Objective: The objective of this study was to explore the effects of commonly used footwear in urban Pakistan on knee adduction moment (KAM), knee adduction angular impulse (KAAI) and biomechanical work at lower limb joints (both individually and collectively).
Methodology: Cinematographic gait analysis of 20 medial knee osteoarthritis patients (Kellgren-Lawrence Grade I and II, age: 55.48 ± 5.78 years; weight: 68.92 ± 9.61 kg, height: 1.62 ± 0.15m) was done, walking barefoot, with casual shoes, party shoes and traditional Pakistani sandals, at a walking speed of 1.2m/sec.
Results: Repeated measures ANOVA with Tukey corrections showed that all the shoes were found to be increasing first & second peaks external KAM and decreasing net joint work and total limb work significantly, at p < 0.05.
Conclusion: Effects of footwear were found to be majorly favouring knee osteoarthritis progression. This might be one of the risk factors of increased kOA rate in urban Pakistan.

Identifying the Primary Kinetic Factors Influencing the Anterior-Posterior Center of Mass Displacement in Barbell Squats: A Factor Regression Analysis.

Barbell squats are commonly used in strength training, but the anterior-posterior displacement of the Center of Mass (COM) may impair joint stability and increase injury risk. This study investigates the key factors influencing COM displacement during different squat modes.; Methods: This study recruited 15 male strength training enthusiasts, who performed 60% of their one-repetition maximum (1RM) in the Front Barbell Squat (FBS), High Bar Back Squat (HBBS), and Low Bar Back Squat (LBBS).

: Frontal knee malalignments are hallmarks of Achondroplasia (ACH), along with disproportional short stature. Typically, X-rays are used to assess them, but 3D gait analysis (3DGA) may additionally be used to evaluate dynamic knee function. The research questions were as follows: (1) What is the relationship between X-rays and 3DGA in ACH? (2) Do children with ACH have abnormal frontal knee kinematics and kinetics? (3) Are there aspects of 3DGA that relate to knee symptoms? : A total of 62 knees of 31 children with ACH (age: 11.

Purpose: People with unilateral transtibial amputation experienced a higher incidence of knee osteoarthritis due to abnormal movement patterns. This study aimed to explore alternations in muscle coordination to reduce mechanical burdens in their daily activities.
Methods: Five males with unilateral transtibial amputation were recruited.

Background: We aimed to synthesize the kinematics and kinetics during landing and walking/running tasks of ankle copers compared with patients with chronic ankle instability and controls.
Methods: We systematically searched PubMed, CINAHL, SPORTDiscus, and Web of Science. Tri-planar lower extremity biomechanics (joint angle and moment at maximum and initial contact, and joint displacement) were synthesized using standard mean difference and 95 % confidence intervals.

Background: Stair climbing tests are pivotal when assessing physical performance in knee osteoarthritis patients, yet the biomechanical strategies that underpin poor stair climbing ability are heterogeneously reported. Single step tasks emulate a step-by-step gait pattern, an approach associated with knee pain when stair climbing. The objective of this study is to analyse the biomechanics and electromyography activity of both the leading and trailing limbs during single Step-up and Down tasks in knee osteoarthritis patients.
