Abstract

BACKGROUND:

Hip dislocation in children with cerebral palsy (CP) is a common and severe problem. The dislocation can be avoided, by screening and preventive treatment of children with hips at risk. The aim of this study was to analyse the characteristics of children with CP who develop hip displacement, in order to optimise a hip surveillance programme.

METHODS:

In a total population of children with CP a standardised clinical and radiological follow-up of the hips was carried out as a part of a hip prevention programme. The present study is based on 212 children followed until 9-16 years of age.

RESULTS:

Of the 212 children, 38 (18%) developed displacement with Migration Percentage (MP) >40% and further 19 (9%) MP between 33 and 39%. Mean age at first registration of hip displacement was 4 years, but some hips showed MP > 40% already at two years of age. The passive range of hip motion at the time of first registration of hip displacement did not differ significantly from the findings in hips without displacement. The risk of hip displacement varied according to CP-subtype, from 0% in children with pure ataxia to 79% in children with spastic tetraplegia. The risk of displacement (MP > 40%) was directly related to the level of gross motor function, classified according to the gross motor function classification system, GMFCS, from 0% in children in GMFCS level I to 64% in GMFCS level V.

CONCLUSION:

Hip displacement in CP often occurs already at 2-3 years of age. Range of motion is a poor indicator of hips at risk. Thus early identification and early radiographic examination of children at risk is of great importance. The risk of hip displacement varies according to both CP-subtype and GMFCS. It is sometimes not possible to determine subtype before 4 years of age, and at present several definitions and classification systems are used. GMFCS is valid and reliable from 2 years of age, and it is internationally accepted. We recommend a hip surveillance programme for children with CP with radiographic examinations based on the child‘s age and GMFCS level.

Limb contractures in progressive neuromuscular disease and the role of stretching, orthotics, and surgery

date:1998 Feb;9(1):187-211
author: McDonald CM1.
publication: Phys Med Rehabil Clin N Am.
pubmed_ID: 9894140

 

Abstract

Contractures are exceedingly common impairments in selected progressive NMD conditions, particularly those with excessive fibrosis and fatty infiltration into muscle (i.e., dystrophic myopathies) and more severe NMD conditions, resulting in significant weakness and wheel-chair reliance, such as SMA. Less than antigravity strength produces an inability to achieve full active range of motion. Static positioning of limbs (generally in flexion) and lack of weight bearing results in fixed contractures. This article has reviewed the prevalence and distribution of contractures in specific NMD conditions. Aggressive rehabilitation strategies, including stretching, positioning, splinting, upright weight bearing, and orthopaedic surgical management may help minimize the degree of disability in NMD patients with contractures.

author:Macias-Merlo L1, Bagur-Calafat C, Girabent-Farrés M, Stuberg WA.

publication: Pediatr Phys Ther.
pubmed_ID: 26020594

 

Abstract

PURPOSE:

To investigate the effects of a standing program on the range of motion (ROM) of hip abduction in children with spastic diplegic cerebral palsy.

METHODS:

The participants were 13 children, Gross Motor Functional Classification System level III, who received physical therapy and a daily standing program using a custom-fabricated stander from 12 to 14 months of age to the age of 5 years. Hip abduction ROM was goniometrically assessed at baseline and at 5 years.

RESULTS:

Baseline hip abduction was 42° at baseline and 43° at 5 years.

CONCLUSIONS:

This small difference was not clinically significant, but did demonstrate that it was possible to maintain hip abduction ROM in the spastic adductor muscles of children with cerebral palsy with a daily standing program during the children‘s first 5 years of development.

Abstract

PURPOSE:

Early identification and intervention with conservative measures is important to help manage hip dysplasia in children with a high adductor and iliopsoas tone and delay in weight bearing. The effect of a daily standing program with hip abduction on hip acetabular development in ambulatory children with cerebral palsy was studied.

METHOD:

The participants were 26 children with spastic diplegia cerebral palsy (CP), classified at Level III according to the Gross Motor Function Classification System (GMFCS). Thirteen children stood with hip abduction at least 1 h daily from 12 to 14 months of age to 5 years with an individually fabricated standing frame with hip abduction.

RESULTS:

At the age of 5 years, radiologic results of the study group were compared with a comparison group of 13 children with spastic diplegia CP who had not taken part in a standing program. The migration percentage in all children who stood with abduction remained within stable limits (13-23%) at 5 years of age, in comparison to children who did not stand in abduction (12-47%) (p < 0.01).

CONCLUSIONS:

The results indicate that a daily standing program with hip abduction in the first 5 years may enhance acetabular development in ambulatory children with spastic diplegia CP. Implications for Rehabilitation Abnormal acetabular development is a problem related to mobility problems and spasticity muscles around the hip. The literature suggests that postural management and standing programs could reduce levels of hip subluxation and increase function in children with cerebral palsy. A standing program with hip abduction can be a beneficial to develop more stable hips in children with spastic diplegic GMFCS level III.

Abstract

The purpose of this study was to determine the effects of prolonged standing on gait characteristics in children with spastic cerebral palsy. Six children with spastic cerebral palsy participated in this study with an average age of 6.5 years (SD = 2.5, range = 4.0-9.8 years). A reverse baseline design (A-B-A) was used over a 9-week period. During phase A, the children received their usual physical therapy treatment. During phase B, children received the prolonged standing program three times per week, in addition to their usual physical therapy treatment. During phase A2, children received their usual physical therapy treatment. Gait analysis and clinical assessment of spasticity were performed before and after each phase. Analysis of variance (ANOVA) for repeated measurements was used to test for changes in gait measures across the four measurement sessions. Friedman’s was used to test for changes in muscle tone (Modified Ashworth Scale) across the four measurement sessions. Stride length (p <.001), gait speed (p <.001), stride time (p <.001), stance phase time (p <.001), double support time (p <.003), muscle tone (p <.02), and peak dorsiflexion angle during midstance (p <.004) improved significantly following the intervention phase. The results of this study demonstrate that the gait pattern of children with cerebral palsy classified as level II or III on the Gross Motor Functional Classification System (GMFCS) improved by a prolonged standing program. However, these improvements were not maintained at 3 weeks. Further research is necessary with larger sample sizes to replicate these findings and determine specific “dosing” for standing programs to create long-lasting functional effects on gait.

Effect of weight-bearing in abduction and extension on hip stability in children with cerebral palsy.

date: 2011 Summer;23(2):150-7
author: Martinsson C1, Himmelmann K.
publication:Pediatr Phys Ther.
pubmed_ID: 21552077

 

Abstract

PURPOSE:

: To study the effect of 1 year of daily, straddled weight-bearing on hip migration percentage (MP) and muscle length in children with cerebral palsy who were nonambulatory.

METHODS:

: Participants stood upright in maximum tolerated hip abduction and hip and knee extension ½ to 1½ hours per day for 1 year. Controls, matched for age, motor ability, and surgery, were derived from a national cerebral palsy follow-up program.

RESULTS:

: Participants using straddled weight-bearing after surgery had the largest decrease in MP (n = 3, 20 controls; P = .026). Children using straddled weight-bearing at least 1 hour per day for prevention also improved (n = 8, 63 controls; P = .029). Hip and knee contractures were found only in controls.

CONCLUSION:

: Straddled weight-bearing, 1 hour per day, may reduce the MP after adductor-iliopsoas-tenotomies or prevent an MP increase and preserve muscle length in children with cerebral palsy who did not need surgery. Larger studies are needed to confirm the results.

Abstract

The objective of this study was to determine whether static weight-bearing in a standing frame affected hamstring length and ease of activities of daily living (ADLs) in nonambulant children with cerebral palsy (CP). A convenient sample of nonambulant children with CP was recruited for this one-group quasi-experimental study. Participants stood in a standing frame for 1 h, 5 days per week, for 6 weeks, followed by 6 weeks of not using a standing frame; each phase was repeated. Popliteal angle measurements were made at baseline and weekly throughout the study period. Carers provided written feedback regarding ease of ADLs at the end of each standing and nonstanding phase. Five children were recruited (age range 6-9 years, mean age 7 years 2 months, SD 1 year 4 months). High compliance with the standing regime was achieved (85% of intended sessions completed). Repeated-measures analysis of variance and t-tests showed hamstrings significantly lengthened during standing phases (mean improvement 18.1 degrees , SD 5.5, P<0.01 for first standing phase; mean improvement 12.1 degrees , SD 7.7, P=0.03 for second standing phase). A trend for hamstrings to shorten during nonstanding phases was observed (mean change -14.0 degrees , SD 4.2, P=0.02 for first nonstanding phase; mean change -7.3 degrees , SD 6.5, P=0.20 for second nonstanding phase). Feedback from carers suggested that transfers and ADLs became slightly easier after phases of standing frame use. Preliminary evidence that 6 weeks of standing frame use leads to significant improvements in hamstring length in nonambulant children with CP, and may increase ease of performance of ADLs was found.

Abstract

PURPOSE:

To demonstrate the feasibility of an innovative program of physical activity using a standing–support device targeted towards adult residents of a nursing home who are unable to transfer or stand independently.

METHOD:

Intervention study.

PARTICIPANTS:

Thirteen residents, age 82 +/- 11 years, at the Beit Bayer Nursing Home, Jerusalem, Israel, who were unable to transfer or stand independently.

INTERVENTION:

Eight-week observational period followed by 12-week physical activity performed while standing in a Standing–Support Device.

MEASUREMENTS:

Manual Muscle Testing, joint range of motion, forward and lateral reach, time to stand independently, distance walked with a walker, Functional Independence Measure.

RESULTS:

Compared to the observational period, significant post-intervention improvements were noted particularly in lower extremity muscle strength. Improvements in the Functional Independence Measure were noted in sphincter control, locomotion, mobility, motor score, and total score. Over 60% of those previously requiring assistance in standing became able to stand for an average of 1 min unassisted and walk an average of 14 m with a walker.

CONCLUSION:

A pilot program of physical activity using a Standing–Support Device is feasible in selected stance-disabled older adult nursing home residents. Participants showed evidence of muscle strength and functional improvement. Future studies of the device with a concurrent examination of healthcare costs, functional improvement, and staff burden, are recommended.

Cardiovascular and haemodynamic responses to tilting and to standing in tetraplegic patients: a review

date:1984 Apr;22(2):99-109
author: Figoni SF.
publication: Paraplegia.
pubmed_ID:6379566

Abstract

This paper has reviewed the acute and long-term responses to changes in vertical posture in normal and tetraplegic subjects. It has discussed physiological mechanisms causing orthostatic hypotension in acute cervical spinal cord injured patients, and subsequent factors contributing to its amelioration over time. The long-term adaptive mechanisms are still controversial, probably involving multiple neurological, endocrine, renal, cardiovascular and haemodynamic factors. These factors include inhibition of vagal tone, plasma catecholamine levels, sensitivity of vascular beds to catecholamines, stretch reflexes in blood vessels, spinal BP reflexes, renin-angiotensin system, aldosterone and plasma volume changes. Individual differences may also interact with these various mechanisms, further complicating the issues. Although the fact that most tetraplegics do improve their orthostatic tolerance over time with repeated tilting is manifest, the precise mechanisms allowing this improvement are not. Research is needed to clarify these adaptive mechanisms, as well as to investigate the physiological effects of long-term therapeutic standing in devices such as standing frames.

Abstract

BACKGROUND:

Systems of functional electrical stimulation (FES) have been demonstrated to enable some persons with paraplegia to stand and ambulate limited distances. However, the energy costs and acute physiologic responses associated with FES standing activities have not been well investigated.

OBJECTIVE:

To compare the physiologic responses of persons with paraplegia to active FES-assisted standing (AS) and frame-supported passive standing (PS).

METHODS:

Fifteen persons with paraplegia (T6-T11) previously habituated to FES ambulation, completed physiologic testing of PS and AS. The AS assessments were performed using a commercial FES system (Parastep-1; Altimed, Fresno, Calif); the PS tests used a commercial standing frame (Easy Stand 5000; Altimed, Fresno, Calif). Participants also performed a peak arm-cranking exercise (ACE) test using a progressive graded protocol in 3-minute stages and 10-watt power output increments to exhaustion. During all assessments, metabolic activity and heart rate (HR) were measured via open-circuit spirometry and 12-lead electrocardiography, respectively. Absolute physiologic responses to PS and AS were averaged over 1-minute periods at 5-minute intervals (5, 10, 15, 20, 25, and 30 minutes) and adjusted relative to peak values displayed during ACE to determine percentage of peak (%pk) values. Absolute and relative responses were compared between test conditions (AS and PS) and across time using two-way analysis of variance.

RESULTS:

The AS produced significantly greater values of VO2 (43%pk) than did PS (20%pk). The mean HR responses to PS (100-102 beats per minute [bpm] throughout) were significantly lower than during AS, which ranged from 108 bpm at 5 minutes to 132 bpm at test termination.

CONCLUSION:

Standing with FES requires significantly more energy than does AS and may provide a cardiorespiratory stress sufficient to meet minimal requirements for exercise conditioning.
