- Gait Analysis: Observing walking and running patterns to identify abnormal biomechanics (e.g., overpronation, excessive supination, poor propulsion) that contribute to heel loading.
- Foot Posture Assessment: Static and dynamic evaluation of arch height, hindfoot alignment (e.g., calcaneal valgus/varus).
- Muscle Length/Flexibility: Assessing tightness in the calf muscles (gastrocnemius and soleus), Achilles tendon, and hamstrings, which can increase strain on the plantar fascia.
- Muscle Strength: Evaluating strength of intrinsic foot muscles, ankle dorsiflexors/plantarflexors, and hip musculature (e.g., glutes) as weakness proximally can affect foot mechanics.
- Joint Mobility: Assessing mobility of the ankle, subtalar, and midfoot joints.
- Palpation: Precisely identifying tender points (e.g., plantar fascia origin, fat pad, bursa, nerve pathways).
- Differential Diagnosis: Ruling out other conditions (e.g., stress fracture, nerve entrapment, referred pain) through specific tests.
Pain Management and Inflammation Control:
- Activity Modification: Educating on reducing aggravating activities and modifying training loads.
- Cryotherapy: Ice application to reduce inflammation and pain.
- Taping (Kinesio Taping): To provide immediate support to the arch, reduce tension on the plantar fascia, and offer pain relief.
- Dry Needling: Can be highly effective in releasing trigger points in the calf muscles or intrinsic foot muscles that refer pain to the heel.
- Electrotherapy Modalities: Therapeutic ultrasound, interferential current (IFC), or TENS for pain relief and tissue healing.
- Shockwave Therapy : A non-invasive treatment that delivers high-energy sound waves to the affected area, promoting tissue healing and reducing pain.
Manual Therapy Techniques:
- Soft Tissue Mobilization: Deep tissue massage, myofascial release, or instrument-assisted soft tissue mobilization (IASTM) to release tension in the plantar fascia, calf muscles, and other restrictive tissues.
- Joint Mobilizations: To improve mobility in the ankle, subtalar joint, and midfoot joints, especially if stiffness is present. This helps optimize foot mechanics.
- Neural Mobilization (Nerve Glides): If nerve entrapment (e.g., Tarsal Tunnel Syndrome, Baxter’s nerve entrapment) is suspected, gentle nerve gliding exercises can help free the nerve and reduce irritation.
Therapeutic Exercise Program:
- Plantar Fascia Specific Stretching:
- Wall/Step Calf Stretches: Focusing on both gastrocnemius (knee straight) and soleus (knee bent) to ensure comprehensive calf flexibility.
- Plantar Fascia Stretch: Pulling toes back towards the shin, creating tension in the arch.
- Night Splints: Wearing a splint overnight to keep the ankle dorsiflexed and the plantar fascia on a sustained stretch, preventing morning pain and promoting healing.
Intrinsic Foot Muscle Strengthening :
- Short Foot Exercise: Actively lifting the arch without curling the toes.
- Towel Curls: Using toes to scrunch up a towel.
- Marble Pick-ups: Picking up small objects with toes.
Calf Strengthening (Eccentric Focus):
- Heel Raises (especially eccentric): Standing on both feet, rising onto toes, then slowly lowering the heel on the affected side only. This builds resilience in the Achilles tendon and calf muscles.
Lower Limb Strength and Stability:
- Hip and Gluteal Strengthening: Exercises like clam shells, side leg raises, glute bridges, and single-leg squats to improve hip control and align the entire kinetic chain.
- Balance and Proprioception: Single-leg standing, wobble board exercises, or balance beam work to improve ankle and foot stability.
Advanced Rehabilitation for Athletes/High-Impact Individuals:
- Plyometric Drills: Gradually incorporating jumping and hopping exercises to improve shock absorption and load tolerance.
- Sport-Specific Drills: Exercises to the demands of the patient’s specific sport or activity.
- Running Analysis: For runners, detailed analysis and correction of running form to reduce impact and stress on the heels.
