Effectiveness of Dry Needling in Athletes With Chronic Hamstring Strain

29. april 2026 oppdatert av: Amr Mostafa Kamal Anas, Cairo University

Effectiveness of Dry Needling on Athletes With Chronic Hamstring Strain

This study aims to evaluate the effectiveness of dry needling in reducing pain and improving functional outcomes in athletes with chronic hamstring strain. Chronic hamstring injuries are common among athletes and often lead to persistent pain, reduced performance, and limitations in daily and sports activities.

Dry needling is a therapeutic technique used to target myofascial trigger points and relieve muscle tension. This study will compare the effects of dry needling with conventional physiotherapy interventions to determine its role in managing chronic hamstring strain.

Participants will be athletes diagnosed with chronic hamstring strain. Outcomes will include pain intensity, muscle flexibility, and functional performance. The results of this study may help improve rehabilitation strategies and provide evidence for the use of dry needling in sports injuries.

Detaljert beskrivelse

Chronic hamstring strain (CHS) is a common musculoskeletal condition among athletes, particularly in sports involving high-speed running and sudden changes in direction. It is characterized by persistent or recurrent symptoms lasting more than three months and is often associated with reduced muscle flexibility, decreased performance, and an increased risk of reinjury.

Dry needling (DN) has emerged as a therapeutic intervention targeting myofascial trigger points to reduce pain, improve muscle function, and restore neuromuscular control. It is believed to act through both mechanical and neurophysiological mechanisms, including reduction of muscle tension and modulation of pain pathways.

This study aims to investigate the effectiveness of dry needling as an adjunct to conventional physiotherapy in athletes with chronic hamstring strain. Participants will be randomly assigned into two groups. The experimental group will receive dry needling combined with a structured physiotherapy program, while the control group will receive the same physiotherapy program without dry needling.

The physiotherapy program will include stretching exercises, strengthening exercises with an emphasis on eccentric loading, and functional training. Dry needling will be applied to identified trigger points in the hamstring muscles using standard clinical techniques.

Outcome measures will include pain intensity, hamstring flexibility, and functional performance. Assessments will be conducted before and after the intervention period.

The results of this study are expected to provide evidence regarding the added value of dry needling in improving rehabilitation outcomes for athletes with chronic hamstring strain.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: Control Group (A)
Participants will receive only the standard rehabilitation program without dry needling.
Fremgangsmåte: Standard Rehabilitation Program
Participants will receive a standardized rehabilitation program including stretching and eccentric strengthening exercises for hamstring muscles without dry needling.
Eksperimentell: Intervention Group (B)
Participants will receive dry needling treatment in addition to a standard rehabilitation program for chronic hamstring strain
Fremgangsmåte: Standard Rehabilitation Program
Participants will receive a standardized rehabilitation program including stretching and eccentric strengthening exercises for hamstring muscles without dry needling.
Fremgangsmåte: Dry Needling
Participants will receive dry needling treatment applied to active myofascial trigger points in the hamstring muscles (biceps femoris, semitendinosus, and semimembranosus). Sterile filiform needles will be inserted into identified trigger points to elicit local twitch responses and reduce muscle pain and tightness. Treatment will be performed in addition to a standardized rehabilitation program including stretching and strengthening exercises for the hamstring muscle group. Sessions will be administered over the study period according to a predefined treatment schedule.

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Pain Intensity
Tidsramme: Baseline (pre-intervention) and after 6 weeks of treatment
Pain intensity in chronic hamstring strain will be assessed using the Visual Analog Scale (VAS), a 10-cm scale ranging from 0 (no pain) to 10 (worst imaginable pain). Measurements will be taken at baseline and after completion of the intervention period to evaluate changes in pain perception.
