One hundred and fifty patients were recruited for this study. In one patient, baseline measurements were never taken due to an acute life-threatening hospitalization. Another patient was excluded due to a change in the study protocol, namely by adding the exclusion criteria of having a tracheotomy influencing the execution of the CTAR exercise. This leaves us with a total cohort of 148 patients. Patients, disease and treatment characteristics of the whole cohort and separate groups can be found in Table Patients, disease and treatment characteristics M = 63SD = 8.5Range = 41-86M = 63SD = 9.5Range = 41-86M = 63 SD = 7.9Range = 41-83M = 63 SD = 8.2Range = 45-80Gender FemaleMale 35 (24)113 (76)14 (29)35 (71)11 (22)38 (78)10 (20)40 (80)T classification1-23-475 (51)73 (49)25 (51)24 (49)22 (45)27 (55)28 (56)22 (44)N classification 012-37 (5)23 (15)118 (80)3 (6)7 (14)39 (80)3 (6)7 (14)39 (80)1 (2)9 (18)40 (80)Treatment RTCRTCRT with induction CT21 (14)102 (69)25 (17)6 (12)37 (76)6 (12)8 (16)32 (65)9 (19)7 (14)33 (66)10 (20)HPV status Positive Negative 76 (51)72 (49)24 (49)25 (51)23 (47)26 (53)29 (58)21 (42)M mean, SD standard deviation, RT radiotherapy, CRT chemoradiotherapy, CT chemotherapyPatients who immediately dropped out after baseline measures (paper group: Overview of drop-outsPaper group(n = 11)•Hospitalization with impossibility of continuing exercises (n = 2)•Refuse to further participation (n = 8)•Died (n = 1)App group (n = 13)•Acute hospitalization with impossibility of continuing exercises (n = 1) •Progressive disease (n = 1)•Refuse to further participation (n = 8)•Died (n = 3) Therapist group (n = 6) •Acute hospitalization with impossibility of continuing exercises (n = 1) •Refuse to further participation (n = 2)•COVID-19 infection for which applicable rules required stop of study contacts (n = 2) •Submental swelling (n = 1) *Excluded from the statistical analysis
