Overview
Groin strains encompass a spectrum of adductor muscle and tendon injuries at the medial thigh, most commonly affecting the adductor longus at its proximal musculotendinous junction. They are the second most common acute muscle injury in football globally and a major source of morbidity in Indian cricket, kabaddi, and hockey — sports that demand explosive change of direction, kicking, and split-step lunging actions. Groin injuries have a notoriously high chronicity rate: up to 50% of acute groin strains become chronic groin pain (athletic pubalgia) if not fully rehabilitated, requiring months of management and occasionally surgical consultation. The groin region presents one of physiotherapy's most complex differential diagnoses — the same area of pain can arise from the adductors, hip flexors (iliopsoas), pubic symphysis, obturator nerve, or even referred pain from the lumbar spine — and distinguishing between these is critical to prescribing effective treatment. At Curis 360 Physiotherapy's Banashankari, Jayanagar, and Vasanthapura clinics, Dr. Ponkhi Sharma PT uses a structured clinical examination and — where indicated — ultrasound or MRI correlation to diagnose and phase groin injuries precisely.
Common Symptoms
- Sharp, localised pain at the inner thigh/groin at the time of injury — typically with a kick, side-step, or sprint.
- Tenderness on palpation of the adductor longus tendon at its proximal attachment on the pubic bone.
- Pain and weakness on resisted hip adduction testing (squeezing the inner thighs against resistance).
- Stiffness and groin ache the morning after sporting activity.
- Reduced hip adduction and abduction range of motion.
- Pain on the squeeze test (lying on back, squeezing a ball between the knees at 90° hip and knee flexion).
- In chronic cases: bilateral groin pain during and after sport, pain with coughing or sit-ups (suggesting pubic symphysis involvement).
Primary Causes
- Explosive hip abduction or rotation during kicking, lunging, or side-stepping that exceeds adductor tensile capacity.
- Adductor strength deficit — the primary modifiable risk factor; adductor-to-abductor ratio below 0.8 significantly increases injury risk.
- Previous groin strain — substantially increases re-injury risk if not fully rehabilitated.
- Hip mobility restriction — limited hip internal rotation increases adductor compensatory load.
- Inadequate pre-season conditioning — the majority of cricket and football groin strains occur in the first 4 weeks of a new season.
- Repetitive overuse — in cricket fast bowlers and hockey midfielders, chronic pubic symphysis stress from repetitive pelvic loading.
- Weak core and gluteal muscles — poor lumbopelvic stability increases adductor load during rapid directional changes.
1. Diagnosing Groin Pain — Beyond the Adductor
Groin pain in an athlete is one of physiotherapy's most complex diagnostic challenges. The Doha Agreement Meeting classification (2015) identified 11 distinct groin pain entities in athletes, divided into four defined syndromes (adductor-related, iliopsoas-related, inguinal-related, and pubic-related) plus hip joint pathology. Misdiagnosis — typically treating an iliopsoas strain as an adductor problem, or vice versa — leads to prolonged recovery and chronicity.
At Curis 360 Banashankari and Jayanagar clinics, our assessment uses the full Doha battery: the squeeze test at 0°, 45°, and 90° hip flexion; the single adductor test; the bilateral adductor test; the bent-knee fall-out test; the FABER and FADIR tests (hip joint); and a palpation map of the pubic tubercle, adductor longus, rectus abdominis insertion, and inguinal ligament. Inguinal hernias and sports hernias (athletic pubalgia) must be excluded by our clinical examination, with ultrasound or surgical referral if suspected.
2. Phase 1 — Acute Management & Isometric Loading
Acute groin strain management at Curis 360 begins with 24–48 hours of POLICE (Protection, Optimal Loading, Ice, Compression, Elevation). Ice packs applied to the inner thigh for 15 minutes every 2–3 hours, with a compressive support bandage. Crutch-assisted walking is used only for Grade II–III injuries where weight-bearing reproduces significant groin pain.
Isometric adductor loading begins on Day 2–3: the patient lies supine with the knees slightly bent, squeezing a ball or cushion between the knees at a level producing 3–4/10 pain for 5 sets of 10-second holds. This isometric protocol is based on Rio et al. cortical pain inhibition evidence and immediately reduces tendon pain while beginning collagen stimulation. From Day 5–7, we progress to side-lying hip adduction exercises with the lower leg raised, and shallow bilateral standing adductor squeezes against a wall.
3. Phase 2 — Copenhagen Adductor Programme
The Copenhagen Adductor Exercise (CAE) — derived from the Copenhagen Groin Injury Prevention study — has the highest evidence base of any adductor strengthening exercise. In the CAE, the patient lies on their side with the top foot resting on a bench; they lift their bottom leg up to touch the bench (hip adduction with body weight load). A 2019 British Journal of Sports Medicine RCT (Harøy et al.) demonstrated that a 10-week CAE programme reduced groin injury incidence by 41% in elite football — the largest documented preventive effect of any single exercise in sport.
At Curis 360 Jayanagar and Vasanthapura clinics, we implement the CAE programme starting with the easier 'short lever' version (knees bent) and progressing to the 'long lever' version (straight legs), then adding a slow 3-second eccentric lowering phase. The CAE is combined with hip adductor concentric work (cable machine adduction, side-lying raises with increasing resistance) and core stability exercises targeting lumbopelvic control — plank, dead bug, and Copenhagen plank (side plank on adductor — the most advanced level of the Copenhagen progression).
4. Phase 3 — Sport-Specific Loading: Cricket, Football & Kabaddi
Phase 3 reintegrates sport-specific movement patterns that load the adductors in positions of maximum vulnerability — wide-stance lunging, kicking, and explosive lateral stepping. Our sport-specific protocol for cricket players addresses the side-on batting stance, the wide-crease stride in batting, and the bowling delivery stride where maximum hip abduction occurs. For football players at clubs in Bengaluru, we replicate the kicking, tackling, and cutting sequences with progressive intensity.
The progression ladder is: lateral lunges (bilateral) → lateral lunges (single-leg landing) → lateral bounding → diagonal cutting drills at 50%, 75%, 100% speed → kicking practice (cricket drive shots, football passing) at 50%, 75%, 100% power → full training participation. Pain must remain below 3/10 at each stage, with 24-hour pain monitoring between sessions.
5. Chronic Groin Pain & Athletic Pubalgia — When It Won't Heal
When groin pain persists beyond 6 weeks despite appropriate physiotherapy, we consider the diagnosis of chronic adductor tendinopathy or athletic pubalgia (sports hernia). Chronic adductor tendinopathy — analogous to Achilles tendinopathy — involves failed collagen remodelling and requires a heavy slow resistance (HSR) loading programme identical in principle to tendinopathy protocols elsewhere in the body. Athletic pubalgia involves tearing of the posterior inguinal wall and requires surgical referral to a sports hernia specialist.
Our physiotherapists at Curis 360 Banashankari differentiate these diagnoses using the clinical squeeze test battery and — when chronic — request an MRI pubic symphysis with dedicated adductor views. For confirmed chronic adductor tendinopathy, we prescribe a 12-week HSR programme using cable machine adduction, Copenhagen exercises with added load, and bilateral adductor squats (sumo squats). PRP injection is a secondary option for tendinopathy not responding to 12 weeks of supervised HSR, coordinated with our referring orthopaedic surgeons.
Frequently Asked Questions
How long before I can play football again after a groin strain?
Grade I strains typically allow return to training within 2–3 weeks. Grade II strains require 6–8 weeks of full rehabilitation. The criteria for return are: pain-free squeeze test at all angles, adductor strength >90% of the uninjured side, and completion of full sport-specific cutting and kicking drills without pain. Athletes who return too early have re-injury rates exceeding 50%.
Is groin pain always a muscle strain in cricketers?
Not always. In cricket fast bowlers, groin pain is often a combination of adductor strain, pubic symphysis stress reaction, and in some cases an early hip labral tear. In batsmen, adductor strains from the wide batting stance and hip mobility restrictions are common. Our Curis 360 assessment differentiates all these entities — because each requires a different management approach.
Should I rest completely with a groin strain?
Complete rest beyond 48 hours is not recommended. Early controlled loading (isometric squeezing exercises) from Day 2–3 is part of the optimal treatment protocol. The goal is to find the loading level that stimulates healing without exceeding the tissue's capacity — not to rest until the pain disappears, which often means the injury has become chronic.
Can I access groin strain physiotherapy online if I'm outside Bangalore?
Yes. Curis 360 offers online physiotherapy for groin strains across PAN India. We conduct a structured video assessment of hip mobility, adductor strength testing, and squeeze test via video call, prescribe and demonstrate the full Copenhagen programme and sport-specific loading progressions, and communicate directly with local sports medicine physicians for imaging coordination.
Stop living with Groin Strain & Adductor Injury
Our targeted physiotherapy protocols typically resolve this in 2–4 weeks (acute Grade I); 6–12 weeks (Grade II); 3–6 months (chronic/adductor tendinopathy).
