Daily tracker form
The page uses one main content column. The input grid expands to three columns on large screens, two on smaller screens, and one on mobile.
This tool supports self-monitoring and visit preparation. It does not diagnose arthritis type, replace a clinician, or set medication decisions.
Formula used
1) Average pain
Average Pain = (Morning Pain + Afternoon Pain + Evening Pain) / 3
2) Standardized component scores
Pain Load = Average Pain × 10
Stiffness Score = (Morning Stiffness ÷ 180) × 100
Swelling Score = Swelling Level × 10
Fatigue Score = Fatigue Level × 10
Sleep Penalty = 0 when sleep is 8 hours or more; otherwise ((8 − Sleep Hours) ÷ 8) × 100
Activity Penalty = 0 when activity is 45 minutes or more; otherwise ((45 − Activity Minutes) ÷ 45) × 100
Tender Score = (Tender Joint Count ÷ 28) × 100
Flare Days Score = (Flare Days ÷ 7) × 100
Adherence Penalty = 100 − Medication Adherence
Mood Score = Mood Impact × 10
3) Symptom burden score
Symptom Burden = 0.28×Pain + 0.14×Stiffness + 0.10×Swelling + 0.10×Fatigue + 0.10×Tender + 0.10×Flare Days + 0.06×Sleep Penalty + 0.05×Activity Penalty + 0.04×Adherence Penalty + 0.03×Mood
4) Function comfort score
Function Comfort = 100 − (0.45×Stiffness + 0.20×Activity Penalty + 0.15×Fatigue + 0.10×Sleep Penalty + 0.10×Mood)
5) Flare risk score
Flare Risk = 0.35×Pain + 0.20×Swelling + 0.15×Tender + 0.15×Flare Days + 0.10×Stiffness + 0.05×Mood
Higher burden and flare scores suggest heavier symptom activity. Higher function comfort and self-management scores suggest better daily coping and routine stability.
How to use this calculator
- Enter the date, age, and the joint region you want to track.
- Record pain for morning, afternoon, and evening on a 0 to 10 scale.
- Add stiffness time, swelling, fatigue, sleep, activity, tender joints, and flare days.
- Enter medication adherence and mood impact to capture daily self-management context.
- Mark likely triggers and add notes for weather, stress, workload, or routine changes.
- Press the calculate button to show the score cards and graphs above the form.
- Use the CSV and PDF buttons to save entries for your own records or appointments.
- Compare repeated daily logs over time to spot consistent triggers and flare patterns.
Example data table
| Date | Joint Region | Morning Pain | Afternoon Pain | Evening Pain | Stiffness | Swelling | Fatigue | Sleep | Activity | Flare Days | Burden Score |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 2026-03-20 | Multiple joints | 6 | 5 | 7 | 55 min | 5 | 6 | 6.0 h | 20 min | 3 | 56.8 |
| 2026-03-21 | Knees | 4 | 3 | 5 | 30 min | 3 | 4 | 7.2 h | 35 min | 1 | 34.6 |
| 2026-03-22 | Hands and wrists | 7 | 6 | 8 | 75 min | 6 | 7 | 5.5 h | 15 min | 4 | 67.9 |
The example values show how changing sleep, activity, stiffness, and flare days can shift the burden score.
FAQs
1) What does the symptom burden score mean?
It combines pain, stiffness, swelling, fatigue, flare frequency, sleep, activity, adherence, and mood into one 0 to 100 tracking score. Higher values indicate heavier symptom burden for that entry.
2) Is this calculator a medical diagnosis tool?
No. It is a structured tracker for self-monitoring and discussion support. It cannot confirm rheumatoid arthritis, osteoarthritis, gout, or any other condition.
3) Why are there three pain fields?
Morning, afternoon, and evening scores help capture daily variation. Many people feel worse after waking, after work, or at night, so a single value can miss useful patterns.
4) How often should I record entries?
Daily entries are best during medication changes, recovery periods, or flare-prone weeks. During stable periods, logging several times per week can still reveal meaningful trends.
5) What is flare risk measuring here?
It estimates flare likelihood from pain load, swelling, tender joints, stiffness, mood impact, and recent flare days. It is a tracking indicator, not a prediction guarantee.
6) Why does sleep affect the score?
Poor sleep can worsen pain perception, fatigue, concentration, and recovery. The tracker adds a sleep penalty when hours fall below eight to reflect that daily influence.
7) Can I bring these reports to appointments?
Yes. Exported summaries can help you discuss timing, triggers, functional limits, and whether symptoms improved or worsened after treatment or routine changes.
8) Which score should I watch most closely?
Watch the burden score for overall symptom load, flare risk for short-term worsening, and function comfort for daily ability. Trends across several entries matter more than one isolated number.
