A New Neurocognitive Interpretation of Shoulder Position Sense during Reaching: Unexpected Competence in the Measurement of Extracorporeal Space

Background. The position sense of the shoulder joint is important during reaching. Objective. To examine the existence of additional competence of the shoulder with regard to the ability to measure extracorporeal space, through a novel approach, using the shoulder proprioceptive rehabilitation tool (SPRT), during reaching. Design. Observational case-control study. Methods. We examined 50 subjects: 25 healthy and 25 with impingement syndrome with a mean age [years] of 64.52 +/− 6.98 and 68.36 +/− 6.54, respectively. Two parameters were evaluated using the SPRT: the integration of visual information and the proprioceptive afferents of the shoulder (Test 1) and the discriminative proprioceptive capacity of the shoulder, with the subject blindfolded (Test 2). These tasks assessed the spatial error (in centimeters) by the shoulder joint in reaching movements on the sagittal plane. Results. The shoulder had proprioceptive features that allowed it to memorize a reaching position and reproduce it (error of 1.22 cm to 1.55 cm in healthy subjects). This ability was lower in the impingement group, with a statistically significant difference compared to the healthy group (p < 0.05 by Mann–Whitney test). Conclusions. The shoulder has specific expertise in the measurement of the extracorporeal space during reaching movements that gradually decreases in impingement syndrome.

Tarsal tunnel syndrome: still more opinions than evidence. Status of the art.

Tarsal tunnel syndrome is an entrapment neuropathy of the posterior tibial nerve or its terminal branches within its fibro-osseous tunnel beneath the flexor retinaculum on the medial side of the ankle. The condition is frequently underdiagnosed leading to controversies regarding its epidemiology and to an intense debate in the literature. With the advent of nerve imaging techniques, the diagnostic confirmation and the etiological identification have become more accurate. However, management of this entrapment neuropathy remains challenging because of many intervention strategies but limited robust evidence. Uncertainties still exist about the best conservative treatment, timing of surgical intervention, and best surgical approach. In the attempt to clarify these aspects and to provide the reader some understanding of the status of the art, we have reviewed the published literature on this controversial condition.

Efficacy of extremely low-frequency magnetic field in fibromyalgia pain: A pilot study

The purpose of this pilot study was to determine the efficacy of an extremely low-frequency magnetic field (ELF-MF) in decreasing chronic pain in fibromyalgia (FM) patients. Thirty-seven females were recruited and randomized into two groups: one group was first exposed to systemic ELF-MF therapy (100 microtesla, 1 to 80 Hz) and then to sham therapy, and the other group received the opposite sequence of intervention. Pain, FM-related symptoms, and the ability to perform daily tasks were measured using the Visual Analog Scale, Fibromyalgia Impact Questionnaire (FIQ), Fibromyalgia Assessment Scale (FAS), and Health Assessment Questionnaire (HAQ) at baseline, end of first treatment cycle, beginning of second treatment cycle (after 1 mo washout), end of second treatment cycle, and end of 1 mo follow-up. ELF-MF treatment significantly reduced pain, which increased on cessation of therapy but remained significantly lower than baseline levels. Short-term benefits were also observed in FIQ, FAS, and HAQ scores, with less significant effects seen in the medium term. ELF-MF therapy can be recommended as part of a multimodal approach for mitigating pain in FM subjects and improving the efficacy of drug therapy or physiotherapy.

The efficacy of a preparatory phase of a touch-based approach in treating chronic low back pain: a randomized controlled trial

Background Massage therapy is an important element of rehabilitation in the treatment of chronic low back pain (CLBP). The objective of this study was to determine the relative efficacy of massage therapy between traditional massage and a new massage approach for CLBP. We also examined whether any reduction in pain was linked to interoceptive awareness and parasympathetic activation. Methods A single-blind, randomized, controlled trial of 51 patients who were allocated into a traditional massage therapy group (TMG; N=24, mean age: 50.54±9.13 years) or experimental massage therapy group (SMG; N=27, mean age: 50.77±6.80 years). The primary outcome was the reduction in pain per the visual analog scale (VAS); the secondary outcome measures were multidimensional pain intensity on the McGill Pain Questionnaire, pain-related disability per the Waddel Disability Index, interoceptive awareness per the Multidimensional Assessment of Interoceptive Awareness Questionnaire, quality of life per the Short Form - 12 Health Survey, and heart rate variability, expressed as the coherence ratio (CR) by photoplethysmography. The following outcome measures were assessed at baseline, at the end of the treatment program, and at the 3-month follow-up. The mean and standard deviation were calculated for continuous data. Mann–Whitney U test was used to perform between-group comparisons, Friedman’s analysis was used for data on the 3 assessment times in each group, and Spearman’s R coefficient was used to analyze correlations. Results Both approaches had a positive result on pain, an effect that was more acute in the SMG versus TMG for all pain scales, with better maintenance at the 3-month follow-up (VAS p=0.005 and p=0.098; Waddell Index p=0.034 and 0.044; McGill total p=0.000 and 0.003). In the SMG, CR scores were significant at baseline and at the end of the treatment program (p=0.000 and 0.002). Conclusion The new massage approach with a preparatory phase that is pleasant to the touch was more effective than the traditional approach for CLBP.

Extracorporeal Shockwave Therapy Improves Functional Outcomes of Adhesive Capsulitis of the Shoulder in Patients With Diabetes

Adhesive capsulitis of the shoulder (ACS) is the most prevalent musculoskeletal disorder of the upper extremity (1,2) among people with diabetes. ACS is characterized by intense shoulder pain with progressive limitation of joint mobility and functional disability, negative impact on the quality of life, and increased health care costs (3). In the population without diabetes, treatment options include supervised physical therapy, oral or intra-articular steroid injections, extracorporeal shockwave therapy (ESWT), and arthroscopic capsular release (4). Oral or intra-articular steroids lead to rapid pain relief and improved range of motion (ROM), although benefits from steroids may not be maintained beyond 6 weeks in patients with diabetes (5). In addition, steroids can significantly increase glucose levels, thus affecting glycemic control in patients with diabetes. Therefore , it would be preferable to avoid steroids and opt for alternative therapies in these individuals. In …

A Case of Double Anatomic Variation: Diagnostic Efficacy of Combination of Ultrasound and Neurophysiology

BACKGROUND The purpose of this paper is to underline that the association of physical examination, electrophysiology, and ultrasound was crucial in identifying the correct disease and atypical characteristics of its presentation, in turn, providing proper information for both surgical treatment and a rehabilitation program. Fibular nerve compression is a common finding in the adult population, and it is more frequent at the fibular head. The clinical picture may be characterized by motor and/or sensory deficits. The same symptoms may sometimes be suggestive of root impairment. CASE DESCRIPTION We report the case of a 39-year-old man who came to our laboratory with a diagnosis of multimetameric lumbosacral radiculopathy. The patient reported a history of ankle numbness and transient foot drop. Neurophysiologic examination showed peripheral axonal damage at tibialis anterior and lateral gastrocnemius muscles. A nerve ultrasound showed the presence of a conflict between a fibular exostosis and the fibular nerve. Furthermore, the fibular nerve presented an anatomic variation supplying the lateral gastrocnemius muscle. CONCLUSIONS Ultrasound was crucial in recognizing the cause of the atypical presentation and avoiding a misdiagnosis. Also, it allowed the identification of the appropriate treatment and rehabilitation, as well as preventing irreversible nerve damage. As a result, critical information was presented to the surgeon for surgical treatment.

Ultrasound Diagnosis of Postoperative Complications of Nerve Repair

BACKGROUND Peripheral nerve injuries often undergo surgical repair, but poor postoperative functional recovery is frequently observed. CASE DESCRIPTION We describe 4 cases of traumatic nerve lesions in whom postoperative recovery was prevented by complications such as detachment of nerve sutures or neuroma growth. To the best of our knowledge, no similar cases have been reported in literature so far. It is important to obtain an early diagnosis of such condition because it prevents recovery and delays reintervention, which should be performed before complete muscle denervation and atrophy. CONCLUSION Nerve ultrasound is a valuable tool in traumatic nerve injury and has proven to be useful in postoperative follow-up, especially in diagnosing surgical complications such as detachment of nerve direct sutures.

Ulnar neuropathy at wrist: entrapment at a very “congested” site

Ulnar tunnel syndrome indicates ulnar neuropathy at different sites within the wrist. Several classifications of ulnar tunnel syndrome are present in literature, based upon typical nerve anatomy. However, anatomical variations are not uncommon and can complicate assessment. The etiology is also complex, due to the numerous potential causes of entrapment. Clinical examination, neurophysiological testing, and imaging are all used to support the diagnosis. At present, many therapeutic approaches are available, ranging from observation to surgical management. Although ulnar neuropathy at the wrist has undergone extensive prior study, unresolved questions on diagnosis and treatment remain. In the current paper, we review relevant literature and present the current knowledge on ulnar tunnel syndrome.

Efficacy of dietary supplement with nutraceutical composed combined with extremely-low-frequency electromagnetic fields in carpal tunnel syndrome

[Purpose] The aim of this study was to investigate the clinical effects of a nutraceutical composed (Xinepa®) combined with extremely-low-frequency electromagnetic fields in the carpal tunnel syndrome. [Subjects and Methods] Thirty-one patients with carpal tunnel syndrome were randomized into group 1-A (N=16) (nutraceutical + extremely-low-frequency electromagnetic fields) and group 2-C (n=15) (placebo + extremely-low-frequency electromagnetic fields). The dietary supplement with nutraceutical was twice daily for one month in the 1-A group and both groups received extremely-low-frequency electromagnetic fields at the level of the carpal tunnel 3 times per week for 12 sessions. The Visual Analogue Scale for pain, the Symptoms Severity Scale and Functional Severity Scale of the Boston Carpal Tunnel Questionnaire were used at pre-treatment (T0), after the end of treatment (T1) and at 3 months post-treatment (T2). [Results] At T1 and T2 were not significant differences in outcome measures between the two groups. In group 1-A a significant improvement in the scales were observed at T1 and T2. In group 2-C it was observed only at T1. [Conclusion] Significant clinical effects from pre-treatment to the end of treatment were shown in both groups. Only in group 1-A they were maintained at 3 months post-treatment.
