Determination of the conceptual structures of the disturbed activities of daily living due to Katakori by evaluating patients' values or perceptions using a patient-elicitation technique.

PMID 34539074WHAT IT FOUND
People with Katakori, a Japanese term for neck and shoulder stiffness, identified 24 distinct ways it disturbs daily life.
The most common issues were using computers and phones, while caring for children was rated the most burdensome. Existing questionnaires missed these specific problems.
Key findings
01Participants identified 24 specific categories of disturbed daily activities, with 'using a personal computer' and 'using a mobile phone or tablet' being the most prevalent.
02The activity with the highest overall burden score was 'taking care of children', followed by 'using a personal computer' and 'wearing a backpack'.
03Standard measures like the Neck Disability Index showed weak correlations with the patient-elicited burden, indicating they do not accurately capture the specific daily life disturbances caused by Katakori.

What it does not show
The sample was small (50 participants) and recruited via social media, introducing self-selection bias. The study focused on content validity of measures, not treatment efficacy. Participants were relatively young (mean age 26.3 years), so findings may not apply to older adults with Katakori. Existing questionnaires showed weak correlations, but this does not prove they are useless, only that they measure different constructs than the patient-elicited technique.
Declared interests
None declared.
The easy way to misread this
Do not assume that existing neck disability questionnaires are invalid for all purposes; this study shows they do not capture the specific daily activities patients find most burdensome, but they may still be useful for other clinical goals. Also, do not generalize these specific activity rankings to all patients with neck pain, as this study focused on a culturally specific Japanese term (Katakori) and a young, self-selected online sample.
