Bone Mineral Density (BMD)
• Why BMD?
• How is BMD improved?

Intermittent Pneumatic Compression (IPC)
• What is IPC?
• How could IPC help BMD?

OUR STUDY/ METHODS
RESEARCH QUESTIONDOES AN IPC INTERVENTION INCREASE
BONE MINERAL DENSITY IN HEALTHY ADULTS?
• 10 Participants (4 Male, 6 Female)• Pre-Intervention Testing• IPC Intervention• Post-Intervention Testing
• 9 Participants (3 Male, 6 Female)
RESULTS
Table 1 Baseline Descriptive Characteristics
M=males, F=females, BMI= body mass index, MET=metabolic equivalent
RESULTSParticipants 1, 3, 4, and 6 demonstrated no change in BMD at the
nontreated hip

Our Study
DISCUSSIONAlbertazzi, P, Steel, SA, & Bottazzi, M, Bone. (2005) 37(5):662-668

• Found and increase in BMD at the hip
• 30 post menopausal women
• IPC intervention: 2 hours/day, 24 weeks
No current injury
• Only 2 post menopausal participants
• Shorter duration
• 30 post menapausal participants
• Longer duration
• Current fracture
• No history of fracture• Mixed gender
• 10 week intervention• Found and increase in BMD in the radius after a
radial fracture• 21 participants
• IPC intervention: 20 minutes/day, 10 weeks
Challis & et alAlbertazzi & et al
CONCLUSION
The results of this preliminary investigation suggest that IPC may be osteogenic and warrants further investigation as a means to reduce outcomes of osteoporosis
