ACT 1 - Physio Flashcards
what is the foundation of exercise prescription?
What is the first step on clinical reasoning?
Subjective and Objective Ax
- Identify any pertinent red or yellow flags and individual safety concerns Consider the mechanism of injury
- Build rapport
- Exercise history
- Establish patient goals
- Identify impairments, Ax guide management/assess and re-assess
What is the second step of clinical reasoning?
STEP 2: Patient education and detailed planning of rehabilitation with periodisation methods (criteria are driven)
- Educationonpathology, prognosis, plan
- Adviceregardingsafeactivities
- Injuryspecificoutcomemeasures/milestones,
- Post-operativeorders
- Goalsetting: always align with patient goals (SMART)
- Collaborative process-Empower athlete/patient
Progression of rehab
Evidence and reasoning behind rehab
- management of many pain syndromes
- treatment of pain from tissue and psychological levels
- Mechanotransduction: the conversion of mechanical loads into cellular responses, and hence the structural change
- Adaptation response to exercise builds capacity which helps patient’s ability to perform task
Why do I prescribe exercise therapy?
- Prevent obesity and mitigate its risks
- Reduce development and improve management of diabetes
- Prevent and treat heart disease
- Treatment of hypertension
- Prevent osteoporosis and fractures
- Manage depression and anxiety
- Reduce risk of dementia and slow decline in cognitive impairment (Broadhouse et al., 2020)
- Manage frailty: Benefits of resistance training in physically frail elderly
- Recreational use
- Reduce risk of premature death
Components of a rehab program
Cardiovascular exercise
Any type of exercise, typically performed at moderate levels of intensity, for extended periods of time, that maintains an increased heart rate
- walking
- running
- swimming
- cycling
Muscle activation
Get the muscle working
Injury can inhibit muscle activation through:
- Pain
- Swelling
- Nerve injury
- Prolonged disuse
Muscle re-education
Get muscles working right
- Abnormal motor patterns may contribute to or be the cause of presenting injury
1. Palpate the muscle (patient and therapist)
2. Clear instruction (including demonstrations) and verbal cues
3. Verbal, visual (e.g. mirror), auditory and tactile feedback
4. Biofeedback
5. Muscle stimulation
Endurance exercise
Ability of muscle to perform repeated or sustained contractions (resist muscular fatigue), particularly when using sub-maximal resistance
- Targeted at muscle groups that are required to work at low-intensity for long periods
- Nearly all exercise programs will include endurance
- Level aligned to functional activity requirements
Hypertrophy
Increase in muscle size (CSA)
- After disuse or pain inhibited atrophy
- An important adaptation of resistance training because increase in muscle fibre size is important in improving force production
- High volume > low volume
- Working to failure (high volume) important if low load
- Balance is key when dealing with compromised tissue
- Isolated exercises often necessary early
- Periodization is key
Training load recomendation
Strength
Maximal amount of force exerted in a single attempt or Maximal force that muscle/muscle group can generate at a specified velocity
- Novice individuals = loads of 60-70%of1RMfor8-12repetition, Frequency 2 - 3 times per week, Volume 2 - 6 sets
- Experienced individuals = loads of 80-100%of1RMfor1-6repetitionsin a periodised manner, 3 - 4 times per week, Volume 2 - 6 sets
Power
Explosive power
- Ballistic (explosive) exercises: enable acceleration throughout the full range of motion
- Plyometric exercises: that involve the activation of the stretch-shortening cycle of movement and incorporate an eccentric component that is followed by a fast concentric component
- Light to moderate loading (30-60% of 1 RM) performed at an explosive velocity”
- Long rest periods
- Often restricted to late-stage rehab
3 types of muscle action
Isometric
- Muscle force generated without movement/change in length of muscle
Isotonic
- Concentric- Muscle gets shorter during active contraction. Total tension developed is sufficient to overcome an applied resistance
- Eccentric- Muscle gets longer during active contraction - More muscle tension developed
Isokinetic
- Muscle contracts while the joint moves at a constant speed throughout the range of motion
Mobilisation
Increase joint and soft tissue ROM and reduce resistance to movement
Used when:
- Deficit in ROM
- Excessive resistance to movement observed
Stretching
Increase soft tissue length and compliance
- • Tight/shortened muscles are observed
- • Warm up and cool down
- Static stretch
- stretch passively and held 15-30s, 2-4 repetitions
- Dynamic Stretching
- Involves continually moving a body apart through ROM Performed for 15-60s, or 10-20 repetitions
- Pre-contraction stretching:
- A passive stretch of the muscle, followed by isometric contraction of the muscle held 3-10s and repeated 3-7 times
Proprioception
Proprioception (position sense) is the body’s sense of position and movement, particularly limbs, which assists in the maintenance of balance and coordination
used on joint injury
Functional / sport specific
Ensure individual has met physical demands required to perform at the required functional level
