Flexibility/ROM Flashcards
Flexibility vs. ROM
- Flexibility
~ Musculotendinous unit’s ability to
elongate with application of force - ROM
~ Amount of mobility of a joint
~ Determined by soft tissues and bony
structures - ROM may be limited due to a lack of
flexibility
Flexibility/ROM Importance
- Allows for proper quantity and quality of
movement
~ Decreases compensations in the
Kinetic Chain
> Allows all links to contribute to the
activity
~ Allows for greater “forgiveness” in
prevention of injury
Flexibility/ROM Limiting Factors
- Muscle spasm
~ Natural reaction to pain/injury
~ Part of the pain/spasm/stasis cycle
~ Body’s way of bracing the area to
protect the injured structures - Scar tissue
~ Both positive and negative
~ Scar tissue is less flexible than other
tissue = limiting
~ Can be modified with stress to avoid
limitation
~ Adhesion
> Scar tissue formation between
layers of soft tissue
~ Joint Contracture
> Loss of ROM typically due to scar
tissue formation or lack of
flexibility in joint capsule - Neural Factors
~ Nervous system is continuous
> Impingement at any site can cause
tension throughout the system - Tension
~ Nervous system is enclosed in Fascia
that can be injured or tightened with
immobilization - Effects of Immobilization
Flexibility/ROM Limiting Factors: Effects of Immobilization
- Connective Tissues
~ Tissue Composition
> Collagen
> Elastin
> Fibroblasts
> Ground Substance
• Organic gel that lubricates and
maintains space between fibers
~ Immobilization decreases the amount
of Ground Substance decreasing
space and lubrication
> CT becomes tight - Muscle
~ Fibers and bundles are wrapped in
CT that can tighten
> Due to decreased Ground
Substance
~ Muscle will adapt to immobilized
position by changing its resting
length
Techniques to Increase Flexibility/ROM
- ROM Exercise
~ PROM
> Causes scar tissue to be laid down
in a more organized way
> Moves synovial fluid to nourish
cartilage
> No output
> Must use care to not disrupt
healing~ Once done, AROM > Causes scar tissue to be laid down in an even more organized way > Moves synovial fluid to nourish cartilage > Output occurs > Must use care to not disrupt healing ~ Once done, RROM and or Functional Activity
Stretching Techniques: Static
- Lengthening or decreasing tone of a
muscle by placing it in a position of
stretch (tension) and holding it for an
extended amount of time
~ Holding it activates the GTO causing
the muscle to relax
~ Causes habituation of the MS,
decreasing their activation due to
repeated or prolonged stimulation
~ Duration of Hold Time: 15-30 seconds
is optimal - Can’t be done too early, it can disrupt
healing if a muscle strain is present
Stretching Techniques: Balistic
- Repetitive bouncing motions
~ Antagonist is inhibited by contraction
of the agonist allowing for greater
degree of movement
> Reciprocal Inhibition (RS)
> Retraining/Neurological Effects
• Closely mimics the way muscles
function during activity: Muscles
are eccentrically loaded before
contracting concentrically during
functional activity - does not
contribute to lengthening, but
prepares muscles to work
efficiently
Stretching Techniques: Proprioceptive Neuromuscular Facilitation (PNF)
- Techniques use the GTO, MS, and RS to
increase flexibility
PNF Contract Relax Technique: GTO
- Limb is passively moved to a position
where resistance is sensed - Pt. is instructed to perform an isotonic
contraction against resistance for
5-10 seconds - The muscle being treated is relaxed and
the limb is passively moved to a new
point of resistance - This process is repeated a total of 3 times
PNF Hold Relax Technique: GTO
- Limb is passively moved to a position
where resistance is sensed - Pt. is instructed to perform an isometric
contraction (GTO) against resistance for
5-10 seconds - The muscle being treated is relaxed and
the limb is passively moved to a new
point of resistance - This process is repeated a total of 3 times
PNF Slow Reversal Hold Relax Technique: RI & GTO
- Limb is actively moved to a position
where resistance is sensed - Pt. is instructed to perform an isometric
contraction (GTO) against resistance for
5-10 seconds - The muscle being treated is relaxed and
the limb is actively (RI) moved to a new
point of resistance - This process is repeated a total of 3 times
Active Isolated Stretching: RI
- Limb is moved to the end ROM by one
muscle group and a 2 second stretch is
applied with external assistance - Increases flexibility by stretching CT and
lengthening it to a new length
Joint Mobilization
- Used when limitation for Flexibility/ROM
is associated with the CT of the joint
~ Joint capsule
~ Ligaments
~ Caused by tight CT due to inactivity
and or scar tissue - Can also be used to reduce pain
Joint Mobilization Characteristics
- Passive
- Technique may be oscillatory or a
sustained stretch - Techniques typically uses accessory
movements to enhance physiological
movement
~ Physiological
> Movements the pt. can do
voluntarily (In/Ex rotation of
shoulder)
~ Accessory
> Movements that are necessary for
normal ROM but can’t be
performed by pt.
> Occurs during physiological
movements (Ex rotation and
translation of humeral head
during Ex rotation of shoulder)
Joint Shapes
- Ovoid
~ One surface is convex and the other is
concave
~ Tibiofemoral Joint - Sellar/Saddle
~ One surface is concave in one
direction and convex in the other with
the other bone being convex and
concave, respectively
~ Articulation between thumb and
trapezium carpal bone
Joint Mobilization: Accessory Motions
- Rolling
~ New points of one surface meet new
points on the opposing surface
~ Never alone - Sliding
~ Same point on one surface comes into
contact with new points on the
opposing surface
~ Gets taken of advantage of during
Joint Mobilization
~ Never alone - Spinning
~ Rotation around a stationary axis
~ Same point on the moving surface
creates an arc on the opposing
surface
~ Never alone - Compression and Distraction
Concave - Convex Rule: Concave on Convex Movement
- Key to knowing in which direction to
mobilize a joint - Concave surface moving on convex
surface moves in in the same direction as
the moving bone
~ Slide occurs in the same direction as
the physiological movement
> Posterior rolling = posterior
sliding
> Ex: Open chain knee extension to
flexion
Concave - Convex Rule: Convex on Concave Movement
- Convex surface moving on concave
surface - Convex surface moves in the different
direction as the moving bone - Slide occurs in the opposite direction as
the physiological movement
~ Inferior sliding = superior rolling
~ Ex: shoulder abduction/adduction
How do you increase flexion or extension in the knee?
- Flexion
~ Mobilize the Tibia posterior - Extension
~ Mobilize the Tibia anteriorly
When would you use Joint Mobilization?
- Pain is preset
- Joint Capsule Limitation
~ Capsular Pattern Demonstrated
> Specific and predictable
limitations in PROM
> Due to tight joint capsule
~ Abnormal “Capsular” Joint End Feel
> Similar to tissue stretch, but
occurs earlier in the ROM and has
a firmer feeling
> Due to tight joint capsule - If AROM and PROM are both limited =
Capsular pattern or abnormal capsular
joint end feel
Dosages of Joint Mobilization: Graded Oscillation Techniques (Maitland) and its Grades
- Dosage: amount of joint translation into
tight tissues> Grade 1 - Small amplitude, rhythmic oscillations at the beginning of the range of joint play > Grade 2 - Large amplitude, rhythmic oscillations within the range of joint play > Grade 3 - Large amplitude, rhythmic oscillations stressed into tissue resistance > Grade 4 - Small amplitude, rhythmic oscillations stressed into tissue resistance > Grade 5 - Small amplitude with stress past resistance. Manipulation
- Quick stretch and release
- The higher the grade, the higher the
tension - Mobilization means turning liquid in the
joint into gas = popping sounds - Grades 1 and 2 are for pain management
and not ROM - Joint Mobilization is also good at sending
more sensory impulses to brain
Dosages of Joint Mobilization: Sustained Translatory Techniques and its Grades
- Grade 1 - Small amplitude distraction
without stress to capsule - Grade 2 - Distraction with or without a
glide to tighten the capsule - Grade 3 - Distraction and glide with an
amplitude large enough to place a
stretch on the capsule - Holds stretch
- Lower grades can be used to see pt.
tolerance
Joint Mobilization Procedures: Position
- Pt. and joint in a position of relaxation
- Begin with joint in a resting position and
not closed packed - Closed packed (tight/full extension)
~ Position in which both the articular
surfaces are in maximum congruency
resulting in the greatest mechanical
stability for that joint
~ Most ligaments and capsules
surrounding the joint are taut
~ Doesn’t allow for movement
ultimately not allowing for proper
joint mobilization
Joint Mobilization Procedures: Stabilization and Treatment Force
- Stabilization
~ Stabilize the proximal bone
~ Belt, hands, Pad, or Table - Treatment force
~ Apply force as close to the joint line as
possible
~ Use large of a contact surface as
possible
> Don’t use thumbs, use whole
palm of hand
