Knee osteoarthritis at the early stage: The four-week effect of lateral wedge insole on pain and risk of falls

Abstract

Background: Knee osteoarthritis (KOA) is associated with a decrease in function, increase in pain and risk of falls. Lateral wedge insole (LWI) is commonly prescribed in KOA to improve pain and function. Our study aimed to 1) evaluate the clinical symptoms and risk of falls in early KOA and compare with controls; 2) evaluate the immediate and four-week effect of LWI. Methods: A sample of 20 Persian dwelling individuals with early KOA and 19 matched controls were recruited. Pain with Visual Analogue Scale (VAS), Quality of life (QOL) with the knee injury and osteoarthritis outcome score, risk of falls with the Timed Up and Go (TUG) and static One-leg Balance (OLB) tests were assessed. The four-week effect of 5º LWI was considered for individuals with KOA. Independent t-test was done to report the between-group differences, and paired t-test was used to report the four-week effect of LWI. Results: At baseline, statistically significant higher scores for pain, lower scores for QOL, and higher risk of falls were observed in KOA compared to controls (p< 0.001). A significant statistical decrease was observed in pain, and risk of falls, and an increase in QOL in KOA after four-week effect of LWI compared to baseline (p< 0.001). Conclusion: People with early KOA showed higher pain and lower level of QOL that were associated with higher risk of falls. LWI may have the potential to improve clinical symptoms and reduce the risk of falls at the early stage of KOA.

Effects of foot orthoses on dynamic balance and basketball free-throw accuracy before and after physical fatigue

“…Although our studies did not measure the comfort perception variables, comfort perception has been received considerable interest by coaches and sports scientists. Foot orthoses would increase the perceived comfort and reduce the pain/discomfort (Esfandiari et al, 2018;Lucas-Cuevas et al, 2014;Mills et al, 2010). In rugby, the increase of comfort perception was related to higher actual performance (Kinchington et al, 2012) and lower incidence of injuries (Kinchington et al, 2011) in both competition and training.…”

The effect of a lateral wedge insole and a subtalar strap on gait parameters in knee osteoarthritis

“…Mean±SD of external knee adduction moment at early, mid, and late stance in 3 conditions: without insole, lateral wedge insole, and lateral wedge insole and a subtalar strap (n =17). 5 support ended to a protracted controversy (7,13,14,31). The possible explanations could be related to the variation among the sample of the studies or the interventions used in the studies.…”

“…However, customized arch support in LWI can improve pain, physical function, and foot function after 2 months (13) and EKAM in patients with KOA (31). The promising effect of LWI with an arch support with soft ethyl-vinyl acetate was also shown on pain and reduced risk of falls in patients with mild KOA compared to baseline (14). Therefore, LWI with an optimal arch support may be beneficial to patients with KOA.…”

“…Therefore, fixing the talus movement with a subtalar strap may increase the valgus angulation of the talus and augment the femorotibial angle change (11,12). Moreover, the effect of LWI can be increased if it is joined with the foot comfort, which is associated with concomitant use of longitudinal arch support (13,14). Although the augmented effect of LWI and a subtalar strap have been shown by reducing EKAM in KOA, the impact of using LWI with an arch support and a subtalar strap in reduction of EKAM has not yet been known (11,12).…”

Pain Among an Inpatient Complex Chronic Care Population of Residents with and without Missing Limbs

“…Although PLP and RLP are the most commonly reported types of pain among amputees, there is evidence to suggest that pain, not directly related to the surgical amputation, but possibly associated with the limb loss due to biomechanical sequelae, is also problematic among amputees. Musculoskeletal pain, 35,36 particularly upper and lower back pain, 5,11,14,15,[37][38][39][40][41][42] neck and shoulder pain, 5,[18][19][20][21] contra-lateral knee pain, 13,21 ipsilateral hip pain, 5,13 as well as other regional sites including knees, 21 leg and foot, buttocks and hips, arms and hands, abdomen, and head, 5 are also commonly reported, even on nonamputated sides. 21 Pain associated with a missing limb is also attributed with physical and psychosocial difficulties that can greatly interfere with an individual's quality of life.…”
