“…Such evidence could be provided by percutaneous bone pins, 26 or using radiographic 18 or magnetic resonance imaging (MRI) techniques. 2,23 The use of skin markers to explore the effects of foot orthoses on patellofemoral joint kinematics is ill advised. Reinschmidt et al 26 have documented that such analyses result in errors ranging from 21% to 70% for the 3 planes of knee motion compared with knee kinematics documented with bone pin markers.…”

Foot orthoses often are prescribed for patients with patellofemoral pain. The purpose of this clinical commentary is to review the theoretical and research basis that might support this intervention and to provide our own clinical experience in providing foot orthoses for these patients. Literature is reviewed regarding (1) the effects of foot orthoses on pain and function, (2) the relationship between foot and lower-extremity/patellofemoral joint mechanics, (3) the effects of foot orthoses on lower-extremity mechanics, and (4) the effects of foot orthoses on patellofemoral joint position. The literature and our own clinical experience suggest that patients with patellofemoral pain may benefit from foot orthoses if they also demonstrate signs of excessive foot pronation and/or a lower-extremity alignment profile that includes excessive lower-extremity internal rotation during weight bearing and increased Q angle. The mechanism for foot orthoses having a positive effect on pain and function for these patients may include (1) a reduction in internal rotation of the lower extremity; (2) a reduction in Q angle; (3) reduced laterally-directed soft tissue forces from the patellar tendon, the quadriceps tendon, and the iliotibial band; and (4) reduced patellofemoral contact pressures and altered patellofemoral contact pressure mapping. Foot orthoses may be a valuable adjunct to other intervention strategies for patients who present with the previously stated structural alignment profile.

“…However, accurate assessment of glenohumeral displacements remains difficult due to the lack of investigation tools that allow for direct tracking of glenohumeral motion in multiple functional positions. in vivo analysis of glenohumeral displacements in shoulder functional positions were presented in the literature using open magnetic resonance imaging (MRI) (Beaulieu et al, 1999;Graichen et al, 2000;Massimini et al, 2012;Sahara et al, 2007) or model-based fluoroscopy imaging systems (Bey et al, 2006;Boyer et al, 2008;Massimini et al, 2012;Nishinaka et al, 2008;Zhu et al, 2012). These methods first require a personalized 3D model reconstruction based on computed tomography (CT) scan (Bey et al, 2006;Nishinaka et al, 2008) or MRI (Boyer et al, 2008;Massimini et al, 2012;Zhu et al, 2012).…”

Recently, the three-dimensional (3D) reconstruction and registration method of the scapula and humeral head, based on sequences of low-dose biplane X-ray images, has been proposed for glenohumeral displacement assessment. This research aimed to evaluate the accuracy and reproducibility of this technique and to investigate its potential with a preliminary application comparing RC tear patients and asymptomatic volunteers. Accuracy was assessed using CT scan model registration on biplane X-ray images for five cadaveric shoulder specimens and showed differences ranging from 0.6 to 1.4 mm depending on the direction of interest. Intra-and interobserver reproducibility was assessed through two operators who repeated the reconstruction of five subjects three times, allowing defining 95% confidence interval ranging from ±1.8 to ±3.6 mm. Intraclass correlation coefficient varied between 0.84 and 0.98. Comparison between RC tear patients and asymptomatic volunteers showed differences of glenohumeral displacements, especially in the superoinferior direction when shoulder was abducted at 20°and 45°. This study thus assessed the accuracy of the low-dose 3D biplane X-ray reconstruction technique for glenohumeral displacement assessment and showed potential in biomechanical and clinical research.

“…These results indicated that muscular stabilization of the scapula with external loading increased in the healthy shoulders to provide a critical platform for upper extremity activity. Numerous other studies have also shown the humeral head moving to the glenoid center during elevation in healthy shoulders 7,9,13,14,[18][19][20][21] , in contrast, injured shoulders with diagnoses of cuff de ciency, instability, and trauma exhibit humeral translation away from the glenoid center 7, 9, 18-22 .…”

: An understanding of normal joint kinematics is essential to develop treatments that restore normal joint mechanics ; however, reports of kinematics during dynamic motion are rare. This study thus investigated glenohumeral GH translation in vivo during loaded and unloaded shoulder abduction. Nine healthy shoulders were studied from our patient cohort average age, 31 years . We created 3D models of the scapula and humerus using computed tomography CT images and recorded uoroscopic images during active abduction in neutral rotation in the plane of the scapula using a hand-held 3kg weight or no additional load. 3D motions were determined using model-based 3D-to-2D registration. Glenohumeral translation was determined by nding the location on the humeral head with the smallest separation from the plane of the glenoid. The humerus moved an average of 2 mm during arm abduction, from inferior to the center of the glenoid. There were no statistically signi cant differences between the unloaded and loaded conditions. Variability in humeral translation decreased with abduction using both 3-kg and 0-kg conditions, with signi cantly lower variability showing above a 70 GH abduction. We showed that humeral translation to the center of the glenoid maximizes joint congruency for optimal shoulder function and joint longevity. This data should lead to better strategies for shoulder injury prevention, enhanced rehabilitation, and improved surgical treatments.
