Gastrocnemius Muscle, Myofascial Pain Syndromes, Trigger Points
Conditions
Brief summary
This randomised single-blind trial will evaluate the immediate effect of a single session of dry needling versus sham needling on calf muscle myofascial trigger points among amateur football players aged 18-25 years. Primary and secondary outcomes are Pressure Pain Threshold (algometer), Sprint Speed (shuttle run test), and Functional Performance (single-leg hop). Outcomes will be measured immediately pre- and post-intervention. Data analysis will be performed in SPSS version 27 using paired and independent t-tests (p \< 0.05).
Detailed description
A randomised, single-blind, parallel-group trial recruiting amateur club football players (age 18-25) with active myofascial trigger points in gastrocnemius or soleus. Participants randomised (coin toss) into Group A (Dry Needling) or Group B (Sham Needling). Baseline measures: Pressure Pain Threshold (PPT) using handheld algometer, ankle dorsiflexion ROM with goniometer, sprint speed via shuttle run, and single-leg hop distance. Intervention: a single session of dry needling (sterile single-use filiform needles 0.25-0.30 mm; needles retained \ 10 minutes with fast-in/fast-out pistoning to elicit local twitch response) or a non-penetrating sham procedure mimicking needling. Post-intervention assessments are performed immediately after the session. Data will be analysed with SPSS v.27; paired t-tests for within-group and independent t-tests for between-group comparisons (p \< 0.05).
Interventions
PROCEDUREDry Needling
A single-session myofascial trigger point dry needling treatment will be administered to identified trigger points in the gastrocnemius and/or soleus muscles using sterile disposable filiform needles. The objective is to mechanically disrupt the dysfunctional motor end plate, elicit local twitch responses, reduce nociceptive activity, and restore muscle function. The intervention is delivered under aseptic conditions by a trained physiotherapist following standard safety guidelines. Post-procedure monitoring will be conducted for minor adverse effects such as soreness or bleeding.
PROCEDURESham Needling
A simulated needling procedure designed to act as a placebo comparator will be applied without skin penetration. The technique reproduces the visual, tactile, and contextual components of dry needling to maintain participant blinding while avoiding physiological stimulation of the muscle. This allows isolation of the true therapeutic effect of dry needling from psychological or expectancy-related responses.

SINGLE (Subject)
Masking description
Participants will be blinded to treatment allocation. The sham procedure mimics the sensation and setup of dry needling without skin penetration to maintain participant blinding, while the treating therapist cannot be blinded due to the nature of the intervention.
Intervention model description
Participant will be randomly allocated into two parallel groups; Group A: Dry needling intervention Group B : Sham Needling Control Both Group will undergo baseline assessment followed by a single treatment session and immediate post intervention reassessment. Outcomes will be compared between group.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain Pressure Threshold | Baseline (Day 0, pre-intervention) and Immediately Post-intervention (within 15 minutes after intervention). | Pressure Pain Threshold will be measured at the identified myofascial trigger point in the gastrocnemius or soleus using a handheld pressure algometer. The participant will indicate the point at which applied pressure first becomes painful. The recorded value (kg/cm²) reflects mechanical pain sensitivity of the trigger point. |
| Functional Performance | Baseline (Day 0, pre-intervention) and Immediately Post-intervention (within 15 minutes after intervention). | Functional performance will be assessed using Single leg hop test ( distance in centimeters).The Single Leg Hop Test measures lower limb explosive power. Participants will perform three maximal forward hops on one leg. The distance (in centimeters) from the starting line to the heel landing point will be recorded. The average of three trials will be used for analysis. Greater distance indicates improved functional performance. |
| Sprint Speed | Baseline (Day 0, pre-intervention) and Immediately Post-intervention (within 15 minutes after intervention). | Sprint speed will be accessed by Shuttle run test. The speed and agility of lower limb in calf muscle by time taken to complete a short distance shuttle sprint. It reflects the explosive function of calf muscle which is essential for acceleration and direction change in football. Sprint speed will be assessed using a 20-meter shuttle run test. Participants will run back and forth between two markers placed 20 meters apart as quickly as possible. Two trials will be performed, and the fastest time (in seconds) will be recorded to the nearest 0.1 second. Lower time indicates better sprint performance. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Range of Motion of Ankle Dorsiflexion | Baseline (Day 0, pre-intervention) and Immediately Post-intervention (within 15 minutes after intervention). | Ankle dorsiflexion will be measured in degrees using a universal goniometer. Three readings will be taken and averaged. Higher degrees indicate improved flexibility. |
