The Effects of a Research-Based Exercise Program (Onero™) on Bone Mineral Density and Functional Measurements in Men and Women with Osteoporosis or Osteopenia in Hong Kong: A Case Study Series


Background: 59-year-old postmenopausal female breast cancer survivor w/ osteopenia and an atypical femoral fracture (AFF)


Exercise Intervention: Onero™ is a high-intensity resistance and impact training programme which consists of lifting weights, impact, and balance activities. The private sessions were 40 minutes in duration.

Client C attended a total of 16 sessions over a period of 39 weeks.

Measurements: The before and after exercise intervention DXA tests were taken at various radiology clinics in HK (chosen by the individual client) and included different regions of interest (ROI). Each client was able to be retested at the same radiology clinic using the same equipment.

The functional measurements tested gait speed, lower extremity strength, and balance. Measurements included the following tests: tandem gait, 5 times sit to stand (5xSTS),functional reach (FR), Timed up and Go (TUG), Tragus to Wall (TTW), Knees to Wall (KTW),Single Leg Stance (SLST).

Exercise Progression: The exercises were progressively increased in intensity and difficulty over the course of the program according to the subject’s capabilities.
