P Biomechanical analysis of shoulder joint movement by means of optimization methods

چکیده
This paper presents method for muscular force evaluation in shoulder joint based on optimization criteria of muscle force distribution. Multibody model of anatomical system was built with an assumption that skeletal system consists of rigid bodies. However, static and dynamic characteristics have been taken into account in the muscle description. This model was used to calculate the value of joint moments occurred during the realization of typical tasks for the system of shoulder joint. Then these moments were used for optimization purposes taking into account muscle cooperation criterion in order to calculate and compare force values and muscle actuation.

Purpose: Sub-acromial impingement syndrome [SIS] is one of the most common causes of shoulder pain, which affects shoulder joint proprioception. Closed kinetic chain [CKC] exercises with a Sling are more effective and safer than open kinetic chain [OKC] exercises. This study aimed to compare the efficiency of OKC and Sling exercises [TRX] on shoulder sense position joints in overhead athletes w...

متن کاملDirectional biases reveal utilization of arm's biomechanical properties for optimization of motor behavior.
Strategies used by the CNS to optimize arm movements in terms of speed, accuracy, and resistance to fatigue remain largely unknown. A hypothesis is studied that the CNS exploits biomechanical properties of multijoint limbs to increase efficiency of movement control. To test this notion, a novel free-stroke drawing task was used that instructs subjects to make straight strokes in as many differe...
