PRIMARY outcome

Timeframe: From baseline to the end of treatment at 8 weeks

Population: This only applied to participants in the interventional group who had indicated good, very good, or excellent in regards to their perceived ability to control their head and neck lymphedema.

Evaluate the feasibility and potential effectiveness of the Flexitouch head and neck garments by monitoring treatment satisfaction using a satisfaction survey. A survey assessed participants' perceived ability to control their head and neck lymphedema before (at baseline) and after the usage of the Flexitouch at 8 weeks. Values represent a count of participants who indicated good, very good, or excellent.

The change in percent of sites with visible swelling and inflammation as assessed via endoscopy (using Modified Patterson Scale) from baseline to week 8. The range for each anatomical structure includes 1-4: Normal, Mild, Moderate, and Severe. A lower score means a better outcome. A greater negative value indicates a greater reduction in swelling. Total score range: 0-100%.

Timeframe: From baseline to the end of treatment at 8 weeks

The presence of swelling and inflammation was assessed in all participants through grading of external lymphedema via the Head and Neck Lymphedema and Fibrosis Assessment criteria (HNLEF) during a physical examination at baseline and 8 weeks. A total of 9 sites were evaluated for the presence of lymphedema and graded from 1 (mild) to 3 (severe) at each site. The number of sites ranged from 0-9 with a total severity score ranging from 0-27. Results are the change in a total score between baseline and 8 weeks. A lower score indicates a better outcome. A greater negative value indicates a greater reduction in swelling.

Timeframe: From baseline to the end of treatment at 8 weeks

The function was assessed in all participants at baseline and week 8 through the jaw range of motion measurements using the Therabite Jaw ROM Scale. The TheraBite Jaw ROM Scale was used to measure in millimeters the jaw opening of the maximum inter-incisal distance (upper right central to lower right central incisor). The values were categorized by grade change. The change of -1 indicates the severity improved by one grade. A value of zero indicates a participant remained stable. A value of 1 indicates a patient worsened by one grade.

The function was assessed in all participants at baseline and week 8 by the Neck Disability Index (NDI). Values represent a change from baseline. Minimum score: 0 with a minimum disability of 0%. Maximum score: 50 with a maximal disability of 100%. 0 - 20% (minimal) - The patient can cope with most living activities. Usually, no treatment is indicated apart from advice on lifting sitting and exercise. 21 - 40% (moderate) - The patient experiences more pain and difficulty with sitting lifting and standing. Travel and social life are more difficult and they may be disabled from work. The patient can usually be managed by conservative means. 41 - 60% (severe) -Pain remains the main problem in this group but activities of daily living are affected. These patients require a detailed investigation. 61 - 80% (crippled) - Pain impinges on all aspects of the patient's life. Positive intervention is required. 81 - 100% (bed bound) - Need to exclude exaggeration or malingering.

SECONDARY outcome

Timeframe: From baseline to the end of treatment at 8 weeks

Population: Data was not available and/or applicable to all participants in certain categories.

Symptoms were assessed in all participants at baseline and week 8 via the Vanderbilt Head and Neck Symptom Survey plus General Symptom Survey (VHNSS v2.0 plus GSS). Values represent a median score change from baseline. Score range: 0-10. A lower score indicates a better outcome. A more negative value indicates a greater change from baseline. Given this was a self-reported survey, responses were not mandatory and thus missing for some subjects.

SECONDARY outcome

Timeframe: From baseline to the end of treatment at 8 weeks

Quality of life was assessed in all participants at baseline and week 8 using the Linear Analog Self-Assessment. The total score for the assessment ranged from 0-50. Each category represents a change in score from the baseline visit which ranged from positive 4 to negative 4. A positive change indicates an improvement. Values represent the count of participants in each category.

Timeframe: From baseline to the end of treatment at 8 weeks

Population: Data may be missing or left blank by participant.

Lymphedema Symptom Intensity and Distress Survey-Head and Neck (LSIDS-HN) assessed the measurement characteristics of a symptom burden for participants with head and neck lymphedema at baseline and week 8. Each symptom was rated on intensity and distress using a 5-point scale. A maximum response for any symptom within a given cluster was used for the analysis. The total score ranged from 0-10. The values represent a change from baseline. A lower score means a better outcome.
