Although extensive literature exists on forward and backward walking, a comprehensive assessment of gait parameters on a wide and homogenous population is missing. Thus, the purpose of this study is to analyse the differences between the two gait typologies on a relatively large sample. Twenty-four healthy young adults participated in this study. By means of a marker-based optoelectronic system and force platforms, differences between forward and backward walking were outlined in terms of kinematics and kinetics. Statistically, significant differences were observed in most of the spatial–temporal parameters, evidencing some adaptation mechanisms in backward walking. Differently from the ankle joint, the hip and knee range of motion was significantly reduced when switching from forward to backward walking. In terms of kinetics, hip and ankle moment patterns for forward and backward walking were approximately mirrored images of each other. Moreover, joint powers appeared drastically reduced during reversed gait. Specifically, valuable differences in terms of produced and absorbed joint powers between forward and backward walking were pointed out. The outcomes of this study could represent a useful reference data for future investigation evaluating the efficacy of backward walking as a rehabilitation tool for pathological subjects.

Purpose: Forward Walking (FW) and Backward Walking (BW) on different gradients of the treadmill is a common exercise for lower extremity rehabilitation. However, limited studies are found about the three-dimensional analysis of lower extremity and status of the knee joint during FW and BW on different gradients. Therefore, this study aimed to investigate the lower extremity joints kinematics during FW and BW on incline and decline surfaces. Methods: The current research has a quasi-experimental design. Sixteen healthy males with the mean (SD) age of 22.4(2.5) years, volunteered to participate in this study. The subjects’ FW and BW with their preferred speed on a treadmill at four gradients (-7.5%, 0%, +5% and +10%), were analyzed by using motion capture system. All data were analyzed using paired sample t test (P

Context: Walking, both forward and backward, is found to be effective for reducing pain in subjects with osteoarthritis (OA) of the knee and improving physical function and quality of life (QOL). Aims: This study aims to determine and compare the effects of forward walking (FW) and backward walking (BW) on pain, physical function, and QOL in subjects with OA knee. Settings and Design: Quasi-experimental study set up at general hospital, Ahmedabad, India. Subjects and Methods: Thirty subjects >40 years diagnosed as having bilateral OA knee according to American College of Rheumatology criteria having indoor and outdoor walking ability without aids were included in this study. Group A and B subjects received FW and BW respectively for 10 min in addition to conventional treatment thrice daily for 2 weeks. Group C received conventional treatment in the form of hot water fomentation and exercises. Exercises comprised of static quadriceps, short arc terminal extension of the knee, ankle toe movements, straight leg raises, knee flexion and extension, proprioceptive exercises in the form of lunges, weight shifts, partial squats and balance training on the balance board and stretching of hamstrings, tendo-Achilles and rectus femoris muscles. Statistical Analysis Used: SPSS 16.0 (IBM Corporation). Parametric tests were used. The level of significance was 5%. Results: The results showed improvement in all the outcome measures within all the three groups. However, there was no statistically significant difference between the groups except Western Ontario and McMaster Universities Arthritis Index (WOMAC). Visual analog scale (VAS) at rest on the right side in all three groups and on the left side in Group A as well as in scores of VAS at activity on both the sides (P < 0.05) and no improvement in VAS at rest on the left side in Groups B and C (P > 0.05). Improvement in WOMAC scores within all the 3 groups (P < 0.05) and SF-36 (P < 0.05). No statistically significant difference between the groups for VAS at rest (left P = 0.919, right P = 0.823) or activity (left P = 0.706, right P = 0.052) on both the sides and SF-36 scores (P > 0.05). Statistically significant difference between the groups for WOMAC (P = 0.043), Group A was better than Group C (P = 0.043). Conclusions: FW and BW along with conventional therapy are equally effective and not better than conventional treatment alone in reducing pain and improving physical function and QOL.

• Backward walking can be defined as a cyclic pattern of gait events. • Forward and Backward walking are affected by visual referencing in VR environments. • Backward walking in VR environments could potentially be a rehabilitation exercise. Backward walking is used increasingly as a rehabilitation exercise for stroke and diabetic peripheral neuropathy patients to improve strength and balance. However, it is unclear how visual referencing affects backward and forward walking. In this study, we evaluated spatiotemporal gait characteristics changes due to visual referencing while backward/forward walking. Sixteen healthy young participants were recruited in this study. All participants walked for 2 min with and without visual referencing in the virtual reality environment. While walking backward participants faced the virtual reality screen similar to forward walking, but their treadmill belt direction of movement was reversed. All participants walked at their preferred speed. We found that backward walking with visual reference affected symmetry in step length (p < 0.05) and step width (p < 0.001). Backward walking increased variability in step length (p < 0.001) and COM side excursions (p < 0.01) but also increased base of support through increased step width (p < 0.02). We also found backward walking with visual reference had significantly increased double support time (p < 0.001) and reduced swing time (p < 0.001). We also found that backward walking does not predispose to slip and trip risk, thereby, reduced foot contact velocity (p < 0.0001) and increased foot clearance (p < 0.0001). The findings of this study will help understand the effects of visual reference in backward and forward walking enables clinicians to design patient-centered rehabilitation exercises.

[Purpose] The purpose of the present study was to examine the effects of progressive body weight supported treadmill forward and backward walking training (PBWSTFBWT), progressive body weight supported treadmill forward walking training (PBWSTFWT), progressive body weight supported treadmill backward walking training (PBWSTBWT), on stroke patients' affected side lower extremity's walking ability. [Subjects and Methods] A total of 36 chronic stroke patients were divided into three groups with 12 subjects in each group. Each of the groups performed one of the progressive body weight supported treadmill training methods for 30 minute, six times per week for three weeks, and then received general physical therapy without any other intervention until the follow-up tests. For the assessment of the affected side lower extremity's walking ability, step length of the affected side, stance phase of the affected side, swing phase of the affected side, single support of the affected side, and step time of the affected side were measured using optogait and the symmetry index. [Results] In the within group comparisons, all the three groups showed significant differences between before and after the intervention and in the comparison of the three groups, the PBWSTFBWT group showed more significant differences in all of the assessed items than the other two groups. [Conclusion] In the present study progressive body weight supported treadmill training was performed in an environment in which the subjects were actually walked, and PBWSTFBWT was more effective at efficiently training stroke patients' affected side lower extremity's walking ability.
