The Achilles tendon has two distinct zones of common pathology, and their treatment differs fundamentally. Mid-portion Achilles tendinopathy responds excellently to eccentric loading — exercises where the calf muscle lengthens under load (heel drops off a step). This is because eccentric loading applies high tensile forces that stimulate collagen synthesis and tendon remodelling in the mid-portion.

Insertional tendinopathy, however, involves the tendon-bone junction and the adjacent retrocalcaneal bursa. Eccentric loading with the heel dropping below the step level actually compresses the insertional enthesis against the calcaneus, aggravating the condition. For insertional tendinopathy, our physiotherapists at Curis 360 Jayanagar and Vasanthapura prescribe isometric loading (calf raises performed only in the neutral or slightly elevated heel position) and avoid any end-range plantarflexion stretching. Getting this distinction correct at the first assessment is the difference between rapid recovery and months of frustrating setbacks.

The counterintuitive first step in Achilles tendinopathy rehabilitation is loading the tendon isometrically — in the very first session. Research by Rio et al. (2015, British Journal of Sports Medicine) demonstrated that a single bout of isometric calf loading (5 sets of 45-second holds at 70% of maximum voluntary contraction) immediately reduces tendon pain for up to 45 minutes via cortical pain inhibition, without any structural stress on the degenerated tissue.

Our physiotherapists at Curis 360 Banashankari and Jayanagar use this isometric protocol (wall sit with calf raises in a fixed position, or leg press machine holds for clinic-based patients) for the first 2–4 weeks to manage daily pain while preparing the tendon for heavier progressive loading. During this phase, we also address the modifiable risk factors: advising on temporary training load reduction (50% reduction in running distance), appropriate footwear modification (heel raise inside the shoe for mid-portion cases), and any biomechanical faults identified in gait analysis.

The Alfredson eccentric heel drop protocol — 3 sets of 15 repetitions on a step, twice daily, for 12 weeks, performed with both a straight knee (gastrocnemius) and a bent knee (soleus) — remains the gold standard for mid-portion Achilles tendinopathy, with the original landmark study reporting 82% success in previously treatment-resistant cases. The protocol must be performed through pain up to 5/10 in severity; complete pain avoidance during exercise is associated with poorer outcomes.

However, the Beyer Heavy Slow Resistance (HSR) protocol — published in the American Journal of Sports Medicine (2015) — demonstrated equivalent outcomes to the Alfredson protocol with significantly better patient adherence (76% vs 52% completion rate). HSR involves 4 sets of 15 repetitions declining to 4 sets of 6 repetitions over 12 weeks, using a leg press and calf raise machine with progressively heavier loads. Our Banashankari and Vasanthapura clinics offer HSR as the preferred protocol for working adults who find the twice-daily Alfredson programme difficult to maintain. For home physiotherapy patients across Bengaluru, we adapt the HSR programme using body weight and resistance bands.

Once a patient can perform a pain-free single-leg calf raise with added body weight load (vest or backpack), they are ready for Phase 3 — Energy Storage and Release exercises. These exercises train the Achilles tendon's spring-like elastic properties, which are critical for running. Exercises include double-leg skipping, single-leg hops, and depth drops (jump off a 20 cm box and immediately rebound). The key principle is minimal ground contact time — the tendon must learn to store and release energy rapidly.

Running return follows a graduated programme: starting with run-walk intervals (1 minute running / 4 minutes walking) and progressing over 6 weeks to continuous 30-minute runs. Our physiotherapists at Curis 360 Jayanagar also perform a detailed running biomechanics analysis — assessing step rate (cadence), ground contact time, heel strike pattern, and hip drop — using slow-motion video analysis. Increasing step rate by 5–10% alone reduces Achilles tendon load by up to 20%, and this single cue can dramatically accelerate running return.

For Achilles tendinopathy cases persisting beyond 3 months despite a compliant loading programme, Extracorporeal Shockwave Therapy (ESWT) is the most evidence-supported adjunct. ESWT has demonstrated significant superiority over placebo in multiple high-quality RCTs for mid-portion tendinopathy. At Curis 360 Banashankari and Jayanagar clinics, we deliver 3 sessions of focused ESWT spaced one week apart, combined with continuation of the HSR programme between sessions.

Platelet-Rich Plasma (PRP) injection, offered by some orthopaedic surgeons, has inconsistent evidence for Achilles tendinopathy and is not recommended as a first-line treatment by current NICE guidelines. Surgical options — including percutaneous tendon tenotomy and open tendon stripping — are reserved for genuine treatment failures after 6 months of optimised physiotherapy and ESWT. The majority of our patients at Curis 360's three Bangalore clinics achieve full recovery without injection or surgical intervention.

Achilles tendinopathy is particularly well-suited to online physiotherapy management because the rehabilitation programme — progressive loading exercises — requires minimal equipment and can be performed anywhere. Our online physiotherapy service for Achilles tendinopathy covers patients across PAN India: from metro cities like Mumbai, Delhi, Chennai, and Hyderabad to smaller cities and towns where specialist tendon rehabilitation is unavailable.

Via video consultation, our physiotherapists assess calf strength (single-leg heel raise testing on camera), tendon sensitivity, and running biomechanics, then prescribe the full phase-matched protocol. We provide detailed video demonstrations of the Alfredson and HSR exercises, monitor loading progression fortnightly, and adjust the programme based on your pain response diary. For Bengaluru patients — particularly in areas like Whitefield, Electronic City, Hennur, and Yelahanka — home physiotherapy visits with portable equipment are also available.
