Reliability and Validity of Modified Four Square Step Test

• Conditions: Total Hip Arthroplasty

• Registration Number: NCT05054192
• Lead Sponsor: Afyonkarahisar Health Sciences University

Brief Summary

Functional improvements are reached in patients with primary total hip arthroplasty compared to the pre-operative term however some problems as continued range of motion limitations, loss of joint proprioception sensation, and resulting balance and gait disorders may result in failure of the Four Square Step Test. Therefore, the need for the apply of the Modified Four Square Step Test in individuals with primary THA is necessary. The aim of this study is to evaluate the test-retest reliability, concurrent validity and minimal detectable change of the Modified Four Square Step Test in individuals with primary total hip arthroplasty.

Detailed Description

Roos et al. improved the Modified Four-Square Step Test to complete the test by stroke patients and not to fall due to practices of the test while performing the test. The Modified Four Square Step Test variates from the The Four Square Step Test is that the person is not asked to look ahead during the test, and instead of using a cane, tapes are used to prevent people from losing their balance by tripping over the obstacle. Thus, although the height of the obstacle is reduced, the boundaries of the obstacle are preserved.

Primary Outcome Measures

Name	Time	Method
Dynamic Balance	6 minutes	Dynamic balance is the ability of an object to balance while in motion or switching between positions. Dynamic balance will be evaluated with the modified four square step test. The duration as second will be recorded.

Secondary Outcome Measures

Name	Time	Method
Dynamic Balance	25 minutes	Dynamic balance will be evaluated with the Berg Balance Test. The scores from the test will be recorded.
