Awareness of limited joint mobility in type 2 diabetes in general practice in the Netherlands: an online questionnaire survey

BackgroundNext to the well-known micro- and macrovascular complications, type 2 diabetes mellitus (T2DM) is associated with musculoskeletal disorders of the upper extremities referred to as limited joint mobility (LJM), e.g. carpal tunnel syndrome (CTS) and adhesive capsulitis. Unrecognized and untreated LJM can lead to poor quality of life and non-compliance to diabetes treatment which aggravates LJM. Despite its reported higher prevalence in international prevalence studies, examination of the upper extremities is still no part of the regular diabetes mellitus (DM) check-ups. The primary aim of this study was therefore to evaluate the awareness of Dutch GPs and nurse practitioners concerning LJM. Secondary aims were to evaluate the current management of a patient with LJM, and to assess opinions regarding the question of who should screen for LJM if this is done in the near future.MethodsAn online survey was conducted among 390 general practitioners (GPs) and 245 nurse practitioners (NPs) of three diabetes care groups in The Netherlands to assess their awareness of the association between DM and LJM.ResultsMost GPs are not aware that LJM is a DM complication, with an unawareness for specific upper extremity disorders ranging from 59 to 73%. Of the NPs, 76% is not aware either. Only 41% of GPs would advise the most optimal treatment for diabetes patient with CTS. Finally, only 25% of the GPs believe that screening for LJM should be performed during the regular diabetes check-up compared to 63% of the NPs.ConclusionThe majority of GPs and NPs are not aware of LJM as a T2DM complication. In contrast to NPs, most GPs do not believe that screening for LJM should be performed during the regular diabetes check-up.</p

Shoulder muscle changes in patients with type 2 diabetes mellitus who have a painful shoulder:a quantitative muscle ultrasound study

BACKGROUND: It is assumed that in patients with diabetic neuropathy, muscle denervation can result in shoulder disorders. Muscle denervation will lead to changes in muscle architecture, which can be assessed by quantitative muscle ultrasound (QMUS). The aim was to investigate whether increased muscle echogenicity, as a sign of neuropathy, is more often present in patients with shoulder pain who have type 2 diabetes mellitus (T2DM) than in those without. METHODS: Sixty-six patients with T2DM and 23 patients without diabetes mellitus (DM) having shoulder pain were included. Quantitative muscle ultrasound images were obtained bilaterally from the biceps brachii, deltoid, and supra- and infraspinatus muscles. The mean echogenicity (muscle ultrasound grey value) was transformed into z-scores and compared to reference values obtained from 50 healthy participants. Associations between muscle echogenicity and clinical variables were explored. RESULTS: In painful shoulders of both patients with T2DM and patients without DM, mean echogenicity z-scores of all muscles were significantly increased compared to healthy controls. No significant differences in echogenicity between patients with T2DM and those without DM were found. In patients with T2DM, a distal symmetric polyneuropathy was significantly associated with increased echogenicity of all muscles except the infraspinatus muscle. CONCLUSIONS: These findings indicate that patients with painful shoulders, irrespective of having T2DM, seem to have abnormal shoulder muscles. Future studies are needed to elucidate whether neuropathy or other conditions lead to these muscle changes.

What Is the Diagnosis in Patients with Type 2 Diabetes Who Have a Painful Shoulder? Results from a Prospective Cross-Sectional Study

Background: Patients with diabetes mellitus have higher risk of developing shoulder pathology. However, only adhesive capsulitis is addressed in shoulder pain guidelines as a disorder associated with diabetes. Yet, patients with diabetes are at risk of having several other shoulder disorders, including focal neuropathy. Our aim was to quantify the presence of shoulder disorders using physical examination and ultrasound imaging in patients with type 2 diabetes (T2DM) suffering from shoulder pain in general practice. Methods: In this prospective cross-sectional study, patients with T2DM who had had a painful shoulder for at least four weeks were included. Patients filled out a questionnaire and underwent a physical examination of the shoulders and feet and ultrasound imaging of the shoulder. Results: A total of 66 patients were included, of whom 40.9% (n = 27) had bilateral complaints resulting in 93 symptomatic shoulders. Subacromial pain syndrome was most frequently diagnosed by physical examination (66.6%, 95% CI 51.6–72.0%; p &lt; 0.0001), while ultrasound imaging showed that subacromial disorders were statistically significantly the most prevalent (90.3%, 95% CI 81.9–95.2%). Only two patients (3%) were diagnosed with neuropathic shoulder pain. Conclusion: When choosing treatment, general practitioners should be aware that in patients with T2DM the subacromial region is most frequently affected

Prevalence of upper extremity musculoskeletal disorders in patients with type 2 diabetes in general practice

Background: One of the lesser recognized complications of diabetes mellitus are musculoskeletal (MSK) complications of the upper and lower extremity. No prevalence studies have been conducted in general practice. Thus, the aim of this study was to investigate the prevalence of upper extremity MSK disorders in patients with type 2 diabetes (T2DM) in the Netherlands. Methods: We conducted a cross-sectional study with two different approaches, namely a representative Dutch primary care medical database study and a questionnaire study among patients with T2DM. Results: In the database study, 2669 patients with T2DM and 2669 non-diabetes patients were included. MSK disorders were observed in 16.3% of patients with T2DM compared to 11.2% of non-diabetes patients (p < 0.001, OR 1.53, 95% CI 1.31, 1.80). In the questionnaire study, 200 patients with T2DM were included who reported a lifetime prevalence of painful upper extremity body sites for at least four weeks of 67.3%. Conclusion: We found that upper extremity MSK disorders have a high prevalence in Dutch patients with T2DM presenting in general practice. The prevalence ranges from 16% based on GP registered disorders and complaints to 67% based on self-reported diagnosis and pain. Early detection and treatment of these disorders may play a role in preventing the development of chronic MSK disorders
