RESUMO

BACKGROUND: To compare the ACSM-CDC physical activity accumulation recommendation to the traditional recommendation, for impact on mood and physiological markers of fitness. METHODS: Randomized controlled trial with sedentary male (n = 21) and female (n = 19) subjects assigned to walk either long bouts (LB; 30 min/day), short bouts (SB; 3 x 10 min/day), or a nonexercise control (CTL) group for 8 weeks. Pre- and post-measures were collected for V02max and percent body fat. Pre-, mid-, and post-measures were collected for the Profile of Mood States (POMS). RESULTS: VO2max increased in the SB group (+7.2%) and LB (+6.7%; P < or = 0.05). Percent body fat decreased in the LB group (-6.7%; P < or = 0.05). Total mood disturbance (TMD) decreased in the LB and SB groups (P < or = 0.05); only the LB group showed reductions compared to the CTL group (P < or = 0.05). Tension-anxiety and vigor-activity were altered in the LB group compared to the other two groups (P < or = 0.05). Reductions in percent body fat correlated with TMD (r = 0.38; P < or = 0.05) and Tension-anxiety reduction (r = 0.40; P < or = 0.05). CONCLUSIONS: LB and SB walking produced similar and significant improvements in VO2max LB walking was more effective at reducing percent body fat, tension-anxiety and total mood disturbance, and increasing vigor compared to the control group.

RESUMO

Carpal tunnel syndrome (CTS) is the source of substantial workers' compensation claims in industrialized countries. Its pathogenesis, however, continues to be questioned. The purpose of the present study was to assess the attitudes of Canadian plastic surgeons toward Workers' Compensation Board (WCB)-supported claims for CTS and to assess patterns of resource allocation across Canada. Sixty-seven plastic surgeons were asked to read a clinical scenario and respond whether they would support a WCB claim for CTS. Provincial WCB offices were contacted and asked to provide statistics surrounding CTS claims for 1997 to 2001. Fifty-eight per cent (39 of 67) of surgeons surveyed felt that CTS should be covered as a WCB claim, while 42% (28 of 67) felt that it should not be covered by WCB. In British Columbia, 50% (six of 12) of surgeons were in support of the claim compared to 92% (11 of 12) of those from Alberta, 55% (17 of 31) of those from the Central Provinces and 42% (five of 12) of those from the Maritime Provinces. Trends of resource allocation and number of CTS claims per year are presented for the individual provinces for 1997 to 2001. An extensive literature review revealed that there is minimal to no evidence to support the view that CTS should be a compensated claim. As defined by the WCB of Canada, a compensated claim is one that "arises out of, and in the course of, employment and that results from causes and conditions peculiar to the trade, occupation or industry." The ambiguity in the beliefs of Canadian plastic surgeons in supporting CTS as a WCB claim reflects a situation where many of the decisions to cover CTS as a WCB claim are not evidence based.


Le syndrome du canal carpien (SCC) est la source d'importantes réclamations d'indemnisations de la part des travailleurs des pays industrialisés. Sa pathogenèse continue toutefois d'être remise en question. La présente étude vise à évaluer les attitudes des plasticiens canadiens par rapport aux réclamations reliées au SCC auprès de la Commission de la santé et de la sécurité du travail (CSST) ainsi que les schèmes d'attribution des ressources au Canada.Soixante-sept plasticiens ont été invités à lire un scénario clinique et à répondre s'ils soutiendraient une réclamation reliée au SCC auprès de la CSST. On a communiqué avec les bureaux de la CSST des provinces pour qu'ils fournissent des statistiques au sujet des réclamations reliées au SCC entre 1997 et 2001. Cinquante-huit pour cent (39 des 67) chirurgiens sondés pensaient que le SCC devrait être couvert par la CSST, tandis que 42 % (28 des 67) d'entre eux pensaient qu'il ne devrait pas l'être. En Colombie-Britannique, 50 % (six des 12) des plasticiens soutenaient la réclamation, par rapport à 92 % (11 des 12) des plasticiens de l'Alberta, à 55 % (17 des 31) de ceux des provinces centrales et à 42 % (cinq des 12) de ceux des Maritimes. Les tendances d'attribution des ressources et le nombre de réclamations reliées au SCC par année sont présentés pour chacune des provinces entre 1997 et 2001.Une analyse bibliographique fouillée révèle qu'il existe peu de données probantes, sinon aucune, pour soutenir une réclamation reliée au SCC. Telle qu'elle est définie par la CSST du Canada, une indemnisation découle de l'emploi et résulte de causes et de troubles propres au métier, à l'emploi ou à l'industrie. L'ambiguïté des convictions des plasticiens canadiens quant au soutien d'une réclamation reliée au SCC auprès de la CSST reflète le fait que bon nombre des décisions pour que la CSST indemnise les cas de SCC ne sont pas fondées sur des faits probants.
