Post-Sprain Ankle Pain: A Capacity Failure
Patient Profile
- Age/Gender: 23yrs/Male
- Occupation: MBA Student
Chief Complaint:
Pain in the right ankle during loading activities, especially during sports participation.
History:
The patient presented with complaints of right ankle pain that occurs during loading activities such as walking, stair climbing, running, and sports participation.
Three months ago, while playing basketball, he sustained a right ankle inversion sprain, which resulted in severe pain and swelling. He consulted a physician and was advised conservative management with rest and crepe bandage application.
He rested for approximately one month and avoided all physical activity during this period. However, he did not undergo any structured rehabilitation.
After this period of inactivity, he directly resumed sports activities without gradual reloading or functional progression.
Following return to sport, he began experiencing:
- Pain over the anterior aspect of the right ankle
- A feeling of restriction during loading
- Discomfort during running and basketball-specific movements
Initially, he also reported pain around the Achilles region, but later clarified that the primary pain was located at the front of the ankle, rather than the tendon itself.
Over time, due to compensatory overloading of the opposite limb, he began experiencing similar discomfort in the left ankle during sports activity. This led him to completely stop all sports participation.
His primary goal was to be pain-free and return to basketball and cricket.
Past medical/surgical history
Nothing relevant to present complaints, except for the right ankle sprain that occurred 3 months back.
Lifestyle and psychosocial analysis:
Physical activity:
- Markedly reduced due to pain and fear of aggravation.
- Previously active- playing basketball and cricket
- Currently avoiding all sports-related loading activities.
Sleep:
- The patient has no disturbances in sleep and has an average of 8 hours of sleep.
Stress:
- Mild stress related to the inability to participate in sports.
Psychosocial factor analysis
- Cognitive – The patient’s thoughts and beliefs about pain are good
- Affective – Emotionally affected due to inability to participate in sports.
- Social – No major social barriers identified.
Pain Analysis:
Intensity: 6/10
Onset: gradual
Duration: 2 months
Aggravating factor: Walking, Stair climbing, Running, Sports loading
Relieving factor: Rest
Location: the dorsal aspect of the right foot
Lifestyle factor impact: moderate impact. Pain significantly limited participation in recreational sports and reduced overall physical activity levels.
Fear of movement analysis: Present. The patient developed movement-related fear due to pain during loading.
Our understanding of patients' problems:
The patient’s history and pain analysis suggest that he has load-induced anterior ankle pain secondary to incomplete rehabilitation following an ankle sprain.
The likely sequence:
Initial injury → Prolonged rest → Deconditioning → Sudden return to sport → Load intolerance → Compensatory overloading → Bilateral symptoms.
But we need to fully assess the patient to rule out if there is any presence of any serious/ other pathologies.
Physical examination
Observational findings:
Mild swelling over the anterior ankle.
Palpation:
Mild tenderness over the anterior ankle joint line.
Mobility screening:
- Forward bending was good
- Overhead squat- Poor movement quality observed with rotational shift due to limited right ankle dorsiflexion.
ROM analysis:
There is a significant reduction in right ankle ROM(dorsiflexion)
Stability screening:
| Strength Test | Right Side | Left Side | Limb Symmetry Index |
|---|---|---|---|
| Single-leg Squat | 1 rep (painful) | 8 reps | 12% |
| Side Plank (Glutes) | 20 secs | 30 secs | 66% |
| Hamstring Bridge | 4 reps | 8 reps | 50% |
| Calf Raise | 15 reps | 20 reps | 75% |
According to the statistics of the above table, it indicates that the overall strength of the right side lower limb muscles is weak.
Sensory examination:
Intact, there are no sensory disturbances.
Investigation:
X-ray- Normal.
No evidence of:
- Fracture
- Bony abnormality
- Structural instability
Differential diagnosis
1. Achilles tendinopathy
Typically presents with:
- Localised tendon pain
- Pain on tendon palpation
- Morning stiffness
- Pain during tendon loading
- Tendon thickening
Ruled out because:
The patient’s pain is primarily anterior ankle pain without tendon-specific tenderness or classic Achilles loading symptoms.
2. Osteochondral Lesion
Usually presents with:
- Deep ankle pain
- Swelling
- Locking/catching sensation
- Mechanical restriction
Ruled out because:
- No locking or catching symptoms
- X-ray normal
- Clinical presentation is inconsistent with mechanical joint pathology
Possible Diagnosis
Post-Sprain Load Intolerance due to Inadequate Rehabilitation
The patient’s symptoms are most consistent with load-induced anterior ankle pain resulting from incomplete rehabilitation following an ankle sprain.
The lack of progressive loading post-injury resulted in:
- Reduced dorsiflexion mobility
- Strength deficits
- Poor neuromuscular control
- Reduced tissue capacity to tolerate sport-specific demands
The left-sided symptoms likely developed due to compensatory over-reliance.
Treatment Planning:
To restore:
- Pain-free loading capacity
- Ankle mobility
- Lower-limb strength symmetry
- Sport-specific tolerance
- Confident return to basketball and cricket
Overall Treatment Strategy
Duration: 12 Weeks
Estimated Sessions: 25
Session Distribution
- Week 1: 3 sessions
- Weeks 2–5: 12 sessions
- Weeks 6–7: 4 sessions
- Weeks 8–10: 4 sessions
- Weeks 11–12: 2 sessions
Key things to focus on during treatment:
- Reduce Pain Sensitivity: Restore confidence in loading.
- Improve Ankle Mobility: Particularly dorsiflexion range.
- Restore Lower Limb Strength: Targeting limb symmetry.
- Improve Functional Capacity: Progressive cardiovascular and movement conditioning.
- Return to Sport: Graded re-exposure to basketball-specific demands.
Week 1: Foundation Phase
Focus:
- Pain education
- Reassurance
- Building confidence in movement
- Gentle mobility restoration
- Low-load strengthening
Goals:
- Reduce pain sensitivity
- Reintroduce controlled loading
Weeks 2–5: Capacity Building
Focus:
- Progressive strengthening
- Volume and intensity modification
- Cardiovascular reconditioning
Goal:
Restore baseline lower limb load tolerance.
Weeks 6–7: Power Development
Once limb symmetry reaches >80%
Introduce:
- Ballistic loading
- Plyometric drills
- Reactive force development
Goal:
Improve rate of force production.
Weeks 8–10: Multi-Plane Load Exposure
Focus:
- Acceleration/deceleration drills
- Cutting and directional change
- Higher-demand sport-specific loading
Monitor:
- Pain response
- Swelling
- Recovery tolerance
Weeks 11–12: Return-to-Sport Transition
Focus:
- Independent load management
- Recurrence prevention
- Strength and conditioning education
- Progressive return to unrestricted play
Education includes:
- RPE-guided progression
- Load monitoring
- Regression/progression strategies
Clinical Takeaway
- This case highlights an important principle:
Rest alone does not restore function after injury.
Following an ankle sprain, recovery requires graded rehabilitation, progressive loading, and restoration of tissue capacity.
Without this, athletes often develop post-injury load intolerance, movement compensations, and recurrent symptoms despite “healed” tissue.
This patient’s pain was not due to structural damage; it was due to reduced capacity to tolerate load.
