* Study will be started after obtaining ethical clearance and registration with Clinical trials registry of India
* Hindi translation of SPCQ-2(Sensory profile caregiver questionnaire 2) by subject expert by forward and independent backward translation .
* Consecutive children of either sexes between 3-12 years with a clinical diagnosis of spastic cerebral palsy will be examined by the investigator and those having sensory abnormalities as screened by Sensory profile caregiver questionnaire 2 will be included in the study group.
* Those children who screen positive for sensory abnormalities fulfilling the inclusion criteria would be enrolled in the study after obtaining informed consent from the parents or guardian.
* Once enrolled children would be randomized into 2 groups , using a computer generated random number sequence, an interventional group receiving sensory integration therapy along with standard therapy and a group receiving standard therapy alone.
* Concealment of the random allocation would be ensured by placing the allocation sequence in serially numbered, tamper proof, opaque and sealed envelopes(by a person other than primary investigator to ensure blinding and further observation bias)
* Post - enrollment - Baseline clinical and demographic data will be recorded along with associated co morbidities (maladaptive behavior, sensory deficits and motor problems).
* Pre-intervention a baseline motor skill will be obtained using Gross Motor Function Measure -88 and behavioral assessment would be done using Child Behaviour Checklist within 7 days of starting therapy in both arms (by pediatric neurologist ,child psychologist respectively and who is unaware of the randomization and allocation to both arms to prevent observer bias).
* Pre-intervention investigator would also interact with the parents or the primary care giver and record parent's assessment of severity of sensory abnormalities in 5 main domains - auditory , visual, tactile, proprioceptive and vestibular senses on a 10 item Likert scale and also assess Quality of life using Pediatric Quality of life using Pediatric Quality of life scale
* All children would be followed at set intervals from initiation of therapy as noted below ;
* Weekly for 2 weeks then fortnightly for next 10 weeks to ensure proper technique and compliance.
* At 3 months the blinded outcome assessor and child psychologist will re evaluate the enrolled candidate to determine for any change by using Gross Motor Function Measure -88 , 10 item parent rated Likert scale, Child Behaviour Checklist and Pediatric Quality of life as compared to baseline within 7 days of completion of therapy in both arms
The first visit would be primarily aimed at reinforcing the techniques of therapy and clarifying parent's doubts. At 3 month visit child would be evaluated and re-assessed using the scores- 10 item Likert scale rated by parents, Gross Motor Function Measure -88 and Pediatric Quality of life scale . Parents would be encouraged to bring one random home video of child doing activity-based therapy at 2 weeks wherever feasible . The video would be used for ,
* Assessing the correct technique
* Suggesting modifications in the activity schedule if required
* Helps in ensuring adherence to technique
Compliance would be ensured by the
* Activity log
* Telephonic re-enforcement from the primary investigator weekly
