Hybrid markerless tracking of complex articulated motion in golf swings

Sports video tracking is a research topic that has attained increasing attention due to its high commercial potential. A number of sports, including tennis, soccer, gymnastics, running, golf, badminton and cricket have been utilised to display the novel ideas in sports motion tracking. The main challenge associated with this research concerns the extraction of a highly complex articulated motion from a video scene. Our research focuses on the development of a markerless human motion tracking system that tracks the major body parts of an athlete straight from a sports broadcast video. We proposed a hybrid tracking method, which consists of a combination of three algorithms (pyramidal Lucas-Kanade optical flow (LK), normalised correlation-based template matching and background subtraction), to track the golfer's head, body, hands, shoulders, knees and feet during a full swing. We then match, track and map the results onto a 2D articulated human stick model to represent the pose of the golfer over time. Our work was tested using two video broadcasts of a golfer, and we obtained satisfactory results. The current outcomes of this research can play an important role in enhancing the performance of a golfer, provide vital information to sports medicine practitioners by providing technically sound guidance on movements and should assist to diminish the risk of golfing injuries.
Real-time stability measurement system for postural control

A method for assessing balance, which was sensitive to changes in the postural control system is presented. This paper describes the implementation of a force-sensing platform, with force sensing resistors as the sensing element. The platform is capable of measuring destabilized postural perturbations in dynamic and static postural conditions. Besides providing real-time qualitative assessment, the platform quantifies the postural control of the subjects. This is done by evaluating the weighted center of applied pressure distribution over time. The objective of this research was to establish the feasibility of using the force-sensing platform to test and gauge the postural control of individuals. Tests were conducted in Eye Open and Eye Close states on Flat Ground (static condition) and the balance trainer (dynamic condition). It was observed that the designed platform was able to gauge the sway experienced by the body when subject's states and conditions changed.
The effect of core stability training with ball and balloon exercise on respiratory variables in chronic non-specific low back pain: An experimental study

Mohan V, Paungmali A, Sitilertpisan P, Henry LJ, Omar FA, Azhar FZ

J Bodyw Mov Ther, 2020 Oct;24(4):196-202.

BACKGROUND: Studies have shown the involvement of respiratory characteristics and their relationship with impairments in non-specific low back pain (NS-LBP). The effects of core stability with a combined ball and balloon exercise (CBB) on respiratory variables had not been investigated.
OBJECTIVE: To evaluate the effectiveness of CBB on respiratory variables among NS-LBP patients.
STUDY DESIGN: pre- and post-experimental study.
PARTICIPANTS: Forty participants were assigned to an experimental group (EG) [n = 20] and control group (CG) [n = 20] based on the study criteria.
INTERVENTIONS: The EG received CBB together with routine physiotherapy and the CG received routine physiotherapy over a period of 8 weeks. Participants were instructed to carry out the exercises for 3 days per week. The training was evaluated once a week and the exercises progressed based on the level of pain.
OUTCOME MEASURES: Primary outcomes were maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) and maximum voluntary ventilation (MVV). The secondary outcomes were measured in the numeric rating scale (NRS), total faulty breathing scale (TFBS), cloth tape measure (CTM) and lumbo-pelvic stability.
RESULTS: The MIP increased significantly among the EG when compared with that in the CG (p > 0.05).The EG showed a significant increase in MVV (p = 0.04) when compared to the CG (p = 0.0001). There was a significant reduction in pain for both groups. The MEP, TFBS, chest expansion and core stability showed no changes in either group.
CONCLUSION: CBB was effective in improving respiratory variables among NS-LBP patients.

Therapeutic effects of connective tissue manipulation on wound healing and bacterial colonization count among patients with diabetic foot ulcer

This study investigated the therapeutic effects of connective tissue manipulation (CTM) in diabetic foot ulcer (DFU). A total of 20 participants (10 in CTM group and 10 in conventional treatment group (CG)) with DFU underwent the conventional DFU treatment. In addition, the CTM group received CTM twice per week for 6 weeks. The percentage wound area reduction (PWAR) and bacterial colonization count (BCC) in log10 colony-forming units (CFU) per ml wound fluid was evaluated at baseline and six weeks. Results showed a significant change in PWAR in CTM (p
Intra-rater and inter-rater reliability of total faulty breathing scale using visual observation and videogrammetry methods

Faulty breathing is an aspect of alteration in the normal fundamental pattern of breathing. The available existence of scales in assessing faulty breathing has not frequently been used. Measurement errors in assessing and quantifying breathing patterns may originate from unclear directions and variation between observers. This study determined the measure reliability of the Total Faulty Breathing Scale (TFBS) for quantifying breathing patterns. Twenty seven participants were recruited comprising healthy and unhealthy subjects. Two examiners assessed their breathing patterns using the TFBS on two different occasions with visual observation and a videogrammetry method. Evaluation of the observational breathing pattern method for intra-rater and inter-rater showed agreement of 96.30% and a kappa score of greater than 0.78, which indicated substantial agreements. The videogrammetry method showed a percent agreement of (100%) with a kappa score of (1.00). This study indicates that the TFBS is a considerably reliable tool for evaluating breathing patterns with both visual observation and a videogrammetry method.
