Ultrasound therapy is one of the commonest and most popular modality used for tissue healing, pain reduction, tissue extensibility and in inflammation by physiotherapists all around the globe. Various sensitivity tests on peripheral nerves are done with ultrasound therapy, yet conclusions are still skeptical, which makes it inconclusive in progressing the modality further into management of nerve disorders. This study aimed to analyze efficiency of therapeutic ultrasound in influencing ulnar nerve conduction velocity. To Analyze the effect of ultrasound therapy in altering motor nerve conduction velocity of ulnar nerve with two therapeutic frequencies. 40 healthy individuals were included according to the selection criteria and they were explained about safety and simplicity of procedure and informed consent was obtained. All the participants were randomly assigned into two groups as 20 in each group. Group-A was given ultrasound therapy at specific site of elbow to target the ulnar nerve with 1MHz frequency and Group–B followed the same procedure with 3MHz frequency. Pre and Post to ultrasound therapy application Motor Nerve Conduction Velocity (MNCV) of ulnar nerve were recorded for both the groups. The posttest mean of MNCV for forearm segment and arm segment for Group A and Group B showed statistically significant difference (P Value <0.001).The analysis done by the statistical data also revealed that the MNCV at forearm segment showed an increase in velocity compared to its pretest values, whereas the post MNCV values at arm component showed a decrease in velocity when compared to its pretest values. Among comparison the data within the groups it is evident that group A with 1 MHz of ultrasound sonification is more capable of altering the MNCV values in comparison with the 3MHz. frequency. Findings of this study conclude that ultrasound therapy can be used effectively in altering conduction velocity of a nerve and it has a potential ability to facilitate or inhibit a nerve physiological function.
Background: Hand function is an important aspect of most of the activities of daily living. There are many conditions that cause direct impact on hand function but few of musculoskeletal conations indirectly influence the hand function but often ignored in rehabilitation. Objective: The aims of this study were to analyse the hand function among lateral epicondylitis (LE) patients and identify the influence of various parameters (Age, dominance, pain, range of motion (ROM), and chronicity) that may influence the hand function. Methods: Eighty six LE patients participated in this cross sectional study. The hand function was assessed using Perdue peg board along with various other parameters like age, dominance, pain, range of motion, and chronicity. Results: There was a significant difference between the hand function of affected and unaffected extremity (p<0.001, effect size of 0.425). Pain severity, chronicity of LE and wrist extension was strongly related to hand function with R value of -0.910, -0.788 and 0.698 respectively. Conclusions: The results highlight the possible hand function compromise among patients with LE. Out of all the assessed parameters pain severity, wrist extension ROM and chronicity of condition were associated with hand function compromise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
