“…Control of toe clearance is increasingly more complex during sloped walking than level walking because the slope requires the foot to progress more vertically during the step [18]. In nondisabled adults, this is accomplished by increased ankle dorsiflexion during swing [19][20]. While people with amputation can adapt to uphill walking by altering hip and knee kinematics [21], the extent to which MTC, and thus the likelihood of tripping, is affected by inclined walking remains unknown.…”

Active dorsiflexing prostheses may reduce trip-related fall risk in people with transtibial amputation

Abstract-People with amputation are at increased risk of falling compared with age-matched, nondisabled individuals. This may partly reflect amputation-related changes to minimum toe clearance (MTC) that could increase the incidence of trips and fall risk. This study determined the contribution of an active dorsiflexing prosthesis to MTC. We hypothesized that regardless of speed or incline the active dorsiflexion qualities of the ProprioFoot would significantly increase MTC and decrease the likelihood of tripping. Eight people with transtibial amputation walked on a treadmill with their current foot at two grades and three velocities, then repeated the protocol after 4 wk of accommodation with the ProprioFoot. A mixed-model, repeated-measures analysis of variance was used to compare MTC. Curves representing the likelihood of tripping were derived from the MTC distributions and a multiple regression was used to determine the relative contributions of hip, knee, and ankle angles to MTC. Regardless of condition, MTC was approximately 70% larger with the ProprioFoot (p < 0.001) and the likelihood of tripping was reduced. Regression analysis revealed that MTC with the ProprioFoot was sensitive to all three angles, with sensitivity of hip and ankle being greater. Overall, the ProprioFoot may increase user safety by decreasing the likelihood of tripping and thus the pursuant likelihood of a fall.

“…Eccentric contraction of the quadriceps muscles requires more control and also tends to increase the compressive forces on the knee joint [26]. Stair climbing results in a significantly greater knee flexion angle, which in turn results in a greater knee extensor moment than level walking [27] and suggests why, during this short-term study, we found pain reduction in the activity that most challenged the knee musculature. While we found short-term significant reductions in all three components of the WOMAC, Pham et al found no changes in WOMAC pain, joint stiffness, and physical function subscales between those wearing full-length lateral-wedge insoles and those wearing neutral-wedge insoles in patients with medial femorotibial knee OA in a 2-year prospective randomized controlled study [11].…”

Abstract-This pilot study investigated whether lateral-wedge insoles inserted into shock-absorbing walking shoes altered joint pain, stiffness, and physical function in patients with symptomatic medial compartment knee osteoarthritis (OA). Twenty-eight subjects wore full-length lateral-wedge insoles with an incline of 4° in their walking shoes for 4 weeks. Pain, stiffness, and functional status were measured with the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index at baseline and 4 weeks postintervention. Significant improvements were observed in all three WOMAC subscales (pain, stiffness, and function). Pain scores were significantly reduced for the most challenging activity-stair climbing. Subjects wore insoles daily and tolerated them well. The results of this study indicated that lateral-wedge insoles inserted into shock-absorbing walking shoes are an effective treatment for medial compartment knee OA.

“…In this view, considering that water resistance in the presence of water turbulence increases as a log function of velocity, the muscular effort necessary to move the body increases as well 27 . Despite the importance of these muscles group to perform functional activities such as gait, sitting to standing from a chair 28 and ascending and descending stairs 29 , to our knowledge, there is no study that has assessed the effects of DWR on hip extensors and flexors. In this view, the current study found greater strength and power enhancement of the hip extensors and flexor muscles after DWR, which may contribute to improved functionality.…”

-Aims:The aim of the study was to determine the effects of deep-water running on muscle function and functionality in community-dwelling old women. Methods: Older women (n=19) were randomly assigned to one of the two groups: deep-water running (DWR: n=09, 64.33±4.24 years, 75.15±12.53 kg, 160.45±7.52 cm; or control group CG: n=10, 64.40±4.22 years, 74.46±12.39 kg, 158.88±5.48 cm). The DWR group carried out 18 weeks of deep-water running, twice/week 50 min sessions. Dynamic isokinetic strength for the lower limb and functionality was assessed before and after intervention. Results: DWR group increased peak torque, total work and average power of the knee and hip flexors and extensors. Additionally showed better performance on gait speed, timed up and go test, five-timessit-to-stand-test repetitions from a chair as well as the six-minute walk test. Conclusion: The deep-water running program was effective to improve muscle function and functionality.
