“…The role of the upper limb in human postural control has previously been reported indirectly. It has been shown, for example, that axillary nerve blockage with anesthetics produces a 30% increase in body sway (Kjaergård et al, 1984 ), while immobilization of the upper limb with a sling reduce the performance in dynamic balance tests and increase the number of falls (Lui et al, 2013 ). The present study provides evidence that postural control and balance in adult subjects is impaired by upper limb dysfunction associated with the brachial plexus lesion.…”

“…Previous reports have shown the contribution of the upper limb to human postural control. Studies employing axillary nerve blockage with anesthetics (Kjaergård et al, 1984 ), upper limb immobilization (Coleman and Clifft, 2010 ; Lui et al, 2013 ) or fatiguing arm exercises (Douris et al, 2011 ) have shown that decreases in upper limb function negatively affect postural control and balance, as observed by increases in body sway or reduced performance in dynamic balance tests. Altered postural control and body alignment were also found in individuals who have undergone radical mastectomy, which usually results in lymphatic edemas, restriction of movement and strength loss in the arms (Rostkowska et al, 2006 ; Ciesla and Polom, 2010 ).…”

Objective: To investigate whether a sensorimotor deficit of the upper limb following a brachial plexus injury (BPI) affects the upright balance.Design: Eleven patients with a unilateral BPI and 11 healthy subjects were recruited. The balance assessment included the Berg Balance Scale (BBS), the number of feet touches on the ground while performing a 60 s single-leg stance and posturographic assessment (eyes open and feet placed hip-width apart during a single 60 s trial). The body weight distribution (BWD) between the legs was estimated from the center of pressure (COP) lateral position. The COP variability was quantified in the anterior-posterior and lateral directions.Results: BPI patients presented lower BBS scores (p = 0.048) and a higher frequency of feet touches during the single-leg stance (p = 0.042) compared with those of the healthy subjects. An asymmetric BWD toward the side opposite the affected arm was shown by 73% of BPI patients. Finally, higher COP variability was observed in BPI patients compared with healthy subjects for anterior-posterior (p = 0.020), but not for lateral direction (p = 0.818).Conclusions: This study demonstrates that upper limb sensorimotor deficits following BPI affect body balance, serving as a warning for the clinical community about the need to prevent and treat the secondary outcomes of this condition.

“…Posturography is typically used to evaluate the health status of patients suffering from musculoskeletal and neurological disorders, e.g. victims of accidents [11], [12], hemiparetic patients [13], people with cerebellar diseases [14], [15], Parkinson's disease [16]- [18] or disorders within the vestibular system [19]- [21]. The authors of this article, however, concentrate on its uses in the context of postural symmetry assessment of patients undergoing rehabilitation after total hip arthroplasty.…”

Postural Symmetry Evaluation Based on the Analysis of Temporary and Average CoP Displacements Registered During the Follow-Up Posturography

et al. 2019

This paper presents a method enabling a postural symmetry assessment based on the evaluation of similarity of temporary and average CoP (Center of Pressure) displacements registered in response to the clockwise and counterclockwise visual stimuli applied while performing the so-called follow-up posturography. This kind of visual feedback diagnostics is an intermediary between the static posturography and the dynamic posturography. One of its advantages is the ability to evaluate the dynamic performance of the human balance and posture control mechanisms using relatively inexpensive and popular static posturography platforms. The method presented in this paper was developed as a means for measuring the effectiveness of the rehabilitation program following total hip arthroplasty. The postural symmetry is, in this case, evaluated as the degree of mutual symmetry of the visually stimulated loading exerted on the left and right lower limbs. Usability of the method was verified in the group of 30 patients rehabilitated after total hip arthroplasty. The statistical analysis confirmed a significant growth of the values of the proposed symmetry measure over the period of the 21-day rehabilitation program (p < 0.001). There were, however, no significant correlations between that measure and the symmetry measures applied in the case of static posturography. The obtained results support the statement that the herein presented diagnostic approach enables the quantification of some other aspects of postural symmetry, namely the dynamic ones. This also corroborates the diagnostic value of the method discussed in this paper.

“…This combination of factors may lead to progressive failure at the bone implant interface, implant migration and fracture displacement. [1][2][3][4] Indications for surgery vary a great deal from study to study, and are often ill defined. Identification of risk factors for poor outcomes is important, including the identification of poor bone mineral density and the possibility of developing avascular necrosis.…”

Management of complex proximal humerus fractures in the elderly: what is the role of open reduction and internal fixation?

et al. 2019

View full text Add to dashboard Cite

The ultimate goal of management of proximal humeral fractures in the elderly patient is to get the patient independently mobile. This article will review the current literature regarding this cohort of patient. Recent Cochrane reviews and a large multicentre randomised study question the role of surgical intervention. Implant design is evolving rapidly, and many elderly patients now behave more like the younger patient. There remains little compelling evidence to guide decision-making for the complex proximal humeral fracture in the elderly, and the decision needs to be made on a case-by-case basis taking into account the patient's comorbidities, the fracture pattern and characteristics, the attending surgeon's skill sets, and the availability of equipment.
