The Stretch Zone® Effect

A Science-Backed Approach to Assisted Stretching

The only assisted stretching franchise with a proprietary protocol validated by research – as published in the Journal of Musculoskeletal Disorders and Treatment

Study Overview

A three-phased prospective cohort study assigned 32 participants to four conditions over 4 weeks. Three conditions received practitioner-assisted stretching at varying frequencies and durations, and one condition served as a no-stretching control.

Thirty-five range-of-motion (ROM) measures were taken through a goniometric test at baseline, post-program, and 30-day follow-up. The SF-36 instrument was used to assess the health status of participants.
