The amount of motion that occurs when one segment of the body moves in relation to an adjacent segment

Range of Motion (ROM)


A movement produced entirely by an external force without voluntary muscle contraction by the subject

Passive Motion


AKA: Joint Play, the motion that occurs between the joint surfaces during normal physiological motion

Accessory Motion


Name a few causes of capsular patterns of restriction.

Effusion, Fibrosis, Inflammation


Tissue composed of the musculotendinous unit, which involves the muscle, the musculotendinous junction, the tendon, and the tendons interface with bone.

Contractile Tissue


A permanent shortening of a muscle producing deformity or distortion

Muscle Contracture


Intraarticular edema restricts motion in which pattern?

Capsular Pattern


List a few pathologies associated with spinal disc herniation.

blocked spinal motion, inflammation, hypertonic changes, decreased disc height and pain


What is the most common cause of adverse neural tension?

Restriction of nerve motion


List a common tool used to measure ROM.

Goniometers, Tape measures, Inclinometers


In terms of stretching, what is creep?

Transient lengthening or deformation with the application of a fixed load


In terms of stretching, what is stress relaxation?

A decrease in the amount of force required over time to hold a given length. (fig. 5-8, pg 120)


Plastic deformation

The elongation produced under loading that remains after the load is removed. Will have a permanent increase in length.


Passive stretching

The limb is held passively in a position in which the pt feels a mild stretch
EX: straddle sit (sitting on the ground, legs abducted to where the pt feels a mild stretch for 15-30 seconds)


Proprioceptive neuromuscular facilitation

Active muscle contraction followed by muscle relation in conjunction with passive stretch; greater skill involved.
Ex: leg kicks from supine, contracting the quadriceps to inhibit and stretch the hamstrings, an additional force is added at the end of movement with a rope or with a partner


Ballistic stretching

Active, quick, short-amplitude movements at the end of the pts available ROM.
• EX: Your 1980’s dance class warm ups
• EX: Bouncing in a passive stretch to take the stretch to the end of ROM


Benefits of CPM (continuous passive motion)

research varies but adding CPM to PT after TKA results in greater active knee flexion ROM and reduced length of stay and need for postoperative manipulation, additionally it accelerates healing and improves the orientation of collagen fibers and inhibits edema formation (pg 122)


How can modalities increase soft tissue extensibility?

Increase in tissue temperature = increase in soft tissue extensibility = decreasing the force required to increase tissue length and decrease risk of injury during stretching
Agents that increase superficial tissue temp should be used prior to stretching superficial tissues and the same for those that increase deep soft tissues


Controlling inflammation is a benefit because:

Cryotherapy and certain types of electrical currents control inflammation → help prevent the development of motion restrictions by limiting edema during the acute inflammatory stage = limiting the degree of immobilization
Controlling severity and duration of inflammation also limits the duration and extent of the proliferative response and may thus limit adhesion formation during tissue healing


Muscle length is tested in a 2-joint muscle by:

Muscle must first be elongated across one of the joints and then that joint must be held in that position while the muscle is elongated as far as possible across the other joint that it crosses (page 119)
