Diagnosing sarcopenia: Functional perspectives and a new algorithm from the ISarcoPRM.

Sarcopenia is an important public health problem, characterized by age-related loss of muscle mass and muscle function. It is a precursor of physical frailty, mobility limitation, and premature death. Muscle loss is mainly due to the loss of type II muscle fibres, and progressive loss of motor neurones is thought to be the primary underlying factor. Anterior thigh muscles undergo atrophy earlier, and the loss of anterior thigh muscle function may therefore be an antecedent finding. The aim of this review is to provide an in-depth (and holistic) neuromusculoskeletal approach to sarcopenia. In addition, under the umbrella of the International Society of Physical and Rehabilitation Medicine (ISPRM), a novel diagnostic algorithm is proposed, developed with the consensus of experts in the special interest group on sarcopenia (ISarcoPRM). The advantages of this algorithm over the others are: special caution concerning disorders related to the renin-angiotensin system at the case finding stage; emphasis on anterior thigh muscle mass and function loss; incorporation of ultrasound for the first time to measure the anterior thigh muscle; and addition of a chair stand test as a power/performance test to assess anterior thigh muscle function. Refining and testing the algorithm remains a priority for future research.

'Scientific Strabismus' or two related pandemics: coronavirus disease and vitamin D deficiency.

The WHO has announced the novel coronavirus disease (COVID-19) outbreak to be a global pandemic. The distribution of community outbreaks shows seasonal patterns along certain latitude, temperature and humidity, that is, similar to the behaviour of seasonal viral respiratory tract infections. COVID-19 displays significant spread in northern mid-latitude countries with an average temperature of 5­11°C and low humidity. Vitamin D deficiency has also been described as pandemic, especially in Europe. Regardless of age, ethnicity and latitude, recent data showed that 40 % of Europeans are vitamin D deficient (25-hydroxyvitamin D (25(OH)D) levels <50 nmol/l), and 13 % are severely deficient (25(OH)D < 30 nmol/l). A quadratic relationship was found between the prevalences of vitamin D deficiency in most commonly affected countries by COVID-19 and the latitudes. Vitamin D deficiency is more common in the subtropical and mid-latitude countries than the tropical and high-latitude countries. The most commonly affected countries with severe vitamin D deficiency are from the subtropical (Saudi Arabia 46 %; Qatar 46 %; Iran 33·4 %; Chile 26·4 %) and mid-latitude (France 27·3 %; Portugal 21·2 %; Austria 19·3 %) regions. Severe vitamin D deficiency was found to be nearly 0 % in some high-latitude countries (e.g. Norway, Finland, Sweden, Denmark and Netherlands). Accordingly, we would like to call attention to the possible association between severe vitamin D deficiency and mortality pertaining to COVID-19. Given its rare side effects and relatively wide safety, prophylactic vitamin D supplementation and/or food fortification might reasonably serve as a very convenient adjuvant therapy for these two worldwide public health problems alike.

EURO-MUSCULUS/USPRM Global Report on Musculoskeletal Ultrasound Publications.

The developments in technology have improved access to the use of musculoskeletal ultrasound (MSUS) in different clinical settings. Accordingly, MSUS has been applied to a wide range of musculoskeletal problems including inflammatory and degenerative diseases, sport injuries, and regional pain syndromes both for clinical practice and research. In this report, the authors aimed to globally examine the publications on MSUS among different specialties, countries, and topics. Sixteen reviewers under the umbrella of the European Musculoskeletal Ultrasonography Society Group and the Ultrasound Study Group of International Society of Physical and Rehabilitation Medicine have evaluated approximately 15,000 publications on MSUS. The authors believe that the results of this comparative analysis may provide a holistic snapshot with regard to the utility of MSUS, not only for clinicians/academicians but also for the industry. Accordingly, while aiming to further increase their awareness, this article would possibly guide future investments as well.

Bone marrow aspiration concentrate and platelet-rich plasma in the treatment of knee osteoarthritis: A report of three cases.

This paper presents the cases of 3 females with knee osteoarthritis. All 3 received a single bone marrow aspiration concentrate (BMAC) injection followed one month later by a platelet-rich plasma (PRP) injection. Compared with the baseline values, pain and functionality scores improved in all the patients. The aim of presenting these cases is to highlight that the combined use of intra-articular BMAC and PRP treatments may have positive effects on pain, functional status and quality of life in patients with knee osteoarthritis.

Training postural control and sitting in children with cerebral palsy: Kinesio taping vs. neuromuscular electrical stimulation.

OBJECTIVE: To elucidate the effects of Kinesio Taping (KT) in addition to neurodevelopmental therapy (NDT) on posture and sitting, and to compare the effects of KT and neuromuscular electrical stimulation (NMES). MATERIALS-METHODS: Seventy-five children were randomized into control, KT, and NMES groups. NDT was applied to all children 4 times a week for 4 weeks. In addition, KT and NMES were applied to KT and NMES groups, respectively. Sitting subset of Gross Motor Function Measure (GMFM) and kyphosis levels of the groups were analyzed by two way mixed ANOVA. RESULTS: GMFM and kyphosis values improved significantly in all groups (all p < 0.01), yet change levels were more prominent in the KT and NMES groups than the control group. Moreover, NMES group showed better improvement. CONCLUSION: KT or NMES application for four weeks in addition to NDT is effective on improving kyphosis and sitting. Besides, NMES is more effective than KT.

Effects of Kinesio Tape application to quadriceps muscles on isokinetic muscle strength, gait, and functional parameters in patients with stroke.

The aim of this study was to evaluate the effects of Kinesio Tape (KT) application to quadriceps muscles on isokinetic muscle strength, gait, and functional parameters in patients with stroke. Twenty-four patients were allocated into KT and control groups. All patients participated in the same conventional rehabilitation program 5 times/wk for 4 wk. In addition, KT was applied to quadriceps muscles bilaterally to the patients in the KT group. Compared with baseline, peak torque levels increased significantly in both groups (all p < 0.05). However, change levels were significantly higher in the KT group than the control group at 60 degrees/second angular velocity (AV) in extension (p = 0.04) and 60 and 180 degrees/second AV in flexion (both p = 0.02) on the paretic side. Moreover, the change levels were more prominent in the KT group at 60 and 180 degrees/second AV in extension (p = 0.03 and p = 0.04, respectively) on the nonparetic side. Gait, balance, mobility, and quality of life values improved significantly in both groups (all p < 0.05), yet the change levels between the groups did not reach significance (p > 0.05). KT application to quadriceps muscles in addition to conventional exercises for 4 wk is effective on isokinetic but not functional parameters.

Effects of neuromuscular electrical stimulation on the wrist and finger flexor spasticity and hand functions in cerebral palsy.

PURPOSE: To evaluate the effects of neuromuscular electrical stimulation on wrist range of motion, wrist and finger flexor spasticity, and hand functions in patients with unilateral cerebral palsy. METHOD: Twenty-four children with unilateral spastic cerebral palsy (14 boys and 10 girls) between the ages of 5 and 14 years were randomized into neuromuscular electrical stimulation and control groups. Conventional exercises were applied, and static volar wrist-hand orthosis was administered to all patients 5 days a week for 6 weeks. Additionally, 30-minute neuromuscular electrical stimulation sessions were applied to the wrist extensor muscles in the neuromuscular electrical stimulation group. Patients were evaluated by Zancolli Classification System, Manual Ability Classification System, and Abilhand-Kids Test. RESULTS: Compared with baseline, a significant increase was evident in active wrist extension angle at the fourth and sixth weeks in both groups (all P < 0.001), more prominent in the neuromuscular electrical stimulation group at the fourth and sixth weeks (P = 0.015 and P = 0.006, respectively). A decrease was observed in the spasticity values in the neuromuscular electrical stimulation group at the fourth and sixth weeks (P = 0.002 and P = 0.001, respectively) and in the control group only at the sixth week (P = 0.008). Abilhand-Kids values improved only in the neuromuscular electrical stimulation group (P < 0.001). CONCLUSION: Neuromuscular electrical stimulation application in addition to conventional treatments is effective in improving active wrist range of motion, spasticity, and hand functions in cerebral palsy.
