Abstract
Stooped posture, which is usually aggravated during walking, is one of the typical postural deformities in patients with parkinsonism. However, the degree of stooped posture is difficult to quantitatively measure during walking. Furthermore, continuous feedback on posture is also difficult to provide. The purpose of this study is to measure the degree of stooped posture during gait and to investigate whether vibration feedback from sensor modules can improve a patient's posture. Parkinsonian patients with stooped posture were recruited for this study. Two wearable sensors with three-axis accelerometers were attached, one at the upper neck and the other just below the C7 spinous process of the patients. After being calibrated in the most upright posture, the sensors continuously recorded the sagittal angles at 20 Hz and averaged the data at every second during a 6 min walk test. In the control session, the patients walked with the sensors as usual. In the vibration session, sensory feedback was provided through vibrations from the neck sensor module when the sagittal angle exceeded a programmable threshold value. Data were collected and analyzed successfully in a total of 10 patients. The neck flexion and back flexion were slightly aggravated during gait, although the average change was <10° in most patients in both measurement sessions. Therefore, it was difficult to evaluate the effect of sensory feedback through vibration. However, some patients showed immediate response to the feedback and corrected their posture during gait. In conclusion, this preliminary study suggests that stooped posture could be quantitatively measured during gait by using wearable sensors in patients with parkinsonism. Sensory feedback through vibration from sensor modules may help in correcting posture during gait in selected patients.

Abstract
BACKGROUND AND PURPOSE Flexed truncal posture is common in people with Parkinson disease (PD); however, little is known about the mechanisms responsible or its effect on physical performance. This cross-sectional study aimed to establish the reliability of a truncal posture measurement and explore relationships between PD impairments and truncal posture, as well as truncal posture and balance and mobility. METHODS A total of 82 people with PD participated. Truncal posture was measured in standing as the distance between vertebra C7 and a wall. Univariate and multivariate regression analyses were performed with truncal posture and impairments, including global axial symptoms, tremor, bradykinesia, rigidity, freezing of gait (FOG), reactive stepping and executive function, as well as truncal posture with balance and mobility measures. RESULTS The truncal posture measure had excellent test-retest reliability (ICC3,1 0.79, 95% CI 0.60-0.89, P < 0.001). Global axial symptoms had the strongest association with truncal posture (adjusted R = 0.08, P = 0.01), although the majority of the variance remains unexplained. Post hoc analysis revealed that several impairments were associated with truncal posture only in those who did not report FOG. Flexed truncal posture was associated with poorer performance of most balance and mobility tasks after adjustment for age, gender, disease severity, and duration (adjusted R = 0.24-0.33, P < 0.001-0.03). DISCUSSION AND CONCLUSIONS The C7 to wall measurement is highly reliable in people with PD. Global axial symptoms were independently associated with truncal posture. Greater flexed truncal posture was associated with poorer balance and mobility. Further studies are required to elucidate the mechanisms responsible for flexed truncal posture and the impact on activity.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A164).

Abstract
Objective: To determine the effectiveness of kayaking exercises in the management of axial rigidity, improve bed mobility by improving trunk rotation in Parkinson’s patients. Methods: Experimental randomized controlled trail conducted at Physiotherapy department of IPM&R, DUHS and neurology Outpatient Department of Civil Hospital Karachi. Sample size of 48 was calculated with the use of openEpi. After baseline assessment 24 participants were assigned to each Kayaking exercise and general mobility exercise groups. Both groups received treatment for 75 minutes, 6 days a week for 4 weeks. Pre and post treatment measurements were determined by goniometer that assessed the cervical and thoracolumbar rotations whereas bed mobility was assessed by Modified Parkinson’s Activity Scale (MPAS). Results: In Kayaking group mean cervical spine left rotation increased from 32.95+ 9.66 to 47.25 + 10.58, right side cervical spine rotation increased from 34.00 + 10.32 to 47.58 + 11.96, left side thoracolumbar rotation increased from 23.67 + 4.70 to 28.16 + 3.44, right side thoracolumbar rotation increased from 20.79 + 5.34 to 26.45 + 4.62. In control group mean cervical spine left rotation increased from 34.66+ 9.26 to 43.08 + 8.70, right side cervical spine rotation increased from 35.37 + 9.77 to 43.83 + 9.59 , left side thoracolumbar rotation increased from 23.70 + 4.77 to 26.87 + 3.73, right side thoracicolumbar rotation increased from 21.16 + 5.29 to 24.95 + 4.53 (P value <0.001).. Bed mobility on MPAS scale also showed significant improvements (P value <0.001). Conclusion: Both Kayaking and general exercises resulted in significant improvements after 4 weeks of treatment. However, Kayaking exercises were slightly more beneficial than general exercises.

Abstract
Symptoms of Parkinson's disease (PD) progress despite optimized medical treatment. The present study investigated the effects of a flexibility and relaxation programme, walking, and Nordic walking (NW) on walking speed, stride length, stride length variability, Parkinson-specific disability (UPDRS), and health-related quality of life (PDQ 39). 90 PD patients were randomly allocated to the 3 treatment groups. Patients participated in a 6-month study with 3 exercise sessions per week, each lasting 70 min. Assessment after completion of the training showed that pain was reduced in all groups, and balance and health-related quality of life were improved. Furthermore, walking, and Nordic walking improved stride length, gait variability, maximal walking speed, exercise capacity at submaximal level, and PD disease-specific disability on the UPDRS in addition. Nordic walking was superior to the flexibility and relaxation programme and walking in improving postural stability, stride length, gait pattern and gait variability. No significant injuries occurred during the training. All patients of the Nordic walking group continued Nordic walking after completing the study.

Abstract
Although Parkinson disease (PD) is common throughout the world, the evidence for physical therapy interventions that enable long-term improvement in walking is still emerging. This article critiques the major physical therapy approaches related to gait rehabilitation in people with PD: compensatory strategies, motor skill learning, management of secondary sequelae, and education to optimize physical activity and reduce falls. The emphasis of this review is on gait specifically, although balance and falls are of direct importance to gait and are addressed in that context. Although the researchers who have provided the evidence for these approaches grounded their studies on different theoretical paradigms, each approach is argued to have a valid place in the comprehensive management of PD generally and of gait in particular. The optimal mix of interventions for each individual varies according to the stage of disease progression and the patient's preferred form of exercise, capacity for learning, and age.

Abstract
The primary impairments associated with Parkinson's disease occur in combination with the secondary, preventable effects of immobility. A community-based fitness program may help increase activity and maintain function in people in the early or middle stages of the disease. This article describes a unique program designed to reduce fall risk and promote independent exercise for people with Parkinson's disease. Two 66-year-old males, both community ambulators and in early or middle stages of Parkinson's disease, participated in 3 months of various physical activities. Group balance classes were held twice weekly during the first month, participants joined a fitness center and self-directed their exercise program during the second month, and group Tai Chi classes were held twice weekly during the third month. At conclusion of the program, participants were given suggestions for continued physical fitness activities. After the 3-month program, improvements were noted for both individuals in functional reach, Timed Up and Go, and Berg Balance scores. Both participants continued to exercise regularly for at least 8 months following the program. Two individuals with Parkinson's disease demonstrated improvement in their balance test performance over a 3-month period. Perhaps most importantly, these participants independently continued exercising after completing this program.

Abstract
We evaluated changes in different domains of quality of life (QL) for persons with Parkinson's disease after a program of physical activity. Twenty subjects with a diagnosis of Parkinson's disease classified as Stages 1 to 3 on the Hoehn and Yahr scale and with a mean age of 61.5 +/- 9.8 years participated in 36 group sessions of a combined group program of aerobic conditioning and muscular strengthening. QL was investigated by the Nottingham Health Profile, a generic questionnaire composed of six domains. Student's paired t tests indicated significant gains associated with the program (P < 0.05) on the total score and those related to emotional reactions (ER), social interactions (SI), and physical ability (PA). SI was the domain that showed the greatest program gains (41.4%). The program of physical activity performed with persons with Parkinson's disease at light to moderate stages resulted in improvements in their perception of QL, mainly in the domains of ER, SI, and PA.

Abstract
OBJECTIVE To investigate respiratory muscle strength in mild to moderate Parkinson's disease in comparison with prediction equations and age-matched controls. To identify correlations between respiratory muscle strength and daily living function, activity levels, quality of life, and exercise capacity. DESIGN A total of 66 participants with Parkinson's disease and 32 age-matched, healthy controls participated. Respiratory mouth pressures (representing respiratory muscle strength) were compared with predicted values. A comparison was also made between participants with Parkinson's disease and age-matched controls. Respiratory mouth pressures were correlated with results of the Barthel index (daily living function), a modified Baecke activity questionnaire (activity levels), the Parkinson's disease questionnaire (quality of life in Parkinson's disease), peak heart rate, peak oxygen consumption, blood lactate thresholds, and the number of stages completed during an incremental cycle ergometer test (representing exercise capacity). RESULTS Respiratory mouth pressures were significantly lower (P < 0.05) in the Parkinson's disease group, but this did not influence the measures of daily living function, activity levels, and quality of life. Respiratory mouth pressures correlated with lactate thresholds (r = 0.308, P < 0.01) and the number of completed stages of the cycle ergometer test (r = 0.490, P < 0.01). CONCLUSIONS In mild to moderate Parkinson's disease, there is a significant weakness of the respiratory muscles. This can affect the individual during exercise but has no apparent effect on activities that do not require a large effort of the respiratory muscles.

Abstract
OBJECTIVE To assess immediate and near-term effects of 2 exercise training programs for persons with idiopathic Parkinson's disease (IPD). DESIGN Randomized control trial. SETTING Public health facility and medical center. PARTICIPANTS Fifteen persons with IPD. INTERVENTION Combined group (balance and resistance training) and balance group (balance training only) underwent 10 weeks of high-intensity resistance training (knee extensors and flexors, ankle plantarflexion) and/or balance training under altered visual and somatosensory sensory conditions, 3 times a week on nonconsecutive days. Groups were assessed before, immediately after training, and 4 weeks later. MAIN OUTCOME MEASURES Balance was assessed by computerized dynamic posturography, which determined the subject's response to reduced or altered visual and somatosensory orientation cues (Sensory Orientation Test [SOT]). Muscle strength was assessed by measuring the amount of weight a participant could lift, by using a standardized weight-and-pulley system, during a 4-repetition-maximum test of knee extension, knee flexion, and ankle plantarflexion. RESULTS Both types of training improved SOT performance. This effect was larger in the combined group. Both groups could balance longer before falling, and this effect persisted for at least 4 weeks. Muscle strength increased marginally in the balance group and substantially in the combined group, and this effect persisted for at least 4 weeks. CONCLUSION Muscle strength and balance can be improved in persons with IPD by high-intensity resistance training and balance training.

Abstract
OBJECTIVE To evaluate the short-term effectiveness of an intensive multidisciplinary rehabilitation programme for people with Parkinson's disease and their carers. DESIGN Observational, with assessments before and after intervention. SETTING An elderly care day unit in a district general hospital in south-east England. SUBJECTS One hundred and eighteen people with Parkinson's disease and no cognitive impairment, and their carers. INTERVENTION Participants attended the day hospital in groups of six patients with their carers for one day per week over six consecutive weeks. After assessment, they received individual treatment from a specialist team. Weekly group activities included relaxation and talks from experts. OUTCOME MEASURES Patients and carers were assessed for: health-related quality of life, psychological well-being, social services need, perceptions of the programme. Patients were additionally assessed for mobility, gait and speech. Carers were assessed for strain. RESULTS After treatment significant improvements were recorded in patients' mobility and gait (p < 0.05), speech (p < 0.001), depression (p = 0.029), health-related quality of life (p = 0.001). People with more advanced disease at baseline gained significantly more from treatment (p < or = 0.04). Carers were less depressed and had higher health-related quality of life than patients at baseline (p < 0.001) and no improvements in these indicators were recorded after treatment. A high unmet need for social services was identified in 31% of participants, and 10% of carers were found in danger of being unable to continue caring. Participants reported knowledge gains and high levels of satisfaction with both individual therapies and group activities. CONCLUSIONS This intensive co-ordinated programme provided immediate benefits to people with Parkinson's disease and their carers.

Abstract
BACKGROUND AND PURPOSE Evidence suggests that individuals with early and mid-stage Parkinson disease (PD) have diminished range of motion (ROM). Spinal ROM influences the ability to function. In this investigation, the authors examined available spinal ROM, segmental excursions (the ROM used) during reaching, and their relationships in community-dwelling adults with and without PD. SUBJECTS The subjects were 16 volunteers with PD (modified Hoehn and Yahr stages 1.5-3) and 32 participants without PD who were matched for age, body mass index, and sex. METHODS Range of motion of the extremities was measured using a goniometer, and ROM of the spine was measured using the functional axial rotation (FAR) test, a measure of unrestricted cervico-thoracic-lumbar rotation in the seated position. Motion during reaching was determined using 3-dimensional motion analysis. Group differences were determined using multivariable analysis of variance followed by analysis of variance. Contributions to total reaching distance of segmental excursions (eg, thoracic rotation, thoracic lateral flexion) were determined using forward stepwise regression. RESULTS Subjects with PD as compared with subjects without PD had less ROM (FAR of 98.2 degrees versus 110.3 degrees, shoulder flexion of 151.9 degrees versus 160.1 degrees) and less forward reaching (29.5 cm versus 34.0 cm). Lateral trunk flexion and total rotation relative to the ground contributed to reaching, with the regression model explaining 36% of the variance. DISCUSSION AND CONCLUSION These results contribute to the growing body of evidence demonstrating that spinal ROM is impaired early in PD.

Abstract
At the beginning of the 1970s, different studies reported behavioural disturbances after the intracerebroventricular (icv) administration of 6-hydroxydopamine (6-OHDA) in the rat. Despite the fact that this neurotoxic agent degenerates brain dopaminergic (DA-) cells, its potential utility to produce a rat model of Parkinson's disease (PD) was never systematically studied because the aphagia and adipsia were often observed. In the present study, a procedure that induces a marked DA-cell degeneration that bypasses these and other undesirable complications of icv injection of 6-OHDA is reported. Lesioned animals (50-500 microg of 6-OHDA) showed a persistent motor syndrome composed of hypokinesia, purposeless chewing and catalepsy. The intensity of motor signs was dose-dependent, and recovered partially after administration of DA-receptor agonists, exposure to sensorial stimuli and stress, three procedures that reduce motor dysfunctions in Parkinson's disease (PD). Lesioned animals showed bilateral and symmetrical midbrain DA-cell degeneration with the highest cell-loss in A9 group (substantia nigra), followed by A8 (retrorubral field) and A10 (ventral tegmental area) groups. The similarity between the behavioural syndrome and the topographical profile of cell-loss after icv injection of 6-OHDA in rats and the clinical and neuropathological features of PD indicates that this may be a convenient animal model of PD particularly useful for checking in rats the possible efficacy of new anti-parkinsonian drugs on specific parameters of motor dysfunctions.

Abstract
BACKGROUND One area of research that requires further elaboration is the relationship between impairments and functional limitations. By identifying specific contributors to functional limitations, it may be possible to establish intervention strategies, including exercise approaches, that can delay or ameliorate decline in function. The association between impaired spinal flexibility and functional limitations has not been studied in depth. The purposes of this study were to determine (a) the associations between spinal flexibility and functional limitations; (b) the relative contribution of spinal flexibility to specific functional limitations; and (c) how disease state (Parkinson's disease [PD] vs no PD) modified these relationships. METHODS Participants included 251 community-dwelling adults, 56 of whom were with diagnosed PD and 195 were without PD or other specific disorders. Measures included spinal flexibility (i.e., functional axial rotation [FAR]) and configuration (i.e., thoracic kyphosis and lumbar lordosis), functional limitations (i.e., functional reach, supine-to-stand time, 10-m walk, and 360 degrees turn). RESULTS Canonical correlation (Can R) demonstrated significant associations between spinal measures and functional limitations (Can R = .488, p = .0001). After controlling for age, gender, race, body mass index, comorbidity, confidence, and depression, a multivariate regression model demonstrated that spinal flexibility contributed significantly to functional reach (R2 = .334 for the overall model, p = .0001). Based on the parameter estimate of 0.026, the results prediet that FAR accounts for a 4.6-inch difference in reach distance between the least and most flexible of the participants. In addition, there were significant differences between almost all measurements for the PD compared with the non-PD participants. CONCLUSION Results clearly implicate spinal flexibility as a contributor to functional reach, a measure of functional limitation and an established measure of balance control. Further work is needed to determine the extent to which spinal flexibility can be improved and the effect of that improvement on balance.

Abstract
Abstract
People who are diagnosed with idiopathic Parkinson disease (PD) experience movement disorders that, if not managed, can lead to considerable disability. The premise of this perspective is that physical therapy for people with PD relies on clinicians having: (1) up-to-date knowledge of the pathogenesis of movement disorders, (2) the ability to recognize common movement disorders in people with PD, (3) the ability to implement a basic management plan according to a person's stage of disability, and (4) problem-solving skills that enable treatment plans to be tailored to individual needs. This article will present a model of physical therapy management for people with idiopathic PD based on contemporary knowledge of the pathogenesis of movement disorders in basal ganglia disease as well as a review of the evidence for physical therapy interventions. The model advocates a task-specific approach to training, with emphasis on treating people with PD-related movement disorders such as hypokinesia and postural instability within the context of functional tasks of everyday living such as walking, turning over in bed, and manipulating objects. The effects of medication, cognitive impairment, the environment, and coexisting medical conditions are also taken into consideration. An argument is put forward that clinicians need to identify core elements of physical therapy training that apply to all people with PD as well as elements specific to the needs of each individual. A case history is used to illustrate how physical therapy treatment is regularly reviewed and adjusted according to the changing constellation of movement disorders that present as the disease progresses.

Abstract
OBJECTIVES The effectiveness of an exercise intervention for people in early and midstage Parkinson's disease (stages 2 and 3 of Hoehn and Yahr) in improving spinal flexibility and physical performance in a sample of community-dwelling older people is described. DESIGN AND SETTING Fifty-one men and women, aged 55-84 years, identified through advertisement, local support groups, and local neurologists were enrolled into a randomized, controlled trial. Subjects were assigned randomly to an intervention or a usual care arm (i.e., no specific exercise). Of the original 51 participants, 46 completed the randomized, controlled trial. Participants in the exercise arm (n = 23) received individual instruction three times per week for 10 weeks. Participants in the usual care arm (n = 23) were "wait listed" for intervention. MEASUREMENTS Changes over 10 weeks in spinal flexibility (i.e., functional axial rotation) and physical performance (i.e., functional reach, timed supine to stand) were the primary outcome measures. RESULTS MANOVA conducted for the three primary outcome variables demonstrated significant differences (P < or = .05) between the two groups. Further analysis using ANOVA demonstrated significant differences between groups in functional axial rotation and functional reach for the intervention compared with the control group. There was no significant difference in supine to sit time. CONCLUSION Study results demonstrate that improvements in axial mobility and physical performance can be achieved with a 10-week exercise program for people in the early and midstages of PD.

Abstract
This study assesses functional ability of Parkinson's disease (PD) patients by means of an objective movement analysis (the PLM-test) and three clinical tests. The correlation between the tests was also studied. The main object of this study was to detect and measure relevant disabilities in Parkinson's disease to obtain a clinical test battery.

Abstract
Pulmonary dysfunction was investigated in fifty-eight Parkinson's patients. Clinical disability was assessed by the Unified Parkinson's Disease Rating Scale. Pulmonary dysfunction was studied by spirometry with flow-volume loops, body plethysmography with lung volumes computation and maximal inspiratory and expiratory static mouth pressures. Forced vital capacity (FVC), forced expiratory volume in 1 min (FEV1), FEV1/FVC% and arterial PO2 and PCO2 were significantly below normal values. Residual volume (RV) and total rows were above normal values. Thirty-six had upper airway obstruction as judged by inspiratory flow peaks (PIF) < 3 l/s and FEV1/PEF (expiratory flow peak) > 8.5 l/min and MEF50/MIF50 > 1. Eighteen patients had a central (FEV1 < 80% and FEV1/FVC% < 80% of normal values) or peripheral (maximal expiratory flow between 75% and 25% of FVC and maximal expiratory flow after expiration of 50% below 70% of normal values) obstructive pattern. Sixteen patients had a restrictive dysfunction as judged by a total lung capacity < 85% or FVC < 80% with FEV1/FVC% > 80%. Sixteen patients had air trapping (RV > 120% and RV/TLC > 40%) and seven patients had lung insufflation (TLC > 120%). Rigidity, Rx signs of cervical arthrosis and limitations for passive movement of neck were higher in patients with central or peripheral airway obstruction. Bradykinesia and Rx signs of dorsal arthrosis was higher in patients with upper airway obstruction. Restrictive dysfunction was not related to tremor, rigidity or bradykinesia. The present data support the hypothesis that Parkinson patients present a high risk for pneumologic disturbances. These pulmonary dysfunctions are induced by the simultaneous action of a group of factors including the degree of bradykinesia or rigidity and the musculoskeletal limitations of vertebral column probably induced by chronic anomalous posture.

Abstract
OBJECTIVE The purpose of this study was to determine in Parkinson disease the impact of pulmonary dysfunction on daily living activities (DLA). PATIENTS Extrapyramidal motor impairment, pulmonary dysfunction, and DLA disabilities were studied in 58 Parkinson patients consecutively enrolled in a rehabilitation service at a university hospital. MAIN OUTCOME MEASURES Extrapyramidal motor impairments were assessed by the Unified Parkinson's Disease Rating Scale (UPDRS) and the DLA disabilities by the UPDRS, Hoehn-Yahr, and Schwab-England scales. The pulmonary dysfunctions were assessed by spirometry with flow-volume loops, body plethysmography with lung volumes computation, and maximal inspiratory and expiratory static mouth pressures. RESULTS Parkinson patients showed important modifications of pulmonary function with a decrease in forced vital capacity, forced expiratory volume in the first minute, and arterial PO2, and an increase in residual volume and total airway resistance (RAW). In addition, they showed a high incidence of airway ventilatory obstructions and restrictive dysfunction. The impact of lung disease on daily living activities in Parkinson disease patients was higher in subjects with restrictive pulmonary dysfunctions (Schwab-England test and turning in bed and adjusting bedclothes, walking, falling, and freezing when walking items of UPDRS) and airway obstructions (handling utensils, dressing and hygiene items of UPDRS). CONCLUSIONS Airway obstructions or restrictive pulmonary dysfunctions present a high prevalence in Parkinson disease, contributing as a main factor for DLA dysfunctions. The evaluation and rehabilitation of respiratory disturbances should be systematically included in the management of these patients.
