A Comparison of the Benefits of Sonography and Electrophysiologic Measurements as Predictors of Symptom Severity and Functional Status in Patients With Carpal Tunnel Syndrome

OBJECTIVES To clarify whether sonography or electrophysiologic testing is a better predictor of symptom severity and functional status in carpal tunnel syndrome (CTS) and to assess the diagnostic value of sonography in patients with idiopathic CTS. DESIGN Cross-sectional. SETTING University hospital physical medicine and rehabilitation clinic. PARTICIPANTS Thirty-four hands with CTS and 38 normative hands were evaluated. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The Boston Carpal Tunnel Questionnaire, which comprised symptom severity and functional status scale, was applied to CTS patients. Bilateral upper-extremity nerve conduction studies of median and ulnar nerves and sonographic imaging of the median nerve were performed in all participants. Sonographic evaluation was performed by a physician blinded to the physical and electrophysiologic findings of the subjects. RESULTS Cross-sectional areas (CSAs) of the median nerve at the carpal tunnel entrance and proximal carpal tunnel were 12.5+/-2.6 and 10.6+/-2.6 versus 15.6+/-4.2 and 11.5+/-3.2 in CTS patients versus controls, respectively. Increased CSA of the median nerve at the carpal tunnel entrance (P<.002) and at the proximal carpal tunnel (P<.000) were detected in the hands with CTS. Flattening ratios did not differ in a statistically significant manner between the groups (P>.05). The best predictor of symptom severity was median nerve sensory distal latency and that of functional status was median nerve motor distal latency. The optimum cutoff value for median nerve CSA was 11.2mm(2) at the carpal tunnel entrance and 11.9mm(2) at the proximal carpal tunnel. Sensitivity, specificity, and positive and negative predictive values at the proximal carpal tunnel (88%, 66%, 71%, 80%, respectively) were higher than those at the carpal tunnel entrance (68%, 62%, 65%, 66%, respectively). CONCLUSIONS The best predictors of symptom severity and functional status in idiopathic CTS seem to be the electrophysiologic assessments rather than sonographic measurements. On the other hand, sonography may be helpful in the diagnosis of idiopathic CTS.

Ultrasonographical evaluation of the Achilles’ tendon in psoriasis patients

Background  Psoriasis is a common dermatological disease with erythematous plaques where articular and extra articular findings (tenosynovitis and enthesitis) may well accompany. The aim of this current study was to evaluate the Achilles’ tendon of psoriasis patients with ultrasonography.

Quantification of the weakness and fatigue in thoracic outlet syndrome with isokinetic measurements

Objectives: Patients with thoracic outlet syndrome (TOS) complain of many subjective symptoms that are difficult to measure and quantify. In this study we have tried to assess the weakness (muscle strength) and fatigue (endurance) of these patients with an objective measurement method, isokinetic muscle testing. Methods: Twenty three TOS patients and 15 age matched healthy controls were enrolled in the study. Detailed histories of the patients were taken and the patients underwent complete physical examinations. Cervical radiographies, Doppler ultrasonography, electromyography, and isokinetic measurements were carried out. The isokinetic measurements were carried using the Biodex System 3 dynamometer during concentric shoulder flexions and extensions at velocities of 60°/s, 180°/s, and 240°/s. Results: Although the muscle strengths of both groups seemed to be similar, the fatigue ratios of TOS patients at 60°/s and 180°/s were found to be higher compared with those of healthy controls (p = 0.029, p = 0.007). Conclusions: TOS patients were found to have muscular performance similar to controls, but their upper extremities developed fatigue more easily than those of healthy individuals.

An underdiagnosed hip pathology: apropos of two cases with gluteus medius tendon tears

Until recently, gluteus medius tendon tears have been the sort of hip pathology that is relatively unknown in the realm of rheumatology. Their diagnosis can pose a serious challenge to physicians, despite diligence. In this report we summarize two relevant cases and put forward some hints for their evaluation. Magnetic resonance imaging is quite beneficial in demonstrating the pathology and ruling out other likely pathologies after a prompt physical examination. Physicians should exercise care and vigilance in order not to overlook these cases, in which prompt physical examination and radiological interventions remain a prerequisite in the diagnostic algorithm.

Effects of Different Strength Training on Muscle Architecture: Clinical and Ultrasonographic Evaluation in Knee Osteoarthritis

Different strengthening exercises are generally prescribed to overcome the undesirable effects of decreased muscular function on the osteoarthritic joint. Although a few studies have shown the effects of strengthening on the muscle structure in healthy individuals, the literature lacks relevant data concerning knee osteoarthritis.

Quantification of the Effects of Transcutaneous Electrical Nerve Stimulation With Functional Magnetic Resonance Imaging: A Double-Blind Randomized Placebo-Controlled Study

OBJECTIVE To evaluate the effects of transcutaneous electric nerve stimulation (TENS) by using functional magnetic resonance imaging (fMRI) in patients with carpal tunnel syndrome (CTS). DESIGN Randomized controlled trial. SETTINGS University medical center and an outpatient imaging center. PARTICIPANTS Female patients with CTS (n=20) were randomized into 2 groups receiving either TENS (n=10) or sham TENS (n=10). In both groups, an initial baseline fMRI session was performed via stimulating digits 2, 5, and 3 in turn, 1 scan run for each. TENS versus sham TENS treatment was given, and a repeat imaging was performed starting 20 minutes after the treatment as follows: second finger on the 20th minute, fifth finger on the 25th minute (ulnar nerve innervated control finger), and third finger on the 30th min. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Differences in fMRI activation between the 2 groups were evaluated. RESULTS Our results demonstrated that 20 to 25 minutes after TENS treatment-but not in the sham TENS group-a significant fMRI signal decrease for digit 2 (post-TENS vs baseline) was observed in the secondary somatosensory regions, ipsilateral primary motor cortex (M1), contralateral supplementary motor cortex (SMA), contralateral parahippocampal gyrus, contralateral lingual gyrus, and bilateral superior temporal gyrus. Measurements on the 25th to 30th minutes for digit 5 were similar between the groups, with presence of activities in areas other than generally activated regions because of painful stimuli. Thirty to 35 minutes after TENS treatment, a significant fMRI signal decrease for digit 3 was detected in the contralateral M1 and contralateral SMA only in the TENS group. CONCLUSIONS Our findings showed that TENS treatment significantly decreased the pain-related cortical activations caused by stimulation of the median nerve-innervated fingers up to 35 minutes after treatment.

Complex regional pain syndrome in thoracic outlet syndrome

We read with interest the article by Casey et al .1 Notwithstanding their substantial work, we have a few comments about their article. First of all, we wonder whether they performed any evaluations for coagulopathy in such a patient with severe thrombosis and endothelial damage. We also wonder why they delayed …

Musculoskeletal sonography use in physiatry: a single-center one-year analysis.

Özçakar L, Malas FÜ, Kara G, Kaymak B, Hasçelik Z: Musculoskeletal sonography use in physiatry: A single-center one-year analysis. Objective:To document the musculoskeletal ultrasonography experience in a physiatry clinic for 1 yr and to find out whether its use decreased time, cost, and radiation exposure with regard to musculoskeletal imaging. Design:All patients who underwent musculoskeletal ultrasonography examination (n = 309) in our physiatry department during the whole year of 2007 were enrolled. The same physiatrist, experienced in musculoskeletal ultrasonography, performed all of the evaluations by using 5–10 MHz and 8–16 MHz linear probes (Diasus Dynamic Imaging Ltd., Scotland, UK). At the end of the year, each patient was retrospectively considered on an individual basis, and the answers to the following three questions were recorded in case he/she had not been evaluated by musculoskeletal ultrasonography: (1) How long would the patient have waited (i.e., for further radiologic appointments)? (2) What would the extra cost have been? (3) What would the radiation exposure have been? Cumulative numbers were calculated for the whole year concerning time, cost, and radiation dose. Results:According to the calculations, the total waiting period was estimated as 7620 days if musculoskeletal ultrasonography had not been used for imaging. Similarly, the total cost and the radiation dose were estimated to be &U20AC;8128 (
