  • In animals, proper locomotion is crucial to find mates and foods and avoid predators or dangers. Multiple sensory systems detect external and internal cues and integrate them to modulate motor outputs. Proprioception is the internal sense of body position, and proprioceptive control of locomotion is essential to generate and maintain precise patterns of movement or gaits. This proprioceptive feedback system is conserved in many animal species and is mediated by stretch-sensitive receptors called proprioceptors. Recent studies have identified multiple proprioceptive neurons and proprioceptors and their roles in the locomotion of various model organisms. In this review we describe molecular and neuronal mechanisms underlying proprioceptive feedback systems in C. elegans, Drosophila, and mice.

  • The purpose of this study was to investigate the effects of Proprioceptive Neuromuscular Facilitation (PNF) on the swallowing function of stroke patients. Twelve-week PNF (facial, tongue, and breathing exercise) was applied in the experimental group consisting of 12 subjects, and a general swallowing exercise program was applied to the control group consisting of 12 subjects. In addition, the signs of improvement in the stroke patients (N=24) swallowing function were examined by conducting a video fluoroscopic swallowing study. The data were analyzed using the SPSS ver. 21.0 program, which was also utilized to gain statistical information (percentage, mean, and standard deviation), and paired t-test was conducted. As a result of the analyses, the following conclusions were arrived at. The 12-week PNF significantly improved the functional dysphagia scale, penetration-aspiration scale, pharyngeal transit time, swallowing response time, residue in valleculae, and residue in pyriform sinuses enhanced swallowing functions of the stroke patients (p<.05). In conclusion, the PNF intervention in the swallowing function of the stroke patients was found to be an effective exercise program.

  • Purpose: This study aims to determine the effect of Jeonbuk tri-pull taping and proprioceptive neuromuscular facilitation (PNF) exercise on the shoulder's active range of motion, pain, subluxation, upper extremity function, and activities of daily living in patients with stroke. Methods: In this study, Jeonbuk tri-pull taping and PNF exercise were applied to three patients with stroke and subluxation. The tape was removed and new tape applied for two days every Monday, Wednesday, and Friday over six consecutive weeks. PNF exercise was applied five times a week for six weeks. To measure the range of motion, a smart phone clinometer application was used, and the degree of pain was measured using a visual analogue scale (VAS). A jig measuring method was employed to measure the distance of subluxation. The Fugl-Meyer Assessment (FMA) was used to evaluate arm function, and the modified Barthel Index (MBI) was employed to evaluate the activities of daily living. Results: The shoulder's active range of motion was improved in the patients compared to the range of pre-tests, and the pain and subluxation distance were reduced compared to those of pre-tests. Arm function and activities of daily living were increased compared to those of pre-tests. Conclusion: The study results verified that Jeonbuk tri-pull taping and PNF exercise are useful when applied to patients with subluxation and stroke.

  • Purpose: The purpose of this study was to investigate the effects of neck patterns in proprioceptive neuromuscular facilitation (PNF) for neck movement and the neck disability index (NDI) among adults with forward head posture. Methods: Thirty-nine subjects were randomly assigned into two groups. Subjects in the proprioceptive neuromuscular facilitation exercise group (PNFG, n = 20) received 20 minutes of PNF neck pattern (flexion-Rt. lateral flexion-Rt. rotation followed by extension-Lt. lateral flexion-Lt. rotation) 3 times weekly for 4 weeks. Outcomes were measured using absolute rotation angle (ARA), anterior weight bearing (AWB), range of flexion and extension motions (RFEM), and neck disability index (NDI) methods before and after the 4-week intervention period. Results: There were significant effects for the PNFG, pre- and post-intervention, in ARA, AWB, RFEM, and NDI. There were significant differences in ARA, AWB, RFEM, and NDI compared with CG. Conclusion: The results of this study suggest the PNF neck pattern could be beneficial for adults with forward head posture.Purpose: This study investigates how abdominal muscular exercise based on proprioceptive neuromuscular facilitation (PNF) can affect chronic low back pain patients in terms of their pulmonary function, pain, and functional disability indexes. Methods: Fourteen target subjects with chronic low back were randomly assigned to the control group (n = 7) that performed abdominal muscle exercises and the experimental group (n = 7) that performed PNF abdominal muscular exercises. The exercises were performed five times a week for six weeks. To check the change in pulmonary function, the forced expiratory volume at one second (FEV1) and visible analogue scale (VAS) were measured to check the pain level. The disability level caused by back pain was measured by the Oswestry Disability Index (ODI). A paired t-test was applied to compare the differences between the groups before and after the intervention, and an independent t-test was used to compare the differences between the groups. The level of statistical significance was set as ${\alpha}=0.05$. Results: Before and after the intervention, the experimental group showed a significant change in FEV1 (p < 0.01), and both the experimental and the control groups showed significant changes in VAS and ODI (p < 0.01). A comparison of the differences between the groups indicated that the experimental group showed more significant changes in FEV1 (p < 0.05). Conclusion: According to the study results, PNF abdominal muscular exercise effectively improved pulmonary function, pain, and functional disability indexes in subjects with chronic back pain. The proposed program can be applied to chronic back pain patients as a useful therapy.

  • PURPOSE: This study compared the effects of proprioceptive sensation, subacromial space, and dynamic function according to proprioceptive neuromuscular facilitation (PNF), static stretching (SS), and complex rotational stretching (CRS). METHODS: Thirty students without any musculoskeletal disease who volunteered to participate were included in this study. The following metrics were measured to evaluate the function and stability under the normal conditions, with the PNF, SS, and CRS: special test and flexion, extension, abduction, adduction, internal rotation, external rotation (shoulder range of motion) and reaching distance on the medial (ME), superolateral (SL), inferolateral (IL), and subacromial space and proprioceptive sensation were evaluated. All measures were analyzed using one-way ANOVA and repeated measures of ANOVA. RESULTS: A clear difference in adduction in the range of motion was observed in all groups (p < .05). Significant differences could not be identified in all values in the error test, except for Ab (p < .05). Significant differences in reach were noted in all directions of the SS and PNF in the Me, SL, and IL (p < .05). After the intervention, significant differences in the average values could be identified in all groups except for the SS group after rest (p < .05). After the intervention, there was a significant difference between the CRS and SS and PNF groups (p < .05). CONCLUSION: The application of CRS is as helpful as the existing SS and PNF for improving the joint range of motion improvement, shoulder balance, and subacromial space.

  • Purpose: The purpose of this study was to investigate the effects of forward-and-backward shift trunk exercise using a proprioceptive neuromuscular facilitation (PNF) diagonal pattern in a closed kinematic chain exercise on the upper limb function and activity of daily living (ADL) in a stroke patient. Methods: One subject participated in this study. The study used a reversal A-B-A' design, where A and A' were the baseline period (no intervention), and B was the intervention period. The intervention was a forward-and-backward trunk shift exercise, using a PNF diagonal pattern on both a stand-on-hand position and a quadruped position of closed kinematic chain exercises, for 20 min per day for 2 weeks. The range of motion (ROM) of the shoulder joint was measured and a Fugl-Meyer assessment of upper extremity (FMA-UE) and a functional independence measure (FIM) were performed to measure upper limb function and activity of daily living (ADL). Results: ROMs of shoulder joint (flexion, extension, abduction, and external rotation) increased in the intervention phase. The FMA-UE score increased (from 28 to 36) in the intervention phase. The FIM score increased (from 20 to 25) in the intervention phase. These increases were maintained after intervention (Baseline II). Conclusion: These results suggest that forward-and-backward shift trunk exercises using a PNF diagonal pattern in a closed kinematic chain exercise have a positive effect on stroke patients' upper limb function and ADL ability.
