Friction is the counterforce that opposes motion or attempted motion
Friction is always parallel to the surface in contact and opposite in direction.friction
Friction must be considered when applying traction. You must overcome friction in order to achieve separation of joints.
When using a split table for lumbar traction friction is eliminated.Friction
A technique in which a joint is moved constantly in a mechanical splint to prevent stiffness and to increase the range of motion
Usually used post-operatively
Thought to prevent scar tissue from developing and decrease the problem of stiffnessContinuous passive motion (CPM)
Stiffness following surgery or injury to a joint develops as a progression of four stages : bleeding, edema, granulation tissue, and fibrosis
CPM properly applied during the first two stages of stiffness acts to pump blood and edema fluid away from the joint and periarticular tissues
This allows maintenance of normal periarticular soft tissue compliancePhysiological effects
Reduction in pain and discomfortTherapeutic effects
The use of CPM in conjunction with anticoagulation therapy may produce an intra-compartmental haematoma
The amount of time on the CPM machine ranges from 1 hour, three time a day to continuous for 24 hours. After surgery use is for 6 to 8 hours a day
Duration minimum for CPM is usually less than one week when a satisfactory range of motion is reachedApplication continued
A manual therapy technique comprising a continuum of skilled passive movements to the joint complex that are applied at varying speeds and amplitudes, with the intent to restore optimal motion, function, and/or to reduce pain
Uses a grading system for progression of forceMobilization therapy
A passive, high velocity, low amplitude thrust applied to a joint complex within its anatomical limit
Detailed knowledge of anatomy and biomechanics is required to perform this skill
Clinical practice and experience is essential in understanding joint play and the desired motion of each joint
Mobilization is not a skill to be preformed at the PT tech level unless advanced training has be takenapplication
How much distraction of the cervical spine is achieved with 25 pounds of traction?
What position causes the most intradiscal pressure? Which causes the least?
What are the general contraindications of traction?
When should intermittent vs. continuous traction be applied?
What amount of pull in needed in the lumbar spine?Comprehension Check
2-20mm of distraction of the cervical spine is achieved with 25 pounds of traction
Seated, bent forward with weights in the hands causes the most intradiscal pressure. Lying supine causes the leastComprehension Check
Intermittent traction is for a greater pull. It is used for distraction when neural foramina opening or retraction of herniated disc material is desired. Continuous traction is used for prolonged muscle stretch, such as in muscle relaxation
For posterior distraction, forces> 50 pounds are needed. For anterior separation, forces > 100 pounds are neededAnswers
The goal of the CPM is to prevent scar tissue from developing and decrease the problem of stiffness
Manipulation is a passive, high velocity, low amplitude thrust applied to a joint complex within its anatomical limit. PTTs are NOT allowed to perform manipulation
