- Brief Summary
Management of excessive crying in children with cerebral palsy and communication deficits \[ECCCPCD\] was guided by the associated clinical findings and investigations.
- Detailed Description
Pain treatments are frequently hit or miss, trial \& error, or because of the fear of litigations, not offered at all, particularly in cerebral palsy. Pain is an under-suspected and under-diagnosed cause of ECCCPCD. It was hypothesized that pain/discomfort was responsible for ECCCPCD, and a vicious cycle of pain-spasm-pain aggravated the pain/discomfort. So, the response of ECCCPCD to treatment guided by clinical findings \& investigations was studied.
There was an initial placebo run-in period. This study was a prospective, single-center, interventional, with initial placebo-control, double-blind for initial 110 days, open-label for the next 290 days, fixed-sequence, two treatment, two-period, crossover clinical trial. The placebo run-in period (15 days) was followed by the placebo period (15 days). After a washout period (10 days), drug treatment (360 days) was started depending on the clinical findings and investigations. The drugs used either singly or in various combinations were GABA-B agonists, muscarinic acetylcholine receptor antagonists, benzodiazepines, inhibitors of the vesicular monoamine transporter, antiepileptics, and tricyclic antidepressants. The outcome measure was total, and unexplained mean cry durations in hours per day. The cry duration was measured for one 10-day period while on placebo \[days P6-P15\], and four 10-day periods while on treatment \[T61-70, T241-250, T311-320, and T351-360\]. Total and unexplained mean cry durations in hours per day were calculated from 10-day measurements of cry durations. From the 251st day of therapy, the dose was reduced by 5% every week until \[ECCCPCD\] started to increase. This reduction of the dose was made to confirm the efficacy of drugs and to check if the dosage requirement has reduced after 250 days of treatment. This dose was maintained until the next measurement between T311 and T320. Then the dosages were adjusted as necessary. The caregivers were allowed to volunteer any additional observations of interest. Drug adverse effects were recorded.
Epidemiological data, GMFCS levels, and MAS scores were noted at the time of enrollment. Summary statistics were tabulated and plotted. Paired t-tests and Wilcoxon tests were done to study the statistical significance.

Group Intervention Description Placebo-Sequence 1 Placebo The placebo contained fructose powder in packets identical to the medicines. Drug-Sequence 2 Baclofen, Diazepam, Clonazepam, Trihexyphenidyl, Tetrabenazine, Gabapentin, Topiramate, Lamotrigine, Amitriptyline. GABA-B agonists, muscarinic acetylcholine receptor antagonists, inhibitors of the vesicular monoamine transporter, benzodiazepines, antiepileptics, and tricyclic antidepressants were used.
- Primary Outcome Measures
Name Time Method Epidemiologic data (Age and sex). 400 days. Epidemiologic data (age rounded up in years, sex-number of males, females, and transgender, if any).
The Modified Ashworth Scale (MAS) scores 400 days The Modified Ashworth Scale (MAS) scores from 0 to 4 were used. A higher score means a worse condition.
The Gross Motor Function Classification System (GMFCS) levels 400 days The gross motor function of children with cerebral palsy was categorized into 5 different levels using the Gross Motor Function Classification System tool. A higher score means a worse condition.
Measurement of both Total and Unexplained cry durations 400 days Caregivers measured both Total and Unexplained cry durations with a digital watch or a mobile phone in hours: minutes: seconds over five ten-day periods. MM1 while on placebo days 6-15 \[P6-P15\], and four measurements MM2 to MM5 while on treatment days 61-70 \[T61-70\], 241-250 \[T241-250\], 311-320 \[T311-320\], and 351-360 \[T351-360\].
Statistician calculated means of cry duration in hours per day.
- Secondary Outcome Measures
Name Time Method Any other changes in the clinical profile observed during the study period and reported by the caregivers. 400 days Any other changes in the clinical profile (frequency changes) observed during the study period were reported by the caregivers. The number and percentages of children with the change were calculated.
