Translation and cross cultural adaptation of the Pediatric Motor Activity Log-Revised scale

"How Well" and "How Often" questions for birth brachial plexus injury: a validity and reliability of the pediatric upper extremity motor activity log-revised

PURPOSE

The pediatric upper extremity motor activity log-revised (PMAL-R) is a structured interview that measures use of the affected arm in daily life in children with unilateral pathologies like hemiparetic cerebral palsy (CP) or birth brachial plexus injury (BBPI). This study investigated validity and test-retest reliability of the PMAL-R in children with BBPI.

MATERIALS AND METHODS

The PMAL-R was administered to parents of 132 children with BBPI between 5 and 9 years for validity, also 98 parents were re-interviewed after 3 weeks to establish test-retest reliability. Its concurrent validity was examined by correlating scores on the PMAL-R How Well (HW) and How Often (HO) scales with Brachial Plexus Outcome Measure (BPOM) and Pediatric Outcomes Data Collection Instrument (PODCI) scores.

RESULTS

PMAL-R scores were strongly correlated with BPOM scores (HW, r = 0.943, p < 0.001; HO, r = 0.897, p < 0.001), also strongly correlated with PODCI (HW, r = 0.799, p < 0.001; HO, r = 0.797, p < 0.001). PMAL-R test-retest reliability (intraclass correlation; HO = 0.997, HW = 0.998) and internal consistency (Cronbach's a; HO = 0.99, HW = 0.99) were high.

CONCLUSIONS

The PMAL-R has good reliability and validity for measuring everyday use of the affected arm with "how often" and "how well" questions in children with BBPI. Implications for rehabilitationThe pediatric upper extremity motor activity log-revised (PMAL-R) is the first tool to assess both "how often" and "how well" the affected arm is used in unimanual activities in children with BBPI.PMAL-R is a real-world measure providing valuable information about "how often" and "how well" the affected arm is used to guide treatment.PMAL-R is valid in both concurrent and discriminative validity in children with BBPI.PMAL-R is reliable in children with BBPI.

Validity and reliability of the Turkish version of the pediatric motor activity log-revised (PMAL-R) for 2-17 year old children with hemiparetic cerebral palsy

PURPOSE

The Pediatric Upper-extremity Motor Activity Log-Revised (PMAL-R) is a structured interview that measures use of the more-affected arm in daily life in children with cerebral palsy (CP). This study investigated the concurrent validity and test-retest reliability of a Turkish version of the PMAL-R.

MATERIALS AND METHODS

The PMAL-R was translated and cross-culturally adapted to Turkish and administered to parents of eighty children with hemiplegic CP between 2-17 years. Its concurrent validity was examined by correlating scores on the PMAL-R How Well and How Often scales with ABILHAND-Kids scores. Fifty parents were re-interviewed after three weeks to establish test-retest reliability.

RESULTS

PMAL-R scores were strongly correlated with ABILHAND-Kids scores (How Well scale, r = 0.78, p < 0.001; How Often scale, r = 0.59, p < 0.001). PMAL-R test-retest reliability (Intraclass correlation; How Often = 0.98, How Well = 0.99) and internal consistency (Cronbach's α; How Often = 0.96, How Well = 0.97) were high.

CONCLUSIONS

This translation of the PMAL-R has good reliability and validity for measuring everyday use of the more-affected arm in Turkish children with hemiparesis due to CP between 2-17 years. Implications for rehabilitationAn instrument that evaluates real-world arm use in Turkish children with CP.Reliability and concurrent validity of the Turkish PMAL-R is established in 2-17-year old with upper-extremity hemiparesis.Systematic replication of the clinimetric properties of the English PMAL-R is demonstrated in a wider age range than previously, 2-17 years vs. 2-8 years.Reliability and concurrent validity of the PMAL-R is shown in both children with right and left hemiparesis.

Intervention bimanual stimulates the abilities in infants with asymmetry

Abstract Introduction: The cerebral palsy and brachial plexus injury may cause asymmetry in the use of the upper limbs (UL). This condition requires early treatment to reduce the impact of the child's life; therefore, several proposed interventions aim to increase their functional independence. The Constraint-Induced Movement Therapy (CIMT) and Hand-Arm Bimanual Intensive Therapy (HABIT) have been widely considered effective interventions to improve hand function. Objective: Investigate the effects of an intervention protocol based on the CIMT and HABIT theoretical foundations in the stimulation of manual function in infants with the UL asymmetry. Methods: Five infants (6-24 months) participated in the study. To evaluate the motor function of infants we used Pediatric Motor Activity Log (PMAL-R) and Manual Function Evaluation (AMIGO), and to assess the caregiver's perception of the participation of the infant in daily tasks, we used the Pediatric Disability Assessment Inventory (PEDI). All evaluations occurred before, immediately after the intervention, and after four months for follow-up recording, and were analyzed descriptively by Jacobson- Truax method. Results: The results between evaluation and reevaluation demonstrated evolution in all aspects studied. In the PEDI self-care session, an average of 38.6 (±8.4) - 44.2 (±7.4); PEDI Mobility: 28.8 (±20.3) - 36.28 (±21.7); PEDI Social Function: 40.1 (±10.2) - 42.3 (±8.9). The PMAL-R quantity and quality results evidence a highly positive clinical significance in all infants. Conclusion: The application of the modified restriction intervention protocol resulted in reliable and clinically significant changes in all cases.
