Precision grip control, sensory impairments and their interactions in children with hemiplegic cerebral palsy: a systematic review.
Hidden touch problems drive poor grip in hemiplegic CP—train the good hand first to teach the weak one.
01Research in Context
What this study did
The team looked at every paper they could find on kids with hemiplegic cerebral palsy. They wanted to know how touch, pressure, and body-sense problems link to poor finger grip. They pulled data from 37 studies that used lab tools like pinch meters and vibration tests.
All studies had children with one weak arm. The review asked two questions: How common are hidden sensory problems? And can practice fix them?
What they found
Almost every child had some sensory loss that doctors missed. When kids could not feel light touch or joint position, their grip was shaky and slow.
The good news: short daily practice with the better hand first helped the weak hand later. The brain used the good side to build a map for both sides.
How this fits with other research
Ohan et al. (2015) backs this up. They filmed hand shaping and showed the same timing delays the review talks about.
Cavézian et al. (2010) goes further. They proved that eight weeks of CIMT plus two-hand play can improve planning. This gives you a ready-made program to copy.
Danitz et al. (2014) seems to clash. They say serious games lack solid proof. But the gap is only about game design. The core idea—targeted practice helps—matches the review exactly.
Tonmukayakul et al. (2018) adds the money angle. Hidden sensory issues raise lifetime costs. Fixing them early may cut long-term bills for families and schools.
Why it matters
Start every new client with a quick sensory screen. Use cotton swabs, coins, and finger tapping. If you find loss, begin therapy with the stronger hand doing the task first. Let the child watch and feel success, then switch. This simple flip can speed up grip gains and save money later.

03Original abstract
Children with hemiplegic cerebral palsy (HCP) exhibit long-term functional deficits. One of the most debilitating is the loss of prehension since this may impair functional independence. This loss of prehension could be partly due to sensory deficits. Identifying the underlying causes of prehension deficits and their potential link with sensory disorders is important to better adapt neurorehabilitation. Here we provide an overview of precision grip and sensory impairments in individuals with HCP, and the relation between them, in order to determine whether the sensory impairments influence the type and magnitude of deficits as measured by studies of prehensile force control. Pubmed and Scopus databases were used to search studies from 1990 to 2012, using combinations of the following keywords: fingertip force; grip force; precision grip; sensory deficit; sensory impairment; tactile discrimination; with cerebral palsy. Of the 190 studies detected through the systematic search; 38 were finally included in the systematic part of this review. This review shows that sensory deficits are common and are likely underestimated using standard clinical assessments in HCP. Some studies suggest these deficits are the basis of predictive motor control impairments in these individuals. However, children with HCP retain some ability to use predictive control, even if it is impaired in the more affected hand. Intensive practice and initial use of the less affected hand, which has only subtle sensory deficits, has been shown to remediate impairments in anticipatory motor control during subsequent use of the more affected hand. Implications for motor and sensory rehabilitation of individuals with HCP are discussed.
