OTHER

each participant did three conditions: 1. holding nothing (unloaded). 2. holding an infant mannequin in arms(arms). 3. holding an infant mannequin in the baby carrier(carriers).

Device: Baby carrier; Device: Biodex Balance System; Other: Infant mannequin; Device: Biodex gait trainer 2 TM

Interventions

Baby carrier DEVICE

* It is made in china. * It is made of Cotton-Polyester. * It has 3 belts - 2 shoulder belts and one waist belt for superior lumbar support. Shoulder straps are padded and adjustable for the parent's comfort. It has webbing straps for shoulder and waist strap adjustment. * It is suitable for newborn to 12-months baby * It is available online at babyshopstores "https://www.babyshopstores.com/"

Biodex Balance System DEVICE

* The Biodex Balance System SD (The Biodex Balance System SD Model 945-300, 115 VAC, Shirley, NY, USA) is used to assess the balance in this study. * It is an objective device that measures dynamic postural stability. It uses a circular platform that allows up to 20˚of of platform tilt in a 360˚ range of motion. * The measures of postural stability score for BBS are the Overall Stability Index (OSI), Medial-Lateral Stability Index (MLSI), and Anterior-Posterior Stability Index (APSI). These indices are standard deviations that assess the path of sway around the zero point from the center of the platform and are measured in degrees. A high score in these stability indices indicates poor balance.

Infant mannequin OTHER

The mannequin infant has 3 Kg which corresponds to the infant's age from birth until 1month. This weight is selected as it corresponds to the age at which the infants are frequently carried by the mother .

Biodex gait trainer 2 TM DEVICE

Gait Trainer 2™ ( model number:950-385, 115 VAC 50/60 Hz, made in the USA) is used for participants to walk on as walking is one of the most common daily life activities. because caregivers commonly walk while carrying their infants as it has a calming effect on crying infants It consists of : * Display: Use Audio and Visual Biofeedback - real-time biofeedback prompts patients into a proper gait pattern. * Heart Rate Monitoring * Handrail * Open Platform
