- Passive accessory glides (and end feel)
- Stability tests
What are two steps in treatment of hypermobility?
- Mobilize hypo mobile tissues or joints
2. Activate and “strengthen” to stabilize the hypermobile/unstable area
What are two purposes of bracing and taping?
- Restrictive
2. Proprioceptive
_________ = decreased mobility or restricted motion
hypomobility
What is one of the largest factors contributing to hypomobility?
prolonged immobilization
___________ = adaptive shortening of the muscle-tendon and other soft tissues that cross or surround a joint resulting in significant resistance to passive or active stretch and limitation of ROM
contracture
Contracture is described in terms of the action of the ________ muscle.
shortened
What are the 5 types of contracture?
- Myostatic
- Pseudomyostatic
- Arthrogenic
- Periarticular
- Fibrotic
________ = intrinsic property of body tissues, including muscle and connective tissues, that determines the ROM achievable without injury at a joint
flexibility
________ ________ = stiffness in one muscle group or joint will cause compensatory movement at adjoining joints that are controlled by muscles and soft tissues that exhibit less stiffness.
relative flexibility
What are 5 areas that immobilization may effect?
- Muscle
- Tendon
- Ligament
- Articular cartilage
- Bone
What 3 things decrease in muscles post immobilization,, leading to muscle atrophy and weakness?
- muscle fibre cross-sectional area
- # of myofibrils in a muscle fibre
- Motor unit recruitment
If immobilized in a shortened position, the length tension shift curves ________.
left
If immobilized in a lengthened position, the length tension curves shifts _______.
right
_________ weakness = the weakness that develops from a muscle remaining in an elongated position
stretch
________ shortening = the tightness that developed from a muscle remaining in a shortened position
adaptive
Stretch weakness results in relative weakness in ____ and ______ ROM.
mid; inner
Adaptive shortening leads to relative strength in ______ ROM.
inner
Post-Immobilization, a tendon has decreased ________ strength.
tensile
What 3 things occur to ligaments post immobilization?
