A Comprehensive Intervention Program of Static-dynamic Balance Training Combined With Reminiscence Therapy on the Level of Healthy Aging Among Older Adults in a Rural Community

The Static-Dynamic Balance Training Combined with Reminiscence Therapy (SDBT-RT) program, grounded in the Theory of Planned Behavior, was designed to promote positive health behaviors. Guided by TPB, an SDBT-RT program was developed, taking into account the rural community context-including local policies, lifestyle habits, and social networks-as well as individual-level characteristics. The formulation of a research protocol that incorporates the model's core constructs warrants further investigation. At the level of behavioral attitude, reminiscence therapy sessions are used to evoke positive memories, foster a constructive outlook on aging, and strengthen the belief that "participating in this program can enhance my well-being". At the subjective norm level, the group-based intervention delivered in community centers helps establish supportive social norms. Peer observation and interaction reduce perceived barriers to participation. For perceived behavioral control, the SDBT component employs a progressive difficulty structure and real-time movement guidance to lower the perceived difficulty of performing the exercises.

The program was reviewed and revised by five experts in sports rehabilitation, medical psychology, geriatrics, health management, and nursing. Additionally, a pilot study was conducted prior to the main study to assess the feasibility of the intervention. The static-dynamic balance training component was derived from balancing postural control movements, with a gradual increase in intensity by varying sensory inputs and external distractions, and consisted of three parts: (1) a 10-minute warm-up phase (including range-of-motion exercises for the wrists, hips, shoulders, knees, and ankles); (2) a 15-minute static balance training session (standing on both feet; standing in parallel and tandem; standing in tandem; standing on one foot); and (3) a 25-minutes of dynamic balance training (normal gait; narrow gait; overlapping gait; tandem gait). RT is based on Erikson's theory of psychosocial development, which states that recalling life experiences can help rural older adults resolve the psychological crisis of integration and despair in the final stages of life. Therefore, a structured procedure of reviewing the past, returning to the present, evaluating the past, and facing the present was set up and, combined with the temporal characteristics of older Chinese people's lives, recreational activities, and traditional cultural practices; reminiscence therapy involves six themes: "Our Time," "My Happy Times," "Achievements in my life," "Revisiting Traditional Festivals," "My Hobbies," and "Feeling the good old days," promoting their self-integrity and optimism to face reality with positive goal orientation. Table 1 provides the content of the SDBT-RT.

Each group of interveners consists of general practitioners, community health workers and medical postgraduate students who have undergone one month of specialized training. Thirty-two people in the intervention group were randomly divided into 8-person groups, and the appropriate time periods (8:00-10:00) were selected according to the activity habits of the elderly in the community. The intervention sites are fixed as community activity centers equipped with multimedia facilities and green rest areas. The intervention lasted for 12 weeks. In odd-numbered weeks, a dual intervention model of "40-minute RT + 50-minute SDBT" was adopted to establish behavioral intentions, and behavioral attitudes and subjective norms were strengthened through RT. Synchronous balance training enhances perceptual behavioral control through immediate improvement of physical functions. In even weeks, only 50 minutes of SDBT is conducted. A single training can reduce cognitive load and focus on the solidification of motor skills. To record engagement in reminiscence therapy, a standardized observation checklist and participant feedback forms were used after each session to assess participation and emotional responses. Facilitators were trained to recognize distress or fatigue, with activities adapted to individual conditions and emergency protocols in place for physical or psychological incidents.

The implementer is required to fill out the "Implementation Fidelity Checklist" immediately after each session, recording whether the RT theme is carried out as per the weekly plan, whether the SDBT training is upgraded in stages, and the duration of the core links. The project supervisor randomly selects 20% of the checklists every week for phone review. When deviations are found, the implementers are required to explain the reasons and formulate improvement measures at the weekly regular meeting. Meanwhile, the implementers also need to record the physical and mental states of the participants and use resources such as unified theme audio and video, handicraft materials, festival decorations and life goal lists. During the intervention period, the intervention coordinator recorded the attendance of each participant in each course and promptly followed up on those who were absent to arrange make-up classes as much as possible. A "Behavior Log Form" was designed to record changes such as supplement use, recreational activities, and disease conditions. It was reviewed monthly by general practitioners to ensure that the intervention effect was not interfered with by confounding factors. During the 4-week follow-up, participants in the intervention group received four brief weekly phone calls (5-10 minutes each) to check on home practice adherence, provide encouragement, and answer basic questions. No new intervention content was introduced.
