Zusammenfassung Hintergrund Der „Handscupe“ ist eine ergonomische medizinische Handauflage, welche zur Verbesserung von Handfunktion und Symptomen von Patient*innen mit rheumatischen Erkrankungen entwickelt wurde. Material und Methoden Das Ziel dieser prospektiven, explorativen Kohortenstudie zum Medizinprodukt „Handscupe“ war es, die klinische Relevanz für rheumatologische Patient*innen zu erfassen. Der „Handscupe“ wurde von 30 Patient*innen während eines dreiwöchigen Rehabilitationsprogramms verwendet. Folgende Parameter wurden dabei erfasst: objektive Maße der Handfunktion, patientenerfasste Parameter (standardisierte Fragebögen) und subjektive Zufriedenheit basierend auf einer visuellen Analogskala. Darüber hinaus wurden bei jedem Termin Laborparameter und die Krankheitsaktivität bestimmt. Ergebnisse Über alle untersuchten Krankheitsentitäten hinweg waren 97% der Patient*innen zufrieden mit der Anwendung des „Handscupe“, obwohl weder die Arthrosonographie noch die Krankheitsaktivitätsscore eindeutige Veränderungen zeigten. Die Mehrheit der Patient*innen zeigte eine Zunahme der Handgriffstärke, eine Schmerzlinderung, eine Verbesserung des allgemeinen Wohlbefindens und es wurde eine Verbesserung des Handscan-Scores festgestellt. Schlussfolgerung Diese explorative Studie zeigte einen klinisch relevanten Nutzen der Verwendung des „Handscupe“ bei Patient*innen mit rheumatischen Erkrankungen. Die klinische Umgebung in einer Rehabilitationsabteilung trug dazu bei, die tägliche Anwendung und Compliance sicherzustellen. Die beobachteten Effekte müssen jedoch aufgrund der gleichzeitig durchgeführten multi-professionellen Rehabilitationsmaßnahmen mit Vorsicht interpretiert werden. Daher ist eine bestätigende prospektive klinische Studie über die Wirkungen geplant.

“…This case–control study cross‐sectionally investigated the wrist torque of healthy volunteers (level of evidence III). The primary outcomes were wrist extension‐ and flexion torque, and its endurance; wrist extensor muscles are key element in considering the pathogenesis of lateral epicondylitis; the flexor muscles also contract together as antagonists during the gripping motion, 19 which is a pathophysiologically important component in LE.…”

Since eccentric contractions contribute to the development of tendinopathy, sex differences in wrist torque and endurance may be involved in the pathophysiology of lateral epicondylitis and its refractoriness. Therefore, the present study investigated sex differences in wrist torque and endurance. The wrist extension and flexion torques of the 100 wrists of 25 males and 25 females were measured. The following parameters were assessed: muscle strength at the starting-and end point for the measurement, Δ muscle strength, that is, the amount of a loss over time, and the muscle endurance ratio, that is, the decrease rate over time. Each parameter in males and females was statistically analyzed. In wrist extension, muscle strength at the starting point was 6.1 Nm for males and 3.3 Nm for females (p < 0.001); Δ Muscle strength was −0.052 Nm/s for males and −0.038 Nm/s for females (p = 0.036); The muscle endurance ratio was 99.1%/s for males and 98.8%/s for females (p = 0.015).In wrist flexion, muscle strength at the starting point and absolute value of Δ muscle strength were significantly larger in males than in females; No significant difference was observed in the muscle endurance ratio in wrist flexion between males and females. These results revealed sex differences in wrist torque and endurance. The muscle endurance ratio of the wrist extensors was lower in females than in males, which suggests that females need to exert more effort to maintain the wrist extension position under resistance. This may predispose the wrist extensor muscles in females to eccentric contractions.

“…They found statistically significant differences between the groups, finding that the HOA group used higher levels of muscle activation in daily tasks than the healthy group, and wrist extensors and flexors appeared to be equally affected. On the contrary, a recent work [16] compared the EMG signals of healthy individuals' forearm muscles to those of HOA patients, and found an activation deficit of the wrist's flexor and extensor muscles, even in initial HOA stages.…”

“…Despite [15] concluding that HOA patients require greater muscle activation for activities such as writing or cutting with scissors, ref. [16] indicates that this activation is lower. However, although in both studies the signal was normalized, in [15], they do not indicate the application of any filtering.…”

“…The equations provided in this work show that the digit flexors during the cylindrical grasp, thumb muscles during the oblique palmar grasp and wrist extensors and radial deviators during the intermediate power-precision grasp were much more significant for detecting HOA than the other muscles and grasps. The recent work [16] found that early-stage HOA may contribute to the activation deficit of the flexor and extensor muscles of the wrist. The results herein reiterate wrist extensors, along with thumb muscles and digit flexors, as possible muscle indicators for detecting HOA.…”

The early and objective detection of hand pathologies is a field that still requires more research. One of the main signs of hand osteoarthritis (HOA) is joint degeneration, which causes loss of strength, among other symptoms. HOA is usually diagnosed with imaging and radiography, but the disease is in an advanced stage when HOA is observable by these methods. Some authors suggest that muscle tissue changes seem to occur before joint degeneration. We propose recording muscular activity to look for indicators of these changes that might help in early diagnosis. Muscular activity is often measured using electromyography (EMG), which consists of recording electrical muscle activity. The aim of this study is to study whether different EMG characteristics (zero crossing, wavelength, mean absolute value, muscle activity) via collection of forearm and hand EMG signals are feasible alternatives to the existing methods of detecting HOA patients’ hand function. We used surface EMG to measure the electrical activity of the dominant hand’s forearm muscles with 22 healthy subjects and 20 HOA patients performing maximum force during six representative grasp types (the most commonly used in ADLs). The EMG characteristics were used to identify discriminant functions to detect HOA. The results show that forearm muscles are significantly affected by HOA in EMG terms, with very high success rates (between 93.3% and 100%) in the discriminant analyses, which suggest that EMG can be used as a preliminary step towards confirmation with current HOA diagnostic techniques. Digit flexors during cylindrical grasp, thumb muscles during oblique palmar grasp, and wrist extensors and radial deviators during the intermediate power–precision grasp are good candidates to help detect HOA.
