Impact of physical therapists’ instructions on function and the perception of post-dry needling soreness in mechanical cervical pain; a randomized clinical trial

BackgroundTo investigate the impact of physical therapists’ instructions on the perception of post dry needling (DN) soreness and function in patients with mechanical neck pain.MethodsSeventy-five patients with neck pain were randomly assigned to three groups: “positive” group (n = 25) received positive verbal input; “negative” group (n = 25) received negative verbal input, and control group (n = 25) did not receive any input about post-needling soreness. All three groups received DN of a trigger point in the upper trapezius muscle. The subjective pain experience, pressure pain threshold (PPT), and neck disability Index (NDI) were assessed before and after DN.ResultsPatients in all groups showed improvement in pain, PPT and NDI. There were no significant differences in pain (P = 0.41) and PPT (P = 0.68) in the positive and negative groups compared with the control group. Significant difference in function was seen with the NDI after DN of patients in the positive and negative groups compared with the control group (P = 0.011, standard error: 1.08–1.5).ConclusionConsidering that the power of our study may be too low to draw more definitive conclusions, DN appears to be an effective technique to improve pain and mechanical hyperalgesia. The experience of post-needling soreness does not appear to influence the outcome of DN on pain, PPT, and NDI. Post-needling soreness does not seem to be a limiting factor in achieving acceptable outcomes, especially when clinicians offer DN within a therapeutic emphasizing a positive patient response. This study questions whether any treatments need to be offered to patients receiving DN.     

Age and baseline values predict 12 and 24-month functional changes in type 2 SMA

The aim of this retrospective study was to establish the range of functional changes at 12 and 24-month in 267 type 2 Spinal Muscular Atrophy (SMA) patients with multiple assessments. We included 652 Hammersmith Functional Motor Scale Expanded (HFMSE) assessments at 12 month- and 305 at 24 month- intervals. The cohort was subdivided by functional level, Survival of Motor Neuron copy number and age. Stable scores (± 2 points) were found in 68% at 12 months and in 55% at 24 months. A decrease ≥2 points was found in 21% at 12 months and in 35% at 24 months. An increase ≥2 points was found in 11% at 12 months and 9.5% at 24 months. The risk of losing ≥2 points increased with age and HFMSE score at baseline both at 12 and 24-month. For each additional HFMSE point at baseline, the relative risk of a >2 point decline at 12 months increases by 5% before age 5 years (p = 0.023), by 8% between 5 and 13 (p<0.001) and by 26% after 13 years (p = 0.003). The combination of age and HFMSE scores at baseline increased the ability to predict progression in type 2 SMA.     

Automated morphometric magnetic resonance imaging analysis for the detection of periventricular nodular heterotopia

Purpose: To describe a novel magnetic resonance imaging (MRI) postprocessing technique for the detection of periventricular nodular heterotopia (PNH) and to evaluate its diagnostic value. The method is a further development of voxel‐based morphometric analysis with focus on a region of interest around the lateral ventricles to increase the sensitivity and specificity for automated detection of abnormally located gray matter in this area. Methods: T₁‐weighted MRI volume data sets were normalized and segmented in statistical parametric mapping (SPM 5 software), and the distribution of gray matter was compared to a normal database. As a new approach, individual masks derived from segmentation of the lateral ventricles were used to restrict the search for ectopic gray matter to the periventricular area. PNH were automatically detected by localizing the maximum deviation from the normal database in this area, provided that the z‐score exceeded a certain threshold. The optimal z‐score threshold for maximum sensitivity and specificity was determined by a receiver operating characteristic (ROC) curve analysis. The method was applied in 40 patients with PNH and 400 controls. Key Findings: PNH were detected in 37 of 40 patients, and false positives were found in 34 of 400 controls, amounting to 92.5% sensitivity and 91.5% specificity. In 17 of the patients in whom PNH could be identified, these lesions had been overlooked in the past, and in 8 patients even in the high‐resolution MRI subsequently used for postprocessing. Significance: The results suggest that automated morphometric MRI analysis with focus on ectopic gray matter in the periventricular areas facilitates the evaluation of MRI data and increases the sensitivity for the detection of PNH.     

Levodopa-carbidopa intestinal gel in advanced Parkinson's: Final results of the GLORIA registry

IntroductionThis registry evaluated the 24-month safety and efficacy of levodopa-carbidopa intestinal gel (LCIG) treatment in advanced Parkinson's disease (PD) patients under routine clinical care.MethodsMotor fluctuations, dyskinesia, non-motor symptoms, quality of life, and safety were evaluated. Observations were fully prospective for treatment-naïve patients (60% of patients) and partially retrospective for patients with ≤12 months of pre-treatment with LCIG (40% of patients). Hours of “On” and “Off” time were assessed with a modified version of the Unified Parkinson's Disease Rating Scale part IV items 32 and 39.ResultsOverall, 375 patients were enrolled by 75 movement disorder centers in 18 countries and 258 patients completed the registry. At 24 months LCIG treatment led to significant reductions from baseline in “Off” time (hours/day) (mean ± SD = −4.1 ± 3.5, P < 0.001), “On” time with dyskinesia (hours/day) (−1.1 ± 4.8, P = 0.006), Non-Motor Symptom Scale total (−16.7 ± 43.2, P < 0.001) and individual domains scores, and Parkinson's Disease Questionnaire-8 item total score (−7.1 ± 21.0, P < 0.001). Adverse events deemed to have a possible/probable causal relationship to treatment drug/device were reported in 194 (54%) patients; the most frequently reported were decreased weight (6.7%), device related infections (5.9%), device dislocations (4.8%), device issues (4.8%), and polyneuropathy (4.5%).ConclusionsLCIG treatment led to sustained improvements in motor fluctuations, non-motor symptoms particularly sleep/fatigue, mood/cognition and gastrointestinal domains, as well as quality of life in advanced PD patients over 24 months. Safety events were consistent with the established safety profile of LCIG.     

The Wheelchair Use Confidence Scale: Italian translation,adaptation, and validation of the short form

Objective: We developed an Italian version of the Wheelchair Use Confidence Scale for Manual Users-Short Form (WheelCon-M-I-short form) and examined its reliability and validity.

Methods: The original scale was translated from English to Italian using the “Translation and Cultural Adaptation of Patient Reported Outcomes Measures–Principles of Good Practice” guidelines. The WheelCon-M-I-short form was administered to experienced manual wheelchair users who had a variety of diagnoses. Its internal consistency and test–retest reliability were examined. Its concurrent validity was evaluated using Pearson correlation coefficients with the Italian version of the Wheelchair Outcome Measure (WhOM-I) and the Italian version of the Barthel index (BI).

Results: The WheelCon-M-I-short form was administered to 31 subjects. The mean?±?SD of the WheelCon-M-I-short form score was 7.5?±?1.9. All WheelCon-M-I-short form items were either identical or similar in meaning to the WheelCon-M-short form items. Cronbach’s α for the WheelCon-M-I-short form was 0.95 (p?p?p?p?Conclusions: The WheelCon-M-I-short form was found to be reliable and a valid outcome measure for assessing manual wheelchair confidence in the Italian population.

• Implication for Rehabilitation

• The WheelCon-M-I-short form is a valid outcome measure available for assessing wheelchair confidence, according to Bandura’s social cognitive theory, self-efficacy is a better predictor of future behavior than skill itself.

• Translation of the WheelCon-M-short form into the WheelCon-M-I-short form provides a new tool for Italian professionals.

• Clinicians now have a method to measure this invisible barrier to wheelchair use, and they will be able to make informed decisions when prescribing the use of manual wheelchairs and when training clients in their use.

• The WheelCon-M-I-short form also provides researchers with a tool in an important and relevant area of study for future research.

     

Neck pain in Iranian school teachers: Prevalence and risk factors

Neck pain (NP) is a common occupational health problem associated with a number of professions. Many studies indicate that NP is common among teachers, yet no published study was found to address the prevalence and risk factors of NP in Iranian school teachers. The purpose of the current study was to assess the prevalence and risk factors for NP among school teachers in Iran. A cross-sectional study was conducted on 586 randomly selected primary and high schools teachers from 22 schools in Tehran, Iran. Point, last month, last 6 months, annual, and lifetime prevalence rates of NP were 24%, 29%, 33%, 37%, and 43%, respectively. There was a significant association and increased prevalence of NP with a number of risk factors such as; being female, age, general health, length of employment, regular exercise and job satisfaction (P < 0.05 in all instances). Therefore, some individual and occupational factors may make conditions relevant for the development of NP among teachers.
