Long-term follow-up of thalidomide embryopathy: malformations and development of osteoarthritis in the lower extremities and evaluation of upper extremity function.

ABSTRACT:

Background

Between 1959 and 1962, several children with multiple malformations were born after maternal intake of thalidomide during pregnancy, known as thalidomide embryopathy (TE).

Objectives

The aim of this study was to evaluate the malformations, their long-term effect on the function of the extremities and the development of degenerative osteoarthritis (OA) in the lower extremities.

Methods

All living persons with TE in Sweden were invited to participate in the study. Thirty-one patients were examined clinically as a part of a multi-disciplinary follow-up programme. Evaluation of upper and lower limb function was performed by validated questionnaires [Disabilities of the Arm, Shoulder and Hand (DASH) and Rheumatoid and Arthritis Outcome Score (RAOS), respectively] and radiographic appearance of lower limbs by the use of spiral computed tomography.

Results

Five individuals had severe malformations of the lower limbs and proximal femoral focal deficiency (PFFD), with significantly reduced function as found on the RAOS values. Twenty-seven patients had two fully functional arms and hands, despite the fact that 8% of shoulders, 26% of elbows/forearms and 70% of hands were malformed. Loss of gripping function did not significantly affect the upper extremity function, as measured by the DASH score. Ten patients without major deformities had OA in the hips and 15 in the knees, mostly mild and with no effect on the RAOS value.

Conclusion

A wide variety of malformations in the upper and lower limbs was found in the study group. Degenerative changes were found in the hips and the knees but were mostly mild and without major clinical significance. Despite upper limb anomalies that affected the fine motor skills, upper extremity function was not significantly reduced for most individuals. Individuals with PFFD along with major deformities of upper limbs had a reduced function of upper as well as lower limbs.

Project description:Hand-Arm Bimanual Intensive Therapy (HABIT) promotes hand function using intensive practice of bimanual functional and play tasks. This intervention has shown to be efficacious to improve upper-extremity (UE) function in children with unilateral spastic cerebral palsy (USCP). In addition to UE function deficits, lower-extremity (LE) function and UE-LE coordination are also impaired in children with USCP. Recently, a new intervention has been introduced in which the LE is simultaneously engaged during HABIT (Hand-Arm Bimanual Intensive Therapy Including Lower Extremities; HABIT-ILE). Positive effects of this therapy have been demonstrated for both the UE and LE function in children with USCP. However, it is unknown whether the addition of this constant LE component during a bimanual intensive therapy attenuates UE improvements observed in children with USCP. This retrospective study, based on multiple randomized protocols, aims to compare the UE function improvements in children with USCP after HABIT or HABIT-ILE. This study included 86 children with USCP who received 90 h of either HABIT (n = 42) or HABIT-ILE (n = 44) as participants in previous studies. Children were assessed before, after, and 4-6 months after intervention. Primary outcomes were the ABILHAND-Kids and the Assisting Hand Assessment. Secondary measures included the Jebsen-Taylor Test of Hand Function, the Pediatric Evaluation of Disability Inventory [(PEDI); only the self-care functional ability domain] and the Canadian Occupational Performance Measure (COPM). Data analysis was performed using two-way repeated-measures analysis of variance with repeated measures on test sessions. Both groups showed similar, significant improvements for all tests (test session effect p < 0.001; group × test session interaction p > 0.05) except the PEDI and COPM. Larger improvements on these tests were found for the HABIT-ILE group (test session effect p < 0.001; group × test session interaction p < 0.05). These larger improvements may be explained by the constant simultaneous UE-LE engagement observed during the HABIT-ILE intervention since many daily living activities included in the PEDI and the COPM goals involve the LE and, more specifically, UE-LE coordination. We conclude that UE improvements in children with USCP are not attenuated by simultaneous UE-LE engagement during intensive intervention. In addition, systematic LE engagement during bimanual intensive intervention (HABIT-ILE) leads to larger functional improvements in activities of daily living involving the LE.
