An interventional study of Whole body vibration and Sham Whole body vibration in Smart Phone Addiction, sponsored by Cairo University. Completed at 1 site in Egypt. Open to female participants aged 18 Years to 25 Years. Per ClinicalTrials.gov, last updated 2025-12-16.
Sponsored by Cairo University · Not applicable, Interventional, and Treatment
Young adults have a high prevalence of smartphone addiction. Many adolescents use their smartphones extensively for communication, which starts out as a habit but eventually turns into an addiction. Numerous studies have shown that adolescents use social media for roughly ten hours every day.
Cairo University is the lead sponsor of 4,780 studies on the registry; 1,427 are open to participants now.
Of its 36 completed or terminated interventional studies of FDA-regulated products, 5 (14%) have results posted.

Exclusion Criteria:
Whole body vibration (WBV) group will receive vibration on the platform for 20 repetitions in 2 sets with 2 minutes rest between sets in addition to strengthening exercises to the hand muscles.
Device: Whole body vibration · Other: Strengthening exercises
participants will receive WBV with the device turned off in addition to strengthening exercises to the hand muscles.
Device: Sham Whole body vibration · Other: Strengthening exercises
Participants will be asked to sit on an chair without armrests close to the platform and will be asked to perform 90° shoulder flexion, bend both elbows slightly, flex the trunk forwards and place both hands on the platform.
Participants will receive the vibration with the device turned off.
Participants will use elastic resistance for the finger extension and flexion exercises, and ball to strength wrist flexors for two sets of 10 repetitions within a training session.
Hand grip strength
Participants will be asked to perform maximum hand grip with the dominant hand with hold for 5 seconds, for three repetitions using the hand held dynamometer (dynamometer, Jamar, United States), a 60 seconds rest interval will be planned in between the repetitions. The mean of the three repetitions will used for calculation of hand grip strength.
Time frame: 4 weeks
pinch strength
The participant will be asked to sit comfortably, with the pinch gauge between the index and middle fingers, and thumb, with the tested arm at the side with the elbow flexed 90 degrees. After five seconds of holding the pinch with full force, take a reading, repeat three times.
Time frame: 4 weeks
Muscle activity of flexor carpi radialis muscle
Muscle activity will be measured utilizing electromyography (EMG) using the Delsys Trigno (DST01) system for flexor carpi radialis muscle.
Time frame: 4 weeks
Muscle activity for flexor carpi ulnaris muscle
Muscle activity will be measured utilizing electromyography (EMG) using the Delsys Trigno (DST01) system for flexor carpi ulnaris muscle.
Time frame: 4 weeks
Muscle activity for extensor digitorum communis muscle
Muscle activity will be measured utilizing electromyography (EMG) using the Delsys Trigno (DST01) system for extensor digitorum communis muscle.
Time frame: 4 weeks
Upper limb function
The upper limb function will be assessed by using the Arms, Shoulders and Hands Disability Questionnaire (DASH) Quick, which is a validated and widely used 11-item questionnaire that evaluates certain impairments and symptoms in the upper limb. the score ranged from 0 to 100, the lower the score, the greater the results. While, higher scores represent the worst results.
Time frame: 4 weeks
