What is soft tissue deformation
Change in shape of soft tissue through external or internal forces
Examples of external forces used to create soft tissue deformations
•compressive forces/ compression
•tensile forces/ tension
•twisting forces/ torsion
•shearing forces
Examples of internal soft tissue deformation
•gravity
•poor body mechanics
What happens when you have internal soft tissue deformation
Internal forces may result in muscle tension from the force of gravity pulling on the tissues
Poor body mechanics may cause soft tissue to tighten, shorten, weaken or lengthen resulting in possible nerve compression, pain or dysfunction
What happens when you apply external forces to deform soft tissue
External forces may be applied therapeutically to positively affect soft tissue structures
What soft tissues are affected by applying therapeutic forces
•skin
•subcutaneous fascia
•deep fascia
•myofascia
•muscle
•as well as nerves, nerve endings, blood vessels, and lymph associated with those soft tissues
What can therapist use to apply compression forces?
Fingers
Palms
Entire hand
Fist
Forearm
How can compression be used as an assessment tool?
May be used as an assessment tool to examine…
Repetivity
Resistance
Tension
Tissue density
Or mobility of tissue
Compression forces can be used to?
Enhance local circulation
May sedate/stimulate tissue
Override nerve impulses
Separate fascia
Initial effect of compression forces?
Press/reduce space between structures
Secondary effect of compression forces?
Rebound/opening/expanding tissue
Can passively shorten or compress a muscle
What is Tensile force/tension
Opposite of compression used to elongate tissue by pulling layers of tissue apart from each other
How to apply tension forces?
Engaging tissue with two hand + moving hands away from each other
Using little to no lubricant
This can be applied by..
Tractioning
Pulling
Stretching
Or lengthening the targeted tissues
What happens to the tissues and muscles when therapist applies tension forces?
Elongate or stretch tissue between hands
Can be used to separate or stretch muscle fibers or to enhance the elasticity of facia and other soft tissue
Tension forces helps?
Elongate shortened tissues
Reduce adhesions
Improve ROM
Improves elasticity of fascia
What is muscle tension?
The result of increased motor nerve activity, causing the muscle to contract or increase its tone
Extreme or sudden tensile force on soft tissues?
•Is a common cause of injuries such as
•Ligament sprains
•Muscle strains
•Nerve traction injuries
What does Twisting forces/Torsion/torque do to the tissues? How?
Deforms tissues by shifting structures against each other
(Compressing and twisting one end of structure in one for while other end is help or compressed twisting in opposite direction)
Twisting forces/torsion or torque techniques include?
Kneading and wringing movements
Twisting/ torsion methods help?
Break up adhesive bonds between tissues
Enhance local circulation
Make muscle more pliable
What does Shearing forces do to tissue
Deforms tissue by shifting different structures agains each other
How to apply shearing forces?
Frictioning techniques
By using fingers pushed deeply and moving back/forth or circular movements
Shearing forces help?
•Generate heat
•Create therapeutic inflammation that warms the connective tissue, thus helping increase its pliability
•Helps reduce adhesions
Reorganize collagen and fiber alignment
What are the 7 common massage methods
• static
• gliding
• torsion
• shearing
• oscillating
• percussive
• joint movement
