IRCT20230410057876N1 IRCT 2025-07-20 Mashhad University of Medical Sciences Abdominal Muscles Training in groin pain Effectiveness of hip muscle training with and without focus on abdominal muscles on pain, range of motion, hip muscle strength, physical performance and patient-reported outcomes in athletes with longstanding adductor-related groin pain: A randomized controlled trial 2025-06-10 anticipated 30 Complete https://irct.ir/trial/83406 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, a block randomization method of size four will be used to allocate participants to two treatment groups. Each block will include two participants from the control group (A) and two participants from the intervention group (B). In order to reduce bias and maintain statistical balance between groups, different orders of block sequences will be considered. Allowed combinations include: AABB, ABAB, ABBA, BBAA, BABA, and BAAB. Random sequences will be generated using the reputable website Sealedenvelope.com. The resulting sequences will be placed in opaque, sealed envelopes, and upon participant arrival, the sample allocator will randomly open one of the envelopes. The participant will be assigned to the appropriate group according to the order listed on the envelope. In order to conceal allocation and prevent bias in the selection process, sealed envelopes will be used and will be prepared by individuals unaware of the study contents, Blinding description: In this study, a blinding approach will be implemented involving both the outcome assessor and the data analyst. An independent evaluator will be designated as the outcome assessor, who will have no involvement in the study design, intervention delivery, or group allocation process. The assessor will remain fully blinded to the group assignments and intervention details. Clinical outcomes will be evaluated at two time points: baseline (prior to the intervention) and immediately after completion of the intervention period (week 8). Furthermore, data analysis will be conducted under blinded conditions. Prior to statistical processing, the dataset will be anonymized such that group identifiers are replaced with neutral codes (e.g., Group 1 and Group 2). The analyst will receive the de-identified data and will be unaware of the actual treatment allocation until the analysis is finalized. N/A Longstanding groin pain related to the adductor muscles. Intervention 1: Intervention group: Athletes in the intervention group will perform exercises under the supervision of one of two sports physiotherapists in the sports club for 6 weeks (3 days per week, odd days). Both physiotherapists will be trained in advance to provide a standard therapeutic exercise. Since the reduction in the strength of adductor muscles is evident in people with chronic groin pain and therapeutic exercise focused on isometric and eccentric strength of adductor and abductor muscles has been recommended in previous studies to reduce pain and restore function in athletes with chronic groin pain, the exercises provided for the muscles in question will also include these types of contractions, since in athletes with chronic groin pain, these two muscles are more likely to change than others among the trunk muscles. Therefore, exercises with maximum contraction of these muscles are recommended. The therapeutic exercise program of the intervention group includes strengthening the thigh muscles along with strengthening the abdominal muscles. The approximate duration of each session will be 60 minutes. Warm-up, fixed hip adduction, bilateral hip adduction, lateral hip adduction, hip abduction/adduction glide, machine adduction, Copenhagen adduction. Core exercises: Plank with leg raise, crunch, bird-dog exercise. Intervention 2: Control group: Athletes in the control group will be supervised by one of two sports physiotherapists in a sports club for 6 weeks (3 days per week, even days). Both physiotherapists will be trained in advance to provide a standard therapeutic exercise. Research shows that weakness in adductor muscle contractions is a common problem in people with chronic groin pain. Also, previous studies have shown that therapeutic exercises focusing on strengthening isometric and eccentric contractions of adductor and abductor muscles can help reduce pain and improve performance in athletes. Therefore, the proposed exercises will include these types of contractions. The approximate duration of each session will be 45 minutes. Warm-up, fixed thigh adduction, bilateral thigh adduction, lateral thigh adduction, thigh abduction/adduction, adduction with a device, Copenhagen adduction. Yes - There is a plan to make this available What will be shared: Only information related to the primary outcome (pain during function) can be shared after the study is completed.
