Inclusion criteria

Inclusion criteria: • Age: 18–25 years old, reflecting the demographic most associated with frequent smartphone usage among university students (Berolo et al., 2011). • Mobile Phone Usage: More than 6–8 hours daily, aligning with thresholds used in smartphone (iPhone) addiction and overuse studies (Kwon et al., 2013;AlAbdulwahab et al., 2017). • Health Status: No history of neurological or musculoskeletal disorders, to reduce confounding variables in hand function assessment (Schuhfried et al., 2012; Faul et al., 2007). • Gender: Both male and female participants are eligible, in line with CONSORT recommendations for inclusive research practices (Schulz et al., 2010) • Age matched sedentary adult hand grip strength( hand held dynamometer): in hand uses the cell phone if hand grip strength in male less than 35 kg and female less than 25 kg.

Exclusion criteria

Exclusion criteria: • Neurological Disorders (e.g., stroke, Parkinson’s disease, MS), due to their direct impact on hand function and NMES response (Schuhfried et al., 2012). • Hand Injuries, which may lead to altered baseline dexterity and interfere with study results (Evans, 2005). • Musculoskeletal Disorders (e.g., arthritis), as they affect hand mobility and pain levels (National Research Council & Institute of Medicine, 2001) • Trained individual:prior resistance training experience or consistent dumbbell(Ritti-Dias et al., 2011). • Pregnancy, due to safety concerns related to electrical stimulation, following standard IRB precautions (Faul et al., 2007). • Inability to Commit to Protocol, such as missing sessions or assessments, to ensure reliability and consistency of the intervention (Sanetti & Kratochwill, 2013)
