Purpose: Persons with disabilities affecting lower-limb function use ankle- foot-orthoses (AFO) and knee-ankle-foot-orthoses (KAFO) on a regular basis. However, the effectiveness of these devices in daily use is seldom evaluated, especially in the developing world. This study aimed to evaluate user satisfaction with lower-limb orthotic devices while performing a broad spectrum of daily life activities in Pakistan, and to document the desired outcomes.

 

Method: A survey was conducted among orthotic device users in the out-patient departments of three hospitals in Lahore, Pakistan. The survey questionnaire was devised by adapting the Prosthetic Evaluation Questionnaire to suit orthotics evaluation. Fifty-four AFO and KAFO users participated in the study.

 

Results: Most users felt comfortable while walking on even surfaces with their orthoses. However, donning/doffing these, climbing stairs and performing certain routine activities were considered problematic for most people. Energy conservation was the most desired AFO feature, while the KAFO users wanted automatic knee-joint function.

 

Conclusion and Implications: Overall satisfaction with the existing lower- limb orthoses is adequate. Yet, significant improvements are needed in terms of energy efficiency and comfort while walking on different terrains. Further research is required in order to improve the functioning of the existing orthotic devices.

Purpose: Post-polio Syndrome (PPS) affects polio survivors many years after the initial attack, and causes new musculoskeletal symptoms and decline in physical function. This study aims to compare the effect of exercise and lifestyle modification versus lifestyle modification alone, on fatigue and functional capacity in persons with PPS.

 

Method: An experimental study was conducted at the physiotherapy department of VS Hospital in Ahmedabad. As per the criteria of Halstead (1985), 21 PPS subjects who were between 18 and 65 years of age, and able to walk indoors and outdoors, with or without assistive aids, were included. They were randomly allocated into 3 groups using the envelope method. Those with physician- diagnosed respiratory or cardiac insufficiency, disabling co-morbidity which interfered with the intervention programme or influenced the outcome, and those unable to cooperate due to cognitive impairment or use of any psychotropic drugs, were excluded. Fatigue and functional capacity were measured using Fatigue Severity Scale (FSS) and 2-minute walk distance, respectively. Physical and psychological functions were assessed using Patient Reported Outcome Measurement Information System (PROMIS) questionnaire and Patient Health Questionnaire (PHQ-9) respectively. Intervention was given for 5 days a week, over 4 weeks. Group A received exercise and lifestyle modification, group B received lifestyle modification alone and group C continued their usual routine for 1 month.

 

Results: There was a significant difference in fatigue and functional capacity within groups A and B, with group A showing better reduction in fatigue than groups B or C. Physical function improved only within group A, and a significant difference was seen compared to groups B and C. Psychological function showed no difference within or between the groups.

 

Conclusion: There was improvement in fatigue, functional capacity and physical function in PPS subjects after 4 weeks of exercise and lifestyle modification. Lifestyle modifications alone for 4 weeks improved fatigue and functional capacity in PPS subjects. There is significant reduction in fatigue and improvement in functional capacity when lifestyle modification advice is given along with exercise.
