Physical activity was measured for 3 days (minimum of one weekend day) using 3 standardized methods simultaneously. Total body movement was assessed by the Caltrac accelerometer and the University of Cincinnati Motion Sensor (UCMS). The Caltrac measured movement in the vertical plane; the UCMS measured movement of 10\u00b0 or more from the horizontal plane. The type and intensity of daily physical activity was measured by the 3\u2010day activity record, which also recorded the number of hours of daily sleep. Participation and duration of involvement in organized sports was ascertained by questionnaire.<\/jats:p><jats:p><jats:bold>Results.<\/jats:bold> The mean physical activity was significantly lower in JRA patients than in controls for the activity diary (P = 0.05). However, daily body movement measured by the Caltrac and UCMS were similar for both groups. Differences were seen in the number of hours of sleep per day (P = 0.02) and participation in strenuous activities (P &lt; 0.01). JRA patients had significantly less participation in organized sports (P = 0.01).<\/jats:p><jats:p><jats:bold>Conclusion.<\/jats:bold> There was less daily physical activity by this group of JRA patients than for healthy age\u2010and sex\u2010matched control subjects.<\/jats:p>","DOI":"10.1002\/art.1790080210","type":"journal-article","created":{"date-parts":[[2007,2,15]],"date-time":"2007-02-15T02:01:43Z","timestamp":1171504903000},"page":"114-119","source":"Crossref","is-referenced-by-count":86,"title":["Physical activity in children with juvenile rheumatoid arthritis: Quantification and evaluation"],"prefix":"10.1002","volume":"8","author":[{"given":"Carol J.","family":"Henderson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel J.","family":"Lovell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bonny L.","family":"Specker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara N.","family":"Campaigne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,12,15]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(92)90707-6"},{"key":"e_1_2_1_3_2","first-page":"449","article-title":"Influence of training and of inactivity on muscle strength","volume":"51","author":"Muller EA","year":"1970","journal-title":"Arch Phys Med"},{"issue":"9","key":"e_1_2_1_4_2","first-page":"S171","article-title":"Bone mineral content in juvenile rheumatoid arthritis and healthy controls (abstract)","volume":"36","author":"Lovell DJ","year":"1993","journal-title":"Arthritis Rheum"},{"key":"e_1_2_1_5_2","volume-title":"Physical Therapy","author":"Scull S","year":"1989"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.1790040305"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1249\/00005768-198606000-00001"},{"key":"e_1_2_1_8_2","first-page":"195","article-title":"Current proposed revision of JRA criteria","volume":"20","author":"Brewer EJ","year":"1977","journal-title":"Arthritis Rheum"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780340713"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1249\/00005768-199010000-00023"},{"key":"e_1_2_1_11_2","first-page":"218","article-title":"The validity of a portable accelerometer for estimating energy expenditure in bicycle riding","volume":"29","author":"Hunter GR","year":"1989","journal-title":"J Sports Med Phys Fitness"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a114121"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1080\/02701367.1984.10608408"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1249\/00005768-198710000-00015"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0895-4356(89)90114-5"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1080\/02701367.1988.10605479"},{"key":"e_1_2_1_17_2","first-page":"563","article-title":"Validity of motion sensor to measure physical activity in infants and children","volume":"10","author":"Specker B","year":"1991","journal-title":"J Am Coll Nutr"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a114163"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1080\/02701367.1990.10607475"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/53.4.839"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/34.11.2540"},{"key":"e_1_2_1_22_2","volume-title":"Biostatistical Analysis","author":"Zar JH","year":"1984"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1949.02900430001001"},{"key":"e_1_2_1_24_2","first-page":"105","article-title":"Habitual physical activity and health","volume":"6","author":"Lange A","year":"1978","journal-title":"Copenhagen WHO Reg Pub Europ Series"},{"key":"e_1_2_1_25_2","doi-asserted-by":"crossref","first-page":"669","DOI":"10.1016\/S0002-8223(21)01202-5","article-title":"Accuracy of maternal dietary recall for preschool children","volume":"91","author":"Baranowski T","year":"1991","journal-title":"J Am Diet Assoc"}],"container-title":["Arthritis &amp;
