Achilles tendinopathy is a common and often frustrating condition that affects the Achilles tendon, the thick band of tissue that connects your calf muscles to your heel bone. This tendon is essential for walking, running, and jumping, making any pain or dysfunction here a significant barrier to daily activities and sport.
In this blog, we’ll break down what Achilles tendinopathy is, what causes it, the symptoms to look out for, and most importantly, how physiotherapy can help you get back on your feet – literally.
Achilles tendinopathy affects both athletic and non-athletic populations but is especially prevalent in runners and individuals who engage in sports involving repetitive jumping or sprinting (e.g. basketball, tennis, football). It is estimated to affect between 6–18% of runners, and its incidence increases with age, particularly in those over 30.
Key contributing factors include:
- Sudden increases in training volume or intensity
- Poor biomechanics (e.g. overpronation, leg length discrepancy)
- Inadequate footwear or changes in footwear
- Calf muscle weakness or tightness
- Poor tendon loading history
- Systemic conditions like diabetes or high cholesterol
Understanding the tendon: The three types of tendinopathy
Tendinopathy is an umbrella term used to describe tendon pain and dysfunction. There are three stages that a tendon can progress through:
- Reactive Tendinopathy
- Usually occurs after a sudden increase in load (e.g. a new running programme).
- Tendon becomes swollen and painful but may not be structurally damaged.
- This stage is reversible with appropriate load management.
- Tendon Disrepair
- The tendon structure begins to show signs of breakdown.
- Collagen fibres become disorganised, and the tendon may thicken.
- Pain may persist longer, and capacity to tolerate load diminishes.
- Degenerative Tendinopathy
- Common in older adults or those with a long-standing issue.
- Tendon shows areas of cell death and disorganisation.
- There’s an increased risk of rupture.
- Requires longer-term rehabilitation but still responds well to treatment.
Symptoms of Achilles tendinopathy
- Gradual onset of pain in the back of the heel or lower calf
- Morning stiffness or pain with the first few steps of the day
- Pain that worsens with activity, especially running or jumping
- Thickening or nodules in the tendon
- Tenderness when pinching the tendon
- Reduced calf strength or endurance
Functional restrictions
Achilles tendinopathy can significantly limit your:
- Walking (especially uphill or upstairs)
- Running and sports participation
- Ability to push off the ground (e.g. during jumping or sprinting)
- Daily routines involving prolonged standing or barefoot walking
How Physio can help
Physiotherapy is highly effective in treating Achilles tendinopathy. Our approach is evidence-based and tailored to the individual. Here’s what we focus on:
- Accurate Assessment
- We begin with a thorough assessment to determine the stage of your tendinopathy and any underlying contributing factors, such as biomechanics or load errors.
- Load Management
- In the early stages, we may need to reduce or modify aggravating activities (e.g. high-impact sport) while maintaining some level of safe activity to avoid complete deconditioning.
- Progressive Loading Program
- The gold standard for tendinopathy rehab is progressive loading through specific strength-based exercises:
- Isometric exercises for pain relief (early stage)
- Slow, heavy resistance training (mid-stage)
- Plyometrics and sport-specific drills (late-stage)
- This helps rebuild tendon capacity and reduce symptoms.
- The gold standard for tendinopathy rehab is progressive loading through specific strength-based exercises:
- Manual Therapy and Adjuncts
- While exercise is the cornerstone, other techniques may complement your recovery:
- Soft tissue massage or dry needling (for surrounding tightness)
- Taping or heel lifts (to offload the tendon in acute stages)
- While exercise is the cornerstone, other techniques may complement your recovery:
- Education
- We guide you on appropriate activity modification, footwear, and realistic timeframes – empowering you to manage your recovery confidently.
Recovery Timeframes
Recovery is not instant – tendons respond slowly to load due to their limited blood supply. A general guide:
- Reactive tendinopathy: 4-8 weeks with early intervention
- Tendon disrepair: 8-12 weeks
- Degenerative tendinopathy: 3-6 months or more depending on severity
Consistency with rehab is key, and improvement is often gradual. However, most people experience significant relief and return to sport or activity when following a structured programme.
Achilles tendinopathy can be stubborn, but with the right assessment, education, and progressive rehab, it does get better. If you’re struggling with pain in your Achilles or calf, don’t wait – early intervention leads to quicker and more complete recovery. Book an appointment online.
