Predictive factors for improvements in pain and physical function after progressive resistance training or neuromuscular exercise in hip Osteoarthritis. An exploratory analysis from the hip booster trial

Review written by Diogo Gomes info

Key Points

  1. Female sex, no prior exercise therapy, no use of analgesics, lower levels of BMI, and worse pain and physical function were associated with greater effects for pain and physical function in patients with hip osteoarthritis (OA).

BACKGROUND AND OBJECTIVE

Exercise, along with education and weight loss, is recommended as a first-line treatment for patients with hip osteoarthritis (OA). However, current evidence indicates that a large proportion of patients with hip OA do not respond to exercise-based interventions (1). Knowing which patients are likely to improve with exercise-based rehabilitation—and which are not—can help clinicians guide them toward the most appropriate treatment pathway, saving time and resources and reducing potential frustration with treatment. The question is: can we identify factors that predict how patients with hip OA will respond to exercise interventions?

This study was a secondary analysis of the Hip Booster Trial. The primary aim was to explore if baseline characteristics of participants were associated with the changes in hip pain and physical function after a 12-week exercise intervention.

Exercise, along with education and weight loss, is recommended as a first-line treatment for patients with hip osteoarthritis.

The benefits of exercise include increasing physical activity levels, encouraging patients’ to better understand and take interest in their condition, boosting confidence and self-efficacy, and reducing fear of movement.
