Brief summary

The purpose of this study is to determine whether active stretching with low frequency currents are more effective than active stretching in the treatment of hamstring shortness syndrome in children.

Detailed description

In 2012 we studied 51 young footballers with Short Hamstring Syndrome in Spain. Three groups were formed: 1. Stretching+Transcutaneous Electrical Nervous Stimulation (TENS); 2. Active stretching; 3. Conventional stretching. Parameters: straight leg raise test (SLR), popliteal angle with the passive knee extension test (PKE) and the toe-touch test (TT). The inter-group means were compared and clinically relevant parameters calculated \[relative risk (RR), absolute risk reduction (ARR), relative risk reduction (RRR) and number needed to treat (NNT)\].

Interventions

PROCEDUREActive stretching

The participants performed three specific exercises of static active stretching of the hamstring muscles, maintaining the maximum tightness that was tolerable without pain for 15 seconds. Each exercise were performed twice, with a total of six repetitions.
