A registered chiropractor will assess the entire spine, and both sacroiliac joints will be assessed for vertebral subluxation by a registered chiropractor. The clinical indicators that will be used to assess the function of the spine before spinal adjustment intervention include assessing for joint tenderness to palpation manually palpating for a restricted intersegmental range of motion, assessing for palpable asymmetric intervertebral muscle tension, and any abnormal or blocked joint play and end-feel of the joints.

The participants head and/or spine will be moved in ways that include passive and active movements, similar to what is done when assessing the spine by a chiropractor.No spinal adjustment will be performed during any control intervention.

The participants head and/or spine will be moved in ways that include passive and active movements, similar to what is done when assessing the spine by a chiropractor. The sham intervention will also include the participants moving into adjustment setup positions similar to how the chiropractor would typically set up a patient with no joint pre-loading or adjustive thrust

The gross motor function measure is a standard instrument that measures the change in motor function with time in Cerebral palsy subjects. It assesses the number of motor tasks a child can perform.

A scoring key of 0 - does not initiate, 1 - initiates, 2 - partially completes, and 3 - completed, is used. the higher score, the greater is Gross motor function.

TCMS is an extended version of the trunk impairment scale with a total score of 58, which assesses the quality of static and dynamic trunk control.

The maximum value for the total TCMS is 58 points (20 for the category 'static sitting balance', 28 for 'selective movement control', and 10 for 'dynamic reaching'). A higher TCMS score indicates better performance in trunk control.

Melbourne Assessment of Unilateral Upper Limb Function (MUUL) is considered as one of the reliable tools to measure upper limb function. It consists of 16-items to measure the quality of unilateral upper limb function.

Scoring is completed across the 30 score items using a three, four or five-point scale and individually defined scoring criteria. Item scores relating to each element of movement measured are summed within the corresponding sub-scale.

It is a client-centred outcome measure that helps the client to identify occupational performance issues and rates performance and satisfaction pre and post-intervention.

Total scores are calculated by adding together the performance or satisfaction scores for all problems and dividing them by the number of problems. At reassessment, the client scores each problem again for performance and satisfaction.
