Abstract
Objective
To provide empirical evidence on the effect of early physical therapy (PT) within
the first year of osteoarthritis (OA) diagnosis on reduction in OA-related comorbidities
in patients with OA.
Design
Retrospective cohort study.
Setting
The study was conducted using a nationally representative sample of 1 million National
Health Insurance enrollees.
Participants
Newly diagnosed patients with OA (N=13,545). One-to-one propensity score matching
was used to match patients who received PT within the first year of OA diagnosis (PT
group; n=3403) with an equal number of patients with OA who did not receive PT (non-PT
group).
Interventions
Not applicable.
Main Outcome Measures
The 4-year cumulative risk of comorbidities including coronary artery disease (CAD),
diabetes mellitus, dyslipidemia, osteoporosis, gastrointestinal tract ulcer, and renal
failure was estimated. A Cox proportional hazards regression analysis was performed
to identify the dose-response relation between the PT dosage and the risk of OA-related
comorbidities.
Results
A total of 3403 patients (25.1%) received PT within the first year of OA diagnosis.
The PT group had a significantly lower 4-year cumulative risk of dyslipidemia (P=.05) and a potentially lower 4-year cumulative risk of CAD (P=.09). After adjusting for other potential confounders, the Cox proportional hazards
regression analysis showed that patients with OA who received a high PT dosage had
a low risk of CAD and dyslipidemia.
Conclusions
Patients with OA who received PT had a lower risk of OA-related comorbidities such
as dyslipidemia or CAD.
