The aim of the presented study is to examine the effectiveness of sensory stimulation in reducing pain and stress of patients diagnosed with Disorder of consciousness.
Background: Disorder of consciousness (DOC) is a medical state in which the person's ability to be aware of himself and his surroundings is impaired due to an acquired brain injury. Neuroimaging during nociceptive stimulation in patients with DOC shows an activation in the network affiliated with the affective dimension of pain, providing evidence that patients can feel pain without behavioral signs. While patients not experiencing DOC receive medical care for reducing pain derived from daily medical procedures, patients with DOC receiving these same medical procedures do not receive such care for pain alleviation. Sensory stimulation has been found as an effective intervention for the stabilization and improvement of physiological signs, yet its' effectiveness in reducing pain in patients with DOC has not been studied.
Methods: Crossover experimental research will be conducted on one focus group without a control group, that includes recurring tests prior and after intervention. At the first stage of the research, the data will be collected twice a day, for fourteen days, once when the patient is in rest and once pre- and post-endotracheal suction. The second stage will include interventions based on two arms - auditory stimulation and a combination of auditory and tactile stimulations at the same time. Measures will be collected in days one, seven and fourteen in each arm. All measures will be applied pre- and post-endotracheal suction which will be conducted after the intervention period, as specified above, and during a patient rest period before and after intervention. Both interventions will be conducted for ten minutes each, twice daily, for fourteen days.
Population: After receiving consent to participate in the study from a guardian,15 adults aged 30-75, diagnosed with DOC, hospitalized in prolonged respiratory department will participate.
Tools: Physiological signs, behavioral pain scale, Modify Ashworth Scale, Brain Engagement Index.
Expected Results:
Statistical significance will be found between measurements prior to interventions (control) and after interventions, both during rest (clinical pain) and during medical procedures, in the following measures:
Statistical significance will be found in the levels of attention during interventions (sensory stimulations) in comparison to before the interventions (control), where the former will be higher in comparison to the latter.
Statistical significance will be found in the efficiency of multi-sensory stimulations in comparison to a single sensory stimulation, where the former will show lower physiological signs, spasticity, and levels of pain during rest and medical procedures.
Findings may improve the quality of life in patients with respiratory distress, diagnosed with DOC, providing additional treatment options for pain management other than medications.

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Auditory stimulation | Behavioral | The patient will be exposed to music that he used to enjoy (from the family's or guardian's report) through headphones. In case no report is given, nature (brook) sounds will be streamed. |
| Measure | Description | Time Frame |
|---|---|---|
| Behavioral pain scale (BPS) change | BPS evaluates three behavioral domains (facial expressions, movement of upper limbs, and compliance with ventilation) that are based on observation of the patient body's posture and his response to a nociceptive stimulation. Each subscale is scored from 1 (no response) to 4 (full response). Therefore, possible BPS scores range from 3 (no pain) to 12 (maximum pain). | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arms 1 & 2 twice on days 1, 7, 14 |
| Modify Ashworth scale (MAS) change | MAS is used to measure the increase of muscle tone which is manifested by an increased resistance of joints to passive movement. The MAS measures on the following 6 level ordinal scale: 0 = no increased resistance; 1 = slightly increased resistance (catch followed by relaxation or minimal resistance at the end of the range of motion); 1+ = slightly increased resistance (catch followed by minimal resistance throughout less than half of the range of motion); 2 = clear resistance throughout most of the range of motion; 3 = strong resistance; passive movement is difficult; 4 = rigid flexion or extension. | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arms 1 & 2 twice on days 1, 7, 14 |
| EEG brainwave change | EEG will be sampled using the Mind-Wave dry electrode system, with one frontal electrode and one reference electrode on the earlobe, at a sampling rate of 512Hz. Positioning of the electrode conforms with the goal of monitoring prefrontal activity, which may correlate with attention regardless of the site of lesion. The sampled data is transferred through a wireless connection to the computer, where the Brain Engagement Index (BEI) is processed in real-time every 10 seconds and presented by the BEI monitor. | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arms 1 & 2 twice on days 1, 7, 14 |
| Respiratory Rate (RR) change |

| Screening tool Coma Near Coma (CNC) scale | The CNC is a scale for patients with acquired brain injury, who function at very low levels of consciousness. The scale evaluates the occurrence of responses to visual, auditory, command following, threat response, olfactory, tactile, pain and vocalization. The CNC is both a quantitative assessment-with scores ranging from 4 (lowest level of consciousness) to 0 (highest level of consciousness)-and a qualitative assessment-with 5 levels comprising extreme coma (3.5-4), marked coma (2.9-3.49), moderate coma (2.01-2.89), near coma (0.9-2), no coma (0-0.89). Patients will be considered for the research between level 4-extreme coma to level 1-near coma. |

The set ventilatory rate is the minimum number of breaths delivered to the patient per minute. The actual rate may be higher than the set rate if the patient is initiating spontaneous breaths. Rate is also a determinant of ventilation and is adjusted in response to the patient's CO2 (carbon dioxide) levels. RR will be collected from the patient's respiratory machine.
| Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arm 1 twice daily for 14 days; Change from baseline measured during arm 2 twice daily for 14 days |
| Tidal Volume (TV) change | Tidal volume (TV) is the volume of gas delivered to the patient with each breath. Tidal volume may also be expressed as TV. TV is only set for volume-controlled modes of ventilation and is usually 8-12cc/kg of body weight. TV will be collected from the patient's respiratory machine. | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arm 1 twice daily for 14 days; Change from baseline measured during arm 2 twice daily for 14 days |
| Peak Inspiratory Pressure (PIP) change | Inspiratory pressure reflects global alveolar pressure and is monitored continuously. The maximum allowable PIP is set on the ventilator. If the PIP exceeds the set value, an alarm will sound, and gas delivery will halt until the next breath is triggered. The normal peak inspiratory pressure on a mechanically ventilated patient with normal lungs is approximately 20cm H2O (water). The maximum allowable peak pressure varies from patient to patient. The pulmonologists determine the safest pressure for each patient. PIP values should be trended in volume-controlled modes to detect changes in pulmonary compliance. PIP will be collected from the patient's respiratory machine. | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arm 1 twice daily for 14 days; Change from baseline measured during arm 2 twice daily for 14 days |
| Systolic Blood Pressure (SBP) change | SBP will be measured using monitoring equipment located in the departments. A device from Philips Medical Systems will be used. USA Model Suresigns VS2 +. Cross-sectional values for systolic blood pressure: norm 120-129, normal-high 130-139, and hypertension ≥140. SBP will be collected using a monitoring equipment located in the departments. | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arm 1 twice daily for 14 days; Change from baseline measured during arm 2 twice daily for 14 days |
| Diastolic Blood Pressure (DBP) change | DBP will be measured using monitoring equipment located in the departments. A device from Philips Medical Systems will be used. USA Model Suresigns VS2 +. Optimal diastolic blood pressure values <80, with cross-sectional points to norm 80-84, normal-high 85-89, and hypertension ≥90. DBP will be collected using a monitoring equipment located in the departments. | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arm 1 twice daily for 14 days; Change from baseline measured during arm 2 twice daily for 14 days |
| Heart Rate (HR) change | HR will be measured using monitoring equipment located in the departments. A device from Philips Medical Systems will be used. USA Model Suresigns VS2 +. The average pulse value is 60-80 beats per minute. HR will be collected using a monitoring equipment located in the departments. | Baseline is measured pre-intervention twice daily for 14 days. Change from baseline measured during arm 1 twice daily for 14 days; Change from baseline measured during arm 2 twice daily for 14 days |
| This tool will be used once as a filter to participate in research one day prior to measuring the baseline |
