Running Gait Physical Therapy in Flagstaff, AZ
Filmed at 240 frames a second from six angles, read against twelve weeks of your training data. Most running injuries are a load problem wearing a biomechanics costume.
Runners, and Almost Only Runners
Eight years of one sport means we've seen your injury a few hundred times, at this altitude, on these trails.
Gait Analysis
Treadmill capture at 240fps from six angles, plus overground filming outside. Cadence, vertical oscillation, foot strike, hip drop, knee window and trunk lean, all measured rather than eyeballed.
Training Load Review
Twelve weeks of your actual data. Acute-to-chronic ratio, weekly ramp, surface and elevation mix. The answer is in here more often than it is in your hips.
Strength for Runners
Heavy, specific and brief. Calf raises to real load, hip work that progresses past a band, and plyometrics staged properly. Two sessions a week, forty minutes, no gym membership required.
Bone Stress Injuries
Shins, metatarsals, femoral neck, sacrum. Graded loading, and a frank conversation about energy availability — because repeat bone injuries in runners are very often a fuelling problem.
Achilles & Plantar Care
The two that respond beautifully to loading and terribly to rest. Isometrics, then heavy slow resistance, then energy storage. Twelve weeks, and it works if you do it.
Altitude & Trail Load
Seven thousand feet changes your recovery, and vert loads tissue differently from flat mileage. People who move here get hurt in month two with striking reliability, and it is avoidable.
Ninety Minutes, Six Cameras, One Spreadsheet
You leave with the video, the numbers and two or three things to change. Not twenty.

Eight Years at Seven Thousand Feet
Northmoor is on South Beaver Street because that is where the runners are, and it treats runners because that is what we are.
Specialising this narrowly means the pattern recognition is unusually good. When someone describes lateral knee pain that starts at forty minutes and only on downhills, we have seen that specific presentation a great many times, in this town, on these trails, at this altitude.
It also means we are honest about what running injuries actually are. Most of them are not a broken body — they are more load than the tissue was ready for, applied faster than it could adapt. That reframe changes the treatment entirely, and it is why we ask for your training data before we ask you to lie on a table.

The Five Stages, and What Ends Each One
Nobody gets moved on by the calendar.
Settle the Tissue
Reduce the aggravating load without stopping everything — complete rest deconditions tendon and bone and makes stage four harder. Cross-training keeps the engine while the tissue calms down.
Load It Properly
Heavy, slow, progressive. Calf raises with real weight for Achilles, graded impact for bone. This is the stage that gets skipped and the reason so many runners are on their third recurrence.
Walk-Run, Measured
Structured intervals with a defined progression and a symptom rule: acceptable during, settled within twenty-four hours. If it isn't, we step back one stage rather than pushing on.
Rebuild the Volume
Back to continuous running, ramping under ten percent a week, flat before hills, road before trail. Vert and technical terrain are added last because they load everything hardest.
Add the Sharp End
Speed, downhills and long runs — the three things that cause recurrences. Reintroduced one at a time, a fortnight apart, so if something flares we know exactly which one did it.

Ten minutes from the trailheads everybody actually trains on.



Mostly People on Their Third Attempt
Two physios told me to stretch my IT band and rest. He looked at my training log, found I'd added thirty percent of mileage in three weeks, filmed me running, and changed my cadence by six steps a minute. Pain gone in a month.
Third stress fracture in four years and nobody had ever asked about my eating. That conversation was uncomfortable and it was the single most useful thing anyone in medicine has done for me.
I moved here from sea level and got hurt within two months, which I now understand is completely predictable. They rebuilt my load from the ground up around altitude and I've had a clean eighteen months since.
Fifty-two, back to back-of-the-pack ultras, and expecting to be told to take up swimming. Instead I got a strength programme and a plan. Finished Stagecoach with the knee behaving itself.
Booking, Cost and What to Bring
No Referral Needed
Arizona has direct access — book straight in. If your plan wants a referral for reimbursement we'll tell you before your first visit.
$225 Gait Analysis, $130 Follow-Ups
Published. The analysis runs ninety minutes and includes the video files and the written programme. Superbill provided for out-of-network claims.
Bring Your Training Data
A Strava or Garmin share link is ideal. Twelve weeks is enough. If you don't track, bring your best honest recollection of the last three months.
Bring Every Pair of Shoes
All of them, including the retired ones. Wear patterns and midsole compression tell us things you can't remember, and shoe rotation is a real variable.
Wear What You Run In
Shorts, ideally — we need to see knees and hips. There's a changing room and a shower if you're coming from a run.
You Keep the Footage
All six angles, slowed and annotated, in your inbox that afternoon. It's yours — send it to your coach if you have one.
What Runners Ask
Do I need to stop running?
Usually not entirely, and that's deliberate. Complete rest deconditions tendon and bone and makes the return harder. More often we reduce and modify — less volume, flatter, slower — while loading the tissue properly. Occasionally full rest is genuinely necessary and we'll say so.
Will you change my foot strike?
Probably not. Foot strike is far less important than the industry suggested for a decade, and forcing a change often shifts load somewhere unprepared for it. Cadence, step width and hip control are usually more useful and much easier to change.
Are my shoes the problem?
Rarely the whole problem and occasionally part of it. Shoes matter mostly when you change them abruptly or run everything in one worn-out pair. Bring all of them and we'll look — but expect the training log to be more interesting.
I'm slow. Is this for serious runners only?
About two-thirds of our patients run under thirty miles a week and a good number came to running in their forties or later. Injury doesn't care how fast you are, and neither do we.
Why does altitude matter?
At seven thousand feet the cardiovascular cost of a given pace is higher, so people run by feel and end up doing more mechanical work than they think. Recovery is also slower. Runners who move here reliably get injured around month two — it's the commonest story we hear.
How long until I'm racing again?
It depends on the tissue. Tendon is typically eight to twelve weeks of proper loading; bone stress injuries run twelve to twenty. Muscle strains are quicker. You'll get an honest range at the first visit, with stage criteria rather than dates.
