Abstract
Background: Anxiety disorders are characterized by excessive worry and apprehension that is often difficult to control, hence causing restlessness, palpitation, difficulty in breathing, concentrating, feeling sad or low mood leading to occupational functioning impairment. Sensory Modulation is the central nervous system’s neurological capacity to control environmental sensory stimuli and allow for a behavioural reaction to those stimuli. Researches indicate that that sensory modulation interventions have the potential in reducing distress levels, and modulating the arousal levels thereby improving the occupational participation of adults with mental illnesses. As there are fewer studies conducted on persons with anxiety disorder for sensory modulation intervention it is important to investigate further in this topic.
Objectives: To determine the effectiveness of sensory modulation intervention on persons with anxiety disorder
Study Design: Quasi Experimental Study
Method: Persons with anxiety disorder were selected using convenience sampling. The individuals who were chosen for inclusion and exclusion were screened using Beck's Anxiety Scale, with scores ranging from 20-69. The persons were grouped into experimental and control groups. The persons in the control group received conventional occupational therapy while those in the experiment group received sensory modulation intervention for a duration of 6-weeks. Before beginning with the intervention both groups completed Canadian Occupational Performance Measure (COPM) and WHO Disability Assessment Schedule 2.0 (WHODAS 2.0).
Results: Compared to the pre test, the mean scores of COPM for post test, in experimental group is more significant than the control group, meaning there was improvement in the experimental group after providing the intervention. Similarly, the WHODAS 2.0 outcome measures in post test has reduced significantly in experimental group than compared to control group meaning the rate of disability due to anxiety has reduced for the participants after providing the intervention.
Conclusion: COPM and WHODAS 2.0 findings demonstrate that sensory modulation interventions produce meaningful functional gains in adults with anxiety disorders, along with the occupational therapy‑based rehabilitation to enhance independence, participation, and quality of life.
