Description of intervention(s) / exposure
Observational study comparing respiratory function and voice projection between quadriplegics and able-bodied, matched controls when singing and speaking. Physiological assessments of respiratory function and acoustic and perceptual assessments of voice projection (approx 1 hour each in duration) will constitute outcome measures for the study.
Intervention code [1] 1800 0
None
Comparator / control treatment
There is no treatment as such, just an assessment which is the same for both the quadriplegic subjects and the able-bodied matched controls
Control group
Active

Outcomes
Primary outcome [1] 2760 0
Respiratory capacity - Ventilatory function and upper airway function will be assessed using maximal flow-volume loops to determine maximal inspiratory and expiratory flow rates, and timed lung volumes. Static lung volumes will be measured using whole-body plethysmography in those subjects able to sit in the plethysmograph, or by inert-gas dilution otherwise.
Timepoint [1] 2760 0
Measured when the participant enters the study and undergoes all the physiological and voice assessments. This single measurement (comprising both the physiological and voice assessments) is the basis for comparison between subjects.
Primary outcome [2] 2761 0
Respiratory muscle strength (specifically maximal sniff and inspiratory (MIP) muscle pressures) - Respiratory muscle strength will be assessed by measuring maximal inspiratory (MIP), expiratory (MEP) and sniff (SNIP) pressures. Patterns of tidal respiration will be assessed using calibrated respiratory-inductive plethysmography (Respitrace) to document relative contributions to ventilation of thoracic and abdominal compartments. Surface measurements of muscle (EMG) activity will be made to examine the relative timing and magnitude of the contribution from respiratory and postural muscles.
Timepoint [2] 2761 0
Measured when the participant enters the study and undergoes all the physiological and voice assessments. This single measurement (comprising both the physiological and voice assessments) is the basis for comparison between subjects.
Primary outcome [3] 2762 0
Quantitative measures of voice (pitch, amplitude) - Spectrum analysis of vocal data will be conducted by extracting acoustic parameters (e.g., pitch, amplitude, and spectral characteristics) produced during speech/voice production using calibrated recording equipment and speech analysis software. These analyses will provide quantitative measures of voice quality.
Timepoint [3] 2762 0
Measured when the participant enters the study and undergoes all the physiological and voice assessments. This single measurement (comprising both the physiological and voice assessments) is the basis for comparison between subjects.
Secondary outcome [1] 4653 0
Measures of thoraco-abdominal motion, indices of respiratory flow and volume and qualitative assessments of voice. Patterns of tidal respiration will be assessed using calibrated respiratory-inductive plethysmography (Respitrace) to document relative contributions to ventilation of thoracic and abdominal compartments. Surface measurements of muscle (EMG) activity will be made to examine the relative timing and magnitude of the contribution from respiratory and postural muscles. A standardized perceptual voice assessment (Frenchay Dysarthria Assessment) will be conducted by an experienced speech pathologist. The assessment period for when these outcomes will be measured is when the participant enters the study and undergoes all the physiological and voice assessments. This single measurement (comprising both the physiological and voice assessments) is the basis for comparison between subjects.
