I In response to questionnaires sent to 10, 116 male workors, effective answers were obtained from 8, 055 employees.The 8, 055 respondents were classified into either "A" group consisting of 4, 684 shop workers or "B" group consisting of 3371 clerical workers, who were further classified into four categories by severity of back pain as follows:1) Those who have no back pain at all and are capable of heavy labor.2) Those who are capable of daily work but have occasional back pain when performing heavy labor.3) Those who have difficulty performing work in the stooped position due to a bad back.4) Those who have difficulty even performing daily routines due to a bad back.Defining, in narrow terms, only (3) and (4) above as bad backs, 7.3% of the "A" group workers and 5.3% of the "B" group workers were found to fall into these categories. It was observed that with both the "A" group and "B" group, the number of workers complaining about bad backs would increase with age. Of the 520 workers falling into the narrow (3) and (4) categories, 140 were given direct physical examinations, faring poorly on the objectivecomment scale as compared with what they scored on the subjective-symptom and daily-life-activity scales.
