By way of illustration, current evidence shows a dose–response relationship between stretching intensity and flexibility, with higher-intensity stretching yielding greater acute flexibility gains (Thomas et al., <span>2018</span>).</p><p>In our study, we utilized a seated stretching position in the Biodex as it ensured good experimental control. However, this approach may have limited clinical applicability. Although the effect of different body positions during stretching on pain modulation was beyond the scope of the present study, current evidence indicates that comparable pain modulation effects from static stretching exercises can be achieved across various delivery methods, including home-based, therapist-guided and machine-assisted stretching approaches (Støve et al., <span>2021</span>; Støve, Hirata, & Palsson, <span>2024</span>; Støve, Thomsen, et al., <span>2024</span>).</p><p>We agree that the clinical implications of our findings go beyond basic static stretching and may extend to various exercise modalities that incorporate stretching elements, such as yoga, proprioceptive neuromuscular facilitation (PNF) and Tai Chi. However, additional work is needed to explore the factors that determine the analgesic effect of stretching exercises in different populations to enable the adaptation of interventions for diverse patient populations. The present results invite the hypothesis that the sensory perception of the stretching stimuli (e.g. the sensation of stretch, stiffness, discomfort or tightness) and the stretch duration may be key factors in determining the magnitude of stretch-induced hypoalgesia.</p><p>MPS wrote the first draft, which AR, LØH, KKE, JLT and SPM critically revised.
