Implications of Walking Aid Selection for Nonweightbearing Ambulation on Stance Limb Plantar Force, Walking Speed, Perceived Exertion, and Device Preference in Healthy Adults 50 Years of Age and Older.

BACKGROUND: Young adults often tolerate the increased energy expenditure, coordination, and stance limb discomfort associated with walking aids for nonweightbearing ambulation. Adults aged ≥50 years may not have the same tolerance. Therefore, the objective of this study was to determine how walking aid selection affects stance limb plantar force, walking speed, perceived exertion, and device preference in adults aged ≥50 years. METHODS: A prospective randomized crossover study was performed using healthy adults, aged ≥50 years, with no use of walking aids within 5 years. Participants walked 200 m in 4 randomized conditions: single nonweightbearing ambulation using crutches, a walker, a wheeled knee walker, and unaided walking. An in-shoe sensor measured stance limb plantar force, a stopwatch timed each walk, perceived exertion was reported using the BORG CR-10 scale, and device preference was identified. RESULTS: Twenty-one participants (7 male; age: 56 ± 5 years; BMI: 26.6 ±1.9) showed stance limb plantar force was lowest when using a wheeled knee walker (P < .001). Walking speed was similar in unaided and wheeled knee walker conditions (1.41 and 1.31 m/s), but slower with crutches or a walker (42%-68%, P < .001). Perceived exertion was similar in unaided and wheeled knee walker conditions (1.6 and 2.8), but higher with crutches or a walker (5.7 and 6.1, P < .001). Most (20/21) participants preferred the wheeled knee walker. CONCLUSIONS: Using a wheeled knee walker for nonweightbearing ambulation reduced stance limb plantar force, maintained unaided walking speed and perceived exertion, and was preferred to crutches or a walker. LEVEL OF EVIDENCE: Level II, comparative study.

Understanding Physiotherapists' Intention to Counsel Clients with Chronic Pain on Exercise: A Focus on Psychosocial Factors.

Purpose: Twenty percent of Canadians experience chronic pain. Exercise is an effective management strategy, yet participation levels are low. Physiotherapists can be key to counselling clients to engage in long-term unsupervised exercise. Yet, investigations that identify psychosocial factors related to physiotherapists' intention to counsel are lacking. The purpose of this study was to examine whether physiotherapists' knowledge of chronic pain, beliefs about pain, and self-efficacy to counsel on exercise predicted their intention to counsel clients with chronic pain on exercise. Method: Practicing physiotherapists (N = 64) completed an online survey that assessed their knowledge of chronic pain, beliefs about pain, self-efficacy, and intention to counsel. A two-step hierarchical multiple regression predicted intention. Step 1 controlled for years of practice, and Step 2 included study variables significantly correlated with intention. Results: Beliefs about pain (r = -0.35, p < 0.01) and self-efficacy (r = 0.69, p < 0.01) were significantly correlated with intention. The overall regression model was significant, F 3,60 = 18.73; p < 0.001. Self-efficacy was the sole significant predictor, t 60 = 5.71, p < 0.0001, sr 2 = 28%. Conclusions: Self-efficacy may facilitate physiotherapists' intention to counsel on exercise for chronic pain. If shown to be a causal factor, interventions that target a change in physiotherapists' self-efficacy should be pursued.

Objectif : une proportion de 20 % des Canadiens souffre de douleurs chroniques. L'exercice est une stratégie de prise en charge efficace, mais les taux de participation sont faibles. Les physiothérapeutes peuvent jouer un rôle déterminant dans les conseils aux clients afin qu'ils suivent un programme d'exercices non supervisés à long terme. Il n'existe pourtant pas d'études pour déterminer les facteurs psychosociaux liés à l'intention de conseiller des physiothérapeutes. La présente étude visait à examiner si les connaissances des physiothérapeutes à l'égard de la douleur chronique, leurs convictions au sujet de la douleur et leur auto-efficacité à donner des conseils sur l'exercice étaient prédictives de leur intention de donner des conseils sur l'exercice à leurs clients ayant des douleurs chroniques. Méthodologie : des physiothérapeutes en exercice (n = 64) ont rempli un sondage en ligne évaluant leurs connaissances sur la douleur chronique, leurs convictions au sujet de la douleur, leur auto-efficacité et leur intention de conseiller. Une analyse de régression hiérarchique multiple en deux étapes a prédit leur intention. L'étape 1 assurait un contrôle par rapport aux années d'exercice et l'étape 2 incluait des variables ayant une corrélation significative avec l'intention. Résultats : les convictions sur la douleur (r = ­0,35, p < 0,01) et l'auto-efficacité (r = 0,69, p < 0,01) avaient une corrélation significative avec l'intention. Le modèle de régression globale était substantiel : F 3,60 = 18,73; p < 0,001. L'auto-efficacité était le seul prédicteur significatif : t 60 = 5,71, p < 0,0001, sr 2 = 28 %. Conclusion : l'auto-efficacité peut faciliter l'intention des physiothérapeutes de donner des conseils sur l'exercice en cas de douleur chronique. S'il est démontré qu'il s'agit d'un facteur causal, il faudrait prévoir des interventions afin de changer l'auto-efficacité des physiothérapeutes.
