Shoulder Strength Requirements for Upper Limb Functional Tasks: Do Age and Rotator Cuff Tear Status Matter?

Anthony C. Santago II, Meghan E. Vidt, Xiaotong Li, Christopher J. Tuohy, Gary G. Poehling, Michael T. Freehill, and Katherine R. Saul

function due to age-related declines in strength. 2 , 3 Further, older adults employ compensatory kinematic strategies, such as decreasing their thoracohumeral elevation angle 4 when performing upper limb tasks. 4 – 7 These age-related declines can be exacerbated by a rotator cuff tear

Upper Limb Proprioceptive Acuity Assessment Based on Three-Dimensional Position Measurement Systems

Lin Li, Yanxia Li, Chang-hong Wu, and Hao Fu

upper limb can cause problems other than damage to the ligaments, labrum, or tendons; it may also affect neuromuscular control, resulting in a greater risk of joint disorders such as subacromial impingement syndrome ( Ettinger, Shapiro, & Karduna, 2017 ) and chronic rotator cuff pathology ( Anderson

Reliability of Shoulder Helical Axes During Intransitive and Transitive Upper Limb Tasks

Paola Adamo, Federico Temporiti, Martina Maffeis, Francesco Bolzoni, and Roberto Gatti

– 4 Previous studies found greater SC HAs dispersion during upper limb movements for the nondominant compared with dominant side as well as after muscle fatigue, showing an influence of neuromuscular control on HAs behavior. 5 Moreover, higher HAs’ dispersion was detected in older compared to young

Proprioceptive Acuity Assessment in Multiple Directions Across Multiple Joints in the Upper Limb

Kai-Qi Zhang, Yan-Xia Li, Na Lv, Qiang Ma, Shu-Jun Zhang, Xi Zhao, Kai Wang, Li Li, and Lin Li

; Winter et al., 2005 ). Activities of daily living usually require coordinated movement of multiple joints in the upper limb in multiple directions. Due to its significance in daily activities, proprioception in the upper limbs is especially crucial ( Hoseini et al., 2015 ). For example, when drinking

A Simple Method for Assessing Upper-Limb Force–Velocity Profile in Bench Press

Abderrahmane Rahmani, Pierre Samozino, Jean-Benoit Morin, and Baptiste Morel

Bench-press exercise is often used as a simple test to evaluate the upper-limb force, velocity, and power output. 1 – 3 These muscle parameters are usually determined using a force platform 4 , 5 or kinematic systems such as optical encoders 6 , 7 or linear transducers. 1 , 8 – 10 Although

An Experimental Method to Estimate Upper Limbs Inertial Parameters During Handcycling

Ghazaleh Azizpour, Matteo Lancini, Giovanni Incerti, Paolo Gaffurini, and Giovanni Legnani

. Some studies have focused on estimating elasticity, viscosity, and inertial contributions during a voluntary movement to obtain the upper limbs’ mechanical properties. 11 , 12 Namely, Kodek and Munih 3 and Kodek 13 moved the upper limb using a robot manipulator in a quasi-static situation to

Uncontrolled Manifold Analysis of the Effects of Different Fatigue Locations on Kinematic Coordination During a Repetitive Upper-Limb Task

Matthew Slopecki, Fariba Hasanbarani, Chen Yang, Christopher A. Bailey, and Julie N. Côté

Repetitive upper-limb movements are common in workplace tasks and have been associated with pain and musculoskeletal disorders ( Punnett & Wegman, 2004 ). Upper-limb and trunk musculoskeletal disorders were responsible for 53% of 240,682 lost-time claims in Canada in 2016 ( Statistics Canada CoC

Reliability of the ForceFrame With and Without a Fixed Upper-Limb Mold in Shoulder Rotation Strength Assessments Compared With Traditional Hand-Held Dynamometry

Jamon Couch, Marc Sayers, and Tania Pizzari

independent and custom-made uniaxial load cells. An attachable, prefabricated, fixed upper-limb mold can be used in conjunction with the ForceFrame to stabilize the shoulder while measuring muscle force. The reliability of the ForceFrame is high when measuring hip adduction strength (average intraclass
