Brief Summary

To investigate the correlation between shoulder lateral rotators strength (LRS) and hand grip strength (HGS) at different shoulder positions in patients following arthroscopic Bankart repair surgery for anterior shoulder instability.

Conditions

Arthroscopic Bankart Repair; Arthroscopic Shoulder Surgery; Hand Grip Strength; Rotator Cuff Strength

Keywords

Shoulder Instability; Arthroscopic Bankart Repair; Lateral Rotator Strength; Hand Grip Strength

Outcome Measures

Primary Outcomes (1)

• Correlation between shoulder lateral rotator strength (LRS) and hand grip strength (HGS)

  LRS and HGS will be measured isometrically using handheld dynamometer and hand grip dynamometer in three standardized shoulder positions. The correlation between these two variables will be analyzed to assess the neuromuscular relationship postoperatively.

  6-12 months post arthroscopic bankart repair

Interventions

handheld dynamometer and hand grip dynamometer DEVICE

using handheld dynamometer and hand grip dynamometer to test the strength of the hand grip and lateral rotators of the shoulder

Eligibility Criteria

• Age: 18 Years - 40 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

15 patients aged 18 to 40 years Who underwent arthroscopic Bankart repair surgery Recruited from the outpatient physical therapy unit at International Mansoura Hospital Assessed 6 to 12 months postoperatively All had undergone a standardized 6-month physical therapy program Inclusion criteria ensured full or nearly full ROM and absence of shoulder pain Patients had no other musculoskeletal or neurological impairments affecting the shoulder or contralateral upper limb.

You may qualify if:

• Patients with arthroscopic Bankart repair surgery.
• Patients have passed 6 months after surgery.
• Patients have not surpassed 12 months from surgery
• Age of the patient ranged from 18 to 40 years to avoid including people with potential degenerative rotator cuff tears.
• Patients immediately started physical therapy program after surgery for 6 months.
• Nearly or complete full ROM.
• Absence of shoulder pain.
• Normal contralateral arm without previous surgeries.

You may not qualify if:

• Other associated surgeries such as slap repair or large humeral bone defect requiring remplissage.
• Moderate to severe shoulder pain.
• Incomplete ROM.
• Presence of nerve injury after the initial trauma.
• Past history of other previous surgeries on the affected limb.
• Any surgery or musculoskeletal disorder related to the neck or the contralateral upper limb.
