Rehabilitation following hip fracture surgery: a comparative study of females and males

Purpose: To compare patient, fracture and rehabilitation variables between male and female patients during the rehabilitation period immediately following surgical repair of hip fracture (HF).

Methods: A prospective cohort study was conducted in a rehabilitation geriatric ward in a tertiary university hospital in southern Israel. The study group consisted of 808 elderly patients, 65 years of age or older, selected for hospitalized rehabilitation following surgery for HF. The measurements included functional studies by the Functional Independence Measure (FIM™) scale, mental status by Folstein Minimental Test and Clock Drawing Test, Geriatric Depression Screening Scale (GDS), demographic and social parameters, laboratory tests, length of rehabilitation, complications and mortality during rehabilitation.

Results: Six hundred and fourteen patients (76%) were women and 194 (24%) were men. The mean age ( ± SD) of the women was 78.4 ± 7.1 years and of the men was 77.8 ± 7.5 (NS). There were no significant differences between women and men in terms of the anatomic site of the fracture or the type of surgery, the complication rate or mortality during rehabilitation, the length of time needed for rehabilitation, the framework to which the patient was discharged, FIM values before the HF, on admission and at the end of rehabilitation, or the difference between FIM scores at these last two points in time.

Conclusions: In selected elderly patients with HF gender does not affect variables associated with hip fracture, the rehabilitation process immediately following the fracture, or the results of rehabilitation.     

The work of rehabilitation

Purpose. To describe three years of activity of a rehabilitation unit and to make comparisons between clients who receive different levels of active rehabilitation.

Method. A retrospective study set in an inpatient rehabilitation facility located in Dunedin, New Zealand, examining 874 inpatient admissions over three financial years (2000 - 2002). Outcome measures include Functional Independence Scores (FIM) at admission and discharge, length of stay, weekly gains in FIM scores, and changes in FIM sub-scores.

Results. Assessment and rehabilitation patients made significant FIM gains in comparison to assessment only and social relief (respite care) patients. Assessment and rehabilitation patients showed greater gains in the Physical dimensions of the FIM in comparison to the Cognitive although this is probably a function of different scaling. Floor and ceiling effects were not present in the FIM.

Conclusions. The interdisciplinary rehabilitation program brings about real functional and cognitive gains in a range of patients as measured with the FIM. This adds to the considerable body of research which documents FIM gains and further provides evidence that physical and cognitive gains differ.     

Work-related hand injuries: case analyses in a Brazilian rehabilitation service

Purpose. Professionals who work with rehabilitation of the hand usually assess performance components as their main outcome measures. Intervention is aimed at normalization of deficits of these components, with the expectation that the integrity of the structures and functions of the body will revert to improvements in the client's functional performance. The objectives of this study were to describe changes in patients who received rehabilitation in a Brazilian public hospital after having suffered hand injuries due to workplace accidents, and to examine the relations between performance components and levels of functioning.

Methods. Observational cross-sectional study was used. A convenience sample was selected, including 42 patients assessed at service admission and at discharge. Assessed characteristics included grip strength, wrist and finger range of movement (ROM), sensitivity, and self-perceptions of functional performance (COPM). Statistical procedures included correlations between performance components and COPM scores and differences on selected variables at admission and discharge.

Results. Significant improvements in all assessed functional components. COPM values increased more than 100% after intervention (effect size d = 1.996 for performance and d = 1.553 for satisfaction) demonstrating improvements in both domains. Low correlations between grip strength and COPM scores were found only at admission (r = 0.314; p = 0.045). When the relationship between gains in strength and COPM scores at discharge were examined, significant correlations were found with the performance (r = 0.324; p = 0.039) and satisfaction (r = 0.0326; p = 0.038) subscales.

Conclusions. Results of this study provide evidence for functional gains in clients treated in a rehabilitation service and supply information about the relation between specific components and functional performance.     

Prophylaxis of venous thromboembolism during early inpatient rehabilitation after acquired brain injury: how guidelines change management

Purpose. To establish guidelines for prophylaxis of venous thromboembolism (VTE) in younger adults undergoing early inpatient rehabilitation following acquired brain injury (ABI).

Method. A two-phase (phase 1: retrospective; phase 2: prospective) observational study was carried out involving patients admitted to an inpatient neurological rehabilitation unit during a 40-month period. In phase 1, VTE prophylaxis was prescribed on an ad hoc basis. In phase 2, prophylaxis was considered in accordance with guidelines agreed locally. The prescribing behaviour in each phase of the study was compared using a VTE risk stratification tool based on expert opinion and a review of the literature.

Results. Data were obtained on 94 patients in phase 1 and 23 patients in phase 2. During phase 1, the prophylactic prescribing behaviour of the referring hospitals and our unit after admission were similar ( p = 0.13). In phase 2, our prescribing behaviour had changed compared with that of the referring hospitals, with a significant increase in the proportion of patients on appropriate treatment ( p = 0.01) and a decrease in the numbers under-treated ( p = 0.002). We were also significantly less likely to under-treat ( p = 0.005) and more likely to over-treat ( p = 0.004) after admission during phase 2 compared with phase 1, whilst practice was variable in patients at moderate risk.

Conclusions. Guidelines modify behaviour. They must stratify risk, particularly to avoid inconsistencies in the management of patients at moderate risk. There is a need to establish national guidelines for VTE prophylaxis during early inpatient rehabilitation after ABI; these guidelines should include a risk stratification tool.     

Masculine role variables and outcomes among men with spinal cord injury

Purpose. Few studies have considered the impact of masculine role variables on outcome and adjustment to SCI among men. The present study examined the relations among SCI, views of masculinity, psychological adjustment, and rehabilitation outcomes among men with SCI.

Method. The sample included 20 men with SCI receiving inpatient rehabilitation, with a mean age of 45 years. Data included demographic variables as well as Conformity to Masculine Norms Inventory (CMNI), Gender Role Conflict Scale (GRCS), Functional Independence Measure (FIM), and Satisfaction with Life Scale ratings, and change in marital status.

Results. The findings revealed that satisfaction with life was positively related to scores on the CMNI Violence scale, FIM change from admission to discharge was positively related to the CMNI Emotional Control scale and negatively related to the CMNI Dominance scale. Change in marital status was inversely related to the CMNI Emotional Control and Primacy of Work scales and the GRCS Restricted Emotionality and Power, Success, and Competition scales.

Conclusions. The findings show that certain aspects of the traditional masculine role (i.e., ability to modulate strong emotions) may be adaptive in the rehabilitation process, whereas other aspects (i.e., a dominant interpersonal style) may present a barrier to effective rehabilitation.     

Five-year experience with the 'Sheba' model of comprehensive orthogeriatric care for elderly hip fracture patients

Background and purpose: The Sheba model of orthogerioatric medicine is a unique model of in-hospital care for elderly hip fractured patients, based upon the concept that a hip fracture represents a geriatric, rather than an orthopedic disease. The nature and feasibility of such a comprehensive orthogeriatric unit, taking care of all surgical, medical and rehabilitation needs, in a single geriatric-based setting (rather than orthopedic-based), were questioned. The aim of the study is to describe the results of its operation during a five-year period.

Method: A retrospective charts analysis of consecutive older patients with hip fractures, admitted from the emergency unit directly to the orthogeriatric unit of a department of geriatric medicine.

Results: A total number of 592 patients were admitted. Mean age of patients was 83.2 years, mostly women. A total of 538 (91%) were treated surgically. Delay to surgery was 3.6 ± 2.9 days. A total of 65.6% were suitable for rehabilitation, and had a mean Functional Independence Measure (FIM) gain of 22.3 ± 7.9. Mean total hospital length of stay was 29.9 days and 68.7% of patients returned to their previous living residence. Rates of major complications (4.1%) and in-hospital mortality (3.2%, equivalent to 30 days mortality) were low.

Conclusions: Treatment within this unit was associated with low rates of major morbidity and mortality, short stay and acceptable functional outcomes. The data provide clinical evidence supporting the implementation of this model of comprehensive orthogeriatric care, being a practical, applicable and feasible service for elderly hip fractured patients, and covering the various needs of these patients. The present model of organization could also help in skillful use of economic resources, facilitating effective treatment strategies.     

Pain perception during the rehabilitation phase following traumatic hip fracture in the elderly is an important prognostic factor and treatment tool

Purpose.?To evaluate the role of pain perception on admission to geriatric rehabilitation on the functional recovery after rehabilitation treatment in elderly patients with hip fracture and on the length of stay.

Method.?One hundred and sixty-five community dwelling elderly 65-year-old and over (mean age of 78 years), following recent operated traumatic hip fracture without clinical evidence for another acute medical or surgical condition were assessed regarding age, sex, chronic medical conditions, pre-fracture functional status, type of fracture and of operation, pain perception, and cognitive status. Pain was measured using the Visual Analogue Score (VAS). Functional status was measured using the Functional Independence Measurement (FIM). Activities of Daily Living (ADL) were assessed using the Katz index.

Results.?The average VAS score on admission was 7.38 ± 1.20 and on discharge 3.67 ± 1.18. Pain on admission inversely correlated to family support, function prior to fracture and cognitive status on admission, and correlated positively with depressed mood. With every increase of one point in VAS on admission above 4 points, the FIM on discharge decreased by 8.77 and the length of stay increased by 4.76 days.

Conclusions.?Pain intensity may add a valuable dimension for the prognostic evaluation of the patients with hip fractures. Inadequate early patient assessment and associated treatment impact on the patients' functional outcome, prolonged duration of rehabilitation treatment, and therefore, in addition to socio-economic effect, increase the cost to the local health care setting.     

Effects of training and detraining on the static and dynamic balance in elderly fallers and non-fallers: a pilot study

Purpose. The aim of this study was to evaluate the effects of training based on static and dynamic balance in single and dual task conditions in order to analyse the effects of detraining on static and dynamic balance in healthy elderly fallers and non-fallers.

Method. A group of 16 subjects were trained: eight fallers aged 71.1 ± 5.0 years and eight non-fallers aged 68.4 ± 4.5 years. The subjects were evaluated 3 months before the training period, 2 days before the training period, 2 days after the end of the training period and 3 months after the training period. All subjects performed a unipedal test with eyes open and eyes closed. Gait parameters were analysed under single-task and dual motor-task conditions.

Results. This study demonstrated a loss of physical capacities over 3 months for stride time, single support time for fallers in both conditions. Physical training significantly improves static and dynamic balance under single and dual task conditions. Lastly, after 3 months of detraining, a loss of the physical training effects were measured for fallers and non-fallers on the different walking parameters in the two conditions and on the unipedal tests.

Conclusions. The absence of stimulation before the trained period shows a negative effect of ageing on walking and falls whereas training permits an improvement in static balance and the pattern of walking under single and dual task conditions, which could be due to an increase in muscular strength and a better division of attention. On the other hand, 3 months of detraining inhibited the effects of training, which showed the speed of the decline caused by 'natural' ageing.     

Evaluation of patient education in spinal cord injury rehabilitation: knowledge, problem-solving and perceived importance

Purpose. Through inpatient education programmes the person with spinal cord injury (SCI) learns to understand and monitor his or her own physical, emotional and social well-being. The purpose of this study was to determine the patients' knowledge and problem-solving skills regarding SCI at admission, discharge and follow-up at 6 months after discharge; and to determine the perceived importance of each content topic included in the education programme.

Methods. A one-group repeated measures design was used to evaluate the outcomes. Knowledge was evaluated with a Multiple Choice Questionnaire (MCQ). Problem-solving ability based on participants' responses to Life Situation Scenarios relevant to each topic area was rated on a standardized four-point criterion reference scale. Perceived importance for each topic area was rated on a five-point Likert scale.

Results. Twenty-three participants completed all assessments. There was significant improvement in MCQ scores from admission to discharge (P = 0.04) and admission to follow-up (P = 0.02). For problem-solving ability, there was a trend toward improvement in all content topics with significant improvement from admission to follow-up for the topic of bowel care (P = 0.004). However, many participants continued to demonstrate poor problem-solving ability. Bowel, Bladder and Skin Care were consistently perceived as the most important education topics.

Conclusions. Improvements in knowledge do not necessarily translate to improvements in problem-solving ability even for the topics perceived as important. This may indicate the need to incorporate more active learning strategies or contextually based strategies within patient education programmes to facilitate the transfer of knowledge within life situations.     

Perceptual-motor coordination in persons with mild intellectual disability

Background. There is limited experimental evidence to support the view that individuals with intellectual disabilities (ID) have a deficit in motor control. This work is a first attempt to evaluate their motor coordination.

Purpose. The study assessed the relationship between cognitive ability and sensorimotor integration. The clinical hypothesis is that adults with ID fall below non-ID adults in motor skills that involve hand-eye coordination.

Method. A group of 42 adults with ID (ID group) was compared to 48 age-matched typical adults (TA) using a mixed experimental design ('Task' as the within-subjects factor and 'Group' as the between-subjects factor). Participants performed the following tests twice: Box-and-Blocks, 25-Grooved-Pegboard, Stick Catching and overhead Beanbag-Throw. Pearson correlations and ANOVAs were used to test the hypothesis (p ≤ 0.05).

Results. As expected, TA outperformed the ID group in all tests regardless of the hand used during for the assessment. However, TA individuals scored significantly better with one hand (i.e., the preferred and dominant hand) as opposed to persons with ID, who exhibited no hand preference. Test-retest correlations among the first and second assessment scores yielded moderate-strong coefficients, depending on the type of test (Box-and-Blocks = 0.92 and 0.96, 25-Grooved-Pegboard = 0.69 and 0.83, Stick-Catching = 0.88 and 0.94, Beanbag-Throw = 0.58 and 0.91 for ID and TA, respectively).

Discussion. Difficulties in the integration of perceptual information into motor action may result in inadequate solutions to daily motor problems. As it stems from our results, intellectual disability relates to inability to integrate visual inputs and hand movements. In people with mild ID such inability is observed using both hands (i.e., they show no hand preferences). Poor perceptual-motor coordination might have a functional significance in that it may lead to exclusion from vocational and recreational activities, and a decreasing competence of ADL. Assessing coordination in adults with ID may contribute to understanding the nature of the ID condition and may encourage an early rehabilitation.     

Gender differences in amputation outcome

Purpose. To assess the influence of gender on the success of limb-fitting after amputation.

Methods. One-hundred and five successive in-patients admitted to an amputee rehabilitation ward were followed to assess the success of limb-fitting at discharge. The influence of demographic, clinical and social factors on the success of lower limb-fitting was assessed using linear regression analysis and group comparisons.

Results. There were 35 (33%) women in a cohort of 105 successive admissions. Men and women were comparable in terms of age, length of stay, medical comorbidity and level of amputation. Women were less likely to be successfully fitted with a prosthetic limb at discharge than men (42.9% vs 68.6%, p = 0.011), and more women lived alone (57.1% vs 38.6%, p = 0.021). Linear regression revealed that gender was an independent significant factor in the success of limb-fitting; age, level and cause of amputation, co-morbidity and length of stay were not significant factors.

Conclusions. Women were less likely to be successfully fitted with a lower limb prosthesis after amputation.     

Reduction of disability after stroke is a more informative predictor of long-time survival than initial disability status

Purpose. Few studies have evaluated the roles of reducing disability after stroke in predicting survival. This study aimed to investigate the effects of improvement in the Barthel Index (BI) and other prognostic factors on survival in patients with first-time noncardioembolic ischemic stroke.

Method. BI effectiveness was defined as the improvement of BI between initial stroke (within 3 days) and 2 months after stroke. Cox regression analysis and Kaplan-Meier methods were used to evaluate the predictive roles of various prognostic factors.

Results. A total of 111 patients were enrolled. Mean age at the time of stroke was 68 (±11.2) years. Median follow-up time was 77.4 months. Mean initial BI was 36.1 (±28.5) and mean BI effectiveness was 46.9 ± 29.0. Overall, 55 deaths (49.5%) of the cohort were ascertained. The BI effectiveness had significant effects on long-time survival while initial BI was not a significant predictor. Higher BI effectiveness led to lower risk of mortality (hazard ratio = 0.44, 95% CI 0.24 - 0.80, p = 0.007). Elder age was correlated with poor survival (overall p = 0.006). Subjects in the eldest age group (≧70 years) showed a significant elevated risk for death (hazard ratio = 3.42, 95% CI 1.18 - 9.92). There was a trend indicating that the smaller the lesion size, the more favourable the prognosis (overall p = 0.057).

Conclusions. BI effectiveness in the first 2 months after first-time noncardioembolic stroke was more informative than initial disability status for predicting long-time mortality. It highlights the potential benefit in maximizing functional performance in patients with stroke.     

Adapting the Canadian Occupational Performance Measure for use in a paediatric clinical trial

Background. The Canadian Occupational Performance Measure (COPM) is a commonly used outcome measure in rehabilitation. In this study it was adapted for very young children by deleting paid/unpaid work and household management categories and having parents act as proxies to rate child performance and their own satisfaction.

Purpose. To assess the internal consistency reliability, content and construct validity, responsiveness, and impact of half scores (20 not 10-point scale) of the adapted COPM.

Method. Parent proxies of subjects aged 2 - 8 (mean 3.9) years with spastic hemiplegic cerebral palsy (n = 41) participating in a clinical trial. There was a total of 214 occupational performance problems for analysis and an additional 56 which had used half score ratings. Internal consistency reliability and construct validity were evaluated using Cronbach alpha statistic. Proxy views explored content validity. Responsiveness was evaluated using pre-post intervention scores and a comparison with Goal Attainment Scaling scores which were assumed to be a suitable benchmark measure. The effect of half scores was assessed by two-sample t-tests.

Results. The COPM adaptations did not have a negative impact on internal consistency reliability as this was acceptable for performance (0.73) and satisfaction (0.83). The high Cronbach alpha scores indicated good construct validity. Content of occupations and rating approach was considered valid by proxies. Use of half scores did not result in significantly different performance ratings, but mean satisfaction ratings were significantly higher when half scores were used (p = 0.0001). This suggests that half scores may provide more precise proxy satisfaction ratings, but at the cost of rigour as internal consistency with satisfaction half scores was lower (0.63 vs. 0.82). Responsiveness to change in clinical status was demonstrated by significant pre-post scores and moderate correlations with goal attainment scores.

Conclusion. The adapted COPM is a psychometrically robust tool and the use of half scores is not recommended.     

Gait during hydrokinesitherapy following total knee arthroplasty

Purpose. To obtain gait parameters during hydrotherapy (HT) in patients who were referred for rehabilitation after primary total knee arthroplasty (TKA).

Method. The study had a cohort prospective design. Patients who had undergone TKA followed a HT rehabilitation programme. Twenty-two consecutive patients were enrolled. Four of them dropped out for various reasons, independently of HT. Therefore 18 patients could be evaluated (5 men and 13 women). Eighteen age-matched healthy volunteers were the control subjects. Nine patients had a right TKA and nine a left TKA. On the average HT duration was 18.4 days (SD 1.4).

Results. The patients presented with a mean speed of 912 (SD 275) meters per hour (m/h) at the baseline. At the last session the mean speed was 1330 (SD 416) m/h. The mean stance duration was 1.75 s (SD 0.34) on the operated side and 1.83 s (SD 0.41) on the non-operated side. By contrast, the mean swing duration was 1.10 s (SD 0.25) on the operated side and 1.13 s (SD 0.34) on the non-operated side. The step duration was the same on both sides. At the beginning of HT the mean stance/swing ratio was 1.94 on the operated side, whereas it was 1.77 on the non-operated side. In the controls the ratio was 1.46. At the beginning the mean stride length was 0.526 m (SD 0.147) and the value became 0.556 (SD 0.138) after 18 training sessions. At the individual level, recovery occurred in a non-linear fashion (Best Fitting, 7th-grade Fourier finite series).

Conclusions. The study design permits accurate definition of stride parameters during rehabilitation which allows optimization of the programme. Increase in speed and regain of balance are the main targets of a HT programme and are monitored on a daily basis.     

Reduced community integration in persons following traumatic brain injury, as measured on the Community Integration Measure: an exploratory analysis

Purpose. To explore the community integration of individuals who had suffered a Traumatic Brain Injury (TBI) and compare this to members of the general public.

Method. An independent groups design explored differences in three groups' levels of community integration. These groups consisted of ten survivors of TBI, ten male and ten female controls and were measured using The Community Integration Measure (CIM). All participants were resident in Northern Ireland (NI). The brain injured participants were drawn from a Belfast-based social skills programme.

Results. Mann-Whitney U tests showed a statistically significant difference between female controls and brain-injured individuals (U = 26.50, N₁ = 10, N₂ = 10, p = 0.037, one-tailed).

Conclusion. Females were more integrated into their communities than males, who were, in turn, more integrated than brain injured individuals. It would appear that brain injury survivors are doubly disadvantaged. Their gender (mainly male), and the injury itself, conspire to reduce their integration within the wider community.     

Evaluation of prosthetic usage in upper limb amputees

Purpose: Upper limb amputations cause severe functional disability and lower the patient's self body image, with severe psychological implications. Many parameters are involved in the successful rehabilitation of upper limb amputations. The aim of this study was to investigate whether there are any parameters that might predict the successful prosthetic rehabilitation of upper limb amputees.

Method: The records of 45 patients who had undergone an upper limb amputation were traced. The patients were evaluated according to four parameters: (1) Modified upper extremities amputees' questionnaire; (2) Pain level according to Visual Analog Scale (VAS), range from 1 (lowest) up to 10 (highest); (3) Pain type - phantom or pain in the stump; (4) Functional assessment of prosthetic usage.

Results: Thirty (71.43%) of the patients reported difficulties with prosthesis usage. Twenty-three patients (54.76%) were satisfied with their prosthesis - 19 had cosmetic prosthesis and four had body-powered prosthesis.

Conclusion: No significant affect of the amputation level except for trans-wrist amputation with 100% prosthesis use. No significant difference was found between prosthesis type and the correlation to stump problems.

The above-elbow amputees, with dominant hand amputation, who used functional prosthesis (body-powered), achieved the best functional outcome and result.     

A pilot study of a web-based physical activity motivational program for adults with physical disabilities

Purpose. Develop, deliver, and assess the efficacy of a 4-week web-based leisure-time physical activity (LTPA) motivational program based on the Transtheoretical Model and tailored to inactive adults with physical disabilities.

Method. This was a pilot-based study incorporating a true experimental design with one treatment and one control group. The intervention program was delivered on the web and was based on the constructs of the Transtheoretical Model. From the 151 individuals who completed the LTPA standardized questionnaire at baseline, 75 people participated in the 1-month post-test assessment.

Results. The results of the analysis confirmed the pretest LTPA scores as the study covariate for the post-test assessment (F (1,72) = 16.06, p = 0.001, η² = 0.18). Based on the one-way ANCOVA, there were no statistically significant differences in LTPA scores between the treatment and control groups at post-test. However, the corresponding effect size and variance explained by the treatment approached a moderate level of significance (d = 0.34 and η² = 0.04).

Conclusions. Although conclusive statements about program effectiveness cannot be secured, several 'lessons learned' from this project may be 'key factors' for program improvement. Given the pilot nature of the study and the limited resources for program development and monitoring, continued examination of such motivational materials and delivery mechanisms for people with physical disabilities appear warranted.     

Comparison between performance with a pushrim-activated power-assisted wheelchair and a manual wheelchair on the Wheelchair Skills Test

Purpose. To test the hypothesis that people using a pushrim-activated power-assisted wheelchair (PAPAW) can accomplish a wider range of wheelchair skills than when using a manual wheelchair (MWC).

Methods. We studied 30 able-bodied participants, using within-participant comparisons. Participants used a manual wheelchair equipped with both PAPAW and regular MWC rear wheels, and rear anti-tip devices (Arc-RADs) that permitted wheelie-like function. We trained participants to perform the wheelchair skills of the Wheelchair Skills Training Program (WSTP, Version 2.4). From the Wheelchair Skills Test (WST, Version 2.4), we calculated pass-fail success rates for the 50 individual skills and a total percentage WST score.

Results. The mean (±SD) total WST scores were 89.3 (±7.0)% for the PAPAW and 88.8 (±8.4)% for the MWC, with a mean difference of 0.6 (±5.6)% (p = 0.59). Qualitative observations suggested that skills requiring a higher force on the pushrim (e.g., incline ascent) were performed more easily with the PAPAW, whereas skills requiring greater control of the wheelchair (e.g., wheelie-dependent skills) were performed more easily with the MWC.

Conclusion. Overall wheelchair skill performance with the PAPAW is not superior to that when using the MWC. The PAPAW may be helpful for specific skills that require more wheel torque, but the additional torque appears to be disadvantageous when performing skills that require greater control.     

The Papworth Early Rehabilitation Programme: vocational outcomes

Background. There are 2.7 million people in the UK receiving incapacity benefits, costing approximately £18 billion pa. Government has adopted a policy of helping claimants back into work, through structured vocational rehabilitation schemes. There are no published results of vocational rehabilitation services in the UK. We present the results of the Papworth Trust vocational rehabilitation programme. Depending on the severity of their disability, the 'Early Rehab Programme' aims to get people on incapacity benefits: (a) into employment, (b) fit for and seeking work, (c) involved in voluntary work, (d) education, or (e) able to live independently.

Methods. Retrospective chart survey and telephone follow up.

Setting. Cambridgeshire.

Results. Since 1995, 274 people attended for a preliminary interview, of which 107 subsequently started a full rehab programme. Eighty-seven were male and 20 female. Half had been unemployed for more than two years. Ninety-four completed the programme, of whom 53 had gained employment, 33 were 'work ready' and four were doing voluntary work. At long-term follow-up, 52 were employed, 12 were in voluntary work, and 7 had retired on medical grounds.

Conclusions. This programme demonstrates that long-term Incapacity Benefit recipients can return to sustained employment, as shown in those who participated in the Papworth Trust's vocational rehabilitation programme.     

Gait in the early days after total knee and hip arthroplasty: a comparison

Purpose. To evaluate whether gait after Total Knee Arthroplasty (TKA) is different from gait after Total Hip Arthroplasty (THA) in the early days following surgical intervention.

Method. The gait was studied in water, thus exploiting its buoyancy force. Twenty consecutive patients underwent TKA and twenty consecutive patients underwent THA. The mean age was 70.2 years (SD 6.9). Twenty age-matched volunteers were the control group.

Results. At the beginning TKA and THA patients had the same speed and the same step length. At day 15 there was a speed difference in favour of THA patients (t = - 2.245, df 38, p = 0.031). Likewise, the step length was longer in THA patients (t = -2.293 df 38, p = 0.027). In contrast to TKA patients, THA patients were unbalanced, having a longer stance phase on the non-operated leg and a longer swing on the contralateral one.

Conclusions. Gait strategies were completely different after TKA and THA interventions. TKA patients were balanced over their feet and they appeared more cautious and more concerned about gait quality than moving quickly. By contrast, THA patients were unbalanced, having a longer stance phase on the non-operated leg and a longer swing on the contralateral one. However, their speed gain was higher.
