Occupational Performance Intervention Protocol
Visual Efficiency Through Movement
Building oculomotor and binocular endurance on a stable postural base, then transferring it into near-point school work.
1 — Introduction
What this protocol is for
This protocol is for the student who can see the print but cannot sustain the work: place-loss, re-reading, headaches after ten minutes, copying that starts accurate and ends scrambled.
The organizing idea is that eye movement is a postural act. Saccades, pursuits, and convergence are performed by a body that must first be stable enough to hold the head quiet. When trunk and head control cost too much attention, visual efficiency degrades long before the visual system itself is the problem.
So the sequence moves outward: stabilize the base, dissociate eyes from head, load the eyes dynamically, then convert the gain into a near-point occupational task. Nothing here replaces an eye care referral — it addresses documented efficiency demands within occupational therapy scope.
2 — Clinical reasoning
Why this sequence, for this student
Reading, copying, and sustained near work break down over time rather than at the first attempt. Performance is adequate briefly and degrades with duration.
Likely limiting factors
Level 2: Visual Efficiency
Saccadic accuracy, pursuit smoothness, and convergence endurance are the direct contributors to place-loss and re-reading.
Level 4: Visual-Motor Integration
Eye–head dissociation and postural control determine whether the eyes can work independently of the body.
Level 5: Functional Integration
The complaint is duration-based: the student holds up, then does not. That is a capacity problem across the school day.
Before you start
- Visual access is addressed or documented: acuity, contrast, and print size are not the limiting variable.
- Postural base can be graded — the student can hold a supported upright position long enough to begin.
- Any diagnosed binocular or accommodative condition is under eye care management; this protocol supports it, never substitutes for it.
Stop, grade down, or refer
- New or changing symptoms — diplopia, sudden headache pattern change, decline in acuity — are a referral, not a treatment target.
- Autonomic signs during movement (pallor, nausea, sweating) stop the session; grade down and reconsider vestibular loading.
- Seizure history or medical movement restrictions require clearance before the dynamic stages.
3 — Recommended intervention sequence
Preparation → Occupational Performance Activity → Interactive → Printable → Carryover. The order is the reasoning: stabilize, load in movement, control the variables, transfer to the occupation, distribute the dose.
Preparation
5 minSet the postural platform. Proximal stability is what lets the eyes move without the head and trunk moving with them.
Watch for
- Trunk sway or hand support appearing within the first minute.
- Head fixing forward as a substitute for core control.
- Breath-holding, which usually means the position is one grade too hard.

Occupational Performance Activity
10–12 minDissociate eyes from head and load balance and gaze together. This is where the efficiency demand is built in a whole-body context the student tolerates.
Watch for
- Head turning to accomplish what the eyes should do — the core error this stage targets.
- Loss of target when the base becomes unstable; that ordering tells you which system fails first.
- Fatigue point in minutes, not repetitions — record it.

Interactive
8–10 minMove the same demand to a screen-controlled, gradable target where speed and accuracy can be held constant and observed.
Watch for
- Accuracy holding while speed rises, versus speed rising at the cost of accuracy.
- Symptom report at the two-minute and six-minute mark.

Printable
8–10 minTransfer to paper at the actual occupational demand — text-like arrays, tracking, and near-point scanning that resemble classroom work.
Watch for
- Whether gains from the dynamic stages survive the shift to static near work.
- Line-loss frequency; this is the measure that maps directly to reading complaints.

Carryover
5 min dailyDistribute the dose. Efficiency responds to short, frequent loading far better than to one long weekly session.
Watch for
- Whether the teacher and family can actually run it — if not, simplify rather than insist.
- Duration tolerated at home, which is your between-session data.

4 — Grading
Progressions and regressions
Postural base
Progress
- Supported sitting → unsupported sitting → tall kneeling → half kneel → standing → unstable surface.
- Add an upper-extremity load only after the position is quiet for 60 seconds.
Regress
- Return to back support or wall support.
- Shorten the hold and increase the number of holds.
Eye–head demand
Progress
- Head still with eyes moving → head moving with eyes fixed → both moving in opposition.
- Small excursion → full field excursion → excursion beyond comfortable range.
Regress
- Return to a stationary head with a large, high-contrast target.
- Reduce excursion to within 15 degrees of midline.
Target and speed
Progress
- Large high-contrast target → smaller target → letter or word target.
- Self-paced → therapist-paced → metronome or timed pacing.
Regress
- Increase target size and contrast before slowing pace; size first, then speed.
Cognitive load
Progress
- Single task → naming or counting while tracking → tracking while answering content questions.
Regress
- Strip the second task entirely; dual-task failure means the primary skill is not yet automatic.
FITT-P dosage
- Frequency: 2 sessions per week direct, 5 short carryover bouts per week.
- Intensity: work at a level where accuracy stays above roughly 80% — accuracy first, then speed.
- Time: 30–40 minutes direct; 5 minutes carryover.
- Type: postural preparation → movement-based eye–head work → gradable interactive → near-point paper task.
- Progression: advance one variable at a time — base, excursion, speed, or cognitive load. Never two at once.

Session record and progress measures
Use this one-page session map as the running record. It captures the two things that actually drive decisions: where in the sequence performance broke down, and how long the student sustained before it did.
Visual Efficiency Through Movement — session record
Session date / number
Track against the 6–8 week reassessment window.
Postural level used
Supported sit, unsupported sit, tall kneel, half kneel, stand, unstable surface.
OPA activity + grade
Which activity, at which excursion and speed.
Minutes to first breakdown
Place-loss, head substitution, symptom report — whichever came first.
Interactive accuracy / speed
Percent accurate and pace setting.
Near-point transfer
Did the printable task hold the gain? Line-losses per trial.
Symptom report
None / mild / stopped session. Note anything new — new is a referral trigger.
Carryover assigned
What went home or to the classroom, and who is running it.
Next-session change
The single variable you will advance or regress.
Progress measures
- Minutes of sustained near work before place-loss or complaint (primary occupational measure).
- Line-losses per 100 words of oral reading, or per copying trial.
- Postural level achieved while maintaining target accuracy.
- Teacher rating of independent near-work participation.
Reassessment
Re-screen the limiting level after 6–8 weeks of consistent dosage. If the occupational measure has improved, fade the protocol and hold the carryover pieces. If the contributing level improved but the occupation did not, the limiting factor was elsewhere — return to the pathway and re-reason. If neither moved, or symptoms are new or worsening, refer rather than continue.
