Background/Objectives: Musculoskeletal disorders of the lower back remain one of the leading causes of work-related health problems in occupations involving manual material handling. Passive industrial exoskeletons have gained increasing attention as...
Background/Objective: Gait symmetry in children is increasingly understood as a development-dependent continuum rather than a fixed endpoint. This narrative review extends that framework into a multidomain model of gait divergence in cerebral palsy (...
Background: The countermovement jump (CMJ) and the squat jump (SJ) are two common techniques for maximum-height jumping. The CMJ typically produces a greater jump height than the SJ; however, the mechanisms responsible for this difference in performa...
Background/Objectives: Mechanical shocks generated by the recoil of hand-held power screwdrivers are a significant biomechanical stressor for the operator’s hand–arm complex. Currently, vibration exposure is measured at the tool-handle le...
Background/Objectives: This study evaluated whether walking speed and backward-directed resistive force interact to systematically alter knee joint kinematics and activity of knee flexor and extensor muscles in healthy adults. Methods: Fourteen activ...
Background/Objectives: Change-of-direction (COD) movements represent a fundamental component of performance in multidirectional sports and constitute one of the primary mechanisms of knee injury. The biomechanical assessment of such movements has tra...
Background/Objectives: Human feeding behavior involves the use of various tools. However, the kinematic differences between commonly used utensils such as spoons and chopsticks remain insufficiently understood. The current study aimed to quantitative...
Background/Objectives: Maintaining a stationary manual wheelchair wheelie is a highly demanding dynamic postural control task that can be biomechanically modeled as an inverted pendulum. Although skilled wheelchair users employ a Proactive Balance St...
Objectives: This exploratory cross-sectional study examined the associations between rhythmic gymnastics training history and sagittal and frontal spinal alignment. Methods: Twenty-eight female volunteers were divided into a rhythmic gymnastics group...
Background/Objectives: Defecatory straining requires coordinated abdominal-wall and lumbopelvic muscle activity to generate propulsive pressure. This study investigated whether sitting posture alters ultrasound-derived transversus abdominis (TrA) con...
Background: Considerable variation exists in the proximal and distal fixture designs used in biomechanical testing of diaphyseal femoral implants. In most of them a load is applied to the femoral head, but muscle forces are rarely represented, so ben...
Background/Objectives: Carpal tunnel syndrome (CTS) is a prevalent neuropathy often associated with repetitive wrist movements, sustained wrist postures, and external compression. Although cycling offers numerous health benefits, prolonged handlebar...
Objective: This study investigated the effects of hopping speed and distance on ankle joint moments, power, and muscle activation during repeated lateral hopping tasks. Methods: Twelve trained male athletes involved in team sports performed repeated...
Background: Running-related injuries are a common issue among recreational runners and may affect training continuity and long-term participation. However, injury-associated factors remain unclear due to methodological heterogeneity and reliance on s...
Background/Objectives: This study investigated the effect of sprint intensity on spatiotemporal variables and joint kinematics during the maximal-velocity phase at each intensity level in experienced sprinters. Methods: Twenty experienced master spri...
Background/Objectives: The sit-to-stand task is widely used to assess functional performance after stroke; however, how upper-limb involvement is addressed methodologically during this transition remains unclear. This study aimed to map how upper-lim...
Background/Objectives: Lower-limb impairment can alter ankle-joint motion and reduce functional mobility during demanding locomotor tasks such as stair ascent and descent. This study presents the development and preliminary proof-of-concept evaluatio...
Background/Objectives: Decreases in hamstring isometric strength have been observed post-competition, but research has currently focused only on soccer players. Therefore, the purpose of the present study was to observe if acute reductions in isometr...
Background: Glenoid loosening is the primary cause of failure in anatomic Total Shoulder Arthroplasty (aTSA). Current ASTM standards evaluate loosening via standard orthogonal vectors using non-continuous monitoring, which offer limited insight into...
Background/Objectives: Surgical repair of the rotator cuff tendons can lead to unsatisfactory results and the requirement for further surgical treatment. Development of repair techniques is limited by a lack of appropriate functional pre-clinical tes...
Background: Injuries to the knee joint usually involve ligament or tendon structures. Most of these injuries are traumatic in origin. To better understand the structures and the associated failure mechanisms, a specific understanding of the biomechan...
Background/Objectives: Fracture of ceramic femoral heads in total hip arthroplasty is a rare but catastrophic complication requiring urgent revision surgery. Most finite element studies are limited to static loading and do not capture dynamic behavio...
Background: Team sports often involve high-intensity unilateral actions that can lead to neuromuscular asymmetries, increasing injury risk and reducing performance, particularly in young female athletes. Methods: This study quantified and compared in...
Background/Objectives: The morphology of the glenoid cavity is increasingly recognized as a key factor influencing joint mechanics and clinical outcomes, particularly in the context of shoulder instability. However, the specific effects of glenoid sh...
Background/Objectives: Hamstring tendon (HT) autografts are commonly used for anterior cruciate ligament reconstruction (ACLR), traditionally combining semitendinosus and gracilis (ST + GR) tendons to achieve adequate graft length and diameter. More...
Background/Objectives: Trabecular bone exhibits brittle behaviour governed by microscale deformation and damage, yet quantifying crack progression is difficult because classical fracture-mechanics approaches do not apply to architecturally discontinu...
Background/Objectives: Ankle dorsiflexion plays a fundamental role in gait stability, impact absorption, and the stance-to-swing transition, and its impairment is a major limitation in transtibial prostheses. This study proposes and evaluates a light...
Background/Objectives: The Dynamic Strength Index (DSI) has been proposed as an indicator of the ability to dynamically express maximum available strength; however, its practical significance remains unclear. This study examined the associations of t...
Background/Objectives: This study investigated kinetic performance, leg stiffness and gastrocnemius muscle (GM) activity during shod and barefoot two-legged hopping in female court athletes, while also assessing potential sport specialization-by-foot...
