“…10 The disability of pain as a result of muscular fatigue had reduced the working abilities of workers muscle fatigue affected the kinetics of movements of the concerned limb. 7,11 Long driving time was associated with increased body weight the risk factors found to be lack of time for exercise. Studies have proved that long hours of driving were associated with increase in waist circumference.…”

“…6 Our study proved that driving was associated with muscle fatigue and decrease in muscle power as the power of the muscle measured immediately after driving was less compared with power of the muscle measured four hours after driving this had been proved in a study where continuous motor activity resulted in fatigue and decreased the endurance of muscle, lack of proper rest and increased liability to fatigue was found to be the risk factors. 7 Muscle fatigue affect coordination. 8 In a study which tested successful trial of movement involving the upper limb it had been proved that, without fatigue of muscles the velocity of hand movements was better in comparison with the velocity of fatigued muscles.…”

Background: Urbanization has brought a lot of health issues in the citizens. Commuting for work has become more common. People around the world use different means of commute like public transport or driving a car to work. The increase in time of commute may be associated with many health hazards. In this study we try to study the impact of driving duration on hand muscle power.Methods: A prospective cross sectional study was conducted in a tertiary care hospital. About 32 persons who drive car for their work participated in this study after giving their consent. Subjects grouped in to two categories long commuters, who drive for greater or equal to one hour and short commuters less than one hour. Muscle power tested on two occasions immediately after driving and four hour after driving with a help of hand grip dynamometer. Demographic details were collected. The two groups compared for muscle power and body mass index (BMI).Results: The long commuters had less muscle power in comparison with short commuters and it was significant. The average BMI of long commuters was in obesity range were as the average BMI of short commuter is less and it was statistically significant.Conclusions: Driving for greater than one hour is associated with obesity and reduced muscle power immediately after driving.

Background: Low back pain has been configured as a public health problem capable of compromising functional capacity, even in adolescents, however, there are no validated instruments for Brazilian adolescents. Objective: Validate the psychometric properties of the Nordic questionnaire for the evaluation of low back pain in Brazilian adolescents. Methods: The sample consisted of 150 adolescents (84 female), aged between 15 and 19 years. The Nordic questionnaire for the evaluation of low back pain in adolescents, was translated and culturally adapted into Portuguese (Brazil). A committee of experts followed the entire validation process. The questionnaire was administered in two moments, with a 14-day interval. Statistical analysis involved Kappa index. Results: After the slight modifications in the translation process, the expert committee considered that the Brazilian Portuguese version of the questionnaire presented semantic, idiomatic, cultural and conceptual equivalence. The results showed that, among the 15 items considered in the eight questions of the questionnaire, 66.6% presented substantial agreement (kappa between 0.61-0.80). The other items presented almost perfect agreement (kappa > 0.80). Conclusion: The Nordic questionnaire for the evaluation of low back pain in adolescents, after being translated and culturally adapted into the Portuguese (Brazil) language, showed adequate psychometric properties, with high reproducibility in all items, demonstrating that it can be used safely to evaluate the low back pain in Brazilian adolescents.

“…Back endurance testing is a statistically accurate LBP screening test as poor performance in static back endurance correlates to higher incidence. 68 69 However, EIL is a passive test using the arms as the prime mover. It is possible that individuals with excessive lumbar extensor activation and substitution during this test may confound the results.…”

ObjectivesInvestigate the relationships between the ability/inability to perform five physical test exercises and the presence or absence of low back pain (LBP).SettingRegional Australian council training facility.ParticipantsConsecutive participants recruited during 39 back education classes (8–26 participants per class) for workers in general office/administration, parks/gardens maintenance, roads maintenance, library, child care and management. Total sample (n=539) was reduced through non-consent and insufficient demographic data to n=422. Age 38.6±15.3 years, range 18–64 years, 67.1% male.MethodsCross-sectional, exploratory, observational investigation. LBP presence was ascertained from a three-response option questionnaire: 0=none/rarely (no) 1=sometimes (some), 2=mostly/always (most). Statistical correlation was performed with the number of the five test exercises the individual successfully performed: (1) extension in lying: 3 s; (2) ‘toilet squat’; feet flat, feet touched: 3 s; (3) full squat then stand up: 5 times; (4) supine sit-up, knees flexed: 10 times; and (5) leg extension, supine bilateral: 10 times.InterventionsNil.ResultsFor the group ‘no-some’, 94.3% completed 4–5 test exercises, while for group ‘With’, 95.7% completed 0–1 test exercises. The relationship between LBP presence and number of exercises performed was highly significant (χ2 (10)=300.61, p<0.001). Furthermore, multinomial logistic regression predicting LBP (0=no, 1=some, 2=most) from the number of exercises completed, substantially improved the model fit (initial-2LL=348.246, final-2LL=73.620, χ2 (2)=274.626, p<0.001). As the number of exercises performed increased, the odds of reporting ‘some LBP’ or ‘most LBP’ dropped substantially (ORs of 0.34 and 0.17, respectively).ConclusionThe ability to complete/not complete five test exercises correlated statistically and significantly with a higher LBP absence/presence in a general working population. Training individuals to complete such exercises could facilitate reductions in LBP incidence; however, causality cannot be inferred. Randomised trials are recommended to establish the potential efficacy of exercise-based approaches, considering these five selected exercises, for predicting and managing LBP.
