PMID 32982050WHAT IT FOUND
Both muscle-strengthening exercises and visual feedback balance training reduced pain and improved function in older adults with knee arthritis.
However, adding visual feedback to standard therapy did not show a significant advantage over standard therapy alone.
Key findings
01Both the control group and the experimental group showed significant decreases in pain (VAS) and improvements in physical function (K-WOMAC) after treatment.
02There was no significant difference between the control group and the experimental group in pain or physical function after treatment.
03The control group performed muscle-strengthening exercises using elastic bands, while the experimental group performed visual feedback balance training using a computer game system.

What it does not show
The sample size was small (26 patients), which limits the generalizability of the findings. The study did not report long-term follow-up results. The lack of significant difference between groups might be due to the small sample size or the high effectiveness of the control intervention (elastic band exercises).
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that visual feedback balance training is ineffective. The study showed it improved pain and function, but it did not prove it was superior to simple elastic band exercises. Both interventions worked.
