SCI rehab mgmt of impairments and exercise Flashcards
Goals of rehab
Optimise function, independence and participation in society
Within context of the individual’s level and severity of injury, and associated predicted outcomes:
Paraplegia – independent at all levels Tetraplegia :
High tetraplegia C1-4, most C5 – dependence
Low tetraplegia C6 or below: assistance of 1 to independent
(Not so clear cut for incomplete injuries)
Consider ICF personal and environmental factors
managment of impairments
Respiratory function Strength training Contracture management Pain management Cardiovascular fitness training Spasticity management
respiratory management
Major cause of morbidity and mortality in SCI
Common respiratory complications
Hypoventilation Atelectasis Secretion retention Pneumonia
Ventilation / perfusion mismatch
Tetraplegia more vulnerable than paraplegia
Below what level can we deem respiratory function to be normal?
innervation
Levels of innervation for the sternocleidomastoid, diaphragm, scalene,
pectoralis, intercostal and abdominal muscles
Cranial Nerve XI
Sternocleidomastoid
C3-C5
Diaphragm
C3-C8
Scalene
abdominals intercostals - all the way down to T12
may have some impairment
not as productive a cough
C5-T1
Pectoralis
T1-T11
Intercostals
T6-T12
Abdominals
respiratory complications
Respiratory muscle fatigue or paralysis Prolonged bed rest Pain and sedation Aspiration Paralytic ileus Associated respiratory injuries
assessment of respiratory function
NOT ON EXAM
NOT ON EXAM Level of distress / anxiety Shortness of breath Alertness Pattern of breathing Effectiveness of cough Respiratory rate Breath sounds Body temperature Heart rate
Need for additional oxygen Volume of secretions Tenacity of secretions Vital capacity FEV1 ABGs Oxygen saturation End-tidal CO2 X-ray changes
respiratory treatment options
Exercise training of the upper and lower limbs Inspiratory muscle training Pharmacological interventions Assistive devices Secretion removal Electrical stimulation
exercise training for respiratory function: UL and LL
Exercise training might improve resting and exercising respiratory function in
people with SCI
FES-induced cycle ergometry increased peak O2 uptake, CO2 production and
pulmonary ventilation
To achieve respiratory benefit, training intensity must be relatively high (70- 80% of maximum heart rate) and performed 3 times per week for at least 6 weeks
inspiratory muscle training
Improves respiratory muscle strength and endurance in people with SCI
Might decrease dyspnoea and respiratory infections in some
assistive devices
Mechanical ventilation
Ventilator weaning should be considered through a progressive protocol where appropriate
Resistance and endurance training should be considered in patients who are candidates for ventilator weaning
Other methods of ventilation
Non-invasive ventilation
Phrenic nerve pacing
Intermittent Positive Pressure Breathing
Little evidence for its effect
Abdominal binder
Can be used to achieve immediate improvements in respiratory function but long term effects have not been established (Wadsworth et al., 2012)
Tracheostomy decannulation
Should be considered where possible
Indications and criteria in SCI have not been established
secretion removal
Common practice but limited evidence
Manual assisted cough
Mechanical insufflation / exsufflation
cough assist- compression force applied to aid expulsion of secretions - not much evidence
mechanical insufflation or exsufflation is better
electrical stimulation
Phrenic nerve pacing (PNP) for diaphgram stimulation
Higher survival rate, better power wheelchair management, phonation success and patient satisfaction compared to mechanical ventilation
Can be used as long-term alternative to
mechanical ventilation
Abdominal neuromuscular stimulation
Can improve cough pressure
strength training
Performance of motor tasks can be limited by the strength of
Completely paralysed muscles
Partially paralysed muscles
Non-paralysed / neurally intact muscles There are different considerations for each (treatment and evidence)
Consider power and endurance functions related to the task
Principles of specificity and load
Importance of goal setting
assessment of strength
Manual muscle test Individual muscles Groups of muscles
Oxford scale / MRC Scale (part of AIS assessment)
One repetition maximum (1RM) Relevant for exercise prescription
Hand-held dynamometers Standardisation required
strength training of neurally intact muscles
Progressive resistance training of non- paralysed muscles improves voluntary strength and quality of life in people with SCI
Follow the principles of strengthening as you
would for any healthy muscle
Key aspects: resistance, reps and sets, and progression
60-80% 1RM, about 8-12 reps (Rhea et al
2003)
Specificity of training: Consider functional tasks facing the person with SCI (for example, getting up from the floor to the wheelchair)
