"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: In Cerebral Palsy (CP), sensory perception is affected in addition to the motor symptoms. Now-a-days, treatment solely focuses on diagnosed motor deficiencies, often overlooking underlying sensory abnormalities and their examination. Therefore, including a clinical sensory examination in the evaluation of children with CP is crucial.

Aim: To develop a validated measure for assessing sensory processing among children with CP.

Materials and Methods: This study, conducted as part of a Ph.D. research project, employed an exploratory sequential research design. It commenced on March 1, 2020, and concluded on October 18, 2021, at the Physiotherapy Out Patient Department (OPD) of Swami Vivekanand Subharti University in Meerut, Uttar Pradesh, India. Validity tests, including Scale Level Content Validity Index (CVI) and Spearman rank correlation methods, were used alongside other subtests. The study consisted of two phases: Development and Validation. An extensive literature search and parent interviews were conducted to comprehensively understand and collect information on sensory issues. Based on this information, a preliminary questionnaire draft was created. Three categories of validity-content, face, and concurrent-were tested. Content validation involved employing a three-round online Delphi approach. Face validity was assessed through opinions from clinicians regarding the questionnaire’s appearance. Concurrent validity was established by comparing the Sensory Outcome Measure (SOM) with the criterion measure scale, Short Sensory Profile (SSP).

Results: For all items, Content Validity Ratio (CVR) and item-level CVI values ranged from 0.8 to 1. The overall Scale Level CVI (average) for the scale was 0.890625. Experts exhibited a 96% agreement regarding the appearance of the questionnaire, indicating complete agreement. The Spearman rank correlation coefficient value was 0.866, and the correlation graph indicated a positive association between the two scales in terms of concurrent validity.

Conclusion: The Sensory Outcome Measure (SOM) has been developed as a valid scale with high content and face validity, along with excellent concurrent validity. SOM is the first measuring scale developed in India and used for assessing sensory deficits in children with CP.


Content validity index, Content validity ratio, Sensory outcome measure, Short sensory profile

Although CP is primarily characterised by physical impairments, a significant number of people with CP also experience cognitive and sensory deficits, which can affect the prognosis of the condition. Since motor recovery relies on sensory involvement, it is crucial to develop a scale that encompasses all associated sensory domains. Currently, existing scales have been designed and validated primarily with a focus on motor difficulties (1). Sensory processes such as stereognosis, two-point discrimination, proprioception, and visual perception have frequently been found to be linked to motor functions (2). Deficits in lower extremity senses and tactile perception have a significant impact on gait (3). Moreover, sensory processing in CP children is correlated with their abilities for daily living and social interactions with their environment (4). There are limited tools available for evaluating sensory processing. One comprehensive and validated checklist for assessing integrated sensory processing is the sensory profile, which is a parent-reporting instrument that captures children’s reactions to sensory events in their daily lives. However, no studies have been found that specifically utilise this instrument to assess and characterise sensory processing in children with CP (5). The aim of this study was to develop an outcome measure that can document all sensory modalities in children with CP by correlating it with other available tools for sensory testing. This study created an assessment scale that can be used to examine sensory problems in children with CP. The results demonstrate that this newly developed tool is effective in assessing sensory issues in children with CP.

Material and Methods

The study follows an exploratory sequential research design, consisting of two phases and subphases, aimed at creating and validating SOM for children with CP. The research was carried out at the physiotherapy OPD of Swami Vivekanand Subharti University in Meerut, Uttar Pradesh, India. It spanned two years, beginning with a literature search on 10/10/2019 to gather items related to the target domains. Subsequently, the questionnaire draft was formulated, and validity testing commenced upon receiving approval from the university’s ethical committee (ref no SMC/UECM/2021/24/153) on 21/4/2021. The validity testing concluded on 12/10/2021, with the last sample received.

Development Phase

Domain identification and item generation (6): The items for the newly developed SOM were generated using two techniques: an extensive literature search and in-depth direct interviews. Items that exhibited a certain relationship were identified, grouped, and used to create domains (7).

Literature search: Between January 1990 and February 2020, relevant English literature was searched in databases such as PubMed, Cochrane Library, and Google Scholar to identify sensory domains and assessment tools. Following a comprehensive literature search, a total of 14 tools were selected for item generation: Infant/Toddler Sensory Profile Caregiver Questionnaire, Paediatric Clinical Test of Sensory Interaction for Balance, Nottingham Sensory Assessment, The Classroom Sensory Environment Assessment, Sensory Eating Problem Scale, The Sensory Processing Scale (Expanded), Sensory Experiences Questionnaire Version 3.0, DeGangi-Berk Test of Sensory Integration, Short Sensory Profile (SSP), Sensorimotor Clinical Observation, Sensory Processing Measure, Comprehensive Observation of Proprioception, Test of Ideational Praxis, and the Miller Assessment for Preschoolers.

Interview: The investigator conducted direct interviews with 20 parents of children with CP in the OPD. Unstructured interview questions were designed, and interviews lasted approximately one hour on various days. The questions addressed the problems that these children experience in their day-to-day lives related to vision, hearing, movement, and other Activities of Daily Living (ADLs). Data related to sensory symptoms were collected within a one-month period from March 1, 2020, to April 1, 2020.

Grouping of items: After generating items from the literature and interviews, they were combined and carefully selected to form a large pool of items categorised into 11 domains.

Formation of rough draft (Set 1): Questions were formulated based on the items and relevant terms obtained from the literature and interviews. The questions were designed to address the needs of all types of CP.

Validity Assessment

Content validation: The content validation was conducted using the online Delphi approach (8). The items and domains were entered into an online Google Forms and emailed to the expert panel. The panel of experts, consisting of 10 members, responded to a series of questions (9). It was determined that having more than 10 members in the panel was unnecessary (10).

To represent and identify patient demands, a panel of specialists in the related field with a minimum of 10 years and upto 25 years of clinical experience from various geographical locations was selected. The panel included individuals with qualifications such as Masters in Physiotherapy, Ph.D., PDF, and MBBS, specialising in paediatrics and physiotherapy. Most of the experts held positions as professors in medical institutions. The study was conducted in three rounds, as shown in (Table/Fig 1), with each round being analysed. The responses from the second and third rounds were assessed for relevancy (importance of the question for the tool), clarity (the clarity of language), and necessity (the importance of each question). The answers were graded on a 4-point Likert scale, with the following marking criteria:

1. Not necessary/Not relevant/Not clear,
2. Useful but not essential/The item needs some revision (for relevancy)/The item needs some revision (for clarity),
3. Essential/Relevant but needs minor revision/Clear but needs minor revision,
4. Very essential/Very relevant/Very clear.

Content with ratings of one and two were considered invalid, while content with ratings of three and four were deemed acceptable.

Pilot study: After the content validation, the SOM was further pilot-tested to assess practical challenges, understandability, word interchange usage, time requirements, grading criteria, and final interpretations. Children with hypoxic CP between the ages of 3 and 14 years were recruited for the study. A sample size of 20 was determined to be sufficient for the pilot study, considering the low prevalence of the condition and the impact of the COVID pandemic. This sample size was recommended 6by Julious SA (11). The pilot study involving CP children was completed within 15 days, with the targeted sample of 20 participants successfully obtained.

Scoring: The scoring criteria were developed based on the opinions of experts who conducted the content validation of items, previous research on existing tools, and the practical insights gained from the pilot study.

Face validity: Face validity was assessed through face-to-face interviews with 10 clinicians who intended to utilise the instrument in their practice. Factors such as clarity, unambiguity, logical scoring, interpretations, and relevance were considered [12,13]. An interview with all 10 physiotherapists was scheduled for September 15, 2021. Assistant professors with master’s degrees in their respective subjects and 5-12 years of clinical experience served as the subject matter experts for face validity. Each expert was provided with a form to fill out, which consisted of closed-ended questions with a yes/no response option. A score of 1 was assigned for “Yes” and 0 for “No,” thereby converting qualitative assessments into quantitative scores.

Concurrent validity: The concurrent validity of the SOM was evaluated by comparing it with the Short Sensory Profile (SSP) as a criteria measure. The study included the participation of 20 children with CP, ranging in age from 3 to 14 years. Both the SSP and the newly designed SOM scales were used to assess sensory issues.


Online Delphi Method

Online Delphi Method: The percent agreement for CVR and item-level CVI was calculated (Table/Fig 2) (14). For the development of a new tool, a CVI cut-off score of 0.78 was considered acceptable when the number of panel experts was 9 or above (15). The overall scale-level CVI for the 64-item scale was 0.890625, which exceeded the acceptable limit (16). Kappa statistics for all items ranged from 0.79 to 1, indicating excellent content validity for the instrument (17).

Pilot Testing: The time taken for the first caregiver of a CP child recruited for the pilot study was 40 minutes, and this decreased by 20 minutes for the last caregiver. A practical challenge identified during the pilot study was that certain questions were misleading regarding motor power, necessitating their removal. Some patients did not achieve certain milestones, and one question in the auditory domain appeared to be repeated (Table/Fig 3).

Scoring: The SOM was scored on a 5-point ordinal scale to represent the level of sensory involvement in children with CP (18),(19).

Face Validity: The lowest allowable item-level Face Validity Index (FVI) value was set at 0.80 (15). For all questions, item-level FVI values ranged from 0.9 to 1. The experts’ reactions showed a 96% agreement, indicating complete agreement. All questions in the questionnaire were retained (Table/Fig 4) (20),(21).

Concurrent Validity: The concurrent validity of the SOM with the criterion measure, the SSP, was reported as 0.866 by the Spearman rank correlation coefficient (ρ), indicating excellent concurrent validity.

Correlation Graph: A regression line was constructed using the least squares approach to represent the SOM values (22). There were not many data points falling above or below the line of best fit. The value of r was 0.793 with a p-value of 0.023, indicating a strong positive correlation between the SOM and SP scales (Table/Fig 5).


Somatosensory information plays a crucial role in motor learning and the development of cognitive skills. In neurodevelopmental disorders, especially CP, abnormalities in somatosensory processing have been associated with deficits in communicative, motor, and social skills. Clinical research suggests that sensory processing abnormalities contribute to motor planning and execution deficits, affecting postural control and motor performance in CP (3).

Studies on somatosensory evoked potentials have shown a strong correlation between the severity of motor deficits and the extent of sensory loss (23).

Sensory abnormalities in children with CP are often caused by white matter lesions, which are present in 45% of cases (5). These sensory processing challenges affect the child’s ability to participate in the educational environment and process auditory, visual, and tactile information (24).

While there are 21 tools available for assessing sensory processing in children between the ages of 3-11, only 15 of them are widely supported by psychometric research, mostly conducted in the United States (US). However, none of these tools specifically target children with CP (25). The quality of an assessment instrument, such as a questionnaire, is a fundamental aspect of research evaluation (26). Validity, including face validity and construct validity, is crucial in determining the accuracy and consistency of the collected data (27),(28),(29).

CVR analysis, conducted by Lawshe CH, was used to determine the validity of each attribute in the CVR database (1975). This analysis determined whether an attribute was acceptable or invalid based on its CVR value (30). The newly developed SOM is a unique tool for documenting sensory symptoms in children with CP. Three sources were used to identify the items in the scale, and all items were assessed using the consumer-provider model. Face validity, construct validity, and other forms of validity testing yielded positive results, indicating that the instrument is valid for documenting sensory impairments in children with CP.

The SOM is an ordinal scale that can be converted into an interval scale to calculate percentage scores for each domain. It can also be translated into Indian regional languages to enhance understanding and comprehensibility. A new column called “milestone not achieved” can be added to include items that were eliminated due to failure to achieve the specific milestones. The newly designed scale has the potential to successfully document significant changes in clinical outcomes for children with CP in India, with a focus on sensory impairment.


1. Construct validation was not investigated in the study, as the need to generate construct validity only arises when traditional validation approaches are ineffective.
2. At the time of data collection, the type of CP was not documented, despite the fact that sensory impairment is present in all forms of CP (29).


The SOM scale has been developed as a valid measure for children with CP. Experts in relevant fields such as paediatricians, neuro-paediatricians, and physiotherapists (paediatrics) validated the items and the overall measure. The instrument was also reviewed by clinical physiotherapists to ensure its appropriateness. It demonstrated excellent concurrent validity when compared to the SSP. This is the first measurement scale developed in India specifically for assessing sensory impairments in CP children.
