36
Cord signs test
babinski
run blunt object on plantar aspect of foot from heel along lateral border of foot across MTP heads to head of 1st MT.
* Great toe ext & splaying of toes = +ve response.
* Great toe flex = -ve response
37
Cord signs test
clonus
quick repeated passive ankle dorsiflexion.
* Repetitive tremor = +ve response
38
Cord signs test
Hoffman’s
Flick middle finger distal phalanx into flexion.
* Index finger & thumb start to move together = +ve response
39
Tests for sensation
* light touch - use cotton wool
* sharp - use sterile needle/pin wheel in case break skin
* Perform each of the above on the low back, legs (circular checks) and feet
Areas of altered sensation are related to dermatomal spinal origin (nerve root or sleeve) or to peripheral sensory nerve
Test and then map any area of altered sensation by moving from area of altered sensation to areas of normal sensitivity
40
sensory assessment findings
· increased - hyperalgesia
· dulled - hypoalgesia
· nil - analgesia
· altered - dysaesthesia
41
vascular changes observation
colour
* white/blanched - arterial
* cyanosed/bluish - venous
.
* engorgement of superficial veins of limb - venous
* slow response to nail pressure - arterial
* deep vein thrombosis - pain, tenderness, hot, red, pain on stretch, pain weight bearing
42
find the L5 spinous process
* slide up off the sacrum until a spinous process is located deep at the centre of the lumbosacral depression
* to reconfirm that this is the L5 spinous process find the PSIS and draw an imaginary line at a 300 angle (from the horizontal) and the same spinous process should be located
42
43
Feeling of spinous processes
- L5
- L4-1
- L3
- T12
* the apex of the spinous process of L5 is small and rounded
* L4 to L1 are quadrilateral
* with L3 being the longest
* T12 is rounded
44
Aim of PPIVMs and PAIVMs
* assess the physiological and accessory glide movements of each spinal segmental level in an attempt to diagnose the segmental origin of the patient’s complaint.
45
The criteria for segmental diagnosis
is the detection of **abnormal quality of intervertebral movement**, associated with the perceived presence of through range and end range alterations in tissue resistance (such as that provided by muscle spasm / guarding) and the **reporting of pain provocation** during the process of manual examination.
46
difference in tissue resistance feeling
Older changes in tissue resistance may feel thicker, whereas more recent changes may feel softer
47
accessory glides on acute injury segment may cause
In acute injury segmental muscle spasm may be provoked during gentle accessory glides.
48
Hypermobile accessory
Hypermobile or unstable joints may feel “boggy”, with a noticeable increase in accessory movement unless prevented by alterations in tissue resistance such as muscle spasm / guarding.
49
pain reproduction - manual therapy
The pain reproduced may be local to the area where the technique is being performed or pain could be referred to an area where the patient is complaining of symptoms eg. in the buttocks/legs.
Reproduction of the exact symptomatic complaint of the patient assists greatly in deciding the segmental origin of a patient’s complaint.
