What the apps do
Tennis Elbow Oracle (lateral epicondylitis) and Golf Elbow Oracle (medial epicondylitis) are daily home exercise apps designed around heavy slow resistance (HSR) loading — the most evidence-supported conservative intervention for chronic tendinopathy. The apps guide patients through a structured daily session with a built-in eccentric metronome, morning symptom calibration, and staged progression across a 12–16 week programme.
Both apps are free to download. They are not medical devices. They do not diagnose, treat, cure, or prevent any disease. They are educational and self-management tools, recommended for patients who have already been assessed and given a working diagnosis of lateral or medial epicondylitis by a qualified clinician.
The protocol
The rehabilitation protocol implemented in both Oracle apps is consistent with current best-evidence guidelines for tendinopathy management. Core elements:
- Heavy slow resistance (HSR) training — the primary loading modality, based on Kongsgaard et al. (2009) showing equivalence to surgery and superiority to corticosteroid at 12 months for patellar tendinopathy, applied to elbow tendinopathy via the Cook & Purdam continuum model.
- Eccentric tempo guidance — each repetition is paced with an audio metronome (3–4 seconds eccentric, 2 seconds concentric). Correct tempo is critical to the therapeutic mechanism; the app enforces it without requiring patient knowledge of exercise science.
- Daily morning calibration — a traffic-light symptom rating (green/amber/red) at the start of each session auto-adjusts that day's load and rest periods, implementing the reactive/adaptive tendinopathy management principle without requiring patient decision-making.
- Staged progression — Tennis Elbow Oracle frames the 12–16 week programme as a 5-Set tournament (Acute → Stabilisation → Build → Maintenance → Sport-Proofing). Golf Elbow Oracle uses a 9-Hole progression. Progression gates prevent patients from advancing prematurely.
- Equipment agnostic — the protocol auto-swaps exercises when equipment changes (barbell → dumbbell → resistance band → kettlebell), with load recalculation. Patients can complete the programme with household items.

What physiotherapists can expect
If you recommend the Oracle apps to patients, here is what they will experience and what you can review at follow-up:
- Daily 10–20 minute sessions — the app guides patients through the full session including warm-up, loading sets, and cool-down. No prior exercise knowledge is needed.
- Symptom trend data — the morning traffic-light calibration is logged every day. Patients see a rolling chart of their symptom trajectory. You can review this trend to assess response to loading.
- Load progression log — every session records which exercises were completed, at what load and tempo, and whether the set was rated successful. This gives you objective adherence data rather than patient recall.
- PDF export — patients can generate and share a structured progress report covering calibration history, session completion, and load progression. The PDF is shareable via email or messaging from within the app.
- No account, no subscription for core features — patients do not need to create an account or pay anything to complete the full 12–16 week programme. A premium subscription unlocks additional features (extended tracking, export history) but is not required for the core rehabilitation protocol.
Appropriate patient selection
The Oracle apps are most appropriate for patients who have:
- A working diagnosis of lateral epicondylitis (Tennis Elbow Oracle) or medial epicondylitis (Golf Elbow Oracle) from a qualified clinician
- No significant neurovascular symptoms, cervical radiculopathy, or bony pathology on imaging
- Symptom duration of more than 4 weeks (the protocol is not appropriate for acute tendon tears)
- Adequate hand grip to perform resisted wrist extension or flexion loading
- Access to a smartphone (Android or iOS) and at least one resistance modality (dumbbells, band, or kettlebell)
The apps are not appropriate as a primary intervention for patients with acute trauma, suspected radiculopathy, recent corticosteroid injection (within 6 weeks), or significant diagnostic uncertainty. In these cases, clinical assessment should precede any structured loading programme.
Frequently asked questions
- What rehab protocol do the Oracle apps follow?
- Both Tennis Elbow Oracle and Golf Elbow Oracle implement a daily heavy slow resistance (HSR) protocol with strict eccentric tempo, consistent with the Kongsgaard et al. (2009) methodology and Cook & Purdam continuum model. Patients complete a morning symptom calibration that adjusts load automatically. Progression is structured over 12–16 weeks with clear stage gates. No gym is required — the protocol adapts to dumbbells, resistance bands, or kettlebells.
- Can patients use the app without seeing a physiotherapist?
- Yes — the apps are designed as standalone self-management tools for patients with a confirmed lateral or medial epicondylitis diagnosis. They are educational tools, not medical devices. Patients with significant neurovascular symptoms, recent trauma, or diagnostic uncertainty should always see a qualified clinician first. The apps are most effective alongside professional guidance but function independently for patients who have been assessed.
- How does the morning calibration work?
- Each morning, the patient rates their elbow stiffness on a traffic-light scale: green (proceed at full load), amber (reduce load by one level), or red (isometric-only or rest). The calibration happens before the session starts and automatically adjusts the day's programme. Daily ratings are logged and shown as a trend chart — useful for clinical review at follow-up appointments.
- Can I share progress reports with patients or colleagues?
- Yes. Both apps include a PDF export showing daily calibration ratings, completed sessions, load progression over time, and missed sessions. The PDF can be shared via email or messaging directly from within the app. This makes it straightforward to review home exercise compliance and load history at your next consultation.
