Describe the hemiplegic gait?
Patient lurches their upper body towards the unparalysed side to elevate the pelvis and swings the paralysed leg round. The plantar flexed foot of the paralysed leg scrapes the floor
26
Describe the apraxic gait?
Patient is slow and shuffling - stride lenght is markedly reduced and balance can be lost when turning - wide base. Parkinsons gait is this but with additional loss of arm swing and with narrow base
27
Describe the steppage gait?
Foot drop forces the patient to flex the knee and lift the foot high to clear their toes from the ground
28
Describe the ataxic gait?
Wide base, patient sways when walking - this will be most pronouced on heel-to-toe walking
29
Describe the MRC power score?
``` 5/5 = movement against gravity, full power against resistance 4/5 = movement against gravity and reduced power against resistance (4-,4 and 4+) 3/5 = movement against gravity only without applied resistance 2/5 = muscle contraction with active movment only when gravity is removed 1/5 = flicker of muscle contraction but no movement 0/5 = no muscle contraction ```
30
When is the forehaed sparred?
UMN lesions
31
What is Rinne's test? What does it show?
Place the tuning fork on the mastoid process until sound is no longer hears, then move to the external acoustic meatus (it should be heard again). Conductive hearing loss = sound is conducted better through bone and sound is not heard when placed next to the EMA Sensorineural hearing loss = sound is reduced equally in air and bone
32
What is Webber's test? What does it show?
Place the tuning fork on the forehead in the midline. Conductive hearing loss = sound is louder in the abnormal ear Sensorineural hearing loss = sound is louder in the normal ear
33
What can be seen on examination in cerebellar dysfunction?
Dysarthria (difficulty saying repeating letters or tongue twisters), dysmetris and intention tremor (tremor and overshooting in finger-nose test), nystagmus which is worse on looking towards the side of the lesion, ataxia, wide based stance and inability to walk heel-to-toe
34
How can you localise the lesion in cerebellar ataxia?
Vermis lesion = truncal ataxia | Cerebellum hemisphere lesion = ipsilateral limb ataxia
35
What bowel sounds can you hear that indicate pathology?
Tinkling bowel sounds = intestinal obstruction | No bowel sounds = peritonism
36
What sequence of exams should you do at the end of a GI exam?
``` ISHRUG Inguinal lymph nodes Stools Hernial orifices Rectal examination Urinalysis Genitalia ```
37
What movements of the shoulder are seen when: 1. Putting your hands behind your head and pushing the elbows back 2. Putting your hands behind your back
1. Shoulder abduction and external rotation | 2. Shoulder abduction and internal rotation
38
How can you asses joint effusion?
``` Patella tap (slide hand down the thigh towards the knee) Bulge test (slide hand around the knee) ```
39
What is Thomas' test? What is a positive test?
Assesses for fixed flexion deformity of the contralateral hip by flexing the ipsilateral hip fully +ve = the unflexed hip will lift off the bed. Indicates a fixed flexion deformity in the unflexed hip
40
What is Trendelenburg's test? What is a positive test?
Assess abductor strength in the contralateral hip by lifiting the ipsilateral leg off the floor +ve = the pelvis will drop on the side of the leg which is lifted off the ground. Indicates abductor pathology in the planted leg
41
Which muscles make up the hip abductors?
Gluteus medius, gluteus minimus, tensor fascia latae and sartorious
42
How can you test the cruciate ligaments?
Posterior draw test OR posterior sag test = PCL pathology | Anteror draw test = ACL pathology
43
How can you test the collateral ligaments?
Flex the knee to 20 degrees and apply a stress - look for gapping. Varus stress which causes lateral gapping = lateral collateral damage Valgus stress which causes medial gapping = medial collateral damage
44
What is McMurray's test? What does it show?
Flex the hip to 90 degrees and maximally flex the knee. Internally or externally roatate the knee then extend the knee gradually. Palpable/audiable/painful clicks on extension indicate a meniscal tear On external roation = medial meniscal tear. On internal rotation = lateral meniscal tear
45
Which nerve is responsible for toe extension?
Deep peroneal/fibular nerve (they are the same nerve)
46
Which nerves are responsible for toe flexion, abduction and adduction.
Medial and lateral plantar nerves
47
Foot drop and loss of inversion implies damage to which nerve?
Common peroneal/fibular nerve (they are the same nerve)
48
Plantar flexion is lost on damage of which nerve?
Tibial nerve damage
49
Eversion is lost on damage of which nerve?
Superficial peroneal/fibular nerve (they are the same nerve)
50
What is the straight leg raise test? What does it indicate?
With teh patient supine lift the leg (keep the knee extended) Pain in the leg or bak indicates a L4/L5/S1 nerve root lesion
51
What is the bowstring test? What does it indicate?
Carry out a straight leg raise. If the patient experiences pain flex the knee (this should reduce pain), then press in the popliteal fossa with the thumb. Radiating pain/parastehsia indicates tension of the sciatic nerve
52
What is the femoral stretch test? What does it indicate
Lie the patient prone and flex each knee in turn. | Pain in the front of the thigh indicates L2-L4 root damage
53
What is the first movement lost in frozen shoulder?
External rotation
54
What is the painful arc? What does it indicate?
Ask the patient to abduct their arm from their side to the sky. Painful arc = pain from 60-120 degrees - this indicates roator cuff pathology
55
What are the rotator cuff muscels?
Supraspinatus, infraspinatus, teres minor and subscapularis
56
How does pathology in each of the roator cuff muscles present?
Resisted active abduction in the first 15 degrees or empty can test = supraspinatus Resitsed active external roation = infraspinatus and teres minor Resisted acitve internal rotation (lift off test) = subscapularis
57
What is the scarf test? What does it show?
Place the arm into forced adduction across the body with the shoulder at 90 degrees flexion. Pain or tenderness over the Acromioclavicular joint indicates ACJ pathology
58
How do you confirm tennis elbow and golfers elbow?
Tennis elbow = pain in the lateral epicondyle when extending the wrist with the arm pronated Glofers elbow = pain in the medial epicondyle when flexing the wrist with the arm supinated
59
What is Allen's test?
Test the vascualr supply to teh hand (from the ulnar and radial arteries)
60
How can you test the median nerve?
``` Sensation over the median distribution Motor = palmar abduction (with the hand supinated ask the patient to point their thumb to the celing) Tinnels test (tap on the median nerve) and Phalens test (place the wrist in forced flexion) and Compression test (compress the carpal tunnel) - all should reproduce carpal tunnel symptoms ```
61
How can you test the ulnar nerve?
Sensation over the ulnar distrubution Motor = ask the patient to cross their middle and index fingers. Ask the patient to grip paper between their thumb and index finger without flexing the thumb. Ask patient to abduct their fingers against resitance
62
How can you test teh radial nerve?
Sensation in the anatomical snuff box | Motor = wrist and finger dorisflexion against resisitance
63
What are the nerve roots of the radial, medial and ulnar nerves?
``` Radial = C5-T1 Median = C6-T1 Ulnar = C8-T1 ```
64
What type of mass moves when swallowing? What type of mass moves when protruding the tongue?
Swallowing = thyroid mass | Tongue protrusion = thyroglossal cyst
65
What are the nerve roots of the sciatic and common peroneal nerves?
Sciatic = L4-S3 | Common peroneal nerve is a branch of the sciatic nerve using nerve roots L4-S2
66
What do raises in ALT and ALP respectivley indicate?
ALT increase = hepatocellular injury | ALP increase = cholestasis
67
What do the ALT to AST ratios indicate?
ALT > AST = chronic liver disease | AST > ALT = cirrhosis and acute (alcoholic) hepatitis
68
What is Schober's test?
Mark 10cm above and 5cm below the level of the posterior iliac spines. Ask the patient to lumbar flex - this gap should increase from 15 - 20cm
