The goal of this clinical trial is to learn whether home-based progressive lower extremity resistance training with elastic bands improves balance in older adults (aged 60 years or older) after primary unilateral hip arthroplasty. The main question it aims to answer is: does 6 weeks of elastic-band resistance training at home reduce Timed Up and Go (TUG) time more than routine home lower extremity exercise? Researchers compared an elastic-band resistance training group with a routine home exercise group to see whether balance, measured by TUG, improved more with resistance training. Participants were asked to: attend a baseline visit for assessment, exercise testing and education; perform their assigned home exercise program for 6 weeks; record their exercise in a logbook; and return for a repeat TUG assessment after 6 weeks.
Older adults commonly have persistent lower extremity muscle weakness and impaired balance after hip arthroplasty, which keeps fall risk high. This single-center, parallel-group randomized clinical trial was conducted at the outpatient unit of the Department of Medical Rehabilitation, Dr. Cipto Mangunkusumo National General Hospital, Jakarta, Indonesia. Patients who had undergone primary unilateral hip arthroplasty were identified from electronic medical records. After written informed consent, participants were randomized a 1:1 ratio, using a computer-generated random list in Microsoft Excel, to an intervention group or a control group.
At the baseline visit, all participants underwent assessment of medical, functional and social history, cognition (Montreal Cognitive Assessment Ondonesian version, MoCA-INA), sensory integration (Clinical Test of Sensory Interaction on Balance, CTSIB) and balance (Timed Up and Go, TUG), and received education with their caregivers on exercise preparation, criteria for stopping exercise, pulse counting, the Borg rating of perceived exertion and logbook completion.
The intervention group performed progressive resistance training with beginner-level TheraBand elastic bands (yellow, red, green) at an initial load of 50% of one-repetition maximum, comprising seated knee extension, knee flexion and hip abduction, and sit-to-stand. Each 40-minute session (warm-up, main exercise, cool-down) was performed at home three times per week for 6 weeks. Band resistance was retested and progressed every 2 weeks, and adherence was monitored weekly by WhatsApp or telephone. The control group received routine home lower extremity exercise guided by an illustrated leaflet with an exercise checklist.
The primary outcome was TUG time, measured at baseline and after 6 weeks. The sample size was calculated for 90% power to detect a 6.3-second reduction in TUG. Within-group changes were analyzed with the paired t-test and between-group differences in TUG change with the Mann-Whitney U test; p-value \< 0.05 was considered significant.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Home-based progressive lower extremity resistance training with elastic bands for 6 weeks, with weekly remote monitoring
Behavioral: Elastic band resistance training
Routine home lower extremity exercise guided by an illustrated educational leaflet for 6 weeks
Behavioral: Routine home lower extremity exercise
Beginner-level TheraBand elastic bands (yellow, red, green) at an initial load of 50% of one-repetition maximum. Seated knee extension, knee flexion, hip abduction and sit-to-stand; 40-minute sessions (warm-up, main exercise, cool-down), 3 times per week at home for 6 weeks. Resistance retested and progressed every 2 weeks; adherence monitored weekly via WhatsApp or telephone; exercise logbook.
Also known as: TheraBand, progressive resistance training
Education on home lower extremity exercise, exercise preparation and criteria for stopping exercise, with an illustrated leaflet and exercise checklist, for 6 weeks.
Also known as: usual care home exercise
Change in Timed Up and Go (TUG) time
Time in seconds to rise from a 45-cm chair, walk 3 m, turn, walk back and sit down. Lower values indicate better balance and mobility.
