Positive Wirkung von Hochtontherapie auf die funktionelle Kapazität von Patienten mit Post-COVID-Condition – eine Pilotstudie
Positive effect of high tone power therapy on the functional capacity of patients with Post-COVID condition – a pilot studyAuthors
Zusammenfassung
Hintergrund
Die Einschränkung der körperlichen Belastbarkeit sowie die Fatigue sind ausschlaggebende Symptome von Patienten mit Post-COVID-Condition (PCC). Als Therapieoptionen werden vorrangig symptomatische Ansätze genutzt. Die Hochtontherapie (HTT) könnte eine weitere Möglichkeit darstellen. In dieser Pilotstudie wird daher die Wirkung von HTT als Sonderform der Elektrotherapie auf die funktionelle Kapazität von Patienten mit PCC und Fatigue untersucht.
Materialien und Methode
Patienten mit PCC erhielten zehn HTT-Behandlungseinheiten von 60 Minuten Dauer. Vor Beginn sowie nach Abschluss der Behandlung wurde der One-minute-Sit-to-stand-Test (1-MSTST) sowie eine Assessmentbefragung zur gesundheitsbezogenen Lebensqualität (Short-Form-Health-Survey-12, SF-12), Schwere der PCC (Post-COVID-Score, PCS) sowie subjektiven Arbeitsfähigkeit (Frage des Work-Ability-Index‘, WAI) durchgeführt.
Ergebnisse
Die 22 behandelten Patienten (Median 52,0 Jahre (38,3; 63,3 Jahre)) konnten ihre Wiederholungszahlen im 1-MSTST signifikant steigern (T0 23,5; T1 35,5; p<0,001). Auch die gesundheitsbezogene Lebensqualität gemessen mit dem SF-12 stieg signifikant sowohl in der physischen (PSS) als auch in der mentalen (MSS) Summenskala an (PSS: p=0,031; MSS: p=0,009). Die Schwere der PCC sank signifikant (p=0,002), wenngleich von der Einstufung her weiterhin schwere PCC vorlagen. Die Einschätzung der subjektiven Arbeitsfähigkeit gemessen mit der ersten Frage des WAI stieg von 5,5 auf 8,5 Punkte von zehn möglichen.
Schlussfolgerungen
Die Ergebnisse deuten darauf hin, dass HTT einen positiven Einfluss auf die körperliche Belastbarkeit auf Patienten mit PCC haben kann. Kontrollierte Studien sowie die Erfassung möglicher weiterer Einflüsse durch begleitende physio- und ergotherapeutische Maßnahmen sind notwendig, um die Ergebnisse zu verifizieren.
Abstract
Objective
The limitation of physical resilience and fatigue are key symptoms of patients with post-COVID condition (PCC). Symptomatic approaches are primarily used as treatment options. High tone therapy (HTT) could be another option. This pilot study therefore investigates the effect of HTT as a special form of electrotherapy on the functional capacity of patients with PCC and fatigue.
Materials and methods
Patients with PCC received ten HTT treatment sessions lasting 60 minutes. The one-minute sit-to-stand test (1-MSTST) and assessment questionnaires on health-related quality of life (Short-Form-Health-Survey-12, SF-12), severity of PCC (Post-COVID score) and subjective work ability (Work Ability Index question, WAI) were carried out before the start and after the end of treatment.
Results
The 22 treated patients (median 52.0 years (38.3; 63.3 years)) were able to significantly increase the number of repetitions in the 1-MSTST (T0 23.5, T1 35.5; p<0.001). Health-related quality of life also increased significantly in both the physical (PSS) and mental (MSS) summary scales (PSS: p=0.031; MSS: p=0.009). The severity of PCC decreased significantly (p=0.002), even though PCC was still classified as severe. The assessment of subjective work ability measured with the first question of the WAI rose from 5.5 to 8.5 points out of a possible ten.
Conclusion
The results indicate that HTT can have a positive influence on the functional capacity of patients with PCC. Controlled studies are needed to verify the results, along with an assessment of possible influences of concomitant physiotherapy and occupational therapy.
