A vibration treatment has been proposed as a way of helping the body to mend fractures.
Researchers from the Medical College of Georgia conducted a study on 18-month-old male mice to assess the impact of the treatment.
The trial saw the mice administered daily 30-minute vibration sessions for a 12-week duration.
Following this, the animals did not show the expected loss of bone density which can precede problems such as fractures, disability and death among the elderly.
The mice were used because their age is the equivalent of a human aged between 55 and 65 years.
Dr Karl Wenger, biomedical engineer at the school, commented: "We think that in fracture healing, you get a more dramatic response.
"We don't know exactly why it affects the biology differently but it's likely because of the extent to which stem cells invade the injured area."
The doctor added that the study backed up existing evidence and could mean that the technique will provide a low-risk alternative to help heal fractures and improve bone condition.
