KNES 330 Study Guide
Flexibility Overview and Assessment
ROM
Range of motion
The measured beginning and terminal angles, as well as the total degrees of motion, traversed by a joint moved by
active muscles contracting or by passive movement
ROM is quantitative
Flexibility
The ability of a joint, or a series of joints, to move fluidly (smoothly and easily) through a full range of motion
(ROM) without pain or undue strain on the joint.
Flexibility is measured qualitatively
Specificity
Joint specific
Side of body specific
Action / sport specific
Speed specific
This is not the same as variability
Laxity
It is the looseness or freedom of movement in a joint that can be excessive or abnormal
It can be caused by:
o Chronic or acute injury (ACL tears, AC separation for example)
o Congenital conditions such as Ehlers-Danlos Syndrome and Marfan Syndrome
Laxity is objective
Instability
The state of being unstable, or lacking stability
The abnormal tendency of a joint to sublux or dislocate with normal activities and stresses
Also includes:
o Abnormal joint motion
o Pathological joint motion
o Reported dysfunction
o Inability to maintain control
Instability is subjective
Hyper-flexibility
Range of motion in excess of normal
Hypo-flexibility
Tight, limited range of motion
Relative Compensatory Flexibility
Taking on the path of least resistance
Imbalance
Difference in flexibility or strength between agonist and antagonist
Mobility versus stability stability is preferred over mobility

Types of Flexibility (So Brownie Does Flippin’ Perfect Acronyms)
Static
o Movement is held in one position for an extended period of time
o It can be self-propagated or assisted
Ballistic
o Bouncing, bobbing, out of control type motion at high velocity
o Movements may go beyond normal range of motion
Dynamic
o Full range of motion as normal or fast speeds
o Requires muscle activation to move the joint
Functional
o Flexibility that is necessary for the activity to be participated in
o Required for sport and includes strength
Passive
o The mobility around a joint that can be attained by moving the joint to an end feel
o No active contraction
Active
o Use of one’s muscle without assistance
o Mobility around a joint the supporting muscles can attain
Purpose of Assessment of Flexibility
Flexibility as a component of physical fitness / movement function
Sport teams / athletes to assess for injury risk and to address tightness and to enhance performance
Injury assessment and rehabilitation
Research studies
o Validity
o Reliability
Disease identification
o Hypermobility
Down Syndrome, Ehlers-Danlos, and Marfan Syndrome
o Hypomobility
Diabetes, fibromyalgia, growth
Flexibility Assessment:
Cureton’s Test
o Floor touch
o Trunk extension
o Trunk forward bend
Wells and Dillon
o Sit and reach
Measurements:
o Linear units linear distance between two body parts
o Angular units joint angles are measured in degrees
o Dimensionless
Flexibility Limitation and Flexitest
Structural Limitations
Bone
Muscle
Joint capsule
Tendons
Skin

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
