Assessment
Your physiotherapist discusses your symptoms, goals, medical history and lifestyle, then completes a thorough assessment. Initial appointments are typically 45 to 60 minutes, so there is time to do it properly.
A half-rehabbed muscle is a muscle that tears again: most hamstring re-injuries happen in the first month back because strength was never rebuilt and never tested. Muscle injury treatment in London and Henley for hamstring strains, calf tears, quadriceps and adductor injuries, with graded loading and structured return-to-sport testing so the next sprint is not the one that sends you back to square one.
Overview
Muscle strains and tears are the most common acute injury in running, football, rugby and field sport. Hamstring strains alone account for a large share of time lost in elite football, and in amateurs recurrence rates run as high as 63 % when return-to-sport criteria are skipped. A half-rehabbed muscle is a muscle that tears again.
Recovery is staged, and the loading is the part that actually rebuilds the tissue:
Grades guide the timeline: most Grade 1 strains clear in 2 to 3 weeks and Grade 2 in 4 to 8 weeks, while a Grade 3 full rupture usually needs a surgical opinion before rehab proceeds. Every plan is filmed through Track Rehab so the loading is repeatable between sessions.
Physiotherapy leads the rehab. Soft tissue therapy helps with chronic tension and fibrotic scarring within the muscle belly, and for a stubborn adductor or proximal hamstring tendinopathy shockwave therapy can accelerate the response. Muscular injuries sit within our wider sports injury care, and recurring running strains often warrant a running gait analysis to find the driver.

I first started using Tom last year to help relieve back pain, he has been extremely helpful and now he's supporting me with sprint and fitness training, whilst helping with any minor injuries. Can't recommend him and his team more highly.
I went to Tom with a shoulder injury that had not improved for several months. Tom is very knowledgeable and quickly identified the issue and put me on a course of exercises that, in conjunction with a couple more sessions, steadily resolved the problem. I would highly recommend him.
Parinita was brilliant! Identified my knee problem immediately, used a range of equipment and exercises not only to strengthen my knee, but to maintain it and improve my running long-term.
Excellent service! Sanchez is a true professional who helped me heal a previous injury. Highly recommend!
Grade 1 strains keep full strength and settle in 2 to 3 weeks. Grade 2 brings bruising and weakness and needs 4 to 8. A suspected Grade 3 rupture needs same-week imaging and a surgical opinion. Getting the grade right on day one shapes everything that follows.
Ice and compression help for the first 24 to 48 hours; beyond that, gentle range-of-motion and very early loading do the healing. Prolonged rest lets the muscle waste while the injury scars. We start the loading work within the first week wherever the tissue allows.
Hamstrings re-tear when rehab stops at pain-free jogging. The middle stage here is progressive eccentric loading, including Nordic hamstring variants, worked through the full range that sprinting and kicking demand rather than the range that feels comfortable in the clinic.
Recurrence in amateurs runs as high as 63 percent when return-to-sport criteria are skipped. Clearance here means limb-strength symmetry of at least 90 percent, full range of motion, and sport-specific drills under fatigue. The benchmarks are measured, agreed with you and retested before release.
Poor hip extension, hip drop and trunk lean overload the hamstring at exactly the point in the stride where it is most vulnerable. We assess sprint mechanics as part of rehab, and for runners a sensor-based gait review identifies the movement fault driving the repeat strains.
Chronic tension and fibrotic scarring within the muscle belly can hold a strain back mid-rehab. Soft-tissue therapy supports the loading plan in these cases, and for a stubborn adductor or proximal hamstring tendinopathy, shockwave therapy accelerates the response when loading alone has stalled.
Why it happens
Sudden mechanical overload at high muscle length under tension (sprint, change of direction, kicking)
Cumulative overload: training-volume spike or fatigue at the end of training/match
Strength deficits in the affected muscle group (especially eccentric strength of hamstring)
Movement-pattern faults: poor sprint mechanics, hip drop, trunk lean
Inadequate warm-up or rapid temperature drop during play
Previous muscle injury without full rehab clearance: strongest predictor of recurrence
Initial appointments are typically 45 to 60 minutes. You leave with a clear explanation of your condition, treatment recommendations, a report explaining it in simple language, and a personalised rehabilitation plan.
Follow-ups run 30 to 45 minutes, and we reassess at every visit rather than selling you a block of sessions up front.
A thorough, honest, and understandable explanation. Then the best treatment to get you back to a level of activity beyond your pre-injury status. If we can't get you better, we will recommend the world's leading healthcare professionals in London that can.

A clear explanation of your condition and a report explaining it in simple language, alongside hands-on treatment: manual therapy, soft tissue techniques and joint mobilisation where they help.
Exercise rehabilitation tailored to your goals and condition, delivered through Track Rehab. Our clinics sit inside gym facilities, so the plan has the equipment and technology it actually needs.
Structured programmes and return-to-sport testing before you go back, so you return safely and confidently. The goal is a level of activity beyond your pre-injury status, not just less pain.
Treatment approach
Staged loading rehab is the core treatment for muscle injury: protect-load early, progressive eccentric mid, sport-specific late. Most Grade 1 strains clear in 2 to 3 weeks; Grade 2 in 4 to 8 weeks.
See treatment detail →Useful for chronic muscle tension, fibrotic scarring within the muscle belly, and adjunct support during the mid-rehab phase. Not a stand-alone treatment for an acute strain.
See treatment detail →For chronic adductor or proximal hamstring tendinopathy that has not responded to loading alone, ESWT accelerates the response when added to the rehab plan.

Three rough buckets. Grade 1 (mild): localised tenderness, full strength, full range of motion, ability to walk normally. Grade 2 (moderate): visible bruising within 24 to 72 hours, weakness on testing, gait limp. Grade 3 (severe/rupture): immediate sharp pain with a 'pop', visible defect or muscle bunching, severe loss of function, often unable to weight-bear. Grade 3 needs same-week imaging and surgical opinion; Grade 1 and 2 are routine physiotherapy cases.
Only after structured return-to-sport testing: limb-strength symmetry of at least 90 %, full range of motion, sport-specific drills under fatigue, and psychological readiness. Skipping these stages is the strongest predictor of re-injury (more than 50 % of recurrent hamstring injuries happen within the first month post-return when criteria are skipped). We test against measurable benchmarks rather than discharging on "feels OK".
For the first 24 to 48 hours, ice + compression + relative rest helps with pain and swelling. Beyond that the evidence for icing is weak, and for some tissue (tendon-dominant injury) prolonged ice may slow healing. Move to gentle range-of-motion and very early loading work as soon as the acute pain settles, usually within the first week. We will guide the timing at your first appointment.
Three reasons: athletes return to sport before strength has actually rebuilt, eccentric strength is rarely tested before clearance, and underlying movement-pattern drivers (sprint mechanics, hip drop) are not always addressed. Modern rehab: Nordic hamstring exercise variants, eccentric loading throughout range, biomechanical assessment of sprint mechanics: has cut elite recurrence rates substantially. We use the same approach for amateurs.
