A high variability in functional tests and activities used during the pulmonary rehabilitation has been observed in post-intensive care unit (ICU) patients, and the best battery of tests to adopt has not been described yet. We tested in patients admitted in a post-ICU Step Down Unit the ability to perform the more frequent functional volitional tests. The relations of each single volitional test with general disability and dyspnea at discharge were also evaluated. Ten volitional tests including: bedside spirometry test (ST: FEV1%, FVC%), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), Peak Expiratory Flow during Cough (PCEF), Quadriceps Muscle Strength (QMS), latissimus Dorsi and teres Major Strength (DMS), Brachial biceps Muscle Strength (BMS), effort tolerance measured by sit-to-stand test, Takahashi test and 6-Min Walking Test (6MWT), were evaluated in post-ICU patients at entry and discharge from in-hospital rehabilitation...

Inflammation is associated with glenohumeral arthritis and rotator cuff tendon tears. Epigenetically, miRNAs tightly regulate various genes involved in the inflammatory response. Alterations in the expression profile of miRNAs and the elucidation of their target genes with respect to the pathophysiology could improve the understanding of their regulatory role and therapeutic potential. Here, we screened key miRNAs that mediate inflammation and linked with JAK2/STAT3 pathway with respect to the coincidence of glenohumeral arthritis in patients suffering from rotator cuff injury (RCI)...

Distal biceps tendon ruptures are rare injuries that usually occur in middle-aged men. Most of these injuries are repaired acutely to restore preinjury function and strength. There is concern regarding the higher prevalence of certain complications with the double-incision technique. As such, the single-incision technique has also been studied to determine if it may produce superior safety and efficacy. In addition, the point of fixation may be created with either a rigid or a flexible reamer. The authors describe a technique that uses a single-incision cortical fixation achieved with a flexible reamer...

In the shot put, the athlete's muscles are responsible for generating the impulses to move the athlete and project the shot into the air. Information on phasic muscle activity is lacking for the glide shot put event and therefore important technical information for coaches is not currently available. This study provides an electromyography (EMG) analysis of the muscle activity of the legs during shot put. Fifteen right-handed Irish national level shot putters performed six maximum effort throws using the glide shot put technique...

In the context of lower (C8-T1) brachial plexus injury, transfer of the lateral antebrachial cutaneous nerve (LABCN) to the dorsal branch of the ulnar nerve (DBUN) with an interposed sural nerve graft has been proposed to restore sensitivity on the ulnar side of the hand. The purpose of this study was to assess the feasibility of performing this transfer directly - without interposition of a nerve graft - by intraneural dissection of the DBUN. An anatomical study was performed with 20 upper limbs from adult human cadavers...

INTRODUCTION: Upper brachial plexus injury in adults causes loss of elbow fl exion; when the primary nerve surgery has failed or the patient seeks treatment after 12 months of injury and pedicled muscle transfers are required. Most commonly, the latissimus dorsi or the Steindler flexorplasty is used. MATERIAL AND METHODS: We have transferred one of the heads of triceps muscle to restore the elbow flexion in such cases. In addition to return of elbow flexion, extension of elbow following surgery is retained...

The aim of this study was to compare the effect of a single session of a low-volume high-intensity interval exercise (HIIE) and a continuous exercise (CE) on the magnitude of delayed onset-muscle soreness (DOMS) in untrained healthy males. Fifteen participants (25.1±4.4 years) completed 2 experimental sessions in a randomized order: (a) low-volume HIIE: 10 x 60 s at 90% of maximal velocity (MV) interspersed with 60s of active recovery at 30% of MV; and (b) CE: 20 min at 60% of MV. Pressure-pain threshold (PPT), pressure-pain tolerance (PPTol) and perceived pain intensity (PPI) were assessed in the rectus femoris, biceps femoris and gastrocnemius before and 24 hours post-exercise...

In this study, we investigated the effects of increased kick frequency on the propelling efficiency and the muscular co-activation during underwater dolphin kick. Participants included eight female collegiate swimmers. The participants performed seven 15-m underwater dolphin kick swimming trials at different kick frequencies, which is 85, 90, 95, 100, 105, 110, and 115% of their maximum effort. The Froude (propelling) efficiency of the dolphin kick was calculated from the kinematic analysis. The surface electromyography was measured from six muscles (rectus abdominis, erector spinae, rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius)...

BACKGROUND: Minor events that occur in the workplace sometimes are evaluated with MRI, which may reveal age-related changes in the symptomatic body part. These age-related changes are often ascribed to the event. However, evidence of similar or worse pathophysiology in the contralateral joint would suggest that the symptoms might be new, but the pathophysiology is not. QUESTIONS/PURPOSES: Using a convenience sample of occupational injury claimants with bilateral MRI to evaluate unilateral knee or shoulder symptoms ascribed to a single event at work, we sought to determine whether MRI findings of the shoulder and knee are more often congruent or incongruent with new unilateral symptoms...

Javier Rodriguez-Falces
In monopolar electrode configuration, the shape of the motor unit potential (MUP) undergoes essential morphologic changes with increasing distance from the innervation zone. In particular, the rising phase of the MUP slows down and becomes longer as the electrode is moved further from the innervation zone. Based on this, it is hypothesized that the maximum slope of the rising phase of a monopolar MUP (SlopeMAX) would reach its highest value at the innervation zone. Herein, we sought to determine whether the location of the innervation zone coincides with the position in the muscle of the monopolar MUP with highest SlopeMAX and whether new criteria for the localization of the innervation region can be proposed based on the SlopeMAX of monopolar potentials...
