This randomized, sham-controlled, parallel, double-blind clinical trial investigates the effects of foot reflexology on anxiety and well-being in adults with anxiety disorders. Participants are randomized (1:1) to receive either standardized foot reflexology or sham massage for 10 sessions (twice per week, 5 weeks). The primary outcome is the change in Beck Anxiety Inventory (BAI) score from baseline to the 10th session. Secondary outcomes include BAI score at 30-day follow-up, relaxation and well-being assessed immediately after each session with the Profile of Mood States (POMS - Brazilian version, Tension-Anxiety subscale), and incidence of adverse events. It is hypothesized that foot reflexology will result in a greater reduction of anxiety symptoms compared to sham massage.
Participants aged 18-60 years with a clinical diagnosis of anxiety (DSM-5) are recruited and randomized 1:1 into two groups: Experimental: standardized foot reflexology protocol targeting reflex points (solar plexus, CNS, pituitary, heart, diaphragm). Sham comparator: foot manipulation and mobilization (sliding, flexion-extension, rotation, traction) without stimulation of reflex points. Both interventions last approximately 15 minutes per session, 10 sessions total (twice per week for 5 weeks). Assessments: BAI at baseline, after 5 sessions, after 10 sessions, and 30-day follow-up. POMS (Tension-Anxiety subscale) immediately after each session (sessions 1-10). Checklist for adverse events (e.g., redness, pain, tingling, transient discomfort). Blinding: Participants, care providers, outcome assessors, and statisticians are blinded to group allocation.

A complementary technique that involves applying pressure to reflexology points on the feet. In this study, foot reflexology will be applied in 10 sessions, twice a week, for 30 minutes, aiming to reduce anxiety symptoms.
A simulated procedure consisting of superficial and random maneuvers on the feet, without stimulation of specific reflexology points. Ten sessions will be conducted twice a week, each lasting 30 minutes, for placebo control purposes.

Reduction of Anxiety Symptoms (BAI)
Anxiety symptom variation was assessed using the Beck Anxiety Inventory (BAI), a validated and widely used scale for measuring the intensity of anxiety symptoms. The total score ranges from 0 to 63, with higher scores indicating greater anxiety. The analysis will compare the scores obtained in the first session (baseline), the fifth session, and the tenth intervention session.
Time frame: Baseline, after 5 sessions and after 10 sessions (approximately 5 weeks).
Reduction of tension-anxiety levels (Profile of Mood States - POMS, reduced version)
Assessment of subjective perception of relaxation and psychological well-being using the Tension-Anxiety subscale of the Profile of Mood States (POMS) - Reduced Version, validated for Portuguese. Scores range from 0 to 36, with higher scores indicating greater tension and anxiety and lower scores indicating greater relaxation and well-being.
Time frame: Baseline, after 5 sessions (approximately 2.5 weeks), and after 10 sessions (approximately 5 weeks).
Recording of adverse effects related to the intervention
Systematic monitoring and recording of any adverse effects reported during or after foot reflexology or sham reflexology sessions, including pain, discomfort, or unexpected reactions. Outcomes will be categorized by frequency (number of participants affected) and intensity (mild, moderate, severe).
Time frame: Throughout the intervention period (10 sessions - approximately 5 weeks).
