Why Core Work in OT Doesn't Look Like Planks
Most people hear "core strengthening" and picture a sixty-second plank or a bunch of crunches. That's bodybuilding logic, not rehabilitation logic. In occupational therapy we're not building aesthetic abdominal walls. We're trying to make sure someone can get out of a low armchair without using their hands, carry a laundry basket upstairs, or sit through a two-hour meeting without their lumbar spine compressing into pain. The exercises look different because the goal is different. I spent seven years doing outpatient ortho and neuro cases before moving into purely geriatric rehab. The thing that annoyed me most was watching well-meaning PTs prescribe dead bugs and bird dogs to people who couldn't generate a single trunk curl without bracing their neck. The core isn't just abs. It's diaphragm, pelvic floor, multifidus, transverse abdominis, obliques, erector spinae, and the fascia that ties it all together. If you only train one link the chain breaks somewhere else. That's why our approach is modular and sequenced.
Occupational Therapy Core Strengthening Exercises For Adults
Here's what a real session looks like. I don't hand someone a mat and walk away. The first fifteen minutes are assessment — can they recruit transverse abdominis on command? I check by having them lie supine, place my fingers just above the pubic symphysis, and ask them to gently draw the belly button toward the spine without holding their breath. If they hold their breath or pull with their neck, we go back to breath work. No exercise happens until that connection is there. This step usually takes three to five minutes per person but I've had clients where it took twenty. The progression I use is six stages, not three. Stage one is diaphragmatic breathing with pelvic floor co-contraction. Lie on your back, knees bent or legs elevated on a chair if lumbar flattening is impossible. Inhale through the nose letting the ribs expand laterally — not up. Exhale fully and gently engage the pelvic floor and lower abdominals together. Hold for three seconds, release. Ten reps. That's it for week one. Most people think this is too simple. It's not. You're wiring the nervous system to fire deep stabilizers before superficial movers. Stage two adds dead bug variations but only the partial version. Supine, knees at ninety degrees over hips, arms reaching toward ceiling. Lower one heel to tap the floor, return. Then the opposite side. Range is two inches of leg travel, not full extension. Full extension before stage two recruits hip flexors and dumps the load into the lumbar spine. I see this mistake constantly in gym-goers who move to stage five before stage two is automatic.
Stage three is the modified plank. Knees down, body from shoulders to knees in a straight line, ribs down not flared. Hold twenty seconds. If the lower back sags even a centimeter the hold is wasted and possibly harmful. Progress to thirty, then forty-five. This stage usually takes three to four weeks of daily practice for deconditioned adults. Stage four introduces Pallof press variations using a resistance band anchored at chest height. Stand sideways to the anchor, hold the band with both hands at the sternum, press straight out against the rotational pull. Hold two seconds at full extension, return. Ten reps per side. This trains anti-rotation, which is far more relevant to daily function than pure flexion. Carrying a groceries bag, turning while pushing a walker, getting up from a couch after sitting on one side — these are all rotational tasks. Stage five is functional loaded carries. Farmers walks with moderate dumbbells, suitcase carries on one side only. Twenty meters each direction. The trick is keeping the rib cage stacked over the pelvis while walking. People lean away from the weight without realizing it, which defeats the purpose. I use a mirror or have them record video so they can see the lateral flexion. This stage builds what we call dynamic stability — the core working while the limbs move.

Stage six is the one nobody likes but everyone needs. Single-leg balance with trunk control. Stand on one leg, knees soft, reach the other foot forward to tap the ground and return without leaning. Or do a half squat on one leg while maintaining upright posture. Fifteen reps per side. This integrates the entire kinetic chain. The core stabilizes the spine while the hip abductors and ankle stabilizers do their job. Fail here and the compensation pattern moves up to the lumbar spine or down to the knee. There's an edge case I want to mention because it comes up more often than you'd expect. Older adults with lumbar spinal stenosis. The extension-biased exercises like supermans or deep back extensions aggravate their symptoms within minutes. I had a seventy-two-year-old client who couldn't tolerate any prone position. The workaround was to do all core work supine or seated. Seated core work involves isometric holds against resistance in a chair — pressing palms together at chest height and holding, or doing seated Pallof presses with a band anchored to the chair leg. It's less effective than standing work but it's the only option that didn't send her home in pain. For stenosis patients, we prioritize function over form. If they can sit for twenty minutes without bracing, that's a win for stage three equivalency. Another counter-intuitive point: more is not better. Core training two or three times per week is the effective dose. Daily heavy core work disrupts recovery and the deep stabilizers recover slower than superficial muscles because they're type I dominant. Type I fibers need longer rest intervals between sessions. I schedule core work on non-consecutive days for most clients. On off days they get light walking or gentle mobility — nothing that challenges trunk control.
The biggest bottleneck I see is time pressure from insurers and clinic flow targets. A proper six-stage progression for a deconditioned adult takes eight to twelve weeks. Many insurance plans cover six to eight sessions total. That's not enough time to complete all stages with any client who isn't already relatively fit. The workaround is prioritization. For community-dwelling older adults the highest-yield stages are one, four, and five — breath coordination, anti-rotation, and loaded carries. These map directly to ADLs. Planks and dead bugs come later if there's time. For post-stroke clients the sequence changes entirely. Hemiparesis means we start with seated trunk control on the affected side before adding any limb movement. A client who can't lift their trunk against gravity in sitting will never generate core stability in standing. A specific nuance beginners miss: core timing matters more than core force. The transverse abdominis should fire two hundred milliseconds before arm or leg movement. You can test this by having someone reach one arm forward while supine and feeling for TA contraction under your fingers. If the arm moves before the abs contract, the sequence is wrong. This sequencing issue is why some people can do twenty perfect crunches and still injure their back lifting a box. The superficial flexors are strong but they're firing at the wrong time. Our retraining focuses on the sequence first, strength second. If someone has severe central obesity where supine positioning causes breath restriction, skip stages one through three and start at seated core work immediately. If they have a recent lumbar disc herniation with radiculopathy, avoid any flexion-biased exercise for six to eight weeks and focus on neutral-spine stabilization only. These aren't suggestions. They're hard stops.
The exercises above are a framework, not a prescription. Every adult I work with gets a baseline functional assessment first — timed sit-to-stand, trunk control in sitting and standing, single-leg balance duration, and a pain-free range of motion screen. The progression starts where their actual ability is, not where the textbook says it should start. That's the difference between a generic core program and occupational therapy core strengthening. One builds muscle. The other builds the ability to use your trunk while doing the things that matter to you.
