“…18,19 Mohanty et al also supports some of the findings of the present study which revealed that genu recurvatum was controlled with improved gait parameters and energy expenditure by a solid SKAFO in which ankle was fixed in neutral position. 20 In a systematic review, Figueiredo et al found that stride and step length and gait velocity did not show any single trend with the use of different designs of AFO which was contradictory to the present findings . 21 The result of the present study also showed that velocity and cadence were markedly reduced and almost found same in every case after using the orthosis.…”

“…Mohanty et al does not support the present findings which showed that there was increased in velocity and cadence with the use of solid SKAFO in which ankle was fixed in neutral position. 20 Figueiredo et al also agreed with the results of present findings which showed that cadence was decreased with different AFO designs when compared with no AFO . 21 It is difficult to generalize the results due to less sample size.…”

Background: In cerebral palsy, importance must be given on effective and efficient walking. 30 subjects; 16 males and 14 females (mean age 6.5 year) of spastic cerebral palsy with knee hyperextension and ankle equines were included in this study and were fitted with bilateral moldedhinged SKAFO with pair of shoes.Methods: Observational gait analysis by video recording was performed and gait parameters by 10 m walk test and knee angle at mid stance using goniometer in standing position were recorded in bracing and non-bracing conditions.Results: The orthosis controlled knee hyperextension by not restricting normal flexion and extension moment with smooth transition of ankle motion. There was significant improvement in step length; stride length as well as knee angle at midstance (with orthosis) but velocity and cadence were reduced as compared to bare foot walking.Conclusions: A stable, natural and controlled knee hyperextension gait pattern was found.

Recurvatum of the Knee in Cerebral Palsy: A Review

Recurvatum is defined as hyperextension of the knee in the stance phase of gait. Recurvatum knee is a naturally occurring common gait deviation in those with cerebral palsy, along with crouch knee, jump knee, and stiff knee gaits. Early and late recurvatum occur in the first and second halves of stance. Early recurvatum is associated with dynamic calf contraction that raises the heel and pushes the knee into hyperextension as the forefoot contacts the floor. Late recurvatum occurs after the foot is already flat on the floor. As the body weight comes forward over the foot, the tibia stops its forward motion too early as the ankle comes to its range-of-motion limit. The advancing body then moves forward over a hyperextending knee. Surgical hamstring lengthening can have recurvatum as a side effect. There are several strategies to decrease this risk. Medial hamstring lengthening may be safer than combined medial and lateral lengthening. The concept here is that less lengthening or less aggressive lengthening means less recurvatum risk. However, combined medial and lateral lengthening can be reasonably safe from the risk of causing recurvatum if the knee is showing enough preoperative flexion in stance to warrant the increased surgery. More flexion in stance relates to less risk, while less flexion in stance relates to more risk. Knee flexion in stance can be measured. This is done by measuring knee flexion at initial contact and knee flexion in stance in a gait lab or with stop-action video. If there is minimal knee flexion in stance, hamstring lengthening might not be advisable, even if the hamstrings are tight on popliteal angle testing. There are other factors that contribute to recurvatum risk, such as knee hyperextension on static exam, equinus contracture, and jump knee gait. For treatment of recurvatum, the mainstay is the use of ankle foot orthoses set in dorsiflexion. Surgical equinus correction in those with early stance recurvatum can be effective but it is not likely to be effective in those with late stance recurvatum.
