Hip Fractures, Mild Cognitive Impairment

Mobility, Exercise, Fall Risk
Brief summary
Hip fracture is recognized as one of the most serious consequences of osteoporosis, less than half regain pre-fracture independence. 95% of all hip fractures in older adults are due to falls. Thus, reducing fall risk while restoring function post-hip fracture is critical. Many with fall-related hip fractures have cognitive impairment; cognitive impairment increases the risk of falls. The purpose of this 6-month proof-of-concept randomized controlled trial (RCT) is to assess the efficacy of the home-based Otago Exercise Program (OEP) compared with usual care in reducing fall risk among older adults with mild cognitive impairment (MCI) and a fall-related hip fracture.
Detailed description
Hip fracture is recognized as one of the most serious consequences of osteoporosis, less than half regain pre-fracture independence. 95% of all hip fractures in older adults are due to falls. Thus, reducing fall risk while restoring function post-hip fracture is critical. Many with fall-related hip fractures have cognitive impairment and they are less likely to regain pre-fracture level of function than those without cognitive impairment. Cognitive impairment also increase falls risk. It is currently unknown whether exercise is efficacious in reducing fall risk and promoting function among older adults with mild cognitive impairment (MCI) and a fall-related hip fracture. The purpose of this 6-month proof-of-concept RCT is to assess the efficacy of the home-based Otago Exercise Program (OEP) compared with usual care in reducing fall risk among community-dwelling older adults with MCI and a fall-related hip fracture.
Interventions
