BackgroundAlways carefully watching the climber, the belayer has to keep a position for a long time, which is damaging to the cervical spine. This often causes stiffness in the neck, which leads to cervical restrictions of motion. 3 types of belaying, the habitual belaying, the “CU glasses” and the “coordinated head position”, have been examined relating to their ability to avoid muscular tensions.Materials and methodsThe mobility of the cervical spine of 30 male and female climbers has been measured with an inclinometer immediately before and after defined belaying of 10 min. The subjects have been distributed to the 3 types of belaying at random. Additional the subjects had to answer questions concerning their personal feelings and a pain-rating-scale.ResultsWithin the group with habitual belaying, significant limitations in the mobility of the cervical spine in each direction could be determined, connected with strong pain after defined belaying. While using the “CU glasses” or “coordinated head posture”, no restrictions in movement (for each direction p>.05) has been noticed. Subjects that belayed with the “coordinated head posture” complained about backache because of the unfamiliar, active posture.ConclusionsDepending on the actual climbing-situation, the belayer should use either the „CU glasses“ or the „coordinated head posture“, in order to avoid muscular tension in the neck.Level of evidenceIIa 相似文献

Aims: This study evaluated, for youth with cerebral palsy (CP), the reliability of passive range of motion (PROM) measures taken with an inclinometer, a device that may be simpler to use than a goniometer. Methods: The PROM for elbow and wrist extension, ankle dorsal flexion (knee flexed 90° and fully extended), and the knee popliteal angle of 30 youth with CP (18 boys, 12 girls, 7.0?±?3.8 years old, classified in Gross Motor Function Classification levels I–V) was measured using an inclinometer. Two physical therapists took the measures during two different sessions, a maximum of 1 week apart. Results: Good mean intra-rater inter-session, inter-rater intra-session, and inter-rater inter-session reliability (ICC = 0.75–0.89), was found for the elbow, ankle, and knee sites. Absolute reliability for these sites and conditions was 7–14° (90% confident) and 10–16° (95% confident). Reliability values for wrist extension were comparable, albeit slight lower. Conclusions: Similar to published values for goniometry, inclinometery yields reliable upper and lower limb PROM measures from ambulatory and non-ambulatory youth with CP whether measures are carried out by different evaluators within or across sessions or whether measures are performed by the same evaluator across sessions. 相似文献

Background
Non‐specific low back pain is a common condition often without a clear mechanism for its presentation. Recently more attention has been placed on the hip and its potential contributions to non‐specific chronic low back pain (NSCLBP). Emphasis in research has mainly been placed on motor control, strength and endurance factors in relation to NSCLBP. Limited focus has been placed on hip mobility and its potential contribution in subjects with NSCLBP.Purpose/Aim
The aim of this study was to compare passive ROM in hip extension, hip internal rotation, hip external rotation and total hip rotation in active subjects with NSCLBP to healthy control subjects. The hypothesis was that active subjects with NSCLBP would present with decreased total hip ROM and greater asymmetry when compared to controls.Design
Two group case controlledSetting
Clinical research laboratoryParticipants
30 healthy subjects without NSCLBP and 30 active subjects with NSCLBP. Subjects categorized as NSCLBP were experiencing pain in the low back area with or without radicular symptoms of greater than three months duration.Main Outcome Measure
Passive hip extension (EXT), hip internal rotation (IR), hip external rotation (ER) and total hip rotation ROM. A digital inclinometer was used for measurements.Results
There was a statistically significant difference (p<0.001) in hip passive extension ROM between the control group and the NSCLBP group bilaterally. Mean hip extension for the control group was 6.88 bilaterally. For the NSCLBP group, the mean hip extension was ‐4.28 bilaterally. This corresponds to a difference of means between groups of 10.88. There was no statistically significant differences (p>0.05) in hip IR, ER, or total rotation ROM between groups.Conclusions
The results of this study indicate that a significant difference in hip extension exists in active subjects with NSCLBP compared to controls. It may be important to consider hip mobility restrictions and their potential impact on assessment of strength in NSLBP subjects. Future studies may be needed to investigate the relationship between measurements and intervention strategies.Level of Evidence

Background:
Electromagnetic tracking systems have enabled some investigators and clinicians to measure tri‐planar scapular motion; yet, they are not practical and affordable options for all clinicians. Currently, the ability to affordably quantify scapular motion is limited to monitoring only the motion of scapular upward rotation, with use of a digital inclinometer.Hypothesis/Purpose:
The objective of this study was to determine the criterion‐related validity of a modified digital inclinometer when used to measure the motion of scapular anterior‐posterior (AP) tilt.Materials & Methods:
Thirteen volunteers, free from any history of shoulder injury, reported for a single testing session. Each subject underwent a brief shoulder and posture examination in order to confirm the absence of pathology. Subjects actively performed clinically relevant amounts of humeral elevation in the scapular plane while in a seated position. An electromagnetic tracking system (Ascension Technology, Burlington, VT) and a modified inclinometer (Pro 360, Baseline®, Fabrication Enterprises, White Plains, NY) were used to acquire scapular AP tilt over the same shoulder motions. Criterion‐related validity was determined using Pearson Product Moment correlations.Results:
Correlation analyses revealed significant moderate to good associations (r = 0.63 to 0.86, p < 0.01) between scapular AP tilt measures obtained with a digital inclinometer and an electromagnetic tracking system.Conclusions
A modified digital inclinometer is a moderately valid device to use for the quantification of scapular AP tilt. Further study is warranted to establish reliability and to validate use of the device in patients with shoulder injury or pathology. The modified inclinometer expands the clinician''s ability to quantify scapular kinematic motion during the clinical evaluation and rehabilitation process.Level of Evidence:

Background and Purpose . Measurements of cervical range of motion (CROM) have been extensively reported in the past decade employing simple (goniometers) as well as sophisticated (electro‐, magneto‐ and ultrasonography‐based) systems. The recent introduction of the simple, user‐friendly and relatively cheap digital inclinometer (DI) has opened a potentially new venue for measurement of this segment's motion. The purpose of the present study was to assess intra‐tester reproducibility of DI‐based findings as well as its validity in comparison to the ultrasonography‐based Zebris CMS 70P (Zebris Medizintechnik Gmbh?, Isny, Germany) for measuring CROM in normal subjects. Methods . Active CROM of healthy women (n = 15) and men (n = 15) aged 24.2(2.4) years was measured on two sessions, Test 1 and Test 2, spread over 7.2(±0.7) days apart. On Test 1, the six primary movements of the neck (flexion, F; extension, E; right and left lateral flexion, RLF and LLF; and right and left rotations, RR and LR) were measured using the DI and the Zebris. On Test 2, the same measurements were performed using the DI only. All measurements were conducted by the same tester, with the subject in the seated position. The only exception was DI measurement of cervical rotation that was performed in the supine position due to the DI gravity‐dependence, rendering DI measurements in the transverse plane irrelevant. Results . No significant differences were revealed between the two instruments with respect to the sagittal and frontal planes, whereas the DI‐based CROM in rotation was significantly greater then its Zebris‐based counterpart. The inter‐device interclass correlation coefficients (ICCs) for the frontal were 0.72 (RLF) and 0.62 (LLF), and 0.77 (F) and 0.83 (E). Poor correlations were indicated for the rotations. The intra‐tester reproducibility derived from the test–retest DI measurement indicated good to excellent reproducibility in all planes with ICCs ranging from 0.82 (LLF) to 0.94 (E). The Standard Error of Measurement ranged from 1.6° (RR) to 2.6° (F). Conclusion . DI‐based CROM measurements are reproducible and valid for recording sagittal and frontal plane motions in healthy subjects. The higher range in rotations, relative to the Zebris‐based findings, is most probably attributable to the test position. Being relatively cheap, portable and convenient for tester and subject alike, the DI seems to be an effective instrument for assessing CROM. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
