Description of intervention(s) / exposure
In this study, the Nintendo Wii Fit™ games and balance board system will be utilised as an exergaming intervention. A trained physiotherapist will conduct the balance exergaming in a set-up exergaming room at the School of Physiotherapy.

The balance board which measures 8.5’’ x 6’’ x 2’’ is an accessory for the Nintendo’s Wii video game console. It has a white top and a grey bottom, shaped like a weighing scale. The balance board is a wireless console that can support up to 300 lbs. The balance board contains several multiple pressure sensors that measure a player’s centre of balance and the body mass index (BMI). The balance board will be calibrated before the commencement of the study.

Participants will perform balance exercise for 45 to 60 minute, three times per week for an eight-week period. The games will include Table Tilt, Soccer Heading and Penguin Slide. These games were chosen due to their focus on weight shifting which is a component of postural balance. To monitor adherence, participants will be followed-up through phone calls.

Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria will include the presence of another concomitant lower extremity musculoskeletal condition, inflammatory arthritis, the presence of neurological diseases, previous history of lower limb joint replacement, the presence of cognitive deficits, and those with a vestibular problem. A participant who is receiving the current intervention or included in an ongoing study as well as with previous history of using exergaming will also be excluded.

Other design features
A mixed-methods, explanatory sequential study design will be conducted for piloting the Nintendo Wii Fit™ exergaming program in individuals with knee OA. This design emphasises quantitative analysis, which is followed by interviews or observations (qualitative) to help in analysing the findings. The quantitative part will be a one-way repeated measures design, while the qualitative part will be a focus group discussion.
