"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.

Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Introduction: Gait is the normal way of walking pattern. The visual system of sighted subjects furnishes information concerning the environment from distant and plays important role in maintaining the stability and planning of the route during locomotion. During movement of the sighted subject, the visual perception of the surroundings enables the orientation towards the goal. Movement and position of limbs is also important in order to adjust foot clearance or foot placement to regulate the walking pace.

Aim: To compare the gait pattern among blind and blind folded sighted subjects as well as among healthy and underweight blind and blind folded sighted subjects.

Materials And Methods: The cross-sectional study was conducted in Department of Physiology, RKDF Medical College Hospital and Research Centre, Bhopal, Madhya Pradesh, India, from October 2019 to April 2021. A total of 181 sighted and 150 blind subjects aged between 10-17 years were taken in the study. Foot print method was used to record spatial components. The temporal components were measured with stop watch. Rivermead Visual Gait Analysis (RVGA) was use to analyse kinematic characteristics. The estimation of healthy and underweight subjects were done by calculation of Body Mass Index (BMI). Quantitative data was expressed as mean±standard deviation. Statistical Package for the Social Sciences (SPSS) version 20.0 was used for statistical analysis.

Results: The mean value of gait in blind folded sighted and blind subjects was found to be 3.28±0.48 and 2.01± 0.79 respectively and was found statically significant having (p-value=0.001). The results of mean value of gait on the basis BMI, the healthy blind folded sighted and healthy blind subjects showed 3.29±0.46 and 1.99±0.75 respectively (p-value=0.001). Similarly, the gait pattern in underweight blind folded sighted and underweight bind subjects was observed to be 3.26±0.61 and 1.98±0.77 respectively (p-value=0.001).

Conclusion: The gait pattern was found to be significantly better among the blind folded sighted subjects in comparison to the blind subjects.


Foot, Movement, Perception, Stability, Visual

Gait is a manner of walking pattern of the individuals. It involves balance and muscles coordination so that the body is propelled forward in a flow. In general, the characteristic of gait pattern is instituted during the course of motor development for specific situations. The gait patterns are well assembled and established as motor patterns in brain mostly at the seventh years of the childhood age (1). There may be inadequate gait process in case of any damage at cognitive or organic level of an individual. Locomotion is to walk gracefully, comfortably and safely (2). The system of vision helps to receive knowledge about the environment from a distance and plays an essential role during mobility in the preservation of balance and for planning of route. Visual appreciation of the environments during locomotion allows orientation towards a goal, adjusting moving direction, avoiding strikes with objects, keeping away obstacles and accommodating different surfaces.Visual perception of self-motion, limb movement and limb motion is also essential in order to adjust either foot clearance or foot placement and to regulate the pace movement (3),(4),(5).

Most often, it has been observed that the congenital blind individuals have shorter and wider stride length. They show flexed knees even at stance, reduced speed and heel strike causing dragging. They do not exhibit swinging of reciprocal arms and increased in out toeing than the normal sighted person. They also show higher error in foot placement and generally get deviated from the straight path (6).

A few studies exist reporting on the movement of the body during locomotion among visually challenged subjects. Most of the studies pointed out the effect of low sight on mobility of older people (7). The execution of mobility is frequently distinguished by percentage of preferred walking speed acquired in a disordered environment. In the study of Hallemans A et al., it had been observed that the percentage of preferred walking speed reduced in case of subjects with low vision and in congenitally visual challenged subjects (8). Turano KA et al., observed that the glaucoma in subjects is associated with decreased walking performance. They stated that mean walking pace of the glaucoma subjects was 10% slower than the mean walking pace of the normal sighted subject (9). Nakamura T observed that, the visually impaired individuals, either congenital or late blind showed decreased speed, small stride length and increased stance duration (6).

Some observations are available on kinematics movement in case of reduced vision. It was also observed that cataract enhanced the toe clearance and substantial variability of limb elevation during hurdle avoidance task (4). Nakamura T also compared step time parameters of gait in normal sighted, late blind and congenital blind individuals.Where, the sightless persons had always shown decreased walking pace, reduced stride length and increased time of instance. Therefore, these findings support a better stability of the posture in case of vision loss (6).

Abualait TS and Ahsan M, mentioned that walking patterns of the individuals also fluctuate by age, Body Mass Index (BMI), surface, course of time, and it changes from stride to stride (10). Since, Since, walking is an important factor of gait, it depends on inter-relationship between central nervous system and musculoskeletal system. The balance of an individual can also be disturbed by weight alterations with respect to physical status of individual. An increased or decreased body mass have been observed for variations in gait pattern of individuals in the same age group (11). There is dearth of study on effect of BMI on gait pattern among blind folded sighted subjects and blind subjects. Thus aim of the present study was to investigate and compare the gait pattern on the basis of BMI among the blind folded sighted and blind subjects aged between 10-17 years.

Material and Methods

The cross-sectional study was conducted in Department of Physiology, RKDF Medical College Hospital and Research Centre, Bhopal, Madhya Pradesh, India, from October 2019 to April 2021. The study included 181 sighted and 150 blind subjects of either sex and age group between 10-17 years. The written informed consent was received from all the participants (331) and ethical clearance (Ref outward No.540A) was obtained from Institutional Ethical Committee prior to conduct the study.

Inclusion criteria: Sighted and blind subjects aged between 10-17 years of both sexes were included in this study.

Exclusion criteria: Subjects with any type of neurological illness that affect our sensory and motor function, brain damage, traumatic brain injury, autoimmune disorder, substance abuse, attention deficit disorder, learning disability were excluded from this study.

The estimation of healthy and underweight children was done by calculation of Body Mass Index (BMI) i.e., BMI= weight/height (kg/m2). The BMI in childhood changes substantially with age (12). The cut-off values of BMI of underweight subjects aged 10 years,11years,12 years ,13years, 14years, 15years, 16 years and 17 years are<13.4, <14, <14.4, <14.8, <15.4, <15.9, <16.4 and <16.8 respectively. Whereas, the BMI (kg/m2) of normal healthy subjects aged 10 years, 11 years, 12 years, 13 years, 14 years, 15 years, 16 years and 17 years are 13.7-18.5, 14.1-19-2, 14.1-19.2, 14.5-19.9, 14.9-20.8, 15.5-21.8, 16.0-22.7, 16.5-23.5 and 16.9-24.3 respectively (13).


The scale used for this study was Rivermead Visual Gait Analysis scoring (RVGA) (14). The 10 meter walkway distance was marked on corridors having smooth surface, hard without any hurdle and pleasant surroundings were provided to both groups. The participants were described about this study and instructed to walk with congenial walking pace. Further no commands were given for style of walking and posture correction aspects. Footprint method was used to note spatial components. The temporal parts were measured with a stopwatch and manual measurement of steps. White cardboard paper with dimension 2 feet wide and 6 feet long was attached in the walkway with adhesive tape and the subjects were instructed to walk on the given walkway after their feet were inked as shown in (Table/Fig 1), (Table/Fig 2). The subjects were advised to walk as straight as possible freely till they were told to stop. The assessments of stride length, step length, frequency of steps, time taken for participants to finish 10 m distance were written down. Walking speed was calculated as distance walked in second i.e., 10 meters / total time taken in seconds. The cadence was calculated with the use of steps frequency for the duration of 10 m walkway by formula cadence (15) i.e.,

Number of steps per minute = No. of steps taken during 10 m walk X 60 sec / time taken to complete 10 m walkway in sec.

The variables which were used to determine the gait in present study is in accordance with the study done by Aruna R et al., (16).

Statistical Analysis

Quantitative data was expressed as mean±standard deviation. Statistical Package for the Social Sciences (SPSS) version 20.0 was used for statistical analysis with the help of unpaired t-test, p-value <0.05 was considered as statistically significant.


In this study, the mean age of sighted and blind subjects was observed to be 13.87±2.10 years and 13.92±2.06 years respectively (p-value=0.8193). Demographic details are presented in (Table/Fig 3).

The mean value of the step length of gait in blind folded sighted and blind was observed to be 0.62±0.04 m and 0.48±0.09 m respectively (p-value=0.001). The mean value of RVGA score of blind folded sighted and blind was 6.5±2.9 and 14.5±4.82 respectively. All these parameters were statistically significant (p-value=0.001) (Table/Fig 4).

The results of mean value of gait on the basis Body Mass Index (BMI), the healthy blind folded sighted and healthy blind subjects showed 3.29±0.46 kg/m2 and 1.99±0.75 kg/m2 respectively (p-value=0.001). Similarly, the gait pattern in underweight blind folded sighted and underweight bind subjects was observed to be 3.26±0.61 and 1.98±0.77 respectively (p-value=0.001) (Table/Fig 5).


The present study observations showed that the lack of vision among the blind subjects affected the gait dynamic stability. Hallemans A et al., also observed that the visual deprivation in blind subjects affected spatio-temporal gait parameters (17). In this study, it was observed that step length and stride length varied significantly in blind subjects in comparison with blind folded sighted subjects. The decreased stride length in blind subjects, point out the tendency to withstand longer amplitude excursion of centre of gravity from the mid plane of the body. Thus, the reduced stride length and step length helps the blind subjects in maintaining the balance for safety concern (16). It was also observed that stride frequency and walking velocity was decreased in blind subjects in comparison to blind folded sighted subjects. These findings are due to the properties of gait not allowing the centre of gravity to fall outside the base support in the case of blind subjects. The low pace in terms of steps carried out per minute and the distance travelled in given time represents that the each step is taken carefully with great protection. The conclusion of this comparative study is supported by the study from Nakamura T (6).

In 1986, Rosen S and Dodson B, mentioned that persons with congenital vision impairment had shown shorter stride length, step length and slow walking velocity. Many researchers have also mentioned that the stride length and step length of the blind subjects were differed significantly from the normal sighted individuals (18). The The present study had also shown that the blind subjects had shorter stride length mean 0.96±0.18, step length mean 0.48±0.09, stride rate mean 33.69±6.64, standing time 1.83±0.32 and reduced walking velocity mean 2.01±0.79 than the blind folded children having stride length mean 1.24±0.08, step length mean 0.62±0.04, stride rate mean 44.06±5.29, standing time 1.38±0.16 and walking velocity mean 3.28±0.48. The findings in this study were very much similar to the study done by Aruna R et al., They too had shown the stride length (mean=91.90), step length (mean=45.59), walking velocity (mean=0.6340) and RVGA score (mean=14.00) among blind children. Whereas the stride length (mean=114.7), step length (mean=59.4), walking velocity (mean=0.8245) and RVGA score (mean=6.05) were observed among blind folded normal children (16). In accordance with this study, Iosa M et al., have also observed a decreased in preferred walking velocity in blind subjects in comparison to blind folded sighted subjects (19). This is due to a conventional strategy among blind that the longer time duration in haptic foot exploration reduces the fear of falling.

Shimizu J et al., observed one of the largest statistically insignificant discrepancies in stride rate between the blind and sighted individual, while in this study the mean stride rate in blind and blind folded sighted subjects was found to be statistically significant (p-value=0.001). Even though the blind subjects was ensured that there was no any object present in their path, they were still very cautious in safety concern (20).

The fact that the significant difference was observed in mean standing time among blind and blind folded sighted subjects indicates that blind subjects show a longer stance parameter of their gait cycle. This contradicts the findings of Hallemans A et al., (8) who observed blind individuals showed a similar stance phase duration.

Lack of visual information in blind subjects affects the gait pattern. Normally, a more careful walking strategy is observed in blind subjects. Our data on decreased gait patterns in blind subjects was due to lack of vision. A similar observation was found by Turano KA et al., who reported the decreases in preferred walking speed among blind individuals due to careful walking strategy followed by blind individuals to prevent from fear of falling (21).

In this study, authors observed the significantly huge difference in gait patterns in healthy blind folded sighted and underweight blind. Healthy blind folded sighted subjects performed very well in assessment of gait parameters than underweight blind. Since, normal body mass is essential to maintain the postural balance and better gait pattern (11).

The observations in this study, elicits that vision as well as body mass of the subjects cumulatively influence the gait pattern in blind subjects. These factors are considered to be important for normal walking patterns irrespective to the hunting of the specific characteristics. Further, these factors should be implemented for adaptation of position of many joints for gait characteristics.


The chief limitations of this study was that there was a need of investigations of more controlled parameters to find out the role of vision as well as body mass index of the participants for better gait analysis. Furthermore, authors have not taken the parameters that are responsible for lateral body swing during blind walk.


The present study concluded that the gait pattern was found to be significantly better among the normal sighted subjects than the blind subjects. The typical walking pattern adapted by blind subject to maintain the body stability and prevention from the fear of falling by reducing the step length, stride length, stride rate and walking velocity.
