Lecture 2 - ROM flexibility and mobility Flashcards
When should a WU be done?
Before working out, not needed when the exercises are light
Components of WU (2)
General WU 5-10 min
Specific WU
Categories of components of injury prevention program (5)
Strength, balance, agility, flexibility, plyometrics
Basic definition of range of motion
Ability of a joint to move through full ROM in which it’s supposed to
What could affect ROM? (name examples)
- Swelling
- Pain
- Bony block
- Joint mouse
- Tear of labrum or menisci
- Tissue approximation
- Joints mechanics
- Strength
- Flexibility
Basic definition of flexibility
ROM a muscle can go through (specific to a muscle)
Basic definition of mobility
Motor control, strength, ROM and flexibility all working together (capacity to bring your body into certain positions using all these components)
Where does the injury usually occurs when talking about ROM?
Injury will occur in the specific range - the gap between active and passive - where they cannot control the motion properly
Importance of a warm-up (name examples)
- Increase blood flow (increase O2)
- Increase temperature
- Increase activation of muscles
- Increase neuromuscular connections
- Decrease risk of injury
- Increase elasticity (ROM)
- Decrease the viscosity in the joint
- Increase mindset
- Increase heart rate (increase BP, respiration rate)
T or F : any passive movements that the athletes want to do needs to be followed up by general and specific WU
TRUE
When should an injury prevention program be done?
Pre-season, in season, and off-season for minimum 2-3 times a week
What is a physiological movement/osteokinematics?
What we see
What is accessory motions/arthokinematics?
What is happening at the joint (ex: rolls, glides, etc.)
New points on one surface come into contact with new points on another surface
Accessory movements - ROLL
Movement where a constant point on one surface comes into contact with a new point on the other surface
Accessory movements - GLIDE
What is the male end
Convex
What is the female end
Concave
When the male end is moving roll and glide are ____
opposite
When the female end (concave) is moving roll and glide are ___
the SAME
Explanations for poor ROM (name examples)
Swelling
Pain (muscle guarding/spasm)
Decrease in arthrokinematics at the joints
Surgical or traumatic insults
Inactivity, immobilization
Neurological
Muscular diseases
2 indications for PROM
- in a region where there is acute, inflamed tissue
- when patient is unable to or is not supposed to actively move a segment of the body
Goals of PROM (name examples)
Maintain joint and connective tissue mobility
Minimize contractures
Maintain elasticity of muscle
Assist circulation and vascular dynamics
Enhance synovial movement for cartilage nutrition and diffusion of materials in the joint
Decrease or inhibit pain
Assist in healing process after injury or surgery
Help maintain patient’s awareness of movement
