Suboccipital Muscle Inhibition vs IASTM for Forward Head Posture
Official title: Comparative Effects of Suboccipital Muscle Inhibition vs Instrument Assisted Soft Tissue Mobilization in Forward Head Posture
Run by Foundation University Islamabad · NCT07593235 · Data updated 2026-11-12
This trial tests whether suboccipital muscle inhibition or instrument-assisted soft tissue mobilization, added to standard physical therapy, better improves head-and-neck posture in people with forward head posture.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–40 years with forward head posture (CVA < 52°) and increased upper thoracic kyphosis.
✕Probably not a fit
Patients without improvements in craniovertebral angle or neck postural alignment despite the interventions might not experience benefit.

What this trial studies
In this randomized controlled trial, adults with forward head posture are assigned to receive 6 weeks of conventional physical therapy plus either suboccipital muscle inhibition (SMI) or instrument-assisted soft tissue mobilization (IASTM). Each participant attends 18 treatment sessions, including initial thermotherapy, with the two interventions differing by the manual technique applied to the suboccipital region or to soft tissues, respectively. The aim is to see which approach more effectively improves craniovertebral alignment and related postural parameters. Eligible participants are adults aged 18–40 with increased upper thoracic kyphosis and a craniovertebral angle less than 52 degrees, excluding those with cervical spine surgery or neurologic conditions. The study is conducted at Foundation University College of Physical Therapy in Islamabad, with the Foundation University Islamabad as lead sponsor.
Why it matters
Potential benefit: If successful, the findings could help clinicians choose between SMI or IASTM to improve head posture and reduce neck strain.
How similar studies have gone: Previous work in manual therapy for postural issues has shown benefits with both approaches, but direct head-to-head comparisons in forward head posture are limited.
