Premature birth, low birth weight, and a history of neonatal intensive care history are significant risk factors associated with long-term neurodevelopmental adverse outcomes in infants. Family-centered early intervention programs play a critical role in minimizing the impact of these risks and optimizing developmental potential. Currently, telerehabilitation (TR) has emerged as a cost-effective solution that facilitates access to early intervention services. However, there is limited literature directly comparing the efficacy and feasibility of synchronous (real-time) and asynchronous (store-and-forward) parent coaching-based TR models specifically within the at-risk infant population. The primary objective of this project is to comparatively examine the effects of synchronous and asynchronous TR programs on motor development levels, individualized goal attainment, and parental self-efficacy in infants aged 6-9 months (corrected age) at risk of developmental delay, against a standard home program (control group). Designed as a randomized controlled trial, the study will include 45 high-risk infants meeting the inclusion criteria, who will be randomly allocated into three groups: Synchronous TR, Asynchronous TR, and Control. In the Synchronous group, parents will receive real-time coaching via video conferencing for 12 weeks, whereas the Asynchronous group process will be managed through video analysis and delayed feedback mechanisms. The Control group will be provided with standard digital educational materials. The primary outcome measures of the study include Goal Attainment Scaling (GAS) scores, the Parental Self-Efficacy Instrument, and the Parenting Stress Index. Secondary measures will include the Bayley Scales of Infant and Toddler Development (Bayley-IV), the Alberta Infant Motor Scale (AIMS), and the Hammersmith Infant Neurological Examination (HINE). Data will be collected at baseline (T0) and post-intervention (T1) by an assessor blinded to group allocation. The findings obtained from this study aim to demonstrate the clinical efficacy of different TR models, thereby providing guidance for the planning and dissemination of remote healthcare services for high-risk infants.

A 12-week remote physiotherapy program based on a 'parent coaching' model delivered via real-time video conferencing (Zoom). The intervention consists of weekly 45-minute sessions where the physiotherapist acts as a coach, providing live verbal and visual guidance to parents as the primary implementers of the intervention. Activities are integrated into the infant's natural daily routines (play, feeding, care). Pre-session standardized guidance (camera positioning, infant readiness) is provided via WhatsApp. Clinical progress is monitored through weekly evaluation and updating of Goal Attainment Scaling (GAS) objectives tailored to the infant's developmental needs.
A 12-week remote physiotherapy program based on a parent coaching model using a delayed feedback principle. To ensure therapeutic intensity equivalent to synchronous sessions, parents record and submit 10-15 minutes of video clips weekly through secure, end-to-end encrypted messaging. These clips demonstrate intervention activities integrated into daily routines (play, feeding, care). The physiotherapist performs a detailed analysis of handling techniques and movement quality, providing feedback via recorded demonstration videos (using a model doll or the therapist) to correct or reinforce motor patterns. Each weekly cycle includes evaluating Goal Attainment Scaling (GAS) objectives and updating motor strategies based on the infant's current developmental needs.

Goal Attainment Scaling
Goal Attainment Scaling (GAS) is a standardized method used to evaluate the achievement of individualized treatment goals in pediatric rehabilitation. For each infant, 3 to 5 SMART (specific, measurable, attainable, relevant, and time-bound) goals are collaboratively established by the physiotherapist and the family. Each goal is scored on a 5-point scale: -2 (baseline level), -1 (less than expected), 0 (expected outcome), +1 (more than expected), and +2 (much more than expected). The raw scores are converted into a standardized T-score using the formula with a mean of 50 and a standard deviation of 10. A T-score of 50 or higher indicates that the intervention has successfully met or exceeded the expected goals.

Parental Self-Efficacy Instrument for Children with Disabilities
The Parental Self-Efficacy Scale, developed by Guimond et al. (2005) and adapted into Turkish by Cavkaytar et al. (2014), assesses the self-efficacy perceptions of parents of children with disabilities regarding their caregiving and child-rearing capacities. The scale consists of 17 items rated on a 5-point Likert-type scale. It is primarily administered as a self-report tool, with researchers providing assistance (reading items) for illiterate participants if necessary. The Turkish version demonstrated high internal consistency (Cronbach's Alpha = 0.95) and test-retest reliability (r = 0.79). Total scores range from 17 to 85, where higher scores indicate a greater sense of parenting competence and self-efficacy in their roles.

Parenting Stress Index - Short Form (PSI-SF)
The Parenting Stress Index - Short Form (PSI-SF), originally developed by Abidin (1983) and validated in Turkish by Mert et al. (2008), is a 36-item self-report instrument designed to assess stress within the parent-child system. It consists of three subscales (12 items each): Parental Distress, Parent-Child Dysfunctional Interaction, and Difficult Child. The Total Stress score is calculated by summing these three subscale scores. Total scores range from 36 to 180, where higher scores represent higher levels of perceived parenting stress. The Turkish version demonstrated internal consistency (Cronbach's Alpha = 0.71 for Total Stress; 0.76-0.81 for subscales) and high test-retest reliability (r = 0.88).

Hammersmith Infant Neurological Examination
The Hammersmith Infant Neurological Examination (HINE) is a standardized, quantitative tool for the neurological assessment of infants aged 2 to 24 months. It comprises three sections: (1) a 26-item neurological examination assessing cranial nerve function, posture, movement quality, muscle tone, and reflexes; (2) an 8-item assessment of developmental motor milestones; and (3) a 3-item behavioral assessment. The total neurological score is derived from the 26 items in the first section, with a maximum possible score of 78. Higher scores indicate better neurological development and maturity.

Bayley Scales of Infant and Toddler Development, Fourth Edition
The Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-IV) is a comprehensive assessment used to evaluate developmental functioning in infants and toddlers aged 16 days to 42 months. It covers five primary domains: Cognitive, Language (Receptive and Expressive), Motor (Fine and Gross), Social-Emotional, and Adaptive Behavior. The assessment involves interactive tasks with the child and caregiver questionnaires. Standardized composite scores are calculated for each domain, with scores below the 10th percentile indicating a risk of developmental delay. For this study, all assessments will be conducted by certified researchers to ensure standardized administration and scoring.

Alberta Infant Motor Scale
The Alberta Infant Motor Scale (AIMS), developed by Piper and Darrah (1992), is a norm-referenced standardized instrument used to assess the gross motor development of infants from birth through independent walking (approx. 18 months). It consists of 58 items distributed across four postural positions: prone (21), supine (9), sitting (12), and standing (16). Scoring is based on clinical observation of weight-bearing, postural alignment, and anti-gravity movements. The total score ranges from 0 to 58, where higher scores indicate more advanced gross motor maturation (Piper \& Darrah, 1992; Eliks et al., 2022).

Telehealth Usability Questionnaire
The Telehealth Usability Questionnaire (TUQ), developed by Parmanto et al. (2016) and validated in Turkish (Ozden et al., 2021), is a 21-item instrument designed to evaluate the quality of telerehabilitation services, software, and systems. It assesses six domains: usefulness, ease of use and learnability, interface quality, interaction quality, reliability, and satisfaction. Items are rated on a 7-point Likert scale (1=Strongly Disagree, 7=Strongly Agree). Total scores range from 21 to 147, where higher scores indicate greater usability and satisfaction with the telehealth system. This scale will be used to compare the technical infrastructure performance and family-system interaction levels for both synchronous and asynchronous models.
