PMID 29735473WHAT IT FOUND
Neither DVD nor website delivery of a home hip osteoarthritis exercise program clearly improved pain, hip function, quality of life, or self-efficacy, and the methods were similar.
Key findings
01Only 10 DVD and 18 website participants were included in the final analysis.
02Changes in pain, hip function, quality of life, and self-efficacy were not clearly confirmed after 6 months.
03The DVD and website modes did not show a clear difference in effectiveness.

What it does not show
The final analysis included only 10 DVD and 18 website participants. Patients were not randomly assigned; they were placed into DVD or website groups based on access to a DVD player or the Internet. The DVD and website groups were recruited in different time periods. Retention was low, and younger website nonrespondents may have changed the analysed sample. All participants came from one hospital, and most were middle-aged. The study did not show a clear difference between DVD and website delivery.
Declared interests
The paper states that conflicts of interest were not declared. No funding source is reported in the supplied text.
The easy way to misread this
Do not conclude that a DVD or website exercise program clearly improves hip pain or function. The final analysis included only 10 DVD and 18 website participants, the groups were not randomly assigned, and the paper says the improvements were not confirmed.
