Exercise to Reduce Mobility Disability and Prevent Falls After Fall-Related Leg or Pelvic Fracture: RESTORE Randomized Controlled Trial

Abstract

BACKGROUND: Disability and falls are common following fall-related lower limb and pelvic fractures. OBJECTIVE: To evaluate the impact of an exercise selfmanagement intervention on mobility-related disability and falls after lower limb or pelvic fracture. DESIGN: Randomized controlled trial. PARTICIPANTS: Three hundred thirty-six community dwellers aged 60+ years within 2 years of lower limb or pelvic fracture recruited from hospitals and community advertising. INTERVENTIONS: RESTORE (Recovery Exercises and STepping On afteR fracturE) intervention (individualized, physiotherapist-prescribed home program of weightbearing balance and strength exercises, fall prevention advice) versus usual care. MAIN MEASURES: Primary outcomes were mobilityrelated disability and rate of falls. KEY RESULTS: Primary outcomes were available for 80% of randomized participants. There were no significant between-group differences in mobility-related disability at 12 months measured by (a) Short Physical Performance Battery (continuous version, baseline-adjusted betweengroup difference 0.08, 95% CI − 0.01 to 0.17, p = 0.08, n = 273); (b) Activity Measure Post Acute Care score (0.18, 95% CI − 2.89 to 3.26, p = 0.91, n = 270); (c) Late Life Disability Instrument (1.37, 95% CI − 2.56 to 5.32, p = 0.49, n = 273); or in rate of falls over the 12-month study period (incidence rate ratio 0.96, 95% CI 0.69 to 1.34, n = 336, p = 0.83). Between-group differences favoring the intervention group were evident in some secondary outcomes: balance and mobility, fall risk (Physiological Profile Assessment tool), physical activity, mood, health and community outings, but these should be interpreted with caution due to risk of chance findings from multiple analyses. CONCLUSIONS: No statistically significant intervention impacts on mobility-related disability and falls were detected, but benefits were seen for secondary measures of balance and mobility, fall risk, physical activity, mood, health, and community outings.

Multifunctional Alginate Hydrogel Protects and Heals Skin Defects in Complex Clinical Situations

“…However, skin defects need to take a long time and are even difficult to heal. Functional exercises should be performed to prevent soft tissue adhesion and shortening during tendons, blood vessels, and nerves forming tissue connections within 2–4 weeks after anastomosis . Additionally, functional exercises can be performed immediately after stable repair in fractures to promote fracture healing and functional recovery.…”

Identification of risk factors for falls in postmenopausal women: a systematic review and meta-analysis

“…Postmenopausal women with a history of fractures and falls are more likely to fall again. In fact, the fracture history of elderly individuals, especially elderly women, is mostly a result of falling, making it a causal factor [42,43]. People who have suffered fractures tend to limit their daily activities and simultaneously experience negative emotions such as depression, anxiety and decreased self-confidence.…”

Bone loss induced by cancer treatments in breast and prostate cancer patients

“…The effect of exercise interventions seems less marked in patients who have already experienced fractures, although benefits were observed for measures of balance and mobility, fall risk, physical activity, mood, and community outings [111].…”
