PTA135-Unit5-Spine Flashcards
relate the difference between Correct and Faulty Posture
correct - the position in which minimal stress is applied to each joint
faulty - any position that increases the stress to the joints
describe Ideal Standing Postural Alignment
Sagittal view, the plumb line:
• Passes through the ear lobe, the bodies of the C-spine vertebrae, the tip of the shoulder
• Midway through the thorax, through the bodies of the lumbar vertebrae
• Slightly posterior/midpoint to the hip joint
• Slightly anterior/midpoint to the axis of the knee joint
• Just anterior to the lateral malleolus
identify the characteristics of Normal Sitting Posture
“neutral” – 90-90-90 • ears over shoulders • Shoulders relaxed • Wrists straight • Elbows kept close to the body • Natural curve to lower back maintained • Feet resting on the floor
how to Instruct a Patient on the mechanics of lifting
use the Five L’s of Lifting
- When you lift, make sure you stand close to the object you are lifting (lever) with a wide stance and feet firmly on the ground. Bend at the knees and hips and make sure you lift with your legs and not with your back (lordosis). Make sure you do not pick up anything that is too heavy for you. Keep the load (what you are lifting) as close to your body throughout the lift as possible. Make sure you breathe when you lift, do not hold your breath. (Lungs)
name the 5 L’s of Lifting
Load Lever Lordosis Legs Lungs
explain the Load of lifting
The amount of weight to be hoisted should be appropriate for the task and for the individual attempting to lift it.
explain the Lever of lifting
Keep the object as close to the body as is functionally possible throughout the lift
• Holding an object away from the body increases the spinal compressive forces 10x
o a 5 lb. dumbbell away from the body, feels like 50 lbs. of pressure on the spine
explain the Lordosis of lifting
Maintain a normal anatomic lordotic curve (normal inward curve of lower back) while lifting any object
explain the Legs of lifting
Instruct individuals to lift with their legs and not with their back
explain the Lungs of lifting
Use proper breathing techniques during lifting. Valsalva maneuver (closed glottis during attempted expiration) should be AVOIDED
discuss Body Mechanics
All these L’s together comprise proper body mechanics.
“Body mechanics refers to the way we move during every day activities. Good body mechanics may be able to prevent or correct problems with posture (the way you stand, sit, or lie.) Good body mechanics may also protect your body, especially your back, from pain and injury. Using good body mechanics is important for everyone.” (http://www.drugs.com/cg/using-good-body-mechanics.html)
describe Peripheralization
- Radicular pain symptoms are experienced further down the leg.
- Do not want!
describe Centralization
- Radicular pain symptoms are made to move away from the periphery and toward the mid-line of the spine
- As a result of the performance of certain repeated movements or the adoption of certain positions
- Good! Yay!
1) Effect on the nucleus pulposus with positional change from flexion into extension
The nucleus moves anteriorly
2) Effect on the nucleus pulposus with positional change from extension into flexion
The nucleus moves posteriorly
rehab for Lumbar Spine Ligament Sprain
- Treatment parallels that of muscular strains
- Managed similarly to muscle strains
- Individualized treatment based on each patient’s impairments
- Emphasize protecting the spine from unwanted forces and positions
rehab for Lumbar Spine Muscle Strain
- Individualized for patient’s impairments
- Address pain and inflammation
- Specific stabilization and back strengthening exercises
- Flexibility in hips and lower extremity
- Cardiorespiratory conditioning
- Patient education!! Prevent reinjury!!
- Emphasize protecting the spine from unwanted forces and positions
define Ergonomics
a quantifiable system of job or ADL modification[ or redesign that allows for continued productivity while reducing work-related physical stress
define Functional Capacity Evaluation
FCE
• Mimics the work environment for improved training, similar to “Back School”
• A group of physical and functional tests administered to a recovering patient before he or she returns to the job.
• An FCE can also be used as a screening tool to acquire data related to pre-employment risk assessment and management of back injuries.
MOI of muscle strains of cervical spine
- Common among young athletes
- In association with motor vehicle accidents with flexion-extension, later flexion and acceleration-deceleration “whiplash” type injuries
- Falls
Muscles most often involved in muscle strain of cervical spine
- Upper trapezius
- Levator scapulae
- Scalenes
- Sternocleidomastoid (SCM)
- Spinal erectors
- Rhomboids
rehab for Cervical Strain
- Similar to treatment of lumbar strains
- Address pain and its causes
- AVOID the direction of the strain initially
- After inflammation and pain decrease, isometric contractions in all planes
- Progress to cervical stabilization strengthening
- Postural strengthening
cause of Cervical Spondylosis
Chronic degenerative disc
- “wear and tear on the weight bearing structures of the cervical spine”
most common cervical segments involved in cervical spondylosis
C5-C6
C6-C7
rehab for Cervical Spondylosis
• Address pain (NSAIDs)
• Avoid aggravating positions
• Semi-rigid cervical collar for some
◦ hopefully short term
• Axial Extension-retraction exercises are effective for patients who drive pain relief from extension
• Flexion-type activities are reserved for patients who obtain pain relief from cervical flexion
• Mechanical or manual cervical traction
• Cervical mobilizations (by the PT, of course)
• Isometric cervical spine exercises
• Posture mechanics, flexibility exercises, and strengthening activities
• Patient Education:
◦ Move on a regular basis
◦ Stretch throughout the day
◦ Posture – good sitting posture, ergonomics
◦ Sleep
- one pillow under head in supine
- pillow between knees and two pillows under head in sidelying
- Neutral spine top to bottom
name the 2 layers of an intervertebral disc
- Annulus
- Nucleus Pulposus
describe Annulus
– outer wall
• 12-18 concentrically arranged rings of fibroelastic cartilage
• No blood supply, cannot heal itself
• Anueral (gets nutrients from movement) except outer fibers
• Provides stability and withstand tension-torsional forces and bending
describe Nucleus Pulposus
– water binding mucopolysaccharide gel
• Transmits forces
• Equalizes stress
• Promotes movement
