About this trial
The goal of this clinical trial is to investigate the effects of foot core exercises on lower extremity muscle strength, viscoelastic properties, functional parameters, foot and ankle posture, balance, and the morphological characteristics of periarticular structures of the foot and ankle in individuals with total hip arthroplasty. The main questions it aims to answer are:
* Does foot core exercises affect morphological characteristics of the periarticular structures surrounding the foot and ankle? * Does foot core exercises affect viscoelastic properties of the periarticular structures surrounding the foot and ankle? * Does foot core exercises affect lower extremity muscle strength? * Does foot core exercises affect lower extremity functional parameters and balance in individuals with total hip arthroplasty?
The researchers will compare the group performing foot core exercises with the group performing routine hip exercises that do not include foot core exercises.
Participitants will:
* Participants will receive an exercise log after a specialist physiotherapist demonstrates the exercises in practice at the third postoperative mounth. * Visit the clinic every two months from postoperative mounth 3 to month 7 for routine follow-ups and progression of exercises. * Except for the control sessions held every two mounths, patients will be followed up through weekly phone calls. * Participants will complete an exercise diary indicating that they performed the exercises prescribed for each week, and they will bring their diaries with them to the follow-up sessions.

Trial outcomes
Primary outcomes
1
Ultrasonographic muscle thickness of foot and ankle periarticular structures
The muscle thickness of the foot and ankle periarticular structures will be evaluated using ultrasonography. Ultrasonographic examinations will be performed in accordance with the EURO-MUSCULUS/USPRM foot and ankle protocols (26, 27), using a Clarius ultrasound system (Clarius Mobile Health, 205-2980 Virtual Way, Vancouver, British Columbia, Canada) and a 4-13 MHz linear transducer. All measurements will be conducted by researchers who have received training in ultrasonographic imaging.
Time frame
From enrollment to the end of treatment at 12 weeks2
Ultrasonographic cross-sectional area of foot and ankle periarticular structures
The muscle cross-sectional area of the foot and ankle periarticular structures will be evaluated using ultrasonography. Ultrasonographic examinations will be performed in accordance with the EURO-MUSCULUS/USPRM foot and ankle protocols (26, 27), using a Clarius ultrasound system (Clarius Mobile Health, 205-2980 Virtual Way, Vancouver, British Columbia, Canada) and a 4-13 MHz linear transducer. All measurements will be conducted by researchers who have received training in ultrasonographic imaging.
Time frame
From enrollment to the end of treatment at 12 weeks3
Tone (frequency) of foot and ankle periarticular structures
The MyotonPro device (Myoton AS, Estonia) will be used to evaluate the muscle tone (frequency) (F) of the gastrocnemius medialis (GM),gastrocnemius lateralis (GL) , tibialis anterior (TA), peroneus longus (PL) muscles, the Achilles tendon (AT), and the plantar fascia (PF). Frequency (F) characterizes muscle tone and is reffered as Hz (Hertz). All measurements will be performed on both extremities. To ensure standardization, appropriate anatomical reference points for each structure will be marked prior to measurement
Time frame
From enrollment to the end of treatment at 12 weeks4
Ultrasonographic tendon morphology of foot and ankle segments
The tendon morphology of the foot and ankle muscles will be evaluated using ultrasonography. Ultrasonographic examinations will be performed in accordance with the EURO-MUSCULUS/USPRM foot and ankle protocols (26, 27), using a Clarius ultrasound system (Clarius Mobile Health, 205-2980 Virtual Way, Vancouver, British Columbia, Canada) and a 4-13 MHz linear transducer. All measurements will be conducted by researchers who have received training in ultrasonographic imaging.
Time frame
From enrollment to the end of treatment at 12 weeksSecondary outcomes
1
Evaluation of lower extremity alignment
Lower extremity alignment will be assessed by calculating the Q angle. To evaluate the Q angle, participants will be asked to lie in the supine position with the knee joint in full extension. The Q angle will be measured using a goniometer as the angle formed between a line drawn from the anterior superior iliac spine (ASIS) to the midpoint of the patella and a line drawn from the midpoint of the patella to the tibial tuberosity, and the values will be recorded
Time frame
From enrollment to the end of treatment at 12 weeks2
Navicular height during weight-bearing condition
It is a widely used test for evaluating foot biomechanics disorders and related musculoskeletal problems, used to assess foot arch structure and pronation level (38). The navicular height will be measured in a barefoot full weight-bearing position. The vertical distance between the navicular tuberosity and the ground will be assessed.
Time frame
From enrollment to the end of treatment at 12 weeks3
Assessment of Hip Flexor Muscle Strength
Hip flexion muscle strength will be assessed using a hand-held dynamometer (Lafayette Instrument, Lafayette, IN). The maximal isometric strength will be recorded as Newton (N)
Time frame
From enrollment to the end of treatment at 12 weeks4
Assessment of Balance
Functional mobility and dynamic balance will be assessed using the Timed Up and Go (TUG) test. It is a simple and reliable test that is frequently used in older adults to assess an individual's mobility, balance, walking ability, and risk of falling. The Time Up Go test is commonly used in individuals who have undergone total hip arthroplasty, and it has been shown to have high test-retest reliability and good construct validity in this population
