Summary

The goal of this clinical trial is to evaluate whether a structured reflexology therapy can improve sleep, reduce insomnia severity, and alleviate fatigue in adults with poor sleep quality, and to understand how it affects autonomic nervous system function. The main questions it aims to answer are: * Can manual reflexology treatment improve sleep quality as measured by standardized sleep assessments? * Can manual reflexology influence physiological measures of autonomic function (such as heart rate and heart rate variability)? Researchers will compare the effects of a manual reflexology intervention to those of a mechanical foot massage to determine which approach is more effective in improving sleep, reducing insomnia severity, and enhancing fatigue and autonomic balance. Participants will be asked to: * Undergo weekly sessions of manual reflexology therapy for six weeks, and * Undergo weekly sessions using mechanical foot massage equipment for six weeks, with heart rate, heart rate variability, and sleep and fatigue questionnaires measured before and after each intervention period.

Detailed description

Poor sleep quality is a common health concern associated with impaired autonomic nervous system regulation and increased risk of physical and psychological disorders. Complementary therapies, such as foot reflexology, are widely used to promote relaxation and improve sleep; however, evidence regarding their physiological effects and comparative effectiveness remains limited. This study was designed to examine whether a structured manual reflexology treatment can improve sleep-related outcomes and autonomic nervous system function in adults with poor sleep quality, compared with mechanical foot massage. Participants enrolled in this study undergo two different foot-based interventions-manual reflexology treatment and mechanical foot massage-delivered in separate intervention periods. Each intervention period lasts six weeks, with one session per week. The order of interventions is assigned using a randomized crossover design, allowing each participant to receive both treatments while minimizing individual differences. Manual reflexology sessions are delivered by a trained practitioner following a standardized and reproducible protocol, which targets specific foot reflex zones associated with relaxation and autonomic regulation. Mechanical foot massage sessions are conducted using commercially available foot massage equipment under standardized conditions. Both interventions are designed to be non-invasive and well tolerated. Throughout the study, participants' physiological responses are monitored using non-invasive measures of heart rate and heart rate variability, which provide insight into autonomic nervous system activity. In addition, participants complete validated questionnaires assessing sleep quality, insomnia severity, and fatigue. By comparing changes observed after each intervention, this study aims to clarify whether manual reflexology offers added benefits over mechanical massage and to explore the potential role of autonomic modulation in improving sleep-related outcomes.

Interventions

Type	Name	Description
BEHAVIORAL	manual reflexology treatment	The manual reflexology procedure was carried out following a standardized sequence, targeting specific foot reflex zones. The detailed steps were as follows: 1. Preparation: All participants were positioned in a semi-recumbent supine posture on a treatment bed, with appropriate towel draping to ensure comfort and privacy. The massage bed and chair were disinfected with 75% alcohol and covered with a clean foot towel. 2. Foot Relaxation Techniques: The treatment began with relaxation techniques (e.g., friction and oscillation) applied first to the left foot, followed by the right. 3. Reflex Zone Stimulation Techniques: Five core massage techniques-pressing, kneading, pushing, scraping, and acupressure-were applied systematically across different reflex zones, as described below: I. Toe Region (2 min/foot): Brain, frontal lobe, pituitary gland, temples, cerebellum, nose, cervical area, eyes, ears, upper/lower jaw, tonsils, vocal cords, esophagus, and trachea. II. Medial Foot (2 min/
BEHAVIORAL	Feet massage using an electric massager (FEM)	Each session lasted 30 minutes and was conducted using the device's pre-set "fatigue relief" mode, which applied medium-intensity pressure combined with a mild heating function. The massage covered the following regions with different mechanical actions. (1) Plantar region (sole of the foot): Targeted zones included the thoracic, abdominal, and pelvic areas. The massage's methods were delivered using rolling, pressing, squeezing, and vibration techniques. (2) Medial and lateral sides of the foot: These areas were stimulated through squeezing, pressing, and vibration. (3) Dorsal foot region (top of the foot): This region was massaged using squeezing, pressing, and vibration. (4) Calf region: The device provided massage through squeezing, pressing, and vibration to promote circulation and muscle relaxation. All participants received the same standardized massage setting to ensure consistency throughout the intervention period.
