Hamstring Strains

Hamstring Strain Treatment in East London — From Acute Injury to Return to Sport

Book Online

Start Your Recovery

Hamstring strains are the most common muscle injury in sport. They account for an estimated 12–16% of all sports injuries and have the highest recurrence rate of any muscle strain — re-injury rates of 12–34% have been reported in football, with recurrences often more severe than the original injury.

The reason recurrence rates are so high is instructive: hamstring injuries are frequently undertreated. Players return to sport too soon, often after insufficient rehabilitation, without addressing the biomechanical and strength factors that caused the injury. At LPAW, we treat hamstring strains with a structured, evidence-based approach focused on full rehabilitation — not just returning to training when pain has settled.

Anatomy of the Hamstring Group

The hamstrings are a group of three muscles running along the back of the thigh:

Biceps femoris (long and short head): The most commonly injured hamstring muscle. The long head crosses both the hip and knee joints, making it particularly vulnerable during high-speed running.

Semitendinosus

Semimembranosus

All three muscles originate from the ischial tuberosity (the “sitting bone”) and insert below the knee. Their primary functions are knee flexion and hip extension, which are essential for sprinting and jumping.

The hamstrings are particularly vulnerable during high-speed sprinting, especially in the late swing phase of running when they are working eccentrically (lengthening under load). They are also at risk during sudden changes of direction or deceleration.

  • Acute hamstring strain:
  • Sudden sharp pain in the back of the thigh during sprinting, kicking, or explosive movement
  • An audible or felt “pop” in more significant tears
  • Immediate pain with inability to continue activity
  • Bruising appearing 24–48 hours later (particularly in Grade II–III injuries)
  • Tenderness on palpation of the muscle belly or distal tendon
  • Pain and weakness with knee flexion and hip extension
    Proximal hamstring tendinopathy:
  • Deep buttock or high posterior thigh pain, localised around the ischial tuberosity
  • Pain when sitting, especially on hard surfaces
  • Pain with uphill walking or running
  • Gradual onset without a single clear traumatic event
  •  
  • Grade III tear with severe bruising and complete loss of function: Imaging should be considered to assess for a possible proximal avulsion injury.
  • Significant proximal injury in an older athlete: Avulsion injuries are more common with increasing age, and surgical repair may have a limited time window for optimal outcomes.
  • Sciatic-type pain associated with hamstring symptoms: May indicate proximal hamstring involvement with possible sciatic nerve irritation or entrapment.
  • Any significant hamstring injury: Should be assessed promptly, as delayed assessment may miss the early window for optimal management and recovery.

Muscle strain grades:

  • Grade I: Minor strain involving less than 5% of fibres. Mild pain, minimal or no strength loss, and little to no swelling. Walking is usually normal or only slightly affected.
  • Grade II: Partial tear with significant fibre disruption. Moderate to severe pain, antalgic gait, clear tenderness on palpation, possible bruising, and noticeable strength loss.
  • Grade III: Complete or near-complete rupture of the muscle or musculotendinous unit. Severe pain, marked swelling and bruising, and inability to contract the muscle effectively against resistance.

By location:

  • Myotendinous junction strain: Injury at the junction between muscle belly and tendon. This is the most common site of acute hamstring injury and is particularly vulnerable during high-speed movement.
  • Proximal hamstring tendinopathy: Chronic degeneration at the ischial tuberosity attachment. Typically presents as deep buttock pain rather than mid-thigh pain and requires a structured tendinopathy loading programme rather than acute strain management.
  • Proximal hamstring avulsion: Acute traumatic detachment of the hamstring origin from the ischial tuberosity. This is a rare but serious injury that often requires surgical intervention.

How LPAW Treats Hamstring Strains

Acute Management

Acute Management (Days 0–7)

PEACE & LOVE protocol replaces the outdated RICE approach (see Sports Injuries):

  • Relative rest and protection from aggravating activities, including sprinting, stretching, and sustained hamstring loading
  • Elevation and compression to help manage swelling
  • Gentle, pain-free walking should be maintained; complete immobilisation is not recommended
  • Early physiotherapy assessment is important, as the first 48–72 hours are critical for accurate grading and initial management

    What to avoid:
  • Aggressive hamstring stretching in the acute phase, as this can worsen or extend the injury
  • Heat application within the first 48–72 hours
  • Returning to sport based solely on pain resolution, which is a common cause of re-injury

Physiotherapy and sports therapy at LPAW follow a phased rehabilitation framework based on objective criteria rather than time alone:

Phase 1 — Tissue repair (Week 1–2 for Grade I; Week 1–4 for Grade II)

  • Gentle, progressive loading within a comfortable range
  • Low-load isometric hamstring contractions
  • Pain-free functional movement, including normal walking gait and step-ups
  • Swelling management

Phase 2 — Strength foundation (Weeks 2–6)
This is the most important phase for reducing recurrence risk.

  • Nordic hamstring curl: The most evidence-based exercise for both treatment and prevention of hamstring strains. Eccentric loading in a lengthened position directly targets the injury mechanism. A 2015 meta-analysis in the British Journal of Sports Medicine found a 51% reduction in hamstring injury incidence with Nordic training
  • Progressive hip extension strengthening, including Romanian deadlift progressions, hip thrusts, and cable pull-throughs
  • Hip flexor strengthening and mobility work

Phase 3 — Running progression (Weeks 4–8+, depending on grade)

  • Criteria: full pain-free active range of motion, >70% limb symmetry on strength testing, and pain-free controlled running at approximately 70% maximum speed
  • Gradual running programme with progressive increases in speed and distance

Phase 4 — Sport-specific and return to play (Weeks 8–12 for Grade II)

  • Sprinting at full speed, change of direction, and sport-specific movement patterns
  • Return to full training only when objective criteria are met, not based solely on symptom resolution

From the moment I walked into this clinic, I knew everything was going to be okay. After seeing many physios, Priyanka, the pelvic specialist, was the first one to properly diagnose my back injury and choose exercises that were actually right for my condition.

I HIGHLY recommend hydrotherapy. This clinic has truly been life-changing for me. When you live with constant pain, finding real relief is priceless.

Thank you for the care, professionalism, and for giving me hope again ❤️

We had 6 of their amazing physiotherapist support London’s Air Ambulance Charity’s post-race reception for the 2026 London Marathon. Their communication before and during the event was excellent and all our runners have commented on how much their post-race massage has helped them with their recovery. We hope to work with them again in the future

I suffer with lower back disc bulges pinching my muscles and severely limiting my mobility, stability, and indeed causing agonising pain at the worst of times. I received a kind, patient and conscientious home visit at first before being invited to hydrotherapy at the clinic. 2 sessions in and I'm loving it so much, I'm determined to get one of these pools for myself later on in life. Couldn't recommend them highly enough.

I had to visit the clinic for a hip injury I received from running. I started physio with Anup back in November and started with hydrotherapy, moving into physio in the new year. I've had a great experience with Anup and now I'm well on the road to recovery, I've started running again and I know what strength workouts I should be doing to keep up my recovery. So glad I found Anup and the clinic and would recommend them to anyone who has an injury!

I was assisted by Priyanka while recovering from a torn quad, and I couldn’t have asked for a better physiotherapist. She was incredibly supportive during a moment of real vulnerability, and I always felt truly taken care of. Her focus during every session was exceptional she even kept counting my reps to make sure I stayed on track!

Priyanka is a wonderful asset to the team, and I feel very lucky to have had her during my recovery. Highly recommended.

Best Physio ever. I visited the clinic after I damaged the ACL ligament practicing judo. I was unable to walk, using crutches and couldn't bend the leg. I was initially told by the doctor to wait at least 6/7 months to be fully recovered and the physiotherapy was the only way to get better. Thanks to the skilled clinic and very professional physiotherapist, they managed to get me back on trainings after 3/4 months only having now a stronger knee than before. I was assisted my Mohammed N R and his job was beyond the expectations. They have specific equipment to practice a high variety of exercises and furthermore they are super friendly and easy reachable by email or phone for last minute doubts. I cannot thank more for the assistance received for a faster recovery they granted me. I fully recommend them.

Frequently Asked Questions

For Grade I strains, gentle jogging may be appropriate from 7–10 days if pain-free. For Grade II, running at reduced pace from 3–4 weeks; full-speed running from 6–8 weeks if rehabilitation milestones are met. For Grade III, 8–12 weeks before graded running. These are guides — your physiotherapist will assess readiness based on objective criteria, not time alone.
Recurrent hamstring strains almost always indicate that the original injury was inadequately rehabilitated — typically, the athlete returned to sport when pain had resolved but before strength symmetry was restored, and before eccentric loading capacity was built. Adequate secondary prevention requires specifically addressing the deficits that remained after the initial episode. LPAW’s approach targets re-injury prevention as explicitly as acute recovery.
Ice in the first 48–72 hours reduces acute haemorrhage and localised pain. After 72 hours, heat may be more comfortable and helps reduce residual spasm. Neither ice nor heat changes the underlying tissue healing — appropriate loading is the key therapeutic stimulus.
MRI is not routinely required for Grade I hamstring strains. For Grade II injuries, MRI helps confirm grade and location and can inform return-to-sport timelines more precisely. For suspected Grade III tears or proximal avulsion, MRI is recommended to guide management. Your physiotherapist will advise.
No. Proximal hamstring tendinopathy is chronic degeneration at the hamstring origin (ischial tuberosity), characterised by deep buttock pain at the sitting bone rather than mid-thigh pain. It requires a tendinopathy loading approach rather than acute muscle strain management. The two conditions require different treatment programmes.

Recovery

Recovery Timeline
  • Grade I: 1–3 weeks
  • Grade II: 4–8 weeks (often around 6 weeks for return to non-contact training; 8+ weeks for contact sport)
  • Grade III: 8–16 weeks depending on severity
  • Proximal hamstring tendinopathy: 3–6 months
  • First 48 hours: Walk gently, use ice (15 minutes on/off), and avoid aggressive stretching.
  • Avoid pushing through sharp pain: Hamstring strains can significantly worsen if activity continues after injury.
  • Start gentle loading early: From day 2–3, light isometric hamstring contractions (e.g. lying face down and gently pressing the heel into the bed) help stimulate early healing without overloading the tissue.
  • Build posterior chain strength: Recurrent hamstring injuries are often linked to weakness in the hip extensors and posterior chain. Include exercises such as Romanian deadlifts, hip thrusts, and Nordic curls in longer-term training.
  • Do not skip phase 2: The strength phase is where many athletes rush, but this is the stage where most re-injuries are effectively prevented.
