This randomized controlled trial aims to evaluate the effects of the Otago Exercise Programme (OEP) on physical fitness, balance, and quality of life among older adults in Sarawak, Malaysia. The intervention involves a structured home-based and group-supervised exercise programme focused on lower-limb strength and balance training. A total of 120 community-dwelling older adults aged 60 years and above were recruited from Bau District, Sarawak, and randomized into intervention (OEP) and control groups. The intervention group participated in the OEP for 12 weeks, while the control group maintained their usual activities.
Assessments were conducted at baseline, 6 weeks, and 12 weeks using the Senior Fitness Test (SFT), Berg Balance Scale (BBS), and WHOQOL-BREF to evaluate changes in physical fitness, balance, and quality of life. The study aims to provide evidence on the effectiveness of OEP as a feasible, community-based fall-prevention and functional fitness programme for older adults in Malaysia. Findings will contribute to national healthy ageing policy and rehabilitation strategies under the WHO Decade of Healthy Ageing (2021-2030) framework.
This study used a two-arm, parallel-group randomized controlled trial design to evaluate the effectiveness of the Otago Exercise Programme (OEP) in improving physical fitness, balance, and functional mobility among community-dwelling older adults in the Bau District of Sarawak, Malaysia.
Participants were screened for eligibility and safety using clinical history, medical clearance forms, and physical readiness questions. Randomization was conducted using computer-generated permuted blocks, with allocation sequences prepared and concealed by an independent coordinator not involved in assessment or intervention delivery.
The intervention protocol followed the standardized OEP training manual and included lower-limb strengthening, balance exercises, functional mobility tasks, and progressive walking prescriptions. Participants performed three weekly home-based sessions supported by weekly group-supervised sessions led by trained facilitators. Exercise progression was individualized according to participant capability and safety guidelines.
Outcome assessments were conducted at baseline, week 6, and week 12 by assessors who were blinded to group allocation. Standardized measurement procedures were used following the Senior Fitness Test (SFT) manual and the Berg Balance Scale (BBS) assessment protocol. Adverse events and training adherence were monitored throughout the intervention period.
The study operated under ethical approval from the Medical Research Ethics Committee, Universiti Malaysia Sarawak (Ref: FME/24/115). This project was conducted as part of a Doctor of Public Health (DrPH) research requirement. Findings are expected to contribute evidence for community-based fall-prevention strategies and healthy ageing programmes in Malaysia.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Experimental: Otago Exercise Programme (OEP) | Experimental | Participants in the intervention group will receive the Otago Exercise Programme (OEP), a structured, multicomponent home- and group-based exercise programme focusing on lower-limb strength, balance, and functional mobility. Each supervised session lasts about 60 minutes and includes warm-up, strengthening, balance, and cool-down exercises. Sessions are conducted three times weekly for 12 weeks under supervision by trained facilitators, with participants encouraged to continue selected exercises at home. |
|
| No Intervention: Usual Daily Activity (Control) | No Intervention | Participants in the control group will continue their usual daily activities and will not participate in any structured exercise programme. They will receive general health education leaflets on physical activity and fall prevention at baseline, without additional supervised training. |

|---|---|---|---|---|
| Otago Exercise Programme (OEP) | Behavioral | The Otago Exercise Programme (OEP) is a behavioural, multicomponent exercise protocol focusing on lower-limb strength, balance, and functional mobility. It includes warm-up, strengthening, balance, and cool-down components performed three times weekly for 12 weeks under trained supervision. The programme aims to improve balance, enhance lower-limb strength, and reduce fall risk among community-dwelling older adults. |
| Measure | Description | Time Frame |
|---|---|---|
| Balance performance measured using the Berg Balance Scale (BBS) | Balance ability will be assessed using the Berg Balance Scale (BBS), a 14-item objective measure designed to evaluate balance in older adults. Each item is scored on a 5-point scale (0-4), with a total possible score of 56. Higher scores indicate better balance and lower fall risk. | Baseline, 6 weeks, and 12 weeks after intervention start |
| Measure | Description | Time Frame |
|---|---|---|
| 30-Second Chair Stand Test Performance | The 30-second chair stand test will assess lower-body strength. Participants will be instructed to stand up fully and sit down as many times as possible within 30 seconds. Higher scores represent greater lower-body strength. | Baseline, 6 weeks, and 12 weeks after intervention start |
| Measure | Description | Time Frame |
|---|---|---|
| Quality of life measured using the WHOQOL-BREF questionnaire | Quality of life will be assessed using the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, which consists of 26 items covering four domains: physical health, psychological well-being, social relationships, and environment. Higher domain scores indicate better quality of life. | Baseline, 6 weeks, and 12 weeks after intervention start |

Individual participant data (IPD) will not be shared because the dataset contains identifiable information related to community-dwelling older adults in Sarawak. Data access is restricted under the Universiti Malaysia Sarawak (UNIMAS) Medical Ethics Committee approval. Only aggregated or anonymized results will be available upon reasonable request to the corresponding author.

Participants were randomly assigned into two parallel groups: an intervention group receiving the Otago Exercise Programme (OEP) and a control group continuing their usual daily activities without structured exercise. Both groups were followed for 12 weeks with assessments at baseline, 6 weeks, and 12 weeks.

Triple-blind randomized controlled trial. Participants, investigators, and outcome assessors were blinded to group allocation. Randomization codes were generated and maintained by an independent coordinator until completion of all data collection and analyses to prevent bias.

| Arm Curl Test Performance |
Upper-body strength will be assessed using the Arm Curl Test. Participants will perform as many arm curls as possible in 30 seconds using a standardized dumbbell (5 lbs for women and 8 lbs for men). A higher number of repetitions indicates greater upper-body strength. |
| Baseline, 6 weeks, and 12 weeks after intervention start |
| 2-Minute Step Test Performance | Aerobic endurance will be assessed using the 2-minute step test. Participants will march in place for 2 minutes, lifting the knees to a height midway between the patella and iliac crest. The number of steps meeting the required height will be counted. Higher numbers indicate greater aerobic endurance. | Baseline, 6 weeks, and 12 weeks after intervention start |
| Chair Sit-and-Reach Test Performance | Flexibility will be assessed using the chair sit-and-reach test. Participants will sit on the edge of a chair with one leg extended and reach toward the toes. The distance reached (positive score for reaching past the toes, negative score if short of toes) will be recorded. Higher values indicate better lower-body flexibility. | Baseline, 6 weeks, and 12 weeks after intervention start |
| Back Scratch Test Performance | Upper-body flexibility will be assessed using the back scratch test. Participants will place one hand over the shoulder and the other behind the back, attempting to touch or overlap the middle fingers. The distance between the fingertips (positive score for overlap, negative for gap) will be recorded. Higher values indicate better upper-body flexibility. | Baseline, 6 weeks, and 12 weeks after intervention start |
| 8-Foot Up-and-Go Test Performance | Agility and dynamic balance will be assessed using the 8-foot up-and-go test. Participants will rise from a seated position, walk 8 feet, turn around, and return to sit down as quickly as possible. The total time taken (in seconds) will be recorded. Shorter times indicate better agility and dynamic balance. | Baseline, 6 weeks, and 12 weeks after intervention start |
