Description of intervention(s) / exposure
Patients found to have impaired balance and vitamin D deficiency after assessment in The Nepean Hospital falls and fracture prevention clinic are recruited. Sixty patients (30 cases and 30 controls) fitting the inclusion criteria will be recruited at the Falls and Fractures Clinic, Nepean Hospital. The following parameters will be evaluated at baseline: balance performance measured by our balance rehabilitation unit (BRU), gait parameters (GaitRITE), serum levels of vitamin D, calcium, albumin and parathyroid Hormone (PTH). Patients with poor balance performance and low levels of vitamin D will be then randomised to receive either one intramuscular injection dose of vitamin D3 of 50,000 International Units or 1 ml (Arachitol, Solvay Pharma, India) or one intramuscular injection dose of placebo (1 mL of normal saline). All patients will receive calcium 1,200 mg orally once daily for the duration of the study ( 9 weeks) and commences immediately after the vitamin D3/placebo injection. After three weeks of randomization and treatment, all subjects will attend the standard balance rehabilitation program for six weeks. The program is run by a physiotherapist trained in using the balance rehabilitation unit machine. The program consists of two half hour sessions per week and runs for 6 weeks. Once patients complete 6 weeks of BRU, new balance, gait and serological assessment will be performed. Patients will be unblinded when all patients have completed the 6-week assessment. Patients in the placebo will then be supplemented with high dose vitamin D.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients who are assessed in the falls and fracture prevention clinic and are found to have impaired balance and low vitamin D will be recruited. The research officer will contact these potential participants by phone and appointment arranged to obtain consent. A sample of about sixty patients whose identitiy and details are coded will be fed into a computer software to generate randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
permuted block randomisation
Masking / blinding
Blinded (masking used)

Summary
Brief summary
Vitamin D deficiency becomes more common in the older persons. Vitamin D have been proven to reduce falls. How this benefit is achieved is not clearly known. We suspect that Vitamin D supplementation enhances balance performance in the elderly persons who suffer falls.
