Postural Kyphosis, Shoulder Function, and Work Duration as Predictors of Shoulder Pain among Academic Staff: A Cross-Sectional Study

This cross-sectional study aimed to investigate the relationship between thoracic kyphosis posture, shoulder function, work duration, and the occurrence of shoulder pain among academic staff at Universitas Muhammadiyah Sidoarjo. A purposive sampling technique was employed to select 21 participants. Thoracic posture was measured using an inclinometer, shoulder function was assessed using the Constant-Murley Score, and muscle strength was evaluated with a hand dynamometer grip power test. The results revealed a significant correlation between thoracic kyphosis posture, shoulder function, work duration, and the occurrence of shoulder pain (r: 0.7±0.001, r: 0.6±0.003, r: 0.8±0.001, respectively). This study highlights the crucial role of posture, shoulder function, and work duration in contributing to shoulder pain among academic staff, emphasizing the need for ergonomic interventions and preventive measures to promote musculoskeletal health in this population.
 Highlights:
 
 Significant Correlation: The study establishes a strong and significant correlation between thoracic kyphosis posture, shoulder function, and work duration with the occurrence of shoulder pain among academic staff.
 Functional Impact: Shoulder function, as assessed by the Constant-Murley Score, plays a pivotal role in the development of shoulder pain, shedding light on the importance of maintaining optimal shoulder mobility and strength.

Predictors of shoulder pain in manual wheelchair users

BackgroundManual wheelchair users rely on their upper limbs to provide independent mobility, which leads to high muscular demand on their upper extremities and often results in shoulder pain and injury. However, the specific causes of shoulder pain are unknown. Previous work has shown that decreased shoulder muscle strength is predictive of shoulder pain onset, and others have analyzed joint kinematics and kinetics, propulsion technique and intra-individual variability for their relation to shoulder pathology. The purpose of this study was to determine in a longitudinal setting whether there are specific biomechanical measures that predict shoulder pain development in manual wheelchair users. MethodsAll participants were asymptomatic for shoulder pain and categorized into pain and no pain groups based on assessments at 18 and 36 months later. Shoulder strength, handrim and joint kinetics, kinematics, spatiotemporal measures, intra-individual standard deviations and coefficients of variation were evaluated as predictors of shoulder pain. FindingsIndividuals who developed shoulder pain had weaker shoulder adductor muscles, higher positive shoulder joint work during recovery, and less trunk flexion than those who did not develop pain. In addition, relative intra-individual variability was a better predictor of shoulder pain than absolute variability, however future work is needed to determine when increased versus decreased variability is more favorable for preventing shoulder pain. InterpretationThese predictors may provide insight into how to improve rehabilitation training and outcomes for manual wheelchair users and ultimately decrease their likelihood of developing shoulder pain and injuries.

High Frequency Ultrasound in Determining the Causes of Acute Shoulder Joint Pain

Shoulder ultrasonography is approved as the examination of choice for rotator cuff abnormality in many centers around the world since it is an inexpensive and safe tool for investigation of rotator cuff abnormalities. The goal of this study was to determine the ultrasound findings in patients with acute shoulder joint pain, and also to identify possible predictors of shoulder pain, as well as to compare the ultrasound diagnostic performance to that of MRI in such condition. A total of 65 (mean age 28 ± 1.2 years) consequential patients were recruited for a period of six months between July 2015 and June 2016 in this study. Collected data were confined on age, medical history, and clinical symptoms. Shoulder ultrasound was performed with a linear array transducer (10 - 15 MHz) connected to HI vision Avius ultrasound unit; Hitachi. MRI for the shoulder joint was performed in all cases to confirm the ultrasound results, using 1.5-T MRI system (Magnetom Espree); Siemens. Statistical analysis was completed using the standard Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA) version 20 for windows. Ultrasound manages to determine the causes of acute shoulder joint pain in 98% of the patients. Fitted achievement values for shoulder ultrasound in the diagnosis the causes of shoulder joint pain were 100% sensitivity and a range of 96% to 100% of accuracy. Ultrasound presents a high sensitivity and accuracy in diagnosis a wide spectrum of shoulder joint lesions, with a diagnostic performance near to that of MRI.

Predictors of Shoulder Pain and Disability Index (SPADI) and work status after 1 year in patients with subacromial shoulder pain

BackgroundShoulder pain is a common complaint in primary health care and has an unfavourable outcome in many patients. The objectives were to identify predictors for pain and disability (SPADI) and work status in patients with subacromial shoulder pain.MethodsSecondary analyses of data from a randomized clinical controlled trial were performed. Outcome measures were the absolute values of the combined Shoulder Pain and Disability Index (SPADI) and work status 1 year after treatment with supervised exercises (SE) or radial extracorporeal shockwave therapy (rESWT). Predictors of outcome were investigated using multiple linear regression (SPADI) and logistic regression (work status).Results104 patients were included. Low education (≤ 12 years), previous shoulder pain, and a high baseline SPADI score predicted poor results with these variables explaining 29.9% of the variance in SPADI score at 1 year. Low education and poor self-reported health status predicted a work status of "not working": Odds Ratio, OR = 4.3(95% CI (1.3 to 14.9)), p = 0.02 for education, and OR = 1.06 (95% CI (1.0 to 1.1)), p = 0.001 for self-reported health status, respectively. Adjustments for age, gender, and treatment group were performed, but did not change the results.ConclusionEducation was the most consistent predictor of pain and disability, and work status at 1 year follow-up. Also, baseline SPADI score, previous shoulder pain and self-reported health status predicted outcome.Trial registrationClinical trials NCT00653081

Predictors of shoulder pain and shoulder disability after one year in diabetic outpatients

To investigate factors associated with changes in shoulder pain and disability in diabetic outpatients over 1 yr. Cross-sectional study with 12-month follow-up in diabetic outpatients (n = 179) using the shoulder pain and disability index (SPADI) and SF-36 version 2. Patients with diabetes and shoulder pain or disability are more likely to be older and female. After 12 months of follow-up, one-quarter of participants without pre-existing symptoms at baseline developed clinically significant pain (28%) or disability (25%). Of the patients with pre-existing shoulder pain or disability, half reported clinically significant worsening (10 percentage points) in shoulder pain (58%) or disability (45%) over 12 months. Few patients demonstrated clinically significant improvement in pain (11%) or disability scores (19%). The remaining one-third of the patients reported no change in symptoms (30% pain; 35% disability). Increasing intensity of pain scores between baseline and 12 months was associated with older age, higher HbA(1c) and less pain at baseline. Increasing disability score between baseline and 12 months was associated with having had eye laser surgery, greater pain at baseline and less disability at baseline. Shoulder pain and disability are common, and persistent in adults with diabetes. Having higher HbA(1c) levels or having had treatment for retinopathy was associated with worsening shoulder pain and disability, confirming that glycaemic control and diabetic complications are associated with worsening shoulder pain or disability over 12 months of observation.

The prevalence and characteristics of shoulder pain after traumatic brain injury

Objective: To determine the prevalence and characteristics of shoulder pain in people with traumatic brain injury participating in inpatient rehabilitation and to compare the clinical presentation with that of people with stroke. Design: A prospective comparative study. Setting: Six metropolitan rehabilitation units. Subjects: Eighty-seven people with traumatic brain injury and 52 people with stroke took part in the study. Main measures: Assessment of shoulder pain, range of motion, strength and function was conducted on admission and, for the subjects with traumatic brain injury, at discharge if rehabilitation exceeded two weeks. Results: The prevalence of shoulder pain in people with traumatic brain injury was 62%, which was comparable with the 69% of subjects with stroke that experienced shoulder pain (odds ratio 0.72, 95% confidence interval 0.34 -1.5). Fracture in the shoulder complex and passive shoulder external rotation range of motion were the best predictors for shoulder pain after traumatic brain injury. This was different from the subjects with stroke for which the best predictors were passive shoulder flexion range of motion and length of acute hospital stay. Conclusion: There is a relatively high prevalence of shoulder pain after traumatic brain injury. Trauma to the shoulder complex contributes to shoulder pain after traumatic brain injury, making clinical presentation different from people with stroke. The findings support the need for greater attention in the management of shoulder pain after traumatic brain injury.

Shoulder Pain After Stroke

Shoulder pain is a well-known complication after stroke, but data on prevalence, predictors, and outcome in unselected stroke populations are limited. During a 1-year period, 416 first-ever stroke patients were included in the population-based Lund Stroke Register. After 4 months, 327 patients were followed up and 1 year later, the surviving 305 patients were followed up again. General status (National Institutes of Health Stroke Scale score) was registered at stroke onset. Shoulder pain intensity (visual analog scale, score 0 to 30=no-mild and 40 to 100=moderate-severe pain); arm motor function; restricted dressing and/or ambulating; and functional status (Barthel Index) were registered at both follow ups. Shoulder pain onset within 4 months after stroke was reported by 71 patients (22%). Among the 61 patients able to score the visual analog scale, 79% had moderate-severe pain. One year later, 8 of these 71 patients had died, 17 had no remaining pain, and 28 additional patients had developed shoulder pain since the first follow up. Lost or impaired arm motor function and high National Institutes of Health Stroke Scale score were predictors of shoulder pain. Shoulder pain restricted daily life often or constantly when dressing for 51%/31% and when ambulating for 29%/13% of the patients at 4 and 16 months, respectively. Almost one third of the 327 patients developed shoulder pain after stroke onset, a majority with moderate- severe pain. Shoulder pain restricts patients' daily life after stroke. The increased risk of shoulder pain for patients with impaired arm motor function and/or low general status needs close attention in poststroke care.
