Most of the CTSs are idiopathic and are provoked by repetitive grasping and manipulating activities, and the exposure can be cumulative. Orthotic splinting is prescribed both pre-and postsurgical but essentially in pre-surgical situation. The importance of wrist orthotic splints in non-operative treatment for carpal tunnel syndrome is a known scenario. Also evidentially it has a standard of care despite having varying rates of success. The aim and objective of orthotic splinting is to immobilize the wrist to stop flexion and maintain low range of wrist motion which help to decrease inflammation. CTS splint may be applied to dorsal side or in volar for maintaining wrist in a neutral position. The general recommendation is to wear a wrist immobilization orthotic splint as night splint. Splint kinematics and kinetics for biomechanical analyzing principles are essential to understand the principles involved in the various standard design, construction, and fitting of CTS splint. Application of orthotic biomechanics is for possessing a specific understanding of orthotic splinting function as per clinical orthotic assessment.

The purpose of the study is to determine Impact of Functional Foot Orthosis on Vertical Ground Reaction Force and Pain in Persons with Plantar Fasciitis.There was significant improvement in pain as well as ground reaction force by using functional foot orthosis. Vertical ground reaction forces were significantly different at loading response and at terminal stance after use of the orthosis than before but no significant change was seen at midstance. Pain ratings mean in symptomatic foot measured by the Visual analog scale were significantly less than before use of the orthosis. It may be concluded that Functional foot orthosis significantly reduces pain experienced during walking and normalizes the vertical ground reaction force in subjects with plantar fasciitis.

Numerous means to suspend below-knee (BK) prostheses have been developed. Although suspension systems generally used for BK prostheses have similar functions, choices for prescription are not totally clear. Patellar tendon bearing (PTB) suspension principles are effective with many patients; however, those with short limbs may not achieve complication-free suspension. The fact that variations of BK suspensions continue to appear suggests that a universal suspension system is not yet available. Objective: To find out the effect of two types of suspension system on gait parameters and locomotor capabilities index in subject with unilateral transtibial amputee. Study design: Single study with post experimental design. Methods and measures: Two different suspension systems such as supracondylar and cuff suspension for below knee prostheses were tested on 30 adults with unilateral transtibial amputees. All su...

Orthotic treatment’s primary aim is to stop further curve progression. The aim of this study is to find the effect in treating congenital scoliosis with single-level hemi vertebrae using orthotic interventions on curve correction and its cardio respiratory functions. Case description and method: A 14 years old with single-level hemi-vertebrae related congenital scoliosis tookunder non-operative treatment at his body with an average supplement period of 2 years. Spinal orthosis (moulded-TLSO, high Profile Boston Brace) was fitted on the patient according to SRS guidelines. Breathe cardio-respiratory data analysis and the metabolic data analysis are done through the COSMED-Srl-Italy,K4B2 respectively. Finding: The cardio-respiratory table and graph established a significantly better result in congenital scoliosis with spinal orthosi...

The prevalence rate of the CTS to be present in 3.8% of the general population. Material & Methodology: 30 subjects with carpal tunnel syndrome were included in this study by Convenience sample method. The subjects were divided into two groups; Group A Volar wrist hand splint and Group B Dorsal hand splint. EMG was measured by Electronic hand disability evaluation machine and force was measured by hand held dynamometer and pinchometer. First baseline data was collected and during delivery of orthosis immediate data was collected to check immediate effect, and after 6 weeks post data was collected. Results: There was statistically no-significant between the groups at baseline for all outcome parameters, APB & FL muscle, grip force, pinch force, P value was >0.05. There was statist...

This study is aimed developing an appropriate spinal orthosis with dynamic 3-D force application in comparison with Boston brace for correction and estimation of cardiorespiratory functions. Case description and method: 3-D brace was fitted on the case according to a sub classification of the SRS guidelines. Breathe cardio-respiratory data analysis and the metabolic data analysis done through the K4B2, COSMED-Srl-Italy. Results: The averages observed for without brace Boston and 3-D are different in this case, except for VT and O2- expenditure, where though Boston and 3-D shows significant difference with the normal Outcomes and conclusion: This case-report indicates that dynamic 3-D orthosis can be a healthier option for AIS as compared to Boston Brace with a positive range of cardio-respiratory functions.

Objectives: The purpose of the case study is to find out the effect of modified foot orthoses on vertical ground reaction force and quantify the force with and without orthoses Materials and methods: A female subject with unilateral plantar fasciitis in left foot was included in the study. Subject had been provided with modified foot orthosis. Pain was evaluated by using visual analogue scale and vertical ground reaction force was measured by Computer Dyanography Ultraflex Gait Analyser. All measures were acquired before the fabrication of Modified foot orthosis as a baseline data and after that modified foot orthoses was fabricated. Patient was discharged with the orthoses and after 12 weeks of follow up pain and vertical ground reaction force was measured. Results: There was significant improvement in pain as well as ground reaction force by using modified foot orthosis. Vertical ground reaction forces measured during taking baseline data which was different from right foot at loading response, midstance and terminal stance. Follow up data was taken at 12 weeks after use of the orthosis. Pain ratings during baseline was 7.3 and 12 weeks of follow up pain was reduced by 3.8 measured by Visual analog scale.(VAS) Conclusion: Modified foot orthosis significantly reduces pain experienced during walking and normalizes the vertical ground reaction force in patient with unilateral plantar fasciitis.

Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for distances or over terrain which would be fatiguing in a manual wheelchair. They may also be used not just by people with 'traditional' mobility impairments, but also by people with cardiovascular and fatigue-based conditions.

The time series of climate factors: daily evaporation, maximum and minimum temperatures are taken into consideration in variability analysis. All climate data are collected from a specific area of Bihar in India. Fractional Gaussian noise fGn is used here as the reference signal. The climate signal and fGn of same length are combined to produce bivariate complex signal which is decomposed using BEMD into a finite number of sub-band signals named intrinsic mode functions IMFs . Both of climate signal as well as fGn are decomposed together into IMFs. The instantaneous frequencies and Fourier spectrum of IMFs are observed to illustrate the property of BEMD. The lowest frequency oscillation of climate signal represents the annual cycle AC which is an important factor in analyzing climate change and variability. The energies of the fGn's IMFs are used to define the data adaptive threshold to separate AC. The IMFs of climate signal with energy exceeding such threshold are summed up to separate the AC. The interannual distance of climate signal is also illustrated for better understanding of climate change and variability.
