program Director BHRI Brain Injury Team, Medical Director
Goals and Objectives Describe the field of Physical Medicine and Rehabilitation Discuss qualifications for inpatient rehabilitation Review the timing and goals of Stroke Rehabilitation Review complications related to stroke and their effects on rehabilitation of a stroke patient
Physical Medicine and Rehabilitation: What is it? ABMS 1947 Physical Medicine (Thermal, E-stim, U/S) Rehabilitation (WWII) Physiatry / Physiatrist fizzy AT trist vs. fizz EYE uh trist Diagnosis, treatment, and rehabilitation of primarily neuromusculoskeletal and cardiopulmonary disorders, that may produce temporary or permanent impairment. PM&R
PM&R: What do they do? Focus: Maximize Function / Quality of life Physiatry: area of expertise is the functioning of the whole patient, as compared with focusing on a specific organ system or systems. Prescribe Medications and Therapy Team Approach (e.g., Physical / Occupational Therapy)
The Physiatric Approach Chief complaint Baseline level of function Current level of function What are the current barriers that are preventing the patient from reaching their desired level of function?
Who qualifies for inpatient rehabilitation?
Qualifying Diagnoses for Inpatient Rehab Stroke Spinal cord injury Congenital deformity Amputation Major multiple trauma Hip fracture Brain injury Neurological disorders (e.g., Multiple Sclerosis, Parkinson s) Burns 3 different arthritis conditions for which appropriate, aggressive, and sustained outpatient therapy has failed, and Joint replacement
Theory Behind Early Stroke Rehab Neuroplasticity: Modifications in neural networks are use dependent Need stimulation from: -Active rehabilitation -The environment www.omkararetreats.com
Timing for Inpatient Rehabilitation after Stroke? Studies show fewer days between onset of stroke and initiation of stroke rehabilitation is associated with improved functional outcome at discharge and shorter rehabilitation length of stay.
Stroke Rehabilitation: Goals Functional enhancement by maximizing each patient s: -Independence -Lifestyle -Dignity Focus on physical, behavioral, cognitive, social, vocational, adaptive, and re-educational points of view.

Special rehabilitation interventions and modalities NEUROREHABILITATION
Rehabilitation for the body LET S GET PHYSICAL
Motor Impairment and Recovery due to Stroke Up to 88% of stroke patients have hemiparesis Most recovery in 1 st three months with minor recovery after six months Typically, leg recovers before arm -Lower extremity pattern: flexor synergy à extensor synergy -Upper extremity pattern: flexor synergy à extensor synergy
Predictors of Motor Recovery Post-Stroke Severity of arm weakness 9% with good recovery of hand function Timing of motor return in hand If some return by 4 wks, 70% chance of full to good recovery Poor Prognostic indicators: 1) Severe proximal spasticity 2) Prolonged flaccidity period 3) Late return of proprioceptive response >9 days 4) Late return of proximal traction response>13 days
Rehabilitation Methods for Motor Deficits Traditional therapies consist of: 1. Positioning and ROM exercises 2. Mobilization 3. Compensatory techniques 4. Strengthening and endurance training For stroke rehabilitation, these exercises emphasize repetition of movements, importance of sensation to control movement, and developing basic movements and postures to improve motor control and coordination
Mobility Training Motor assessment should include strength, active and passive range of motion, tone, gross and fine motor coordination, balance, apraxia, and mobility. Motor function is addressed via rehabilitation efforts with strengthening, balance and gait training, orthoses, transcutaneous electrical nerve stimulation (TENS), robot-assisted movement therapy, constraint-induced movement therapy, and body-weightsupported treadmill training, and upper extremity interventions in order to improve activities of daily living. Functional electrical stimulation may help facilitate movement or compensate for lack of voluntary movement. Wells, George A., et al. "Ottawa Panel Evidence-Based Clinical Practice Guidelines for Post-Stroke Rehabilitation." Topics in Stroke Rehabilitation 2006; 13(2), 1-269. DOI: 10.1310/3TKX-7XEC-2DTG-XQKH
Technology in Rehabilitation Functional electrical stimulation: may help facilitate movement or compensate for lack of voluntary movement. Body-weight-supported (BWS) therapy: Robotics: A harness provides support of body weight over a treadmill or other surface, while a therapist can observe and correct any unwanted gait pattern. Robotic assisted gait devices are used for mobility training. Lightweight, motorized exoskeletons have become available very recently, but they are very expensive and slow. Studies are needed to show if they can be practically used as an augment to standard therapy.

Technology in Rehabilitation Virtual reality (VR): Virtual environments and objects provide the user with visual feedback and repetitive skills practice. A 2015 Cochrane review 17 found VR to be beneficial in improving upper limb function and ADL function as an adjunctive therapy or when compared with the same amount of standard therapy. Other 2015 review studies have shown efficacy of VR in improving neglect 18, balance and mobility 19.

Mirror Therapy This therapy involves placing a mirror in the mid-sagittal plane, allowing the patient to visualize the reflection of the non-paretic limb as if it were the paretic limb. Studies have generally shown statistically significant gains in motor function. The visual illusion of functional mobility in the hemiparetic limb results in stimulation of adaptive brain plasticity to counteract maladaptive neuro-plastic changes. www.recoverfromstroke.blogspot.com
Constraint -induced Movement Therapy CIMT is performed by restricting the unaffected limb for 90% of waking hours for 14 days, while intensively training the use of the affected arm. A number of studies have shown that CIMT induces a use-dependent increase in cortical reorganization of the areas of the brain controlling the more affected limb. 8,9 Studies have demonstrated significant improvements in motor and functional outcomes, although there have been mixed results. www.thestrokefoundation.com CIMT is shown to be effective in patients who have active wrist extension, active finger extension, 10 good cognition, limited spasticity, and preserved balance.

Cognitive Language Impairments Cognitive assessment should address arousal, attention, visual neglect, learning, memory, executive function, and problem solving.
Aphasia www.braininjury-explanation.com
Aphasia Impairment of the ability to utilize language due to brain injury Can also include impairment in reading, writing, and problem solving. Aphasiaà Longer rehabilitation length of stay Aphasiaà Decreased rehabilitation efficiency
Hemispatial Neglect Deficit in attention to and awareness of one side of space defined by the inability of a person to process stimuli on one side of the body or environment Three quarters of patients with acute stroke have signs of neglect Unawareness of deficit in 20% to 58% of patients Pts with neglect took longer to recover than other stroke patients with similar stroke pathology and impairment. Pts with neglect required more therapy input and have longer rehab LOS

Innovations in Cognitive Rehab Noninvasive Brain Stimulation (NIBS) - Transcranial magnetic and direct current stimulation: Mild magnetic/electric stimulation applied to the scalp. Theory: Neuromodulation of plasticity and cortical excitability. NIBS has been shown to improve motor function, gait, language (aphasia) and cognitive (neglect) deficits, and mood.

Outcomes and Return to Work
Outcomes The most reliable predictor of functional outcome during Rehab is the patient s functional ability on admission. An admission FIM score >60 is a good indicator.* Persistant urinary or fecal incontinence and the presence of a social support system is the key determinate in the ultimate discharge destination.** * Ween JE, et al. Neurology. 1996;46:388-392. * *Brandstater M. In DeLisa ed. Rehabiliatation Medicine 3 rd ed. 1998;1165-1189.
Predicting Outcomes Age Severity of stroke Prior stroke Persistant urinary incontinence Bowel incontinence Visuospatial deficits Unilateral hemineglect Coma at onset Poor cognitive function Multiple neruologic deficits Impaired sitting balance Poor social supports Limitations in ADLs Depression Severe aphasia Severe comorbid medical conditions Cerebral metabolic rate (PET scan)
Ambulation Potential Copenhagen Stroke study: 63% presented with impaired walking. Those who survived - 22% did not regain the ability to walk; 66% achieved independent walking, and 95% reached their maximum walking function at 11 months.* Most common lower extremity is an ankle-foot orthosis (AFO) both speed of gait and energy consumption can be improved using an AFO. ** *Jorgensen HS, et al. Stroke 1999;10(4):887-906. **Fowler PT, et al. J Orthop Res 1993;11:416-421.
Return to Work Negative factors that effect return to work: Low score on the Barthel Index Prolonged rehabilitation length of stay Aphasia Prior EtOH abuse Neuropsychological testing Functional Capacity Evaluation Return to work with restrictions www.guyanachronicle.com
How to prepare a patient for inpatient rehabilitation Initiate early rehab therapies: PT, OT, Speech, PM&R Prevent complications: -Early ROM, stretching, and splinting to prevent contractures -Shoulder slings and proper arm position in bed -High suspicion for dysphagia and close monitoring for aspiration -DVT prophylaxis -Monitor nutrition- PEG tube placement early if delayed recovery expected - Monitor for neglect and help patient compensate for it! - Bladder/bowel: timed voids if possible. Check PVRs!
