The reliability and validity of the weight-bearing lunge test in a Congenital Talipes Equinovarus population (CTEV).

ABSTRACT:

Question

What is the intra and inter-rater reliability and concurrent validity of the weight-bearing lunge test within a Congenital Talipes Equinovarus population?

Design

Test retest design for reliability and validity. The measure was taken, following preconditioning of the participants, using distance from wall, angle at distal posterior tibia using a digital inclinometer and the iPhone level function, twice by each rater. The raters included a clinician, clinician in training and a parent/carer.

Outcome measures

Weight bearing lunge test as a measure of ankle dorsiflexion.

Results

Twelve children aged 5-10 years were eligible to participate and consented, along with their parents. Intra-reliability of distance measures for all raters were good to excellent (ICC clinician 0.95, ICC training clinician 0.98 and ICC parent 0.89). Intra-rater reliability of the iPhone for all raters was good (ICCs > 0.751) and good to excellent for the inclinometer (ICC clinician 0.87, ICC training clinician 0.90). Concurrent validity between the clinician's and parents distance measure was also high with ICC of 0.899. Inter-rater reliability was excellent for distance measure (ICC = 0.948), good for the inclinometer (ICC = 0.801) and moderate for the iPhone (ICC = 0.68). Standard error of measurement ranged from 0.70-2.05, whilst the minimal detectable change ranged from 1.90-5.70.

Conclusion

The use of the WBLT within this CTEV population has demonstrated good to excellent reliability and validity amongst clinicians, clinicians in training and parents/carers, supporting its use as an assessment measure of dorsiflexion range of motion. There is support for parents/carers to use the WBLT at home as a monitoring assessment measure which may assist with early detection of a relapse.

Project description:BACKGROUND:Treatment of idiopathic congenital talipes equinovarus (CTEV) is challenging for pediatric orthopedic surgeons. The Ponseti method is an effective protocol for treatment due to its technique of manipulation, casting, and limited surgery. Plaster casting is an essential component of the Ponseti method. In this report, we describe a new brace that was developed for use in the treatment of clubfoot in newborns instead of a plaster cast. METHODS:This retrospective study was performed in two orthopedic medical centers. Between January 2011 and October 2013, 89 newborns with CTEV (131?ft) underwent corrective treatment using fixation braces in the experiment group (E-group) in our hospital, and 107 newborns with CTEV (141?ft) underwent plaster casting in the control group (C-group) in another medical center. All patients were treated according to the Ponseti method after the application of the inclusion and exclusion criteria. Plaster casts were applied to patients in the C-group. The patients in the E-group received the custom-made polyaxial fixation braces instead of plaster casts. Prospective follow-up was performed for a mean duration of 36?months. The efficacy of the treatment was assessed using Pirani's scoring system. Chi-squared and independent t tests were used for statistical analyses. RESULTS:In the E-group, 85 patients (125?ft) achieved good appearance within 3?months of treatment initiation (average, 1.7?months). Four patients (6?ft) required percutaneous Achilles tenotomy. Seven patients developed sores during treatment because of improper brace application, but all sores healed without scarring with timely treatment. In the C-group, 96 patients (123?ft) achieved good appearance within 3?months of treatment initiation (average, 1.6?months). Eleven patients (18?ft) required percutaneous Achilles tenotomy. Twenty-one feet developed sores during treatment because of plaster cast pressure on the dorsum of the feet. Sixteen sores healed without scarring with timely treatment, and 5?ft had obvious scars. The overall mean Pirani scores 1 year after treatment were 0.26?±?0.06 in the E-group and 0.25?±?0.03 in the C-group, and the Pirani scores 3 years after treatment were 0.23?±?0.05 in the E-group and 0.22?±?0.03 in the C-group. There were significant differences in the percutaneous Achilles tenotomy and skin sores but no significant difference in the Pirani scores between these two groups. CONCLUSIONS:Our results showed that the new polyaxial fixation brace used in this study was an effective tool for the corrective treatment of CTEV in newborns. We propose the use of this brace as an alternative treatment for newborns.

Project description:BackgroundIdiopathic congenital talipes equinovarus (CTEV) is the commonest form of clubfoot. Its exact cause is unknown, although it is related to limb development. The aim of this study was to quantify the anatomy of the muscle, subcutaneous fat, tibia, fibula and arteries in the lower legs of teenagers and young adults with CTEV using 3D magnetic resonance imaging (MRI), and thus to investigate the anatomical differences between CTEV participants and controls.Methodology/principal findingsThe lower legs of six CTEV (2 bilateral, 4 unilateral) and five control young adults (age 12-28) were imaged using a 3T MRI Philips scanner. 5 of the CTEV participants had undergone soft-tissue and capsular release surgery. 3D T1-weighted and 3D magnetic resonance angiography (MRA) images were acquired. Segmentation software was used for volumetric, anatomical and image analysis. Kolmogorov-Smirnov tests were performed. The volumes of the lower affected leg, muscle, tibia and fibula in unilateral CTEV participants were consistently smaller compared to their contralateral unaffected leg, this was most pronounced in muscle. The proportion of muscle in affected CTEV legs was significantly reduced compared with control and unaffected CTEV legs, whilst proportion of muscular fat increased. No spatial abnormalities in the location or branching of arteries were detected, but hypoplastic anomalies were observed.Conclusions/significanceCombining 3D MRI and MRA is effective for quantitatively characterizing CTEV anatomy. Reduction in leg muscle volume appears to be a sensitive marker. Since 5/6 CTEV cases had soft-tissue surgery, further work is required to confirm that the treatment did not affect the MRI features observed. We propose that the proportion of muscle and intra-muscular fat within the lower leg could provide a valuable addition to current clinical CTEV classification. These measures could be useful for clinical care and guiding treatment pathways, as well as treatment research and clinical audit.
