why do pts experience pain with prolonged positions with age related joint changes
synovial fluid is squeezed out without ability to refill
202
what would you expect to observe and find in the scan with age related joint changes
observation - possibly forward head posture
ROM - pain with ext, ipsilateral SB, contralateral RT
- capsular pattern of restriction
CM - consistent block often in ext quadrant or opposing quadrants consistently blocked
RST - depends
ST - (+) compression, particularly in ext, ipsilateral SB, contralateral RT
- (+) PA and unilateral torsion
neuro - (-), could be (+) for radiculopathy
203
what would you expect to find with accessory motion tests with age related joint conditions
hypomobility
204
what is the PT rx for age related joint changes
greater focus on improving integrity of cartilage and mobility
POLICED
JM for pain, cartilage integrity and mobility
205
what is the focus of MET with age related joint changes
ultimate focus on improving motion, cartilage integrity, neuromuscular benefits
206
describe stenosis
narrowing around and compression of neurological structures
207
what is the prevalence of stenosis
most common dx for spinal sx in adults > 60 yrs
30% asymptomatic individuals had canal narrowing on imaging
208
what are the 2 ways compression of the spinal cord occurs with stenosis
inflammation of the sheath around the nerve and becomes fibrotic - nerve can't expand
spurring/narrowing of spinal canal
209
compression from the outside in with stenosis is due to...
age related disck and joint changes - most common
instability - older and younger
enfolding of lig flavum
210
what are the typical symptoms of lateral stenosis
unilateral LE > LBP
segmental paresthesias
gripping type pain d/t ischemia
211
what will decrease symptoms with lateral stenosis
forward bending
sitting
in morning - disc is more hydrated = more space
incline walking
212
what will increase symptoms with lateral stenosis
standing and walking
213
what would you observe with a pt that has lateral stenosis
slouched
possible scoliosis
214
what ROM would increase pain with lateral stenosis
extension
ipsilateral SB
215
what ROM would decrease pain with lateral stenosis
flexion
contralateral SB
216
what would you expect to find with neuro and stress tests for lateral stensosis
(+) neuro for radiculopathy
ST (+) PA pressures/torsion when sustained
217
what would you expect to find with accessory motion with lateral stenosis
hypomobility in lumbar flexion and contralateral SB
adj joint hypermobility in lower throacic and LE (hip)
218
what would you expect to find with lateral stenosis with special tests
stability test - excessive shearing
LE discrepancies (LLD, impaired mechanics)
balance deficits with wide based gait
Cooks CPR
219
what tests would you use to differentiate stenosis vs vascular symptoms
ankle-brachial index test for peripheral arterial disease
bicycle test
220
what is the bicycle test used to differentiate stenosis vs vascular symptoms
cycle upright then bend to lean on handlebars for 3 min each
is stenosis, pain will decrease with bent position. if it doesn't, PAD is indicated
221
what are the PT implications for stenosis
directed at foraminal opening
pt education of foramen and good prognosis
directional preference into flexion
intermittent traction may be helpful with radiculopathy
manual therapy
neural mobilizations
MET
222
what MET is benefical for stenosis
aerobic
balance training (physioball if unable to stand)
local muscle stabilization
223
when is surgery indicated for stenosis
presence of constant and/or worsening symptoms
failure to obtain relief within 3-6 months of nonsurgical treatments
224
what are the common surgeries that are utilized for LBP
laminectomy, partial discectomy
225
what is spondylolysis
bony defect or fracture of pars interarticularis unilaterally or bilaterally
226
what is the etiology of spondylolysis
congenital
repetitive stress (extension and rotation)
direct trauma
227
what spinal segments are most commonly involved with spondylolysis
L5-S1
228
what are the S&S of spondylolysis
acute - fracture S&S and (+) torsion test
persistent - asymptomatic, instability S&S if symptomatic
229
what are the 2 most common types of spondylolisthesis
isthmic or adolescent with spondylolysis
degenerative
230
describe isthmic or adolescent with spondylolysis
most common
age group with most rapid slipping
repetitive or traumatic extension
231
describe degenerative spondylolisthesis
d/t age related disc changes
>50 years old
no fracture
232
what are the S&S of spindylolisthesis
worse case of instability
possible lateral or central stenosis S&S with slippage
no correlation with lippage and degree of symptoms
233
what is the prognosis of surgery for spondylolisthesis
83% excellent to good outcomes with modified Scott technique
234
what structures are involved with facet joint impingement
meniscoid
facet joint
235
what are teh pathomechanics of facet joint impingement
meniscoid becomes wedged d/t prolonged position or quick movement
associated with instability
236
what are the S&S of facet joint impingement
woke up or made a quick movement and couldn't move
acuity with age related joint diseases S&S
underlying instability S&S
237
what is the PT rx for facet joint impingement
isometrics to use attaching multifidi to pull meniscoid out of the way
gapping manipulation
stabilization to address cause
inflammation, symptoms, and function often improve on its own before PT pursued
238
describe scoliosis
what are the 2 types
>/= 10 degree curvature
SB and contralateral rotation
structural, functional/postural
239
describe structural scoliosis vs functional/postural
structural = doesnt go away with FB
functional = goes away with FB, able to modify with PT
240
describe sway back posture
increased lumbar lordosis
anterior pelvic tilt
flexible body type
241
describe flat back posture
straight spine
flattening of normal curves
greater proportion of persistent LBP d/t less dissipation of forces
posterior pelvic tilt
rigid body type
242
describe rounded or crouched body posture
increased throacic kyphosis
flattening of lumbar curve
posterior pelvic tilt
often associated with FHP
