Brief summary: To investigate the relationship between smartphone addiction and isometric rotator cuff muscles strength among adults

Detailed description: Smartphones play an important role in human life because they are used for communication, accessing the internet, and gaming. The rate of smartphone usage has increased over the last decade, as has the duration and frequency of use. according to one study, 79 percent of people aged 18 to 44 spent almost all of their time on their smartphones, with only two hours of the day spent without one.

No previous study has found a link between smartphone addiction and isometric Rotator Cuff muscular strength, to the authors' knowledge. Therefore, the primary purpose of this study will be to determine the relationship between smartphone addiction and isometric rotator cuff muscles strength.

Eligibility criteria: Inclusion Criteria:

- 1- This study will comprise healthy volunteers between the ages of 18 and 30 who needed to use a smart phone.

2- Subjects who put in more than 4 hours per day using smartphone.

Exclusion Criteria:

* Patients will rule out if

  1. They had any medical condition that could cause shoulder pain (such as impingement, subacromial bursitis, rotator cuff damage, or traumatic or degenerative supraspinatus tendonitis).
  2. Anyone with a positive Neer sign, a positive Hawkins sign, discomfort during shoulder elevation, pain at the location of the rotator cuff tendon, pain with resisted isometric shoulder abduction, or a history of pain in the C5 dermatome will be ruled out.
  3. Any individual who had previously suffered a musculoskeletal injury or surgery that could have influenced the measurement will be also eliminated.
