A different first question
You have already met the idea that gives this whole rung its shape: rehabilitation lives or dies on measurement, and the language it measures in is the ICF model — body structures, the activities a person can carry out, and the life they get to participate in. The physiatric exam is where that model first touches a real human being. So before any reflex hammer comes out, notice what makes the opening question strange. A cardiologist asks, in effect, *what is wrong with your heart?* A physiatrist asks that, and then leans in and asks the question that organizes everything after it: what can you do, and what is getting in your way?
This is not a softer question; it is a harder one. Two people can carry the identical lesion — say, a stroke that has weakened the same patch of brain — and lead completely different lives. One returns to work and cooks dinner; the other cannot get from bed to the toilet alone. The MRI looks nearly the same for both. The difference lives entirely in the territory the physiatric exam is built to map: the gap between an impairment in the body and a limitation in daily life. Holding that gap in view is the single habit that separates the physiatric history and examination from the disease-hunting exam you may already picture when you hear the words *medical history*.
The history that listens for a day, not a disease
A standard medical history chases a diagnosis: when did the pain start, what makes it worse, any fevers. The physiatric history keeps all of that and then adds a second spine running alongside it — the functional history, which walks a patient through an ordinary day and asks how each piece of it actually gets done. Can you roll over in bed and sit up on the edge? Stand from the chair without pushing on the armrests? Get to the bathroom in time, manage the toilet, the shower, the buttons on your shirt? Climb the three steps at your front door, where there is no handrail? Each answer is a sentence in the language of activities and participation, and together they sketch the life the rehabilitation will actually be aimed at.
Then the history widens past the body entirely, because function never happens in a vacuum. Where do you live — a fifth-floor walk-up, or a bungalow? Who is home with you, and what can they help with? What did you do for work, and do you need to return to it? What did you love doing on a Saturday that you have stopped doing? These are not pleasantries. A grab bar, a relative who can transfer you, or a workplace willing to adapt can matter more to a real outcome than any single point of muscle strength. This is the personal and environmental context the ICF model insisted on, now collected one honest question at a time.
Inspection: the exam begins before you touch anyone
The hands-on exam opens with the cheapest and most underrated tool there is: looking. A skilled physiatrist is reading a patient from the moment they appear in the waiting-room doorway. How do they rise from the chair — do they rock forward and push up on both arms? How do they walk over, and is one arm held bent and tucked against the chest while the matching leg circles outward to clear the floor? That posture is a textbook picture you will meet again under stroke, and it was visible across the room, for free, before a word was exchanged.
Up close, inspection becomes systematic. The clinician compares left to right, because the body's own healthy side is the best ruler it owns. They look for muscle that has wasted away to a hollow where it should be full — the atrophy you read about under disuse — and for swelling, bruising, scars from old surgery, or the reddened pressure point over a bony prominence that warns of a brewing skin injury. They watch the resting posture of a limb: a hand curled tight, a foot pointing down and in. None of this requires touching the patient yet. Inspection is the wide-angle photograph; everything that follows zooms in to confirm or overturn what the eyes already suspected.
Range of motion, and the protractor that pins it down
Now the exam moves the joints. You met range of motion back in the kinesiology rung as the arc a joint can travel through, and the named joint movements — flexion, extension, abduction, and the rest — that describe that travel. In the exam this becomes a hands-on test with a crucial split. First the clinician asks the patient to move the joint themselves: active range of motion, which tests willingness, muscle, nerve, and joint all at once. Then the clinician gently moves it for them, the patient relaxed: passive range of motion, which takes the muscles' effort out of the picture and tests the joint and its soft tissues alone.
That split is a small diagnostic machine. Suppose a shoulder will only lift halfway when the patient raises it themselves. If you then move it for them and it sails up to the full arc, the joint is fine — the problem is in the muscle or its nerve, a story for manual muscle testing. But if it stops dead at the same halfway point however gently you push, the limit is mechanical: a stiffened, shortened joint, the contracture you met in the immobility guide. Active and passive almost the same, but both reduced and painful at the end, points somewhere else again. The two numbers, side by side, already tell you which kind of problem you are dealing with before you have named the cause.
To turn "about halfway" into a number a colleague three weeks from now can compare against, the physiatrist reaches for a goniometer — literally an angle-meter, a clear plastic protractor with two arms. One arm lines up with the bone that stays still, the other with the bone that moves, the center sits over the joint's axis, and the dial reads the angle in degrees. This is goniometry, and its whole purpose is to replace a vague impression with a repeatable figure: this elbow extends to 30 degrees short of straight today, against 45 degrees last month. That is progress you can defend.
GONIOMETRY — recording the SAME joint, three ways
AROM active range of motion patient moves it -> tests muscle + nerve + joint
PROM passive range of motion examiner moves it -> tests joint + soft tissue alone
Notation: ELBOW 0 deg = fully straight, ~145 deg = fully bent
Normal elbow ............ 0 -> 145 (full arc)
Flexion contracture ..... 30 -> 145 (cannot straighten the last 30 deg)
Reads aloud as: "lacks 30 degrees of extension; flexes to 145"
One joint, one shared zero point, degrees -> two people can compare across weeks.Palpation: the trained hand as an instrument
Where the eyes and the goniometer leave off, the hands take over. Palpation is examining by touch — pressing, feeling, and moving tissue to gather what cannot be seen. The clinician feels along a muscle for the exquisitely tender knot of a trigger point, presses over a tendon to find the precise spot that reproduces a runner's heel pain, feels the warmth and boggy fullness of an inflamed joint, traces a bony landmark to confirm a fracture is healing in line. The skill is half knowing the anatomy under your fingertips cold, and half developing a touch sensitive enough to tell a tense muscle from a relaxed one, a fluid-filled swelling from a firm one.
Touch also reads things that have no other window. When the clinician moves a relaxed limb through its range, the hand is feeling for muscle tone — the resistance the muscle offers when it should be at rest. A limb that flops loose, one that resists like a stiff hinge, one that catches and then suddenly gives way: each feels distinctly different, and that felt quality is the raw material the scales in a later guide will try to grade. But here is an honesty the field insists on early — feeling more resistance is not automatically a thing to abolish. Some tone in a paralyzed leg actually helps it bear weight for standing; the question is never simply *is there resistance* but *does it help this person do something, or does it get in the way?* That judgment, again, is the function-first habit returning in a new disguise.
Why this exam reads a person, not only a lesion
Step back and see what the whole sequence was for. The history mapped the day and the life. Inspection took the wide photograph. Range of motion, pinned by goniometry, turned stiffness into a defensible angle. Palpation let the hand read tone, tenderness, and texture. Notice that every one of these feeds a single integrated picture, and that the exam refuses to stop at the lesion. A neurologist might be satisfied to localize the damaged spot and name it. The physiatrist treats that as the opening line, then asks the sentence that follows: given this body, in this home, with this work to return to, what can this person do, and what is the cheapest, strongest lever to help them do more?
One last truth to carry forward. This exam is rich, but it is also subjective at its edges: how far a shoulder "really" moves, how tender a spot "really" is, how much a tone "really" resists, all wobble a little from one examiner to the next and one day to the next. That wobble is not a flaw to be embarrassed by — it is the precise reason the rest of this rung exists. The exam tells you where to look and turns the looking into the beginnings of numbers; the standardized scales of functional assessment — the FIM, the Barthel Index, the Berg balance scale, gait speed — take those beginnings and forge them into measures stable and shared enough that a whole team, and the patient, can watch "doing better" become a line that climbs. That is exactly where the next guide picks up.
