Introduction

Feeding is a vitally important process in everyday life. It is important for the development of the motor and cognitive functions of the child because a healthy and nutritious food is essential for a normal brain development. Children with cerebral palsy are often diagnosed with poor nutritional status due to their feeding and swallowing problems. When untreated it may lead to growth failure, chronic aspiration, esophagitis, and respiratory infections. It can also impact the child's social, emotional, and cognitive function, and can significantly increase caregiver stress. This article provides an overview of problems and solutions in feeding children with cerebral palsy who experience eating and swallowing difficulties.

Feeding and Swallowing Disorders

Paediatric Feeding Disorder is "an impaired oral intake that is not age-appropriate, and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction."

Dysphagia is a swallowing problem that places the child at risk for aspiration with oral feeding. Aspiration may lead to a life-threatening pulmonary consequences.

Mechanics of Feeding and Swallowing

Feeding

The feeding and eating process takes place in the following four phases:

Phase 1: Opening the mouth

Phase 2: Using utensils, placing the food and liquid in the mouth

Phase 3: Closing the mouth to prevent food or liquid from spilling out

Phase 4: Chewing the food and moving it around to prepare to swallow

Swallowing

Swallowing (deglutition) is the process by which food passes from the mouth through the pharynx and into the oesophagus. It requires coordination with breathing because both of these processes share the same entrance the pharynx . Failure in coordination would result in choking or pulmonary aspiration.

Swallowing occurs in three phases:

Phase 1: Oral phase

Phase 2: Pharyngeal Phase

Phase 3: Oesophageal Phase

Learn about each of the swallowing phases here.

Clinical Signs of Feeding and Swallowing Problems in Cerebral Palsy

Clinical Signs of Feeding Problems

Child's feeding and eating skills may be affected by motor or sensory challenges:

Motor Challenges

• Poor head and/or trunk alignment in midline. The posture can be either too flexed or hyperextended
• Increased muscle tone and involuntary body movements
• Mouth kept open due to an increased or decreased resting tone of the jaw muscles
• Mouth kept firmly closed due to jaw flexion pattern
• Uncoordinated, non graded, or limited movements of the jaw leading to lack of jaw rotation movement and limited or lack of ability to chew
• Passive lips, lack of lip closure and spoon clearance
• Difficulty forming food in the mouth and accumulation of food in the mouth
• Poor saliva control

Sensory Challenges

• Hypersensitivity to certain textures or stimuli ( taste, smell, temperature, visual aspect of food)
• Avoiding behaviour towards a primary caregiver
• Difficulty discriminating tactile sensations (preference for crunchy, chewy foods)
• Difficulty in the perception of gustatory and olfactory stimuli (preference for sour and spicy food and refusal to eat balanced or mild tastes)
• Difficulty accepting new food experiences

Clinical Signs of Swallowing Problems

The signs of swallowing disorder may include the following:

• Lack of stability of the lower jaw not providing base of support for the selective movements of the tongue in all directions. Poor tongue control affects bolus transport, delayed initiation of swallowing, and reduced pharyngeal motility
• Coughing during or right after eating or drinking
• Clearing the throat often
• Irregular swallow
• Having a wet or gurgly voice during or after eating or drinking
• Feeling like something is stuck in the throat or chest
• Needing extra work or time to chew or swallow.
• Having food or liquid leak from the mouth
• Food getting stuck in your mouth.
• Having problem with breathing after meals
• Weight loss

Factors Influencing Child's Feeding and Eating Skills

Environmental factors: environmental distractions decrease concentration on feeding and eating. These distractions include watching television, looking at the computer, bringing toys along during the meal time, chaotic environments with people and loud conversations.

Physical difficulties: the child's oral motor difficulties may prevent the child from eating independently and increase time and child's energy spend on the feeding and eating.

Behavioural factors: caregiver stress and child's negative mood affects feeding and eating. Caregiver calmness and emotional control positively affect child's behaviour.

Healthcare Team Responsibilities

Interdisciplinary team is needed to treat the child with feeding and eating difficulties because different areas of the child's life can be impacted.

Speech-Language Pathologist

Communication, speech and language pathologist is responsible for the following:

• Assessing the function of feeding
• Contributing to the diagnosis and aetiology of dysphagia
• Assessing the protective capacity of the respiratory system
• Indicating alternative ways of eating
• Providing direct and indirect intervention with the patient which include strengthening facial muscles, teaching different strategies to develop sucking, chewing, and drinking skills, tasting new food, and drink with rich flavours, aromas, and modifying food liquid to improve swallowing
• Guiding staff and care givers in better management of the feeding difficulties

Occupational Therapist

The occupational therapy assessment of the child with cerebral palsy's feeding and eating needs, independence and safety, should include the following:

• Motor and sensory skills assessment
• Muscle strength
• Behaviour and environmental factors surrounding mealtimes

The occupational therapist's intervention focuses on the following:

• Improving oral motor skills
• Sensory processing
• Promoting correct posture
• Selecting adaptive devices and choosing strategies to use them functionally
• Adjusting and adapting the environment to promote independent eating
• Working with parents and caregivers on using different feeding methods or techniques

Physical Therapist

Physical therapy interventions are part of the oral motor therapy (OMT). OMT can improve child's functional independence and the quality of life. Protocols for OMT vary and may include the following:

• Passive range of motion exercises
• Active-assistive range of motion exercises
• The oral motor facilitation technique (OMFT)
• Passive sensory stimulation of the muscles of the face and mouth with different textures and therapeutic devices
• Relaxation techniques for muscles responsible for sucking, swallowing, and chewing using the strain-counterstrain (SCS) technique and the NeuroDevelopmental Treatment-Bobath (NDT-Bobath) method
• Strain-counterstrain technique to relax the tensed muscles including the masseter muscle and the sternocleidomastoid muscle

Feeding and Eating Management Strategies

Goals and Outcomes

General goal: "to improve the quality of life for both the child and family, through interventions that maximise independence in activities of daily living, mobility, and nutrition".

The outcome measures will vary depending on the following:

• type of cerebral palsy: spastic vs nonspastic
• location of motor involvement: diplegia, quadriplegia, etc.
• the child' functional status, including ability to walk or sit, and degree of head and trunk control
