A physiotherapist can develop patient specific training programs to optimize postural control, in order to increase balance and safety. To protect against postural asymmetries the use of supportive and protective devices may be necessary. Physical therapists might use neuromuscular/sensory stimulation techniques such as quick stretch, resistance, joint approximation, and tapping to increase tone by facilitating or enhancing muscle contraction in patients with hypotonia. For patients who demonstrate muscle weakness in addition to hypotonia strengthening exercises that do not overload the muscles are indicated. Electrical Muscle Stimulation, also known as Neuromuscular Electrical Stimulation (NMES) can also be used to “activate hypotonic muscles, improve strength, and generate movement in paralyzed limbs while preventing disuse atrophy (p.498).”  When using NMES it is important to have the patient focus on attempting to contract the muscle(s) being stimulated. Without such concentration on movement attempts, carryover to volitional movement is not feasible. NMES should ideally be combined with functional training activities to improve outcomes. Occupational therapy can assist the patient with increasing independence with daily tasks through improvement of motor skills, strength, and functional endurance. Speech-language therapy can help with any breathing, speech, and/or swallowing difficulties the patient may be having. Therapy for infants and young children may also include sensory stimulation programs. A physical therapist may recommend an ankle/foot orthosis to help the patient compensate for weak lower leg muscles. Toddlers and children with speech difficulties may benefit greatly by using sign language.
"True muscle tone is the inherent ability of the muscle to respond to a stretch. For example, quickly straightening the flexed elbow of an unsuspecting child with normal tone, will cause their biceps to contract in response (automatic protection against possible injury). When the perceived danger has passed, (which the brain figures out once the stimulus is removed), the muscle relaxes and returns to its normal resting state. ""...The child with low tone has muscles that are slow to initiate a muscle contraction, contract very slowly in response to a stimulus, and cannot maintain a contraction for as long as his normal peers. Because these low-toned muscles do not fully contract before they again relax (muscle accommodates to the stimulus and so shuts down again), they remain loose and very stretchy, never realizing their full potential of maintaining a muscle contraction over time. " Cause
The most common cause of central hypotonia in newborns is hypoxic ischemic encephalopathy. Brain malformations and inborn errors of metabolism account for 13% and 3% respectively. Causes that affects the central nervous systems are: chromosomal disorders,  inborn errors of metabolism, cerebral dysgenesis, and trauma to the brain and spinal cord. Metabolic causes includes: glycogen storage disease type II, pyruvate dehydrogenase deficiency, mitochondrial disease, Zellweger syndrome, Smith–Lemli–Opitz syndrome, and congenital disorder of glycosylation. Metabolic disorders in infants are usually presented with various other features such as dysmorphic feature, seizures, encephalopathy, biochemistry profile apart from hypotonia.Some conditions known to cause hypotonia include:
Congenital – i.e.
