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.

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.

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.
Time frame: Baseline, 6 weeks, and 12 weeks after intervention start
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.
Time frame: Baseline, 6 weeks, and 12 weeks after intervention start
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.
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: Baseline, 6 weeks, and 12 weeks after intervention start
