About this study
The aim of this research is to determines Combined Effect of Kendall exercises with Wearable vibrotactile feedback Sensor on Forward Head Posture correction on neck pain, and improving craniovertebral angle and muscle thickness. Randomized controlled trials at Fauji Foundation Hospital and Margalla Institute of health sciences . The sample size was 64. The subjects were divided in two groups, 32 subjects will be included in wearbable sensors and kendall exercises group and 32 will be in Kendell exercise alone . Study duration will be 12 months. Sampling technique applied will be non probability convinience sampling technique. Participants eligible for recruitment in this study will include young adults between the ages of 18 and 30 years. Eligible participants must also present with a craniovertebral angle (CVA) of less than 50 degrees, a body mass index (BMI) within the range of 18.5-30 kg/m², and a daily screen time of less than five hours. Data will be analyzed through SPSS version 26.
Read the detailed description
Forward Head Posture (FHP) is one of the most prevalent postural deviations among young adults, largely influenced by prolonged screen use, sedentary behaviors, and faulty sitting postures. This malalignment, characterized by anterior displacement of the head relative to the shoulder line, places excessive strain on the cervical spine and is strongly associated with neck pain, reduced craniovertebral angle (CVA), and muscular imbalances. If not corrected, FHP may contribute to long-term musculoskeletal dysfunction and impaired quality of life.
Conventional corrective approaches, such as the Kendall Exercise protocol, are widely recognized for addressing FHP by stretching shortened muscles (cervical extensors, pectorals) and strengthening weakened stabilizers (deep cervical flexors, scapular retractors). However, exercise-based interventions alone often face challenges of adherence and lack of postural awareness during daily activities.
Wearable vibrotactile feedback sensors have emerged as an innovative adjunct to exercise therapy. These devices provide real-time postural biofeedback, alerting users immediately when deviations occur and actively engaging them in maintaining correct alignment. By combining the Kendall Exercise protocol with wearable biofeedback technology, a more comprehensive approach may be achieved, addressing both neuromuscular strengthening and behavioral postural awareness.
Despite the increasing prevalence of FHP in young adults, limited evidence exists on the combined effect of structured exercise and wearable sensors. No randomized controlled trial has yet evaluated this integrated approach in this population. To address this gap, the present study will assess the combined effect of Kendall exercises and a wearable vibrotactile feedback sensor on forward head posture, neck pain, craniovertebral angle, and cervical muscle thickness in young adults.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2026.
