Immediate Effects of Abdominal Hypopressive Technique Versus PNF Stretching in Shortened Hamstring Syndrome: A Pilot Randomized Controlled Trial.

ABSTRACT:

Background and purpose

Short Hamstring Syndrome (SHS) is described as a deficit of extensibility of this musculature. In contrast to Proprioceptive Neuromuscular Facilitation (PNF), which is widely used in these cases, the abdominal hypopressive technique (AHT) is presented as a possible method to improve flexibility. The primary aim of this trial was to assess the feasibility and acceptability of a single-session AHT program versus PNF stretching in adults with SHS, while the secondary, exploratory aim was to estimate their immediate effects on hamstring flexibility to inform the design and sample size of a future definitive trial.

Methods

A pilot randomized controlled trial of a single treatment session was designed, with a pre- and post-treatment evaluation to assess the
