Practice Stations II: Technique Walk Throughs and Final Preparation

A technique station is a short performance with a script: confirm the patient is safe to treat, find the listing, explain and consent, then build the set up piece by piece while you say what you are doing. This final chapter rehearses that script for the spine, the pelvis and the extremities, shows you how to run a realistic mock circuit with classmates, and closes with a plan for the last week and the morning of the exam.

Section 1Cervical and thoracic technique station walk throughs

The technique station script

Practical technique stations are generally scored on observable steps rather than on whether a cavitation occurs. Many stations ask you to set up and verbalize, or to take the set up to tension without delivering a thrust; the station instructions tell you which, and you must follow them exactly. Check the current official candidate materials for how thrusts are handled, what equipment is provided and what the examiner will and will not answer. Whatever the format, the same skeleton earns the points:

Notice that the verbal track does three jobs: it shows the examiner you know the anatomy (named contact points), it keeps the patient informed (consent and comfort checks), and it gives the examiner evidence for items that are hard to see, such as the line of drive. A silent, technically perfect set up can score worse than an average set up that is clearly narrated.

Naming listings in a station

Listing systems differ. Some describe the static position of a vertebra relative to the one below (for example, a body rotated posterior on the right), others describe the motion restriction found on motion palpation (for example, restricted left rotation). In this book's diversified style set ups, the listing is stated as a motion restriction together with the side of the posterior, tender structure. The two descriptions agree: a vertebra whose body is rotated posteriorly on the right resists rotating to the left, and the corrective contact goes on the posterior (right) side, driving it anterior. If the door card uses a different listing convention, translate it into "which side is posterior, which motion is restricted, which way must the segment move" before you touch the patient.

Cervical set ups

Safety in the neck

Before any cervical set up, ask about dizziness, visual disturbance, new or unusual headache, recent trauma, inflammatory arthritis (rheumatoid arthritis and Down syndrome bring atlantoaxial instability), anticoagulation, osteoporosis and prior neck surgery. Watch the patient's eyes and face during pre-load. Avoid sustained end range rotation combined with extension, and use the minimum force and the least rotation that localizes the segment. Absolute contraindications in the neck include fracture, instability, suspected arterial dissection, myelopathy, tumor or infection at the segment, and cervical fusion at the level. If the patient reports dizziness, nausea, visual change, numbness or speech difficulty during set up, stop, return the head to neutral, keep the patient lying down, check neurologic signs, and activate emergency care if signs persist.

Thoracic and rib set ups

The thoracic facets are oriented close to the frontal plane (inclined about 60 degrees from horizontal), so thoracic lines of drive run largely posterior to anterior with an inferior to superior component that follows the facet slope. Thrust on exhalation, when the rib cage is least resistant. Prone moves suit extension and rotation restrictions; the supine anterior thoracic move (the patient's arms crossed, the doctor's hand under the spine as a fulcrum) suits flexion restrictions.

Section 2Lumbar and pelvic technique station walk throughs

Side posture: the core lumbar set up

Side posture is the workhorse of diversified lumbar technique, and examiners watch its components closely because each one controls where the force goes. The patient lies on the side, the bottom leg straight, the top hip and knee flexed with the top foot resting in the popliteal fossa of the bottom leg. The doctor flexes the top leg until motion reaches the involved segment (palpate the interspinous space to feel it arrive), rotates the patient's upper shoulder posteriorly by drawing the bottom arm out, and rolls the pelvis toward the doctor until tension localizes at the segment. The doctor stands facing the patient in a fencer stance, with the inside thigh against the patient's flexed top knee or thigh, ready to drop the body weight through the contact.

The side of the patient that faces up is chosen so that the thrust drives the posterior structure forward. For a vertebra whose body is rotated posterior on the right (right mammillary prominent, left rotation restricted), the patient lies with the right side up. Two contacts then work in the same direction: a mammillary push on the up side (right) mammillary process, driving posterior to anterior, or a spinous pull on the down side (left) of the spinous process, pulling the spinous toward the ceiling. Both rotate the vertebra to the left, correcting the right posterior rotation (Figure 14.2).

Safety in the low back and pelvis

Before side posture, screen for the conditions that change the set up or forbid it: cauda equina symptoms (no manipulation, emergency referral), a progressive neurologic deficit, suspected fracture or osteoporosis, abdominal aortic aneurysm, tumor or infection, hip replacement (excess flexion and adduction of the top leg can dislocate a posterior approach prosthesis), recent lumbar surgery or fusion, and pregnancy (use side lying with support, avoid strong rotation and prone positioning late in pregnancy). With an acute disc lesion and leg pain, many clinicians prefer flexion distraction or positions that centralize symptoms rather than a rotational thrust. If leg pain increases or spreads during pre-load, stop, release the position and choose a different approach.

Section 3Extremity technique station walk throughs

Principles that apply to every joint

Extremity set ups follow the same script as spinal ones, with three additions. First, test and compare joint play on both sides before you decide on a listing; the restricted glide is the listing. Second, use the convex concave rule to choose a glide: when a convex surface moves on a concave one (the humeral head in the glenoid, the femoral head in the acetabulum), the joint surface glides opposite to the movement of the limb, so a restriction of shoulder abduction calls for an inferior glide of the head; when a concave surface moves on a convex one (the tibia on the femur, the phalanges on the metacarpal heads), the glide is in the same direction as the limb. Third, place the joint in its resting (loose packed) position for distraction and glides, where the capsule is most lax, and keep the stabilization hand close to the joint line so the force acts across one joint only.

Safety at the extremities

Screen every extremity station for fracture (apply the Ottawa rules after trauma), joint replacement (no thrust across a prosthesis; a hip replaced through a posterior approach must avoid flexion beyond 90 degrees combined with adduction and internal rotation), acute inflammatory or septic arthritis (hot, swollen joint with fever is an emergency), ligamentous instability (do not thrust a lax joint in the direction of laxity), bone tumor, open growth plates in children (use gentle mobilization), and severe osteoporosis. For the hip long axis distraction, an unstable or replaced knee means you grasp above the knee instead of at the ankle. For cuboid and fibular techniques after a sprain, wait until fracture has been excluded and acute swelling allows a comfortable set up.

Section 4A full mock station circuit

Why a mock circuit works

Reading about stations builds knowledge; running them under a clock with a stranger watching builds performance. A mock circuit reproduces the three stressors that degrade skill on exam day: time pressure, observation, and switching rapidly between unrelated tasks (a film, then a neck station, then a pelvic set up). It also exposes habits you cannot see yourself: skipping hand hygiene, forgetting consent, mumbling the line of drive, or spending half the station on history. Run at least two full circuits in the final month, and a shorter one in the final week.

Roles and materials

A group of four to six works well. Rotate roles so everyone performs and everyone scores.

Write door cards that resemble real ones: patient age and sex, chief complaint, vital signs, and a clear task ("perform a focused history and examination", "set up and verbalize; no thrust", "record your findings, impression and recommendation"). Each case needs a patient script (answers to likely questions, findings to report when each test is performed, and any cue such as a red flag symptom to reveal only when asked) and a scoring sheet. Build cases from the walk throughs in this chapter and Chapter 13, and include at least one station in each circuit that should end in a referral, so that the group practices stopping.

Timing

Use the station length and reading period stated in the current official candidate materials. If you do not yet have them, choose fixed values for the session and keep them identical across stations so the group learns to pace. Give a warning signal before the end of each station, and stop candidates at the signal even mid sentence: on exam day the station ends whether you are finished or not. A useful pacing target for a case management station is to finish the history by about 40 percent of the time, the examination by about 80 percent, and to reserve the last 20 percent for findings, plan and consent. For technique stations, aim to finish screening and consent in the first quarter so that most of the time goes to the set up and narration.

Scoring sheets

Score observable behavior with a checklist, marking each item done, partly done or not done, and flag critical items separately: missing one should fail the station in your mock regardless of the total, just as safety omissions can on a real practical exam. The sample sheets below are practice tools built from this book's walk throughs, not official forms.

A case management sheet follows the same pattern with sections for the history (chief complaint and OPQRST, red flag questions, medications and history), the examination (vitals, inspection, palpation, range of motion, orthopedic and neurologic tests appropriate to the complaint), the assessment (a reasonable diagnosis and differential), the plan (orders, management, home care, follow up), communication (plain language, empathy, teach back, consent) and critical items (the region's red flag screen and correct referral when indicated). Add a short global rating (for example, 1 to 5 for organization and professionalism) because examiners form an overall impression that a checklist alone does not capture.

Giving and using feedback

Keep feedback short, specific and actionable. A good format is: one thing done well, the critical items missed (if any), and one fix for next time. "Your line of drive was vague" is less useful than "say both components, posterior to anterior and inferior to superior." Record each candidate's missed items across circuits; patterns (always forgetting blood pressure, always running out of time before consent) are the most valuable output of the whole exercise. Repeat the same station a few days later to confirm that the fix holds.

Section 5The week before and the day of the exam

The shape of the final week

The final week is for consolidation, not new learning. By now the films, cases and set ups are in place; what remains is to keep them fluent, protect sleep, remove logistical uncertainty and arrive rested. Taper the volume of study through the week while keeping short daily practice, much as an athlete tapers before a competition (Figure 14.5). Learning new material in the last days tends to displace confidence rather than add points, and cramming late into the night degrades the very skills (recall under pressure, motor precision, attention to cues) that a practical exam tests.

Sleep and the body

Sleep is when practice becomes skill: motor sequences and declarative memories are consolidated during sleep, and even one night of restricted sleep measurably slows reaction time and impairs attention and working memory. Hold a consistent wake time across the whole week so that the exam morning feels like any other, aim for 7 to 9 hours nightly, and move your schedule gradually if the exam starts earlier than you usually wake. If the night before is restless, do not panic: a single poor night has much less effect on performance than a week of short sleep, and adrenaline on the day compensates for some of it. Keep caffeine at your usual dose (more than usual adds tremor and anxiety, and its half life of about five hours means a late afternoon coffee can still be active at bedtime). Avoid alcohol in the final days because it fragments sleep. Eat familiar food; exam morning is not the time for a new breakfast. Keep exercise light and familiar so you do not arrive sore.

Logistics checklist

Uncertainty about logistics consumes attention you need for stations. Settle every item by two days out and lay out what you will bring the night before. Follow the current official candidate materials for identification, admission documents, required attire, permitted and prohibited items, arrival time and conduct rules, because these vary and change.

• Documents: the identification and admission materials required by the official instructions, with names matching exactly.
• Route: address, travel time with a generous buffer, parking or transit, and a backup route; for an unfamiliar city, consider staying nearby the night before.
• Attire: professional clinic clothing that allows you to move, kneel and lean; short or easily rolled sleeves for hand hygiene; trimmed nails; no strong scent.
• Permitted items: only what the official instructions allow (for example, specific examination tools); leave everything else in the car or at home.
• Body: water, a simple snack for breaks if allowed, any personal medication.

Managing nerves

Some arousal improves performance; too much narrows attention, speeds speech and makes hands clumsy. The goal is not to remove nerves but to keep them in a useful range. Three tools work well and can be practiced during mock circuits so they are automatic on the day. Slow breathing: a long exhale activates parasympathetic tone; try box breathing (in for 4, hold for 4, out for 4, hold for 4) or a double inhale through the nose followed by a slow full exhale, repeated two or three times. Reappraisal: label the racing heart as readiness ("my body is preparing me to perform") rather than as a sign of failure; this simple reframe has been shown to improve performance under evaluative stress. A door routine: the same short sequence at every door (breathe out, read the card twice, name three differentials or the set up, picture the first sentence you will say, knock) keeps you in the present station instead of the last one.

Between stations, reset. A station that went badly is over and its score is fixed; the next station is a fresh opportunity, and dwelling on the last one is the most common way a single error becomes several. If you blank during a station, fall back on the sequence: "Let me summarize what we have so far," or return to the next step of the checklist (screen, consent, examine, plan). The sequence carries you until the content returns.
