The primary aim of this study was to investigate the immediate effects of partial versus complete head rotation and chin tuck on pharyngeal swallowing pressures and durations in the pharynx and UES of normal, healthy adults. Ten individuals (3 men and 7 women; age range 54-76 years) served as participants. Solid-state intraluminal manometry was performed with the participants in the upright position while performing swallows with the head in the normal position, head rotated (partial and complete), chin tucked, and chin down. A cervical range of motion (CROM) inclinometer was used to accurately measure the degree of head rotation and chin tuck. The CROM inclinometer has not been used before so this is the first study to our knowledge to quantify degree of head rotation and chin tuck. Manometric data derived from these healthy participants indicate both partial and complete head rotations can increase the duration of UES relaxation and decrease UES residual pressure. Chin tuck may be effective in increasing durations in the upper pharynx. Partial chin tuck (chin down) decreases UES residual pressure. Complete head rotation and chin tuck provide more overall benefit than partial maneuvers. However, for patients with limited head and neck mobility, partial posture changes impact the pharynx in similar ways and may provide clinically meaningful benefits. Additional research on patient populations is warranted. HubMed – rehab

Submaximal exercise parameters are associated with an increased risk of hospitalization in patients with heart failure, but the implication in patients with Fontan circulation remains unknown. We investigated the prognostic value of these parameters in a Fontan cohort, in whom maximal exercise effort is often limited.Fifty-two Fontan patients received cardiopulmonary exercise tests at least 12 months after Fontan completion. We evaluated 2 maximal parameters (peak oxygen consumption (VO2) and heart rate reserve (HRR)) and 2 submaximal parameters (oxygen uptake efficiency slope (OUES) and minute ventilation (VE) to carbon dioxide elimination (VCO2) slope).The peak VO2 and OUES was 58.0 ± 11.2% and 56.6 ± 14.5 % of the age-and sex-related predicted values. In the subsequent follow-up (median 22.7 months), 11 patients (21%, including one death) exhibited cardiac morbidity, defined as cardiac-related hospitalization. Time-dependent receiver operating characteristic curve analysis demonstrated that only submaximal parameters were related to 2-year cardiac morbidity (area under the curve for OUES 0.781, P = 0.018; for VE/VCO2 slope 0.714, P = 0.04), even in the subgroup achieved maximal exercise effort. The optimal threshold value for OUES was 45%, and for the VE/VCO2 slope, it was 37. Furthermore, the OUES conveyed independent prognostic information beyond resting oxygen saturation and a history of heart failure or protein-losing enteropathy.Submaximal exercise parameters provide superior prognostic information to maximal exercise data for predicting cardiac morbidity in Fontan patients. Moreover, the association between the OUES and cardiac morbidity is independent of relevant baseline clinical information. HubMed – rehab
