Shoulder Osteoarthritis

Validity, reliability and responsiveness of a French translation of the Western Ontario Osteoarthritis of the Shoulder index (WOOS)

INTRODUCTION

While several general questionnaires can be used to evaluate shoulder conditions, very few tools specifically evaluate the impact of shoulder osteoarthritis. The Western Ontario Osteoarthritis of the Shoulder index (WOOS) is a patient-reported outcome measure with excellent psychometric properties intended for patients suffering from shoulder osteoarthritis. Unfortunately, there is no validated French version of this questionnaire.

OBJECTIVE

Produce a validated French version of the WOOS that is suitable for the Francophone populations of Europe and North America.

MATERIAL AND METHODS

A validated protocol was used to create a French version of the WOOS (WOOS-Fr). Included were patients whose first language was French, who could read French and who had shoulder osteoarthritis destined for treatment (surgical treatment=arthroplasty). The WOOS-Fr was compared to the Disability of the Arm, Shoulder and Hand-French translation (F-QuickDASH-D/S) to assess its validity. Reliability and responsiveness were also analyzed.

RESULTS

A French version of the WOOS (WOOS-Fr) was accepted by a multinational committee. The WOOS-Fr was validated in 71 French-speaking subjects. A strong positive correlation was found between the WOOS-Fr and the F-QuickDASH-D/S during the initial evaluation. The intra-class correlation (ICC) of the total WOOS-Fr score indicated good reliability between the initial WOOS and the 1-week WOOS (ICC: 0.84; 95% CI: [0.767; 0.896]; p-value: <0.001) in 57 patients. The responsiveness between the initial WOOS-Fr and at 1 year postoperative was high in the 36 operated patients (standardized mean response of 1.95).

DISCUSSION

A French translation of the WOOS questionnaire was created and validated for use in French-speaking populations. This questionnaire will make it easier to evaluate the psychometric results of patients with shoulder osteoarthritis in Francophone countries.

Shoulder osteoarthritis: A survey of current (2024) UK physiotherapy practice

BACKGROUND

Shoulder osteoarthritis can cause significant pain and disability. It is thought that the wider principles of osteoarthritis management can be applied in the management of people with shoulder osteoarthritis, but most prior research has been conducted with people experiencing osteoarthritis of the hip and knee. There is a paucity of evidence to guide the non-surgical management of shoulder osteoarthritis and limited understanding of current physiotherapy practice.

OBJECTIVE

We aimed to investigate the current treatment recommendations by physiotherapists in the UK for people with shoulder OA.

METHODS

An online survey using a clinical vignette was designed and distributed to UK registered physiotherapists with experience of managing people with shoulder osteoarthritis, via social media and professional networks. Descriptive statistics were used to analyse demographic and multiple-choice questions, and free text responses were summarised narratively.

RESULTS

114 respondents accessed the survey with 110 valid responses; 105 (95%) respondents would offer face-to-face consultations, with 89 (81%) respondents expecting to offer 2-4 appointments. 108 (98%) respondents would offer advice/education; 79 (72%) would offer weight management; 82 (75%) prescribed exercises to improve movement; and 101 (92%) offered exercises to increase strength. If a person lived with obesity or had a treatment preference, the majority of respondents would change their recommendations.

CONCLUSION

This is the first survey of NHS physiotherapy practice for people with shoulder osteoarthritis. The responses largely align with NICE guidelines; despite this alignment, it is not known whether such guideline-based care is acceptable to people with shoulder osteoarthritis or clinically effective.

The Effectiveness of an Exercise Program on Muscle Strength and Range of Motion on Upper Limbs, Functional Ability and Depression at Early Stage of Dementia

Background: Dementia involves the loss of cognitive abilities and represents a decline from the prior level of function, which impairs functional abilities in day-to-day life. The purpose of the present study is to examine the effectiveness of an exercise program on the muscle strength and range of motion of the upper limbs, the functional status, and the depression of elderly people with early stage dementia. Methods: The sample consisted of 60 elderly people with early stage dementia who were randomly divided into a control and an experimental group of 30 participants each. The experimental group received a 12-week Otago exercise program with 45 min duration of each session. The control group received usual care without doing exercise. The outcome measures of muscle strength and range of motion of the upper limbs, the functional status, and the depression were assessed by valid instruments and tests at the beginning and at the end of the intervention program. Repeated measures one-way ANOVA and Mann-Whitney tests examined the differences between the two groups at the end of the 12-week exercise program. Results: Statistically significant differences were found between the experimental and control groups in the entire outcome measures (functional ability F = 9.35 p < 0.05; muscle strength right hand F = 32.33, p < 0.05 left hand U = 95.50 p < 0.01; e.g., range of motion shoulder extension U = 104.00 p < 0.01), except depression. Conclusions: Both muscle strength and range of motion of the upper limbs, as well as the functional ability, were improved by the exercise program. Further research is needed to investigate the present results, in particular to explore the long-term cognitive, behavioral, and functional status outcomes of exercise in the early stages of dementia.

The Critical Shoulder Angle: A Significant Radiological Measure in Rotator Cuff vs. Glenohumeral Osteoarthritis in Chilean Patients-A Descriptive Cross-Sectional Study

Background: Shoulder pain is one of the most important musculoskeletal conditions affecting the upper extremities. Glenohumeral osteoarthritis (GHOA) and rotator cuff injuries (RCIs) are notable for their high prevalence. The critical shoulder angle (CSA) is a significant radiological measure for determining the diagnosis and progression of patients with these conditions. Although there are reports in the international literature about this measure, in our country, guideline values considering these two pathologies are unknown. Objective: Our objective was to assess patients diagnosed with GHOA and RCI using an AP X-ray view and the CSA. Methods: To conduct this, we identified differences between sexes and age categories. Fifty-nine adult patients with GHOA and RCI were included. CSA grades varied depending on the age category and type of injury evaluated. Results: Significant differences between the age ranges of 40 and 54 (p = 0.05), 55-69 (p = 0.001), and 70-84 (p = 0.017) were observed. Conclusions: Patients with RCI tended to be younger and have a higher CSA compared to those with GHOA. It is important to have more normative values and to continue monitoring the critical shoulder angle in these patients.

The Use of Linear Formulas to Estimate Glenoid Bone Loss in the Lebanese Population: A 3-Dimensional Computed Tomography Study

Background

Glenoid bone loss (GBL) is common in patients with shoulder instability and plays a major role in surgical decision-making. While a plethora of GBL estimation methods exist, all of which present specific challenges, recent studies have developed simple linear formulas estimating GBL based on glenoid height.

Purpose

To assess the correlation between glenoid height and width, and to develop specific formulas based on age and sex to calculate the native glenoid width in the Lebanese population.

Study Design

Cross-sectional study; Level of evidence, 3.

Methods

Computed tomography scans for 202 normal shoulders were extracted from our database. The glenoids were reconstructed in 3 dimensions and their width and height were measured. Glenoid width and height were compared between male and female groups. Correlation analysis was also performed on the width, height, age, and body mass index. Formulas estimating glenoid width were developed using regression analysis including all variables significantly influencing the model. Results were then compared with the values calculated using previously published formulas to determine the external validity when using linear formulas to estimate GBL.

Results

Significant differences were found between men and women. Regression analysis found that glenoid height and width strongly influenced the model, and that age showed a weak but significant correlation; therefore, the following 2 sex-specific formulas were developed: width (mm) = 6.1 + 0.51 ×height+ 0.03 ×age, and width (mm) = 4.55 + 0.51 ×height+ 0.03 ×age, in men and women, respectively. The values yielded from the formulas developed in this study and the true width significantly differed from those calculated from previous reports.

Conclusion

A strong correlation was found between glenoid height and width in a the Lebanese population and demonstrated that glenoid width can be accurately calculated based on the glenoid height and patient's age and sex using the following simplified formulas: width (mm) = 6 + 0.5 ×height+ 0.03 ×age, and width (mm) = 4.5 + 0.5 ×height+ 0.03 ×age, in men and women, respectively.

Colchicine Therapy for Glenohumeral Osteoarthritis: A Case Report

Osteoarthritis management primarily focuses on targeting pain. Conventional modalities for pain management include acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and intra-articular corticosteroid injections. However, these approaches may provide minimal pain relief and can be contraindicated for some patients, highlighting the ongoing need for alternative pain management. Colchicine, commonly used in the management of gout, has emerged as a potential option for pain management in osteoarthritis. There are implications of colchicine use for knee and hand osteoarthritis but remains inconclusive. In this context, we present a case of a 68-year-old diabetic woman with glenohumeral osteoarthritis and associated right shoulder pain. Due to minimal pain relief from previous treatments, the patient was given a combination trial of colchicine and acetaminophen for three months. After completion of this treatment, the patient experienced significant pain relief and improved functionality. The aim of this case is to highlight the efficacy of colchicine as a possible treatment option for managing shoulder pain in osteoarthritis.
