Objective
To determine inter- and intra-rater reliability of the Six-minute walk test (6MWT) in individuals with Transtibial Amputation.
Design
Prospective; test-retest method by a pair of physical therapists.
Setting
Indoor Physical Therapy department of the National Institute for the Orthopaedically Handicapped (NIOH), Kolkata.
Participants
Twenty one subjects (16 men, 5 women; mean age + mean standard error: 42.95 + 3.02 year) with transtibial amputation, who had completed two weeks of prosthetic training in the Inpatient Rehabilitation set up.
Interventions
Each subject performed a total of four 6MWTs, one test for each rater, on two consecutive days at approximately the same time of day. Subjects were given at least a 20 minutes rest between tests. The order of raters were randomized on the first day and reversed for the next day. The walk tests were performed in the same enclosed corridors with the same starting point for all tests. Subjects were allowed to walk with a mobility aid of their choice. Raters used a digital stopwatch to time the tests and the distance walked was measured in meters with the help of measuring tape. The raters were blinded to each other's scores.
Main Outcome Measure
Distance walked in 6 minutes (in meters).
Results
Within-rater reliability was good, with ICCs ranging from 0.79 to 0.83. Between-rater reliability was also high, with ICCs ranging from 0.81 to 0.88. A 2-way repeated-measures ANOVA showed significant differences (P<0.001) both within raters and between raters. It was seen that the proportion of variation within raters was more for the second rater whereas the proportion of variation between raters were more on the first day i.e day 1 of the test. Regardless of the tester, distances walked on day 2 were greater than on day1.
Conclusion
Although the 6 MWT showed good evidence of inter and intra rater reliability in individuals with unilateral below knee amputation, the distances walked in 6 minutes continued to improve over time. This improvement was mainly the result of training and learning effect.

Aim of the Study
To Correlate the Predictability of Waist Circumference and Body Mass Index on Respiratory Function in Obese Children.
Purpose of the Study
Childhood Obesity has been Linked with Increased Risk of Obesity in Adulthood. during Childhood Growth, Body Fat is Deposited both Subcutaneously and Intra- Abdominally. but Body Mass Index (bmi) Gives neither any Indication about the Distribution of Fat Mass in the Body, nor the Difference in Proportion of Fat and Lean Mass. So, a Person Classified as Obese According to Bmi may have a Higher Ventilatory Muscle Mass which could Influence the Spirometric Values by Exerting a Stronger Expiratory and Inspiratory Effort. Waist Circumference (wc) Gives an Indication of Intra- Abdominal Fat Mass Distribution. Intra -abdominal Fat will Affect the Normal Biomechanics of Breathing Leading to Reduced Lung Volumes.
Objectives
To Correlate Bmi and Wc to Respiratory Function in Obese Children and to Compare the Correlation of Body Mass Index and Waist Circumference to Respiratory Function in these Obese Children.
Design
Correlation Study.
Setting: Oxford
ICSE and CBSE Schools in Bangalore.
Procedure
60 Obese Subjects (bmih"30 in Adults) in the Age Group of 7-15 Years were Randomly Selected. Wc was Measured Using Non-elastic Measuring Tape. Fvc, Fev1, Pef was Measured Using Portable Spirometer. by Doing 3 Measurements, best Value was Taken. Data Analysis Correlation and Regression Analysis were Done.
Results
Comparing the Correlations, Wc has Shown more Correlation to all the Respiratory Function Parameters than Bmi with P<0.001 Comparing the Regression Coefficients, Wc has Shown Negative Correlations to all the Respiratory Function Parameters with P<0.001 Proportion of Variation in Respiratory Function Parameters were more for Variation in Wc than for Variation in Bmi. This Study Shows that there is a Significant Negative Correlation of Wc and Bmi on Respiratory Function. and the Wc has Shown more Correlation than Bmi to Respiratory Function. the Results were Found to be Significant at P<0.001
Conclusion
It is Concluded from This Study that Wc is more Predictable than Bmi in Assessing Respiratory Functions of Obese Children. from This Study we can also Conclude that Wc can be Used as the most Simple Anthropometric Tool than Bmi in Screening the Obese Children and then Categorize those Children who are at a Greater Risk of Developing Pulmonary Dysfunction in their Adulthood through Spirometric Test.
