PMID 27296899WHAT IT FOUND
In 325 patients with knee OA and meniscal tear, 38% did not stick with exercise over 12 weeks.
Lower income and no pain with pivoting or twisting were linked to more missed therapy and home exercise.
Key findings
01124 patients (38%) were less than 50% adherent to exercise over 12 weeks.
02In adjusted analysis, patients earning $29,000 or less per annum were 1.6 times as likely to be non-adherent as those earning $100,000 or more.
03Patients without pain with pivoting or twisting were 1.6 times as likely to be non-adherent as those with such pain.

What it does not show
This was a secondary analysis of trial data, not a study designed to explain why patients did not adhere. The biweekly calls did not ask patients to give reasons for non-adherence. Twenty-six of 351 patients were excluded because they provided no usable exercise data. Data on medication use during the trial were not available, so medication effects on motivation could have confounded the results. The analysis did not measure self-regulation or goal-setting. The cohort was mostly white, well educated, and employed, so the findings may not apply to more diverse populations. The study found associations, not proof that these factors caused non-adherence.

The easy way to misread this
Do not read lower income or no pain with pivoting and twisting as proof of why patients miss exercise. This was an observational secondary analysis, and the study did not ask patients why they did not adhere.
