BackgroundPatient-rated outcome measures (PROMs) are an important part of clinical decision-making in rehabilitation of patients with shoulder pain. The Disabilities of Arm, Shoulder and Hand (DASH) questionnaire was designed to measure physical disability and symptoms in patients with musculoskeletal disorders of the upper extremity and is one the most commonly used outcome measures for patients with shoulder pain. The purpose of this study was to investigate the reliability and validity of the Norwegian version of the DASH in patients with shoulder impingement syndrome.MethodsSixty-three patients diagnosed with shoulder impingement syndrome at an orthopaedic outpatient clinic were included in the study. Internal consistency of the DASH was evaluated by the Cronbach’s alpha and item-to-total correlations. Test-retest reliability was analyzed by the intraclass correlation coefficient (ICC) and limits of agreement (LoA) according to the Bland Altman method. Standard error of measurement (SEM) and minimally detectable change (MDC) were calculated for the total DASH score. Construct validity was evaluated by testing six a priori hypotheses for the Pearson’s correlation coefficient between the DASH and the Shoulder Pain and Disability Index (SPADI), the 36-item Short Form Health Survey (SF-36) and a Numeric Pain Rating Scale (NPRS).ResultsReliability: Cronbach’s alpha of the DASH was 0.93 and item-to-total correlations ranged from 0.36 to 0.81. ICC was 0.89. The 95 percent LoA was calculated to be between -11.9 and 14.1. SEM was 4.7 and MDC 13.1. Construct validity: Eighty-three percent of the a priori hypotheses of correlation were confirmed. The DASH showed a high positive correlation of 0.75 with the SPADI, a negative moderate correlation of -0.48 to -0.62 with physical functioning, bodily pain and physical component summary of the SF-36 and a moderate positive correlation of 0.58 with the NPRS. DASH correlated higher with the physical component summary than with the mental component summary of the SF-36.ConclusionsThe Norwegian version of the DASH is a reliable and valid outcome measure for patients with shoulder impingement syndrome.

The Disability of Arm, Shoulder and Hand (DASH) questionnaire is a tool for measuring physical function and symptoms of the upper extremity. Although widely used, it is not validated for rheumatoid arthritis (RA). In this study the DASH was validated for this patient group. In total, 102 patients participated in this study. For the validation, the questionnaires of the DASH, the Health Assessment Questionnaire (HAQ), the Medical Outcomes Study Short Form-36 (SF-36), and the Arthritis Impact Measurement Scale (AIMS2) were used. Patients were examined clinically before completing the questionnaires. Pain was scored by each patient using a visual analog scale (VAS). The Disease Activity Score (DAS28) was obtained and grip strength was measured. Reliability was tested by a second DASH questionnaire after 2 days. Validity was tested using a Pearson correlation analysis for the relevant domains of the questionnaires and for the clinical aspects. The reliability of the DASH was excellent (intraclass correlation coefficient 0.97). Internal consistency was strong (Cronbach's alpha 0.97). Validity was proven with excellent results for Pearson correlation with the relevant domains of the questionnaires: HAQ, r = 0.88; SF-36, r = 0.70; and AIMS2, r = 0.85. The clinical scores had a relatively low correlation with the DASH (DAS28, r = 0.42; and grip strength, r = 0.41-0.48), except for the VAS (r = 0.60-0.65). The DASH is a reliable and valid questionnaire in patients with RA. It can be used as a measurement tool of physical disability of the upper extremity.

Clinical rating systems in elbow research—a systematic review exploring trends and distributions of use

BACKGROUND CONTEXTDefining success in spine surgery lacks a standardized approach, and all existing concepts are based on registrations after surgery. PURPOSETo examine patients’ expectations before spine surgery assessed by a modified Oswestry Disability Index (ODI) and Numeric Rating Scale (NRS). The authors asked: how do the expectations align with actual outcomes and can a patient's individual expectations be used as a success criterion in itself? STUDY DESIGN /SETTINGProspective single-center study. PATIENT SAMPLEPatients scheduled for spine surgery at Akershus University Hospital (AHUS) were included in the study. They underwent 1 of 3 procedures: decompression for spinal stenosis, disc removal for lumbar disc herniation, or spinal fusion for degenerative disc disease. OUTCOME MEASURESModified and standard version of ODI and NRS (back and leg pain). METHODSPreoperatively, the patients were given a modified ODI and NRS questionnaire in which they were asked to register the minimum acceptable functional impairment and pain they anticipated to have postsurgery. The patients’ expectations were compared with 3-and 12-month follow-up data from the Norwegian Registry for Spine Surgery (NORspine) with ODI, NRS and Global Perceived Effect (GPE) scale. We used simple descriptive statistics. RESULTSA total of 93 patients completed the preop questionnaire. Of these, 65 responded to the 3-month follow-up and 53 at 12-month follow-up. The mean (95%CI) ODI before surgery was 38.3 (34.2–42.3), the mean (95% CI) preoperative NRS back pain was 6.34 (5.81–6.88), and leg pain was 6.67 (6.08–7.26). The patients expected a mean (95% CI) ODI of 10.5 (7.5–13.5), mean (95%CI) NRS back pain of 2.5 (2.1–3.0), and NRS leg pain of 1.8 (1.5–2.2). The actual clinical outcome after 12 months were a mean (95% CI) ODI of 21.7 (17.0–26.5), NRS back pain of 3.4 (2.8–4.1), and leg pain of 2.8 (2.0–3.5). Only 12 (30.8%) patients achieved their expected ODI, while 26 (65.0%) classified themselves as significantly better according to GPE. CONCLUSIONSPatients seem to have high expectations before spine surgery, and the expectations may exceed the clinical outcome. Only 30.8% had their ODI expectations met, but perceived benefit was higher. High expectations may be due to inadequate preoperative information and/or the unsuitability of ODI for capturing expectations.

Chronic low back pain (CLBP) is a common public health problem. Progressive loss of muscle strength leads to long-term chronic pain and disability. Yijinjing exercises, an ancient therapy dating back thousands of years, are widely used in China to treat low back pain. However, little is known about its benefits and scientific evidence for back extensor strength. This trial aimed to assess the efficacy of Yijinjing on disability and dorsal extensor strength in patients with CLBP. We present a randomized controlled study to evaluate the efficacy of the traditional Chinese exercise Yijinjing on disability and back extensor strength in patients with CLBP. This is a 2-arm, parallel-design, assessor-blinded, and analyst-blinded randomized controlled trial. The 106 participants with CLBP who were recruited will first receive basic traditional Chinese manual therapy to help relieve their physical discomfort. Second, they will be randomly divided into a Yijinjing group (n=53) and a control group with functional exercises (n=53) at a ratio of 1:1. The interventions for both groups will be carried out twice a week for 4 weeks. Patients in both groups will be followed up at 1 and 3 months after the intervention. The primary outcome is disability (measured by the Oswestry Disability Index). The secondary outcomes included pain intensity (assessed by the Numerical Rating Scale), data from isokinetic dynamometry, flexibility (assessed by the fingertip-to-floor test), mood (evaluated by the Pain Catastrophizing Scale and Fear Avoidance Beliefs Questionnaire), and quality of life (measured by the EQ-5D-5L). All adverse effects will be assessed using the Treatment Emerging Symptoms Scale, and data will be analyzed using an intention-to-treat analysis. The trial was funded in December 2023. The Institutional Ethics Committee of Yueyang Hospital of Integrative Medicine, Shanghai University of Traditional Chinese Medicine, approved this study. The first patient was enrolled in February 2024, and as of August 2024, a total of 106 participants have been recruited. Data analysis has not yet begun and is expected to be published in January 2025. The protocol has been registered with the Chinese Clinical Trial Registry (ChiCTR2400081105). If this trial proves effective, it will guide the setup of a randomized controlled trial to demonstrate whether traditional Chinese exercise Yijinjing improves disability in patients with CLBP and is more effective than usual stretching exercises.

Background:Low back pain (LBP) is ranked highest in terms of disability-adjusted life-years lived. Patient education and self-management have shown to play a crucial role in the overall pain management. However, the literature on the same with respect to Indian context is still lacking. The study was aimed to develop, validate and assess the acceptability and effectiveness of self-instructional educational module among Indian chronic LBP (CLBP) patients.Methods:A prospective single-arm open-label study was conducted in a pain clinic of a tertiary care public hospital in North India with 'Backcare booklet-self-instructional module (SIM)' as an intervention in patients with CLBP. SIM was developed with the intent to provide up-to-date evidence-based information in an easy understanding way to patients with CLBP. 132 patients were administered SIM with a single session of verbal explanation. Pain intensity (numeric rating scale [NRS]), disability, fear-avoidance belief Questionnaire (FABQ), quality of life (EQ5D) and knowledge level were assessed at baseline and after 3 months of intervention. Student's paired t-test and Chi-square test were used. Data were analysed using SPSS version 15.0.Results:120 patients successfully completed the 3 months' follow-up. Significant reductions were observed in pain intensity (76[12] vs 55 [15, P < 0.01); disability (51[14] vs 43 [10], P < 0.01); FABQ (46[12] vs 41 [10], P < 0.01); EQ5D (0.35 [0.27] vs 0.18 [0.26], P < 0.01).Conclusion:Backcare booklet as an intervention, along with usual pharmacological care is a cost-effective educational medium to promote self-management of CLBP in the clinical outpatient settings.

In recent years there has been an increased interest in pain neuroscience in physical therapy. Emerging pain neuroscience research has challenged prevailing models used to understand and treat pain, including the Cartesian model of pain and the pain gate. Focus has shifted to the brain's processing of a pain experience, the pain neuromatrix and more recently, cortical reorganisation of body maps. In turn, these emerging theories have catapulted new treatments, such as therapeutic neuroscience education (TNE) and graded motor imagery (GMI), to the forefront of treating people suffering from persistent spinal pain. In line with their increased use, both of these approaches have exponentially gathered increasing evidence to support their use. For example, various randomised controlled trials and systematic reviews have shown that teaching patients more about the biology and physiology of their pain experience leads to positive changes in pain, pain catastrophization, function, physical movement and healthcare utilisation. Graded motor imagery, in turn, has shown increasing evidence to help pain and disability in complex pain states such as complex regional pain syndrome (CRPS). Most research using TNE and GMI has focussed on chronic low back pain (CLBP) and CRPS and none of these advanced pain treatments have been trialled on the thoracic spine. This lack of research and writings in regards to the thoracic spine is not unique to pain science, but also in manual therapy. There are, however, very unique pain neuroscience issues that skilled manual therapists may find clinically meaningful when treating a patient struggling with persistent thoracic pain. Utilising the latest understanding of pain neuroscience, three key clinical chronic thoracic issues will be discussed – hypersensitisation of intercostal nerves, posterior primary rami nerves mimicking Cloward areas and mechanical and sensitisation issues of the spinal dura in the thoracic spine.

Prospective Study of the Functional Recovery After Surgery for Thoracic Outlet Syndrome

The purpose of this prospective, single site cohort quasi-experimental study was to determine the responsiveness of the numerical rating scale (NRS), Roland-Morris disability questionnaire (RMDQ), Oswestry disability index (ODI), pain self-efficacy questionnaire (PSEQ) and the patient-specific functional scale (PSFS) in order to determine which would best measure clinically meaningful change in a chronic low back pain (LBP) population. Several patient-based outcome instruments are currently used to measure treatment effect in the chronic LBP population. However, there is a lack of consensus on what constitutes a "successful" outcome, how an important improvement/deterioration has been defined and which outcome measure(s) best captures the effectiveness of therapeutic interventions for the chronic LBP population. Sixty-three consecutive patients with chronic LBP referred to a back exercise and education class participated in this study; 48 of the 63 patients had complete data. Five questionnaires were administered initially and after the 5-week back class intervention. Also at 5 weeks, patients completed a global impression of change as a reflection of meaningful change in patient status. Score changes in the five different questionnaires were subjected to both distribution- and anchor-based methods: standard error of measurement (SEM) and receiver operating characteristic (ROC) curves to define clinical improvement. From these methods, the minimal clinically important difference (MCID) defined as the smallest difference that patients and clinicians perceive to be worthwhile is presented for each instrument. Based on the SEM, a point score change of 2.4 in the NRS, 5 in the RMDQ, 17 in the ODI, 11 on the PSEQ, and 1.4 on the PSFS corresponded to the MCID. Based on ROC curve analysis, a point score change of 4 points for both the NRS and RMDQ, 8 points for the ODI, 9 points for the PSEQ and 2 points for the PSFS corresponded to the MCID. The ROC analysis demonstrated that both the PSEQ and PSFS are responsive to clinically important change over time. The NRS was found to be least responsive. The exact value of the MCID is not a fixed value and is dependent on the assessment method used to calculate the score change. Based on ROC curve analysis the PSFS and PSEQ were more responsive than the other scales in measuring change in patients with chronic LBP following participation in a back class programme. However, due to the small sample size, the lack of observed worsening of symptoms over time, the single centre and intervention studied these results which need to be interpreted with caution.

BackgroundChronic low back pain without disc herniation is common. Various modalities of treatments are utilized in managing this condition, including epidural injections. However, there is continued debate on the effectiveness, indications, and medical necessity of any treatment modality utilized for managing axial or discogenic pain, including epidural injections.MethodsA randomized, double-blind, actively controlled trial was conducted. The objective was to evaluate the ability to assess the effectiveness of caudal epidural injections of local anesthetic with or without steroids for managing chronic low back pain not caused by disc herniation, radiculitis, facet joints, or sacroiliac joints. A total of 120 patients were randomized to two groups; one group did not receive steroids (group 1) and the other group did (group 2). There were 60 patients in each group. The primary outcome measure was at least 50% improvement in Numeric Rating Scale and Oswestry Disability Index. Secondary outcome measures were employment status and opioid intake. These measures were assessed at 3, 6, 12, 18, and 24 months after treatment.ResultsSignificant pain relief and functional status improvement (primary outcome) defined as a 50% or more reduction in scores from baseline, were observed in 54% of patients in group 1 and 60% of patients in group 2 at 24 months. In contrast, 84% of patients in group 1 and 73% in group 2 saw significant pain relief and functional status improvement in the successful groups at 24 months.ConclusionCaudal epidural injections of local anesthetic with or without steroids are effective in patients with chronic axial low back pain of discogenic origin without facet joint pain, disc herniation, and/or radiculitis.

Hand grip strength is a critical indicator of upper extremity function, especially important in healthcare professions. Effective upper extremity function relies on proximal stability from the scapula and distal mobility from hand actions. This study aimed to examine the relationship between scapular dyskinesia and hand grip strength in healthcare students with smartphone addiction. A descriptive cross-sectional study was conducted with 63 students with smartphone addiction. Scapular dyskinesia was measured using Lateral Scapular Slide Test (LSST) at neutral, 45 and 90 degrees. Hand grip strength was measured using the Jamar Hydraulic hand dynamometer. The Short version of Smartphone Addiction Scale (SAS-SV) questionnaire assessed the severity of smartphone addiction, while the Disability of Arm, Shoulder and Hand (DASH) questionnaire evaluated the impact on upper extremity function. A negative correlation was found between LSST at 45degrees and hand grip strength. However, no significant correlation was observed between SAS-SV, DASH, and scapular dyskinesia. Findings of the present study report a negative association between scapular dyskinesia at 45 degrees of LSST and hand grip strength. This suggests greater the scapular dyskinesis, lower will be the hand grip strength.

We aimed to investigate the effect of hand osteoarthritis (HOA) on hand strength, dexterity, and upper extremity functional scores, as well as to determine the relation of radiological severity of HOA with these parameters. Sixty patients and 40 controls were enrolled in the study. The presence of hand pain, nodes, and tenderness in hand joints was determined. Grip and pinch strengths were measured by Jamar dynamometer and pinch meter, dexterity was assessed by Purdue pegboard test, and upper extremity function was determined by disabilities of arm, shoulder and hand (DASH) test. Hand radiographs were evaluated according to the Kallman grading scale. The mean age of the patients and control subjects were 58.9 ± 4.8 and 56.6 ± 5.8years, respectively. The level of hand pain and tenderness, and the number of nodes were significantly higher in the patient group than in control subjects. The mean grip and pinch strengths were lower in the patient group,: however, the difference was significant only in left lateral and left three chuck pinch. In hand dexterity, all scores except Purdue 1 were significantly lower in the patient group. In the functional evaluation DASH outcome, questionnaire scores of the patient and control groups were 48.3 ± 26.3 and 39.5 ± 23.5, respectively (p > 0.05). In the patient group, Kallman scores indicating radiological severity were found to be correlated with age, DASH scores, grip and pinch strengths, and Purdue scores (except Purdue assembly). Pain by visual analog scale was significantly higher in the patient group and correlated significantly with DASH scores. In patients with HOA, using standardized tests for evaluations may not be adequate. The determination of grip-pinch strength, dexterity and functional disability will lead to a clearer definition of the needs of the patients and will likely increase the gains from the rehabilitation programs.

Background:Loss of motion is a well-known complication after elbow trauma and in severe cases, arthrolysis of elbow is the procedure of choice. The posterior approach might have some advantages especially in post-traumatic patients who have undergone the same surgical approach in the past.Objectives:The aim of this study was to evaluate the short-term outcomes of elbow arthrolysis through posterior approach. Moreover, we assessed the effect of operation on the patients’ quality of life.Patients and Methods:During a retrospective-cohort study, the medical records of 14 patients (12 men, two women) whose range of movement had been limited post-traumatically and had undergone elbow arthrolysis with posterior approach were reviewed. Before intervention, the patients had a flexion less than 100 degrees or an extension lag of 30 degrees or more. For evaluation of the final outcomes, they were invited to participate in our study and the final range of motion, visual analogue score (VAS), disability of arm, shoulder and hand (DASH), Mayo elbow score (MES) and short form health survey (SF-36) scores were measured in the patients.Results:Mean age of the participants was 28.7 years. The interval from initial injury and arthrolysis was 16 months and the patients were followed for 14 months. The mean range of motion in patients before surgery was 35.8 degrees, which was increased to a mean of 108.9 after the surgery, indicating a 73.1 degrees improvement. The means of VAS, DASH, Mayo elbow and SF-36 scores in the patients were 1.6, 34, 68 and 43, respectively. A significant inverse correlation was found between the preoperative range of motion and final range of motion.Conclusions:According to our results, elbow arthrolysis through posterior approach could be an effective technique with low complications. Since the final range of motion improved significantly, it might be a valuable method in promoting the patients’ quality of life.

Distal radius fracture (DRF) is a common presentation to the ED. However, little is known about the long-term functional outcome of these patients following their initial management in the ED. In order to evaluate the long-term functional outcome of DRF, we collected the Disabilities of Arm, Shoulder and Hand (DASH) scores from the patients who attended our ED with DRF between January 2014 and June 2015. We divided the patients into two groups based on their overall management: (i) conservative group who did not have any surgical interventions; and (ii) open reduction internal fixation (ORIF) group who needed surgical interventions in the theatre. Multiple linear regression models were used to identify the statistically significant predictor variables. Out of the 229 patients whom we contacted, 128 patients responded. The response rate was 56%. The majority of the patients belonged to the conservative group (n = 87, 75%), while one-quarter of the patients were in the ORIF group (n = 29, 25%). DASH score was higher in the ORIF group (median = 12.1, 95% confidence interval 5.6-25) than the conservative group (median = 6, 95% confidence interval 1.7-16.4). This difference between the groups was statistically significant (unadjusted P = 0.017, Wilcoxon test). Multiple linear regression models revealed that the management group and age of the patients were significant predictors for DASH score. Conservative management had lower DASH scores signifying better functional outcomes. Further prospective multicentre studies may be suggested to assess the generalisability of the study.

Purpose In this literature review, functional outcomes such as Disability of Arm, Shoulder and Hand (DASH) score and the visual analog scale (VAS) of pain along with clinical outcomes such as range of movement and grip strength of treated distal radius fractures (DRF) accompanied with ulnar styloid fractures (USF) will be compared with those with isolated DRF. Materials and Methods We analyzed articles from MEDLINE, Embase, and CINAHL that met our predetermined inclusion and exclusion criteria as per the Preferred Reporting Items for Systematic Reviews and Meta-analysis statements. This resulted in the identification of 464 articles with 18 potentially eligible studies of which 6 were included at the full-text screening stage. The primary outcomes were wrist pain, range of motion, functional outcome and satisfaction, such as VAS, and the DASH questionnaire along with radiological assessment and incidence of complications. Results These studies involved 796 participants with DRF and 806 wrists with DRF; 444 (55%) of DRF had an associated USF. Three studies did not report any statistically significant difference in DASH scores between the DRF patients with or without USF. Two studies reported worse DASH scores in the group with associated USF. Wrist pain was reported to be statistically significantly worse in patients with associated USF in two studies. Grip strength did not exhibit a statistically significant difference in any groups in four studies. On assessing the range of motion of the wrist and forearm, only one study reported a statistically significant difference in flexion at 2 years follow-up, with less flexion in patients with USF. Conclusion This review suggests that there is no significant correlation between a USF and the functional and clinical outcomes of DRF treatment, albeit wrist pain and less flexion were reported in some studies to be associated with USF. There is a need for more robust evidence from large randomized controlled trials to specifically look at the effects of fixation versus nonfixation of USF on DRF, or large prospective cohort studies assessing DRF with and without USF, with a minimum of 12 months follow-up. Level of Evidence Level II-therapeutic.
