Intervention / Comparator Agent

Type	Name	Details
Intervention	median nerve mobilization on hand grip strength,pinch strength and motor nerve conduction velocity	The intervention is of 4 weeks Mobilization Techniques A Nerve Sliding Technique Weeks 1–2 Alternating movement between wrist and finger extension and cervical side flexion Aims to facilitate excursion of the median nerve without increasing strain Procedure: 2 sets of 10–15 repetitions per session Performed rhythmically and pain-free Adjusted if tension or discomfort occurs B. Nerve Tension Technique Weeks 3–4 Aimed at improving nerve compliance and tension tolerance Cervical spine held in lateral flexion away from the treated side End-range stretch applied at wrist and fingers Procedure: 2 sets of 8–10 repetitions Each repetition includes a 3–5 second hold at end range Discontinued if symptoms worsen

Brief Summary

Background: Excessive smartphone usage has been linked to musculoskeletal issues, including decreased hand grip strength, pinch strength, median nerve conduction velocity due to repetitive stress on the median nerve. Median nerve mobilization is a therapeutic technique that may improve nerve function and muscle performance. However its effectiveness in individuals with smartphone overuse remains under explored.

Objective: This study aimed to Effectiveness of Median Nerve Mobilization on hand Grip Strength, pinch strength and motor nerve conduction velocity in College Students with smartphone overuse

Methods: A quasi-experimental study will be conducted at Maharishi Markandeshwar Deemed to be University. College students aged 18–30 years with smartphone overuse more than or equal to 4 hours/day and reduced hand grip strength pinch strength and motor nerve conduction velocity will be measured. Median nerve mobilization ULTT1 will be administered three times per week for four weeks.

Data Analysis: Data will be analyzed using SPSS software version 20. Based on sample size, normality will be assessed using Kolmogorov or Shapiro-wilk test will be used. Depends on normality, parametric and non-parametric tests will be applied. A significance level of p less than 0.05 will be considered statistically significant.
