Effects of habitual knuckle cracking on metacarpal cartilage thickness and grip strength.

Joint cracking involves a manipulation of the finger joints resulting in an audible crack. This study aimed to determine whether habitual knuckle cracking (KC) leads to an alteration in grip strength and metacarpal head (MH) cartilage thickness. Thirty-five habitual knuckle crackers (cracking their joints ≥5times/day) (20 M, 15 F, aged 19-27 years) and 35 age-, gender-, and body mass index-matched non-crackers were enrolled in the study. MH cartilage thickness was measured with ultrasound and grip strength was measured with an analog Jamar hand dynamometer. Grip strength was similar between groups (P>0.05). Habitual knuckle crackers had thicker MH cartilage in the dominant and non-dominant hands than those of the controls (P=0.038 and P=0.005, respectively). There was no correlation between MH cartilage thickness and grip strength in both groups (P>0.05). While habitual KC does not affect handgrip strength, it appears to be associated with increased MH cartilage thickness.

Ultrasonographic Measurement of the Achilles and Supraspinatus Tendon Thicknesses in Patients with Chronic Lead Exposure.

OBJECTIVE: The study aimed to assess tendon thickness in patients with chronic occupational lead exposure by using ultrasonography. METHODS: Twenty-seven male workers (mean age 32.9 ± 6.2 years, range 25-44 years) with occupational lead exposure and 27 age- and body mass index (BMI)-matched healthy male subjects (mean age 33.1 ± 5.6 years, range 25-44 years) were enrolled. Ultrasonographic measurements were obtained from the supraspinatus and Achilles tendons by using a linear probe (5-10 MHz). RESULTS: Mean Achilles tendon values at long axis (p = 0.034) and tendon cross-sectional area (p = 0.013) were significantly smaller in the lead-exposed group than the control group. On the other hand, no significant difference was found regarding the thickness of the supraspinatus tendon (p > 0.05). CONCLUSION: Our preliminary results imply that subjects with occupational lead exposure have smaller Achilles tendons than healthy subjects. Chronic lead exposure may affect the tendons due to reduction of collagen synthesis. Further studies are definitely needed to confirm our initial findings.

Functional Outcomes of the Surgery and Rehabilitation in a Challenging Case of Heterotopic Ossification after Encephalitis.

Heterotopic ossification is the formation of the lamellar bone where normally osseous tissue does not exist. Since heterotopic ossification can cause severe functional loss, it is a challenging condition for both clinicians and patients. Neurogenic heterotopic ossification is a rare condition after encephalitis. Likewise, in this paper, we have presented a challenging case of heterotopic ossification after viral encephalitis and functional outcomes after the management of heterotopic ossification.

Does locomotor training improve pulmonary function in patients with spinal cord injury?

OBJECTIVES: The aim of this study was to compare the effects of a locomotor training (LT) combined rehabilitation program with a rehabilitation-only program on pulmonary function in spinal cord injury (SCI) patients by investigating spirometric analyses of the patients. SETTING: Rehabilitation center in Ankara, Turkey. METHODS: Fifty-two patients (40 male, 12 female) with SCI enrolled in the study. The subjects were divided into two groups: the first group (group A) received both LT and a rehabilitation program and the second group (group B) received only the rehabilitation program for 4 weeks. The LT program was prescribed as three 30-min sessions per week. Pulmonary function was evaluated spirometrically in both groups before and after the rehabilitation program. RESULTS: The spirometric values of the SCI patients, including forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow rate and vital capacity (VC) and VC%, increased significantly with LT in the first group (all P<0.05). Maximum voluntary ventilation values increased significantly in both groups (both P<0.05). CONCLUSION: These findings suggest that LT is effective for improving pulmonary function in SCI patients. We also highlight the useful effects of LT, which are likely the result of erect posture, gait and neuroplastic changes that prevent potential complications in SCI patients.

Wheelchair appropriateness in patients with spinal cord injury: a Turkish experience.

STUDY DESIGN: Descriptive. OBJECTIVE: To determine the wheelchair appropriateness in patients with spinal cord injury (SCI). SETTING: National Rehabilitation Center in Ankara, Turkey. METHODS: Twenty-seven (25 male, 2 female) SCI patients were included. Demographic and clinical characteristics of the patients were noted. All wheelchairs were evaluated considering each part (seat length, seat depth, seat height, back height, armrest, headrest, wheels and seat belt) by a physiatrist who had attended the wheelchair-training course. The wheelchair was declared as inappropriate if at least three parts of wheelchair were not appropriate. RESULTS: The mean age of the patients was 32.9±9.3 years and mean duration of wheelchair use was 19.63±23.02 months. Among the patients, 21 (77.8%) were American Spinal Injury Association Impairment Scale (AIS) A, 4 (3.7%) AIS B, 1 (3.7%) AIS C and 1 (3.7%) AIS D. Five (18.5%) wheelchairs were motorized and 22 (81.5%) were manual. Overall, 15 (55.6%) wheelchairs were inappropriate. Seat height, cushion and back height were the most common inappropriate parts. CONCLUSION: In light of our first and preliminary results, we can argue that 55% of the patients with SCI use inappropriate wheelchairs. In order to achieve better mobility; personally designed wheelchairs should be prescribed by the clinicians.
