Key characteristics of walking correlate with bone density in individuals with chronic stroke

Abstract: Abstract-Several recent studies of ambulatory stroke survivors have shown decreased bone mineral density (BMD) in the lower limbs and an elevated risk of hip fracture. Because bone mass is linked to skeletal loading, weight-bearing activities of daily living such as walking are considered critically important for maintenance of femoral BMD in ambulatory individuals. Little is known about the relationships between walking characteristics, skeletal loading, and bone maintenance in individuals who have experience… Show more

“…This is consistent with the findings by Worthen et al, who developed the Bone Density Index to quantify gait-related skeletal loading [48]. The computation of the Bone Density Index incorporates ground reaction force magnitude as well as the number of loading cycles per day.…”

“…Following a stroke, individuals can have a multitude of impairments that result in compromised functional status, low physical activity, reduced use of the paretic arm and leg, and consequently bone loss overall that is greater on the paretic side. In persons with stroke, BMD on the paretic side has been correlated with muscle strength [38][39], muscle atrophy [38,40], degree of motor recovery [41][42][43][44], cardiovascular fitness [40], ability to perform functional activities [42,[44][45], walking ability [46], weight-bearing ability [47], and amount of skeletal loading [48]. The nonparetic side may also sustain a certain degree of bone loss that is less pronounced when compared with the paretic side [46][47]49].…”
