About

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.

Full description

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.

Masking: Triple Blind

---

120 participants in 2 patient groups

Experimental: Otago Exercise Programme (OEP)

Experimental group

Description:

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.

Treatment:

Behavioral: Otago Exercise Programme (OEP)

No Intervention: Usual Daily Activity (Control)

No Intervention group

Description:

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.
