The Effect of Upper Extremity Strengthening on Functionality, Muscle Strength and Trunk in Children With Cerebral Palsy

Cerebral Palsy (CP) is an activity limitation, movement and posture deficiencies in early stage of life. In 80% of these children, upper extremity (UE) dysfunctions are observed, which leads to loss of quality of life, resulting in limited participation in activities of daily living (ADL). When the hands are affected in UE, fine motor skills such as grasping, writing and object manipulation are usually limited. This results in inadequate use of the extremities in functional activities. Although all children with CP are known to be affected by UE, studies in terms of physiotherapy and rehabilitation methods mostly focused on children with hemiparetic CP. Similar problems are observed in children with bilateral involvement. However, a wide variation is observed in the bimanual performance of children with hemiparetic and bilateral involvement. Studies evaluating UE activities in children with CP; emphasized that the inability to manipulate objects manually is one of the most important reasons for the restriction of participation in ADLs. Physiotherapy and rehabilitation programs include many neurodevelopmental treatment approaches including stretching, strengthening, positioning, splinting, casting, orthosis selection and movement facilitation. However, it is known that studies investigating the current efficacy of these treatments on UE functions mostly focus on unilateral CP. Interventions that focus on improving UE functions in children with bilateral CP are limited. In UE rehabilitation in bilateral CP; states that target-focused therapy, bimanual intensive task specific training programs and trainings such as HABIT (intensive bimanual training of the upper extremity) involving the lower extremity have been used, but there is only evidence for HABIT-ILE (HABIT involving the lower extremity). In the literature, it is observed that strengthening training with the Proprioceptive Neuromuscular Facilitation (PNF) method, which makes a significant contribution to muscle
