Effectiveness of active physical training as treatment for long-standing adductor-related groin pain in athletes: randomised trial. Manual or exercise therapy for long-standing adductor-related groin pain: a randomised controlled clinical trial.
Groin pain is common among athletes. A major cause of long-standing problems is adductor-related groin pain. The purpose of this randomised clinical trial was to compare an active training programme (AT) with a physiotherapy treatment without active training (PT) in the treatment of adductor-related groin pain in athletes.
                68 athletes with long-standing (median 40 weeks) adductor-related groin pain--after examination according to a standardised protocol--were randomly assigned to AT or PT. The treatment period was 8-12 weeks. 4 months after the end of treatment a standardised examination was done. The examining physician was unaware of the treatment allocation. The ultimate outcome measure was full return to sports at the same level without groin pain. Analyses were by intention to treat.
                23 patients in the AT group and four in the PT group returned to sports without groin pain (odds ratio, multiple-logistic-regression analysis, 12.7 [95% CI 3.4-47.2]). The subjective global assessments of the effect of the treatments showed a significant (p=0.006) linear trend towards a better effect in the AT group. A per-protocol analysis did not show appreciably different results.
                AT with a programme aimed at improving strength and coordination of the muscles acting on the pelvis, in particular the adductor muscles, is very effective in the treatment of athletes with long-standing adductor-related groin pain. The potential preventive value of a short programme based upon the principles of AT should be assessed in future, randomised, clinical trials. A multi-modal treatment program (MMT) is more effective than exercise therapy (ET) for the treatment of long-standing adductor-related groin pain.
                Single blinded, prospective, randomised controlled trial.
                Patients: Athletes with pain at the proximal insertion of the adductor muscles on palpation and resisted adduction for at least two months. Interventions: ET: a home-based ET and a structured return to running program with instruction on three occasions from a sports physical therapist. MMT: Heat, Van den Akker manual therapy followed by stretching and a return to running program. Primary outcome: time to return to full sports participation. Secondary outcome measures: objective outcome score and the visual analogue pain score during sports activities. Outcome was assessed at 0, 6, 16 and 24 weeks.
                Athletes who received MMT returned to sports quicker (12.8 weeks, SD 6.0) than athletes in the ET group (17.3 weeks, SD 4.4. p = 0.043). Only 50-55% of athletes in both groups made a full return to sports. There was no difference between the groups in objective outcome (p = 0.72) or VAS during sports (p = 0.12).
                The multi-modal program resulted in a significantly quicker return to sports than ET plus return to running but neither treatment was very effective.

The available evidence from the randomized trials is insufficient to advise on any specific conservative modality for treating exercise-related groin pain. While still low quality, the best evidence is from one trial which found that exercise therapy (strengthening of hip and abdominal muscles) in athletes improves short-term outcomes (based primarily on pain measures) and return to sports compared with physiotherapy consisting of passive modalities. Given the low quality of the available evidence from both included trials, further randomized trials are necessary to reinforce their findings.
