lower back assessment Flashcards
Objectives of physical examination
to find
- a mechanical basis for problem
- a comparable sign
- the structure at fault
- accurate/reproducible signs to allow monitoring of treatment response
- particularly to look at ways of off-loading painful structures / spinal segments
CAUTION++ IF PATIENT COMPLAINS OF
- difficulty passing bowels/urine (inability to know when to go
- urinary retention not just constipation due to pain on passing motion)
- saddle anaesthesia, A&E caution given
- muscle weakness in lower limbs
- specific dermatomal loss of sensation
- or bilateral pins needles and/or numbness
- severe night pain
- severe pain reproduced on cough/sneeze
STANDING
Observation from behind
6
- breathing pattern – diaphragmatic; lifting
- levels, lateral shift, scoliosis, Lx lordosis (pivot point), Tx kyphosis
- crease lines - areas of increased flexibility (extension, side flexion)
- lower limb rotation and foot posture
- muscle - activity of erector spinae &/or hamstrings; adductor muscle
- muscle - decreased gluteals; atrophy (wasting) e.g. OA hip = postero lateral aspect
Standing Observation from side
- breathing pattern – diaphragmatic; lifting
- muscle bulk – abdominals
- Lx lordosis, pelvic tilt, Tx kyphosis, Cx lordosis, knees locked & effect on spine, sway & effect on gluteals (see plumbline posture assessment)
Palpation- superficial
- temperature
- muscle - activity of erector spinae Lx & Tx, quadratus lumborum, latissumus dorsi, hamstrings
- lateral expansion lower & higher
Quick tests for other joints (hip, knee and ankle if needed)
- hip movement when taking trousers & socks off
- sitting hip flexion movement
Standing Neurological muscle tests
S1- standing test, unilateral toe raise x 5 each leg (hold patients hands)
- S1 – walking on tip toes
- L4 and L5 - Walking on heels
Active Lx movements (quantity & quality)
- instruct patient to move fingers down legs and record P and R as appropriate
- lateral side flexion – pivot points, spinal curve
- flexion – catching pains, return to neutral
- extension – pivot points
10
Dynamic posture
· walking
- lack of Tx rotation
. - lack of arm swing
. - pelvis shifting laterally on weight bearing each leg (possible gluteal weakness)
. - shoulder level on weight bearing each leg (possible gluteal weakness
. - palpate gluteal muscles on weight bearing leg
. - decrease contraction in compared to other side
. - decrease holding time in compared to other side
. - hip movements – decreased extension, quads tight, effect on pelvis & Lx
. - knee snapping into extension
. - heel toe gait, heavy landing, heel control
dynamic posture· standing 1 leg
- leaning
- pelvis shifting
- gluteals
- hand on side of pelvis & repeat
dynamic posture · ¼ squat
- picking up, front-on?, lx v’s hips & knees in both flexion & extension
- at sink, lx v’s hips & knees in both flexion & extension
· sitting
observation
- slump, neutral or extended – sitting bones / ischial tuberosities
- lateral expansion lower & upper
- Tx rotation, side flexion
Passive accessory intervertebral movements (PAIVMs)
- shapes & sizes of spinous processes
- transverse pressures
Palpation soft tissues & ribs
- activity of erector spinae mid-thoracic to lumbar, quadratus lumborum, latissumus dorsi, upper buttocks, lateral buttocks, ITB
- rib movement
- intercostal movement
Muscle length tests / Neuromuscular sensitivity test
· iliopsoas / femoral nerve stretch (FNS)
Neurological examination
- muscle tests
- sensation - light touch / sharp to upper leg and lower leg (circular checks), feet
- cord signs – Babinski, Hoffmann’s and clonus tests
Quick tests for other joints
- hip quadrant, knee, ankle as appropriate
- SI joint compression and distraction via iliac crests
- SI joint - hip flexion, palpate SI joint while compressing through the femur
Neuromuscular sensitivity tests
SLR
Passive accessory intervertebral movements (PAIVMs)
- uni-lateral postero-anterior pressures on tissue over articular pillar
- central postero-anterior pressures on spinous processes
- transverse pressures on spinous processes
DIFFERENTIAL DIAGNOSIS
- fracture if traumatic injury
- referred pain from abdomen
- secondary to cancer eg. prostate, testicular, pelvis region, lung,
- aortic aneurysm
