“…According to Resende et al (2011), if individuals with KOA stayed in the support phase longer, it is possible that the prolonged effect of a minor overload would be close to the short effect of an intense joint stress, i.e., the protective neuromuscular response may cause pain and joint damage. Thus, when the strategy of the movement changes due to pain or reduced capacity to stabilize a segment, joint overloads and early fatigue occur [13].…”

“…This loss of strength is more significant than that presented by the healthy population in the same age group that reaches 30 to 40% of maximum capacity [12]. The quadriceps weakness observed in this population can decrease the shock absorption capacity during walking, leading to accentuated symptoms and, consequently, gait pattern alteration as a strategy to minimize pain and maintain functionality [9,13].…”

“…Weakness of this muscle group may be responsible for increased metabolic expenditure during functional activities, which limits the intensity and duration of these tasks [14,15]. Therefore, reduced ability to generate quadriceps strength, characteristic in patients with KOA, can negatively affect gait pattern, with a greater probability of becoming dependent on daily tasks, which leads to a decrease in quality of life and an increase in public expenditures to care services for this population [12,13].…”

Background: Osteoarthritis is the most prevalent rheumatic disease in the population and is characterized by limitation of main functional activities of daily living, as the gait. Muscle strength is a variable that may be related to performance in daily tasks.Therefore, we to analyze the gait pattern in individuals with knee osteoarthritis (KOA) and to determine associations of gait variables with the level of muscle strength of knee extensors. Methods: Sixty-seven female volunteers divided into 2 groups, a KOA group (KOAG, n = 36, 66.69 ± 7.69 years) and control (n = 31, 63.68 ± 6.97 years), participated in the study. The volunteers walked on a 10-m platform at their usual gait speed, using 2 pressure sensors positioned at the base of the hallux and calcaneus. The mean step time, support and double support times, swing time and gait speed were calculated. The evaluation of the quadriceps isometric torque was performed in an extensor chair, with hip and knee flexion at 90°. The procedure consisted of three maximal contractions of knee extension. Peak torque was determined by the highest torque value obtained after the onset of muscle contraction. For statistical analysis, one-way ANOVA and Pearson's correlation were used, with p < 0.05. Results: The KOAG had a 54.76% longer support time, a 13% longer step time (p < 0.001), a 30% decrease in swing time (p < 0.001) and a 10.7% decrease in gait speed (p = 0.001) compared with controls. The quadriceps isometric torque was 34% (p = 0.001) lower in the KOAG. There was a correlation between kinematic variables and quadriceps torque. Conclusion: Weakness of the quadriceps muscle in women with KOA influences gait pattern, resulting in reduced speed associated with a shorter swing time and longer support time.

“…18 An inverse association has also been found between pelvic motion and knee extension strength. 17 Reduced knee extension strength, a known predictor for functional decline, 19 is a common finding in knee OA, 20 particularly the ability to produce maximal voluntary eccentric force. 21 Reduced function in daily life activities in persons with knee OA has been identified with use of a plethora of questionnaires.…”

Background: Difficulty descending stairs is common in persons with knee osteoarthritis (OA). Clinically, it is important to know if and how this is explained by objectively measured difficulty to descend stairs, muscle weakness, pain, fear of movement, or knee joint status.Objective: To identify the potential of these factors to explain self-reported difficulty descending stairs. Design: Cross sectional, case-control. Setting: Hospital outpatient and physiotherapy clinic. Participants: Twenty-eight men and women with knee OA (age 62.2 SD 5.9 years) and 31 controls (age 50.0 SD 8.5 years). Intervention: Not applicable. Main outcome measures: Using multivariate statistics, group comparisons were made for lower extremity kinematics (incorporating hip, knee, and ankle angles) and stance time in stair descent and lower extremity muscle strength. Then, a stepwise linear regression analysis was performed within the OA group to explain self-reported difficulties in stair descent where pain, kinesiophobia, radiographic signs, and outcomes that differed from controls for stair-descent kinematics and muscle strength were independent variables. Results: Multivariate statistics showed that the OA group displayed different allover lower extremity kinematics (F 8,42 = 2.44 p = .029, η 2 = 0.32) and a longer stance time (F 3,50 = 6.46; p = .001, η 2 = 0.28) in stair descent and lower muscle strength (F 7,47 = 2.39; p = .035, η 2 = 0.26) compared to controls. Regression analysis within the OA group to explain self-rated difficulties to descend stairs showed that the strongest association with kinesiophobia (ß = 0.607, p = .001) that combined with pain last week and radiographic signs explained almost 100% (ß = 0.972). Stair descent kinematics and strength variables that differed between groups did not explain self-rated difficulties to descend stairs. Conclusion: Kinesiophobia and pain rather than stair-descent kinematics and reduced muscle-strength explained self-rated difficulties in stair descent in the OA group.
