Abstract:

Objective To analyze the mental health and functional status of drug-dependent population by applying the theory and method of International Classification of Functioning, Disability and Health (ICF), explore the physical activity on the mental health pattern of drug-dependent population, and construct a theoretical framework, rehabilitation protocol and implementation plan for home exercise rehabilitation.

Methods The International Classification of Diseases (ICD-11) and ICF were used to systematically analyze the physical dysfunction (cognitive and motor), activity and participation of drug-dependent population. Based on the ICF bio-psycho-social model of functioning, disability and health, and with reference to the WHO Guidelines on Physical Activity and Sedentary Behavior, a home exercise rehabilitation program was constructed for the functional rehabilitation of drug-dependent population.

Results Functional impairment in the drug-dependent population was manifested in the physical function element mainly in mental dysfunction (b1), impaired cognitive function, reduced emotional control, impaired memory function, slowed thinking and personality disorders; while long-term drug use triggered a series of comorbidities, mainly in cardiopulmonary function (b4) and partial impairment of motor function (b7); and in the activity and participation element, learning and applying knowledge (d1), general tasks and demands (d2), self-care (d5), interpersonal and intrapersonal interactions (d7), and community, social, and civic life (d9) were limited. Physical activity was beneficial for the drug-dependent population to improve mental health, including cognition, attention, emotion, and thinking. A function-based exercise rehabilitation protocol was established. It recommended a programe of moderate intensity aerobic exercise, including walking, Tai Chi, Yoga, etc., four to five times a week for 150 to 300 minutesp; or high intensity aerobic exercise, including running, rope skipping, badminton, table tennis, martial arts, etc., two to three times a week for 75 to 150 minutes; moderate-intensity or high-intensity resistance exercises, such as push-ups, pull-ups, sit-ups and other major muscle group activities, two to three times a week with 30 to 60 minutes per time. The program of home exercise rehabilitation for drug-dependent population should be integrated into the four aspects of prevention, treatment, rehabilitation and health promotion in the community health service continuum, and provide home exercise rehabilitation services through offline guidance (professional guidance, group guidance, self-guidance) and online guidance (video instruction, remote online guidance, cloud supervision).

Conclusion A systematic analysis of the health condition and functional status of drug-dependent population has been conducted using ICD-11 and ICF, and a functional-oriented and holistic health-based home rehabilitation protocol has been developed based on the ICF bio-psycho-social model of functioning, disability and health, which may promote the recovery of cognitive, motor, activity, and participation functions of drug-dependent population, and help them reintegrate into family and society.
